Essay on Sustainable Development: Samples in 250, 300 and 500 Words

• Updated on  
• Nov 18, 2023

On 3rd August 2023, the Indian Government released its Net zero emissions target policy to reduce its carbon footprints. To achieve the sustainable development goals (SDG) , as specified by the UN, India is determined for its long-term low-carbon development strategy. Selfishly pursuing modernization, humans have frequently compromised with the requirements of a more sustainable environment.

As a result, the increased environmental depletion is evident with the prevalence of deforestation, pollution, greenhouse gases, climate change etc. To combat these challenges, the Ministry of Environment, Forest and Climate Change launched the National Clean Air Programme (NCAP) in 2019. The objective was to improve air quality in 131 cities in 24 States/UTs by engaging multiple stakeholders.

‘Development is not real until and unless it is sustainable development.’ – Ban Ki-Moon

The importance of sustainable development is that it meets the needs of the present generations without compromising on the needs of the coming future generations. Sustainable development teaches us to use our resources in the correct manner. Listed below are some points which tell us the importance of sustainable development.

• Focuses on Sustainable Agricultural Methods – Sustainable development is important because it takes care of the needs of future generations and makes sure that the increasing population does not put a burden on Mother Earth. It promotes agricultural techniques such as crop rotation and effective seeding techniques.
• Manages Stabilizing the Climate – We are facing the problem of climate change due to the excessive use of fossil fuels and the killing of the natural habitat of animals. Sustainable development plays a major role in preventing climate change by developing practices that are sustainable. It promotes reducing the use of fossil fuels which release greenhouse gases that destroy the atmosphere.
• Provides Important Human Needs – Sustainable development promotes the idea of saving for future generations and making sure that resources are allocated to everybody. It is based on the principle of developing an infrastructure that is can be sustained for a long period of time.
• Sustain Biodiversity – If the process of sustainable development is followed, the home and habitat of all other living animals will not be depleted. As sustainable development focuses on preserving the ecosystem it automatically helps in sustaining and preserving biodiversity.
• Financial Stability – As sustainable development promises steady development the economies of countries can become stronger by using renewable sources of energy as compared to using fossil fuels, of which there is only a particular amount on our planet.

Mentioned below are some important examples of sustainable development. Have a look:

• Wind Energy – Wind energy is an easily available resource. It is also a free resource. It is a renewable source of energy and the energy which can be produced by harnessing the power of wind will be beneficial for everyone. Windmills can produce energy which can be used to our benefit. It can be a helpful source of reducing the cost of grid power and is a fine example of sustainable development. 
• Solar Energy – Solar energy is also a source of energy which is readily available and there is no limit to it. Solar energy is being used to replace and do many things which were first being done by using non-renewable sources of energy. Solar water heaters are a good example. It is cost-effective and sustainable at the same time.
• Crop Rotation – To increase the potential of growth of gardening land, crop rotation is an ideal and sustainable way. It is rid of any chemicals and reduces the chances of disease in the soil. This form of sustainable development is beneficial to both commercial farmers and home gardeners.
• Efficient Water Fixtures – The installation of hand and head showers in our toilets which are efficient and do not waste or leak water is a method of conserving water. Water is essential for us and conserving every drop is important. Spending less time under the shower is also a way of sustainable development and conserving water.
• Sustainable Forestry – This is an amazing way of sustainable development where the timber trees that are cut by factories are replaced by another tree. A new tree is planted in place of the one which was cut down. This way, soil erosion is prevented and we have hope of having a better, greener future.

THE SDGS IN ACTION.

What are the sustainable development goals.

The Sustainable Development Goals (SDGs), also known as the Global Goals, were adopted by the United Nations in 2015 as a universal call to action to end poverty, protect the planet, and ensure that by 2030 all people enjoy peace and prosperity.

The 17 SDGs are integrated—they recognize that action in one area will affect outcomes in others, and that development must balance social, economic and environmental sustainability.

Countries have committed to prioritize progress for those who're furthest behind. The SDGs are designed to end poverty, hunger, AIDS, and discrimination against women and girls.

The creativity, knowhow, technology and financial resources from all of society is necessary to achieve the SDGs in every context.

Eradicating poverty in all its forms remains one of the greatest challenges facing humanity. While the number of people living in extreme poverty dropped by more than half between 1990 and 2015, too many are still struggling for the most basic human needs.

As of 2015, about 736 million people still lived on less than US$1.90 a day; many lack food, clean drinking water and sanitation. Rapid growth in countries such as China and India has lifted millions out of poverty, but progress has been uneven. Women are more likely to be poor than men because they have less paid work, education, and own less property.

Progress has also been limited in other regions, such as South Asia and sub-Saharan Africa, which account for 80 percent of those living in extreme poverty. New threats brought on by climate change, conflict and food insecurity, mean even more work is needed to bring people out of poverty.

The SDGs are a bold commitment to finish what we started, and end poverty in all forms and dimensions by 2030. This involves targeting the most vulnerable, increasing basic resources and services, and supporting communities affected by conflict and climate-related disasters.

736 million people still live in extreme poverty.

10 percent of the world’s population live in extreme poverty, down from 36 percent in 1990.

Some 1.3 billion people live in multidimensional poverty.

Half of all people living in poverty are under 18.

One person in every 10 is extremely poor.

Goal targets

• By 2030, reduce at least by half the proportion of men, women and children of all ages living in poverty in all its dimensions according to national definitions
• Implement nationally appropriate social protection systems and measures for all, including floors, and by 2030 achieve substantial coverage of the poor and the vulnerable
• By 2030, ensure that all men and women, in particular the poor and the vulnerable, have equal rights to economic resources, as well as access to basic services, ownership and control over land and other forms of property, inheritance, natural resources, appropriate new technology and financial services, including microfinance
• By 2030, build the resilience of the poor and those in vulnerable situations and reduce their exposure and vulnerability to climate-related extreme events and other economic, social and environmental shocks and disasters
• Ensure significant mobilization of resources from a variety of sources, including through enhanced development cooperation, in order to provide adequate and predictable means for developing countries, in particular least developed countries, to implement programmes and policies to end poverty in all its dimensions
• Create sound policy frameworks at the national, regional and international levels, based on pro-poor and gender-sensitive development strategies, to support accelerated investment in poverty eradication actions

Zero Hunger

The number of undernourished people has dropped by almost half in the past two decades because of rapid economic growth and increased agricultural productivity. Many developing countries that used to suffer from famine and hunger can now meet their nutritional needs. Central and East Asia, Latin America and the Caribbean have all made huge progress in eradicating extreme hunger.

Unfortunately, extreme hunger and malnutrition remain a huge barrier to development in many countries. There are 821 million people estimated to be chronically undernourished as of 2017, often as a direct consequence of environmental degradation, drought and biodiversity loss. Over 90 million children under five are dangerously underweight. Undernourishment and severe food insecurity appear to be increasing in almost all regions of Africa, as well as in South America.

The SDGs aim to end all forms of hunger and malnutrition by 2030, making sure all people–especially children–have sufficient and nutritious food all year. This involves promoting sustainable agricultural, supporting small-scale farmers and equal access to land, technology and markets. It also requires international cooperation to ensure investment in infrastructure and technology to improve agricultural productivity.

The number of undernourished people reached 821 million in 2017.

In 2017 Asia accounted for nearly two thirds, 63 percent, of the world’s hungry.

Nearly 151 million children under five, 22 percent, were still stunted in 2017.

More than 1 in 8 adults is obese.

1 in 3 women of reproductive age is anemic.

26 percent of workers are employed in agriculture.

• By 2030, end all forms of malnutrition, including achieving, by 2025, the internationally agreed targets on stunting and wasting in children under 5 years of age, and address the nutritional needs of adolescent girls, pregnant and lactating women and older persons
• By 2030, double the agricultural productivity and incomes of small-scale food producers, in particular women, indigenous peoples, family farmers, pastoralists and fishers, including through secure and equal access to land, other productive resources and inputs, knowledge, financial services, markets and opportunities for value addition and non-farm employment
• By 2030, ensure sustainable food production systems and implement resilient agricultural practices that increase productivity and production, that help maintain ecosystems, that strengthen capacity for adaptation to climate change, extreme weather, drought, flooding and other disasters and that progressively improve land and soil quality
• By 2020, maintain the genetic diversity of seeds, cultivated plants and farmed and domesticated animals and their related wild species, including through soundly managed and diversified seed and plant banks at the national, regional and international levels, and promote access to and fair and equitable sharing of benefits arising from the utilization of genetic resources and associated traditional knowledge, as internationally agreed
• Increase investment, including through enhanced international cooperation, in rural infrastructure, agricultural research and extension services, technology development and plant and livestock gene banks in order to enhance agricultural productive capacity in developing countries, in particular least developed countries
• Correct and prevent trade restrictions and distortions in world agricultural markets, including through the parallel elimination of all forms of agricultural export subsidies and all export measures with equivalent effect, in accordance with the mandate of the Doha Development Round
• Adopt measures to ensure the proper functioning of food commodity markets and their derivatives and facilitate timely access to market information, including on food reserves, in order to help limit extreme food price volatility.

Good health and well-being.

We have made great progress against several leading causes of death and disease. Life expectancy has increased dramatically; infant and maternal mortality rates have declined, we’ve turned the tide on HIV and malaria deaths have halved.

Good health is essential to sustainable development and the 2030 Agenda reflects the complexity and interconnectedness of the two. It takes into account widening economic and social inequalities, rapid urbanization, threats to the climate and the environment, the continuing burden of HIV and other infectious diseases, and emerging challenges such as noncommunicable diseases. Universal health coverage will be integral to achieving SDG 3, ending poverty and reducing inequalities. Emerging global health priorities not explicitly included in the SDGs, including antimicrobial resistance, also demand action.

But the world is off-track to achieve the health-related SDGs. Progress has been uneven, both between and within countries. There’s a 31-year gap between the countries with the shortest and longest life expectancies. And while some countries have made impressive gains, national averages hide that many are being left behind. Multisectoral, rights-based and gender-sensitive approaches are essential to address inequalities and to build good health for all.

At least 400 million people have no basic healthcare, and 40 percent lack social protection.

More than 1.6 billion people live in fragile settings where protracted crises, combined with weak national capacity to deliver basic health services, present a significant challenge to global health.

By the end of 2017, 21.7 million people living with HIV were receiving antiretroviral therapy. Yet more than 15 million people are still waiting for treatment.

Every 2 seconds someone aged 30 to 70 years dies prematurely from noncommunicable diseases - cardiovascular disease, chronic respiratory disease, diabetes or cancer.

7 million people die every year from exposure to fine particles in polluted air.

More than one of every three women have experienced either physical or sexual violence at some point in their life resulting in both short- and long-term consequences for their physical, mental, and sexual and reproductive health.

• By 2030, reduce the global maternal mortality ratio to less than 70 per 100,000 live births
• By 2030, end preventable deaths of newborns and children under 5 years of age, with all countries aiming to reduce neonatal mortality to at least as low as 12 per 1,000 live births and under-5 mortality to at least as low as 25 per 1,000 live births
• By 2030, end the epidemics of AIDS, tuberculosis, malaria and neglected tropical diseases and combat hepatitis, water-borne diseases and other communicable diseases
• By 2030, reduce by one third premature mortality from non-communicable diseases through prevention and treatment and promote mental health and well-being
• Strengthen the prevention and treatment of substance abuse, including narcotic drug abuse and harmful use of alcohol
• By 2020, halve the number of global deaths and injuries from road traffic accidents
• By 2030, ensure universal access to sexual and reproductive health-care services, including for family planning, information and education, and the integration of reproductive health into national strategies and programmes
• Achieve universal health coverage, including financial risk protection, access to quality essential health-care services and access to safe, effective, quality and affordable essential medicines and vaccines for all
• By 2030, substantially reduce the number of deaths and illnesses from hazardous chemicals and air, water and soil pollution and contamination
• Strengthen the implementation of the World Health Organization Framework Convention on Tobacco Control in all countries, as appropriate
• Support the research and development of vaccines and medicines for the communicable and noncommunicable diseases that primarily affect developing countries, provide access to affordable essential medicines and vaccines, in accordance with the Doha Declaration on the TRIPS Agreement and Public Health, which affirms the right of developing countries to use to the full the provisions in the Agreement on Trade Related Aspects of Intellectual Property Rights regarding flexibilities to protect public health, and, in particular, provide access to medicines for all
• Substantially increase health financing and the recruitment, development, training and retention of the health workforce in developing countries, especially in least developed countries and small island developing States
• Strengthen the capacity of all countries, in particular developing countries, for early warning, risk reduction and management of national and global health risks

Quality education.

Since 2000, there has been enormous progress in achieving the target of universal primary education. The total enrollment rate in developing regions reached 91 percent in 2015, and the worldwide number of children out of school has dropped by almost half. There has also been a dramatic increase in literacy rates, and many more girls are in school than ever before. These are all remarkable successes.

Progress has also been tough in some developing regions due to high levels of poverty, armed conflicts and other emergencies. In Western Asia and North Africa, ongoing armed conflict has seen an increase in the number of children out of school. This is a worrying trend. While Sub-Saharan Africa made the greatest progress in primary school enrollment among all developing regions – from 52 percent in 1990, up to 78 percent in 2012 – large disparities still remain. Children from the poorest households are up to four times more likely to be out of school than those of the richest households. Disparities between rural and urban areas also remain high.

Achieving inclusive and quality education for all reaffirms the belief that education is one of the most powerful and proven vehicles for sustainable development. This goal ensures that all girls and boys complete free primary and secondary schooling by 2030. It also aims to provide equal access to affordable vocational training, to eliminate gender and wealth disparities, and achieve universal access to a quality higher education.

Enrollment in primary education in developing countries has reached 91 percent.

Still, 57 million primary-aged children remain out of school, more than half of them in sub-Saharan Africa.

In developing countries, one in four girls is not in school.

About half of all out-of-school children of primary school age live in conflict-affected areas.

103 million youth worldwide lack basic literacy skills, and more than 60 percent of them are women.

6 out of 10 children and adolescents are not achieving a minimum level of proficiency in reading and math.

• By 2030, ensure that all girls and boys complete free, equitable and quality primary and secondary education leading to relevant and Goal-4 effective learning outcomes
• By 2030, ensure that all girls and boys have access to quality early childhood development, care and preprimary education so that they are ready for primary education
• By 2030, ensure equal access for all women and men to affordable and quality technical, vocational and tertiary education, including university
• By 2030, substantially increase the number of youth and adults who have relevant skills, including technical and vocational skills, for employment, decent jobs and entrepreneurship
• By 2030, eliminate gender disparities in education and ensure equal access to all levels of education and vocational training for the vulnerable, including persons with disabilities, indigenous peoples and children in vulnerable situations
• By 2030, ensure that all youth and a substantial proportion of adults, both men and women, achieve literacy and numeracy
• By 2030, ensure that all learners acquire the knowledge and skills needed to promote sustainable development, including, among others, through education for sustainable development and sustainable lifestyles, human rights, gender equality, promotion of a culture of peace and non-violence, global citizenship and appreciation of cultural diversity and of culture’s contribution to sustainable development
• Build and upgrade education facilities that are child, disability and gender sensitive and provide safe, nonviolent, inclusive and effective learning environments for all
• By 2020, substantially expand globally the number of scholarships available to developing countries, in particular least developed countries, small island developing States and African countries, for enrolment in higher education, including vocational training and information and communications technology, technical, engineering and scientific programmes, in developed countries and other developing countries
• By 2030, substantially increase the supply of qualified teachers, including through international cooperation for teacher training in developing countries, especially least developed countries and small island developing states

Gender equality.

Gender Equality

Ending all discrimination against women and girls is not only a basic human right, it’s crucial for sustainable future; it’s proven that empowering women and girls helps economic growth and development.

UNDP has made gender equality central to its work and we’ve seen remarkable progress in the past 20 years. There are more girls in school now compared to 15 years ago, and most regions have reached gender parity in primary education.

But although there are more women than ever in the labour market, there are still large inequalities in some regions, with women systematically denied the same work rights as men. Sexual violence and exploitation, the unequal division of unpaid care and domestic work, and discrimination in public office all remain huge barriers. Climate change and disasters continue to have a disproportionate effect on women and children, as do conflict and migration.

It is vital to give women equal rights land and property, sexual and reproductive health, and to technology and the internet. Today there are more women in public office than ever before, but encouraging more women leaders will help achieve greater gender equality.

Women earn only 77 cents for every dollar that men get for the same work.

35 percent of women have experienced physical and/or sexual violence.

Women represent just 13 percent of agricultural landholders.

Almost 750 million women and girls alive today were married before their 18th birthday.

Two thirds of developing countries have achieved gender parity in primary education.

Only 24 percent of national parliamentarians were women as of November 2018, a small increase from 11.3 percent in 1995.

• End all forms of discrimination against all women and girls everywhere
• Eliminate all forms of violence against all women and girls in the public and private spheres, including trafficking and sexual and other types of exploitation
• Eliminate all harmful practices, such as child, early and forced marriage and female genital mutilation
• Recognize and value unpaid care and domestic work through the provision of public services, infrastructure and social protection policies and the promotion of shared responsibility within the household and the family as nationally appropriate
• Ensure women’s full and effective participation and equal opportunities for leadership at all levels of decisionmaking in political, economic and public life
• Ensure universal access to sexual and reproductive health and reproductive rights as agreed in accordance with the Programme of Action of the International Conference on Population and Development and the Beijing Platform for Action and the outcome documents of their review conferences
• Undertake reforms to give women equal rights to economic resources, as well as access to ownership and control over land and other forms of property, financial services, inheritance and natural resources, in accordance with national laws
• Enhance the use of enabling technology, in particular information and communications technology, to promote the empowerment of women
• Adopt and strengthen sound policies and enforceable legislation for the promotion of gender equality and the empowerment of all women and girls at all levels

Clean water and sanitation.

Water scarcity affects more than 40 percent of people, an alarming figure that is projected to rise as temperatures do. Although 2.1 billion people have improved water sanitation since 1990, dwindling drinking water supplies are affecting every continent.

More and more countries are experiencing water stress, and increasing drought and desertification is already worsening these trends. By 2050, it is projected that at least one in four people will suffer recurring water shortages.

Safe and affordable drinking water for all by 2030 requires we invest in adequate infrastructure, provide sanitation facilities, and encourage hygiene. Protecting and restoring water-related ecosystems is essential.

Ensuring universal safe and affordable drinking water involves reaching over 800 million people who lack basic services and improving accessibility and safety of services for over two billion.

In 2015, 4.5 billion people lacked safely managed sanitation services (with adequately disposed or treated excreta) and 2.3 billion lacked even basic sanitation.

71 percent of the global population, 5.2 billion people, had safely-managed drinking water in 2015, but 844 million people still lacked even basic drinking water.

39 percent of the global population, 2.9 billion people, had safe sanitation in 2015, but 2.3 billion people still lacked basic sanitation. 892 million people practiced open defecation.

80 percent of wastewater goes into waterways without adequate treatment.

Water stress affects more than 2 billion people, with this figure projected to increase.

80 percent of countries have laid the foundations for integrated water resources management.

The world has lost 70 percent of its natural wetlands over the last century.

• By 2030, achieve universal and equitable access to safe and affordable drinking water for all
• By 2030, achieve access to adequate and equitable sanitation and hygiene for all and end open defecation, paying special attention to the needs of women and girls and those in vulnerable situations
• By 2030, improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally
• By 2030, substantially increase water-use efficiency across all sectors and ensure sustainable withdrawals and supply of freshwater to address water scarcity and substantially reduce the number of people suffering from water scarcity
• By 2030, implement integrated water resources management at all levels, including through transboundary cooperation as appropriate
• By 2020, protect and restore water-related ecosystems, including mountains, forests, wetlands, rivers, aquifers and lakes
• By 2030, expand international cooperation and capacity-building support to developing countries in water- and sanitation-related activities and programmes, including water harvesting, desalination, water efficiency, wastewater treatment, recycling and reuse technologies
• Support and strengthen the participation of local communities in improving water and sanitation management

Affordable and clean energy.

Between 2000 and 2018, the number of people with electricity increased from 78 to 90 percent, and the numbers without electricity dipped to 789 million.

Yet as the population continues to grow, so will the demand for cheap energy, and an economy reliant on fossil fuels is creating drastic changes to our climate.

Investing in solar, wind and thermal power, improving energy productivity, and ensuring energy for all is vital if we are to achieve SDG 7 by 2030.

Expanding infrastructure and upgrading technology to provide clean and more efficient energy in all countries will encourage growth and help the environment.  

One out of 10 people still lacks electricity, and most live in rural areas of the developing world. More than half are in sub-Saharan Africa.

Energy is by far the main contributor to climate change. It accounts for 73 percent of human-caused greenhouse gases.

Energy efficiency is key; the right efficiency policies could enable the world to achieve more than 40 percent of the emissions cuts needed to reach its climate goals without new technology.

Almost a third of the world’s population—2.8 billion—rely on polluting and unhealthy fuels for cooking.

As of 2017, 17.5 percent of power was generated through renewable sources.

The renewable energy sector employed a record 11.5 million people in 2019. The changes needed in energy production and uses to achieve the Paris Agreement target of limiting the rise in temperature to below 2C can create 18 million jobs.

• By 2030, ensure universal access to affordable, reliable and modern energy services
• By 2030, increase substantially the share of renewable energy in the global energy mix
• By 2030, double the global rate of improvement in energy efficiency
• By 2030, enhance international cooperation to facilitate access to clean energy research and technology, including renewable energy, energy efficiency and advanced and cleaner fossil-fuel technology, and promote investment in energy infrastructure and clean energy technology
• By 2030, expand infrastructure and upgrade technology for supplying modern and sustainable energy services for all in developing countries, in particular least developed countries, small island developing States, and land-locked developing coun

Decent work and economic growth.

Over the past 25 years the number of workers living in extreme poverty has declined dramatically, despite the lasting impact of the 2008 economic crisis and global recession. In developing countries, the middle class now makes up more than 34 percent of total employment – a number that has almost tripled between 1991 and 2015.

However, as the global economy continues to recover we are seeing slower growth, widening inequalities, and not enough jobs to keep up with a growing labour force. According to the International Labour Organization, more than 204 million people were unemployed in 2015.

The SDGs promote sustained economic growth, higher levels of productivity and technological innovation. Encouraging entrepreneurship and job creation are key to this, as are effective measures to eradicate forced labour, slavery and human trafficking. With these targets in mind, the goal is to achieve full and productive employment, and decent work, for all women and men by 2030.

An estimated 172 million people worldwide were without work in 2018 - an unemployment rate of 5 percent.

As a result of an expanding labour force, the number of unemployed is projected to increase by 1 million every year and reach 174 million by 2020.

Some 700 million workers lived in extreme or moderate poverty in 2018, with less than US$3.20 per day.

Women’s participation in the labour force stood at 48 per cent in 2018, compared with 75 percent for men. Around 3 in 5 of the 3.5 billion people in the labour force in 2018 were men.

Overall, 2 billion workers were in informal employment in 2016, accounting for 61 per cent of the world’s workforce.

Many more women than men are underutilized in the labour force—85 million compared to 55 million.

Industry, innovation and infrastructure.

Investment in infrastructure and innovation are crucial drivers of economic growth and development. With over half the world population now living in cities, mass transport and renewable energy are becoming ever more important, as are the growth of new industries and information and communication technologies.

Technological progress is also key to finding lasting solutions to both economic and environmental challenges, such as providing new jobs and promoting energy efficiency. Promoting sustainable industries, and investing in scientific research and innovation, are all important ways to facilitate sustainable development.

More than 4 billion people still do not have access to the Internet, and 90 percent are from the developing world. Bridging this digital divide is crucial to ensure equal access to information and knowledge, as well as foster innovation and entrepreneurship.   

Worldwide, 2.3 billion people lack access to basic sanitation.

In some low-income African countries, infrastructure constraints cut businesses’ productivity by around 40 percent.

2.6 billion people in developing countries do not have access to constant electricity.

More than 4 billion people still do not have access to the Internet; 90 percent of them are in the developing world.

The renewable energy sectors currently employ more than 2.3 million people; the number could reach 20 million by 2030.

In developing countries, barely 30 percent of agricultural products undergo industrial processing, compared to 98 percent high-income countries.

• Develop quality, reliable, sustainable and resilient infrastructure, including regional and transborder infrastructure, to support economic development and human well-being, with a focus on affordable and equitable access for all
• Promote inclusive and sustainable industrialization and, by 2030, significantly raise industry’s share of employment and gross domestic product, in line with national circumstances, and double its share in least developed countries
• Increase the access of small-scale industrial and other enterprises, in particular in developing countries, to financial services, including affordable credit, and their integration into value chains and markets
• By 2030, upgrade infrastructure and retrofit industries to make them sustainable, with increased resource-use efficiency and greater adoption of clean and environmentally sound technologies and industrial processes, with all countries taking action in accordance with their respective capabilities

Reduced inequalities.

Income inequality is on the rise—the richest 10 percent have up to 40 percent of global income whereas the poorest 10 percent earn only between 2 to 7 percent. If we take into account population growth inequality in developing countries, inequality has increased by 11 percent.

Income inequality has increased in nearly everywhere in recent decades, but at different speeds. It’s lowest in Europe and highest in the Middle East.

These widening disparities require sound policies to empower lower income earners, and promote economic inclusion of all regardless of sex, race or ethnicity.

Income inequality requires global solutions. This involves improving the regulation and monitoring of financial markets and institutions, encouraging development assistance and foreign direct investment to regions where the need is greatest. Facilitating the safe migration and mobility of people is also key to bridging the widening divide.

In 2016, 22 percent of global income was received by the top 1 percent compared with 10 percent of income for the bottom 50 percent.

In 1980, the top one percent had 16 percent of global income. The bottom 50 percent had 8 percent of income.

Economic inequality is largely driven by the unequal ownership of capital. Since 1980, very large transfers of public to private wealth occurred in nearly all countries. The global wealth share of the top 1 percent was 33 percent in 2016.

Under "business as usual", the top 1 percent global wealth will reach 39 percent by 2050.

Women spend, on average, twice as much time on unpaid housework as men.

Women have as much access to financial services as men in just 60 percent of the countries assessed and to land ownership in just 42 percent of the countries assessed.

• By 2030, progressively achieve and sustain income growth of the bottom 40 per cent of the population at a rate higher than the national average
• By 2030, empower and promote the social, economic and political inclusion of all, irrespective of age, sex, disability, race, ethnicity, origin, religion or economic or other status
• Ensure equal opportunity and reduce inequalities of outcome, including by eliminating discriminatory laws, policies and practices and promoting appropriate legislation, policies and action in this regard
• Adopt policies, especially fiscal, wage and social protection policies, and progressively achieve greater equality
• Improve the regulation and monitoring of global financial markets and institutions and strengthen the implementation of such regulations
• Ensure enhanced representation and voice for developing countries in decision-making in global international economic and financial institutions in order to deliver more effective, credible, accountable and legitimate institutions
• Facilitate orderly, safe, regular and responsible migration and mobility of people, including through the implementation of planned and well-managed migration policies
• Implement the principle of special and differential treatment for developing countries, in particular least developed countries, in accordance with World Trade Organization agreements
• Encourage official development assistance and financial flows, including foreign direct investment, to States where the need is greatest, in particular least developed countries, African countries, small island developing States and landlocked developing countries, in accordance with their national plans and programmes
• By 2030, reduce to less than 3 per cent the transaction costs of migrant remittances and eliminate remittance corridors with costs higher than 5 per cent

Sustainable cities and communities.

More than half of us  live in cities. By 2050, two-thirds of all humanity—6.5 billion people—will be urban. Sustainable development cannot be achieved without significantly transforming the way we build and manage our urban spaces.

The rapid growth of cities—a result of rising populations and increasing migration—has led to a boom in mega-cities, especially in the developing world, and slums are becoming a more significant feature of urban life.

Making cities sustainable means creating career and business opportunities, safe and affordable housing, and building resilient societies and economies. It involves investment in public transport, creating green public spaces, and improving urban planning and management in participatory and inclusive ways.

In 2018, 4.2 billion people, 55 percent of the world’s population, lived in cities. By 2050, the urban population is expected to reach 6.5 billion.

Cities occupy just 3 percent of the Earth’s land but account for 60 to 80 percent of energy consumption and at least 70 percent of carbon emissions.

828 million people are estimated to live in slums, and the number is rising.

In 1990, there were 10 cities with 10 million people or more; by 2014, the number of mega-cities rose to 28, and was expected to reach 33 by 2018. In the future, 9 out of 10 mega-cities will be in the developing world.

In the coming decades, 90 percent of urban expansion will be in the developing world.

The economic role of cities is significant. They generate about 80 percent of the global GDP.

• By 2030, ensure access for all to adequate, safe and affordable housing and basic services and upgrade slums
• By 2030, provide access to safe, affordable, accessible and sustainable transport systems for all, improving road safety, notably by expanding public transport, with special attention to the needs of those in vulnerable situations, women, children, persons with disabilities and older persons
• By 2030, enhance inclusive and sustainable urbanization and capacity for participatory, integrated and sustainable human settlement planning and management in all countries
• Strengthen efforts to protect and safeguard the world’s cultural and natural heritage
• By 2030, significantly reduce the number of deaths and the number of people affected and substantially decrease the direct economic losses relative to global gross domestic product caused by disasters, including water-related disasters, with a focus on protecting the poor and people in vulnerable situations
• By 2030, reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management
• By 2030, provide universal access to safe, inclusive and accessible, green and public spaces, in particular for women and children, older persons and persons with disabilities
• Support positive economic, social and environmental links between urban, peri-urban and rural areas by strengthening national and regional development planning

Responsible consumption and production.

Achieving economic growth and sustainable development requires that we urgently reduce our ecological footprint by changing the way we produce and consume goods and resources. Agriculture is the biggest user of water worldwide, and irrigation now claims close to 70 percent of all freshwater for human use.

The efficient management of our shared natural resources, and the way we dispose of toxic waste and pollutants, are important targets to achieve this goal. Encouraging industries, businesses and consumers to recycle and reduce waste is equally important, as is supporting developing countries to move towards more sustainable patterns of consumption by 2030.

A large share of the world population is still consuming far too little to meet even their basic needs.  Halving the per capita of global food waste at the retailer and consumer levels is also important for creating more efficient production and supply chains. This can help with food security, and shift us towards a more resource efficient economy.

1.3 billion tonnes of food is wasted every year, while almost 2 billion people go hungry or undernourished.

The food sector accounts for around 22 percent of total greenhouse gas emissions, largely from the conversion of forests into farmland.

Globally, 2 billion people are overweight or obese.

Only 3 percent of the world’s water is fresh (drinkable), and humans are using it faster than nature can replenish it.

If people everywhere switched to energy efficient lightbulbs, the world would save US$120 billion annually.

One-fifth of the world’s final energy consumption in 2013 was from renewable sources.

• Implement the 10-year framework of programmes on sustainable consumption and production, all countries taking action, with developed countries taking the lead, taking into account the development and capabilities of developing countries
• By 2030, achieve the sustainable management and efficient use of natural resources
• By 2030, halve per capita global food waste at the retail and consumer levels and reduce food losses along production and supply chains, including post-harvest losses
• By 2020, achieve the environmentally sound management of chemicals and all wastes throughout their life cycle, in accordance with agreed international frameworks, and significantly reduce their release to air, water and soil in order to minimize their adverse impacts on human health and the environment
• By 2030, substantially reduce waste generation through prevention, reduction, recycling and reuse
• Encourage companies, especially large and transnational companies, to adopt sustainable practices and to integrate sustainability information into their reporting cycle
• Promote public procurement practices that are sustainable, in accordance with national policies and priorities
• By 2030, ensure that people everywhere have the relevant information and awareness for sustainable development and lifestyles in harmony with nature
• Support developing countries to strengthen their scientific and technological capacity to move towards more sustainable patterns of consumption and production
• Develop and implement tools to monitor sustainable development impacts for sustainable tourism that creates jobs and promotes local culture and products
• Rationalize inefficient fossil-fuel subsidies that encourage wasteful consumption by removing market distortions, in accordance with national circumstances, including by restructuring taxation and phasing out those harmful subsidies, where they exist, to reflect their environmental impacts, taking fully into account the specific needs and conditions of developing countries and minimizing the possible adverse impacts on their development in a manner that protects the poor and the affected communities

Climate action.

There is no country that is not experiencing the drastic effects of climate change. Greenhouse gas emissions are more than 50 percent higher than in 1990. Global warming is causing long-lasting changes to our climate system, which threatens irreversible consequences if we do not act.

The annual average economic losses from climate-related disasters are in the hundreds of billions of dollars. This is not to mention the human impact of geo-physical disasters, which are 91 percent climate-related, and which between 1998 and 2017 killed 1.3 million people, and left 4.4 billion injured. The goal aims to mobilize US$100 billion annually by 2020 to address the needs of developing countries to both adapt to climate change and invest in low-carbon development.

Supporting vulnerable regions will directly contribute not only to Goal 13 but also to the other SDGs. These actions must also go hand in hand with efforts to integrate disaster risk measures, sustainable natural resource management, and human security into national development strategies. It is still possible, with strong political will, increased investment, and using existing technology, to limit the increase in global mean temperature to two degrees Celsius above pre-industrial levels, aiming at 1.5 ° C, but this requires urgent and ambitious collective action.

As of 2017 humans are estimated to have caused approximately 1.0°C of global warming above pre-industrial levels.

Sea levels have risen by about 20 cm (8 inches) since 1880 and are projected to rise another 30–122 cm (1 to 4 feet) by 2100.

To limit warming to 1.5C, global net CO2 emissions must drop by 45% between 2010 and 2030, and reach net zero around 2050.

Climate pledges under The Paris Agreement cover only one third of the emissions reductions needed to keep the world below 2°C.

Bold climate action could trigger at least US$26 trillion in economic benefits by 2030.

The energy sector alone will create around 18 million more jobs by 2030, focused specifically on sustainable energy.

• Strengthen resilience and adaptive capacity to climate-related hazards and natural disasters in all countries
• Integrate climate change measures into national policies, strategies and planning
• Improve education, awareness-raising and human and institutional capacity on climate change mitigation, adaptation, impact reduction and early warning
• Implement the commitment undertaken by developed-country parties to the United Nations Framework Convention on Climate Change to a goal of mobilizing jointly $100 billion annually by 2020 from all sources to address the needs of developing countries in the context of meaningful mitigation actions and transparency on implementation and fully operationalize the Green Climate Fund through its capitalization as soon as possible
• Promote mechanisms for raising capacity for effective climate change-related planning and management in least developed countries and small island developing States, including focusing on women, youth and local and marginalized communities

Life below water.

The world’s oceans – their temperature, chemistry, currents and life – drive global systems that make the Earth habitable for humankind. How we manage this vital resource is essential for humanity as a whole, and to counterbalance the effects of climate change.

Over three billion people depend on marine and coastal biodiversity for their livelihoods. However, today we are seeing 30 percent of the world’s fish stocks overexploited, reaching below the level at which they can produce sustainable yields.

Oceans also absorb about 30 percent of the carbon dioxide produced by humans, and we are seeing a 26 percent rise in ocean acidification since the beginning of the industrial revolution. Marine pollution, an overwhelming majority of which comes from land-based sources, is reaching alarming levels, with an average of 13,000 pieces of plastic litter to be found on every square kilometre of ocean.

The SDGs aim to sustainably manage and protect marine and coastal ecosystems from pollution, as well as address the impacts of ocean acidification. Enhancing conservation and the sustainable use of ocean-based resources through international law will also help mitigate some of the challenges facing our oceans.

The ocean covers three quarters of the Earth’s surface and represents 99 percent of the living space on the planet by volume.

The ocean contains nearly 200,000 identified species, but actual numbers may lie in the millions.

As much as 40 percent of the ocean is heavily affected by pollution, depleted fisheries, loss of coastal habitats and other human activities.

The ocean absorbs about 30 percent of carbon dioxide produced by humans, buffering the impacts of global warming.

More than 3 billion people depend on marine and coastal biodiversity for their livelihoods.

The market value of marine and coastal resources and industries is estimated at US$3 trillion per year, about 5 percent of global GDP.

• By 2025, prevent and significantly reduce marine pollution of all kinds, in particular from land-based activities, including marine debris and nutrient pollution
• By 2020, sustainably manage and protect marine and coastal ecosystems to avoid significant adverse impacts, including by strengthening their resilience, and take action for their restoration in order to achieve healthy and productive oceans
• Minimize and address the impacts of ocean acidification, including through enhanced scientific cooperation at all levels
• By 2020, effectively regulate harvesting and end overfishing, illegal, unreported and unregulated fishing and destructive fishing practices and implement science-based management plans, in order to restore fish stocks in the shortest time feasible, at least to levels that can produce maximum sustainable yield as determined by their biological characteristics
• By 2020, conserve at least 10 per cent of coastal and marine areas, consistent with national and international law and based on the best available scientific information
• By 2020, prohibit certain forms of fisheries subsidies which contribute to overcapacity and overfishing, eliminate subsidies that contribute to illegal, unreported and unregulated fishing and refrain from introducing new such subsidies, recognizing that appropriate and effective special and differential treatment for developing and least developed countries should be an integral part of the World Trade Organization fisheries subsidies negotiation
• By 2030, increase the economic benefits to Small Island developing States and least developed countries from the sustainable use of marine resources, including through sustainable management of fisheries, aquaculture and tourism
• Increase scientific knowledge, develop research capacity and transfer marine technology, taking into account the Intergovernmental Oceanographic Commission Criteria and Guidelines on the Transfer of Marine Technology, in order to improve ocean health and to enhance the contribution of marine biodiversity to the development of developing countries, in particular small island developing States and least developed countries
• Provide access for small-scale artisanal fishers to marine resources and markets
• Enhance the conservation and sustainable use of oceans and their resources by implementing international law as reflected in UNCLOS, which provides the legal framework for the conservation and sustainable use of oceans and their resources, as recalled in paragraph 158 of The Future We Want

Life on land.

Human life depends on the earth as much as the ocean for our sustenance and livelihoods. Plant life provides 80 percent of the human diet, and we rely on agriculture as an important economic resources. Forests cover 30 percent of the Earth’s surface, provide vital habitats for millions of species, and important sources for clean air and water, as well as being crucial for combating climate change.

Every year, 13 million hectares of forests are lost, while the persistent degradation of drylands has led to the desertification of 3.6 billion hectares, disproportionately affecting poor communities.

While 15 percent of land is protected, biodiversity is still at risk. Nearly 7,000 species of animals and plants have been illegally traded. Wildlife trafficking not only erodes biodiversity, but creates insecurity, fuels conflict, and feeds corruption.

Urgent action must be taken to reduce the loss of natural habitats and biodiversity which are part of our common heritage and support global food and water security, climate change mitigation and adaptation, and peace and security.

Around 1.6 billion people depend on forests for their livelihoods.

Forests are home to more than 80 percent of all terrestrial species of animals, plants and insects.

2.6 billion people depend directly on agriculture for a living.

Nature-based climate solutions can contribute about a third of CO2 reductions by 2030.

The value of ecosystems to human livelihoods and well-being is $US125 trillion per year.v

Mountain regions provide 60-80 percent of the Earth's fresh water.

• By 2020, ensure the conservation, restoration and sustainable use of terrestrial and inland freshwater ecosystems and their services, in particular forests, wetlands, mountains and drylands, in line with obligations under international agreements
• By 2020, promote the implementation of sustainable management of all types of forests, halt deforestation, restore degraded forests and substantially increase afforestation and reforestation globally
• By 2030, combat desertification, restore degraded land and soil, including land affected by desertification, drought and floods, and strive to achieve a land degradation-neutral world
• By 2030, ensure the conservation of mountain ecosystems, including their biodiversity, in order to enhance their capacity to provide benefits that are essential for sustainable development
• Take urgent and significant action to reduce the degradation of natural habitats, halt the loss of biodiversity and, by 2020, protect and prevent the extinction of threatened species
• Promote fair and equitable sharing of the benefits arising from the utilization of genetic resources and promote appropriate access to such resources, as internationally agreed
• Take urgent action to end poaching and trafficking of protected species of flora and fauna and address both demand and supply of illegal wildlife products
• By 2020, introduce measures to prevent the introduction and significantly reduce the impact of invasive alien species on land and water ecosystems and control or eradicate the priority species
• By 2020, integrate ecosystem and biodiversity values into national and local planning, development processes, poverty reduction strategies and accounts
• Mobilize and significantly increase financial resources from all sources to conserve and sustainably use biodiversity and ecosystems
• Mobilize significant resources from all sources and at all levels to finance sustainable forest management and provide adequate incentives to developing countries to advance such management, including for conservation and reforestation
• Enhance global support for efforts to combat poaching and trafficking of protected species, including by increasing the capacity of local communities to pursue sustainable livelihood opportunities

In the line of fire

Peace, justice and strong institutions.

We cannot hope for sustainable development without peace, stability, human rights and effective governance, based on the rule of law. Yet our world is increasingly divided. Some regions enjoy peace, security and prosperity, while others fall into seemingly endless cycles of conflict and violence. This is not inevitable and must be addressed.

Armed violence and insecurity have a destructive impact on a country’s development, affecting economic growth, and often resulting in grievances that last for generations. Sexual violence, crime, exploitation and torture are also prevalent where there is conflict, or no rule of law, and countries must take measures to protect those who are most at risk

The SDGs aim to significantly reduce all forms of violence, and work with governments and communities to end conflict and insecurity. Promoting the rule of law and human rights are key to this process, as is reducing the flow of illicit arms and strengthening the participation of developing countries in the institutions of global governance.

By the end of 2017, 68.5 million people had been forcibly displaced as a result of persecution, conflict, violence or human rights violations.

There are at least 10 million stateless people who have been denied nationality and its related rights.

Corruption, bribery, theft and tax evasion cost developing countries US$1.26 trillion per year.

49 countries lack laws protecting women from domestic violence.

In 46 countries, women now hold more than 30 percent of seats in at least one chamber of national parliament.

1 billion people are legally ‘invisible’ because they cannot prove who they are. This includes an estimated 625 million children under 14 whose births were never registered.

• Significantly reduce all forms of violence and related death rates everywhere
• End abuse, exploitation, trafficking and all forms of violence against and torture of children
• Promote the rule of law at the national and international levels and ensure equal access to justice for all
• By 2030, significantly reduce illicit financial and arms flows, strengthen the recovery and return of stolen assets and combat all forms of organized crime
• Substantially reduce corruption and bribery in all their forms
• Develop effective, accountable and transparent institutions at all levels
• Ensure responsive, inclusive, participatory and representative decision-making at all levels
• Broaden and strengthen the participation of developing countries in the institutions of global governance
• By 2030, provide legal identity for all, including birth registration
• Ensure public access to information and protect fundamental freedoms, in accordance with national legislation and international agreements
• Strengthen relevant national institutions, including through international cooperation, for building capacity at all levels, in particular in developing countries, to prevent violence and combat terrorism and crime
• Promote and enforce non-discriminatory laws and policies for sustainable development

Partnerships for the goals.

The SDGs can only be realized with strong global partnerships and cooperation. Official Development Assistance remained steady but below target, at US$147 billion in 2017. While humanitarian crises brought on by conflict or natural disasters continue to demand more financial resources and aid. Many countries also require Official Development Assistance to encourage growth and trade.

The world is more interconnected than ever. Improving access to technology and knowledge is an important way to share ideas and foster innovation. Coordinating policies to help developing countries manage their debt, as well as promoting investment for the least developed, is vital for sustainable growth and development.

The goals aim to enhance North-South and South-South cooperation by supporting national plans to achieve all the targets. Promoting international trade, and helping developing countries increase their exports is all part of achieving a universal rules-based and equitable trading system that is fair and open and benefits all.

The UN Conference on Trade and Development (UNCTAD) says achieving SDGs will require US$5 trillion to $7 trillion in annual investment.

Total official development assistance reached US$147.2 billion in 2017.

In 2017, international remittances totaled US$613 billion; 76 percent of it went to developing countries.

In 2016, 6 countries met the international target to keep official development assistance at or above 0.7 percent of gross national income.

Sustainable and responsible investments represent high-potential sources of capital for SDGs. As of 2016, US$18.2 trillion was invested in this asset class.

The bond market for sustainable business is growing. In 2018 global green bonds reached US$155.5billion, up 78 percent from previous year.

• Strengthen domestic resource mobilization, including through international support to developing countries, to improve domestic capacity for tax and other revenue collection
• Developed countries to implement fully their official development assistance commitments, including the commitment by many developed countries to achieve the target of 0.7 per cent of ODA/GNI to developing countries and 0.15 to 0.20 per cent of ODA/GNI to least developed countries ODA providers are encouraged to consider setting a target to provide at least 0.20 per cent of ODA/GNI to least developed countries
• Mobilize additional financial resources for developing countries from multiple sources
• Assist developing countries in attaining long-term debt sustainability through coordinated policies aimed at fostering debt financing, debt relief and debt restructuring, as appropriate, and address the external debt of highly indebted poor countries to reduce debt distress
• Adopt and implement investment promotion regimes for least developed countries  
• Enhance North-South, South-South and triangular regional and international cooperation on and access to science, technology and innovation and enhance knowledge sharing on mutually agreed terms, including through improved coordination among existing mechanisms, in particular at the United Nations level, and through a global technology facilitation mechanism

• Fully operationalize the technology bank and science, technology and innovation capacity-building mechanism for least developed countries by 2017 and enhance the use of enabling technology, in particular information and communications technology  

Capacity building

• Enhance international support for implementing effective and targeted capacity-building in developing countries to support national plans to implement all the sustainable development goals, including through North-South, South-South and triangular cooperation  
• Promote a universal, rules-based, open, non-discriminatory and equitable multilateral trading system under the World Trade Organization, including through the conclusion of negotiations under its Doha Development Agenda
• Significantly increase the exports of developing countries, in particular with a view to doubling the least developed countries’ share of global exports by 2020
• Realize timely implementation of duty-free and quota-free market access on a lasting basis for all least developed countries, consistent with World Trade Organization decisions, including by ensuring that preferential rules of origin applicable to imports from least developed countries are transparent and simple, and contribute to facilitating market access  

Systemic issues

Policy and institutional coherence

• Enhance global macroeconomic stability, including through policy coordination and policy coherence
• Enhance policy coherence for sustainable development
• Respect each country’s policy space and leadership to establish and implement policies for poverty eradication and sustainable development

Essay On Sustainable Development

500 words essay on  sustainable development.

Sustainable development is basically an action plan which helps us to achieve sustainability in any activity which makes use of the resource. Moreover, it also demands immediate and intergenerational replication. Through essay on sustainable development, we will help you understand the concept and its advantages.

Through sustainable development, we formulate organising principles which help to sustain the limited resources essential to provide for the needs of our future generations. As a result, they will be able to lead a content life on the planet .

What is Sustainable Development?

The World Commission on Environment and Development popularized this concept in 1987. Their report defines the idea as a “development which meets the needs of the present without compromising the ability of future generations to meet their needs.”

In other words, they aimed to prevent the stripping the natural world of resources which the future generations will require. As we all know that usually, one particular need drives development. Consequently, the wider future impacts are not considered.

As a result, a lot of damage happens due to this type of approach. Thus, the longer we continue to pursue unsustainable development, the more severe will the consequences be. One of the most common is climate change which is being debated widely worldwide.

In fact, climate change is already wreaking havoc on our surroundings. So, the need of the hour is sustainable development. We must ask ourselves, must we leave a scorched planet with an ailing environment for our future generations?

In order to undo the mess created by us, we must follow sustainable development. This will help us promote a more social, environmental and economical thinking. Most importantly, it is not that difficult to attain this.

We must see that world as a system which connects space, and time. Basically, it helps you understand that water pollution in South Africa will ultimately impact water quality in India. Similarly, it is the case for other things as well.

COMING TOGETHER

17 rooms global flagship synthesis report.

file-pdf Coming together: Forging new paths to action for the Sustainable Development Goals

About 17 Rooms A partnership between the Center for Sustainable Development at Brookings and The Rockefeller Foundation, 17 Rooms is an experimental method for advancing the economic, social, and environmental priorities embedded in the world’s Sustainable Development Goals (SDGs). In 2021, more than 200 participants contributed to the global flagship process. See the list of participants here .

1. Seeking new paths to progress

The Sustainable Development Goals (SDGs) embody many of the world’s foremost priorities for cooperation. Protecting people. Promoting prosperity. Preserving the planet. Even before the COVID-19 pandemic took hold, the objectives embedded in the Goals were ambitious and wide-ranging—from the elimination of extreme deprivation to major reductions in inequality and switching course to safeguard nature. None of the 17 SDGs are optional. Major progress on each is essential for humanity to thrive. Moreover, for each individual Goal, the needed scale and scope of action requires new collaborative alliances across public, private, academic, civil society, and philanthropic sectors.

But the world is wracked by division. Too many existing institutions and processes meant to foster cooperation are not measuring up to the moment. Across communities, countries, and continents—there is widespread sentiment that things are stuck. The SDGs already called for new approaches to problem-solving. Setbacks triggered by COVID-19 have only amplified the need for a new path forward.

In this context, the Center for Sustainable Development at The Brookings Institution and The Rockefeller Foundation joined forces again in 2021 to convene the fourth annual 17 Rooms global flagship process. This evolving and experimental initiative aims to augment action, insight, and community across all 17 SDGs. The underlying motivation is to provide a neutral and creative space, alongside official processes, where leaders from different sectors and backgrounds can connect to collaborate and carry forward decisive next steps for the SDGs. Seventeen working groups or “Rooms”, one per SDG, came together to advance action within each Goal, while expanding opportunities for collaboration across Goals.

Emerging from the pandemic…we didn’t have the response that we needed to give us a good chance at recovery, and to put the SDGs back on track. This cannot just be about leaders and governments…we need to bring people into the room. The 131 U.N. offices…need to be inspired by this incredible energy that you have in these 17 Rooms…Because that is really where we need to implement in 9 years the sustainable development agenda. — Amina Mohammed, U.N. Deputy Secretary-General

A number of common themes, elements, and principles emerged across this year’s Rooms. The pandemic was never far from mind, including the catastrophic global inequities in access to COVID-19 vaccines. The working group focused on global inequality (Room 10 on SDG 10) did not shy away from calling out leadership failures among powerful countries. Too few have followed through on their own self-interest to cooperate with less powerful societies to bring the pandemic to an end.

Several other themes for action emerged too. First, digital public goods (DPGs) can be gamechangers for SDG progress. Building on successful recent cases like Togo (emphasized in Room 1 on SDG 1), more and more countries can develop digital cash transfer systems to respond to emergencies, preempt disasters, broaden inclusion, and reduce poverty. To realize the broader benefits of DPGs (a focus of Room 9 on SDG 9), a range of actors need to come together to support common protocols and communities of practice that strike a balance between the autonomy of locally-calibrated systems and interoperability across systems. Global outreach strategies are also needed to educate communities, policymakers, and investors on the value of DPGs, such as participatory digital health and data collection tools for pandemic preparedness and response (proposed by Room 3 on SDG 3).

Second, prompted by a summer of extreme weather events in the northern hemisphere, three Rooms (Rooms 13, 14, and 15) came to the view that focusing on the security and benefits that nature delivers to people where they live can be an effective strategy for catalyzing large-scale investments in ecosystems. Multiple environmentally-focused Rooms also emphasized the need for new financing frameworks to achieve necessary SDG outcomes (e.g., Room 13’s key pillars for a “breakthrough” in climate finance).

Third, multiple groups pursued practical avenues to shift global systems of power and agency to provide greater support for local leaders and communities, including to advance the needs of women and girls. For change to occur, international actors need to embrace existing local models and update legacy funding structures and mindsets (articulated by Room 11). Fiscal transparency is also essential to ensuring local disparities are squarely addressed (a Room 16 priority). Innovative conceptual approaches are needed too: one Room proposed a novel process tool to help local actors in any community negotiate areas of tension and align on areas of mutual benefit (Room 14’s “SDG narrative approach” for working seascapes).

Fourth, on themes of justice and equity, younger generations received attention as key partners for driving change across many fronts of sustainable development. This ranged from new approaches to promoting intergenerational learning teams (Room 4), networks for women leaders working for gender equality in faith contexts (Room 5), and communities of practice for a next generation of education, leadership, and innovation around the SDGs (Room 16).

It’s really nothing short of remarkable that the flagship process brings all of you together, such an extraordinary network of leaders from so many disciplines and sectors and organizations around the world…It’s also inspiring to know that the 17 Rooms approach now extends well beyond this flagship process… It’s invigorating to see 17 Rooms emerge as a more informal platform for bottom-up cooperation… The actions you take across the 17 Rooms are simply essential to carving a better path forward. — John R. Allen, President, The Brookings Institution

Fifth, recognizing that private capital and business need to play a crucial role in achieving the SDGs, several Rooms sought ways to make capitalism more accountable to the true societal cost (and value) of doing business. New tools, metrics, data systems, and reporting requirements can help drive better alignment between private sector incentives and SDG outcomes (Room 2, Room 8), especially when informed by more refined public debates (Room 12). In one instance (Room 17), this entails a pioneering multi-stakeholder collaboration to help steer market investors away from companies using forced labor.

Sixth, multiple Room deliberations called for reframing SDG ambitions. Sometimes this was conceptual, such as promoting a mindset shift around human waste management as a key input to tackling climate change (Room 6). In one other instance it was more technical, such as to update SDG energy access metrics to capture essential requirements for escaping poverty and supporting livelihoods (Room 7). These efforts reflected a desire for ongoing improvement in how the SDGs can promote human dignity, opportunity, and co-benefits across Goals.

This report captures key outcomes from this year’s 17 Rooms global flagship process, written from the perspective of the 17 Rooms secretariat. All of the Rooms have published their own short documents, in their own voice, as a companion series to this report. Section 2 provides a recap of the latest developments in the 17 Rooms methodologies. Section 3 summarizes each Room’s action agenda, alongside some opportunities for joint action that bubbled up across Rooms. Readers who are less interested in the methodological questions might wish to skip Section 2 and jump straight to Section 3. A brief concluding section provides a look-ahead to 2022.

2. Flagship 4.0: Shortening the path to action

Any 17 Rooms process is anchored in three design principles: all SDGs get a seat at the table; take a next step, not the perfect step; and engage in conversations, not presentations. (See 17 Rooms: A new approach to spurring action for the Sustainable Development Goals for more details.) Groups convene to discuss what “we,” in the Room, can do next. Participants are asked to “leave their institutional agendas at the door” to create space for new forms of collaboration.

In the 2021 flagship process, as in previous years, all Rooms were given a common assignment to identify one to three actionable priorities to advance over the coming 12-18 months (i.e., by the end of 2022) to improve some aspect of their Goal’s 2030 outcomes. In a concerted effort to confront COVID-19’s implications as the most gendered crisis in modern history, Rooms this year were also asked to articulate how their actionable priorities would help drive gains for women and girls (See Gender equality as a cross-cutting theme ).

Promoting action within Rooms

Within the flagship process, all Rooms work to a tight timetable, with only a limited number of meeting hours available to share perspectives, identify opportunities, and clarify next steps. Each Room had its first meeting in early June 2021, and then met at least once more before the end of July, when each Room shared its draft action plans to inform an all-Room summit on September 13th and 14th. By the beginning of October, Rooms finalized their action strategies for 2022.

Within each Room, the goal is to zero in on problems that are consequential and not already being solved elsewhere, ones where a neutral platform could help bring a critical mass of different people together to make gains. Rooms are encouraged to avoid “boiling the ocean”-type conversations that tackle every topic embedded within an SDG. Instead, Rooms are given freedom to “pick a swim lane within a swim lane” of their SDG, i.e., a slice of their Goal they deem ripe for action. In turn, Participants are encouraged to identify prospective actions that are “big enough to matter and small enough to get done.”

Early in 2021, the 17 Rooms secretariat began referencing a notion of “right-sizing” practical ingredients to promote cooperation for the SDGs. But later, it became clear this wasn’t the right word choice, since right-sizing often connotes scaling back ambition, and 17 Rooms seeks to raise ambitions for action. By the end of the 2021 flagship cycle, the term “action-sizing” was deemed a more fitting jargon for the 17 Rooms mindset—cultivating conditions to shorten the path toward ambitious cooperative actions.

In the spirit of action-sizing, one of this year’s core innovations was to frame a three-part menu for the types of cooperation that could help each group quickly align expectations around definitions of success. This typology included: “campfire” strategies for diverse stakeholders to forge a new consensus, “trial balloon” approaches for domain experts to vet and pilot actionable ideas, and “direct ascents” to mobilize collective execution on a shared priority (see “Room typologies” image below). The secretariat then worked with each Room Moderator team to align an appropriate mix of Room participants to match the task.

Promoting interaction between Rooms

Accelerating cooperation within Rooms frames only a first layer of the 17 Rooms logic. A next layer is to forge productive interactions between Rooms. In the first instance, convening 17 concurrent groups of energized and committed people generates natural positive peer effects. Progress in one Room can inform, motivate, and even guide best practices for other Rooms. Other forms of interactive opportunity also emerge. This year’s Rooms benefited from targeted (cross-Room) expert feedback on emerging Room actions, cross-Room learning on topics of common interest, and exploring joint Room strategies on shared action priorities.

Engaging expert feedback

Convening domain experts across all 17 Rooms creates enormous opportunities for Participants with relevant expert knowledge, resources, or perspectives to support other Rooms’ emerging actions. In the 2021 flagship, the most structured form of this occurred during the September virtual summit, in a curated “Room Charging Station” session. Participants visited other Rooms based on their individual interests and expertise, making suggestions to help each host Room succeed. In a post-summit survey, two-thirds of respondents deemed this session “essential.” According to one participant, the discussion provided “a great way to cross-pollinate,” while another described it as an opportunity “really to deepen [the] Room’s thinking as well as provoke new insights.”

Learning different perspectives on shared interests

Exchanging outlooks on common interests between Rooms can generate productive insights to inform action. As Room work streams began to take shape this year, the secretariat was able to spot common threads and opportunities to share perspectives between Rooms. For instance, Moderators from Room 16—focused on justice in COVID-19 recovery and relief funding—met with Moderators from Room 9—experts in digital public goods and digital public infrastructure—to discuss opportunities and challenges around establishing open and transparent community-level data sources disaggregated by gender and race. During the September summit, a more structured “Big Tents” session invited participants from all Rooms to explore bottlenecks and possibilities for progress across six emergent cross-cutting themes, ranging from digital public goods to environmental management, private sector metrics, gender equality, localizing power, and intergenerational collaboration. By sharing perspectives across Room domains, Participants had the opportunity to foster new insights through small-group discussions with other members of the 17 Rooms community.

Exploring joint action

The most intensive form of cross-Room connection is when Moderator teams start collaborating to co-design joint action. Within a time-constrained process like the 17 Rooms flagship, in which each Room faces an intensive challenge even to identify its own focused priorities, it is no small task to identify joint priorities across Rooms. Nonetheless, this year’s flagship saw some alignments bubbling up across Rooms, and facilitated opportunities for Room Moderator teams to explore collaboration directly. The upshot of these exchanges, including coordinated pursuit of advancing DPGs (Room 1 and Room 9) and a cross-Room proposal for a “Natural Security Initiative” (Room 15, Room 13, Room 14), are described in the next section below.

[17 Rooms is] needed now more than ever. We used to call this convening, and we realized that it’s not just convening […] By connecting folks, providing some resources, moving forward ideas …[we can] re-imagine what connected leaders can do around the world..to change the future outlook of human vulnerability and opportunity — Rajiv Shah, President, The Rockefeller Foundation

Gender equality as a cross-cutting theme

Within the 2021 17 Rooms global flagship process, each Room was asked to respond to the following common assignment:

What are 1 to 3 actionable priorities that your Room can identify and advance over the coming 12-18 months (i.e., by the end of 2022) to improve some component of your Goal’s 2030 outcomes? In light of COVID-19’s profound and widespread exacerbation of gender inequities, how can your Room’s actionable priorities help drive gains for women and girls?

The first question reflects a perennial design principle for 17 Rooms—focus on a next step, rather than a perfect step. The second question represents a concerted effort to elevate issues of gender inequality across all the Rooms in 2021.

A community survey at the outset of this year’s flagship process found that different Rooms had differing degrees of comfort in identifying gender-relevant priorities within their respective domains. Respecting this variation in starting points, the 17 Rooms initiative aimed to encourage each Room to take at least a concerted step forward in advancing gender equality within its chosen action domain.

Across Rooms, there was broad recognition of the enormity of the gender equality problem. Women and girls carry a disproportionate burden of adversities in the workplace, in education, in access to health care and DPGs, in personal security, and within the home. They are most vulnerable to the effects of climate change and related health, social, and economic volatility. Because of this, women and girls can secure particular benefits from new approaches to advancing SDG outcomes. For example, when technology provides remote learning opportunities in areas where travel is unsafe, when equitable digital cash transfer systems for emergency response are in place, when quality jobs with advancement opportunities are supported, and when clean fuel is used for cooking, women and girls can realize outsized benefits. Specific examples of Room insights and actions for gender equality include:

• Room 5 emphasized faith actors as agents for reshaping community norms for gender equality and supporting women leaders in faith contexts through cross-generational learning.
• Room 11 made clear that local communities and national governments need strong protocols to avoid elite capture, while supporting women leaders and women-led groups with financing.
• Room 13 noted a need for women and girls to be at the center of designing and benefiting from locally-led climate solutions, particularly for access to electricity and microfinance.
• Room 14 plans to ask the communities prototyping their “SDG narrative approach” to address the needs of women and girls in creating local stories for sustainable ecosystem management.
• Room 16 proposed ways to improve the collection of gender-disaggregated data at the community level—to identify equity gaps and help hold communities accountable for closing them.

During the September virtual summit, a cross-Room “Big Tents” session was devoted to advancing the needs of women and girls across the SDGs. Gender also featured as a strong theme during the summit’s final Room report out plenary, when keynote listener U.N. Deputy Secretary-General Amina Mohammed spoke powerfully to the importance of gender equality in her response to Rooms’ proposed action plans. Moving forward, the 17 Rooms initiative will keep prioritizing gender inequality and keep experimenting with ways to advance action-oriented priorities for gender equality across all SDGs.

I’ll do three C’s [for] what I found useful and engaging in [the 17 Rooms] process: Conversation—Sometimes we get exhausted with having conversations over and over again, but I found that in this group, bringing together the expertise, and the leadership of networks and on ideas, and having a room for just conversations has been so powerful; Connections—…there’s so much value in this process of connecting the dots between what already exists. How can we be dot connectors versus generators of new ideas? Catalyzation—How can we use our energy, our networks, our ideas, our experience, to catalyze what exists? — Blessing Omakwu, Deputy Director leading Goalkeepers, Bill & Melinda Gates Foundation

Joint action between Rooms

The Room actions listed above reflect a broad mix of ambitions for SDG policies and practice. Readers might also note substantive alignment among some of the Room agendas. Some of these are coincidental; others reflect more structured interactions. As one example, the natural overlap between Room 1’s approach to building a digital public good for social inclusion and Room 9’s focus on global-scale strategies for implementing digital public infrastructure led to multiple meetings between Room representatives to explore opportunities for joint action. Both Rooms agreed that in the immediate term, the most effective form of joint action would be to maintain an open line of knowledge sharing and connection, but to work in parallel on their respective strategies for advancing digital public infrastructure and digital public goods in 2022.

This year’s most structured cross-Room interaction took shape after Room 15 floated the idea of a “Natural Security Initiative” (NSI) to catalyze investment in nature to protect and benefit people where they live. They shared the proposal mid-stream with the co-Moderators of Room 13 (climate action) and Room 14 (oceans), who offered strong support, provided specific suggestions on next steps, and began to incorporate relevant work into their own Rooms. The NSI proposal is continuing to evolve, but it has begun with a concerted campaign to put people and equity at the center of global climate and biodiversity agendas in key high-level meetings in 2021 (e.g., the COP26 climate summit) and 2022 (e.g., the COP15 biodiversity summit and COP27 climate summit). Next steps are likely to include a sharper assessment of the geographic spread of required investments in nature, alongside a more fleshed out action plan for mobilizing relevant actors in 2022.

4. Looking to 2022

The 17 Rooms initiative aims to create a helpfully novel environment for problem solving across all 17 SDGs. The foremost ambition is to foster actions, insights, and interpersonal connections that improve the world’s sustainable development outcomes. All of the 2021 flagship Rooms deserve tremendous credit for generating such practical agendas within such limited time constraints. But the real measure of success will lie in the delivery of actions in 2022.

Importantly, few of the Room proposals were developed in isolation; most will advance and evolve through interactions with broader efforts underway elsewhere. Some Rooms (e.g., Room 11, Room 14) even extend explicit invitations for interested parties to get directly involved in their work. The Room action agendas are best interpreted as a dynamic springboard to further progress over the coming year, rather than a stationary landing pad.

In 2022, the 17 Rooms initiative will convene a fifth annual global flagship process, exploring possibilities for mixing virtual plus in-person convenings as the COVID-19 pandemic continues to evolve. While the virtual environment offers unique opportunities for efficient and inclusive global conversations, many members of the 17 Rooms community have conveyed a strong desire for physical convenings too.

The initiative will also continue to expand opportunities for decentralized SDG engagement through the “17 Rooms-X” community of practice. A growing diversity of communities, universities, regions, and national-scale bodies are exploring or already deploying 17 Rooms methodologies to connect and advance SDG actions in their own local contexts. The initiative is keen to see how its methods can support action, insight, and community for the SDGs at any scale of geography or network.

The 17 Rooms 2021 global flagship process convened an extraordinary mix of people pushing for large-scale global change. Their actions and insights show the types of progress that are possible when diverse communities come together. They can help to elevate, and hopefully inspire, decisive gains for sustainable development within every community around the world.

Sustainable Development Essay

500+ words essay on sustainable development.

Sustainable development is a central concept. It is a way of understanding the world and a method for solving global problems. The world population continues to rise rapidly. This increasing population needs basic essential things for their survival such as food, safe water, health care and shelter. This is where the concept of sustainable development comes into play. Sustainable development means meeting the needs of people without compromising the ability of future generations. In this essay on sustainable development, students will understand what sustainable development means and how we can practise sustainable development. Students can also access the list of CBSE essay topics to practise more essays.

What Does Sustainable Development Means?

The term “Sustainable Development” is defined as the development that meets the needs of the present generation without excessive use or abuse of natural resources so that they can be preserved for the next generation. There are three aims of sustainable development; first, the “Economic” which will help to attain balanced growth, second, the “Environment”, to preserve the ecosystem, and third, “Society” which will guarantee equal access to resources to all human beings. The key principle of sustainable development is the integration of environmental, social, and economic concerns into all aspects of decision-making.

Need for Sustainable Development?

There are several challenges that need attention in the arena of economic development and environmental depletion. Hence the idea of sustainable development is essential to address these issues. The need for sustainable development arises to curb or prevent environmental degradation. It will check the overexploitation and wastage of natural resources. It will help in finding alternative sources to regenerate renewable energy resources. It ensures a safer human life and a safer future for the next generation.

The COVID-19 pandemic has underscored the need to keep sustainable development at the very core of any development strategy. The pandemic has challenged the health infrastructure, adversely impacted livelihoods and exacerbated the inequality in the food and nutritional availability in the country. The immediate impact of the COVID-19 pandemic enabled the country to focus on sustainable development. In these difficult times, several reform measures have been taken by the Government. The State Governments also responded with several measures to support those affected by the pandemic through various initiatives and reliefs to fight against this pandemic.

How to Practise Sustainable Development?

The concept of sustainable development was born to address the growing and changing environmental challenges that our planet is facing. In order to do this, awareness must be spread among the people with the help of many campaigns and social activities. People can adopt a sustainable lifestyle by taking care of a few things such as switching off the lights when not in use; thus, they save electricity. People must use public transport as it will reduce greenhouse gas emissions and air pollution. They should save water and not waste food. They build a habit of using eco-friendly products. They should minimise waste generation by adapting to the principle of the 4 R’s which stands for refuse, reduce, reuse and recycle.

The concept of sustainable development must be included in the education system so that students get aware of it and start practising a sustainable lifestyle. With the help of empowered youth and local communities, many educational institutions should be opened to educate people about sustainable development. Thus, adapting to a sustainable lifestyle will help to save our Earth for future generations. Moreover, the Government of India has taken a number of initiatives on both mitigation and adaptation strategies with an emphasis on clean and efficient energy systems; resilient urban infrastructure; water conservation & preservation; safe, smart & sustainable green transportation networks; planned afforestation etc. The Government has also supported various sectors such as agriculture, forestry, coastal and low-lying systems and disaster management.

Today, global challenges such as poverty, inequality, and sustainability are at the core of the academic debate. This centrality has only increased since the transition from the Millennium Development Goals (MDGs) to the Sustainable Development Goals (SDGs), whose scope is to shift the world on to a path of resilience focused on promoting sustainable development. The main purpose of this paper is to develop a critical yet comprehensive scientometric analysis of the global academic production on the SDGs, from its approval in 2015 to 2020, conducted using Web of Science (WoS) database. Despite it being a relatively short period of time, scholars have published more than five thousand research papers in the matter, mainly in the fields of green and sustainable sciences. The attained results show how prolific authors and schools of knowledge are emerging, as key topics such as climate change, health and the burden diseases, or the global governance of these issues. However, deeper analyses also show how research gaps exist, persist and, in some cases, are widening. Greater understanding of this body of research is needed, to further strengthen evidence-based policies able to support the implementation of the 2030 Agenda and the achievement of the SDGs.

1. Introduction

1.1. from the millennium agenda to the 2030 agenda and the sustainable development goals (sdgs).

To track the origins of the 2030 Agenda for Sustainable Development, we must recall the Millennium Agenda, which was the first global plan focused on fighting poverty and its more extreme consequences [ 1 ]. Approved in 2000, its guiding principle was that northern countries should contribute to the development of southern states via Official Development Assistance (ODA) flows. The commitment was to reach 0.7% of donors’ gross domestic product [ 2 ] to reduce poverty by half by 2015. The relative failure to reach this goal and the consolidation of a discourse of segregation between northern and southern countries [ 3 ] opened the door to strong criticism of the Millennium Agenda. Therefore, as 2015 approached, there were widespread calls for a profound reformulation of the system [ 4 ].

The world in 2015 was very different from that in the early 2000s. Globalization had reached every corner of the world, generating development convergence between countries but increasing inequalities within countries [ 5 , 6 ]. Increasing interest in the environmental crisis and other global challenges, such as the relocation of work and migration flows, consolidated a new approach to development and the need of a more encompassed agenda [ 7 ]. This new agenda was conceived after an integrating process that involved representatives from governments, cooperation agencies, nongovernmental organisations, global business, and academia. The willingness of the 2030 Agenda to ‘leave no one behind’ relies on this unprecedented global commitment by the international community [ 8 ].

As a result of this process, in 2015, the United Nations General Assembly formally adopted the document “Transforming our World: the 2030 Agenda for Sustainable Development” [ 9 ], later known as the 2030 Agenda. This new global agenda is an all-comprising strategy that seeks to inform and orient public policies and private interventions in an extensive range of fields, from climate change to smart cities and from labour markets to birth mortality, among many others.

The declared scope of the Agenda is to shift the world on to a path of resilience focused on promoting sustainable development. To do so, the 2030 Agenda operates under the guidance of five principles, formally known as the ‘5 Ps’: people, planet, prosperity, peace, and partnerships [ 10 ]. With these pivotal concepts in mind, the Agenda has established a total of 17 Sustainable Development Goals (SDGs) and 169 specific targets to be pursued in a 15-year period, which reflects the scale and profound ambition of this new Agenda.

The SDGs do not only address what rich countries should do for the poor but rather what all countries should do together for the global well-being of this and future generations [ 4 ]. Thus, the SDGs cover a much broader range of issues than their predecessors, the Millennium Development Goals [ 11 ], and are intended to be universal on the guidance towards a new paradigm of sustainable development that the international community has been demanding since the 1992 Earth Summit [ 7 , 12 , 13 ].

Despite this potential, some criticise their vagueness, weakness, and unambitious character. Fukuda-Parr [ 14 ], see weaknesses on the simplicity of the SDGs, which can lead to a very narrow conception that reduces the integral concept of development. The issue of measurement is also problematic; for some researchers, the quantification of objectives not only reduces their complexity, but leads to them being carried out without considering the interdependencies between the objectives [ 12 , 13 ]. Other authors have identified difficulties associated with specifying some of the less visible, intangible aspects of their qualitative nature such as inclusive development and green growth [ 14 , 15 ]. Finally, Stafford-Smith et al. [ 16 ] state that their successful implementation also requires paying greater attention to the links across sectors, across societal actors and between and among low-, medium-, and high-income countries.

Despite these criticisms, the SDGs have undoubtedly become the framework for what the Brundtland report defined as our common future. Unlike conventional development agendas that focus on a restricted set of dimensions, the SDGs provide a holistic and multidimensional view of development [ 17 ]. In this line, Le Blanc [ 12 ] concludes that the SDGs constitute a system with a global perspective; because they consider the synergies and trade-offs between the different issues involved in sustainable development, and favour comprehensive thinking and policies.

1.2. Towards a categorization of the SDGs

There is an underlying lack of unanimity in the interpretation of the SDGs, which has given rise to alternative approaches that allow categorizing the issues involved in their achievement without losing sight of the integral vision of sustainable development [ 15 , 18 – 23 ]. However, such categorization of the SDGs makes it possible to approach them in a more holistic and integrated way, focusing on the issues that underlie sustainable development and on trying to elucidate their connections.

Among the many systematization proposals, and following the contributions of Hajer et al. [ 19 ], four connected perspectives can strengthen the universal relevance of the SDGs: a) ‘planetary boundaries’ that emphasize the urgency of addressing environmental concerns and calling on governments to take responsibility for global public goods; b) ‘The safe and just operating space’ to highlight the interconnectedness of social and environmental issues and their consequences for the redistribution of wealth and human well-being; c) ‘The energetic society’ that avoids the plundering of energy resources; and d) ‘green competition’ to stimulate innovation and new business practices that limit the consumption of resources.

Planetary boundaries demand international policies that coordinate efforts to avoid overexploitation of the planet [ 24 ]. Issues such as land degradation, deforestation, biodiversity loss and natural resource overexploitation exacerbate poverty and deepen inequalities [ 21 , 25 – 27 ]. These problems are further compounded by the increasing impacts of climate change with clear ramifications for natural systems and societies around the globe [ 21 , 28 ].

A safe and just operating space implies social inclusivity that ensures equity principles for sharing opportunities for development [ 15 , 29 ]. Furthermore, it requires providing equitable access to effective and high-quality preventive and curative care that reduces global health inequalities [ 30 , 31 ] and promotes human well-being. Studies such as that of Kruk et al. [ 32 ] analyse the reforms needed in health systems to reduce mortality and the systemic changes necessary for high-quality care.

An energetic society demands global, regional and local production and consumption patterns as demands for energy and natural resources continue to increase, providing challenges and opportunities for poverty reduction, economic development, sustainability and social cohesion [ 21 ].

Finally, green competition establishes limits to the consumption of resources, engaging both consumers and companies [ 22 ] and redefining the relationship between firms and their suppliers in the supply chain [ 33 ]. These limits must also be introduced into life in cities, fostering a new urban agenda [ 34 , 35 ]. Poor access to opportunities and services offered by urban centres (a function of distance, transport infrastructure and spatial distribution) is a major barrier to improved livelihoods and overall development [ 36 ].

The diversification of development issues has opened the door to a wide range of new realities that must be studied under the guiding principles of the SDGs, which involve scholars from all disciplines. As Saric et al. [ 37 ] claimed, a shift in academic research is needed to contribute to the achievement of the 2030 Agenda. The identification of critical pathways to success based on sound research is needed to inform a whole new set of policies and interventions aimed at rendering the SDGs both possible and feasible [ 38 ].

1.3. The relevance and impact of the SDGs on academic research

In the barely five years since their approval, the SDGs have proven the ability to mobilize the scientific community and offer an opportunity for researchers to bring interdisciplinary knowledge to facilitate the successful implementation of the 2030 Agenda [ 21 ]. The holistic vision of development considered in the SDGs has impacted very diverse fields of knowledge, such as land degradation processes [ 25 , 26 ], health [ 39 ], energy [ 40 ] and tourism [ 41 ], as well as a priori further disciplines such as earth observation [ 42 ] and neurosurgery [ 43 ]. However, more importantly, the inevitable interdependencies, conflicts and linkages between the different SDGs have also emerged in the analyses, highlighting ideas such as the need for systemic thinking that considers the spatial and temporal connectivity of the SDGs, which calls for multidisciplinary knowledge. According to Le Blanc [ 12 ], the identification of the systemic links between the objectives can be a valuable undertaking for the scientific community in the coming years and sustainable development.

Following this line, several scientific studies have tried to model the relationships between the SDGs in an attempt to clarify the synergies between the objectives, demonstrating their holistic nature [ 12 , 17 , 20 , 44 , 45 ]. This knowledge of interdependencies can bring out difficulties and risks, or conversely the drivers, in the implementation of the SDGs, which will facilitate their achievement [ 22 ]. In addition, it will allow proposing more transformative strategies to implement the SDG agenda, since it favours an overall vision that is opposed to the false illusion that global problems can be approached in isolation [ 19 ].

The lack of prioritisation of the SDGs has been one of the issues raised regarding their weakness, which should also be addressed by academics. For example, Gupta and Vegelin [ 15 ] analyse the dangers of inclusive development prioritising economic issues, relegating social or ecological inclusivity to the background, or the relational aspects of inclusivity that guarantee the existence of laws, policies and global rules that favour equal opportunities. Holden et al. [ 46 ] suggest that this prioritisation should be established according to three moral criteria: the satisfaction of human needs, social equity and respect for environmental limits. These principles must be based on ethical values that, according to Burford et al. [ 47 ], constitute the missing pillar of sustainability. In this way, the ethical imperatives of the SDGs and the values implicit in the discourses on sustainable development open up new possibilities for transdisciplinary research in the social sciences [ 46 , 47 ].

Research on SDG indicators has also been relevant in the academic world, as they offer an opportunity to replace conventional progress metrics such as gross domestic product (GDP) with other metrics more consistent with the current paradigm of development and social welfare that takes into account such aspects as gender equality, urban resilience and governance [ 20 , 48 ].

The study of the role of certain development agents, including companies, universities or supranational organisations, also opens up new areas of investigation for researchers. Some studies have shown the enthusiastic acceptance of the SDGs by companies [ 22 , 49 ]. For Bebbington and Unerman [ 50 ], the study of the role of organisations in achieving the SDGs should be centred around three issues: challenging definitions of entity boundaries to understand their full impacts, introducing new conceptual frameworks for analysis of the context within which organisations operate and re-examining the conceptual basis of justice, responsibility and accountability. On the other hand, the academic community has recognized that knowledge and education are two basic pillars for the transition towards sustainable development, so it may also be relevant to study the responsibility of higher education in achieving the SDGs [ 47 , 50 ]. Institutional sustainability and governance processes are issues that should be addressed in greater depth through research [ 47 ].

Finally, some authors have highlighted the role of information technologies (ICT) in achieving the SDGs [ 23 ] and their role in addressing inequality or vulnerability to processes such as financial exclusion [ 51 ], which opens up new avenues for research.

Despite this huge impact of the SDGs on academic research, to the best of our knowledge, an overall analysis of such an impact to understand its profoundness and capillarity is missing in the literature. To date, reviews have focused on the implementation of specific SDGs [ 52 – 61 ], on specific topics and collectives [ 62 – 70 ], on traditional fields of knowledge, now reconsidered in light of the SDGs [ 71 – 73 ] and on contributions from specific regions or countries [ 74 , 75 ]. By relying on scientometric techniques and data mining analyses, this paper collects and analyses the more than 5,000 papers published on the SDGs to pursue this challenging goal and fill this knowledge gap.

This article aims to provide a critical review of the scientific research on SDGs, a concept that has emerged based on multiple streams of thinking and has begun to be consolidated as of 2015. As such, global references on this topic are identified and highlighted to manage pre-existing knowledge to understand relationships among researchers and with SDG dimensions to enhance the presently dispersed understanding of this subject and its areas of further development. A scientometric meta-analysis of publications on SDGs is conducted to achieve this objective. Mainstream journals from the Web of Science (WoS) are used to identify current topics, the most involved journals, the most prolific authors, and the thematic areas around which the current academic SDG debate revolves.

Once Section 1 has revised on the related literature to accomplish the main objective, Section 2 presents the research methodology. Section 3 presents the main results obtained, and Section 4 critically discusses these results. The conclusion and the main limitations of the study are presented in Section 5.

2. Materials and methods

In methodological terms, this research applies scientometrics as a meta-analytical means to study the evolution of documented scientific knowledge on the Sustainable Development Goals [ 76 – 81 ], taking as a secondary source of information academic contributions (i.e. articles, reviews, editorials, etc.) indexed in the Web of Science (WoS). To ensure that only peer-reviewed contributions authored by individual researchers are retrieved and that such publications have a worldwide prestige assessment, all of them should be published on journals indexed in the Journal Citation Report (JCR), either as part of the Sciences Citation Index Expanded or the Social Sciences Citation Index [ 82 – 84 ].

Following the recommendations of previous studies [ 85 ], it was decided to apply the next search vector from 2015 to 2020 to achieve the research objectives TS = (Sustainable NEAR/0 Development NEAR/0 Goals), which allows the extraction of data with 67 fields for each article registered in WoS.

As the first step, to give meaning to subsequent analyses, we tested the presence of exponential growth in the production of documented knowledge that allows a continuous renewal of knowledge [ 76 , 86 ].

As a second action, given the recent nature of the subject studied, it is of interest to map the playing field [ 87 ] using VOSviewer software version 1.6.16 [ 88 ], to know which topics are most addressed in the matter of SDGs. This analysis seeks an approach, both through the concentration of Keyword Plus® [ 89 ] and by analysing the references used as input in the production of knowledge, which can be treated as cocitations, coupling-citations and cross-citations [ 90 ], using the h-index, in citation terms, as discriminant criteria in the selection of articles [ 91 – 93 ]. This methodology will allow us to establish production, impact and relationship metrics [ 80 , 85 , 87 , 94 , 95 ].

Finally, it is of interest to explore the possible concentrations that may arise. Using Lotka’s Law, we estimated the possible prolific authors and their areas of work in SDGs, and using Bradford’s Law, we conducted a search of a possible adjustment to a geometric series of the concentration zones of journals and therefore a potential nucleus where a profuse discussion on SDGs is taking place [ 96 – 100 ].

3.1. Configuration of the academic production on SDGs

The results present a total of 5,281 articles for a period of six years (2015–2020) in 1,135 journals, with over 60% of these documents published in the last two years. The total of articles is distributed among authors affiliated with 7,418 organisations from 181 countries/regions, giving thematic coverage to 183 categories of the Journal Citation Report-Web of Science (JCR-WoS). Table 1 shows the distribution among the top ten JCR-WoS categories, highlighting the prevalence of journals indexed in green and environmental sciences and, thus, in the Science Index-Expanded.

3.2. Existence of research critical mass

Fig 1 shows the regression model for the period 2015–2020, the last year with complete records consolidated in the Web of Science. The results obtained show significant growth in the number of studies on SDGs, with an R 2 adjustment greater than 96%. The exponential nature of the model shows that a ‘critical mass’ is consolidating around the research on this topic, as proposed by the Law of Exponential Growth of Science over Time [ 76 ], which in some way gives meaning to this research and to obtaining derived results.

3.3. Establishment of concentrations

In accordance with Lotka’s Law, 22,336 authors were identified of the 5,281 articles under study. From this author set, 136 (≈sqrt (22,336)) are considered prolific authors with a contribution to nine or more works. However, a second restriction, even more demanding, is to identify those prolific authors who are also prolific in contemporary terms. Although SDG studies are recent, the growth production rates are extremely high. As previously shown, for the period 2015–2020, 64% of the publications are concentrated between 2019–2020. Based on this second restriction, for 3,400 articles of the 5,281 articles published in 2019 and 2020, and a total of 15,120 authors, only eight prolific authors manage to sustain a publication number that equals or exceeds nine articles. These authors are listed and characterized in Table 2 .

https://doi.org/10.1371/journal.pone.0265409.t002

The analysis shown in Table 2 highlights the University of Washington’s participation in health issues with Murray and Hay (coauthors of eight articles in the period 2019–2020), who are also important in the area of health for the prolific authors Yaya and Bhutta. The environmental SDGs mark a strong presence with Abhilash, Leal-Filho and Kalin. The affiliation of Abhilsash (Banaras Hindu University) is novel, as it is not part of the classic world core in knowledge production that is largely concentrated in the United States and Europe. It is worth noting that other prolific authors belong to nonmainstream knowledge production world areas, such as Russia or Pakistan. Professor Alola also deserves mention; not only is he the only contemporary prolific author producing in the area of economics, but he is also producing knowledge in Turkey.

In the same way, at the journal level, the potential establishment of concentration areas and determination of a deep discussion nucleus are analysed using Bradford’s law.

With a percentage error of 0.6%, between the total journal number and the total journal number estimated by the Bradford series, the database shows a core of 18 journals (2%) where one in three articles published are concentrated (see Table 3 ).

https://doi.org/10.1371/journal.pone.0265409.t003

Regarding the number of contributions by journal, Sustainability has the largest number of studies on SDGs, in which 689 (13%) of the 5,281 articles studied are concentrated. The Journal of Cleaner Production, indexed to WoS categories related to Environmental SDGs, is the second most prominent journal, with 2.7% participation of the articles (147). Both journals are followed by the multidisciplinary journal Plos One, with 2.2% of the total dataset. In terms of impact factor, the 60 points of the health journal The Lancet are superlative in the whole, which in the other cases ranges between 2.000 and 7.246. As shown in Table 4 , we have developed a “Prominence ranking” by weighting article production by impact factor. This metric shows The Lancet, with only 40 articles on SDGs, as the most relevant journal, followed by Sustainability, which becomes relevant due to the high number of publications (689) despite an impact factor of 2.576. These journals are followed by the Journal of Cleaner Production with 147 articles and an impact factor of 7.246.

https://doi.org/10.1371/journal.pone.0265409.t004

3.4. Thematic coverage

Concerning the thematic coverage, Fig 2A and 2B show a diversity of 7,003 Keyword Plus® (KWP), consistently connected to a total of 7,141 KWP assigned by Clarivate as metadata to the set of 5,281 articles studied, which presents a strong concentration in a small number of terms (red colour in the heat map generated with VOSviewer version 1.6.16).

a) Keywords Plus® heatmap and b) heat map zoom to highlight the highest concentration words, data source WoS, 2020.

https://doi.org/10.1371/journal.pone.0265409.g002

Based on this result, a concentration sphere with 85 KWP (= sqrt (7,141)) is established according to Zipf’s Law, which is presented in 50 or more articles out of the total of 5,281. Moreover, a central concentration sphere of 9 KWPs (= sqrt (85)) can be found, with keywords present in a range of 178 to 346 articles out of a total of 5,281. These nine pivotal keywords are all connected in terms of co-occurrence (associated by Clarivate two or more to the same article) and within papers with an average number of citations in WoS that vary from 9.27 to 16.69, as shown in Table 5 . The nine most prominent key words in relation to the study of the SDGs are health, climate change, management, impact, challenges, governance, systems, policy and framework. These terms already suggest some of the themes around which the debate and research in this area revolves.

https://doi.org/10.1371/journal.pone.0265409.t005

The prominence of these keywords is obtained by combining the level of occurrence and average citations (see Table 5 ): on the one hand, the occurrence or number of articles with which the KWP is associated (e.g., Management, 346) and, on the other hand, the average citations presented by the articles associated with these words (e.g., Framework. 9.27). The final score (prominence) mixes both concepts, given the product of the occurrences and the average citations of each KWP in proportion to the mean values (e.g., (330 * 16.69)/(246 * 11.96) = 1.9).

3.5. Relations within the academic contributions

The coupling-citation analysis using VOSviewer identifies the 5,281 articles under study, of which only those found in the h-index as a whole have been considered (the h-index in the database is 81, as there are 81 articles cited 81 or more times). The bibliographic coupling analysis found consistent connections in only 73 of these articles, gathered in seven clusters. Such clusters and unconnected articles are represented in Fig 3 .

Data source WoS. 2020.

https://doi.org/10.1371/journal.pone.0265409.g003

In simple terms, discrimination belonging to one cluster or another depends on the total link number that an article has with the other 80 articles based on the use of the common references. Table 6 specifies the articles belonging to the same publication cluster in relation to Fig 3 .

https://doi.org/10.1371/journal.pone.0265409.t006

Bibliographic coupling analysis can also be used to link the seven clusters that use common references with the field document title (TI), publication name (SO), Keyword Plus-KWP (ID), and research areas (SC). This allows the identification of the main topics of each cluster. As shown in Table 7 , cluster 1 (red) concerns environmental and public affairs; cluster 2 (green), health; cluster 3 (blue), economics; cluster 4 (yellow), health–the burden of disease; cluster 5 (violet), economics–Kuznets curve; cluster 6 (light blue), energy; and cluster 7 (orange), soil—land.

https://doi.org/10.1371/journal.pone.0265409.t007

3.6. Outstanding contributions in the field

The cocitation analysis identified a total of 232,081 references cited by the 5,281 articles under study. It suggests taking as references to review those that present 44 or more occurrences in the database (232,081/5,281). This method results in 34 articles that have been used as main inputs for the scientific production under analysis, cited between 44 and 504 times. A result worth highlighting is that one in three of these documents corresponds to reports from international organisations, such as the United Nations (UN), United Nations Educational, Scientific and Cultural Organization (UNESCO), United Nations International Children’s Emergency Fund (UNICEF), United Nations Fund for Population Activities (UNFPA), World Bank Group (WB) or World Health Organization (WHO). However, it is also possible to identify 21 peer-reviewed scientific contributions. These papers are identified in detail in Table 8 .

https://doi.org/10.1371/journal.pone.0265409.t008

The cocitation analysis yields the degree of relationship of these 21 most cited research articles. It is how such references have been used simultaneously in the same article. Fig 4 displays this information (to help readers, it has also been included in Table 8 , centrality in 21 column).

https://doi.org/10.1371/journal.pone.0265409.g004

According to the relationship level in the most cited article’s selection, the graph ( Fig 3 ) has been clustered in three colours: cluster 1 in red colour groups the highest articles proportion (9) published between 2013 and 2017 in 7 journals. These journals present an impact factor (IF) quite heterogeneous, with values ranging from 2.576 (Sustainability) to 60.39 (Lancet) and indexed in one or more of the following WoS categories: Environmental Sciences (4 journals), Green & Sustainable Science & Technology (4), Environmental Studies (2), Development Studies (1), Medicine, General & Internal (1), Multidisciplinary Sciences (1) and Regional & Urban Planning (1). Three of these articles are cited 130–150 times in the 5,281-article dataset and, at the same time, show a connection centrality of 95–100% with the other 20 articles in the graph, implying a high level of cocitation. The other two clusters group six articles each. The articles of cluster 2 (green colour) are included in a widespread WoS category set: Environmental Sciences (3 journals), Geosciences, Multidisciplinary (2), Ecology (1), Economics (1), Energy & Fuels (1), Environmental Studies (1), Green & Sustainable Science & Technology (1), Materials Science, Multidisciplinary (1), Meteorology & Atmospheric Sciences (1) and Multidisciplinary Sciences (1). The research of Nilsson [ 101 ] was used as a reference in 176 of the 5,281 articles under study, showing a centrality of 100%. This great connection level is also featured in another less cited article [ 17 ] published in Earth’s Future. Finally, cluster 3 (blue) highlights six articles concentrated in three highly cited journals in the WoS categories: Medicine, General & Internal (Lancet) and Multidisciplinary Sciences (Nature and Science), whose IFs range from 41.9 to 60.4. In general, they are articles less connected (cocited) to the set of 21, with centralities of 30–90%. Two of these articles were referenced 140 times or more, although one was published in 2009. Thus, cluster 3 concentrates the references mainly in journals on environmental issues with scientific-technological orientation, as well as classic and high-impact WoS journals (The Lancet, Nature and Science). It is worth noting that some of these top journals may not be listed in Table 4 as they are not included in the Bradford’s nucleus, due to their comparatively low number of contributions published.

Finally, continuing with the thematic study, a cross-citation analysis was developed. Considering only the 81 articles that are part of the h-index of the total set of 5,821 articles under study, the citations that are presented among this elite article set are explored using VosViewer. The cross-citation analysis detects existing relationships between 37 of these 81 articles. Once the directionality of the citations has been analysed, a directed temporal graph is generated using Pajek 64 version 5.09, which is presented in Fig 5 .

https://doi.org/10.1371/journal.pone.0265409.g005

Fig 5 shows how these 37 highly cited articles are related to each other (the number after the name is the publication year), considering that some of these articles are cited as references in other articles in this set. The relationships between the articles in Fig 5 are complex and should be understood under a temporal sequence logic in the citation between two articles. However, some trends can be highlighted.

On the one hand, some contributions stand out for their centrality. Lim et al. [ 102 ] is connected with eight of the 37 articles (21.6%) on citing relationships, as is Fullman et al. [ 27 ], which relates to seven of the 37 articles (18.9%). Both authors researched health issues and are also coauthors of nine articles of the dataset under study. On the other hand, according to the SDG segmentation proposed, Hajer et al. [ 19 ] and Le Blanc [ 12 ] are recognized as seminal articles in social SDGs, since they contribute to the production of other subsequent articles in the set of 37. On the other hand, in health matters, seminal articles are Norheim et al. [ 103 ] and You et al. [ 104 ], two articles published in The Lancet whose citations also contribute to the production of the set introduced as Fig 5 .

4. Discussion

The main purpose of this paper was to develop a critical and comprehensive scientometric analysis of the global academic literature on the SDGs from 2015 to 2020, conducted using the WoS database. The attained results have made it possible to comprehend and communicate to the scientific community the current state of the debate on the SDGs, thus offering insights for future lines of research.

To achieve the objectives, the present study analysed a broad spectrum of 5,281 articles published in 1,135 WoS journals. A first aspect that is striking is the great diversity of topics addressed in these studies, which reflects the multidimensionality of the SDGs. Despite this, more than half of the articles are concentrated in two JCR-WoS categories (Environmental Sciences and Green Sustainable Science Technology), a percentage that exceeds 80% if the categories Environmental Studies and Public Environmental Occupational Health are added. Thus, on the one hand, the size of the body of literature and the broad spectrum of topics more than covers the four perspectives of analysis that are relevant in research on the SDGs, according to Hajer et al. [ 19 ]: planetary boundaries, the safe and just operating space, the energetic society and, last, green competition. However, on the other hand, results also highlight a strong focus on the environmental aspects of the SDGs, which undoubtedly concentrate the most contributions.

The Sustainable Development Goals constitute an area of research that has experienced exponential scientific growth, a tendency already suggested by previous studies [ 81 , 105 ], thus complying with the fundamental principles of Price’s law [ 76 ], which suggests the need for this exponential growth to manifest a continuous renewal of knowledge on the subject under study. The results of this study highlight a significant increase in the number of articles published in the last two years, given that six out of ten articles were published in 2019 or 2020. This tendency confirms how the SDGs continue to arouse great interest in the scientific community and that the debate on the interpretation of sustainable development is still open and very present in academia.

The variety of knowledge areas from which science can approach the SDGs demonstrates the different avenues that exist to address different research questions and their multidimensional nature, as anticipated by Pradhan et al. [ 17 ], a dispersion not far from the traditional fields of knowledge or the conventional dimensions of sustainability. Investigating the reasons for this dispersion in academic research on the SDGs may be a topic of great interest, as anticipated by Burford et al. [ 47 ] and Le Blanc [ 12 ], since understanding the phenomenon of development can only be achieved if the main challenges, both current and future, can be viewed holistically and comprehensively. Along these lines, Imaz and Eizagirre [ 106 ] state that the complexity of the study of the SDGs is undoubtedly marked by their aspiration for universality, by their broad scope encompassing the three basic pillars of sustainable development (economic development, environmental sustainability and social inclusion) and by their desire for integration, motivated by the complexity of the challenges and by the countless interlinkages and interdependencies.

This natural multidimensionality of the SDGs calls for strong cooperation and collaboration between researchers, universities, and countries. In this sense, the scientometric analysis provides good news, as more than a hundred prolific authors (defined as those authors who have published nine or more articles on this topic) have been identified, although these are reduced to eight in contemporary terms (2019 or 2020). This select group of eight authors who lead research and publishing on the SDGs (sometimes with dual or triple affiliations) produce knowledge for universities and research centres both in the global north and the global south: Canada, the U.S., the UK, Germany, Pakistan, Turkey, India, Benin, Russia and Cyprus. The protagonist role played by research institutes in countries in the north has already been acknowledged by previous studies [ 81 , 105 ]. However, the emergence of top scholars producing academic knowledge from developing countries is a more recent tendency, which underscores the pertinence of this analysis.

A closer look at the academic and research curricula of these authors leads to the conclusion that the study of the SDGs does not constitute a final field of research at present. These researchers come from very heterogeneous disciplines, so their approach to the SDGs is also multidisciplinary. To illustrate it with an example, the most cited article by Professor Abhilash of Banaras Hindu University (the most published contemporary prolific author along with Christopher Murray of the University of Washington), with 363 WoS citations in February 2021 alone, is on the use and application of pesticides in India.

In more concrete terms, following Wu et al.’s [ 23 ] classification as a frame of reference, the eight most prolific contemporary authors approach the SDG research problem from two main domains, one of an environmental nature (Abhilash, Leal-Filho, Alola and Kalin) and the other related to health (Murray, Yaya, Bhutta, and Hay). The most common journals where these authors publish on environmental issues are the Journal of Cleaner Production, Higher Education, Water and Science of the Total Environment. Health researchers, on the other hand, tend to publish mainly in the journals of the BMC group, The Lancet and Nature.

This wide diversity of academic fora can be clarified with the application of Bradford’s laws, which identified a core of 18 journals that bring together the debates and academic discussions about the SDGs. It is worth noting that the 18 journals that form the core are distributed in 16 different thematic areas or WoS categories: Development Studies; Ecology; Economics; Education & Educational Research; Engineering, Environmental; Environmental Sciences; Environmental Studies; Green & Sustainable Science & Technology; Hospitality, Leisure, Sport & Tourism; International Relations; Medicine, General & Internal; Multidisciplinary Sciences; Public, Environmental & Occupational Health; Regional & Urban Planning; and Water Resources. On the one hand, this wide dispersion in terms of areas of knowledge suggests that research on the SDGs can be studied from different approaches and disciplines, which opens up a wide range of possibilities for researchers from different branches of scientific knowledge, as well as an opportunity for multidisciplinary collaborations. On the other hand, this heterogeneity might also hinder the communication and dissemination of learning from one field to another. The cross-citation analysis provided in Fig 5 suggests this possibility, as seminal works are related to thematic disciplines more than to the seminal contributions identified in Table 8 .

In this sense, it is interesting to analyse the top-cited articles in the database, as they provide a clear picture of the field of knowledge. One-third of these contributions are provided by international institutions, such as the United Nations Development Program or the World Bank, which provide analyses of a normative nature. This prevalence reflects some weaknesses in the academic basis of the analysis of the SDGs as a whole from a scientific approach, an idea reinforced when the most cited papers are analysed. In fact, only six papers have reached more than 100 citations by contributions included in the database [ 4 , 12 , 24 , 29 , 101 , 107 ]. Not only were these papers largely published before the approval of the SDGs themselves, but half of them are editorial material, inviting contributions but are not evidence-based research papers. Highlighting the nature of the most cited contributions does not diminish their value but does speak to the normative approach that underlies the analysis of the SDGs when addressed not individually but as an overall field of research.

Regarding topics and themes of interest, the scientometric analysis carried out in this research identified a strong concentration around a small number of terms, as represented in a heat map ( Fig 2A and 2B ). All these topics constitute a potential source of inspiration for future research on the subject.

Through an analysis of the main keywords, it can be seen that the studies focused on the traditional areas of health and climate change. However, these keywords also provide new elements for discussion, as they uncover some other areas of study that have been highlighted by the literature. First, the appearance of the term Management as one of the main keywords reveals the importance that researchers give to the role of business in achieving the SDGs, as already suggested by Scheyvens et al. [ 49 ] and Spangenber [ 22 ]. Second, the need to address new governance processes and to seek global solutions, as suggested by authors such as Sachs [ 4 ], underscore the keywords Governance, Policy and Framework, all aspects deemed crucial for the achievement of the SDGs and the 2030 Agenda [ 108 ]. Finally, other keywords such as Impact, Challenges or Systems are a clear example of the complexity and interdependencies that exist in research on the SDGs, considered an essential aspect by Griggs et al. [ 13 ] or Le Blanc [ 12 ]. The attained results highlight some of the connections between different domains of sustainable development by identifying categories and themes that are highly related in the groupings that emerge from the bibliographic coupling analysis.

In general terms, the holistic vision of development embodied by the SDGs has drawn the attention of very different disciplines, fields and areas of scientific knowledge. However, seven major areas of research have emerged: environmental and public affairs, health, economics, health-burden of disease, economics-Kuznets curve, energy and soil-land. These areas are not far removed from the current paradigm of sustainable development, where poverty or inequality are problems that are not exclusive to developing countries [ 5 , 6 ]. Thus, emerging issues that mainly affect first world countries, including urban planning, the impact of activities such as hospitality, sport or tourism, or education for development, are starting to stand out with increasing intensity, which continues to open new avenues for future research.

In short, the results of the scientometric analysis have provided a systematized overview of the research conducted in relation to the SDGs since the approval of the 2030 Agenda. Among other things, the critical analysis has identified the main trends with respect to the number of publications, the most relevant journals, the most prolific authors, institutions and countries, and the collaborative networks between authors and the research areas at the epicentre of the debate on the SDGs. As Olawumi and Chan [ 105 ] already acknowledged, the power research networks applied to the study of the SDGs offer valuable insights and in-depth understandings not only of key scholars and institutions but also about the state of research fields, emerging trends and salient topics.

Consequently, the results of this work contribute to the systematic analysis of scientific research on the SDGs, which can be of great interest for decision-making at the governmental level (e.g., which research to fund and which not to fund), at the corporate level and at the level of research centres, both public and private. Furthermore, the scientometric analysis carried out may provide clues for academics regarding future lines of research and topics of interest where the debate on the SDGs is currently situated.

5. Conclusions, limitations and future research lines

As could not be otherwise, all research in the field of social sciences has a series of limitations that must be clearly and transparently explained. The two most relevant in this study are the following.

First, although the study of the SDGs is a recent object of research, the rate of publication is growing exponentially, such that scientific knowledge is renewed practically in its entirety every two years. The only articles that escape this scientometric obsolescence are those with a high number of citations (h-index). This circumstance generates a temporal limitation in terms of the conclusions obtained in the present investigation, conclusions that should be revised periodically until the growth of publications stabilizes by adopting a logistic form, as recommended by Sun and Lin [ 109 ].

Second, the articles used as the basis for this research were restricted to those published in the JCR-WoS. This decision was made for two main reasons. On the one hand, the limitation was to eliminate potential distortions that could occur as a result of the constant growth of journals that are incorporated annually into other databases, such as ESCI-WoS (Emerging Sources Citation Index). On the other hand, it is impossible to compare impact indices if integrating other databases such as Scopus.

We are aware of these limitations, which for developing a more selective analysis imply assuming the cost of less coverage in exchange.

Regarding future lines of research, the analysis highlights how the study of the SDGs is failing to balance their economic, social and sustainability components, as it still maintains an overall focus on environmental studies.

This suggests the urgency of increasing studies on social SDGs, key topics on the 2030 Agenda including equity (SDGs 4, 5 and 10), social development (SDGs 11 and 16) and governance (SDG 17). These topics are part of the public discourse and currently a source of social pressure in many latitudes, but they are still research areas that are necessary to deepen.

Economic sustainability studies are more present, but highly concentrated, in health economics, as previously acknowledged by Meschede [ 81 ]. Academic research on the SDGs against poverty (SDG 1) and hunger (SDG 2) has not achieved such a prominent place as health. Even less so, the economics of technological development (SDGs 8 and 9), which are recognized as crucial for economic development.

Finally, the environmental SDGs do not achieve a balance among themselves either. Academic research has prioritized action for climate (SDG 13) and industrial and human consumption, mainly water (SDG 6) and energy (SDG 7). New research should be developed in the area of land (SDG 15), life under the sea (SDG 14) and sustainable production (SDG 12).

Sustainable Development Goal (SDG) 11 is about making “cities and human settlements inclusive, safe, resilient, and sustainable.” It is one of the 17 SDGs in the 2030 Agenda for Sustainable Development .

In 2015, the United Nations (UN) adopted the 2030 Agenda for Sustainable Development , a plan to promote peace and sustainable growth worldwide. One of the goals within the plan is SDG 11, which addresses urban development. The goal says cities should ensure access to safe and affordable housing, public transportation, and public green spaces. It states that cities should be resilient to natural disasters and protect those in vulnerable situations while also minimizing economic loss.

One sustainability target that is often overlooked is social sustainability and civic engagement . This includes actions individuals can take, like voting for measures that increase sustainability in their own city or for politicians who support these measures. People can also attend their city’s public forums to give feedback on sustainability initiatives. Taken as a whole, SDG 11 is a comprehensive and complex goal: creating sustainable cities that can withstand both climate change and unprecedented growth.

The Agenda for Sustainable Development , and the goals contained within it, are important because nations are facing new challenges as their cities grow in size and in population. The 2019 progress review of SDG 11 stated: “Globally, urban areas are expanding at a faster rate than their populations. Between 2000 and 2014, areas occupied by cities grew 1.28 times faster than their populations.” This means that cities are sprawling and becoming less dense. This leaves some urban residents without access to necessary infrastructure , like public transportation.

Environmental concerns are heightened in areas of urban growth as well. Air quality is worse in urban areas, and cities account for 70 percent of greenhouse gas emissions . Cities are also extremely vulnerable to the impacts of climate change , as a high number of urban areas lie along coastlines, which are prone to climate change –related natural disasters.

Many cities have already implemented sustainability efforts to meet SDG 11. Cities such as London, England, and New York City, New York, have passed legislation for congestion pricing to reduce air pollution. Congestion pricing is used to discourage people from driving by charging drivers higher tolls if they travel during rush hour or in certain high-traffic areas. Drivers of electric cars are sometimes allowed to travel for free in order to encourage environmentally conscious travel. Individuals can participate in this effort by choosing an electric car as their next vehicle or opting to walk or bike more frequently.

Though SDG 11 is primarily focused on government action, the initiatives need community buy-in from individual citizens as well as community leaders. For example, individuals can take actions such as fixing up their local parks, creating rooftop gardens, or participating in community composting programs to improve the quality of greenspaces and create additional ones in new spots. People can make small steps in their own neighborhoods to support sustainable cities on a world-wide level.

Goal 2: Zero Hunger

Goal 2 is about creating a world free of hunger by 2030.The global issue of hunger and food insecurity has shown an alarming increase since 2015, a trend exacerbated by a combination of factors including the pandemic, conflict, climate change, and deepening inequalities.

By 2022, approximately 735 million people – or 9.2% of the world’s population – found themselves in a state of chronic hunger – a staggering rise compared to 2019. This data underscores the severity of the situation, revealing a growing crisis.

In addition, an estimated 2.4 billion people faced moderate to severe food insecurity in 2022. This classification signifies their lack of access to sufficient nourishment. This number escalated by an alarming 391 million people compared to 2019.

The persistent surge in hunger and food insecurity, fueled by a complex interplay of factors, demands immediate attention and coordinated global efforts to alleviate this critical humanitarian challenge.

Extreme hunger and malnutrition remains a barrier to sustainable development and creates a trap from which people cannot easily escape. Hunger and malnutrition mean less productive individuals, who are more prone to disease and thus often unable to earn more and improve their livelihoods.

2 billion people in the world do not have reg- ular access to safe, nutritious and sufficient food. In 2022, 148 million children had stunted growth and 45 million children under the age of 5 were affected by wasting.

How many people are hungry?

It is projected that more than 600 million people worldwide will be facing hunger in 2030, highlighting the immense challenge of achieving the zero hunger target.

People experiencing moderate food insecurity are typically unable to eat a healthy, balanced diet on a regular basis because of income or other resource constraints.

Why are there so many hungry people?

Shockingly, the world is back at hunger levels not seen since 2005, and food prices remain higher in more countries than in the period 2015–2019. Along with conflict, climate shocks, and rising cost of living, civil insecurity and declining food production have all contributed to food scarcity and high food prices.

Investment in the agriculture sector is critical for reducing hunger and poverty, improving food security, creating employment and building resilience to disasters and shocks.

Why should I care?

We all want our families to have enough food to eat what is safe and nutritious. A world with zero hunger can positively impact our economies, health, education, equality and social development.

It’s a key piece of building a better future for everyone. Additionally, with hunger limiting human development, we will not be able to achieve the other sustainable development goals such as education, health and gender equality.

How can we achieve Zero Hunger?

Food security requires a multi-dimensional approach – from social protection to safeguard safe and nutritious food especially for children to transforming food systems to achieve a more inclusive and sustainable world. There will need to be investments in rural and urban areas and in social protection so poor people have access to food and can improve their livelihoods.

What can we do to help?

You can make changes in your own life—at home, at work and in the community—by supporting local farmers or markets and making sustainable food choices, supporting good nutrition for all, and fighting food waste.

You can also use your power as a consumer and voter, demanding businesses and governments make the choices and changes that will make Zero Hunger a reality. Join the conversation, whether on social media platforms or in your local communities.

Facts and Figures

Goal 2 targets.

• Despite global efforts, in 2022, an estimated 45 million children under the age of 5 suffered from wasting, 148 million had stunted growth and 37 million were overweight. A fundamental shift in trajectory is needed to achieve the 2030 nutrition targets.
• To achieve zero hunger by 2030, urgent coordinated action and policy solutions are imperative to address entrenched inequalities, transform food systems, invest in sustainable agricultural practices, and reduce and mitigate the impact of conflict and the pandemic on global nutrition and food security.

The United Nations Sustainable Development Goals Essay

The Sustainable Development Goals are a kind of call to action emanating from all countries – poor, rich, and moderately developed. This call aims to improve the well-being of people and animals and protect our planet and nature. All countries admit that poverty liquidation measures must be taken at the same time with efforts to improve economic growth. Also, addressing a range of issues in the areas of education, health, social protection, and employment as well as combating climate change and protecting the environment should be done as soon as possible. The purpose of this paper is to list and discuss the United Nations’ seventeen Sustainable Development Goals.

The United Nations or U.N. is an intergovernmental organization that seeks to keep international safety, peace, and security, develop healthy and friendly relationships between people from different countries, be the center for harmonizing the actions of nations, and achieve international cooperation. The Sustainable Development Goals are considered to be the foundation for a better future for everyone. These goals appeal to the global problems that are related to inequality, poverty, environmental degradation, climate change, justice, and peace (“About the Sustainable Development Goals”). All the seventeen goals are connected with each other, and the United Nations want to achieve all of them by 2030.

The first goal is to get rid of all kinds of poverty by ensuring that all people have equal rights and access to basic services, economic resources, ownership, natural resources, inherited property, financial services, and relevant new technologies. The second aim is to eliminate hunger by providing all people with permanent access to adequate, healthy, nutritious, and safe food. The third goal is to promote well-being and ensure healthy lives for all people of all ages. It may be achieved by reducing mortality rate, ending preventable deaths of children and newborns and premature mortality, increasing health financing.

Also, this goal’s steps are completing the epidemics of tuberculosis, AIDS, tropical diseases, and malaria and combating water-borne diseases, hepatitis, and other infectious sicknesses. The fourth aim is to establish quality education by providing all boys and girls with quality, free, and equitable early childhood development, care, preprimary, primary, and secondary education (“About the Sustainable Development Goals”). Also, it is necessary to make sure that all people have equal access to affordable and quality higher education and that all gender disparities in education are eliminated.

Goal number five is to achieve gender equality by ending discrimination, harmful practices, and violence against all girls and women all over the world. The sixth aim is to provide all people with clean and safe water by eliminating dumping, reducing pollution, and minimizing the release of dangerous materials and chemicals. Also, it is important to halve the amount of wasted water and increase reuse and recycling. The seventh aim is to provide people with access to reliable, affordable, modern, and sustainable energy.

It may be achieved by upgrading technology and expanding infrastructure for supplying sustainable and modern energy services for everyone in all developing countries. Goal number eight is to promote employment, sustainable and inclusive economic growth, and decent work for everyone (“About the Sustainable Development Goals”). The ninth goal is to foster innovation, build sustainable infrastructure, and promote stable industrialization by raising industry’s share of GDP and employment and increasing access to communications and information technology.

Aim number ten is to reduce inequality within and among countries by empowering the economic, political, and social inclusion of all people despite their race, age, religion, and other differences. Moreover, it is essential to provide equal opportunities and reduce outcome inequalities by destroying discriminatory policies, laws, and practices. The eleventh goal is to make towns and cities safe, inclusive, sustainable, and resilient by providing access to secure transportation, improving road safety, and protecting and safeguarding the world’s natural and cultural heritage. Aim number twelve is to ensure sustainable and responsible production patterns and consumption.

This may be done by halving global food waste per person and reducing food losses (“About the Sustainable Development Goals”). The thirteenth goal is to take action to fight climate change and its impacts by integrating necessary measures into national policies and strategies and improving people’s awareness of the problem.

The fourteenth aim is to conserve and sustainably use marine resources. People need to prevent or at least reduce all kinds of marine pollution, minimize the impacts of acidification of ocean, and prohibit some forms of fisheries subsidies. Goal number fifteen is to fight with desertification, manage forests, and stop and reverse land degradation. It may be achieved by ensuring the conservation of mountain ecosystems and restoring degraded soil and land.

Aim number sixteen is to promote equitable, inclusive, and peaceful societies by reducing violence and death rates that are related to it, ending exploitation, abuse, trafficking, and torture of children, and reducing bribery and corruption. Finally, the seventeenth goal is to achieve sustainable development by revitalizing the global partnership (“About the Sustainable Development Goals”). In other words, this goal is about strengthening domestic resource mobilization, mobilizing additional financial resources, and assisting developing countries.

To draw a conclusion, one may say that these goals are essential for achieving sustainable development, a safe society and atmosphere, the world’s proper condition, and the prosperity of all people. It is hard to disagree that most of these goals, like combating climate change or protecting the marine resources, are so crucial that they need to be achieved in the nearest future. Unfortunately, it is impossible until all people realize the problems and unite to change the world for the better together.

The 19 papers included in this special issue examined the factors influencing the adoption of climate-smart agriculture (CSA) practices among smallholder farmers and estimated the impacts of CSA adoption on farm production, income, and well-being. Key findings from this special issue include: (1) the variables, including age, gender, education, risk perception and preferences, access to credit, farm size, production conditions, off-farm income, and labour allocation, have a mixed (either positive or negative) influence on the adoption of CSA practices; (2) the variables, including labour endowment, land tenure security, access to extension services, agricultural training, membership in farmers’ organizations, support from non-governmental organizations, climate conditions, and access to information consistently have a positive impact on CSA adoption; (3) diverse forms of capital (physical, social, human, financial, natural, and institutional), social responsibility awareness, and digital advisory services can effectively promote CSA adoption; (4) the establishment of climate-smart villages and civil-society organizations enhances CSA adoption by improving their access to credit; (5) CSA adoption contributes to improved farm resilience to climate change and mitigation of greenhouse gas emissions; (6) CSA adoption leads to higher crop yields, increased farm income, and greater economic diversification; (7) integrating CSA technologies into traditional agricultural practices not only boosts economic viability but also contributes to environmental sustainability and health benefits; and (8) there is a critical need for international collaboration in transferring technology for CSA. Overall, the findings of this special issue highlight that through targeted interventions and collaborative efforts, CSA can play a pivotal role in achieving food security, poverty alleviation, and climate resilience in farming communities worldwide and contribute to the achievements of the United Nations Sustainable Development Goals.

1 Introduction

Climate change reduces agricultural productivity and leads to greater instability in crop production, disrupting the global food supply and resulting in food and nutritional insecurity. In particular, climate change adversely affects food production through water shortages, pest outbreaks, and soil degradation, leading to significant crop yield losses and posing significant challenges to global food security (Kang et al. 2009 ; Läderach et al. 2017 ; Arora 2019 ; Zizinga et al. 2022 ; Mirón et al. 2023 ). United Nations reported that the human population will reach 9.7 billion by 2050. In response, food-calorie production will have to expand by 70% to meet the food demand of the growing population (United Nations 2021 ). Hence, it is imperative to advocate for robust mitigation strategies that counteract the negative impacts of climate change and enhance the flexibility and speed of response in smallholder farming systems.

A transformation of the agricultural sector towards climate-resilient practices can help tackle food security and climate change challenges successfully. Climate-smart agriculture (CSA) is an approach that guides farmers’ actions to transform agrifood systems towards building the agricultural sector’s resilience to climate change based on three pillars: increasing farm productivity and incomes, enhancing the resilience of livelihoods and ecosystems, and reducing and removing greenhouse gas emissions from the atmosphere (FAO 2013 ). Promoting the adoption of CSA practices is crucial to improve smallholder farmers’ capacity to adapt to climate change, mitigate its impact, and help achieve the United Nations Sustainable Development Goals.

Realizing the benefits of adopting CSA, governments in different countries and international organizations such as the Consultative Group on International Agricultural Research (CGIAR), the Food and Agriculture Organisation (FAO) of the United Nations, and non-governmental organizations (NGOs) have made great efforts to scale up and out the CSA. For example, climate-smart villages in India (Alam and Sikka 2019 ; Hariharan et al. 2020 ) and civil society organizations in Africa, Asia, and Latin America (Waters-Bayer et al. 2015 ; Brown 2016 ) have been developed to reduce information costs and barriers and bridge the gap in finance access to promote farmers’ adoption of sustainable agricultural practices, including CSA. Besides, agricultural training programs have been used to enhance farmers’ knowledge of CSA and their adoption of the technology in Ghana (Zakaria et al. 2020 ; Martey et al. 2021 ).

As a result, smallholder farmers worldwide have adopted various CSA practices and technologies (e.g., integrated crop systems, drop diversification, inter-cropping, improved pest, water, and nutrient management, improved grassland management, reduced tillage and use of diverse varieties and breeds, restoring degraded lands, and improved the efficiency of input use) to reach the objectives of CSA (Kpadonou et al. 2017 ; Zakaria et al. 2020 ; Khatri-Chhetri et al. 2020 ; Aryal et al. 2020a ; Waaswa et al. 2022 ; Vatsa et al. 2023 ). In the Indian context, technologies such as laser land levelling and the happy seeder have been promoted widely for their potential in climate change adaptation and mitigation, offering benefits in terms of farm profitability, emission reduction, and water and land productivity (Aryal et al. 2020b ; Keil et al. 2021 ). In some African countries such as Tanzania and Kenya, climate-smart feeding practices in the livestock sector have been suggested to tackle challenges in feed quality and availability exacerbated by climate change, aiming to improve livestock productivity and resilience (García de Jalón et al. 2017 ; Shikuku et al. 2017 ; Radeny et al. 2022 ).

Several studies have investigated the factors influencing farmers’ decisions to adopt CSA practices. They have focused on, for example, farmers’ characteristics (e.g., age, gender, and education), farm-level characteristics (e.g., farm size, land fertility, and land tenure security), socioeconomic factors (e.g., economic conditions), institutional factors (e.g., development programs, membership in farmers’ organizations, and access to agricultural training), climate conditions, and access to information (Aryal et al. 2018 ; Tran et al. 2020 ; Zakaria et al. 2020 ; Kangogo et al. 2021 ; Diro et al. 2022 ; Kifle et al. 2022 ; Belay et al. 2023 ; Zhou et al. 2023 ). For example, Aryal et al. ( 2018 ) found that household characteristics (e.g., general caste, education, and migration status), plot characteristics (e.g., tenure of plot, plot size, and soil fertility), distance to market, and major climate risks are major factors determining farmers’ adoption of multiple CSA practices in India. Tran et al. ( 2020 ) reported that age, gender, number of family workers, climate-related factors, farm characteristics, distance to markets, access to climate information, confidence in the know-how of extension workers, membership in social/agricultural groups, and attitude toward risk are the major factors affecting rice farmers’ decisions to adopt CSA technologies in Vietnam. Diro et al.’s ( 2022 ) analysis revealed that coffee growers’ decisions to adopt CSA practices are determined by their education, extension (access to extension services and participation on field days), and ownership of communication devices, specifically radio in Ethiopia. Zhou et al. 2023 ) found that cooperative membership significantly increases the adoption of climate-smart agricultural practices among banana-producing farmers in China. These studies provide significant insights regarding the factors influencing farmers’ decisions regarding CSA adoption.

A growing body of studies have also estimated the effects of CSA adoption. They have found that CSA practices enhance food security and dietary diversity by increasing crop yields and rural incomes (Amadu et al. 2020 ; Akter et al. 2022 ; Santalucia 2023 ; Tabe-Ojong et al. 2023 ; Vatsa et al. 2023 ; Omotoso and Omotayo 2024 ). For example, Akter et al. ( 2022 ) found that adoption of CSA practices was positively associated with rice, wheat, and maize yields and household income, contributing to household food security in Bangladesh. By estimating data from rice farmers in China, Vatsa et al. ( 2023 ) reported that intensifying the adoption of climate-smart agricultural practices improved rice yield by 94 kg/mu and contributed to food security. Santalucia ( 2023 ) and Omotoso and Omotayo ( 2024 ) found that adoption of CSA practices (improved maize varieties and maize-legume intercropping) increases household dietary diversity and food security among smallholders in Tanzania and Nigeria, respectively.

Agriculture is crucial in climate change, accounting for roughly 20% of worldwide greenhouse gas (GHG) emissions. Additionally, it is responsible for approximately 45% of the global emissions of methane, a potent gas that significantly contributes to heat absorption in the atmosphere. CSA adoption improves farm resilience to climate variability (e.g., Makate et al. 2019 ; Jamil et al. 2021 ) and mitigates greenhouse gas emissions (Israel et al. 2020 ; McNunn et al. 2020 ). For example, Makate et al. ( 2019 ) for southern Africa and Jamil et al. ( 2021 ) for Pakistan found that promoting CSA innovations is crucial for boosting farmers’ resilience to climate change. McNunn et al. ( 2020 ) reported that CSA adoption significantly reduces greenhouse gas emissions from agriculture by increasing soil organic carbon stocks and decreasing nitrous oxide emissions.

Although a growing number of studies have enriched our understanding of the determinants and impacts of ICT adoption, it should be emphasized that no one-size-fits-all approach exists for CSA technology adoption due to geographical and environmental variability. The definitions of CSA should also be advanced to better adapt to changing climate and regional production conditions. Clearly, despite the extensive research on CSA, several gaps remain. First, there is a lack of comprehensive studies that consolidate findings across different geographical regions to inform policymaking effectively. The calls for studies on literature review and meta-analysis to synthesize the findings of the existing studies to make our understanding generalized. Second, although the literature on determinants of CSA adoption is becoming rich, there is a lack of understanding of how CSA adoption is influenced by different forms of capital, social responsibility awareness of farmers’ cultivating family farms, and digital advisory services. Third, there is a lack of understanding of how climate-smart villages and civil society organizations address farmers’ financial constraints and encourage them to adopt modern sustainable agricultural practices, including CSA practices. Fourth, very few studies have explored how CSA adoption influences the benefit–cost ratio of farm production, factor demand, and input substitution. Fifth, no previous studies have reported the progress of research on CSA. Addressing these gaps is crucial for designing and implementing effective policies and programs that support the widespread adoption of CSA practices, thereby contributing to sustainable agricultural development and climate resilience.

We address the research gaps mentioned above and extend the findings in previous studies by organizing a Special Issue on “Climate-Smart Agriculture: Adoption, Impacts, and Implications for Sustainable Development” in the Mitigation and Adaptation Strategies for Global Change (MASGC) journal. We aim to collect high-quality theoretical and applied research papers discussing CSA and seek to comprehensively understand the associations between CSA and sustainable rural and agricultural development. To achieve this goal, we aim to find answers to these questions: What are the CSA practices and technologies (either single or multiple) that are currently adopted in smallholder farming systems? What are the key barriers, challenges, and drivers of promoting CSA practices? What are the impacts of adopting these practices? Answers to these questions will help devise appropriate solutions for promoting sustainable agricultural production and rural development. They will also provide insights for policymakers to design appropriate policy instruments to develop agricultural practices and technologies and promote them to sustainably enhance the farm sector’s resilience to climate change and increase productivity.

Finally, 19 papers were selected after a rigorous peer-review process and published in this special issue. We collected 10 papers investigating the determinants of CSA adoption. Among them, four papers investigated the determinants of CSA adoption among smallholders by reviewing and summarizing the findings in the literature and conducting a meta-analysis. Three papers explored the role of social-economic factors on ICT adoption, including capital, social responsibility awareness, and digital advisory services. Besides, three papers examined the associations between external development interventions, including climate-smart villages and civil-society initiatives, and CSA adoption. We collected eight papers exploring the impacts of CSA adoption. Among them, one paper conducted a comprehensive literature review to summarize the impacts of CSA adoption on crop yields, farm income, and environmental sustainability. Six papers estimated the impacts of CSA adoption on crop yields and farm income, and one paper focused on the impact of CSA adoption on factor demand and input substitution. The last paper included in this special issue delved into the advancements in technological innovation for agricultural adaptation within the context of climate-smart agriculture.

The structure of this paper is as follows: Section  2 summarizes the papers received in this special issue. Section  3 introduces the international conference that was purposely organized for the special issue. Section  4 summarizes the key findings of the 19 papers published in the special issue, followed by a summary of their policy implications, presented in Section  5 . The final section provides a brief conclusion.

3.2 Keynote speeches

The guest editors invited two keynote speakers to present at the two-day conference. They were Prof. Edward B. Barbier from the Colorado State University in the United States Footnote 2 and Prof. Tatsuyoshi Saijo from Kyoto University of Advanced Science in Japan. Footnote 3

Prof. Edward Barbier gave a speech, “ A Policy Strategy for Climate-Smart Agriculture for Sustainable Rural Development ”, on 10th October 2023. He outlined a strategic approach for integrating CSA into sustainable rural development, particularly within emerging markets and developing economies. He emphasized the necessity of CSA and nature-based solutions (NbS) to tackle food security, climate change, and rural poverty simultaneously. Highlighting the substantial investment needs and the significant role of international and domestic financing, Prof. Barbier advocated reducing harmful subsidies in agriculture, forestry, fishing, and fossil fuel consumption to redirect funds toward CSA and NbS investments. He also proposed the implementation of a tropical carbon tax as an innovative financing mechanism. By focusing on recycling environmentally harmful subsidies and leveraging additional funding through public and private investments, Prof. Barbier’s strategy aims to foster a “win–win” scenario for climate action and sustainable development, underscoring the urgency of adopting comprehensive policies to mobilize the necessary resources for these critical investments.

Prof. Tatsuyoshi Saijo, gave his speech, “ Future Design ”, on 11th October 2023. He explored the significant impact of the Haber–Bosch process on human civilization and the environment. Prof. Saijo identifies this process, which synthetically fixed nitrogen from the atmosphere to create ammonia for fertilizers and other products, as the greatest invention from the twentieth century to the present, fundamentally transforming the world’s food production and enabling the global population and industrial activities to expand dramatically. He also discussed the environmental costs of this technological advancement, including increased greenhouse gas emissions, pollution, and contribution to climate change. Prof. Saijo then introduced the concept of “Future Design” as a method to envision and implement sustainable social systems that consider the well-being of future generations. He presented various experiments and case studies from Japan and beyond, showing how incorporating perspectives of imaginary future generations into decision-making processes can lead to more sustainable choices. By doing so, Prof. Saijo suggested that humanity can address the “Intergenerational Sustainability Dilemma” and potentially avoid the ecological overshoot and collapse faced by past civilizations like Easter Island. He called for a redesign of social systems to activate “futurability”, where individuals derive happiness from decisions that benefit future generations, ultimately aiming to ensure the long-term survival of humankind amidst environmental challenges.

4 Summary of published articles

As a result of a rigorous double-anonymized reviewing process, the special issue accepted 19 articles for publication. These studies have investigated the determinants and impacts of CSA adoption. Table 1 in the Appendix summarises the CSA technologies and practices considered in each paper. Below, we summarize the key findings of the contributions based on their research themes.

4.1 Determinants of CSA adoption among smallholders

4.1.1 influencing factors of csa adoption from literature review.

Investigating the factors influencing farmers’ adoption of CSA practices through a literature review helps offer a comprehensive understanding of the multifaceted determinants of CSA adoption. Investigating the factors influencing farmers’ adoption of CSA practices through a literature review helps provide a comprehensive understanding of the determinants of CSA adoption. Such analyses help identify consistent trends and divergences in how different variables influence farmers’ CSA adoption decisions. In this special issue, we collected four papers that reviewed the literature and synthesized the factors influencing farmers’ decisions to adopt CSA.

Li, Ma and Zhu’s paper, “ A systematic literature review of factors influencing the adoption of climate-smart agricultural practices ”, conducted a systematic review of the literature on the adoption of CSA, summarizing the definitions of CSA practices and the factors that influence farmers’ decisions to adopt these practices. The authors reviewed 190 studies published between 2013 and 2023. They broadly defined CSA practices as “agricultural production-related and unrelated practices that can help adapt to climate change and increase agricultural outputs”. Narrowly, they defined CSA practices as “agricultural production-related practices that can effectively adapt agriculture to climate change and reinforce agricultural production capacity”. The review identified that many factors, including age, gender, education, risk perception, preferences, access to credit, farm size, production conditions, off-farm income, and labour allocation, have a mixed (positive or negative) influence on the adoption of CSA practices. Variables such as labour endowment, land tenure security, access to extension services, agricultural training, membership in farmers’ organizations, support from non-governmental organizations (NGOs), climate conditions, and access to information were consistently found to positively influence CSA practice adoption.

Thottadi and Singh’s paper, “ Climate-smart agriculture (CSA) adaptation, adaptation determinants and extension services synergies: A systematic review ””, reviewed 45 articles published between 2011 and 2022 to explore different CAS practices adopted by farmers and the factors determining their adoption. They found that CSA practices adopted by farmers can be categorized into five groups. These included resilient technologies (e.g., early maturing varieties, drought-resistant varieties, and winter ploughing), management strategies (e.g., nutrient management, water management, and pest management), conservation technologies (e.g., vermicomposting and residue management, drip and sprinkler irrigation, and soil conservation), diversification of income security (e.g., mixed farming, livestock, and crop diversification), and risk mitigation strategies (e.g., contingent planning, adjusting plant dates, and crop insurance). They also found that farmers’ decisions to adopt CSA practices are mainly determined by individual characteristics (age, gender, and education), socioeconomic factors (income and wealth), institutional factors (social group, access to credit, crop insurance, distance, land tenure, and rights), behavioural factors (climate perception, farmers’ perception on CSA, Bookkeeping), and factor endowments (family labour, machinery, and land size). The authors emphasized that extension services improved CSA adaptation by reducing information asymmetry.

Naveen, Datta, Behera and Rahut’s paper, “ Climate-Smart Agriculture in South Asia: Exploring Practices, Determinants, and Contribution to Sustainable Development Goals ”, offered a comprehensive systematic review of 78 research papers on CSA practice adoption in South Asia. Their objective was to assess the current implementation of CSA practices and to identify the factors that influence farmers’ decisions to adopt these practices. They identified various CSA practices widely adopted in South Asia, including climate-resilient seeds, zero tillage, water conservation, rescheduling of planting, crop diversification, soil conservation and water harvesting, and agroforestry. They also identified several key factors that collectively drive farmers’ adoption of CSA practices. These included socioeconomic factors (age, education, livestock ownership, size of land holdings, and market access), institutional factors (access to information and communication technology, availability of credit, input subsidies, agricultural training and demonstrations, direct cash transfers, and crop insurance), and climatic factors (notably rising temperatures, floods, droughts, reduced rainfall, and delayed rainfall).

Wang, Wang and Fu’s paper, “ Can social networks facilitate smallholders’ decisions to adopt Climate-smart Agriculture technologies? A three-level meta-analysis ”, explored the influence of social networks on the adoption of CSA technologies by smallholder farmers through a detailed three-level meta-analysis. This analysis encompassed 26 empirical studies, incorporating 150 effect sizes. The authors reported a modest overall effect size of 0.065 between social networks and the decision-making process for CSA technology adoption, with an 85.21% variance observed among the sample effect sizes. They found that over half (55.17%) of this variance was attributed to the differences in outcomes within each study, highlighting the impact of diverse social network types explored across the studies as significant contributors. They did not identify publication bias in this field. Among the three types of social networks (official-advising network, peer-advising network, and kinship and friendship network), kinship and friendship networks are the most effective in facilitating smallholders’ decisions to adopt climate-smart agriculture technologies.

4.1.2 Socioeconomic factors influencing CSA adoption

We collected three papers highlighting the diverse forms of capital, social responsibility awareness, and effectiveness of digital advisory services in promoting CSA in India, China and Ghana. These studies showcase how digital tools can significantly increase the adoption of CSA technologies, how social responsibility can motivate CSA practices and the importance of various forms of capital in CSA strategy adoption.

Sandilya and Goswami’s paper, “ Effect of different forms of capital on the adoption of multiple climate-smart agriculture strategies by smallholder farmers in Assam, India ”, delved into the determinants behind the adoption of CSA strategies by smallholder farmers in Nagaon district, India, a region notably prone to climate adversities. The authors focused on six types of capital: physical, social, human, financial, natural, and institutional. They considered four CSA practices: alternate land use systems, integrated nutrient management, site-specific nutrient management, and crop diversification. Their analyses encompassed a dual approach, combining a quantitative analysis via a multivariate probit model with qualitative insights from focus group discussions. They found that agricultural cooperatives and mobile applications, both forms of social capital, play a significant role in facilitating the adoption of CSA. In contrast, the authors also identified certain barriers to CSA adoption, such as the remoteness of farm plots from all-weather roads (a component of physical capital) and a lack of comprehensive climate change advisories (a component of institutional capital). Furthermore, the authors highlighted the beneficial impact of irrigation availability (a component of physical capital) on embracing alternate land use and crop diversification strategies. Additionally, the application of indigenous technical knowledge (a component of human capital) and the provision of government-supplied seeds (a component of institutional capital) were found to influence the adoption of CSA practices distinctly.

Ye, Zhang, Song and Li’s paper, “ Social Responsibility Awareness and Adoption of Climate-smart Agricultural Practices: Evidence from Food-based Family Farms in China ”, examined whether social responsibility awareness (SRA) can be a driver for the adoption of CSA on family farms in China. Using multiple linear regression and hierarchical regression analyses, the authors analyzed data from 637 family farms in five provinces (Zhejiang, Shandong, Henan, Heilongjiang, and Hebei) in China. They found that SRA positively impacted the adoption of CSA practice. Pro-social motivation and impression management motivation partially and completely mediated the relationship between SRA and the adoption of CSA practices.

Asante, Ma, Prah and Temoso’s paper, “ Promoting the adoption of climate-smart agricultural technologies among maize farmers in Ghana: Using digital advisory services ”, investigated the impacts of digital advisory services (DAS) use on CSA technology adoption and estimated data collected from 3,197 maize farmers in China. The authors used a recursive bivariate probit model to address the self-selection bias issues when farmers use DAS. They found that DAS notably increases the propensity to adopt drought-tolerant seeds, zero tillage, and row planting by 4.6%, 4.2%, and 12.4%, respectively. The average treatment effect on the treated indicated that maize farmers who use DAS are significantly more likely to adopt row planting, zero tillage, and drought-tolerant seeds—by 38.8%, 24.9%, and 47.2%, respectively. Gender differences in DAS impact were observed; male farmers showed a higher likelihood of adopting zero tillage and drought-tolerant seeds by 2.5% and 3.6%, respectively, whereas female farmers exhibited a greater influence on the adoption of row planting, with a 2.4% probability compared to 1.5% for males. Additionally, factors such as age, education, household size, membership in farmer-based organizations, farm size, perceived drought stress, perceived pest and disease incidence, and geographic location were significant determinants in the adoption of CSA technologies.

4.1.3 Climate-smart villages and CSA adoption

Climate-Smart Villages (CSVs) play a pivotal role in promoting CSA by significantly improving farmers’ access to savings and credit, and the adoption of improved agricultural practices among smallholder farmers. CSV interventions demonstrate the power of community-based financial initiatives in enabling investments in CSA technologies. In this special issue, we collected two insightful papers investigating the relationship between CSVs and the adoption of CSA practices, focusing on India and Kenya.

Villalba, Joshi, Daum and Venus’s paper, “ Financing Climate-Smart Agriculture: A Case Study from the Indo-Gangetic Plains ”, investigated the adoption and financing of CSA technologies in India, focusing on two capital-intensive technologies: laser land levelers and happy seeders. Conducted in Karnal, Haryana, within the framework of Climate-Smart-Villages, the authors combined data from a household survey of 120 farmers, interviews, and focus group discussions with stakeholders like banks and cooperatives. The authors found that adoption rates are high, with 77% for laser land levelers and 52% for happy seeders, but ownership is low, indicating a preference for renting from Custom-Hiring Centers. Farmers tended to avoid formal banking channels for financing, opting instead for informal sources like family, savings, and money lenders, due to the immediate access to credit and avoidance of bureaucratic hurdles. The authors suggested that institutional innovations and governmental support could streamline credit access for renting CSA technologies, emphasizing the importance of knowledge transfer, capacity building, and the development of digital tools to inform farmers about financing options. This research highlights the critical role of financing mechanisms in promoting CSA technology adoption among smallholder farmers in climate-vulnerable regions.

Asseldonk, Oostendorp, Recha, Gathiaka, Mulwa, Radeny Wattel and Wesenbeeck’s paper, “ Distributional impact of climate‑smart villages on access to savings and credit and adoption of improved climate‑smart agricultural practices in the Nyando Basin, Kenya ”, investigated the impact of CSV interventions in Kenya on smallholder farmers’ access to savings, credit, and adoption of improved livestock breeds as part of CSA practices. The authors employed a linear probability model to estimate a balanced panel of 118 farm households interviewed across 2017, 2019, and 2020. They found that CSV interventions significantly increased the adoption of improved livestock breeds and membership in savings and credit groups, which further facilitated the adoption of these improved breeds. The findings highlighted that community-based savings and loan initiatives effectively enable farmers to invest in CSA practices. Although there was a sustained positive trend in savings and loans group membership, the adoption of improved livestock did not show a similar sustained increase. Moreover, the introduction of improved breeds initially benefited larger livestock owners more. However, credit availability was found to reduce this inequity in ownership among participants, making the distribution of improved livestock more equitable within CSVs compared to non-CSV areas, thus highlighting the potential of CSV interventions to reduce disparities in access to improved CSA practices.

4.1.4 Civil-society initiatives and CSA adoption

Civil society initiatives are critical in promoting CSA by embedding its principles across diverse agricultural development projects. These initiatives enhance mitigation, adaptation, and food security efforts for smallholder farmers, demonstrating the importance of varied implementation strategies to address the challenges of CSA. We collected one paper investigating how civil society-based development projects in Asia and Africa incorporated CSA principles to benefit smallholder farmers and local communities.

Davila, Jacobs, Nadeem, Kelly and Kurimoto’s paper, “ Finding climate smart agriculture in civil-society initiatives ”, scrutinized the role of international civil society and non-government organizations (NGOs) in embedding CSA principles within agricultural development projects aimed at enhancing mitigation, adaptation, and food security. Through a thematic analysis of documentation from six projects selected on the basis that they represented a range of geographical regions (East Africa, South, and Southeast Asia) and initiated since 2009, the authors assessed how development programs incorporate CSA principles to support smallholder farmers under CSA’s major pillars. They found heterogeneous application of CSA principles across the projects, underscoring a diversity in implementation strategies despite vague definitions and focuses of CSA. The projects variedly contributed to greening and forests, knowledge exchange, market development, policy and institutional engagement, nutrition, carbon and climate action, and gender considerations.

4.2 Impacts of CSA adoption

4.2.1 impacts of csa adoption from literature review.

A comprehensive literature review on the impacts of CSA adoption plays an indispensable role in bridging the gap between theoretical knowledge and practical implementation in the agricultural sector. In this special issue, we collected one paper that comprehensively reviewed the literature on the impacts of CSA adoption from the perspective of the triple win of CSA.

Zheng, Ma and He’s paper, “ Climate-smart agricultural practices for enhanced farm productivity, income, resilience, and Greenhouse gas mitigation: A comprehensive review ”, reviewed 107 articles published between 2013–2023 to distill a broad understanding of the impacts of CSA practices. The review categorized the literature into three critical areas of CSA benefits: (a) the sustainable increase of agricultural productivity and incomes; (b) the adaptation and enhancement of resilience among individuals and agrifood systems to climate change; and (c) the reduction or avoidance of greenhouse gas (GHG) emissions where feasible. The authors found that CSA practices significantly improved farm productivity and incomes and boosted technical and resource use efficiency. Moreover, CSA practices strengthened individual resilience through improved food consumption, dietary diversity, and food security while enhancing agrifood systems’ resilience by mitigating production risks and reducing vulnerability. Additionally, CSA adoption was crucial in lowering Greenhouse gas emissions and fostering carbon sequestration in soils and biomass, contributing to improved soil quality.

4.2.2 Impacts on crop yields and farm income

Understanding the impact of CSA adoption on crop yields and income is crucial for improving agricultural resilience and sustainability. In this special issue, we collected three papers highlighting the transformative potential of CSA practices in boosting crop yields, commercialization, and farm income. One paper focuses on India and the other concentrates on Ghana and Kenya.

Tanti, Jena, Timilsina and Rahut’s paper, “ Enhancing crop yields and farm income through climate-smart agricultural practices in Eastern India ”, examined the impact of CSA practices (crop rotation and integrated soil management practices) on crop yields and incomes. The authors used propensity score matching and the two-stage least square model to control self-selection bias and endogeneity and analyzed data collected from 494 farm households in India. They found that adopting CSA practices increases agricultural income and paddy yield. The crucial factor determining the adoption of CSA practices was the income-enhancing potential to transform subsistence farming into a profoundly ingrained farming culture.

Asante, Ma, Prah and Temoso’s paper, “ Farmers’ adoption of multiple climate-smart agricultural technologies in Ghana: Determinants and impacts on maize yields and net farm income ”, investigated the factors influencing maize growers’ decisions to adopt CSA technologies and estimated the impact of adopting CSA technologies on maize yields and net farm income. They considered three CSA technology types: drought-resistant seeds, row planting, and zero tillage. The authors used the multinomial endogenous switching regression model to estimate the treatment effect of CSA technology adoption and analyze data collected from 3,197 smallholder farmers in Ghana. They found that farmer-based organization membership, education, resource constraints such as lack of land, access to markets, and production shocks such as perceived pest and disease stress and drought are the main factors that drive farmers’ decisions to adopt CSA technologies. They also found that integrating any CSA technology or adopting all three CSA technologies greatly enhances maize yields and net farm income. Adopting all three CSA technologies had the largest impact on maize yields, while adopting row planting and zero tillage had the greatest impact on net farm income.

Mburu, Mburu, Nyikal, Mugera and Ndambi’s paper, “ Assessment of Socioeconomic Determinants and Impacts of Climate-Smart Feeding Practices in the Kenyan Dairy Sector ”, assessed the determinants and impacts of adopting climate-smart feeding practices (fodder and feed concentrates) on yield, milk commercialization, and household income. The authors used multinomial endogenous switching regression to account for self-selection bias arising from observable and unobservable factors and estimated data collected from 665 dairy farmers in Kenya. They found that human and social capital, resource endowment, dairy feeding systems, the source of information about feeding practices, and perceived characteristics were the main factors influencing farmers’ adoption of climate-smart feeding practices. They also found that combining climate-smart feed concentrates and fodder significantly increased milk productivity, output, and dairy income. Climate-smart feed concentrates yielded more benefits regarding dairy milk commercialization and household income than climate-smart fodder.

4.2.3 Impacts on crop yields

Estimating the impacts of CSA adoption on crop yields is crucial for enhancing food security, improving farmers’ resilience to climate change, and guiding policy and investment towards sustainable agricultural development. In this special issue, we collected one paper that provided insights into this field.

Singh, Bisaria, Sinha, Patasaraiya and Sreerag’s paper, “ Developing A Composite Weighted Indicator-based Index for Monitoring and Evaluating Climate-Smart Agriculture in India ”, developed a composite index based on a weighted index to calculate the Climate Smart Score (CSS) at the farm level in India and tested the relationship between computed CSS and farm-level productivity. Through an intensive literature review, the authors selected 34 indicators, which were then grouped into five dimensions for calculating CSS. These dimensions encompassed governance (e.g., land ownership, subsidized fertilizer, and subsidized seeds), farm management practices (mulching, zero tillage farming, and inter-cropping and crop diversification), environment management practices (e.g., not converting forested land into agricultural land and Agroforestry/plantation), energy management (e.g., solar water pump and Biogas digester), and awareness and training (e.g., knowledge of climate-related risk and timely access to weather and agro-advisory). They tested the relationship between CSS and farm productivity using data collected from 315 farmers. They found that improved seeds, direct seeding of rice, crop diversification, zero tillage, agroforestry, crop residue management, integrated nutrient management, and training on these practices were the most popular CSA practices the sampled farmers adopted. In addition, there was a positive association between CSS and paddy, wheat, and maize yields. This finding underscores the beneficial impact of CSA practices on enhancing farm productivity.

4.2.4 Impacts on incomes and benefit–cost ratio

Understanding the income effects of CSA adoption is crucial for assessing its impact on household livelihoods, farm profitability, and income diversity. Quantifying income enhancements would contribute to informed decision-making and investment strategies to improve farming communities’ economic well-being. In this special issue, we collected two papers looking into the effects of CSA adoption on income.

Sang, Chen, Hu and Rahut’s paper, “ Economic benefits of climate-smart agricultural practices: Empirical investigations and policy implications ”, investigated the impact of CSA adoption intensity on household income, net farm income, and income diversity. They used the two-stage residual inclusion model to mitigate the endogeneity of CSA adoption intensity and analyzed the 2020 China Rural Revitalization Survey data. They also used the instrumental-variable-based quantile regression model to investigate the heterogeneous impacts of CSA adoption intensity. The authors found that the education level of the household head and geographical location determine farmers’ adoption intensity of CSAs.CSA practices. The higher levels of CSA adoption were positively and significantly associated with higher household income, net farm income, and income diversity. They also found that while the impact of CSA adoption intensity on household income escalates across selected quantiles, its effect on net farm income diminishes over these quantiles. Additionally, the study reveals that CSA adoption intensity notably enhances income diversity at the 20th quantile only.

Kandulu, Zuo, Wheeler, Dusingizimana and Chagund’s paper, “ Influence of climate-smart technologies on the success of livestock donation programs for smallholder farmers in Rwanda ”, investigated the economic, environmental, and health benefits of integrating CSA technologies —specifically barns and biogas plants—into livestock donation programs in Rwanda. Employing a stochastic benefit–cost analysis from the perspective of the beneficiaries, the authors assessed the net advantages for households that receive heifers under an enhanced program compared to those under the existing scheme. They found that incorporating CSA technologies not only boosts the economic viability of these programs but also significantly increases the resilience and sustainability of smallholder farming systems. More precisely, households equipped with cows and CSA technologies can attain net benefits up to 3.5 times greater than those provided by the current program, with the benefit–cost ratios reaching up to 5. Furthermore, biogas technology reduces deforestation, mitigating greenhouse gas emissions, and lowering the risk of respiratory illnesses, underscoring the multifaceted advantages of integrating such innovations into livestock donation initiatives.

4.2.5 Impacts on factor demand and input substitution

Estimating the impacts of CSA adoption on factor demand and input substitution is key to optimizing resource use, reducing environmental footprints, and ensuring agricultural sustainability by enabling informed decisions on efficient input use and technology adoption. In this field, we collected one paper that enriched our understanding in this field. Understanding the impacts of CSA adoption on factor demand, input substitution, and financing options is crucial for promoting sustainable farming in diverse contexts. In this special issue, we collected one paper comprehensively discussing how CSA adoption impacted factor demand and input substitution.

Kehinde, Shittu, Awe and Ajayi’s paper, “ Effects of Using Climate-Smart Agricultural Practices on Factor Demand and Input Substitution among Smallholder Rice Farmers in Nigeria ”, examined the impacts of agricultural practices with CSA potential (AP-CSAPs) on the demand of labour and other production factors (seed, pesticides, fertilizers, and mechanization) and input substitution. The AP-CSAPs considered in this research included zero/minimum tillage, rotational cropping, green manuring, organic manuring, residue retention, and agroforestry. The authors employed the seemingly unrelated regression method to estimate data collected from 1,500 smallholder rice farmers in Nigeria. The authors found that labour and fertilizer were not easily substitutable in the Nigerian context; increases in the unit price of labour (wage rate) and fertilizer lead to a greater budget allocation towards these inputs. Conversely, a rise in the cost of mechanization services per hectare significantly reduced labour costs while increasing expenditure on pesticides and mechanization services. They also found that most AP-CSAPs were labour-intensive, except for agroforestry, which is labor-neutral. Organic manure and residue retention notably conserved pesticides, whereas zero/minimum tillage practices increased the use of pesticides and fertilizers. Furthermore, the demand for most production factors, except pesticides, was found to be price inelastic, indicating that price changes do not significantly alter the quantity demanded.

4.3 Progress of research on CSA

Understanding the progress of research on CSA is essential for identifying and leveraging technological innovations—like greenhouse advancements, organic fertilizer products, and biotechnological crop improvements—that support sustainable agricultural adaptation. This knowledge enables the integration of nature-based strategies, informs policy, and underscores the importance of international cooperation in overcoming patent and CSA adoption challenges to ensure global food security amidst climate change. We collected one paper in this field.

Tey, Brindal, Darham and Zainalabidin’s paper, “ Adaptation technologies for climate-smart agriculture: A patent network analysis ”, delved into the advancements in technological innovation for agricultural adaptation within the context of CSA by analyzing global patent databases. The authors found that greenhouse technologies have seen a surge in research and development (R&D) efforts, whereas composting technologies have evolved into innovations in organic fertilizer products. Additionally, biotechnology has been a significant focus, aiming to develop crop traits better suited to changing climate conditions. A notable emergence is seen in resource restoration innovations addressing climate challenges. These technologies offer a range of policy options for climate-smart agriculture, from broad strategies to specific operational techniques, and pave the way for integration with nature-based adaptation strategies. However, the widespread adoption and potential impact of these technologies may be hindered by issues related to patent ownership and the path dependency this creates. Despite commercial interests driving the diffusion of innovation, international cooperation is clearly needed to enhance technology transfer.

5 Summary of key policy implications

The collection of 19 papers in this special issue sheds light on the critical aspects of promoting farmers’ adoption of CSA practices, which eventually help enhance agricultural productivity and resilience, reduce greenhouse gas emissions, improve food security and soil health, offer economic benefits to farmers, and contribute to sustainable development and climate change adaptation. We summarize and discuss the policy implications derived from this special issue from the following four aspects:

5.1 Improving CSA adoption through extension services

Extension services help reduce information asymmetry associated with CSA adoption and increase farmers’ awareness of CSA practices’ benefits, costs, and risks while addressing their specific challenges. Therefore, the government should improve farmers’ access to extension services. These services need to be inclusive and customized to meet the gender-specific needs and the diverse requirements of various farming stakeholders. Additionally, fostering partnerships between small and medium enterprises and agricultural extension agents is crucial for enhancing the local availability of CSA technologies. Government-sponsored extension services should prioritize equipping farmers with essential CSA skills, ensuring they are well-prepared to implement these practices. This structured approach will streamline the adoption process and significantly improve the effectiveness of CSA initiatives.

5.2 Facilitating CSA adoption through farmers’ organizations

Farmers’ organizations, such as village cooperatives, farmer groups, and self-help groups, play a pivotal role in facilitating farmers’ CSA adoption and empowering rural women’s adoption through effective information dissemination and the use of agricultural apps. Therefore, the government should facilitate the establishment and development of farmers’ organizations and encourage farmers to join those organizations as members. In particular, the proven positive impacts of farmer-based organizations (FBOs) highlight the importance of fostering collaborations between governments and FBOs. Supporting farmer cooperatives with government financial and technical aid is essential for catalyzing community-driven climate adaptation efforts. Furthermore, the successful use of DAS in promoting CSA adoption underscores the need for government collaboration with farmer groups to expand DAS utilization. This includes overcoming usage barriers and emphasizing DAS’s reliability as a source of climate-smart information. By establishing and expanding digital hubs and demonstration centres in rural areas, farmers can access and experience DAS technologies firsthand, leading to broader adoption and integration into their CSA practices.

5.3 Enhancing CSA adoption through agricultural training and education

Agricultural training and education are essential in enhancing farmers’ adoption of CSA. To effectively extend the reach of CSA practices, the government should prioritize expanding rural ICT infrastructure investments and establish CSA training centres equipped with ICT tools that target key demographics such as women and older people, aiming to bridge the digital adoption gaps. Further efforts should prioritize awareness and training programs to ensure farmers can access weather and agro-advisory services. These programs should promote the use of ICT-based tools through collaborations with technology providers and include regular CSA training and the establishment of demonstration fields that showcase the tangible benefits of CSA practices.

Education plays a vital role in adopting CAPs, suggesting targeted interventions such as comprehensive technical training to assist farmers with limited educational backgrounds in understanding the value of CAPs, ultimately improving their adoption rates. Establishing robust monitoring mechanisms is crucial to maintaining farmer engagement and success in CSA practices. These mechanisms will facilitate the ongoing adoption and evaluation of CSA practices and help educate farmers on the long-term benefits. Centralizing and disseminating information about financial products and subsidies through various channels, including digital platforms tailored to local languages and contexts, is essential. This approach helps educate farmers on financing options and requirements, supporting the adoption of CSA technologies among smallholder farmers. Lastly, integrating traditional and local knowledge with scientific research and development can effectively tailor CSA initiatives. This integration requires the involvement of a range of stakeholders, including NGOs, to navigate the complexities of CSA and ensure that interventions are effective but also equitable and sustainable. The enhanced capacity of institutions and their extension teams will further support these CSA initiatives.

5.4 Promoting CSA adoption through establishing social networks and innovating strategies

The finding that social networks play a crucial role in promoting the adoption of CSA suggests that implementing reward systems to incentivize current CSA adopters to advocate for climate-smart practices within their social circles could be an effective strategy to promote CSA among farmers. The evidence of a significant link between family farms’ awareness of social responsibility and their adoption of CSA highlights that governments should undertake initiatives, such as employing lectures and pamphlets, to enhance family farm operating farmers’ understanding of social responsibility. The government should consider introducing incentives that foster positive behavioural changes among family farms to cultivate a more profound commitment to social responsibility. The government can also consider integrating social responsibility criteria into the family farm awards and recognition evaluation process. These measures would encourage family farms to align their operations with broader social and environmental goals, promoting CSA practices.

Combining traditional incentives, such as higher wages and access to improved agricultural inputs, with innovative strategies like community-driven development for equipment sharing and integrating moral suasion with Payment for Ecosystem Services would foster farmers’ commitment to CSA practices. The finding that technological evolution plays a vital role in shaping adaptation strategies for CSA highlights the necessity for policy instruments that not only leverage modern technologies but also integrate them with traditional, nature-based adaptation strategies, enhancing their capacity to address specific CSA challenges. Policymakers should consider the region’s unique socioeconomic, environmental, and geographical characteristics when promoting CSA, moving away from a one-size-fits-all approach to ensure the adaptability and relevance of CSA practices across different agricultural landscapes. They should foster an environment that encourages the reporting of all research outcomes to develop evidence-based policies that are informed by a balanced view of CSA’s potential benefits and limitations.

Finally, governance is critical in creating an enabling environment for CSA adoption. Policies should support CSA practices and integrate environmental sustainability to enhance productivity and ecosystem health. Development programs must offer financial incentives, establish well-supported voluntary schemes, provide robust training programs, and ensure the wide dissemination of informational tools. These measures are designed to help farmers integrate CAPs into their operations, improving economic and operational sustainability.

6 Concluding remarks

This special issue has provided a wealth of insights into the adoption and impact of CSA practices across various contexts, underscoring the complexity and multifaceted nature of CSA implementation. The 19 papers in this special issue collectively emphasize the importance of understanding local conditions, farmer characteristics, and broader socioeconomic and institutional factors that influence CSA adoption. They highlight the crucial role of extension services, digital advisory services, social responsibility awareness, and diverse forms of capital in facilitating the adoption of CSA practices. Moreover, the findings stress the positive impact of CSA on farm productivity, income diversification, and resilience to climate change while also pointing out the potential for CSA practices to address broader sustainability goals.

Significantly, the discussions underline the need for policy frameworks that are supportive and adaptive, tailored to specific regional and local contexts to promote CSA adoption effectively. Leveraging social networks, enhancing access to financial products and mechanisms, and integrating technological innovations with traditional agricultural practices are vital strategies for scaling CSA adoption. Furthermore, the discussions advocate for a balanced approach that combines economic incentives with moral persuasion and community engagement to foster sustainable agricultural practices.

These comprehensive insights call for concerted efforts from policymakers, researchers, extension agents, and the agricultural community to foster an enabling environment for CSA. Such an environment would support knowledge exchange, financial accessibility, and the adoption of CSA practices that contribute to the resilience and sustainability of agricultural systems in the face of climate change. As CSA continues to evolve, future research should focus on addressing the gaps identified, exploring innovative financing and technology dissemination models, and assessing the long-term impacts of CSA practices on agricultural sustainability and food security. This special issue lays the groundwork for further exploration and implementation of CSA practices, aiming to achieve resilient, productive, and sustainable agricultural systems worldwide and contribute to the achievements of the United Nations Sustainable Development Goals.

Metrics details

Sustainable development goal 13 centres on calls for urgent action to combat climate change and its impacts. The aim of this scoping review was to map the published literature for existing evidence on the association between the Sustainable Development Goal (SDG) 13 and early childhood caries (ECC).

The scoping review followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) guidelines. In August 2023, a search was conducted in PubMed, Web of Science, and Scopus using search terms related to SDG13 and ECC. Only English language publications were extracted. There was no restriction on the type of publications included in the study. A summary of studies that met the inclusion criteria was conducted highlighting the countries where the studies were conducted, the study designs employed, the journals (dental/non-dental) in which the studies were published, and the findings. In addition, the SDG13 indicators to which the study findings were linked was reported.

The initial search yielded 113 potential publications. After removing 57 duplicated papers, 56 publications underwent title and abstract screening, and two studies went through full paper review. Four additional papers were identified from websites and searching the references of the included studies. Two of the six retrieved articles were from India, and one was China, Japan, the United States, and the United Kingdom respectively. One paper was based on an intervention simulation study, two reported findings from archeologic populations and three papers that were commentaries/opinions. In addition, four studies were linked to SDG 13.1 and they suggested an increased risk for caries with climate change. Two studies were linked to SDG 13.2 and they suggested that the practice of pediatric dentistry contributes negatively to environmental degradation. One study provided evidence on caries prevention management strategies in children that can reduce environmental degradation.

The evidence on the links between SDG13 and ECC suggests that climate change may increase the risk for caries, and the management of ECC may increase environmental degradation. However, there are caries prevention strategies that can reduce the negative impact of ECC management on the environment. Context specific and inter-disciplinary research is needed to generate evidence for mitigating the negative bidirectional relationships between SDG13 and ECC.

Peer Review reports

Introduction

Worldwide, the mean temperatures have climbed by approximately 1 °C (1.7 °F) since 1880, with projections indicating a potential warming of around 1.5 degrees Celsius (2.7 °F) by 2050 and a more substantial increase of 2–4 degrees Celsius (3.6–7.2 degrees Fahrenheit) by 2100 [ 1 ]. This alteration holds significance due to the immense heat energy required to elevate the earth’s average annual surface temperature, even by a slight margin, considering the vast extent and heat-retaining capacity of oceans. The approximately 2-degree Fahrenheit (1-degree Celsius) upswing in the global average surface temperature since the pre-industrial period (1880–1900) might appear modest, yet it equates to a substantial accumulation of heat [ 2 ].

Climate change is a huge concern for health, and its impact is felt globally. According to the World Meteorological Organization, greenhouse gas emissions are more than 50% higher now than in 1990 [ 3 ], and the World Health Organization (WHO) reports that global warming is causing long-lasting changes to the climate system that threatens irreversible consequences [ 4 ]. About 91% of geo-physical disasters are climate-related and they have tremendous human impact. Between 1998 and 2017, there were about 1.3 million deaths and 4.4 billion injuries due to the consequences of climate change [ 5 ].

The suggested health effects of climate change include changes in the prevalence and geographical distribution of respiratory diseases [ 6 , 7 ]. Respiratory diseases such as asthma and its medicines increase the risk of caries [ 8 , 9 , 10 ]. The increase in greenhouse gas emissions and global warming are associated with an increase in geophysical disasters [ 11 ]. These disasters result in humanitarian crises [ 12 ] which likely increase the burden of dental disease, including early childhood caries (ECC) [ 13 ]. The emitted gases that deplete the ozone layer include methane and nitrous oxide emissions [ 14 ]. Methane is suggested to have an inverse association, and nitrous oxide has a direct association with global ECC prevalence [ 15 ].

Climate change is also associated with food insecurity, which is linked to caries [ 16 , 17 ]. The risk of ECC may also increase with economic development, industrialization, and urbanization [ 18 , 19 ], a phenomenon associated with increased gas emission and ozone depletion [ 20 ]. On the other hand, climate change also leads to arid conditions and high alkalinity in the ground waters, which promote fluoride release from clay and fluorite-bearing minerals [ 21 , 22 ]. High temperatures promote longer residence times of ground waters, thereby leading to high fluoride contents of the water from water-rock interactions [ 21 , 22 ]. Although fluorides in water are beneficial for dental health leading to reduced risk of ECC, excessive exposure to fluoride can result in severe fluorosis [ 23 ] which increases the risk of caries [ 24 , 25 ].

The plausible link between climate change and ECC makes the Sustainable Development Goal 13 (SDG13) a subject of interest for pediatric dental care. The SDG 13 is focused on preventing and or tackling problems posed by climate change. It acknowledges that climate change is causing a rise in the occurrence and severity of extreme weather events, including floods, heatwaves, droughts, and tropical cyclones. These, in turn, heighten health risks due to damage to vital infrastructure, disruption of essential services like water and sanitation, education, energy, health, and transportation, exacerbation of water management challenges, and a decrease in agricultural output and food security [ 26 , 27 , 28 ]. These micro-, meso- and macro-level effects of climate change may increase the risk of ECC as it may cause disruption in access to preventive and curative care, limited access to health promotion, prevention information and education and increase the impact of food insecurity on ECC [ 29 , 30 ].

A positive impact on ECC control may be linked with efforts at strengthening the resilience and adaptive capacity to climate-related hazards and natural disasters (SDG13.1); improving education, awareness and human and institutional capacity on climate change mitigation, adaptation, impact reduction and early warning (SDG 13.2); and integrating climate change measures into national policies, strategies, and planning (SDG 13.3) [ 26 ]. . Furthermore, incorporating the commitment made by developed-country parties to the United Nations Framework Convention on Climate Change, aimed at addressing the requirements of developing nations (13.A); and promoting mechanisms for raising capacity for effective climate change-related planning and management with focus on marginalized communities among others (SDG 13.B) [ 24 ], could also influence ECC control. This is because the prevalence of ECC is higher in developing countries [ 31 ] and among marginalized communities [ 32 ]. The conceptual framework for the association between climate change and ECC is presented in Fig.  1 .

The aim of this scoping review was to identify the existing evidence on the association between climate change and climate change-related factors (disasters, sustainable management of natural resource, and human security) with ECC.

We conducted a systematic search to identify scientific literature on the association between climate change and ECC. Our scoping review was conducted according to the JBI guidelines for scoping review [ 33 ] and reported in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews guidelines (PRISMA-ScR) [ 34 ].

Research questions

The following questions guided this review: (i) What is the existing evidence on the association between climate change and ECC? and (ii) What are the factors related to climate change (disasters, sustainable management of natural resource, human security) associated with ECC?”

Articles identification

The initial search was conducted on three electronic databases (PubMed, Web of Science and Scopus) in August 2023. The search was performed using the key terms as shown in Appendix 1. Publications from the inception of each database to August 2023 were screened. No protocol was published for this review. Additional search was conducted by reviewing the references of eligible publications and by searching the semantics scholar website.

Selection of articles

Article inclusion was performed in four phases. The first phase was conducted by one reviewer (MET) who conducted the search in the three databases for the information. In the second phase, two reviewers (OA, MOF) screened the titles and abstracts of all identified manuscripts and removed the duplicates. In phase three, two reviewers (OA, MOF) reviewed the full text of the manuscripts independently and compared results to achieve consensus. In addition, and reference lists of potentially relevant publications were manually searched. Lastly, the information generated was shared with two experts for their review (MET and RJS).

Eligibility criteria

Articles were included if they focused on children younger than 6 year of age or if they did not specifically exclude this age group. In addition, studies that identified ECC as dependent or independent factors in relation to climate change or climate change related factors were included. No study design was excluded based on study design. There was no language restriction for the search conducted in the three databases. Language restrictions were introduced at the phase of review of the full texts. Articles not published in English were excluded. We also excluded studies that focused on the prevalence of ECC or on climate change exclusively.

Data charting

Specific information from the included publications was extracted. This includes information on the first author’s name, year of publication, study location, World Health Organization’s region where the study was conducted (African (AFR), Eastern Mediterranean (EMR), European (EUR), Region of the Americas (AMR), South-East Asian (SEAR), and Western Pacific (WPR)) [ 35 ], study design, study objectives, main findings and conclusion on the association between SDG13 and ECC, and whether the article was published in dental or non-dental journal. Information from each publication was compiled and summarized in Table  1 . The summarized data were then shared with two experts (RJS and AA) for their review. Publications were included only when there was a consensus between the experts and the earlier three reviewers. The final consensus document was also shared with members of the Early Childhood Caries Advocacy Group ( www.eccag.org ) to identify any other relevant publication that might not have been retrieved by the original search strategy.

Data analysis

We performed a descriptive analysis of the extracted items. These descriptions encompassed the World Health Organization’s region and countries where the studies were conducted, the study designs employed, the journals (whether dental or non-dental) in which the studies were published, and the findings. Interpretive inductive analyses of the objectives and conclusions of the studies were also conducted. In addition, an analysis was conducted linking the study findings with an SDG13 indicator.

Role of the funding source

The study was funded out-of-pocket. This had no role in the study design, data collection, analysis, decision to publish, or preparation of the manuscript.

Figure  2 shows the process undertaken to identify relevant literature. The initial search of the three databases yielded 113 potential publications. Fifty-seven duplicated papers were removed, leaving 56 papers that underwent title and abstract screening. Of these, 54 papers were excluded leaving only two papers for study inclusion [ 36 , 37 ]. In addition, two publications were identified from search in the semantic scholar website and another two identified by searching the references of one of the studies that met the eligibility criteria [ 36 ]. These additional four papers provided data on potential connections between climate change and caries [ 16 , 38 , 39 , 40 ]. One of the six papers assessed the impact of management of ECC on climate change and ECC [ 37 ]. Table  1 presents further details regarding the six included publications.

Overview of studies

Two of the six retrieved articles were from India (SEAR) [ 36 , 38 ], one was from China (the SEAR) [ 37 ], the US (AMR) [ 16 ], the UK (EUR) [ 39 ] and Japan (WRP) [ 40 ], respectively. The three papers from 2021 to 2023 were published in dental journals [ 16 , 36 , 39 ] while the three older papers were published between 2007 and 2019 in non-dental journals [ 37 , 38 , 40 ]. One paper was an intervention simulation study [ 39 ], two reported findings from archeologic populations [ 37 , 40 ] and three papers that were commentaries/opinions [ 16 , 36 , 38 ].

The study objectives covered a range of topics from highlighting the need for environmentally-friendly solutions within dental practices to mitigate the ecological footprint of dental procedures [ 36 ], to the exploration of how environmental factors like climate may have influenced dental health in ancient populations [ 37 , 40 ], and broader discussions on considerations and adaptation strategies to address the evolving environmental challenges of oral health management and outcomes in the context of global climate disruption [ 16 , 39 ].

The study conclusions highlighted the interconnectedness between climate change, environmental sustainability, subsistence patterns, and oral health outcomes. It highlighted that the use of environmentally harmful dental materials contributes to environmental degradation and climate change [ 36 ]; climate change-induced shifts in subsistence economy, heat and oxidative stress, air quality that can significantly impact oral health outcomes [ 37 ] including increasing the risk for caries [ 16 , 38 , 39 ]. Alternative materials should be explored to mitigate these detrimental effects [ 36 ], and strategic approaches can be adopted to manage the impact of dental caries preventive on the climate [ 39 ].

In addition, the studies were linked to two targets of SDG13: specifically, SDG 13.1, which emphasizes enhancing resilience and adaptive capacity to climate-related hazards and natural disasters globally [ 16 , 37 , 38 , 40 ]; and SDG 13.2, which focuses on integrating climate change measures into national policies, strategies, and planning [ 36 , 39 ]. The four studies linking caries to SDG 13.1 suggests that adaptive measures to climate changes may increase the risk of caries. The two studies linking caries to SDG 13.2 indicate that pediatric dental practices have a negative impact on environmental degradation, consequently contributing adversely to climate change. However, one of the two studies proposes that specific actions can be taken to mitigate the environmental impact of caries prevention practices in children [ 39 ].

This scoping review identified articles that discussed how the discipline of pediatric dentistry’s carbon footprint can contribute to climate change. The studies identified a bi-directional relationship between caries and climate change. First, that adaptive processes for climate change can increase the prevalence of caries. Second, that the management of caries contributes to environmental degradation. Third, that purposeful strategic approaches to caries prevention in children can reduce the detrimental impact of caries management on the environment. These findings support our study hypothesis on the possible links between ECC and climate change.

However, the evidence supporting the study hypothesis are limited to commentaries, suggested archeological evidence and simulation studies. Studies on the impact of climate change are only starting to evolve. Methodological challenges may have limited the investigations into the link between climate change and ECC. Martens and McMichael identified a range of methodologies that could be used for studying the impact of climate change on health [42]. These methodologies are applicable for the study of the impact of climate change on oral health such as the evaluation of the impact of climate changes on shifts in the range and densities of caries predisposing organisms in the oral cavity, and children’s vulnerability to ECC. The current study identified an investigation that used implementation science approach to demonstrate how caries preventive practices in children can reduced the negative impact of dental practice on the environment [ 37 ]. It is therefore feasible to not only conduct studies to provide evidence on the link between ECC and climate change, but to demonstrate how the management of ECC can reduce environmental degradation. More studies are needed to identify context specific management strategies for ECC management that can be brought to scale.

One of the studies suggests a link between heat related climate changes and ECC [ 37 ]. We postulate that this link may result from the warming phenomenon that triggers an increase in water consumption. Existing evidence suggests that variations in water consumption levels between the coldest and warmest periods can fluctuate from 20% to as high as 60% [ 41 ]. Additionally, the intake of fluids per unit of body weight is most pronounced among infants and diminishes with advancing age [ 42 ]. Consequently, there may be a probable cumulative rise in children’s fluoride consumption due to global warming. This stems from multiple sources, including fluoride present in drinking water, fluoride-containing toothpaste, fluoride supplements, infant formula, beverages made with fluoridated water, cow’s milk from animals raised in fluoride-containing environments [ 43 , 44 ], and crops cultivated in soil with elevated fluoride content due to interactions with water and rocks [ 17 , 20 ]. The permissible threshold for fluoride intake is influenced by climatic conditions [ 45 ], with severely elevated fluoride intake, severe fluorosis, and a potential elevated risk of dental caries [ 22 , 23 , 46 ]. Geothermal temperature has been viewed as one cause for high fluoride levels recorded in groundwater (from deep aquifers and geothermal springs) [ 47 ]. On the other hand, Beltrán-Aguilar et al. demonstrated no association between outdoor temperature and the total water consumption of children aged 1 to 10 in the United States. This observation remained consistent even after accounting for age, gender, race/ethnicity, or poverty status [ 48 ]. . We, however, found no study addressing the link between outdoor temperature, consumption of water including fluoridated water and the prevalence of ECC. Future studies are needed to identify the pathophysiological pathways between climate change and ECC risks if there is truly a link.

It is also possible that the oxidative stress associated with climate change, arising from a disparity in the generation of pro-oxidant elements and the presence of antioxidant defenses [ 49 ] may be associated with enamel hypoplasia as highlighted by Temple [ 40 ]. Enamel hypoplasia may result from SOD1-mediated ROS accumulation disruption of normal enamel structure through alternative cervical loop cell proliferation and downregulation of RhoA and ROCK in ameloblasts [ 50 ]. Enamel hypoplasia is associated with an increased in the risk for ECC [ 51 , 52 ].

There are, however, other possible pathophysiological pathways for the increased risk of ECC due to climate change not highlighted in the publications mapped in this scoping review. One plausibility may be linked to global warming that has the potential to induce pronounced aridification [ 53 ]. A temperature increases of 2 degrees Celsius would precipitate further arid conditions in 15% of semi-arid climates, potentially impacting over 25% of the globe [ 54 ]. This intensified aridification historically led to the desiccation of crops and increased dependence on marine resources for sustenance, akin to occurrences around 2000 B.C [ 55 ]. . This shift towards marine food sources is likely to encourage diets lacking in essential nutrients, potentially resulting in an increased rate of new bone formation on the outer surface of bones (periosteal new bone formation) [ 55 ]. However, there is a suggestion that carious lesions, premature tooth loss, and dental enamel hypoplasia might not necessarily experience an upswing due to aridification [ 55 ]. Studies on the pathways to link ECC and climate change are therefore, critically needed, to be able to take collective global actions to mitigate the negative oral health impact climate change may have on children.

Another pathophysiological pathway that may link climate change with an increase in the risk for ECC is the impact of rapid climate shifts on soil composition, solubility, and plant absorption [ 56 ]. These alterations could lead to a notable shift in the concentration of certain trace elements within plants, attributed to heightened translocation, improved photosynthetic capacity, and enhanced growth. Conversely, the warming process might result in reduced trace element concentrations in tubers, indicating that the tuber growth rate surpasses its ability to take in metals at elevated temperatures [ 57 ]. The presence of trace elements in plants contributes to the development of enamel and dentin [ 58 ], although the precise mechanisms governing the integration of trace elements into soils and, subsequently into human teeth require further elucidation [ 59 ]. The plausibleness of these interactions requires further investigations as the current study highlights that the objectives of the accessible studies on ECC and climate change are limited in the scope of their explorations.

In addition, the necessity for studies tailored to specific contexts highlights the limited regional coverage in current research examining the connections between ECC and climate change. Notably, our investigation revealed very few studies on this sub a lack of studies conducted in the AFR and EMR regions. Despite expectations that climate changes will alter rainfall patterns, impacting agriculture and diminishing food security while exacerbating water security issues in Africa [ 60 ], there is a notable absence of corresponding studies. Similarly, anticipated climate changes in the EMR region are expected to result in under-nutrition, respiratory illnesses, mental health issues, allergic reactions, and pulmonary diseases due to dust storms [ 61 ]. Despite being the two-worst impacted region in terms of health consequences resulting from climate change [ 62 ], these regions are currently underrepresented in evidence generation regarding the impact of climate change on health, including oral health. Consequently, significant gaps exist in our awareness and understanding of these links, potentially limiting mitigation and adaptation efforts [ 61 ]. It is, therefore, important to strengthen efforts to generate evidence from all regions with particular attention paid to AFR and EMR.

The suggested pathophysiological pathways for linking ECC and climate change clearing indicates the interconnectedness between climate change, environmental sustainability, subsistence patterns, and oral health outcomes. There is, therefore, the need for interdisciplinary and collaborative studies. One method that can be used to study the link between ECC and climate change is the integrated eco-epidemiologic models to identify the impact of climate change or stratospheric ozone depletion on the profile of organisms that cause caries; the thermal-related impact of climate change on the fluoride content of ground waters and its impact on caries risks; or the impact of ozone depletion on tooth structure and caries risk. These forms of study may present major scientific challenges in conceptualizing and technical difficulty with assessing the oral health impacts of these changes [42]. Eco-epidemiologic models will require a lot more anticipatory thinking and mathematical modelling of potential future impacts, which will be useful for policymakers [ 63 ].

Other study methods include the use of epidemiological surveillance techniques, assessment of the oral health impact of climate change using ecological frameworks, monitoring of the direct oral health impact of seasonal variations, natural disasters, marine ecosystems and ecosystems health, food production and food security, and emerging and resurgent infectious diseases [ 63 ]. Other methods include the use of retrospective study, integrated assessment modelling on oral health, and landscape epidemiology of caries profiles using remote censoring, Geographic Information system and spatial statistics [ 63 ]. The study methodologies, however, need to promote interdisciplinary research adapted for the modelling of complex processes and handling of attendant uncertainties [ 64 ].

The results confirmed the hypothesis regarding the connection between ECC and climate change, and mapping exercise highlighted areas where existing evidence has focused and identified new areas for further research. This is crucial not only for establishing links between ECC and all SDG13 indicators but, more importantly, for identifying ways to mitigate the negative bidirectional relationships between ECC and SDG13. Of interest are the archaeological studies identified in this study [ 37 , 40 ]. These archaeological studies provide valuable insights into the historical and cultural determinants of caries, offering a unique perspective on the complex interplay between environmental, dietary, and sociocultural factors. By incorporating archaeological evidence into research and policy, stakeholders can advance efforts to address ECC and promote oral health within the framework of Sustainable Development Goal 13. Climate change is a major public health concern, and stakeholders need to proactively engage in mitigating the risk of poor oral health associated with poor climate controls using evidence that can be generated through multiple research strategies.

This scoping review, however, has a few limitations. First, our search was restricted to English literature only, potentially resulting in the omission of studies on the correlation between ECC and climate change published in other languages. This language restriction was solely applied during the article selection process for full-text review, ensuring transparency regarding the number of eligible reports available in languages other than English [ 65 ]. The decision to limit our search to English literature was made due to the inability to read and interpret literature written in other languages. Second, our search was limited to three data bases which may have led to the omission of relevant articles not captured by the search strategy, potentially introducing selection bias. The scope of the study is also limited to children under 6 years limiting the generalizability of findings to other age groups. Despite the limitations the study highlights plausible links between ECC and climate change that can be explored empirically in future studies.

In conclusion though there is the plausibility of climate change having an impact on the health of the dentition and the risk for caries. Studies are needed to generate empirical evidence of the impact of climate change on caries risk in children. This will help with the formulation of policies and the design of programs that can help policymakers and decision-makers proactively prevent the increase in the prevalence of ECC as we move into the future. Addressing these complex relationships is essential for developing holistic strategies to promote both environmental sustainability and oral health.
