Milk Production Forecasting by a Neuro-Fuzzy Model

Page: 3-11 (9) Author: Atsalakis S. George, Parasyri G. Maria and Zopounidis D. Constantinos DOI: 10.2174/978160805263911203010003 PDF Price: $15

Many fields are increasingly applying Neuro-fuzzy techniques such as in model identification and forecasting of linear and non-linear systems. This chapter presents a neuro-fuzzy model for forecasting milk production of two producers. The model utilizes a time series of daily data. The milk forecasting model is based on Adaptive Neural Fuzzy Inference System (ANFIS). ANFIS uses a hybrid learning technique that combines the least-squares method and the back propagation gradient descent method to estimate the optimal milk forecast parameters. The results indicate the superiority of ANFIS model when compared with two conventional models: an Autoregressive (AR) and an Autoregressive Moving Average model (ARMA).

The Role of Production Contracts in the Coordination of Agri-Food Chain: Evidence and Future Issues for the Durum Wheat Chain in Italy

Page: 12-22 (11) Author: Davide Viaggi and Giacomo Zanni DOI: 10.2174/978160805263911203010012 PDF Price: $15

The economics of contracts has undergone major developments in the recent decades. At the same time, the issue of co-ordination among actors in the same product chain through contractual instruments has attracted significant attention. In addition, the recent volatility of agricultural prices has made the role of contracts in risk allocation more important across different stages of the production chain. The paper explores the role of production contracts in the co-ordination of agri-food chain, considering evidence from the particular case of the durum wheat chain in Italy. After a review of the literature and brief examination of the sector and institutional context of Italian wheat production, the paper considers the present and potential role of production contracts, through a Delphi exercise. Based on this, proposals for action priorities (policy) are discussed along with an agenda for future research. The outcome of the Delphi exercise confirms the perceived need of improving the use of contracts in the Italian wheat sector. It also confirms the difficulties in addressing this issue. Solutions and needs for further research are identified at two main levels: a) detailed contract design; and b) wider chain governance.

Effects of the European Union Farm Credit Programs on Efficiency and Productivity of the Greek Agricultural Sector: A Stochastic DEA Application

Page: 23-46 (24) Author: Anthony N. Rezitis, Kostas Tsiboukas and Stavros Tsoukalas DOI: 10.2174/978160805263911203010023 PDF Price: $15

This study examines technical efficiency and productivity growth of Greek farms participating in the 1994 European Union Farm Credit Programs (1994-EU-FCP), i.e. regulation 2328/91. In this paper, two farm-level economic data sets are used, i.e. the crop and the livestock data set, where each one consists of two different groups of farms: one group contains farms participating in the 1994-EU-FCP while the other one contains non-participating farms. The data sets are observed over the 1993 and 1997 years. The paper uses the approach developed by Simar and Wilson (1998a, b) to bootstrapping both DEA efficiency measures and Malmquist productivity indices. Furthermore, the present paper uses the Malmquist index decomposition proposed by Simar and Wilson (1998b) and Zofio and Lovell (1997) to investigate the sources of productivity change. The technical efficiency score results indicate that, in terms of the crop oriented farms, the program failed to increase the efficiency of the participated farms even though the most efficient farms entered the 1994-EU-FCP. In contrast, in terms of the livestock oriented farms, the program managed to increase the efficiency of the participated farms though less efficient farms entered the program. The total factor productivity growth results, in terms of crop-oriented farms, show statistically significant decline of productivity for the group of program farms but a statistically significant increase for the group of non-program farms. The total factor productivity growth results, in terms of livestock oriented farms, show a statistically significant increase of productivity for the group of program farms but no change for the group of non-program farms.

Institutional Innovations in the Common Agricultural Policy: A Theoretical Approach based on Legitimacy

Page: 47-56 (10) Author: Melania Salazar-Ordóñez and Gabriel Pérez-Alcalá DOI: 10.2174/978160805263911203010047 PDF Price: $15

The Common Agricultural Policy (CAP) of the European Union (EU) has been highly political and social controversy, within the EU as well as at international level. However, the reforms on the institutional structure have not been frequently analysed. This paper, based on the Institutional Innovation Theory, examines the role of different exogenous and endogenous factors which have been boosted or slowed down, the five CAP reforms. According to these factors we analyse three key issues in the EU general political system, two topics in the EU domestic-economic system and the external pressures. Later, these factors are considered on a theoretical approach applying investment theory and expected utility maximization by means of the net present value model and dependency relations. The main results show that role played by the EU institutional structure is fundamental as a limited factor, and the external pressures and citizen’s acceptance of this policy are an important boost factor.

Agricultural Externalities and Environmental Regulation: The Case of Manure Management and Spreading Land Allocation

Page: 57-69 (13) Author: Isabelle Piot-Lepetit DOI: 10.2174/978160805263911203010057 PDF Price: $15

The aim of this paper is firstly to show how the measures introduced by the European regulation on manure management are incorporated into the theoretical analysis framework for studying the issue of nonpoint externality and especially, agricultural runoff. The model is extended because only some of the polluting emissions at the origin of diffuse pollution are regulated by the Nitrates Directive. More specifically, the model represents the standard that limits the spreading of organic manure to 170 kg/ha as a production right assigned to each farm. Secondly, this paper proposes an empirical model in which the theoretical assumption that productive abilities are fully exploited is relaxed. In order to describe the disparity that exists between individual situations, an empirical model represents the production technology by means of a directional distance function. Finally, the aggregation properties of the directional distance function are used to simulate the practice of looking for off-farm lands as a means of complying with the standard. We look at how land can be allocated among producers in such a way as to combine the disposal of manure in accordance with the limit of the Nitrates Directive with an improvement in the productive and environmental efficiency of all farms. Using a sample of French pig farms, results indicate only a low potential for a reduction in nitrogen pollution based on the reduction in productive inefficiencies and the allocation of spreading lands among farmers in a same area.

Energy Crops Situation in Castile and Leon: Incentives and Barriers to Success

Page: 70-93 (24) Author: Rita Robles and Luigi Vannini DOI: 10.2174/978160805263911203010070 PDF Price: $15

Over the last few years, a number of events have produced deep change in Spanish agriculture. The agreements ensuring from the negotiations within the World Trade Organization (WTO), the new exigencies of the demand for reducing the surpluses of certain food and feed crops (cereals, oil-seeds, sugar beet…) and the Common Agricultural Policy (CAP) expenses, the reform of CAP and the different Common Markets Organizations (CMO’s), along with the vocation to produce (greatly influenced by geo-climatic factors), have led to a deep and long-lasting crisis of the sector in many important agricultural regions in Spain, as is the case in Castile and Leon. This crisis implies depopulation and alteration of the population structure and the rural environment, with subsequent environmental, socio-cultural and territorial consequences. Within this framework, energy crops are one of the scarce local productive orientations which could allow Castile and Leon farmers to produce an output demanded by the markets. This paper examines the current situation and the possibilities of development for this sector, using the Rural Rapid Appraisal (RRA) and Strengths, Weaknesses, Opportunities, Threats (SWOT) methods, in order to identify and assess the profitability of the main energy crops as well as the technical, socio-cultural, political and economic barriers for introducing these crops in the local productive farming sector. The study also provides an evaluation of the last energy and CAP measures and an outlook for future market developments and policy recommendations.

Governing of Agro-Ecosystem Services in Bulgaria

Page: 94-129 (36) Author: Hrabrin Bachev DOI: 10.2174/978160805263911203010094 PDF Price: $15

This paper incorporates interdisciplinary New Institutional and Transaction Costs Economics and analyzes the governance of agro-ecosystem services in Bulgaria. Firstly, it presents a comprehensive framework of analyses of environmental governance including: definition of agroecosystem services and governance; specification of governance needs and spectrum of governing modes (formal and informal institutions, market, private, public and hybrid forms); assessment of efficiency of different modes of governance in terms of their potential to protect diverse eco-rights and investments, assure a socially desirable level of agro-ecosystem services, minimize overall costs, coordinate and stimulate eco-activities, meet individual and social preferences and reconcile conflicts of related agents etc. Secondly, it identifies and assesses the governance of agro-ecosystem services in Bulgaria. It proves that post-communist transition and EU integration brought about significant changes in the state and the governance of agro-ecosystems services. Newly evolved market, private and public governance has led to a significant improvement of the part of agro-ecosystems services introducing modern eco-standards and public support, enhancing environmental stewardship, disintensifying production, recovering landscape and traditional productions, diversifying quality, products and services. At the same time, the novel governance is associated with new challenges such as unsustainable exploitation, lost biodiversity, land degradation, water and air contamination etc. Moreover, it demonstrates that implementation of the EU common policies would have no desired impact on agro-ecosystem services unless special measures are taken to improve management of public programs, extend public support to dominating small-scale and subsistence farms.

Ex Post Liability for Loss vs. Ex Ante Liability Insurance as Solutions to Reversal Risk in Carbon Offset Projects

Page: 130-144 (15) Author: Joshua Anyangah DOI: 10.2174/978160805263911203010130 PDF Price: $15

When included as part of a larger emissions rights trading system, carbon offset projects can automatically achieve a given reduction of emissions in a cost-effective manner. One major concern with this system, however, is the risk of emissions reversal-the deliberate or accidental release of carbon back to the atmosphere long after carbon credits have changed hands. This downside risk may adversely affect the market value of offset credits and undermine the integrity of the carbon trading system. To address this weakness, at least two financial responsibility rules have been proposed. One calls for the imposition of liability, ex post, upon project developers. The other alternative, an ex ante measure, requires that project developers have adequate liability insurance coverage prior to undertaking any offset projects. Taking the view that project developers can control the severity of financial losses arising from reversal and assuming a negligence rule of liability for harm, this paper employs the methods of mechanism design to examine the impact of ex-post liability rules and ex ante liability insurance requirements on incentives to reduce risk. We find that the relative ranking of these two rules crucially depends on the extent of uncertainty regarding the legal standard under liability rules: if uncertainty regarding the legal standard is sufficiently large, then incentives are more pronounced under insurance rules than under liability rules; if the uncertainty regarding the legal standard is sufficiently small, however, then the converse is true.

A Choice Experiments Application in Transport Infrastructure: A Case Study on Travel Time Savings, Accidents and Pollution Reduction

Page: 145-155 (11) Author: Phoebe Koundouri, Yiannis Kountouris and Mavra Stithou DOI: 10.2174/978160805263911203010145 PDF Price: $15

This paper presents the results of a Choice Experiment (CE) conducted to estimate the values derived from a highway construction project in Greece. To account for preference heterogeneity conditional logit with interactions and random parameter logit models are estimated. The results indicate that individuals have significant values for travel time savings, percentage decrease in traffic accidents, percentage decrease in traffic related emissions and landscape modifications. Models where the attributes are interacted with socioeconomic variables perform better and produce lower welfare estimates compared to models without interactions with important implications for cost benefit analysis.

New Perspectives on Agricultural Economics, 2022-2026

The proposed initiative will involve four distinct research projects on different topics in agricultural economics. The topics will be selected each year on the basis of interests of ERS staff and some bearing on emerging or current policy issues. NBER research does not make policy recommendations, but provides background information and analysis that can inform policy decisions.

The proposed topic for the 2023 project is “Assessing the Distributional Impacts of Climate Change in the Agricultural Sector.” Climate change affects all aspects of the agricultural sector, from the production of food and fiber, through the choice of technology by producers, to the set of products that are available to consumers and the prices of those products. USDA is committed to understanding the consequences of climate change, as well as the impact of potential policy responses. Economic research on climate-related issues can advance this mission.

The 2023 project will focus on distributional impacts, because USDA is also committed to promoting equitable outcomes both in the impact of climate-related changes and in the design of policy responses. Doing so requires analysis and measurement of the effects of climate change in the agricultural sector on different groups in the population. These include producers and consumers, households in different income groups, racial and ethnic groups, those who live in different areas, and groups defined along other dimensions.

Agricultural economics research papers/topics, challenges related to beef-cattle pricing between a western block and a third world country.

Abstract: This study considers a business scenario involving three participants. The first participant, in this case the farmer sells the cattle to the second participant, in this case the Botswana Meat Commission (BMC) which, in turn sells the processed beef to the European Union (EU). The BMC offers a price, S1(t), to the farmer for the cattle. The EU offers a price, S2(t), to the BMC. To estimate the parameters spot prices of beef-cattle from the BMC and the EU markets for years 1992 to 2...

Accelerating agricultural productivity to enhance economic growth in Botswana

A climate-adapted push-pull system effectively controls fall armyworm, Spodoptera frugiperda (J E Smith), in maize in East Africa

Abstract: Fall armyworm, Spodoptera frugiperda (J E Smith), an economically important pest native to tropical and subtropical America has recently invaded Africa, causing substantial damage to maize and other crops. We evaluated functionality of a companion cropping system, ‘climate-adapted push-pull’, developed for control of cereal stemborers in drier agro-ecologies, as an added tool for the management of fall armyworm. The technology comprises intercropping maize with drought-tolerant...

Women's empowerment in agriculture and agricultural productivity: Evidence from rural maize farmer households in western Kenya.

Abstract: This paper documents a positive relationship between maize productivity in western Kenya and women’s empowerment in agriculture, measured using indicators derived from the abbreviated version of the Women’s Empowerment in Agriculture Index. Applying a cross-sectional instrumental-variable regression method to a data set of 707 maize farm households from western Kenya, we find that women’s empowerment in agriculture significantly increases maize productivity. Although all indi...

Measuring farm and market level economic impacts of improved maize production technologies in Ethiopia: Evidence from panel data

Abstract: While it is often recognised that agricultural technology adoption decisions areintertwined and best characterised by multivariate models, typical approaches toexamining adoption and impacts of agricultural technology have focused on singletechnology adoption choice and ignored interdependence among technologies. Weexamine farm- and market-level impacts of multiple technology adoption choicesusing comprehensive household survey data collected in 2010/11 and 2012/13 inEthiopia. Econ...

Are individuals willing to pay for community-based eco-friendly malaria vector control strategies?

Abstract: This study was carried out to assess individuals’ willingness to pay (WTP) for UZIMAX, a novel plant-based biopesticide developed for malaria vector control. The biopesticide is estimated to kill up to 100% of Anopheles larvae within 48 h of application and poses no risks to human health and the environment. However, scaling-up of its adoption requires clear evidence of its acceptance by individuals in malaria-prone areas. We conducted Becker-DeGroot-Marschak (BDM) revealed prefe...

Consumer Behavior around Food Safety and Quality in the Context of Technological Innovation

The Impact of Agricultural Insurance on Consumer Food Safety: Empirical Evidence from Provincial-Level Data in China Provisionally Accepted

  • 1 Wuhan University, China
  • 2 Wuhan College, China

The final, formatted version of the article will be published soon.

In the exploration of the efficacy of agricultural subsidy policies, agricultural insurance, as a key element of this policy system, has garnered widespread attention for its potential impact on consumer food safety. This paper delves into the influence of agricultural insurance on the safety of food consumed by individuals, based on provincial panel data in China from 2011 to 2021. The findings indicate that agricultural insurance significantly reduces the incidence of foodborne disease and enhances food safety. Mediating effect tests reveal that agricultural insurance effectively boosts food safety through two key pathways: promoting innovation in agricultural technology and reducing environmental pollution. Moreover, the analysis of moderating effects highlights that increased consumer confidence positively enhances the impact of agricultural insurance. Heterogeneity tests further show that in the provinces with higher levels of agricultural development and stronger government support for agriculture, the role of agricultural insurance in improving food safety is more pronounced. This research not only empirically verifies the effectiveness of agricultural insurance in enhancing food safety but also provides robust theoretical support and practical guidance for the precise formulation and effective implementation of agricultural subsidy policies, particularly agricultural insurance policies, offering significant reference value for policy-makers.

Hybrid intelligence can reconcile biodiversity and agriculture

by University of Hohenheim

Hybrid intelligence can reconcile biodiversity and agriculture

A research team at the University of Hohenheim and Technical University of Munich has developed a new transdisciplinary approach to resolve the tradeoff between biodiversity and agricultural production.

Preserving biodiversity without reducing agricultural productivity: So far, these two goals have not be reconciled because the socio-ecological system of agriculture is highly complex, and the interactions between humans and the environment are difficult to capture using conventional methods.

Thanks to new technology, a research team at the University of Hohenheim in Stuttgart and the Technical University of Munich is showing a promising way to achieve both goals at the same time. The members of the team are focusing on further developing artificial intelligence in combination with collective human judgment: the use of hybrid intelligence. They have published their article in the current issue of Nature Food .

"Although we have more and more data sets at our disposal, we have not yet been able to use them to solve the problem. Available data from remote sensing , proximal sensing and statistical surveys are disconnected and highly fragmented," said Prof. Dr. Thomas Berger, agricultural economist at the University of Hohenheim and lead author of the publication.

"Another challenge is the different planning horizon: Agricultural practices are based on short- and medium-term economic objectives at the field and farm level, that is, on a scale of 1 hectare to 100 hectares. The long-term ecological effects, on the other hand, are evident at the landscape level of 100,000 hectares."

From an ecological point of view, it is therefore necessary to look at the landscape level and better understand the interactions of many farms in terms of space and time. "There is little cross-farm coordination for agri-environmental measures," stated Prof. Dr. Senthold Asseng from the Chair of Digital Agriculture at the Technical University of Munich.

Previous funding programs in agricultural and environmental policy were not designed to enable biodiversity-friendly synergies among farmers, between farmers and other stakeholders, and in science.

The problem is also very challenging from a social science perspective, according to Prof. Dr. Claudia Bieling from the Hohenheim Department of Societal Transition and Agriculture. "This is the classic situation of a social dilemma. Why should individual stakeholders forgo productivity on their own initiative when the common public good of biodiversity conservation benefits many other stakeholders free of charge?"

There are also similar situations that block progress in other economic sectors, e.g., in recycling and waste management as well as in energy and transport.

In order to capture the complexity of the problem and develop new intelligent solutions, joint expertise from the natural and social sciences, engineering, and computer science is required, as well as close cooperation between science and practice.

Technological progress enables new interaction between humans and machines

A 13-person team with precisely this expertise joined forces to develop a transdisciplinary approach—exploiting the new possibilities offered by artificial intelligence in merging and processing large volumes of data. The authors of the publication refer to this combination as "hybrid intelligence."

"By combining the intuitive abilities of humans with the computing power of modern computers and the analytical capabilities of artificial intelligence, for the first time we can develop human-machine systems that successfully address complexity in agriculture," said Prof. Berger.

One component of such systems are computer models with what the team refers to as "multi-agent technology" for the various ecological, social, and economic processes. By enriching these models with artificial intelligence , the research team aims to create a detailed, interactive image of reality in which various biodiversity measures and effects can be simulated and stakeholders can be supported in joint decision-making.

Group payments as a practical example of hybrid intelligence

The authors explain practical implementations in several applied examples, e.g., compensation payments to groups of farmers instead of individual farms.

"The EU provides various subsidies for species protection measures, for example by giving farmers money to set up flower strips," stated Prof. Asseng. "Up to now, farmers have planted the flower strips on their own and without coordinating with their neighbors. Overall, the flower strips are fragmented and have limited effectiveness."

Group payment programs for farmers who coordinate their flower strips at the landscape level with the use of hybrid intelligence are more promising.

In a first step, hybrid intelligence could analyze complex data on soil conditions , local biodiversity, and similar factors and thus identify the locations where cross-farm environmental measures would be particularly effective and crop losses as lowest as possible.

In a second step, AI systems could provide communication platforms that facilitate exchanging information and planning joint projects without excessive bureaucracy. "Another goal would be a fair balance among all parties involved, for example, through new auction mechanisms for subsidies," said Prof. Berger.

The virtual image of their economic and ecological environment would give actors from agriculture, consulting, and politics the opportunity to try out the measures before deciding whether to implement them. "This would make it easier to assess the impact on biodiversity and crop yields and minimize the costs for everyone involved," added Prof. Bieling.

Above all, AI could serve as an automated moderator that follows the discussions within the group and improves decision-making by contributing information or alternative perspectives. "We can currently see the capabilities of generative AI in language processing and generating new content with ChatGPT. This can be particularly useful to ensure that all relevant information is considered in group discussions and creative solutions are found," explained Prof. Dr. Henner Gimpel from the Department of Digital Management at the University of Hohenheim.

Trust and transparency remain crucial for success

If the approach is to be successful, it must be transparent and participatory. "The technology must be designed in such a way that people can trust it. The ethical use of the technology is also crucial," said Prof. Gimpel. Only if these conditions are met can hybrid intelligence systems develop their full potential and find broad acceptance.

According to Prof. Berger, hybrid intelligence holds the key to solving some of the most pressing issues in agriculture. "The prospects are very promising, but there is still a need for fundamental research in order to successfully develop this technology further and then implement it. To achieve this, we need the cooperation of all stakeholders from science, practice, and society."

Diagnostic Study- How to incentivize for private sector involvement in NDC implementation

final_report_conducting_diagnostic_study_on_private_sector_engagement_in_the_implementation_of_ndc.pdf

April 16, 2024

Private sectors had been engaged in investments in Ethiopia since late 1880s when the royal family members and foreign investors invested in the manufacturing and production areas in key economic sectors, namely in transport, hotel & tourism, industry, agriculture, forests. Examples of such earlier investment initiatives include: Ethio-Djibouti Railway (1894 – 1917), Tayitu Hotel (1898), Wood processing Sawmill at the Mengaesha –Suba forest (1905), Dire-Dawa Cement  (1936).  Since then, the government’s development policies developed by the various government systems generally do anchor at the overall approach to economic growth focusing on capital accumulation in the industry, construction, infrastructure sectors and creation of large scale commercial farms in the agriculture sector to feed the growing urban population, generate export earnings and provide agricultural inputs to the industry. 

However, the landscape of private investment in various economic sectors was hampered by economic and political police reforms, popular upheavals, climate related risks. This attributed to stagnated contribution of the private sector to GDP, as demonstrated by the private sector contribution below 5% of the GDP over a century; and it is very recently that the private sectors’ contributions to the national economy approaches to reach close to 20% of the GDP. 

The participants of the diagnostic study (FGDs and KIIs) from private and public sectors and funding agencies identified key investment barriers.
