In many Sub-Saharan countries, farmers cannot meet the growing urban demand for higher quality products, leading to increasing dependency on imports. While the literature has focused on production-side constraints to enhancing smallholder farmers’ output quality, there is scarce evidence of market-side constraints. Using a unique sample of 60 wheat markets in Ethiopia, I examine the relationship between the price obtained by farmers and the quality supplied. Using objective and precise measures of observable (impurity content) and unobservable (flour extraction rate and moisture level) quality attributes, no evidence was found of a strong correlation between the two, suggesting that observable attributes cannot serve as proxies for unobservable ones. Transaction prices further reflect this, indicating that, markets only reward quality attributes that are observable at no cost. However, these results hide cross-market heterogeneity. Observable quality attributes are better rewarded in larger and more competitive markets, while unobservable attributes are rewarded in the presence of grain millers and/or farmer cooperatives on the market site. Both regression and machine learning approaches support these findings.

Adoption of quality-enhancing technologies is often driven largely by farmers’ expected returns from these technologies. Without proper grades, standards, and certification systems, however, farmers may remain uncertain about the actual financial return associated with their quality-enhancing investments. This report summarizes the outcomes of a short video-based randomized training intervention on wheat quality measurement and collective marketing among 15,000 wheat farmers in Ethiopia. Our results suggest that the intervention led to significant changes in farmers’ commercialization behaviors—namely, it prompted farmers to adopt behaviors geared toward assessing their wheat’s quality using easily implementable test-weight measures, assessing the accuracy of the equipment used by buyers in their kebeles (scales, in particular), and contacting more than one buyer before concluding a sale. The training also led to improvements in share of output sold, price received, and collective marketing, albeit with important limitations. First, farmers who measured their wheat quality received a higher price, but only if their wheat was of higher quality. Second, farmers who found that their wheat was of higher quality were more reluctant to aggregate their wheat (that is, sell their products through local cooperatives) than those who found that their wheat was of lower quality. Lastly, the training intervention led to better use of fertilizer in the following season. Our discovery that a short training intervention can significantly change farmers’ marketing and production behavior should encourage the development of further interventions aimed at enhancing farmers’ adoption of improved technologies and commercialization.

Modern marketing arrangements are increasingly being implemented to assure improved food quality and safety. However, it is not well known how these modern marketing arrangements perform in early stages of roll-out. We study this issue in the case of rural-urban milk value chains in Ethiopia, where modern processing companies – selling branded pasteurized milk – and modern retail have expanded rapidly in recent years. We find overall that the adoption levels of hygienic practices and practices leading to safer milk by dairy producers in Ethiopia are low and that there are no significant differences between traditional and modern milk value chains. While suppliers to modern processing companies are associated with more formal milk testing, they do not obtain price premiums for the adoption of improved practices nor do they obtain higher prices overall. Rewards to suppliers by modern processing companies are mostly done through non-price mechanisms. At the urban retail level, we surprisingly find that there are no price differences between branded pasteurized and raw milk and that modern retailers sell pasteurized milk at lower prices, ceteris paribus. Modern value chains to better reward hygiene and food safety in these settings are therefore called for.

In this paper, we test the impact of a simulated market premium for food safety, and of bundling rainfall insurance with an aflatoxin-reducing technology (Aflasafe KE01), on smallholder farmers’ adoption of this technology. To identify these impacts, we conducted a randomized trial through which farmers in one of the most aflatoxin-affected regions in the world were given the opportunity to purchase Aflasafe under experimentally varied market conditions. Half of 152 pre-existing producer groups were assigned to a market linkage treatment and offered a premium price for the maize they aggregated if it conformed to the East African aflatoxin standard. The market linkage treatment was cross-cut with a bundled insurance treatment, in which Aflasafe could only be purchased together with an actuarily fair rainfall index insurance product designed to insure against maize losses due to unfavorable weather conditions during the growing period. Farmers not assigned to the bundled insurance treatment who purchased Aflasafe were able to purchase the same insurance separately.

Debates about public expenditure in the agricultural sector have reopened in many developing and emerging economies because of high budget deficits and changes in public opinion. As a result, agricultural policy in many of these countries is beginning to take a more market-oriented approach to agrarian problems, most notably through the introduction of contract farming. This book explores the policy issues around contract farming and its transformative potential and addresses the lack of empirical research on this topic by focusing on South Asia: principally India, Bangladesh and Nepal. The book first addresses the effects of contract farming (vertical coordination) on productivity, food security indicators (yield, consumption expenditures, prices), employment and input usage. Then it draws lessons from the South Asian case studies on the impact of institutional changes, like contract farming, on income and food security of smallholder households. The core of the book includes case study chapters on several commodities that are produced under contract farming, including vegetables and fisheries in Bangladesh, low-value crops in Nepal and coffee in India. Other chapters also explore contracts, storage, input usage and technical efficiency in these cases. This book serves as an essential guide to academics, researchers, students, legislative liaisons and think tank groups interested in agrarian issues, agricultural economics and agricultural policy in emerging economies and particularly in South Asia.

Evidence continues to mount that foodborne illness imposes a staggering health burden in developing countries. However, standard approaches used by developed country governments to ensure food safety are not appropriate in settings where regulatory enforcement capacity is weak and most firms are small and informal. Thus, interventions to improve food safety in developing countries must take into account the constraints and incentives faced by producers in these countries. In this paper, we test the impact of two such interventions: subsidies for technologies that improve food safety and price premiums for safer produce. We examine the case of on-farm control of aflatoxin, a carcinogenic toxin linked to child stunting that is produced by a fungus commonly found on maize and groundnut. We show that compared to Kenyan farmers who produce maize only for their family’s own consumption, Kenyan farmers who produce maize for sale are less likely to undertake post-harvest practices that increase the unobservable quality of aflatoxin safety. Employing randomized discount vouchers, we find that willingness to pay for a new post-harvest technology to prevent aflatoxin contamination is significantly lower among market producers than subsistence farmers. However, we find that take-up of the technology among market producers increases when they have the opportunity to sell aflatoxin-safe maize at a premium a few months after harvest. Using take-up rates from the experiment, we model the impacts of public subsidies and market incentives for aflatoxin control. We find that subsidization of aflatoxin control technologies is a cost-effective strategy for reducing liver cancer and possibly also for reducing stunting in children. The most cost-effective technologies considered are widely adopted by both subsistence and market producers, implying little additional impact of a price premium on food safety.

While agricultural value chains are rapidly evolving (Reardon, 2015; Reardon et al., 2021; Barrett et al., 2022), research attention has increasingly taken notice of the important role played by actors in the ag ricultural midstream. The agricultural midstream consists of activities that take place after production but before final sale to consumers, with existing literature highlighting transportation, trading/wholesaling, processing/packaging, and storage as key activities (Reardon, 2015; Ambler et al., 2022a). However, even as research on the agricultural midstream has been growing, little is known about the poten tial financial needs or capabilities of midstream actors (Ambler et al., 2022a; Bellemare et al., 2021; Reardon and Minten, 2021). If midstream actors face meaningful financial constraints in growing their businesses, it can hinder employment opportunities, increase consumer food prices, depress agricul tural producer prices, or constrain growth more broadly.

Food has, for most of our species history, been intensely political: who gets to eat what, how often, and through what means? The scale of polity in question has shifted over time, from very local institutions dividing up grain piles to an international community imagined in the Millennium Development Goals of the United Nations. Simultaneously, the numbers and interests of people asserting political stakes in food and agriculture have likewise shifted up and out. Global networks advocate social justice in distal agrarian systems, promotion of some farming techniques and prohibition of others, food sovereignty or efficiencies of markets and trade. Political consumerism allows the well-endowed to "vote with their dollars" for changes in food systems far from home, but depends on certification and labeling from unseen institutions. As an object of governmentality, food has never been so prominent. The thirty-five handbook chapters confront four major themes in the politics of food: property, technology, justice and knowledge. Ronald Herring's editorial introduction asks how food is political, highlighting contention around the role of market, state and information in societal decisions. The first section of the handbook then examines technology, science and knowledge in food production. What is known - and disputed - about malnutrition, poverty and food security? The second section addresses ethics, rights and distributive justice: agrarian reform, gender inequality, entitlements and subsidies, and the social vision of the alternative food movement. The third section looks to intersections of agriculture and nature: wild foods, livestock, agro-ecological approaches to sustainability, and climate change and genetic engineering. The fourth section addresses food values and culture: political consumerism, labeling and certification, the science and cultural politics of food safety, values driving regulation of genetically modified foods and potential coexistence of GMOs, and organic and conventional crops. The fifth and final section looks at frontiers of global contentions: rival transnational advocacy networks, social movements for organic farming, the who and why of international land grabbing, junctures of cosmopolitan and local food narratives, the "supermarket revolution" and the international agrifood industry in low-income countries, and politics of knowledge in agricultural futures.

Modern cooling technologies that utilize renewable energy sources have been increasingly recognized as a promising tool to address a multitude of challenges emerging in progressively complex food systems in developing countries. When provided as cold-storages inside horticulture markets, cooling technologies can potentially contribute to improved quality of products and strengthened vertical linkages. Knowledge gaps about the actual impacts of these technologies in developing countries remain, especially in Africa south of Sahara (SSA). This study partly fills this knowledge gap by providing evidence from the evaluation of recent interventions in northeast Nigeria in which 7 small solar-powered cold-storages were installed across 7 horticulture markets. Combinations of difference-in-difference and variants of propensity-score-based methods suggest that using cold-storages significantly increased horticulture sales volumes and revenues of market-agents. Back-of-the-envelope calculations indicate that increased net revenues for market-agents may be sufficiently large to recoup the investments and operating costs of cold-storages within a reasonable time frame. Using cold-storage also reduced the share of food loss and lengthened the products' shelf-life, while raised prices received by both market-agents and farmers, which were associated with improved product quality, expanded value-adding activities by market-agents, and increased use of advance payments. We find no evidence of negative spillover effects inside horticulture markets. Finally, additional food-science experiments confirm that cold-storages preserve original physical and nutritional qualities of key horticultural products several days longer than products stored under ambient temperature.

From a country plagued with chronic food shortage, the Green Revolution turned India into a food-grain self-sufficient nation within the decade of 1968-1978. By contrast, the decade of 1995-2005 witnessed a spate in suicides among farmers in many parts of the country. These tragic incidents were symptomatic of the severe stress and strain that the agriculture sector had meanwhile accumulated. The book recounts how the high achievements of the Green Revolution had overgrown to a state of this ‘agrarian crisis’. In the process, it also brings to fore the underlying resilience and innovativeness in the sector which enabled it not just to survive through the crisis but to evolve and revive out of it. The need of the hour is to create an environment that will enable the sector to acquire the robustness to contend with the challenges of lifting levels of farm income and coping with Climate Change. To this end, a multi-pronged intervention strategy has been suggested. Reviving public investment in irrigation, tuning agrarian institutions to the changed context, strengthening of market institution for better farm-market linkage and financial access of farmers, and preparing the ground for ushering in technological innovations should form the major components of this policy paradigm.

Unlike physical losses, deterioration of food safety can be difficult to observe. In low- and middle- income countries, much of the food supply is never tested for safety hazards. We analyze data from 1500 maize samples and associated consumer surveys collected from clients of small-scale hammer mills in rural Kenya. We find that while visible damage to maize is penalized by lower prices, there is no correlation between price and aflatoxin, a carcinogenic fungal contaminant, implying an absence of market incentives to manage this aspect of food loss. Aflatoxin contamination is, however, correlated with consumer perceptions of quality, especially for self-produced maize, suggesting an information asymmetry that could lead to inefficiencies in this market.

Food safety hazards threaten the health and market access of smallholder farming households. Smallholders face a number of barriers to improving food safety and quality, including low awareness, high input costs, and the failure of premium prices to pass through to producers. In this paper we examine how lifting these barriers affects Ghanaian groundnut farmers’ adoption of low-tech, low-cost post-harvest practices that reduce aflatoxin contamination. We conduct a randomized controlled trial in northern Ghana over the course of two seasons to test three interventions: (1) training on aflatoxin and its prevention, (2) distribution of free drying sheets, and (3) a price premium for groundnuts that comply with local aflatoxin regulations. In the first year we test for effects on post-harvest practices and aflatoxin levels, and in the second we test for effects on aflatoxin levels only. We find that training farmers substantially improves post-harvest practices. Drying sheet distribution and to a lesser extent the premium price lead to further improvements. We find substantial corresponding decreases in aflatoxin levels from drying sheet provision in the study region where background aflatoxin levels were highest. Beyond regional differences, benefits are higher for households with higher aflatoxin at baseline, more members, and young children. The estimated impacts of the price premium intervention are of similar magnitude, but not statistically significant.
