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.

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.

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.

Recently, issues related to the (perceived) quality of inputs and technologies have been proposed as an important constraint to their adoption by smallholder farmers in low income countries. Taking maize seed embodying genetic gain as a case, we train random agro-dealers to test whether under-adoption by farmers is caused by low quality due to sellers' lack of knowledge about proper storage and handling. In a second hypothesis, we randomly introduce an information clearinghouse similar to popular crowd-sourced review platforms such as yelp.com or trustpilot.com to test whether information asymmetries crowd out quality seed. We find that the information clearinghouse treatment improves outcomes for both agro-dealers and farmers, with agro-dealers receiving more customers and reporting higher revenues from maize seed sales, and farmers reporting significantly higher use of improved maize seed varieties obtained from agro-dealers, leading to higher maize productivity after two seasons. The primary mechanisms behind this impact appear to be an increased effort to signal quality by agro-dealers and a general restoration of trust in the market for improved seed. The agro-dealer training does not have a clear impact on agro-dealers, nor on farmers in associated catchment areas. However, we do find that the information clearinghouse increases agro-dealer knowledge about proper seed storage and handling. Upon exploring interaction effects between the training and the clearinghouse treatment, we also find that the training becomes effective for agro-dealers that are also in the clearinghouse treatment group. This underscores the importance of incentives to make supply side interventions such as trainings effective.

On top of a decade of exacerbated disaster loss, exceptional global heat, retreating ice and rising sea levels, humanity and our food security face a range of new and unprecedented hazards, such as megafires, extreme weather events, desert locust swarms of magnitudes previously unseen, and the COVID-19 pandemic. Agriculture underpins the livelihoods of over 2.5 billion people – most of them in low-income developing countries – and remains a key driver of development. At no other point in history has agriculture been faced with such an array of familiar and unfamiliar risks, interacting in a hyperconnected world and a precipitously changing landscape. And agriculture continues to absorb a disproportionate share of the damage and loss wrought by disasters. Their growing frequency and intensity, along with the systemic nature of risk, are upending people’s lives, devastating livelihoods, and jeopardizing our entire food system. This report makes a powerful case for investing in resilience and disaster risk reduction – especially data gathering and analysis for evidence informed action – to ensure agriculture’s crucial role in achieving the future we want.

The COVID-19 pandemic exposed the vulnerability of agrifood systems to shocks and stresses and led to increased global food insecurity and malnutrition. Action is needed to make agrifood systems more resilient, efficient, sustainable and inclusive. The State of Food and Agriculture 2021 presents country-level indicators of the resilience of agrifood systems. The indicators measure the robustness of primary production and food availability, as well as physical and economic access to food. They can thus help assess the capacity of national agrifood systems to absorb shocks and stresses, a key aspect of resilience. The report analyses the vulnerabilities of food supply chains and how rural households cope with risks and shocks. It discusses options to minimize trade-offs that building resilience may have with efficiency and inclusivity. The aim is to offer guidance on policies to enhance food supply chain resilience, support livelihoods in the agrifood system and, in the face of disruption, ensure sustainable access to sufficient, safe and nutritious food to all.
