To fully benefit from new agricultural technologies like improved seed varieties, significant investment in complementary inputs such as fertilizers and pesticides, and practices such as systematic planting, irrigation, and weeding are also required. Farmers may fail to recognize the importance of these complements, leading to unsatisfactory crop yields and outputs and, eventually, dis-adoption of the variety. We provide a simple model of biased expectations, complementary input use and technology adoption and test its predictions using a field experiment among smallholder maize farmers in eastern Uganda. We find that pointing out the importance of complementary investments using a short, engaging video effectively deters some farmers from using commercial improved varieties. Consistent with the theoretical model, we find some evidence that this behavior change emanates from increased knowledge and expectations that are more in line with realized outcomes. status: Published online

Seed systems for vegetatively propagated crops (VPCs) are frequently governed by regulatory blueprints designed for major cereal crops. This approach tends to disregard the distinct biological char...

Weather-related production risks remain one of the most serious constraints to agricultural production in much of the developing world. Financial and technological innovations that mitigate these risks have the potential to greatly benefit farmers in areas prone to such risks. In this study we examine farmers’ preferences for two distinct tools that allow them to manage drought risk: weather index insurance and a recently released drought-tolerant rice variety. We illustrate how these tools can independently address drought risk and demonstrate the potential for these tools to be combined in a complementary risk management product. Using a discrete choice experiment, we assess farmers’ preferences for these two tools independently and in a bundled package. Findings indicate that farmers are generally unwilling to pay for drought-tolerant rice independent of insurance, largely due to the yield penalty under normal conditions. When bundled with insurance, however, farmers’ valuation of the rice increases. Farmers value insurance on its own, but even more so when bundled with the drought-tolerant rice variety. The results provide evidence that farmers value the complementarities inherent in a well-calibrated bundle of risk management tools.

Agricultural advisory services generally rely on interpersonal knowledge transfers by agricultural extension agents who visit farmers to provide information. This approach is not always effective and has proved hard to scale sustainably, particularly in highly dispersed smallholder farming systems. Information and communication technologies (ICTs) have been advanced as a promising way to overcome many of the problems associated with conventional agricultural extension. We evaluate the effectiveness of an ICT-mediated approach to deliver agricultural information in afield experiment conducted among small-scale maize farmers in eastern Uganda. Three complementary technologies designed to address both informational and behavioral constraints to technical change are considered. First, we investigate the effectiveness of audiovisual messages (video) as a means of delivering information on input use and improved maize management practices to farmers. Second, we quantify the additional impact of complementing video with an interactive voice response (IVR) service. Third, we estimate the incremental effect of time-sensitive short message services (SMS) messages designed to remind farmers about applying key practices at specific points during the season. We find that households that were shown a short video on how to become better maize farmers were performing significantly better on a knowledge test, more likely to apply recommended practices, and more likely to use fertilizer than households that did not view the video. These same households also reported maize yields about 10.5% higher than those that did not view the video. We find little evidence of an incremental effect of the IVR service or SMS reminders. ispartof: American Journal Of Agricultural Economics vol:103 issue:1 pages:317-337 status: published

With new possibilities offered by information and communications technology (ICT), an abundance of products, services, and projects has emerged with the promise of revitalizing agricultural extension in developing countries. However, a growing body of evidence suggests that not all ICT-enabled extension approaches are equally effective in improving adoption, productivity, income, or welfare outcomes. In this review, we explore various conceptual and methodological threads in the literature on ICT-enabled extension in developing countries. We examine the role of multiple impact pathways, highlighting how ICTs influence behaviors and preferences,gender and intrahousehold dynamics, spillovers, and public worker incentives. We also explore the opportunities presented by ICT-enabled extension for increasing the methodological rigor with which extension outcomes are identified. These conceptual and methodological insights—coupled with empirical evidence from prior studies—offer direction for several lines of policy-relevant research on ICT-enabled extension.

To gain a better understanding of intrahousehold bargaining processes, surveys increasingly collect data from co-heads individually. Answers provided by spouses on the same set of questions often differ substantially, alternately attributed to measurement error, poor framing within the cultural context that leads to systematic biases, or other common challenges associated with surveys. However, recent studies suggest that differences in responses from co-heads may also be caused by spouses strategically hiding information from each other. Using detailed data on a large sample of monogamous smallholder maize-farming households in eastern Uganda, we document response patterns from household co-heads related to decision-making, labor time, and sales of farm output. We ask each spouse questions about themselves, but also about their spouse, and compare responses. We also implement two interventions to test if such spousal disagreement in reporting can be reduced by increasing cooperation between spouses and reducing information asymmetries.

In many developing countries, smallholder farmers cultivating vegetatively propagated crops (VPCs) have limited access to quality planting material. This constraint can limit both the yield of and returns on VPC cultivation. Yet policy and regulatory initiatives designed to strengthen access to quality VPC planting materials have been relatively unsuccessful to date. Part of the problem is the unique biological and economic characteristics of vegetative propagation and its distinctness from cereal crops, which dominate narratives on seed system reforms. Drawing on qualitative analysis of policy and practice, this study examines reform options related to quality assurance regulations in four crop-country combinations: cassava in Nigeria and Vietnam, and potato in Kenya and Vietnam. The study highlights theory and evidence on existing models of regulation; alternative models that may better incentivize cost-effective multiplication and distribution; and recommendations for policy, regulation, and investment in VPC seed markets. Findings indicate that regulations designed around strict and centralized quality control systems tend to limit market size, while more localized production systems are limited by both capacity and reach. These findings suggest the need for alternatives that balance a permissive regulatory regime with decentralized production systems, grassroots capacity development, market surveillance, and systems that integrate internal (producer-level) quality assurance with external (regulatory) quality assurance.

With policy measures imposed by governments around the world to contain and prevent the spread of COVID 19, global and domestic economic activities and trade flows have been interrupted. The unexpected shocks of COVID 19 negatively affect not only Myanmar’s economy, but also the livelihoods of Myanmar households. This Working Paper assesses such impacts at the household level using a microsimulation model based on the Myanmar Poverty and Living Conditions Survey (MPLCS) conducted in 2015.

It is widely recognized that local management of common pool resources can be more efficient and more effective than private markets or top-down government management, especially in remote rural communities in which the institutions necessary for the enforcement of centrally-imposed regulations may be weak or prone to elite capture. In this paper, we explore the propensity for cooperation in the management of local common resources by introducing a variant of a public goods game among remote rural communities in the state of Odisha, in eastern India. We explore various patterns of cooperation, including free riding behavior, unconditional cooperation (altruism), and conditional cooperation, in which individuals' propensity toward cooperation is tied to their beliefs about the level of cooperation among their peers. We find that a significant portion of our sample fall into this latter category, but also that their expectations about the level of contributions among their peers is somewhat malleable, and beneficial activities from external actors such as NGOs can foster increased social cohesion which increases both the level of these expectations and the manner in which these expectations are translated into subsequent cooperative behavior. We also find that cooperation is somewhat fragile, with group heterogeneity and risk in the returns to cooperative behavior posing a threat to the stability of the cooperative system.

In many developing countries, agricultural extension services are generally biased towards men, with information targeted mainly to male members of a farming household and in formats that are rarely tailored to female members. Nevertheless, female farmers may also benefit from such services as this may affect their ability to make informed decisions, resulting in increased farm productivity, household income, and welfare. We conduct a gendered field experiment among maize-farming households in eastern Uganda to test whether video-enabled extension messaging affects outcomes related to maize cultivation. In this experiment, men, women, and couples are shown randomly assigned videos about improved maize management practices in which male, female, or both male and female actors are featured. We first vary exposure to the videos by gender to test the effects of changes in intra-household information asymmetries, investigating whether involving women as recipients of information increases their ability to participate in household decision-making, and thus their involvement in household production choices. We then vary exposure to the gender of the actors in the videos to test for role-model effects, exploring whether involving women as information messengers challenges the idea that decision-making is a predominantly male domain, in turn affecting women’s outcomes. Results show that targeting women with information increases their knowledge about improved maize management practices, their role in agricultural decision-making, the adoption of recommended practices and inputs, production-related outcomes, and the quantity of maize women sell to the market. Results for the role-model effects are mixed, and are evident more in joint household outcomes than individual women’s outcomes. Overall, our findings suggest that in the context of our study, extension efforts aimed at directly addressing intra-household information asymmetries may be a first-best means of empowering women in agriculture. Other, more subtle means that seek to influence perceptions and norms about gendered roles in the household may not generate expected effects or work via expected impact pathways, though they remain worth further exploration.

In many African countries south of the Sahara, farmers depend on the cultivation of vegetatively propagated crops (VPCs) for both consumption and commercial purposes. Yet yields for these crops remain at low levels due, in part, to the persistent use of low-quality planting material. Efforts to improve the quality of planting material exchanged in markets or through other channels are often hampered by the unique biological and economic characteristics of vegetative propagation—characteristics that distinguish VPCs from the major cereal crops that drive and shape the policy and investment choices made in many of these countries. This suggests that continued investment in new technologies and systems to produce, package, and distribute VPC planting materials will require customized policies and policy support if these systems are to supply farmers with quality planting material at any significant and sustained scale. This paper explores these issues in the context of the cassava seed system in Nigeria by drawing on (1) prior research, public policy documents, and government statistics; (2) key informant interviews and focus group discussions with seed system actors; and (3) a unique dataset from the 2015 Cassava Monitoring Survey of Nigeria (CMS). The paper examines the production and supply of cassava planting material, the influence of various quality assurance systems on production and supply, and the implications for smallholder farmers in Nigeria. We describe the market, non-market, and regulatory systems that shape the cassava seed market in Nigeria, focusing on effectiveness, influence, and reach. We then explore the ground realities—how farmers actually acquire and use cassava planting material—given the (weak) state of markets and regulation. This is followed by a discussion of alternative policy and regulatory approaches to managing and expanding the cassava seed system, emphasizing a more decentralized approach that prioritizes investment in innovative capacity at the community and enterprise levels.

Can stronger political competition improve rural livelihoods in developing countries? We explore this question in rural Pakistan, showing that greater political competition in a Provincial Assembly (PA) constituency predicts significantly better access to publicly-provided infrastructure and amenities, but no changes in other public goods including perceived access to justice and security. Nonetheless, overall welfare effects appear to be positive: higher political competition predicts higher expenditures per capita, especially among land-poor households. It also predicts higher land values, greater land wealth, and lower land wealth inequality. Further, political competition increases land rental, possibly indicating improved functionality of land markets. Sensitivity analyses suggest that our estimates are unlikely to be substantially affected by omitted variable bias, and they are further similar to instrumental variables estimates. The findings are also robust to use of alternate measures of political competition. Greater provision of both public and private goods appears to explain welfare improvements.

With heterogeneous demand and consumption externalities, market segmentation and targeting can improve social welfare. We use a selective trial for laser land leveling (LLL) in India to understand such targeting strategies. We elicit farmer demand for and benefits from LLL services. LLL reduces groundwater extraction by 24%, with comparable fuel savings from reduced pumping. To leverage positive externalities, we combine farmer demand, LLL pumping effects, and service provider costs to evaluate the cost-effectiveness and other impacts of potential targeting strategies. A first-hour LLL discount—a second-degree price discrimination strategy—emerges as the most cost-effective targeting strategy for reducing groundwater extraction.

During the past two decades, a series of global policy changes affecting genetic resource conservation, use, and exchange have entered into force: the 2004 International Treaty on Plant Genetic Resources for Food and Agriculture (ITPGRFA), and more recently, the 2014 Nagoya Protocol on Access and Benefit Sharing (NP), a follow-on to the 1993 Convention on Biological Diversity (CBD). This paper characterizes the changing policy landscape governing international exchanges of plant genetic resources for food and agriculture (PGRFA). Emphasis is placed on understanding how global and national policy changes associated with the CBD and ITPGRFA are significantly associated with the movement of genetic resources to draw lessons about the potential effects of the NP. We examine crop-specific historical trends in genebank acquisitions, changes in germplasm exchange networks over time, and correlates of such exchanges for seven crops that are important to food security in many developing countries. We observe sharp declines in genebank acquisitions in 1993 (when the CBD came into effect) followed by reductions in germplasm exchange network sizes. These trends and patterns change after 2004 (when the ITPGRFA came into effect), but only for some crops. We also find that a country’s membership in the CBD is closely associated with reductions in genetic resource flows, while ITPGRFA membership has an opposite association. Despite important crop and country variations, results suggest the considerable influence of both the CBD and ITPGRFA, further suggesting that the NP may affect global PGRFA flows in a potentially negative and unintended manner.

Agricultural extension and advisory services are critical to supporting technological and institutional changes that can improve the livelihoods of small-scale farmers in developing countries. However, many extension services are under-resourced, out of date, and need of structural and content changes. However, efforts to systematically strengthen local extension systems often fall into the trap of promoting blueprints that are insufficiently adapted to local context. To that end, researchers developed the best-fit framework in the 2000s to provide impetus for pursuit of more locally-tailored extension solutions. Today, almost a decade later, researchers test the framework under real-world conditions in a cross-country application. This paper examines the application of this framework across six dimensions and seven countries to formulate a set of best-fit recommendations that are also broadly appreciable. The findings show that it is possible to apply the framework to the analysis of EAS across countries while also maintaining a very localized perspective on recommendations. Across the seven countries, certain obvious commonalities exist: The growth in pluralism in extension providers, the persistence of weak incentives for extension agents, and the lack of enabling policies. At the same time, innovative solutions to many of the challenges held in common—ICT-enabled extension, performance incentives, and value-chain oriented extension—are heterogeneous. The framework allows users to pursue change processes in EAS in response to their own local realities.

Agronomic analyses of new technologies are often conducted under carefully controlled research station programs or trials managed by self-selected farmers. Oftentimes, the technologies are then scaled up with minimal evaluation under real-world conditions. Yet, the interim step between agronomic trials and large-scale promotion is crucial to generate evidence on the social and economic impact of technologies that is both internally valid and generalizable. The article focuses on a participatory action research program in Malawi designed to test and identify scalable technology options to intensify the smallholder sector and contribute to poverty reduction and food and nutrition security. We examine the socioeconomic characteristics of farmers testing technologies and find evidence of systematic targeting of better-endowed farmers. After controlling for observable differences using matching and a doubly robust estimator, we find evidence of early positive effects on maize yield and harvest value, although placebo tests suggest possible selection on unobservables. We note that attention should be given to program design and household characterization to better define and improve targeting criteria, technology selection, and external validity.

International audience; There is a significant gap between the rhetoric of claims about adoption of farm-level natural resource management practices and the reality. New empirical evidence of low adoption from several developing countries suggests that on-farm natural resource management practices face significant constraints to adoption, and that they deliver heterogeneous private and public benefits. Five recommendations are given to the research community related to: targeting; scaling-up; the proper role of research; trajectories of diffusion; and measurement of environmental impacts.
