Bridging the gap: How human-centered design can help unlock bottlenecks in the diffusion of small-scale irrigation in Nigeria

Ample evidence shows that small-scale irrigation (SSI) has positive impacts on agricultural productivity, poverty reduction, climate resilience and household food security, nutrition. Despite this, adoption of SSI has remained low in sub-Saharan Africa, including Nigeria, where previous research suggests potential for adoption is largest. Factors such as high cost of technologies, farmers’ risk behavior, lack of incentives, and lack of access to finance and capacity gaps have often been noted as key constraints limiting the adoption/scaling of SSI among smallholders. However, in an environment with low overall levels of use, it is important to not only focus on the challenges experienced by smallholder farmers, but also on those of key intermediary actors—specifically government, irrigation equipment distributors, and finance institutions—that are critical for a supportive enabling environment of SSI technology diffusion. To understand the constraints these groups encounter and propose innovative policy, financial, and supply chain solutions, we conducted a series of human-centered design (HCD) workshops in three locations in Nigeria. Key solutions proposed during nine workshops include the need for cross-sector coordination and policy harmonization, improved data and digital systems and platforms, customized financial products and risk-sharing options for SSI, capacity-sharing for extension services, and specific strategies to support women farmers so that they benefit equally.

Seed certification, certified seeds use and yield outcomes in Nigeria: Insights from nationally-representative farm panel data and seed company location data

CONTEXT Despite the importance of enhanced seed quality to agricultural productivity growth, evidence remains scarce regarding the nature and possible drivers of returns to formal sector quality assurance systems, including certified seeds production in countries like Nigeria that focus significantly on the formal-sector seed systems. OBJECTIVE This study narrows this knowledge gap by estimating the effect of the quantity of certified seeds produced and the spatial variations where they are produced on the use of certified seeds and yields. We also assess the yield effects of certified seeds use and their relationship with agroclimatic and socioeconomic conditions. METHODS We combine nationally-representative farm-household survey panel data with spatial data on the headquarters locations of seed companies, the quantity of certified seeds for maize, cowpea, and rice that they produce, and spatially explicit agroecological data. We apply panel fixed effects methods as well as instrumental-variable methods to address potential endogeneity associated with certified seeds use while also controlling for the use of improved varieties to separate their effects from the effects of certified seeds. RESULTS AND CONCLUSIONS Our findings indicate that the availability of certified seeds—captured by indicators of certified seeds produced by seed companies headquartered in the states of survey respondents—is associated with positive but declining marginal effects on certified seeds use and yields. These results are robust when we also consider the potential within-state heterogeneity in the proximity to seed company headquarters, as well as potential spillovers from the nearest adjacent states. The yield effects of certified seeds are heterogeneous and depend on agroclimatic conditions and farmers’ socioeconomic characteristics. The use of certified seeds is somewhat higher in areas with higher yield effects after controlling for certified seeds production. These patterns partly lead to observed non-linearities in certified seeds use because certified seeds may be more likely to be used by farmers with higher expected returns than farmers with lower expected returns. These results underscore the importance of spatially targeted efforts in enhancing certified seeds production capacity, together with the exploration of intermediate quality standards in the short term where costs of seed certification are high relative to returns. SIGNIFICANCE The study provides unique quantitative evidence in a nationally representative framework in an African country that returns to seed certification systems in the current setting significantly vary depending on contexts, including agroclimatic conditions.

Does labelling differentiate products and create price premiums? The case of tomatoes from northeast Nigeria

Does labelling differentiate products and create price premiums? The case of tomatoes from northeast Nigeria

This note describes a labelling experiment introduced to crates of tomatoes cool transported from the northeast region of Nigeria to Lagos or Port Harcourt. A label was attached to a random sample of crates to ensure that the quality of tomatoes is orthogonal to the labels and the destination market was not informed of the experiment. The label contained the information on (a) the project (IFPRI), (b) the transportation method (cool transportation), and (c) the origin of tomatoes (Jos or Gombe), as shown below. The experiment was conducted in the first rounds from Jos and Gombe (Lagos), and the fifth round from Jos (Port Harcourt). As expected, the labeled crates were priced higher than the unlabeled crates. About 9 to 33% of the sale price is attributed to improved information on the quality of tomatoes via the labels.

Improving Food Systems for Healthy Diets and Nutrition in Nigeria: Policies and Actions

Despite significant progress in addressing hunger and undernutrition in the early 2000s, malnutrition, in all its forms, remains a major challenge in all regions of the world.  Unhealthy diets remain the primary drivers of many forms of malnutrition, including undernutrition, overweight and obesity, micronutrient deficiencies, and diet-related noncommunicable diseases.  Today, the number of people who […]
