Navigating Nigeria’s food system challenges in the face of inflation and reform

Main Messages: 1. Low-income households in both urban and rural areas are hardest hit by rising food prices. Post-reform (fuel subsidies removal and exchange rate liberalization) price shocks and persistent inflation have disproportionately affected poor urban and rural households, forcing them to reduce food consumption and dietary diversity. Malnutrition and food insecurity are on the rise, particularly among children and women-headed households, with sharpest impacts in conflict-affected areas. 2. Small-scale farmers are not benefiting proportionately from price increases. Despite surging food prices, small-scale farmers face escalating input costs, poor market access, and structural in-efficiencies that leave them with marginal gains far below the rate of inflation. 3. Trading networks maintain healthy margins, amplifying systemic inefficiencies. Traders and intermediaries dominate the food supply chain, passing on increased costs to consumers while pre-serving or even increasing their profit margins, highlighting inequities in the distribution of benefits along the value chain. 4. Recent economic reforms and external shocks exacerbate structural weaknesses. Economic reforms, including the removal of fuel subsidies and exchange rate adjustments, have amplified existing challenges in the food system, including high transport costs, inadequate infrastructure, and fragmented markets. 5. Policy interventions should protect vulnerable groups and strengthen local food systems. Addressing these disparities requires targeted safety nets for consumers, support for small-scale farmers, and systemic investments to reduce inefficiencies in the value chain while promoting cli-mate-resilient food systems.

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.

Conflicts, crop choice, and agricultural investments: Empirical evidence from Nigeria

Conflict remains a major driver of poverty in Africa. Conflicts and political instability in the region have been increasing recently and are drawing more attention in public discourse. While it is widely acknowledged that conflicts disrupt agricultural production and food systems, the full extent of the damage inflicted on the lives and livelihoods of farming households and the mechanisms to redress this harm remain poorly understood. In particular, the link between violent conflicts and households’ land allocation and related agricultural investment decisions remains understudied. In this study, we use geocoded longitudinal data along with detailed agricultural panel household surveys in Nigeria to assess the impact of violent conflicts on crop choice decisions and related agricultural investments. Specifically, we explore how farmers’ land allocation and agricultural investment decisions relate or respond to the outbreak and intensity of violent conflicts. We find that violent conflicts are associated with a reduction in the share of both land area cultivated and area harvested. We also find suggestive evidence that violent conflicts may shape farmers’ crop choices and related investments, as violent conflicts are associated with reduction in the share of land allocated to long-term crops (e.g., perennial crops, trees, roots and tubers). Overall, our findings suggest that violent conflicts can negatively influence farmers’ agricultural investments directly by affecting both land utilization patterns and portfolio allocation across activities with varying returns to investments.
