Impact assessments of gender transformative interventions in Tanzania: Pre-analysis plan

Transforming gender norms improves women’s wellbeing and may help close the agricultural productivity gap, yet evidence on pairing them with agriculture interventions is limited. We will test an innovative approach to developing and delivering gender transformative interventions with cassava producers in Tanzania. Using a cluster-randomized controlled trial, we examine the impact of these gender transformative interventions paired with standard agricultural service, compared to agricultural services alone, on the primary (gender norms, decision making, and women’s leadership) and secondary (agricultural productivity, women’s savings, and women’s access to land) outcomes. Qualitative methods will examine changes in intra-couple dynamics (communication, decision making, and division of labor).

Insecticide use, farmers’ self-reported health status, and genetically modified cowpea in Nigeria: Findings from a clustered randomized controlled trial with causal

Insecticide use, farmers’ self-reported health status, and genetically modified cowpea in Nigeria: Findings from a clustered randomized controlled trial with causal

Excessive insecticide use in smallholder agriculture can threaten human health and the environment. We evaluate the effects of receiving a genetically modified cowpea variety that confers resistance to the legume pod borer (Maruca vitrata) using a clustered randomized controlled trial with an encouragement design in Nigeria. We find that farmers who received the pod borer-resistant (PBR) cowpea with complementary inputs significantly reduce insecticide volumes and report fewer days of insecticide-related illness compared to farmers who only received a conventional cowpea variety. Farmers receiving PBR cowpea alone experience smaller, mostly insignificant reductions. To explore heterogeneous responses, we combine ANCOVA (analysis of covariance) interactions with machine learning-based Causal Forest estimates of Conditional Average Treatment Effects (CATEs). Results reveal that smaller, less wealthy, and labor-constrained households experience the largest reductions in insecticide use and health improvements, whereas wealthier farmers or those with higher baseline spraying practices experience lower reductions. Women-managed plots exhibit modestly higher responsiveness. Our findings highlight the importance of moving beyond average effects and seed distribution toward targeted, context-specific interventions that account for behavioral and resource constraints in smallholder farming systems.

Food systems in conflict-prone and climate-affected areas of Northern Nigeria: Humanitarian and development challenges

Food systems in conflict-prone and climate-affected areas of Northern Nigeria: Humanitarian and development challenges

Protracted conflict and climate shocks have profoundly disrupted food systems in northern Nigeria, yet little empirical evidence exists on how these shocks shape the functioning of the region’s food system (production, transportation, value addition, and trade). This study addresses this evidence gap by combining GIS-based mapping, cost structure analysis, and investment opportunities in food production, transportation, processing, and trade in key staple commodities across conflict-prone and climate-affected areas of northern Nigeria and connected market hubs. The analysis quantifies cost structures for key food supply chain actors, identifies systemic food system inefficiencies driven by conflict and climate factors, and examines how these factors undermine both commercial and humanitarian food flows. By integrating commodity-specific diagnostics with stakeholder perspectives, the study offers an evidence-based rationale for prioritizing interventions in conflict contexts. Two investment cases—on-farm storage and localized wheat milling—illustrate how targeted actions can reduce losses, enhance resilience, and create co-benefits for humanitarian operations and market recovery. By combining food-flow maps and cost structures for multiple actors along the food supply chain in a high-risk environment, and by demonstrating simplified approaches to linking empirical diagnostics with practical investment strategies, the study’s findings contribute to the literature on the functioning of food systems in conflict-prone and climate-affected contexts. In addition, the findings provide evidence to support policy changes, interventions, and investment decisions aimed at transforming food systems and addressing structural failures, while enhancing the efficacy of short-term humanitarian interventions. They also address the underlying causes of chronic food insecurity and support economic recovery in the region.
