The impact of genetically modified cowpea on yields, postharvest losses, and profitability in Nigeria: Findings from a cluster randomized controlled trial

We assess the impacts of a genetically modified pod borer-resistant (PBR) cowpea variety in Nigeria through a cluster randomized controlled trial conducted in two major cowpea-cultivating states. Our design allows us to examine the impacts of PBR cowpea with and without a package of complementary inputs (fertilizer and insecticides) and in comparison to farmers who received only a conventional improved cowpea variety. Results indicate that farmers who received and planted PBR cowpea experienced significant increases in yield (21 percent) and net margins (49 percent) compared to those growing the conventional variety, with larger gains observed among those provided with the inputs package. Analysis of heterogeneous effects indicates substantial variation in outcomes based on baseline characteristics such as household size, landholding, pest control practices, and wealth. Estimation of group average treatment effects and classification analysis using a causal machine learning approach identify plot size, pesticide use, and assets as key drivers of impact heterogeneity. Findings highlight the need for targeted dissemination strategies to realize the sizable benefits of PBR cowpea for small-scale, resource-constrained farmers.

Does small-scale irrigation affect women’s time allocation? Insights from Ethiopia

Small-scale irrigation (SSI) interventions have received increasing attention as a potential pathway for women’s empowerment in sub-Saharan Africa. One key aspect of women’s empowerment that SSI can influence is women’s time burden. Hypothesized benefits of SSI for women are less energy exertion and reduced labor in agriculture. Yet, these hypotheses have not been tested empirically. We explore how household adoption of different SSI technologies affects the time allocation of women in the household, using two rounds of intrahousehold panel survey data from Ethiopia. Two different approaches are used to address potential endogeneity issues related to time-constant and time-varying factors that may be correlated with both SSI and time use: an instrumental variables-correlated random effects approach and a fractional multinomial logit-correlated random effects with control function approach. The results suggest that household use of SSI in general is associated with an increase in women’s leisure time. The results further suggest that household use of motor pumps is associated with an increase in women’s leisure time and reductions in the time they spend on farming and personal care. Given that women often provide the labor for irrigation using manual, labor-intensive methods, such as watering cans, buckets, or hand- or foot-powered treadle pumps, the results suggest that SSI using motorized methods has the potential to free up women’s time in farming and enable more leisure time. These findings have broad implications for women’s empowerment and labor allocation. Future research using new and more comprehensive data could explore the mechanisms for the findings in this study and determine if SSI enables women to improve their ability to allocate their time to activities they prefer.
