Abstract

This paper describes the research design and household and plot characteristics, based on recent baseline data, for evaluating the impact of the use of the new genetically modified (GM) pod-borer resistant (PBR) cowpea variety in Nigeria. The evaluation aims to examine household-level effects of the use of PBR cowpea on key outcomes related to cowpea production and productivity. The study uses a cluster randomized controlled trial (c-RCT), employing an encouragement design with two treatment arms: PBR cowpea adoption (T1), PBR cowpea adoption plus complementary inputs (T2), and a control arm of conventional cowpea adoption (C). The data will be drawn from baseline, midline, and end-line surveys of the households in the three groups and we will use mean differences and regression analysis to determine causal impacts of interventions. In addition to the c-RCT, the evaluation will use qualitative methods to collect and analyze information through key informant interviews and focus group discussions. A related value chain component will also identify and describe value chain aspects of PBR cowpea use in Nigeria, including the identification of potential issues that may affect PBR cowpea adoption in Nigeria, such as factors which may enhance or hinder the functioning of the PBR cowpea value chain. The evaluation will contribute to a better understanding of how development practitioners and policymakers can account for farmer characteristics and practices to ensure positive outcomes from the release of GM crops in Nigeria and other countries in Africa.
