How do policy environments influence technology adoption? Insights from Nigeria’s pod borer resistant (PBR) cowpea experience

Policymakers are increasingly considering the promise of modern biotechnology, including genetically modified organisms (GMOs) to help solve development problems in health, agriculture, and other fields (Zambrano et al., 2022). However, debates persist around health and environmental implications (National Academies of Sciences, 2016; Raman, 2017; Smyth et al., 2021). The regulation of GMOs varies globally, with some countries implementing outright bans or imposing stringent controls (Sarkar et al., 2021; Yali, 2022). A recent study examines the Nigerian policy environment for Pod Borer Resistant (PBR) cowpea, which has been genetically engineered to resist the legume pod borer (Maruca vitrata) [Mockshell et al., (unpublished)]. Legume pod borers significantly reduce cowpea yield and quality, with losses of up to 80% reported (Andam et al., 2024; Mockshell et al., 2024). This policy note summarizes the findings of the paper, providing insights to guide policy development around the adoption of biotech food crops in Nigeria and other countries in Africa South of the Sahara (SSA). The primary research question is: Is there an enabling policy environment for PBR cowpea and what factors contribute to it?

Assessing the development impacts of bio-innovations: The case of genetically modified maize and cassava in Tanzania

Assessing the development impacts of bio-innovations: The case of genetically modified maize and cassava in Tanzania

Tanzania’s agriculture is characterized by low productivity due to unpredictable rainfall and the prevalence of pests and diseases. Genetically modified (GM) maize offering protection against drought and insects are being developed. Likewise, GM varieties resistant to cassava brown streak disease were developed. Building on prior crop-based analyses, we use the Rural Investment and Policy Analysis (RIAPA) CGE model to assess the impacts of the adoption of those GM crops. GM maize and cassava have positive effects on the economy, the Agri-Food System (AFS), and poverty. Given its stronger linkages in the AFS, the effects of the GM maize are stronger, especially in higher adoption and high yield scenarios. Likewise, the effects on the poorest and rural households are greater. The high variation across scenarios, and the significant effect of the high adoption/high yield scenarios, suggests a high return to investments and policies that realize these adoption rates and yield potential.

Impact evaluation of the use of PBR cowpea in Nigeria: Baseline report

Nigeria is the largest consumer and producer of cowpea in Africa. Produced predominantly by smallholder farmers, cowpea is relied on by millions of Nigerians and is one of their main sources of affordable protein. Despite cowpea’s economic relevance (Nwagboso et al. 2024; Phillip et al. 2019), cowpea yields in Nigeria have barely grown over the last 20 years. One of the main abiotic constraints of the crop is the pod-borer insect (Maruca vitrata), which can cause damages of up to 80 percent. Given that conventional breeding has not been successful in addressing this constraint, local and international efforts over the last decades focused on developing a pod-borer-resistant (PBR) cowpea. The culmination of these efforts in Nigeria was the commercial release of the PBR cowpea variety SAMPEA-20T in late 2019. This is a significant milestone, as it was the first transgenic food crop to be approved for cultivation in Nigeria. In its programming under the “Feed the Future Innovative Maize and Cowpea Technologies to Increase Food and Nutrition Security in Africa” activity, implemented by the African Agricultural Technology Foundation (AATF), the United States Agency for International Development (USAID) aims for an adoption rate of PBR cowpea in Nigeria of 25 percent by 2025, with yield gains of 20 percent and accompanying reductions in pesticide applications. The International Food Policy Research Institute’s (IFPRI) Program for Biosafety Systems (PBS) is leading a five-year (2021–2026) impact evaluation (IE) project, funded by USAID. The study goal is to generate causal evidence of the use of the PBR cowpea variety and its consequential household and farm impacts and associated value chain effects. In a collaboration with IFPRI’s Nigeria Country Office, PBS is leading and coordinating the overall study while the IFPRI-Nigeria Country Office designs and implements the quantitative and qualitative approaches to the evaluation. IFPRI has worked with technology developers, the AATF and its partners (including private local seed companies), to ensure access to necessary data and cooperation by the evaluation team, while maintaining the team’s independence. To ensure such required independence, the evaluation team has separated the cooperation in implementing the evaluation (including distributing inputs) from the data analysis. The evaluation team will continue to maintain its independence in the methodological approach and the analysis of the results from the implemented randomized controlled trial (RCT), adhering to international standards.
