GM Cowpea Boosts Yields and Profits for Smallholder Farmers in Nigeria

A study conducted by researchers from the International Food Policy Research Institute finds that genetically modified (GM) pod borer-resistant (PBR) cowpea significantly improves farm yields and profits for smallholder farmers in Nigeria. The researchers compared PBR cowpea with conventionally improved varieties using a large cluster randomized controlled trial in two major cowpea-growing states.

The study showed that farmers who planted PBR cowpea harvested 21% more yield and earned 49% higher net margins compared to conventional varieties. The researchers found that the biggest gains were observed among those provided with the input package. The results varied widely among farmers, depending on factors such as plot size, pesticide use, household size, and farming practices.

The results of the study support the potential of GM cowpea to improve livelihoods and reduce losses from insect pests. However, the differences in results highlight how local conditions and resource constraints shape the benefits that farmers could receive from the new technology. The researchers conclude that there is a need for targeted distribution and support strategies to ensure the technology reaches small-scale, resource-constrained farmers.
