Smallholder farmers in Zimbabwe face challenges like climate changes and limited access to resources. To help improve their food security, organizations introduced improved sweet potato plants using biotechnology. Farmers who adopted these plants had more resources and were influenced by factors like farmer training and participation in trials. The new sweet potato variety had benefits like drought resistance and better storage, leading to increased household welfare. To ensure the success of such interventions, collaboration between funders, government, researchers, extension services, and farmers is crucial.
