Farmer-managed innovation funds are being piloted in several countries to give smallholder farmers more control over agricultural research and development funding. These funds allow farmers to submit proposals for experiments and learning activities that address local priorities. Farmers then manage the selection process and oversee the funded activities. Evaluations show these funds have strengthened farmer organizations, increased farmer engagement in innovation, and stimulated interest from development organizations in supporting farmer-led research. However, fully implementing and scaling up such funds requires ongoing testing and efforts to engage more advisory services and scientists.
