The CASA programme will make the commercial and development case for investing in agribusinesses that source produce from smallholders. It will do this by demonstrating how this can be done effectively, by bridging evidence gaps and by ensuring investors and policymakers have access to the right information and people to make inclusive agribusiness models succeed. Smallholder related agriculture in Africa and South Asia suffers from a low penetration of effective farm inputs and weak links between farmers and commercial buyers. These drive down smallholder farm productivity and quality, increasing the perceived risk faced by agribusiness that source produce from smallholders and reducing investor appetite for investing in these businesses. By showcasing successful models for businesses that source produce from smallholders and pulling together the evidence base supporting the commercial and development impact of their business models, CASA will attract more investment into the sector, boosting economic growth and raising demand for smallholder produce.
