Taking the example of the e-voucher system for input subsidies in Zambia, this video presents the Feed the Future Innovation Lab for Food Security Policy (FSP). This lab, funded by USAID, works towards a sustainable and inclusive agrifood system through evidence building, improving policy processes, and influencing policy change at country, regional and global levels. FSP is led by Michigan State University Food Security Group, in partnership with IFPRI and the University of Pretoria.
