This document summarizes ILRI's work in West Africa. It notes that West Africa has a large livestock population that supports the livelihoods of many smallholder farmers. ILRI's main office for the region is located in Ouagadougou, Burkina Faso, with additional staff in other countries. Opportunities for ILRI include scaling research programs and partnerships with development organizations. Challenges include limited staff and changing perceptions of ILRI's role. Current research focuses on sustainable intensification of mixed crop-livestock systems, value chains, livestock and water interactions, and pastoral systems.
