CGIAR is a global partnership focused on research for food security. It works on improving small-scale livestock and fish production systems to better meet the needs of poor people. Key approaches include taking a whole value chain perspective, focusing on select chains with potential for pro-poor transformation, and working with partners on integrated interventions. Research addresses constraints in smallholder dairy, sheep/goat, pig, and aquaculture systems. The goal is to increase productivity in a sustainable and equitable manner to improve poor people's access to affordable animal-source foods.
