It works in more than 20 countries in Africa, Asia and Latin America and has an annual budget of about US$22 million provided by more than 35 donor organizations. The Centre's ultimate purpose is to improve human welfare by reducing poverty, increasing cash income, improving food and nutritional security, and enhancing ecosystem resilience in the tropics, through improved agroforestry systems.
