This document summarizes findings from ASTI, an initiative that collects data on agricultural research and development (R&D) spending in developing countries. It finds that after a period of decline, global public spending on agricultural R&D increased 22% from 2000-2008, driven largely by growth in middle-income countries like China, India, and Brazil. Private sector R&D spending, concentrated in OECD countries, also increased significantly. However, agricultural R&D spending remains low and volatile in the world's poorest countries. The document concludes that while global agricultural R&D investments are no longer declining overall, more attention needs to be paid to increasing investment in the poorest nations.
