This book includes papers tied to a collaborative project to undertake policy analysis and projection studies on supply, demand, and trade of rice in some of the major rice-producing countries. The papers were presented at a workshop on Medium- and Long-Term Prospects of Rice Supply and Demand in the 21st Century held at IRRI headquarters on 3-4 December 2001. Medium- and long-term projections of rice supply, demand, and prices are key information needed to guide national policy decisions and investment plans. In close collaboration with researchers and scientists from the NARES, IRRI, and IFPRI embarked on the collaborative research project to make an in-depth analysis of the changing structure and dynamics of rice supply and demand and to institutionalize the research and policy analysis capacity and projection work as a core research activity in selected NARES. With financial support from the Japanese government and from core funds of IRRI and IFPRI, the project started with the following countries selected to participate: Thailand, Vietnam, Indonesia, Philippines, Malaysia, Myanmar, Japan, South Korea, Taiwan (China), Bangladesh, India, Nepal, and Pakistan.
