Effective planning of programs and resources has become an even more important issue as funding for agricultural research becomes more scarce. In recent years, progress has been made in understanding the institutional processes involved in planning as well as sharpening the planning tools developed to improve such processes. This unique book summarizes the main approaches and experiences in agricultural research planning, focussing on recent developments in the planning field, the new issues and concerns in agricultural development and research and future challenges. In addition it helps clarify and contribute to the standardization of the terminology used in research planning.
