Resource Allocation and Productivity in National and International Agricultural Research was first published in 1977.Agricultural research in developing countries has grown rapidly in recent years. As the research system has expanded, questions about the productivity of research and the allocation of research resources have become important issues for development planners, science managers, donor agencies, and other individuals and institutions concerned with research operations and opportunities.In this volume, forty contributors - natural and social scientists and research administrators - provide a comprehensive analysis of the implications of agricultural science and technology for agricultural development. They examine recent evidence on the returns to investment in national and international agricultural research systems and explore the relevance of social and economic factors for the organization and management of these systems. In a final section they discuss research strategy and management issues that will affect the future productivity and organization of both the international and the national research systems.The material is based on papers given at a conference held at Airlie House, Virginia, sponsored by the Agricultural Development Council. Funding was provided through the U.S. Agency for International Development (USAID), support of the Council’s Research Training and Network Program, and by additional assistance from the World Bank.
