Over time, scientists, technologists, and resource managers in affiuent countries have devised and institutionalized methodologies for exploiting and managing natural resources in their own environments with considerable success. In doing so, they have provided models, at least of development and affiuence, that the less developed countries seek to employ. An international symposium involving both invited and contributed papers addressing the technological and institutional challenges of sustainable development of natural resources in the Third World was staged in September 1985 in Columbus, Ohio, co-sponsored by The Argonne National Laboratory of Argonne, Illinois, The Tropical Renewable Resources Program and the School of Natural Resources of The Ohio State University, and the United States Agency for International Development. This volume presents selected papers from the symposium.
