A focused research and development program for a crop or cropping system should be based on a comprehensive analysis of the relevant database for the target region. This database should comprise production and area trends, and factors affecting production including biotic, abiotic, socioeconomic, and utilization constraints. The information should be presented as clearly as possible in order that it may be adequately interpreted by a wide range of persons, including nonspecialists. The recent development of geographical information systems (CIS) —computer-based packages which allow rapid plotting of large data sets as digitized maps — is a great help in this area. GIS packages were originally developed for land-use...........................The purpose of this paper is to briefly describe the use and potential of EIS in understanding crop adaptation and in research prioritization. We are beginning an EIS study of adaptation of groundnut in Vietnam, which we wi l l draw upon to illustrate the application of EIS to crop research and development.....
