Under the auspices of the International Benchmark Sites Network for Agrotechnology Transfer (IBSNAT) Project a Decision Support System for Agrotechnology Transfer (DSSAT) has been developed. DSSAT operates on a personal compute rand includes data base management programs for climate, soil, and cultural practice information; crop simulation models for cereal grains, grain legumes, and root crops; and seasonal strategy and risk analysis programs. The IBSNAT crop models use daily weather data, i.e., maximum and minimum air temperature, solar radiation, and precipitation, as inputs. One of the applications of DSSAT is, therefore, to study the potential impact of climate change on agricultural production. A new and special version of DSSAT (Version 2.5) was developed to facilitate studies of the effect of climate change on crop performance. In this version, the daily canopy photosynthesis and transpiration sections of the CERES and GRO models were modified to respond to changes in CO{sub 2} concentration. The management sections of the models and the strategy analysis program were expanded to include the option to modify weather data interactively. This decision support system has been used to study changes in crop yield, irrigation requirements, and other responses to global climate change in various regional, national, and international research programs. 65 refs., 7 figs., 6 tabs.
