AbstractRecent attempts to predict the effects of climate change on soils, and hence land use, are often made at coarse scales and have made little use of the detailed soil, land use and climatic information available within the Community. Much of this information is available in digital form and lends itself readily to manipulation by computer procedures, often within geographic information systems. The current project is designed to take advantage of this situation. The target is a spatially distributed soil, agroclimatic and soil hydrological model to predict the effects of climate change on land use within the European Cornrnunity. The model structure draws on earlier work, which related simple soil properties, such as might be obtained during soil surveys, to crop suitability. More powerful approaches to the estimation of the soil hydrological state and crop water demands are being developed, as are new approaches to land type classification. The new model (ACCESS) is purposely designed to run at two levels; a more general approach will utilise the results of the site specific approach to allow extrapolation of the modelling to large areas of land, whilst the detailed model will use site specific data for calibration and validation. Development work is expected to finish mid-1994, after which further details will be available from the authors.
