Abstract
An assessment system that combines digital information on soil types, climates, slopes and crops with simulated values of nitrate leaching a nd erosion within a geographical information system was developed. The system was used for assessing risks of nitrate leaching and erosion o n the regional as well as national scale, having municipalities as the level of aggregation. In Denmark the system has been used for assessi ng risks of erosion at a catchment scale.
