This study focuses on the most vulnerable types of land use: nature related to land and water and drinking water supplies from groundwater and large surface waters. The sensitivity of these types of land use are compared to the environmental stresses. In areas where nature and drinking water are threatened or possibilities are not fully exploited, region specific strategies for environmental policy are formulated to balance environmental stresses and vulnerable land use. A large part of this study concentrates on developing methods to analyze the environmental stresses in relation to future and current land use. In areas with vulnerable land use the transport and destination of polluting components by atmosphere and surface waters are analysed. The groundwater flow pattern between seepage areas and infiltration areas is analyzed and related to the leaching of pollution in the infiltration areas. With this overview of environmental stresses strategies for protection of vulnerable land use in specific areas are formulated. In case of surface water pollution in regional water systems internal emissions determine most of the pollution. In the large watersheds feeding the main rivers most of the pollution comes from abroad. For atmospheric transport of polluting compounds destination is evenly devided between internal, inland and foreign sources of pollution. Based on environmental pressures and flow of pollution region specific strategies are formulated to protect vulnerable land use.
