Mapping water provisioning services to support the ecosystem-water-food-energy nexus in the Danube river basin

摘要: Water, food and energy are at the core of human needs there is a boundless complex cycle among these three basic needs. Ecosystems in center this nexus, since they contribute to provision each component, making it imperative understand role ecosystems securing food, water for well-being. In study we aimed map assess provisioning services associated benefits support ecosystem–water–food–energy nexus by taking into account environmental flow requirements riverine using hydrological model Soil Water Assessment Tool (SWAT). We developed framework that includes indicators renewable (capacity ecosystem provide water) use (service flow) applied Danube river basin over period 1995–2004. scarcity were used possible subbasins, analyze spatial match availability use. The results show modelling instrumental perform integrated analysis nexus; mapping powerful tool display regulatory delivered ecosystems, can analysis.
