摘要: Several issues impact the water sustainability of a river basin. Among them are social, economic, and environmental aspects. However, they often treated separately, not as an integrated, dynamic process. In order to integrate hydrologic, environmental, life policy issues, well existing pressures responses in one quantitative, dynamic, aggregated indicator, watershed index (WSI), which uses pressure–state–response function, was developed is proposed this paper. Applied 2,200 km2 Unesco–HELP demonstration basin Brazil (SF Verdadeiro), value obtained for WSI 0.65, represents intermediate level sustainability.
