Project Brief-World Water Vision

Issues to be dealt with at the various levels include: Water quality degradation (chemical, sediment, organic pollution) (pollution sources (agriculture, industry, urban areas, acid rain, defining ecosystem requirements) Water quantity degradation (flooding, droughts, temporal and spatial distribution, environmental shortage, defining ecosystem requirements) Land use and cover change (function of landscape positions under specific cover for water resource base, land drainage, land degradation, land conversion, riparian zones, headwaters, wetlands and floodplain conversion, extension of urban areas) Freshwater biodiversity loss (differentiation into species groups, key-stone species loss and effect on ecosystem functions, damming - loss of migration, loss of habitat diversity) Loss of ecosystem productivity (fisheries, floodplain productivity)
