Environmental water scarcity water sacarcity map

Over 1.4 billion people live in river basins where high water-stress levels threaten the environment, illustrating that we are withdrawing too much water from our rivers, streams and lakes. The 'global environment water scarcity map' is the first effort to look at the requirements of freshwater ecosystems on a global scale. It shows where and to what extent water diversions impact on freshwater ecosystems downstream, and enables researchers to look at the trade-offs between agriculture and the environment. The map is a product of a joint study by the International Water Management Institute (IWWI), the World Resources Institute (WRI), the Center for Environmental Systems Research of Kassel University (KU) and IUCN - The World Conservation Union.
