Due to expanding irrigation areas, accelerated industriali¬sation and a growing population, water demand is increasing dramatically, leading to an over¬exploitation of groundwater. In addition, the global climate change will have a large impact on the sensitive water balance in the region. A significant re¬duc¬tion of the vital glaciers is anticipated. The forecasted effects will pose a major challenge to the key actors, especially concerning the supply of drinking water. Sustainable con¬cepts that promote the efficient use of water in agriculture, industry and private households are to be etablished. Also, sustainable recycling concepts for wastewater treatment are to be im¬ple¬men¬ted in order to counter the shortage of clean water.
