Masterarbeit aus dem Jahr 2009 im Fachbereich Geowissenschaften / Geographie - Bevolkerungsgeographie, Stadt- u. Raumplanung, Note: 1,0, Universitat Salzburg (Geographie und Geologie), Sprache: Deutsch, Abstract: Water is supposed to be the source of any kind of life. It has an essential meaning for human beings and it is an ending good. Therefore it became a subject of challenges for the future within the last decades. Integrated Water Resource Management has become a key factor regarding a sustainable treatment of the resource water. Water management is not only a matter of providing potable water but it is a matter of integrating ecological, economical and social aspects. Clean potable water supports the efforts of containing Diarrhea (still cause of death to 1.5 Million people every year (cit. POPULATION REFERENCE BUREAU; 2008; p.8). If sewerage is treated before being used in agriculture, the occurrence of diseases related to toxic and bacteriological pollution can be reduced. Furthermore the consumption of potential drinking water decreases. This is just one example that shows how simple methods can improve the situation remarkably. Many regions across the world suffer from acute water shortage. This situation will tighten even more due to climate change, an increased population growth, and along with this a significantly higher demand of potable water. The precipitation is especially in arid regions too low to countervail the extraction of groundwater. In these cases specific methods have to be implemented (on the supply side as well as on the demand side) to provide an ensured water supply for future generations. Therefore an Integrated Water Resource Management according to the UN Millennium Development Goals is indispensable.
