In support of this data she cites words of Don Wilhite, director of NDMC, who says that our society "is moving rapidly into urban areas, and, as a result, we're experiencing more and more water shortage problems ". As already mentioned, another problem, which has considerable influence on this situation, is climate change. It is generally known, that climate is closely related with local rainfall and water availability. Peter Rogers (2008) claims that surveys, which investigate the effects of climate change on water availability by 2025 display that it will bring scarcity to loads of places. It is expected that climate change will exacerbate aridity and reduce supply in many regions, which lead to droughts. It came to the "Mighty Murray", one of the Australia's major river, is on the verge of collapse: in some places, children can jump over it. (N. MacDonald,) one more reason for existing situation is irrational waste of water. If we want to find an adequate solution to this problem, we must try to define how much freshwater each person requires and what factors impede supply and increase demand. Malin Falkenmark estimates that each person in the world needs approximately 1,000 cubic meters of freshwater per year. This number includes water for drinking, growing food, hygiene and sanitation (P. Rogers, 2008). One of the possible solutions to diminish consumption of water is rational water management. Nowadays cities are using a diversity of techniques to reduce water shortage, for instance, restricting outdoor water usage. It can be reached by application of different combination of methods, such as limiting water usage to certain times (e.g. half a day, only night time, only on weekends) or countenancing drip irrigation and the use of mouth-pieces on hoses. Besides, there are a lot of practices to advocate more efficient use of indoor water: the installation of low-flow toilets and water-saving shower heads.
