Water use

Water use

Water use can mean the amount of water used for a given task or for the production of a given quantity of some product or crop. In light of the water shortages in various parts of the world, it is important to consider water use and water efficiency. See the article "Virtual water" for more information on this topic.

The term "water footprint" is often used in the sense of the amount of water used by a consumer.

World water use has been growing rapidly in the last hundred years (see [http://environment.newscientist.com/data/images/archive/2670/26700101.jpggraph] from New Scientist article [ [http://environment.newscientist.com/channel/earth/mg19926700.100-looming-water-crisis-simply-a-management-problem.html "Looming water crisis simply a management problem"] by Jonathan Chenoweth, New Scientist 28 Aug., 2008, pp. 28-32.] ). From 1900 to 2000, water use for agriculture went from about 500 to 2500 cubic kilometres per year, while total use rose from around 600 to more than 3000 cubic kilometres per year.
