(Nexus Learning) The United States only uses 5% of its water for industry. By 2050, feeding a planet of 9 billion people will require an estimated 50 percent increase in agricultural production and a 15 percent increase in water withdrawals. The main water consuming sectors are irrigation, urban, and the manufacturing industry The quantities that make up those %’s are: Livestock – 40 million km², or 24.8 million mi.² MEXICO CITY — Farms and their wasteful irrigation systems are major contributors to water scarcity on the globe, nations at a world water summit said Saturday.

Most of this water (over 90 percent) is not used because we take long showers - we use it as “virtual water” through the products we buy. The remaining 39 percent or 43 000 km3 per year is converted to surface runoff (feeding rivers and lakes) and groundwater (feeding aquifers). Throughout the world, irrigation (water for agriculture, or growing crops) is probably the most important use of water (except for drinking and washing a smelly dog, perhaps).

Farm water may include water used in the irrigation of crops or the watering of livestock. Food and agriculture are the largest consumers of water, requiring one hundred times more than we use for personal needs. The global water crisis is one of governance (WWAP, 2006), much more than of resource availability. Water covers 70% of our planet, and it is easy to think that it will always be plentiful. As we get older, our bodies tell us to eat less meat anyway. UN-Water, through its web site unwater.org (2011c), summarized how water is used worldwide: 70% of the world’s freshwater is used in agriculture, 22% by industry, and; 8% for domestic use.
