Peak oil has generated headlines in recent years, but the real threat to our future is peak water. There are substitutes for oil, but not for water. We can produce food without oil, but not without water.

We drink on average four litres of water per day, in one form or another, but the food we eat each day requires 2,000 litres of water to produce, or 500 times as much. Getting enough water to drink is relatively easy, but finding enough to produce the ever-growing quantities of grain the world consumes is another matter. ...

“We live in an increasingly water insecure world where demand often outstrips supply and where water quality often fails to meet minimum standards. Under current trends, future demands for water will not be met,” Ban said. ... Read more about Ban Ki-moon: World on course to run out of water

OSLO, March 22 (Reuters) - Stresses on water supplies aggravated by climate change are likely to cause more conflicts and water should be considered as vital to national security as defence, a United Nations report said on Friday.

About 145 nations share river basins with their neighbours and need to promote cooperation over a resource likely to be disrupted by more frequent floods and heatwaves, it said. ... Read more about Water as vital to national security as defence - UN

Equitable, broad-based public access to sustainable, sanitary supplies of water is increasingly being seen as a security issue. A growing world population, global warming, growing fossil fuel use and greenhouse gas emissions and ongoing, growing disparities in the distribution of wealth and income and business-as-usual political economy – all threaten national, regional and international efforts to assure all members of society fair access to sustainable water resources. ...

Significant amounts of water are needed in almost all energy generation processes, from generating hydropower, to cooling and other purposes in thermal power plants, to extract­ing and processing fuels. Conversely, the water sector needs energy to extract, treat and transport water.

These interdependencies complicate possible solutions and make a compelling case to expeditiously improve integrated water and energy planning in order to avoid unwanted future scenarios. ... Read more about Thirsty Energy - Energy and Water's Interdependence
