India-China Water Stress - Potential Conflict
This Times of India article describes the potential for conflict between India and China over water.
Prime Minister Manmohan Singh recently visited China and discussed with his counter-part water that flows out of the Tibetan Himalayas to feed India. China's control over the Tibetan plateau means that it controls the source of most of the river systems that sustain south and southeast Asia. The Indus, Gang-Bramapurta, Yangtze, and Mekong rivers all originate in the Himalayas - and 1.3 billion people live in the drainage basin of the Himalayan rivers.
China and India, the two most populous countries in the world are already water-stressed and China has embarked on massive water diversion projects.
"China is toying with massive inter-basin and inter-river water transfer projects. Its Great South-North Water Transfer Project is an overly ambitious engineering attempt to take water through man-made canals to its semi-arid north. The diversion of waters from the Tibetan plateau in this project's third leg is an idea enthusiastically backed by President Hu Jintao, a hydrologist by training."

Israel offers to pass along desalinated water to Jordan
In an example of how water scarcity can compel cooperation between rival states competing over scarce resources, the Jerusalem Post is reporting that Israel has offered to supply desalinated water from the Mediterranean Sea to Jordan (the world's 10th water-poorest country).
International Crisis Group recently released a report on Climate Change and Conflict which read in part:
"Importantly, climate and environmental stress may also play a role in producing collaboration instead of violence. Water is an important example. Historically, water scarcity has often – though certainly not always – worked to favour cooperation between states. Interstate dialogue prompted by diminished water supplies, particularly, can build trust, institutionalise cooperation on a broader range of issues and create common regional identities."

South Africa braces for water crisis
Each American consumes 6 800 litres a day, compared to 2 500 litres in South Africa.
Heavy past investment in water infrastructure, such as dams, had saved South Africa from having to tackle water scarcity. Climate change, however, will prevent dams from filling up.
Other factoids:
l Meat, milk, leather and other livestock products account for 23% of global water use in agriculture. The industry uses up to 1 150 litres of water per person per day.
l Wearing a cotton T-shirt today? It took 2 900 litres to produce it — and that’s before you’ve put it in the washing machine. About 3,7% of the world’s water used for crop cultivation goes on cotton.
l The average person uses 70g of sugar per day, equivalent to 100 litres of water. Cane sugar consumes 3,4% of the water used for crops worldwide.
l It takes 75 litres of water to produce a 250ml glass of beer — most of it used in growing the barley.

Guardian UK: Is water the new oil?
A great summary of water scarcity issues including conflict, pricing, trade, to name a few.
Is water the new oil?It's the world's most precious commodity, yet many of us take it for granted. But that's all about to change

By Juliette Jowit
Global population, economic development and a growing appetite for meat, dairy and fish protein have raised human water demand sixfold in 50 years. Meanwhile, supplies have been diminished in several ways: an estimated 845,000 dams block most of the world's rivers, depriving downstream communities of water and sediment, and increasing evaporation; up to half of water is lost in leakage; another 1bn people simply have no proper infrastructure; and the water left is often polluted by chemicals and heavy metals from farms and industry, blamed by the UN for poisoning more than 100m people. And still the rains are getting less reliable in many areas.
Underlying these problems is a paradox. Because water, and the movement of water, is essential for life, and central to many religions, it is traditionally regarded as a 'common' good. But no individuals are responsible for it. From Wadi Esseir to the arid American Midwest, farmers either do not pay for water or pay a fraction of what homeowners pay, so they have less incentive to conserve it and might deprive suppliers of funds to improve infrastructure.
