As for the market, when it approaches water it meets all sorts of obstacles: water is difficult to move, difficult to measure, difficult to price and often difficult to charge for, since many people think it should be free.

Trading in water rights may one day bring order to the 20m well-users in India, but not in time to feed the 1.4 billion Indian mouths expected by 2025.
