(Source: The Economist) Long but well-written article about the water shortage in Australia - which is having a profound effect on that country. (click on title above for full article)Australia is struggling to cope with the consequences of a devastating drought. As the world warms up, other countries should pay heed. John Howard, Australia's prime minister, arrived here in February and urged the four states through which the Murray-Darling flows to hand their authority over the river to the federal government. After seven years of drought, and many more years of over-exploitation and pollution, he argued that the only hope of restoring the river to health lies in a complete overhaul of how it is managed. As the states weigh the merits of Mr Howard's scheme, the river is degenerating further. Every month hydrologists announce that its flow has fallen to a new record low (see chart). In April Mr Howard warned that farmers would not be allowed to irrigate their crops at all next year without unexpectedly heavy rain in the next few months. A region that accounts for 40% of Australia's agriculture, and 85% of its irrigation, is on the verge of ruin.
