Australia’s water shortage: The big dry

Australia is struggling to cope with the consequences of a devastating drought. As the world warms up, other countries should pay heed

THE mouth of the Murray-Darling river sets an idyllic scene. Anglers in wide-brimmed sunhats wade waist-deep into the azure water. Pleasure boats cruise languidly around the sandbanks that dot the narrow channel leading to the Southern Ocean. Pensioners stroll along the beach. But over the cries of the seagulls and the rush of the waves, there is another sound: the mechanical drone from a dredging vessel. It never stops and must run around the clock to prevent the river mouth from silting up. Although the Murray-Darling is Australia’s longest river system, draining a basin the size of France and Spain combined, it no longer carries enough water to carve its own path to the sea.

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.
