Australia is hit by the worst drought ever. The damage caused to the economy is increasing, as are also the restrictions on the use of water
Summer in Australia is already over, but the worst drought ever shows no sign of stopping. Since 2002 in Australia it has rained less, it has rained too little, summer or winter makes little difference: what was seen at first as a cyclic climatic event is now seen as a consequence of the global warming caused by man. And the price is payed by everyone: the national economy, the farmers in the boundless outback, but also the inhabitants of the big cities, where the restrictions on water use get harsher. So much so that a new future has to be immagined, where water won’t be abundant any longer and it will be necessary to obtain it in other ways.
 
Damage to the economy. The drought has lasted six years now and the economy suffers too. In the last winter, fruit and vegetable exportation dropped by 60 percent, in particular because of the collapse of the wheat crop. In the first reports of 2007, the national office for agriculture foresees that the cotton crops will be reduced by half, since they require great quantities of water, and that the rice production will plummet by 90 percent. John Howard’s government calculated that the drought will reduce the gross domestic product by .75 for the 2006-2007 period. Canberra has nearly doubled (upped by 83 percent) the agricultural subsidies to help the farms hit by the lack of rain.
 
Restrictive measures. The lack of water does not only concern the traditionally more arid western regions. Even the big cities in the south-west, such as Sydney and Melbourne, have for years been applying restrictions on the use of water, which are more or less strict according to the period. At the moment, in Sydney it is forbidden to wash one’s car with a hose: you can only use a bucket. Watering the garden is allowed in two time intervals on Wednesdays and Saturdays. You have to have a special authorization to fill a swimming pool. The results are visible: in the last three years the city has reduced the consumption of water by 13 percent. But at a national level the situation remains worrying. Last autumn, an electricity company urged people to forgo “non-essential activities” under the shower, such as singing, to save water and electricity. Australians were also invited to eat less meat, because cattle breeding requires more water than agriculture.

Il prosciugamento di una diga che serve la città di SydneyNew projects. Besides tightening belts, various projects for the supplying of water are being assessed in the Country. Next July, Sydney will start building a desalinating plant, which will make sea water drinkable. Perth already has a similar structure, Adelaide and Melbourne are thinking about it; but these projects caused protests from environmentalists, since these plants require a great deal of energy to work. Even more controversial, however, is Brisbane’s project of making drain water drinkable. Local authorities had promised a referendum to decide the issue; but they then imposed their “yes”, maintaining that they could not run the risk of the project falling through. The state of Western Australia, among the most badly hit by the lack of rain, even thought up waterworks 3500 kilometer long, to transport water from a rain-rich region. But the project, considered too costly, fell through. However, if the tendency does not change, Australia might in future have to think up solutions even more radical than these.
