“Wars of the next century will be fought over water.” This latest warning comes from the World Bank, the largest international investor(投资者)in water projects.

So is the world running out of the stuff? No. The total quantity of fresh water on the earth surpasses(超过)all possible human needs. But tell that to the government of Jordan, which has drawn its underground water almost dry since Israel diverted(转移)much of its largest water source, the river Jordan.

There is no world crisis(危机), but there are crises of under investment, of political conflict over rivers that cross national boundaries , and of rather foolish water management.

The Middle East is the likeliest place for future water wars. A long-term settlement between Israel and its neighbors will depend at least as much on fair allocation(分配)of water as of land. Iraq and Syria watch and wait as Turkey builds dams in the headwaters of the Euphrates. Elsewhere, India angers Bangladesh by diverting to its fields the thin dry-season flow of the Ganges.

Meanwhile, the best places for dams are mostly used up. Engineering and environmental costs of developing new water sources will be much higher than in the past. The human costs too are great. 16 million people have lost their homes and land to man-made lakes in India. China will have to move one million people to make way for the Three Gorges dam on the Yangtze, on which construction work began this year. k+s-5#u 

But the solution to the world’s water crisis lies less in supply than in demand. The bank has spent half a century building dams, but the water problem in most countries results mainly from inefficient use of water.

Israeli scientists have long since understood this. They have revolutionized their country’s use of water, cutting out much of the waste in watering crops, which in many countries accounts for 90% of water use.
