China's water crisis

If you don't have it you can sell it - or bill for it. And if it's not clean, consumers may not want it anyway. Business Week reports that over the past year getting clean water has been a struggle for many in China. In February one of the most severe droughts to hit China in a half-century affected some 5 million people and 2.5 million livestock in the provinces of Hebei and Henan, near Beijing. Farther south in Yancheng, Jiangsu, 300 kilometers from Shanghai, more than 200,000 people were cut off from clean water for three days when a chemical factory dumped carbolic acid into a river. Just before the Olympics last June, the coastal city of Qingdao, site of the sailing events, saw an explosion of algae in nearby waters that may have been caused by pollution.

These are hardly unusual in China. The country that has a long history of devastating floods and droughts arguably faces an even bigger water crisis today. After almost 30 years of double-digit economic growth and the migration of hundreds of millions of villagers to the cities, China has been barely able to meet the spike in demand for water. Its resources were scarce to begin with and pollution has made clean water even scarcer. Another unknown: the effect of climate change. "Based on our country's basic water situation, [we] must implement the strictest water resource management," said Vice-Premier Hui Liangyu at a national water conference in Beijing in January.
