How does water scarcity threaten the very survival of the Chinese nation

CHINA’S emperors regarded control over water as one of the principal ways of controlling the country. They poured their kingdom’s resources into vast projects such as the Grand Canal between Beijing and Hangzhou, which was finished in about 500AD. The country’s Communist leaders have inherited this passion. Eight of the nine members of the previous Politburo’s standing committee were engineers and a former president, Hu Jintao, was a water engineer. The country has built as many large dams as the rest of the world put together.

The Grand Canal now forms a link in one of the biggest engineering projects the world has ever seen, whose first stage is due to open by the end of this year. It goes by the unlovely name of the South-North Water Diversion Project (see article). If it is ever finished it will move water along 2,000 miles of new canals, some of them across the Himalayan plateau, from the Yangzi in the south to the Yellow River in the north, at a cost of more than $50 billion.
