Water management has always been a big thing in China.  This morning I read about the South-North Water Project, in which China is starting to divert huge quantities of water from the sub-tropically wet south-west of the country, moving it to the arid north and north-east.

The project is not without human cost, as this article Migrants bear sacrifice for China's south-north water diversion project from China's own news agency shows.

This article China redirects trillions of gallons of water to arid north from the Daily Telgraph is even more bearish about the difficulties.
