Regions pouring billions into water conservation

Guiyang/changsha - Local authorities throughout China are intensifying their efforts to conserve water, which experts have seen in the past as a weak point that has damaged the nation's sustainability.

The central government pledged in its No 1 document issued at the beginning of this year that it will invest 4 trillion yuan ($612 billion) in water conservancy during the next 10 years. The No 1 document is a summary of the government's priorities.

In the document, the government urged local authorities to set aside 10 percent of their revenue accrued from land sales for farmland water conservation projects.
