"The Water resources of China include 2,711.5 cubic kilometers of mean annual runoff in its rivers and 828.8 cubic kilometers which was pumped annually from shallow aquifers circa 2000. As pumping water draws water from nearby rivers, the total available resource is 2,821.4 cubic kilometers. 80.9% of these resources are in the Yangtze River Basin. In 1993 498,720 square kilometers were irrigated."@en .
