BEIJING, Aug. 23-- China invested a total of 30 billion yuan (4.87 billion U.S. dollars) on water infrastructure projects in the Tibet Autonomous Region in the last two decades, data from the Ministry of Water Resources showed on Saturday.

More than 1,000 projects have been organized by the ministry since China initiated a program to aid the region about 20 years ago.

The facilities provided safe drinking water for 2.39 million people, and the works also brought electricity to about 360,000 herdsmen, said the ministry.

The area of farmland under irrigation in Tibet is over 3 million mu, or 200,000 hectares.
