LHASA, March 26 -- The government of Tibet Autonomous Region and Chinese Academy of Sciences have agreed to launch a large-scale survey of the Qinghai-Tibet Plateau, 40 years after the first was conducted.

Scientists will set out in June to investigate changes in resources, ecology and the environment on the plateau. Their findings will be used to provide scientific support for environmental protection and economic and social development in Tibet.

New technologies, including drones and satellites, will be employed to cover the whole area and capture more comprehensive and accurate scientific data.

The first investigation was conducted in the 1970s, involving over 50 subjects such as geology, geophysics, botany, zoology and agriculture.
