Because groundwater pumping capital China Beijing every year “sags” by 11 centimeters, which in the future may pose a real threat to him. This is the conclusion members of the Chinese Academy of Sciences Chen Xiaoyang and Li Mi, as well as a Spanish engineer Robert Thomas.

The researchers concluded that the capital of China fairly quickly and steadily falls to the Earth by studying the satellite images. In all likelihood, this process is due to the fact that the soil under the city year after year, is actively pumped ground water, which are then Try Us, including for agriculture and other needs. As a result, water that accumulates under the Beijing thousands of years, is running out, and under the pressure of city soil begins to wrinkle like a dry sponge, writes The Guardian.

in the future, they fear scientists, “underground” dive Beijing could become one of the main threats to the city and its inhabitants -. in particular, this process is fraught with the collapse of buildings. In this regard, the researchers strongly recommend that the Chinese authorities to limit pumping of groundwater at the legislative level. It is reported that control mechanisms for the production of water in the country already exist, but do not apply too active.
Experts remind that in 2015, China has been developing a project to create a channel of about 2.4 thousand kilometers in length, in which Beijing would be flushed with water. Can this water again “nourish” the ground beneath him, braked subsidence of the city, the researchers are not yet sure.
On its findings the scientists reported in the pages of a scientific journal Remote Sensing.
