Nearly half of China’s major cities are skinking because of water extraction and due to the increasing weight of urban buildings and infrastructure, a new study has found. The research, published in the journal Science, discovered that Chinese cities, including Beijing and Tianjin, are facing a “moderate to severe” risk of subsidence. 45% of China’s urban land was sinking faster than 3 millimetres per year, with 16% at a rate of over 10 millimetres per year, the study revealed.
