As large as 79,000 square kilometers of land has dropped more than 200 millimeters, Zhang Zuozhen, vice-president of China Geological Environmental Monitoring Institute, told CCTV. The subsidence mainly occurs at the Yangtze River Delta, North China and plain areas covering North China's Shanxi province and Northwest China's Shaanxi province, he said. The lowering of ground is mainly caused by excessive exploitation of underground water, which has led to damage of buildings, bridges, underground pipelines and dysfunction of urban drainage system, according to the report. The State Council has approved a plan of preventing land subsidence from 2011 to 2020, which was jointly created by several ministries and commissions including Ministry of land and Resources.On February 19, the State Council approved China's Land Subsidence Prevention Project, an endeavor that has been revised by ten ministries, according to officials.
Guan Fengjun, director of geological environment department of Ministry of Land and Resources, said the main method to control land subsidence is to prevent underground water from dropping. The report said some cities have taken strict measures to limit collecting underground water. In Xi'an, capital of Northwest China's Shaanxi province, more than 1,000 wells have been sealed after 150 square kilometers of land dropped more than 200 millimeters since 1959. Shanghai, located at the Yangtze River Delta is recharging underground water through 121 wells with more than 60,000 tons every day. - ECNS.
According to research, more than 50 counties in China are slowly sinking. Experts compare land sinking to a chronic disease, that goes unnoticed but remains dangerous. More than 50 county-areas in China are suffering from land subsidence, while the total area of land lower than 200 millimeters has reached 79,000 square kilometers. Parts of the cities may be submerged under water in the future. The areas which have the most severe situations are the Yangtze River Delta, the North China Plain and the Fen-Wei basin. According to the China Geological Survey, in the past decades, the economic losses caused by land subsidence in the Yangtze River Delta have totaled up to 315 billion yuan. The economic losses of the North China Plain amount to 332.8 billion yuan. - Global Times.View more images and the complete video of the land subsidence HERE.
