IS PART OF GHINA SINKING?

 

Yes, large parts of China, especially major coastal cities like Shanghai, Tianjin, and Beijing, are experiencing significant land subsidence (sinking) due to heavy groundwater extraction, the immense weight of buildings from rapid urbanization, and natural geology, creating a serious crisis that increases flood risks and threatens infrastructure, with projections showing millions could live below sea level by 2120 if trends continue. 

Key Reasons for Sinking

·         Groundwater Depletion: Pumping excessive water from underground aquifers leaves empty spaces, causing soil to compact and the land to sink.

·         Weight of Buildings: China's massive construction boom adds significant pressure, especially in cities built on soft sediments.

·         Geology: Delta regions, where many cities are located, are naturally prone to sinking due to soft, thick sediments. 

Major Affected Cities

·         Tianjin: Has some of the highest subsidence rates, with over 89% of its area sinking significantly.

·         Shanghai: Has sunk up to 3 meters in the last century, though groundwater control measures have helped in some areas.

·         Beijing: Also severely affected, with some districts sinking rapidly. 

Consequences & Risks

·         Infrastructure Damage: Buildings, roads, and sewage systems are damaged, as seen with street collapses in Tianjin.

·         Flooding: Sinking exacerbates sea-level rise, putting coastal cities at higher risk of severe flooding.

·         Population at Risk: Projections suggest millions of coastal residents could be living below sea level by 2120.
