Land subsidence Mekong Delta

In only 25 years, the Mekong Delta has been transformed from a stable area into a rapidly-subsiding delta. Using a new three-dimensional groundwater model of the entire delta, researchers from Utrecht University and Deltares have shown by how much and where the land is subsiding due to groundwater extraction. The study shows that Vietnam is pumping itself down faster and faster. The rate of subsidence has now reached several centimetres a year, which is a lot higher than the global sea-level rise of a few millimetres a year. That is alarming news for the delta, which is only 1-2 metres above sea level. Salinisation, higher floods risks and coastal erosion are genuine threats. Unless action is taken, this fertile area – which is home to 20 million people and which produces food for almost 200 million others – faces a major catastrophe. The researchers have published 'Impacts of 25 years of groundwater extraction on subsidence in the Mekong Delta, Vietnam', identifying groundwater extraction as a major cause of land subsidence in the Mekong Delta.
