In Vietnam’s Mekong Delta, home to about 17 million people, large areas of land have been poldered for the cultivation of crops such as rice and shrimp. At the moment, the delta is on average less than a meter above sea level. But due to accelerated land subsidence, mainly caused by groundwater extraction, a shortage of river sediment, and rising sea levels, researchers from Wageningen University & Research and Utrecht University predict that by 2050 large parts of the delta will have fallen below sea level if nothing changes soon. What can Vietnam do to stay above water?
