Mekong Delta loses half of silt to upstream dams: scientists

A soft shield of silt that took over 6,000 years to form and which protects the ‘rice bowl’ of Vietnam against intrusion from seawater, erosion and declining groundwater levels has been seriously stripped by Chinese dams on the Mekong River, say experts. Half of the river’s essential sediment is now trapped upstream and the delta may be in jeopardy of disappearing altogether. Thanh Nien News reports.
