Six provinces in Vietnam’s Mekong Delta region have been scrambling to battle the severe erosion of the sprawling river and coastal network, with some areas now requiring “urgent measures”, state media said on Tuesday. The provinces, Long An, An Giang, Dong Thap, Ben Tre, Soc Trang and Ca Mau, have either declared emergencies or cordoned off long stretches of land on the Mekong’s edge because of the erosion, the official Vietnam News Agency (VNA) reported.
