Environmental experts warned that the Mekong Delta would face disaster if sea levels rise due to global warming and climate change.
Meeting in the southern province of Can Tho yesterday to discuss the problem, they said around 40,000 square kilometers of farmland in the 13 delta provinces would again become marshland, with seawater flooding in during high tides.
In Bac Lieu, Ben Tre, Hau Giang, Soc Trang, Tra Vinh, and Vinh Long Provinces, 40-50 per cent of the land would be submerged.
Globally, countries would lose farmlands to seawater and erosion and see many types of organisms lose their habitats and coastal infrastructure threatened.
Delegates discussed how the delta region could cope with the tragedy and suggested measures for the purpose.
They called for increasing public awareness of the impending tragedy and for the government to build river and beach dykes.
They urged scientists to discover rice strains that would grow in brackish soil.
