The Mekong Delta is one of the three deltas in the world that are most vulnerable to climate change, while worsened weather conditions have seriously affected this region. Climate change has caused a rise in sea levels, with droughts and floods happening more frequently in the Mekong Delta. Sea level rises will cause many existing freshwater plains areas to become brackish water areas while changing the hydrographical behavior of the river current, putting pressure on 90 percent of all flooded areas. It is predicted that in the next several decades, sea level rises will cause flooding in the vast majority of the Mekong Delta that is already flooded annually. This will lead to a big loss in agricultural land. Declining water resources will severely affect agricultural production and the fishery industry. Salinity in cultivated areas will become more and more serious in the coastal provinces of Ca Mau, Bac Lieu, Soc Trang, Tra Vinh, Ben Tre, Tien Giang and Long An and it will cause freshwater shortages in the region. The warming up of the earth affects natural ecological systems, changes temperature margins of continental and marine eco-systems as well as the structure of fauna and flora in a number…
