TAILIEUCHUNG - Current and projected climate change in the Mekong Delta

This article evaluates trends in past and projected future climate change at the Mekong Delta. The study is based on updated observation data gathered up to 2014, and the latest climate change scenarios published by the Ministry of Natural Resources and Environment (MONRE). The results show that the mean annual temperature increased by to C, and annual rainfall increased by 5 basis points to 20% at most observation stations during the years 1958-2014. In comparison to the baseline (1986-2005), temperatures were projected to increase by between to °C in the middle of the century and by between to °C at the end of the century, under the medium scenario (). According to the high scenario of , temperatures likely increased by to 2o C in the middle of the century and to C at the end of the century. Annual rainfall is expected to increase from 10 to 20% in the mid-21st century under both and scenarios; increase of 30% in a part of the northern Mekong Delta under the scenario. | ENVIRONMENTAL SCIENCES CLIMATOLOGY Current and projected climate change in the Mekong Delta Van Thang Nguyen Van Khiem Mai Van Thang Vu Dang Mau Nguyen Vietnam Institute of Meteorology Hydrology and Climate change Received 10 May 2017 accepted 5 June 2017 Abstract This article evaluates trends in past and projected future climate change at the Mekong Delta.

Classification number Introduction The Mekong Delta is the largest river delta in Vietnam located in the Mekong River Basin with a total natural area of about million ha. This delta has a coastline ranging over 700 km contiguous to Cambodia in the northwest to South Vietnam in the east to the East Sea in the northeast to the Pacific Ocean in the south and to the Gulf of Thailand in the west 1 . This region is favourable to marine economic development exploitation aquaculture and consumption and export. The Mekong Delta is the largest agricultural development area in the country contributing .
