The report shows that the trend of recent climate change in Viet Nam is beyond the level of natural change. Temperatures have increased by 0.05-0.20?C and sea level has increased by 2-4 cm per decade in the last 50 years. According to projections, by the end of the 21st century, the annual temperature in Viet Nam will increase by between 1.1-1.9?C and 2.1-3.6?C rainfall is likely to increase by 1.0-5.2% and 1.8-10.1%, and sea level is likely to rise between 65 and 100cm, in comparison with the period 1980-1999, under low and high emission scenarios respectively. The potential impacts of climate change for the seven climatic zones of Vietnam are likely to be different, but are likely to be critical in the water resources and key socio-economic sectors such as agriculture, forestry, fishery, energy, transportation and health. Vietnam is currently developing a low carbon economy and mitigation policies aimed to reduce the GHG emissions in these sectors. It is also developing a number of strategies to adapt to the impacts of climate change so as to reduce the vulnerability of society.
