The USAID Mekong ARCC Climate Change Impact and Adaptation Study quantifies specific shifts in climate and hydrology factors for the Lower Mekong Basin by 2050, and projects some of the likely impacts to agriculture and other important livelihood sectors resulting from future changes to the basin's hydroclimate.

By 2050 the extent and distribution of daily maximum temperatures will differ significantly from the Lower Mekong Basin's historical trends. Some areas of the basin, particularly the eastern plains of Cambodia and parts of the Central Highlands of Vietnam, will see increases between 3°C to 5°C. Such a dramatic temperature rise will seriously impact the livelihood, health, and food security prospects of communities of the Lower Mekong.

By 2050 the extent and distribution of rainfall will differ significantly from the basin's historical trends. Annual precipitation is forecast to rise throughout the Lower Mekong Basin by anywhere from 35 mm to 365 mm, with the largest increases occurring in the northern Annamites mountain range in cental Lao PDR. Larger and more frequent storm events and heightened flooding are anticipated for the Mekong mainstream and its tributaries.
