China and the Cascading Geopolitics of Lower Mekong Dams
Much has been written on the downstream impact of China’s dams on the Lancang-Mekong River, which flows through or along the borders of five other countries after exiting China. Most of the discussion relates to the hydrological impact of impounding water in the eight dams along the mainstream Lancang Jiang in Yunnan Province. Particular concern surrounds the recently completed Xiaowan Dam and the recently approved construction of the Nuozhadu Dam, each of which is of a scale to impound quantities of water that can affect river hydrology throughout the basin. The Lancang Cascade, as it is termed, has caused considerable controversy in downstream countries, most notably during the 2008 floods and the 2010 drought. Both the floods and the droughts were blamed by many in Thailand, and some in Laos, Cambodia and Vietnam, on China’s actions. Recent articles on the downstream implications of altered river hydrology and the need for China to be less disingenuous in its public relations over the issue show the confluence of river hydrology and geopolitics in an international river basin such as the Lancang-Mekong.
