Nearly 100 hydropower dams are planned for construction along the tributaries and main stem of the Mekong River’s 2,700-mile stretch. The river, one of the world’s largest, flows through Burma, China, Vietnam, Laos, Thailand and Cambodia. It is an economic engine for fishermen and a food source for millions of people worldwide. While the dams are expected to provide clean energy to the region, if not managed properly they also have the potential to offset natural river patterns, which would damage food production, supply and business.
