Mekong Basin

The Mekong River is one of the world’s great river systems, flowing 4,909 km through six countries: China, Myanmar, Thailand, Lao PDR, Cambodia, and Viet Nam. The source of the river’s great productivity is its seasonal variation in water level and the range of wetland habitats inundated. The Mekong River Basin’s biodiversity is immense, even in comparison with other parts of tropical Asia. Its biodiversity is fundamental to the viability of natural resource-based rural livelihoods of a population of 60 million people living in the Lower Mekong Basin.
