The Mekong is one of the world’s great rivers. Covering a distance of nearly 5,000km from its source on the Tibetan Plateau in China to the Mekong Delta in Viet Nam, the river flows through six countries: China, Myanmar, Thailand, Lao PDR, Cambodia and Viet Nam. Its basin is home to one of the richest areas of biodiversity in the world, with more than 20,000 plant species and 850 fish species discovered to date. An estimated 80% of the nearly 65 million people living in the Lower Mekong River Basin depend on the river and its rich natural resources for their livelihoods, making sustainable development crucial for the environment and communities living in the basin.
