The Sekong River Basin

The Sekong River Basin is an important trans-boundary tributary to the Mekong River shared by Cambodia, Lao PDR, and Viet Nam. It is known for notable for its rugged topography and large forested areas.

This 28,816 km2 watershed lies to the north of the Sesan and Sre Pok River Basins. Collectively, these three basins are known as the 3S Basins, and form the largest and most important trans-boundary watershed of the Mekong River, contributing up to 20% of the Mekong’s annual discharge and 15% of its life-giving sediment. The 3S Basins are also a bread basket for over three million people, many of whom depend directly on the resources provided by the rivers.

As the Asian region develops, and given the basin’s high irrigation and hydropower potential, the 3S rivers are expected to continue playing a significant role in the economic growth of the basin, and the region as a whole. But this important basin also faces many threats. Rapid development in recent years has led to changes in land cover, water resources, and environmental services.

Collaborative trans-boundary governance is central to the sustainable and efficient use of water resources in the 3S Basins.

IUCN, under the umbrella of the Building River Dialogue and Governance (BRIDGE) project supported by the Swiss Agency for Development and Cooperation (SDC), seeks to facilitate cooperative processes in the 3S region by developing and strengthening water governance capacities through governance reforms, stakeholder dialogues and knowledge exchange programmes.
