The Mekong River and the Tonle Sap Great Lake form a vital ecological and economic system in the region, supporting rich biodiversity and the livelihoods of millions. However, decades of upstream development, overfishing, and weak resource management have degraded the system, resulting in declining fish stocks and increasing risks to agriculture—especially in Cambodia’s floodplains. The “Mekong–Great Lake Diversion” Project aims to enhance early-season water inflow into the Tonle Sap at the beginning of the wet season, after the lake has fully drained. This will support timely fish migration and help reduce risks to early rice crops. Through hydrological assessments, ecological studies, hydrodynamic modeling, and infrastructure planning, the project promotes integrated floodplain development, strengthens national food and water security, and fosters regional cooperation under the Mekong–Republic of Korea partnership.
