Cambodia is home to diverse and vital waterscapes that play a key role in its ecology, culture, and economy. The country is dominated by the Mekong River, one of the longest rivers in Asia, which flows through its heart and supports millions with its rich biodiversity and fertile floodplains. The Tonlé Sap Lake, Southeast Asia’s largest freshwater lake, is another iconic waterscape. It dramatically expands during the rainy season, creating a unique flood-pulse system that supports vast fisheries and floating villages. Together, these waterscapes sustain agriculture, fishing, and transportation, while also shaping Cambodian traditions and ways of life.
