This study reviews and evaluates methods and tools used to assess climate change vulnerability and adaptation (V&A) in Cambodia’s Tonle Sap Basin, focusing on water governance and community resilience. Given the region’s susceptibility to floods, droughts, and climate variability, the research emphasises the need for site-specific assessments to in...


This short paper examines existing methods and tools used to understand climate change impacts, local vulnerabilities and adaptive capacities, with a focus on water governance and water use, in three target areas in the Tonle Sap Basin. Assessment of the effects of climate change requires an integrated framework approach. That framework is made up...


This study applies the Water Evaluation and Planning (WEAP) model to assess irrigation management in the Stung Chrey Bak catchment, Cambodia. It evaluates three scenarios—reference, 5 percent annual increase in irrigation demand, and additional reservoir storage—to explore sustainable water allocation strategies. The catchment supports 10,367 h...

This study explores how hydrological knowledge and community participation can enhance decision-making in irrigation water allocation in Cambodia’s Stung Chrey Bak catchment. Conducted under the Water Resources Management Research Capacity Development Programme (WRMRCDP), the research integrates hydrological analysis with participatory learning...
