Integrated Water Resources Management Project

active

The Integrated Water Resources Management Project will be aligned with the following impact: Cambodia's water resources management made climate-adaptive and sustainable to support social and economic growth and protect ecosystem. The project will have the following outcome: livelihoods in the target river basin groups made climate and disaster resilient through climate-adaptive integrated water resources management. The project will focus on the river basin groups covering rivers Moung Russey, Pursat, Sanker, and Svay Don Keo located in Pursat Province and Battambang Province in the southwest of the Tonle Sap Lake. These river basins were assessed as highly vulnerable to limited available water due to climate change impacts. In the target basin groups, expected changes to precipitation and temperature patterns will result in higher temperature and evapotranspiration and more rainless days in dry season, which will increase water demands in various sectors in dry season. Substantial increases in wet season rainfalls are also expected, increasing the risk of both riverine and lowland flash flooding events. The potential for increased peak water levels at the Tonle Sap Lake further exacerbates this risk.
