PHNOM PENH: Cambodian fisherman Tin Yusos tucks into a meal of the previous day's catch with his wife and granddaughter aboard a boat which doubles as their home moored by the banks of the Tonle Sap River.
Experts blame hydropower projects, sand mining, deforestation, wetland conversion and climate change for dramatic drops in water levels in the region's rivers, severely disrupting fishing and threatening food supplies for millions. Marc Goichot, an expert on the region's waterways at the World Wide Fund for Nature , said dams and sand mining in particular can contribute to a loss of fish."Basically the entire system is under stress and changing," he said."We need to address the root causes of those changes and re-establish the key processes like movement of fish."
