Proposed Mekong dam will destroy fisheries
A Chinese-backed plan for Cambodia to build the Mekong River’s biggest dam would destroy fisheries that feed millions and worsen tensions with Vietnam, which has most to lose from dams on the waterway, said a threeyear study commissioned by the Cambodian government. The report, posted this month on the website of the US-based organisation that conducted the study, said the Sambor dam would “generate large power benefits to Cambodia, but at the probable cost of the destruction of the Mekong fishery and the certain enmity of Vietnam”. The dam would block fish migration in what scientists say is the world’s most productive freshwater fishery. It would also prevent riverbed sediment from fertilising the Mekong Delta rice bowl. Cambodia’s government has not commented on the report.
