Cambodia and other countries in the lower Mekong region should delay any decisions about initiating hydropower projects for 10 years to allow for further research of potential impacts, according to a long-awaited environmental assessment study.
“Due to the uncertainties regarding scale and irreversibility of risks in such a complex river system ... decisions on mainstream dams should be deferred for a period of up to 10 years, with reviews made every three years to ensure that the necessary conditions to strengthen understanding of the natural systems as well as management and regulatory processes are conducted effectively,” said a statement that accompanied the study.
Tiffany Hacker, an interim communications adviser for the Mekong River Commission, which represents Cambodia, Laos, Thailand and Vietnam, said the recommendation for a delay was based on numerous “guidelines that essentially say there needs to be more supporting information, and that the potential impacts are not clear”.
“The full scale of the irreversible risks are still uncertain based on the information that [consultants commissioned by the MRC] were able to gather for the strategic environmental assessment,” she said.
