Hydropower development and environmental impact assessments in Vietnam: current practice and shortcomings

Hydropower projects play an important role concerning national energy security in Vietnam; however, the boom in hydropower development in the last ten years had caused many negative impacts on the environment, fisheries, and people’s livelihoods at upstream and downstream river basins, revealing certain weaknesses the management of systems, processes and projects. The main objectives of Environmental Impact Assessments (EIAs) are to reduce environmental impact and to be a supporting tool for decision-making processes. However, this study finds that EIAs of small and medium scale hydropower projects in Vietnam did not assess thoroughly the important factors such as water balance changes, deforestation, aquatic production impacts, and cultural impacts on the indigenous population.
