The Mekong Delta is affected by upstream development – often in ways not fully understood and with uncertain impacts on natural, social and economic systems which sustain life and well being for millions of people in Vietnam. With expanding plans for major developments on the mainstream and its tributaries, those impacts are likely to become much more serious. Vietnam and its riparian neighbours do not have adequate scientific understanding for informed decision making on Mekong mainstream hydropower projects, especially on their downstream effects.
