The Lower Sesan 2 (LS2) dam is a hydropower project that began operating in 2017 on the Sesan River in Cambodia, 15 miles upstream from the point where it meets the Mekong River. The dam will have a drastic impact on the Lower Mekong region as a whole. Community members near the dam site have organized to stop the project. ERI partners with these frontline communities to demand that the LS2 developers consult local populations and provide remedies when their rights have been violated. ERI provides legal support to a coalition that includes community leaders, the 3S Rivers Protection Network, Mekong Watch, Save the Mekong and other civil society groups.
