Abstract

The Don Sahong Hydropower Project (DSHPP), located in the Khone Falls area of Khong District, Champasak Province, southern Laos, near the border with Cambodia, has been amongst the most controversial hydropower dams in the Mekong River Basin. Despite considerable regional and international opposition, the dam was finally constructed, becoming commercially operational in 2020. In 2011, I expressed serious concerns about the project's potential impacts on long-distance migratory fish and associated fisheries, especially fish that migrate from Cambodia and Vietnam up the Mekong River to Laos and Thailand. However, my concerns have somewhat changed along with the circumstances, although they continue to focus on dam impacts on migratory fish. I am now particularly concerned about the indirect impacts of the DSHPP on the fishing livelihoods in the Khone Falls area, and the impacts of the dam on fish larvae and fish passing through the dam's turbines when migrating downstream. Using a political ecology approach, this paper considers how infrastructure, in this case a large hydropower dam located on the Mekong River, has altered the spatialities associated with the project in particular ways.
