The Nam Tha Hydropower Project is located in the far mountainous northwest of Laos. It would require the resettlement of around 9000 mostly indigenous people from 1,379 households in 34 villages, most of whom are ethnic minority people. It would also impact downstream communities along the Nam Tha River and the mainstream Mekong. This project is going to define the village-level impact scope of hydropower projects in Laos with the case of Nam Tha Dam. The main strategy is to create an “archive of livelihood sheds” over time, as well as suggesting this as a new form of impact assessment (“Assessment via itinerary” ) of Nam Tha Dam in nearby rural areas. This counter-mapping strategy with Landaccount device and website will identify the complexity of the contexts of villages in the reservoir area and empower indigenous groups to fight against the technical system.
