A major driver of change in the Mekong River basin relates to hydropower development and the consequent changes in landscape and natural resource access regime that it induces. In this paper, we examine how the livelihoods of resettlers evolve following resettlement, and examine the determinants of that process. The study takes place in the context of the Theun Hinboun Expansion Project in Lao PDR. Based on longitudinal household surveys conducted before resettlement as well as 1, 2, and 3 years after resettlement, we identify the process of livelihood adaptation in resettled communities.
