This paper critically examines theories of accumulation, dispossession and exclusion for analyzing the agrarian transformations that result from contemporary large-scale land acquisitions across the Global South. Building upon Marx's primitive accumulation, Harvey's accumulation by dispossession and Hall et al.'s Powers of Exclusion, conceptual lenses are developed through which to examine how land grabs transform property and social relationships of resource-based production. I examine the concession of 10,000 hectares by the central government of Laos to a Vietnamese corporation for extracting timber and planting rubber in the southern province of Attapeu. This acquisition has excluded farmers from land and resources that constituted their primary sources of (re)production, reconfigured rural property relations, altered the peasant relationship to land and produced new exploitative forms of wage labor.
