This article examines the nature of conflicts over natural resources in the postwar period in Sussundenga district, Mozambique, as contextualized within a broad history of natural resource management in Mozambique from the colonial period through the postindependence and war years to the present day. The evidence suggests that the notion of a simple transition from wartime conflict to postwar sustainable development needs revision. Instead, some patterns and practices of resource use predated the war and have outlasted it, some began and ended with the peace agreement, and others accelerated or were initiated after the end of armed hostility. Throughout these periods, there have been social conflicts between and within different groups of resource users at all levels. Armed conflict did change patterns of resource use in some respects, but the result was not entirely negative for the natural resource base; forest resources in some areas actually regenerated during the war years. These conclusions build on arguments in environmental history and political ecology demonstrating that there is no deterministic relationship between humans and the natural environment. Rather, there is a range of possible interactions depending on locally varying contexts as well as broader social and political structures.
