This article, based on ethnographic and archival research in the northeastern parklands of the Central African Republic (CAR), explores the area’s history of armed conservation. Critical scholarly accounts of armed conservation practices and projects often starkly contrast the people involved in them: there are agents of the state, or state-like actors, who seek to dominate, territorialize, and discipline, often using violence to do so, and there are local populations who are dispossessed of their lands and resources without compensation and forced into new kinds of poverty, despite rhetoric and practices meant to inculcate “local participation”. The case presented here forces us to re-think these accounts. Rather than pursuing authority in the sense of expanding control over other people, people in northeastern CAR (whether putatively in favor of or opposed to conservation) are working to create and maintain access to the status of an income. To do so they engage in practices of threatening and hiding. While the means to use physical force are not equally shared, capacities to threaten and hide are widely held, and organizational and other hierarchies are unstable, making it difficult to describe any of this as a matter of domination and resistance. Expanding on literature that examines processes of green militarization (Lunstrum, 2014), the article focuses on the interactional dynamics of armed conservation to show that threats are as important as acts of physical violence, and that hiding—whether in the bush or plain sight—is critical to understanding armed conservation in an area where the state is largely seen as absent. 相似文献

The primary role of marine protected areas (MPAs) is marine conservation, however policy and practice around MPAs have not reflected this. The focus on cost-effectiveness by spatial conservation prioritization has led to a bias towards placing MPAs in areas that are least threatened. This study investigates how conservation priorities differ between two management strategies of either targeting or avoiding high threat areas for protection, using the case of the Sulu Sulawesi Seas in the Coral Triangle. For both strategies, the target of protecting 20% of habitat could not be achieved solely by protecting low threat areas. A high proportion of the region had large differences in conservation outcomes between the two strategies; majority of these areas were highly prioritized in the threat avoidance strategy but had low or zero importance in the threat selection strategy. Selecting for highly threatened areas required less habitat area to be protected to achieve the same conservation target and resulted in a more equitable distribution of priority sites per country and sub-region. This demonstrates the importance of deciding on the objectives of conservation and management policies up-front. The results suggest that, contrary to the common practice of avoiding threats in spatial planning, a threat selection strategy should be part of the management toolbox, particularly in transboundary planning for regions with high overall threat levels, where it may be important to achieve shared conservation targets equitably. 相似文献
