Global efforts to conserve nature and prevent biodiversity loss have intensified in response to planetary-scale challenges—nowhere more so than in coastal regions. Accordingly, international conservation organizations have increased their efforts to promote marine protected areas as one of the interventions to prevent biodiversity loss in global hotspots. Focusing on the human element of marine conservation and the extractive industry in Tanzania, this volume illuminates what happens when impoverished people living in underdeveloped regions of Africa are suddenly subjected to state-directed conservation and natural resource extraction projects, implemented in their landscapes of subsistence. draws on ethnographically rich case studies and vignettes collected over a ten-year period in several coastal villages on Tanzania’s southeastern border with Mozambique. In seven chapters, the book demonstrates how state power, processes of displacement and dispossession, forms of local resistance and acquiescence, environmental and social justice, and human well-being become interconnected. Written in lucid, accessible language, this is the first book that reveals the social implications of the co-presence of a marine park and a gas project at a time when internationally funded conservation initiatives and extraction projects among rural African populations are engendering rapid social transformation.
