Oil, fisheries and coastal communities: A review of impacts on the environment, livelihoods, space and governance

•Coastal communities remain on the fringes of the promised socio-economic benefits of oil development.•An intersection of four themes characterize the oil-fisheries-livelihoods nexus.•Small-scale fishing communities experience adverse impacts due to reduced access to ocean-based livelihoods.•The compounding pressures include pollution, dwindling fish stock, and overall marginalization.•Future research should focus on gender and cross-sectoral governance and collaboration. A quarter of global oil production comes from offshore fields and about 60% of internationally-traded oil travels by tankers. The relationship between oil, fisheries, and coastal communities is documented primarily through case studies in individual jurisdictions and via the impacts of oil spills. Yet, the implications of oil development for fisheries and coastal communities are much broader. This study provides an extensive review of the effects of oil development in relation to four interconnected themes: 1) the environment, including marine habitats and fish; 2) small-scale fisheries and coastal community livelihoods; 3) coastal and ocean spaces, including disputes over territory and infrastructure; and 4) ocean and coastal governance processes. We map spatial overlaps between the oil sector and small-scale fisheries and point to the frequent displacement of fishers from fishing grounds due to increasing coastal traffic and infrastructure, and the catastrophic effects of oil spills on fisheries and coastal economies. Though the oil sector generally has negative impacts on fisheries livelihoods and coastal communities, these effects and their mechanisms vary across locations, ecosystems, species, and specific activities and groups. Overall, this narrative review provides a comprehensive account of the scholarship to date and points to key themes for future research, including intersections between offshore oil and gender, cross-sectoral governance, and the achievement of Sustainable Development Goal 14. Underpinning all of these challenges and potential solutions is a clear need for stronger integration of social and natural science knowledge, perspectives, and tools.
