Over the years, thousands of climate change adaptation projects have been implemented globally. While there has been substantial scholarship on the extent and nature of adaptation efforts, fewer studies have examined why and how adaptation projects are being resisted. An analysis of resistance to adaptation offers critical insights to scholars and practitioners by recognizing the contentious nature of adaptation pathways and highlighting alternative visions for adaptation. Drawing on 20 case studies identified through a systematic review of the literature, we identify nine insights for research and practice. First, there is little literature on resistance to adaptation, suggesting that it is being underreported. Second, resistance to adaptation is not an anomaly, spanning sectors, actors, and geographies. Third, resistance to adaptation initiatives often has little to do with climate change skepticism. Fourth, the modes and outcomes of resistance are creative and diverse. Fifth, the state plays a critical, but not uniform, role in adaptation and thus resistance. Sixth, formal participation mechanisms can accommodate, neutralize, or facilitate resistance to adaptation. Seventh, the diverse goals of resistance reflect the multiplicity of imagined adaptation futures. Eighth, resistance is generative of material outcomes and novel subjectivities. Ninth, resistance can be costly, fracturing, and ineffective. This review highlights the need to further investigate resistance to climate change adaptation, which should be seen as a site of political struggle between different conceptions of what adaptation is and should be. It also provides insights for identifying maladaptation and pathways toward more emancipative forms of adaptation.
