This review engages with literature on authoritarian populism, focusing specifically on its relationship to the environment. We analyze hybrid combinations of authoritarianism and populism to explore three themes from the literature: environmental governance, social and political representations of nature, and resistance. In the environmental governance section, we analyze how governments have increasingly resorted to populist politics to expand extractivism; certain commodities with national security implications have become key commodities to be protected; and borders, frontiers, and zones of inclusion/exclusion have become flash points. In the social and political representations of nature section, we analyze settler colonialism and sacrifice zones as organizing principles for relations with the environment. In our final section on resistance, we review literature highlighting pushback to authoritarian populism from peasant, indigenous, and worker movements. Variants of populism and authoritarianism are likely to persist amid increasing competition over resources as components of responses to environmental and climate crisis. Expected final online publication date for the Annual Review of Environment and Resources, Volume 47 is October 2022.
