In this paper we develop a relational understanding of populism informed by urban political ecology. We argue that an urban political ecology of populism is necessary for a popular-democratic denunciation of the environmental claims of the far right. This article thereby aims to further develop a critique of liberal environmentalism and right-wing populism. We do so by first staging a dialogue between literatures in urban political ecology and Gramscian inflected readings of populism. Both have sought to interpret how spatial – and ecological – claim making becomes central to struggles over hegemony. The second half of the paper analyses these tensions in the Dutch farmers movement, which has become one of the most important political forces in the Netherlands since 2019. Abstracting “the local”, “the rural” or “the farm” out of the broader processes of urbanisation is central to struggles over the representation of farmers. Right-wing movements thus seek to further a broader disillusionment with formal politics, while effectively deploying spatial and ecological abstractions that pit the “rural” against the “urban”. We conclude by instead emphasising the crucial connections between populism and ecology, and call for a popular-democratic political ecology.
