Under regimes of austerity, social movements´ transformative eco-politics may appear endangered. What kinds of environmentalism and radical imaginaries can unfold in social movements in crisis-ridden societies? I focus on the ‘movement of the squares’ during its post-encampment phase, with a case study of three urban projects of the Indignados movement in Barcelona. Observation of these projects reveals the importance of three common and intertwined radical imaginaries embodied in participants’ social practices and orienting their future visions: the commons, autonomy, and ecologism. The ecologism imaginary cannot be properly understood if disembedded from the other two: the ‘Indignant’ projects constitute community structures re-embedding (re)production, jointly covering and generating needs differently, in response to the global capitalist forces that are threatening their social reproduction. Eco-politics can only be plausibly transformative if it is able to articulate a politics of intersectionality linking social reproduction with ecological interconnectedness and struggles against dispossessions and social injustice.
