Technopolitical Natures draws on conceptual insights from feminist theory, critical race theory, queer theory, political ecology, and critical science studies to explore the politics of technoscience, material natures, and socio-environmental justice. We consider the intimate ways that matter and knowledge are politically animated and inextricably bound up in everyday configurations of social life, as well as struggles over sovereignty, public space, and citizenship. How do processes of materialization – of toxins, of waste, of resources, etc. – come to matter for political and social formations? How are these very processes inseparable from simultaneous reconfigurations of (human and nonhuman) bodies, as well as the environment broadly construed? How might this shape our conception of the “matter” of matter and its supposed fixity? And what are the political stakes of these decisions?
