Bringing together cutting-edge studies into a range of contemporary sites of urban concern, this volume unfolds the collective research agenda of urban cosmopolitics in three directions: the relational constitution and political effects of urban technologies, infrastructures, and other material-semiotic agencies (agencements); the coming together of new urban concerns, constituencies, and publics (assemblies); and the coalescing of urban practices into shared spaces of co-existence, life-support, and survival (atmospheres). Together, we assert, this exploration of urban cosmopolitics amounts to a 'strong program' of urban studies, allowing us to shed new light on key topics of contemporary research, including urban planning and citizen publics; economic dynamics and constraints; street life and the everyday; built environment dynamics and differentiations; and disasters, risks, and sustainable transitions.
