How does climate change transform how we read, write, tell and teach urban histories? Drawing on ongoing ethnographic and documentary film research in and on the neighborhood of Caju, in Rio de Janeiro’s port region, the presentation will explore the challenges and potentials of narrating the city and its production from the perspective of its multiple waters. I will do so by elaborating the theoretical underpinnings and empirical findings of the pilot web based documentary film project Águas do Caju. This collective and collaborative project weaves together different historical narratives of how this formerly imperial elite neighborhood, squeezed between a massive complex of cemeteries, two expressways and kilometers of land reclaimed from the sea to support port logistics and infrastructure, became a metropolitan sacrifice zone.
