Last June 29th, ROCK was invited to debate ‘the role of urban farming in the future of the city’ with the local communities at the Marvila Library, ROCK intervention territory in Lisbon. The workshop, organised by Serve the City Portugal, under the BIP-ZIP project ‘Cool’arte Crescente’ and chaired by the architect, researcher and curator Joana Braga, aimed at debating around the ideas of urban farming as a space of socialisation, as a key for activating memories and generational cultural practices, and as a driver for sustainable production and consumption. ROCK ICS-UL team members Chiara Pussetti and João Mourato discussed the role of local knowledge and practices of former and current farmers in the Marvila area, the relation between this intangible heritage and the current vision of urban farming as key for urban sustainable development, and its importance for the future of the territory.
