| Abstract |
The external resource dependency of urban areas results in the externalization of environmental and socioeco-nomic impacts. Implementing food, energy and water production systems on urban rooftops (roof mosaics) can potentially help cities become more self-sufficient but depends on the city's urban morphology. We studied the supply potential and impacts of four roof mosaic scenarios for different urban forms in Cerdanyola, a 58 thousand-inhabitant town in the metropolitan area of Barcelona. We combined spatial analysis of potential rooftops, metabolism analysis, and social and environmental impacts. The municipality has an average rooftop/ household potential of 31 m2 on which to implement any of the mosaic scenarios, with the highest potential in the single-family housing typology. The highest level of vegetable self-sufficiency was found in housing estates (32%), and the lowest in originary fabrics (28%). Regarding electricity and water self-sufficiency, the highest self-sufficiency level was found in the single-family housing typology (51% and 14%, respectively) and the lowest in housing estates (26% and 8%, respectively). Regarding impacts, the implementation of the electricity and rainwater harvesting systems depicts the most positive indicators in single-family housing areas. However, for housing estates and originary fabrics typologies, the best performance is shown to be in the implementation of rooftop farming systems. |
