Urban Farm DB summary
This study investigated the supply potential and impacts of four roof mosaic scenarios for local food, energy, and water production systems on urban rooftops in Cerdanyola, a 58,000-inhabitant town in the Barcelona metropolitan area. Using spatial analysis, metabolism analysis, and impact assessments, the study found an average rooftop/household potential of 31 m2, with single-family housing showing the highest potential for electricity (51%) and water (14%) self-sufficiency. Housing estates achieved the highest vegetable self-sufficiency (32%), while rooftop farming systems showed the best performance for housing estates and originary fabrics in terms of overall impacts.
