| Resum: | As the world's population continues to urbanize, cities are uniquely positioned to lead a new wave of agricultural innovation by integrating the productive components of their food systems directly into their infrastructure. This study empirically measures the potential total production of three of the most consumed vegetables that can be attained through rooftop greenhouse (RTG) production in Barcelona. Three production scenarios are posited. Scenarios 1 and 2 are underpinned by a revenue-maximizing logic. While in Scenario 3, production is guided by Barcelonan vegetable consumption. Results show that on 65 ha of rooftop area, or 0. 64 % of the total 101. 4 km2 area over which Barcelona spans, a considerable amount of the vegetables Barcelonans consume could be produced. In illustration, in Scenario 3, a total of 5878 t of tomato, 507 t of bell peppers, and 78 t of lettuce can be produced within RTGs in Barcelona. Moreover, a comprehensive discussion on how to provide the water necessary for this urban horticultural system is also undertaken. Barcelona's food system could be significantly enhanced from implementing RTGs throughout the city. However, the city's citizens need to be consulted about their thoughts about altering the city's skyline to implement such a system. |
