The hidden potential of urban horticulture

Abstract

Urban areas offer considerable potential for horticultural food production, but questions remain about the availability of space to expand urban horticulture and how to sustainably integrate it into the existing urban fabric. We explore this through a case study which shows that, for a UK city, the space potentially available equates to more than four times the current per capita footprint of commercial horticulture. Results indicate that there is more than enough urban land available within the city to meet the fruit and vegetable requirements of its population. Building on this case study, we also propose a generic conceptual framework that identifies key scientific, engineering and socio-economic challenges to, and opportunities for, the realization of untapped urban horticultural potential.
