Rooftop farms sit at the dynamic intersection of hyper-local food supply and green infrastructure. Aside from the unparalleled opportunity to maximize access to local food, while at the same time reducing the transportation costs and food miles, urban agriculture offers a number of other environmental benefits that include -- temperature control, control of combined sewage overflow, and habitat for wildlife. Not only does this open options for fresh and nutritious foods in food-scarce areas, it can also help to jump start a more localized food economy.
