In New York City urban farming and roof-top farming is no novelty. But since changes in zoning law have been considered and implemented by the city, urban farming has emerged from a niche development to a larg-scale phenomenon.
As Nicole Baum, the spokeswoman for Gotham Greens points out: “These large-scale greenhouses are advanced and expensive, but more and more consumers and businesses are supporting them”, meaning that also large-scale investments are needed to foster local production of foodstuff. As rooftop greenhouses are attractive, also landlords consider them as a potential amenity and opportunity for profit.
As costs being the largest obstacles for roof-top farming, many of the initial start-ups had to be financially supported to be profitable.
