Although vertical farming is a very effective way of using unused space, it is also seems difficult to put into practice. Using rooftops makes it a little more achievable, and even more important; it can be put into practise on a very small scale. It is an almost perfect spot for growing crops as the roof is horizontality, has an openness to sun and air and an natural supply for water.
Many projects can be found. An example is the one named the fifth street farm project. The Fifth Street Farm Project has it all: It addresses childhood obesity, stormwater runoff, and climate change. Conceived by a grassroots organization of teachers, parents, and green-roof advocates, the project’s plan calls for a roof farm atop the Robert Simon Complex, a massive public school building on the Lower East Side that houses elementary schools P.S. 64 and the Earth School, as well as the Tompkins Square Middle School. The Fifth Street Roof Farm will grow only a very small portion of the food served in the cafeteria, but it should play an important role in educating young taste buds. “The challenge was doing a green roof at a school and marrying it to this idea of a farmable roof,” said Arad. “You could do an extensive green roof here quite easily and walk away. But it wouldn’t engage school children like a roof farm can.”
Such projects still inspire me to set up a mini rooftop agriculture spot for myself. Self grown food must be so very rewarding if all the ingredients are so close at hand: soil, runoff water from the roof and many friends of family having seeds or seedlings from their vegetable gardens. I can see no reason not to do it.
