Roof gardens, most often found in urban environments are any gardens on the roof of a building. Roof gardens are not only for decorative benefits. Hence, roof plantings may provide food, temperature control, hydrological benefits, habitats or corridors for wildlife. Roof gardens are most often found in urban environments. Further, plants have the ability to reduce the overall heat absorption of the building which then reduces energy consumption.
In terms of urban agriculture rooftop farming becomes more and more important. In an accessible rooftop garden, space becomes available for localized small-scale urban agriculture, a source of local food production. Brooklyn Grange is a commercial organic farming business located on New York City rooftops. They grow vegetables in the city and sell them to local people and businesses. The goal is to improve access to very good food, to connect city people more closely to farms and food production, and to make urban farming a viable enterprise and livelihood.
