A  roof garden is any garden on the roof of a building. Besides the  decorative benefit, roof plantings may provide food, temperature  control, hydrological benefits, architectural enhancement, habitats or  corridors for wildlife, and recreational opportunities. In an accessible  rooftop garden, space becomes available for localized small-scale urban  agriculture, a source of local food production. An urban garden can  supplement the diets of the community it feeds with fresh produce and  provide a tangible tie to food production.
