Rooftop agriculture (RA) is a building-based form of urban agriculture that includes both protected and nonprotected farming practices, such as rooftop greenhouses as well as open-air rooftop gardens and farms. The use of underexploited urban spaces on buildings for farming purposes is considered a useful strategy for targeting global concerns (e.g., the limitations in food security and land access, impacts of climate change or social exclusion). Research shows that RA can ensure multifunctional benefits at the social, environmental and economic levels while avoiding land use conflicts and additional pressure on urban land. However, there are still some obstacles hindering the full development of RA, such as old urban planning and regulations.
