Summary
Urban agriculture (UA) is an industry located within (intraurban) or on the fringe (periurban) of a town, a city or a metropolis, which grows or raises, processes and distributes a diversity of food and non-food products, (re-)using largely human and material resources, products and services found in and around that urban area, and in turn supplying human and material resources, products and services largely to that area. Urban farms already supply food to about 25% of the world’s urban population. Due to the increased urbanization, UA has become more popular in the past few decades as concerns for the environment, food sustainability and resilience have combined with increased interest in health.
