Urban agriculture — growing food in cities — has benefits far beyond the food it produces. Whether on rooftops or in community gardens, for as long as people have lived in cities they have grown food there.
Urban agriculture has gotten a lot of press in recent years: growing food in the city has a unique, even romantic appeal, upending one’s notions about what is urban and what is rural and providing many social, environmental and health benefits. City farming operations vary in size: from chicken coops and beehives to household, school or community gardens, from rooftop and larger-scale farms to aquaculture facilities and indoor hydroponic “vertical farms”; they may be privately, publicly or commercially-owned; they may be run for profit, operated by a social mission or some combination of the two. 3
In the US, in the middle of a depression in 1890s Detroit, the mayor requisitioned vacant land for unemployed city residents to grow vegetables. The gardens, called “potato patches” (after their primary crop), produced $14,000 worth of produce on 430 acres in the first year, with more than 1,500 families involved at the peak of the program’s popularity. 8 The “busy streets” theory of crime prevention suggests that neighborhoods where residents are taking care of their own streets – as demonstrated through well-tended gardens rather than vacant lots, fixed-up abandoned buildings, new benches and more lighting – have lower crime than neighborhoods without much community involvement. 10
