Urban agriculture or urban farming refers to activities that facilitate food production, primarily for sale, in urban environments. Many for-profit urban agriculture ventures use vertical farms, hydroponics, aquaculture, greenhouses, and other efficient systems to maximize the productivity of small spaces. Urban agriculture activities frequently take place on small areas of land such as median strips, rooftops, courtyards, and balconies, and can include edible landscapes, front yard or rooftop gardens, window farming, and hanging plant gardens in home or community settings (Bellows 2004). Aquaculture and livestock ventures in US cities are growing (Golden 2013), but remain less common than in other countries (Brown 2000).

Evidence of Effectiveness

Urban agriculture is a suggested strategy to increase access to fruits and vegetables and build more sustainable, self-reliant local food systems (CDC-Urban agUSDA-Merrigan 2011Clark 2013Grewal 2012FAO-Food for cities, Bellows 2004, Golden 2013). Urban agriculture is also a suggested strategy to reduce hunger and obesity (CDC-Urban ag, USDA-Merrigan 2011, Clark 2013). Models suggest that many US cities may be able to achieve near self-reliance for fresh produce, poultry, eggs, and honey (Grewal 2012) and case studies suggest that many small scale projects in an area can increase food security overall (Clark 2013, Grewal 2012, Bellows 2004, Golden 2013). However, additional evidence is needed to confirm effects.

Urban agriculture activities may reduce fossil fuel energy used to produce, process, and transport food, and diminish urban heat island effects (CDC-Urban ag). In some cases, urban agriculture activities provide entrepreneurial opportunities, which have been associated with increased income for participants (Kaufman 2000, FAO-Food for cities), as well as greater levels of local business incubation, skills training, and job creation (Golden 2013).

Municipal zoning policies can support urban agriculture activities by designating agricultural districts or specifying certain agricultural uses that are permitted or conditionally approved (Mukherji 2010). Some urban agriculture sites may contain contaminated soil and require remediation before beginning activity (Wortman 2013). Price, location, food culture, or lack of interest may also be challenges to successful urban agriculture; mobile food carts or farm stands, marketing foods with taste tests and cooking demonstrations, and youth mentorship may help remove barriers to purchasing healthy food produced by urban agriculture (Hu 2013).

Organized urban agriculture projects are often located in low income, inner city neighborhoods (Kaufman 2000, Golden 2013), which may reduce disparities in access to healthy foods such as fresh fruits and vegetables.


United States

Many non-profit organizations support urban agriculture efforts, for example, Cultivate Kansas City, which supports a network of farms (CKC), and Keep Growing Detroit (KGD-GID). Some urban agriculture non-profits such as Growing Power in Milwaukee (GP-WI), Greensgrow in Philadelphia (Greensgrow-Urban farm), and Growing Green Urban Farm in Buffalo (MAP-Urban ag) include compost, vermicompost, aquaponics, and livestock on their farms along with outreach efforts such as farmers markets, mobile markets, community supported agriculture and education programs.

The Detroit Black Community Food Security Network works to build self-reliance, food security and justice in Detroit's Black community through urban agriculture activities and other efforts (DBCFSN-Urban ag). In West Oakland, California, City Slickers Farms provides training, tools, soil tests, and supplies to encourage urban farming and backyard gardening (CSF-Sustainable food). Weavers Way Coop in Philadelphia, PA sells a lot of fresh produce from their own urban farms in Northwest Philadelphia (WWC-Our farms). Plant Chicago, in an old meatpacking plant (Plant Chicago), and Farmed Here, an indoor, organic, vertical farm (Farmed Here), are two examples of indoor urban farms.

State and local legislation can support urban agriculture initiatives. California enacted legislation in 2013, for example, that allows cities and counties to create incentive zones in urban areas for local food production, providing land owners a property tax break for urban agriculture or community gardening activities. Tennessee and West Virginia also enacted legislation addressing infrastructure barriers and liability concerns related to community gardens (NCSL Winterfeld-Obesity prevention 2014). Municipal policies and zoning plans in Seattle (Seattle-Urban ag), Boston (BRA-Urban ag zoning), and Somerville, MA (Somerville-MUAI); and city government agency activities in San Francisco (SF DOE-Urban ag) and Boston (Boston-Urban ag) are examples of local efforts to support these initiatives.
