Health Factors  
Community in Action

A community garden is any piece of land that is gardened or cultivated by a group of people, usually for home consumption. Community gardens are typically owned by local governments, not-for-profit groups, or faith-based organizations; gardens are also often initiated by groups of individuals who clean and cultivate vacant lots. Local governments, non-profits, and communities may support gardens through community land trusts, gardening education, distribution of seedlings and other materials, zoning regulation changes, or service provision such as water supply or waste disposal1.

Evidence of Effectiveness

There is some evidence that community gardens improve access to and consumption of fruits and vegetables2, 3, 4, 5, 6, 7, 8 and increase physical activity for gardeners5, 9. Community gardens are a suggested strategy to improve food security2 and increase fruit and vegetable availability in food deserts10, 11, 12, 13, 14. Experts suggest community gardens may also promote healthy eating, reduce obesity15, 16, 17, 18, and improve participants’ mental health and social connectedness19, 20. However, additional evidence is needed to confirm effects.

Gardening is considered moderate-intensity aerobic exercise and heavy gardening is vigorous and muscle-strengthening exercise21. Community gardening may encourage an overall healthy lifestyle by promoting physical fitness, strength, flexibility, and social engagement, and improving cognitive function among participants, especially older adults9, 22. Community gardening can increase daily fruit and vegetable consumption for adults, teenagers8, and children3. Compared with non-gardeners, gardeners may be more likely to meet recommendations for daily vegetable consumption23. One survey of food insecure gardeners in rural Appalachian Ohio associates gardening with increased produce consumption, better eating habits, increased physical activity, decreased food spending, and increased social capital24. In a Salt Lake City-based study, gardeners had a lower body mass index (BMI) than their non-gardening neighbors15. Community garden participants also appear to value healthy food harvests, cooking meals, and sharing their harvest with family and friends2.

Community gardens can reduce barriers to healthy food associated with transportation, cost, and food preference25, 26, and may increase food security27. Community gardening may also reduce emissions from fossil fuels used to produce, process, and transport food28, 29, 30, and may reduce the energy intensity of an individual’s diet if more plant-based foods are consumed in place of animal products28.

Successful community gardens may have broad neighborhood benefits such as increased nearby property values, increased community engagement and pride, and improved safety25, 31, 32, 33, 34. Community garden participation is associated with increased levels of social capital, neighborhood engagement, and satisfaction19, 35. Interviews with gardeners in Lincoln, NE suggest community gardens may help develop a sense of belonging and connection with cultural identity, social community, and local environment, and improve food security and nutrition, including benefits for individuals who identify as immigrants36. A New York City-based study of community gardens after Hurricane Sandy suggests the gardens may serve as places of social support, collective efficacy, and resilience during and after natural disasters37. Interviews with Latino community gardeners in New York suggest that gardens can host social, educational, and cultural events, and in some cases, promote local activism38. By providing an opportunity to plant culturally meaningful foods in a social setting, community gardens may also increase community engagement and improve nutrition among resettled refugees26, 39.

Since residents maintain the land and space often comes from vacant abandoned lots, community gardens are relatively inexpensive25. Placing community gardens in low income areas can reduce disparities in access to healthy foods, especially fresh fruits and vegetables11, 40. Community gardening can also reduce food costs for participating families40, 41. Among households with lower incomes, a higher percentage of community garden space is typically devoted to food production and culturally relevant crops, instead of ornamental plants or recreation space42.

Funding, participation, land, and materials, including water access, are typical challenges for community gardens43. Experts suggest city policies can establish and secure gardeners’ land32 such as integrating community gardens into urban park systems44. Experts recommend cover crops to improve soil quality and nutrients, soil testing and guidance, perennial plants to provide habitats for non-pest insects, and educational programming and technical support in multiple languages to encourage participation and maximize yields from community gardens42. Gardeners can produce high value, high yield harvests especially when planting vertically grown crops, such as tomatoes and peppers41

Impact on Disparities

No impact on disparities likely

Implementation Examples

Numerous municipalities support community gardens. For example, Seattle has integrated some gardens into parks via city policies and interdepartmental agreements44 and its P-Patch program uses a community land trust to acquire and preserve land, provide educational programming, and distribute materials such as seedlings and compost45. The San Francisco Community Gardens Program is run by the city on city-owned land46. Several municipalities have partnerships with land banks that donate property or help develop community gardens, as in Columbus, OH47 and Shelby County, TN48.

In 2013, renewed in 2017, California enacted legislation allowing cities and counties to create incentive zones in urban areas for local food production, providing land owners with a property tax break for urban agriculture or community gardening activities49. Tennessee and West Virginia also enacted legislation addressing infrastructure barriers and liability concerns related to community gardens50.

Community gardens often grow out of public and non-profit partnerships. For example, Grassroots Gardens of Western New York stewards 110 community gardens, and is applying to become the first accredited Community Garden Land Trust with the Land Trust Alliance51. Chicago NeighborSpace community land trust is authorized to purchase vacant land to preserve it for gardens52 and the Detroit Garden Resource Program works toward a city where the majority of fruits and vegetables consumed by residents are grown within the city limits53. The Boston Natural Areas Network works to preserve urban green spaces, including community gardens54. A 2015 study identified 110 hospital or health center-affiliated community gardens in the US55.

Additional examples of organizations sustaining community gardens include: Nuestras Raíces in Holyoke, MA56; City Harvest in Philadelphia, PA57, 58; and the Summer Sprout community gardening program in Cleveland, OH59. The New York City Community Garden Coalition is an example of an organized group of gardeners using education, advocacy, and grassroots organizing to preserve and create community gardens60. Community Crops coordinates gardens in Lincoln, NE, offers gardening plots on a sliding fee scale, as well as training and technical assistance to beginning, immigrant, and limited-resource farmers61. Community gardens can also be sustained in rural areas and smaller municipalities; for example, Community Food Initiatives supports five community garden locations in Athens County in southeastern Ohio62.
