Benefits of community gardening: what the evidence says

Community gardens are often credited with better diets, stronger neighborhoods and greener cities. Some of those claims are well supported and others are harder to measure. Here is what the evidence and government sources actually say.

Food and nutrition

One of the most cited studies surveyed 766 adults in Flint, Michigan. Adults in households where someone took part in a community garden ate fruits and vegetables 1.4 more times per day than those who did not, and were 3.5 times more likely to eat them at least five times daily.^[1] The study was a cross-sectional phone survey, so it shows an association rather than proof that gardening caused the difference. People who already eat well may be more likely to garden.

Neighborhood and social benefits

A 2010 review in the Journal of Community Practice reviewed published research on community gardening in the United States. It analyzed 55 studies and found recurring themes that included health, food security, economic development, youth education, open-space preservation, beautification, social relationships and community empowerment. The authors also noted that much of the research was qualitative and called for more rigorous studies.^[2] Gardens give neighbors a reason to meet, share skills and take part in local decisions.

Environmental and land benefits

The EPA notes that turning brownfields, vacant lots and abandoned structures into gardens and farms can increase property values, remove environmental hazards, improve soil and reduce stormwater runoff. It adds that gardens can connect cultures, encourage healthy eating, teach useful skills and increase outdoor physical activity, especially where there is no nearby park.^[3]

Learning and youth

School and youth gardens are a common teaching tool. GRO1000’s 2015 people’s-choice winner, for example, was a children’s sensory garden in Detroit designed as an outdoor classroom.^[4] National nonprofits such as KidsGardening fund youth garden programs for this reason.^[5]

Limits and trade-offs

• Soil safety: benefits depend on safe soil. The EPA recommends researching site history and testing before growing food.^[6]
• Measurement: many studies are small or rely on self-reported data, so results vary between places.
• Time and land security: gardens on borrowed land can be lost when the site is redeveloped, which is why written agreements matter.

How to make benefits more likely

Gardens that reach their goals usually have secure land, a reliable water supply, clear rules and a core group of organizers. Donating surplus produce, offering accessible beds and running workshops widens who benefits. Start with our step-by-step guide.
