Greenleaf Communities believes that urban agriculture can be beneficial to the environment, and to the health and wellbeing of community members. The introduction of community gardens may be able to reduce the impact of food deserts in low-income areas and allow residents greater access to nutritious food that is necessary to live a healthy life.
Community gardens can mitigate some of the problems that plague urban areas. They can be a beneficial addition to many communities by increasing the availability of nutritious foods, strengthening community ties, reducing environmental hazards, reducing food miles and creating a more sustainable system.
Community gardens can help reduce negative environmental impacts by promoting sustainable agriculture; reducing food transportation costs and reducing water runoff. Humans, plants and animals can all benefit from urban agriculture since it creates habitats and improves the ecology of the area.
- Help improve air and soil quality 
- Increase biodiversity of plants and animals
- Reduce “food miles” that are required to transport nutritious food
- Can replace impervious structures and improve water infiltration 
- Can reduce neighborhood waste through composting 
- Positively impact the urban micro-climate 
Poor nutrition and obesity are both challenges to low-income neighborhoods. Low accessibility to nutritious foods can cause health problems to residents located in food deserts. The addition of gardens to these areas may improve nutrition and increase the consumption of fruits and vegetables.
- Increase access to fresh foods
- Improve food security 
- Increase physical activity through garden maintenance activities
- Improve dietary habits through education
- Increase fruit and vegetable intake
- Reduce risk of obesity and obesity-related diseases
- Improve mental health and promote relaxation 
Social ties are important to the wellbeing of people in a community since they can bring positive health effects and community involvement. Community gardens allow for the creation of social ties and build a greater feeling of community. These connections help reduce crime, empower residents and allow residents to feel safe in their neighborhoods.
- Gardens in urban areas are positively correlated with decreased crime rates 
- Vacant lands can lead to crime which can detrimentally impact the health of residents
- Residents in areas with high crime rates may experience cardiovascular disease and mental health disorders
- The consequences of vacant lands are decreased property values, drug use, and the illegal dumping of litter, tires and chemicals 
- Gardens can improve economic opportunities by training volunteers and selling food at farmers’ markets 
- Urban agriculture can teach residents useful skills in planning, food production and business
- Improving vacant lots increased property values in New Kinsington, Philadelphia by 30% 
Gardens have been an important aspect of many cultures in history. In the past, community gardens were commonly used to provide food for families year-round. During WWII, victory gardens were an important source of food for American families. Recently, there has been a resurgence of community gardens to help mitigate the impacts of food deserts and as a use for the increased number of vacant lands present in urban areas. Community gardens can provide fresh, healthy produce for residents and allow them to reduce their food bills. 
Many cities and organizations provide opportunities for residents to become involved with community gardens. The USDA’s Cooperative State Research, Education and Extension Service has implemented a grant program to help decrease the impact of food deserts in low-income communities. They strive to provide long-term food security by supporting local agriculture projects while also improving economic, social and environmental problems. For successful programs, it is important that the community becomes involved with the project and to work with the community to develop solutions. Soil contamination and acquiring land can become a challenge in implementing a community garden.
The Chicago Park District along with People’s Gas help provides resources to community gardens. These gardens rely on volunteers and include both native edible and ornamental plants. The program supports close to 70 gardens in parks across Chicago.
The Chicago Botanic Garden is also offers urban agriculture opportunities for students and adults to receive training and work on maintaining urban gardens: http://www.chicagobotanic.org/community/
