The "Eat Your Way to Better Health (EYWTBH)" is a garden-based nutrition education program conducted and evaluated for three years in Indiana third-grade classrooms, aiming to educate youth about food sources and healthy eating habits. Participants started and maintained their own school gardens during the 8 to 12-week implementation, with outcomes assessed using pre- and post-program questionnaires. Results indicated that upon program completion, youth reported higher healthy food choice self-efficacy and increased variety in fruit and vegetable consumption.

This study, conducted from September 2012 to August 2013 with 490 respondents in Accra, Ghana, assessed knowledge and awareness of wastewater use in urban agriculture. It found low awareness of irrigation water sources among consumers and street food vendors, and low health risk awareness among farmers, despite high awareness among salespersons and consumers. Crucially, consumers did not prioritize health indicators when purchasing produce, and farmers' health risk awareness did not influence their adoption of safer practices.

This study evaluated the health risk of heavy metals (Cd, Cr, Cu, Ni, Pb, Zn) in soils from 14 urban community gardens in Baghdad City, Iraq. The non-carcinogenic hazard index (HI) was below the threshold (HI < 1), indicating no non-carcinogenic hazard. However, the carcinogenic risk index (RI) for Cd, Cr, and Ni exceeded the unacceptable threshold (RI < 1 × 10−4), demonstrating a serious carcinogenic risk for children and adults in the study area.

A Post-Occupancy Evaluation (POE) was conducted on a community garden project in Conchal, São Paulo, Brazil, implemented through a public-community alliance. The study, involving residents with plots in the garden, observed positive impacts such as improved quality of life for participants, enhanced social integration and participation, and an increased sense of belonging to the neighborhood. This type of urban intervention was concluded to have the potential for positive reverberations on directly involved users, the urban territory, and their relationship.

A systematic review of 40 articles on school gardening programs found that quantitative research was generally of poor quality, with limited evidence for changes in fruit and vegetable intake based on self-report. Qualitative research, though of better quality, attributed a range of health and well-being impacts to school gardens, but more robust quantitative research is needed to support these findings.

This study used a quantitative questionnaire to assess the impacts of an urban school garden program on 31 middle school students enrolled in an agriscience connections course in the United States. Data analysis revealed that the cultivation aspect of the program had the greatest positive outcome on urban middle school youth. Students with a family garden showed greater interest in participating, and culinary activities were highly enjoyed, with over 60% agreement on all related items.

Mujtaba Baqar, Nadia Jamil, Naveed Ahsan, Kiran Khanum, Abdul Qadir, Mariyam Zameer, Anam Khalid · Transylvanian Review · Pakistan (Lahore)

This case study investigated the impacts of heavy metals from wastewater irrigation on soil, groundwater, and leafy vegetables (Indian mustard, spinach, fodder) in the Charrar Drain catchment, Lahore, Pakistan. Samples were collected from seven sites. Drain water showed Cd, Cr, and Pb concentrations exceeding limits at most sites, and groundwater Cd concentrations also exceeded limits, though Cr and Pb were within permissible ranges. Soil samples contained Cd, Cr, and Pb, and leafy vegetables irrigated with wastewater showed varying heavy metal concentrations, indicating a heavy metal bioaccumulation issue that may exceed threshold limits.

Masdjidin Siregar · Jurnal Agro Ekonomi · Indonesia (Jakarta)

This paper describes intensive peri-urban leafy vegetable agriculture in Jakarta, which utilizes idle land and provides employment and income for rural migrants. However, the prospect of this agriculture is unclear because it uses non-agricultural land that will eventually be developed. The study concludes that government assistance in credit, extension, and research is needed, and alternative lands for cultivators must be found.

This cross-sectional survey investigated the relationship between access to green space and health outcomes (stress, general health) among 406 adults in four highly deprived urban communities in Scotland, United Kingdom. Social isolation and place belonging were the strongest predictors of stress in three communities and of poor general health in the fourth. The amount of green space in the neighborhood, particularly access to a garden or allotment, was a significant predictor of stress, while physical activity, frequency of winter green space visits, and views from home predicted general health.

This paper proposes reframing the issue of soil lead contamination and urban gardening in shrinking cities from a potential conflict to a potential solution. Many shrinking cities face high soil lead burdens from their industrial past and the historic use of lead-based paint and leaded gasoline, which is often seen as a barrier to urban agriculture. The paper argues that urban gardening can be a solution to the soil lead problem through soil management, including soil testing and the addition of amendments, and through social network and community building.

This chapter explores the potential for creativity across a wide range of life domains, including the arts, social work, and cooking. It notes that poverty and lack of funds are not necessarily an impediment to people expressing their creativity in their places of living. Community gardens can bring together parts of a community who might not otherwise have anything to do with each other, in addition to providing gardeners with physical and mental health benefits.

This study investigated food insecurity screening among clinicians in Vermont, where 76% of residents experience some level of food insecurity. It found that physicians and physician assistants prefer using an established two-item screen for food insecurity. However, these clinicians tend to underestimate the actual prevalence of food insecurity in their practice communities.

This exploratory study examined three urban cultivation sites in New York, London, and San Francisco to assess their nutritional, ecological, and social sustainability contributions. Field analysis revealed very low food outputs relative to the populations of their catchment areas, indicating that most urban food will continue to come from outside urban peripheries. The study concluded that urban food growing's sustainability benefits are more social than agronomic or ecological.

In Chicago, semi-structured interviews and plant inventories were conducted with 59 African American, Chinese-origin, and Mexican-origin households regarding ecosystem services and tradeoffs in their home food gardens. A total of 387 plant species were identified; gardens of African American households were rich in ornamental species, while those of Chinese-origin households had a depauperate flora. Shade trees and a developed shrub layer were absent from most gardens, suggesting a tradeoff in ecosystem services favoring food production. Only 9.6% of the inventoried species were native to the Chicago area.

Monroy Quevedo, Katherin Mayerli · · Colombia (Bogotá)

A mixed-methods study in UPZ Marruecos, Rafael Uribe Uribe Locality, Bogotá, Colombia, investigated the impact of urban agriculture on the food and nutritional security of participating families. Based on interviews and surveys with 10 participants, urban agriculture was found to contribute to families' food and nutritional security by increasing the availability of safe food and improving physical access. Participants perceived higher consumption of vegetables, fruits, tubers, cereals, and legumes, leading to greater dietary diversity.

Community garden activities play a significant role in bridging formal and informal learning, especially in urban children's science and environmental education, by promoting relational methods that integrate food security, social interactions, community development, environmental activism, and cultural integration. An auto-ethnographic study revealed that community garden-based practices adhere to forms of agency such as embracing diversity, sharing power, and trust building as part of everyday learning.

Prince Antwi-Agyei, Adam Biran, Anne Peasey, Jane Bruce, Jeroen H. J. Ensink · BMC Public Health · Ghana (Accra)

This cross-sectional study in Accra, Ghana, assessed faecal exposure among 80 farm workers during dry and wet seasons, analyzing water and soil samples for E. coli. The results showed that while irrigation water was highly contaminated (5.6 Log E. coli/100 ml), exposure to farm soil (2.3 Log E. coli/g) was the key risk pathway due to soil-to-mouth events, with 53% of farmers experiencing such events daily. The estimated norovirus infection risk to farmers was found to be higher than guidelines set by the WHO, indicating that exposure to soil is a critical pathway of pathogen risk in wastewater farmers, exceeding recommended health targets.
