Alexandra Grace Lancey · · United States (Florida)

This ethnographic study in Pinellas County, Florida, investigated school gardening efforts at Title I elementary schools, focusing on an organization that installs gardens in "failing" schools. The research found that strict public school standards and neoliberal education reform paradoxically prevent teachers and administrators from fully utilizing school gardens for nutrition education. This limits their effectiveness in discussing nutrition, healthy eating, and local food, as the focus shifts to state-regulated education standards, revealing significant infrastructural challenges.

Diogo José Amorim de Almeida, Dilamar Dallemole, Arturo Alejandro Zavala Zavala · Revista Ibero-Americana de Ciências Ambientais · Brazil (Varzea Grande)

This study analyzed the urban and peri-urban horticultural production structure in Varzea Grande, Mato Grosso, Brazil, using an exploratory empirical and bibliographic approach followed by Cluster Analysis of primary data from local producers. Despite contributing to food production and maintaining disease-vector-free land, the research found that this activity is in decline. Its low profitability and challenging commercialization process make it unattractive or merely a supplementary income, as small productive forces struggle to sustain themselves against the current market structure and unfavorable social policies.

Araceli Calderón Cisneros · Dialnet (Universidad de la Rioja) · Mexico (Chiapas)

This qualitative study analyzed the role of family urban agriculture in urban sustainability in San Cristobal de Las Casas, Chiapas, Mexico, using open and structured interviews. The visited agricultural systems showed characteristics favoring resilience and sustainability, such as low use of external inputs and recycling of domestic waste. However, a limitation found was that the contribution of own production to family consumption is very low, despite existing food, environmental, and socio-cultural motivations for its continuity.

David J. Bettez · · United States (Kentucky)

During World War I, President Woodrow Wilson appointed Herbert Hoover as head of the US Food Administration to promote food conservation and increase production. In Kentucky, Fred Sackett served as federal food administrator, implementing programs like “meatless” and “wheatless” days, encouraging housewives to use substitutes and children to grow school gardens. The federal government also established a Fuel Administration, headed in Kentucky by Wiley Bryan, who encouraged fuel conservation and increased production, and attempted to ensure equitable coal distribution during the 1917-1918 winter shortage.

This study examines the integration of garden-orchards into public spaces in Oaxaca de Juarez, Oaxaca, from the perspective of landscape as the insertion of aesthetic and utilitarian green areas in growing and changing cities. It argues that sustainable green areas like urban gardens enhance social and spatial integration, improving socio-economic aspects. The research aims to understand how implementing garden-orchards in public spaces generates or rehabilitates urban environments and their potential as green infrastructure.

Galdino Xavier Paula Filho, Gutemberg Armando Diniz Guerra · Cadernos de Agroecologia · Brazil (Altamira)

This study analyzed alternative vegetable production systems in nine urban gardens in Altamira, Pará, Brazil, focusing on methods avoiding agrochemicals and chemical fertilizers, and their commercialization in two local open-air markets. Semi-structured interviews and on-site visits revealed that pest and disease control uses natural repellents like pepper, tobacco, neem, and garlic compounds. Fertilization relies on wood sawdust, crop residues (rice and coffee straw), and animal manure. Commercialization is linked to social organization and occurs through producer associations at open-air markets.

A program at Penn State Medical Center's farmers' market and community garden integrated medical student mentors with nutritional education for four families with overweight/obese children. Two families completed all visits, spending an average of 32 minutes per visit, with expenditures of $40.68, and reporting one weekly produce item unused. The program was found feasible and beneficial for participating families, students, and vendors.

Starecheski, Amy · · United States (New York City)

This chapter examines the contested nature of value, urban citizenship, and property claims through the study of squatting, urban homesteading, and community garden activism in the South Bronx, New York City. It highlights how squatters' initiatives, while challenging neoliberal privatization, could also be coopted into a discourse of individual responsibility in a neoliberalizing city. The research explores how squatters claimed a right to the city based on their labor and citizenship, and used history and property rights to redefine their urban presence amidst renegotiated meanings of debt and homeownership.

This interdisciplinary pilot study in St. Louis, Missouri, USA (2013-2015) investigated relationships between pollinator health and urban land-uses. Wild bees were sampled weekly at urban farms, community gardens, and prairie pockets, and ethnographic interviews were conducted with 30 decision-makers in summer 2015. Informants described bees' role in crop yield and reported planting to attract pollinators, suggesting the city is viable for pollinator habitat.

Amy Laura Cahn, Paula Z. Segal · ˜The œFordham urban law journal/Fordham urban law journal · United States

This paper argues that the invisibility of community-stewarded spaces, such as community gardens, within urban governance frameworks in North American cities leads to their enclosure and loss. It highlights that marginalized residents often have the least acknowledged claim to urban space. The study suggests that making existing community-stewarded places visible and exposing pathways to access is crucial to prevent enclosure and promote equity.

In Belo Horizonte, the "Productive Garden" project, launched in 2008, promoted urban agriculture and food security. From 2009 to 2011, it integrated into the "From Seed to Table" program, encouraging urban farmers to sell vegetables to the institutional school meal market. Based on action research, the project enhanced farmers' technical and organizational capacity, resulting in public schools procuring vegetables from "Productive Garden," an experience that remains active. This experience demonstrated that urban agriculture is economically viable and contributes to food security.

Rashawn Ray, Dana R. Fisher, Carley Fisher-Maltese · Du Bois Review Social Science Research on Race · United States (Washington, DC)

This study analyzed quantitative data on fifth graders' math, reading, and science standardized test scores in Washington, D.C., to investigate how school gardens help close the achievement gap. It compared academic performance between students in traditional schools and garden-based learning schools, and examined whether the presence of a school garden reduces race and social class disparities in academic achievement. Findings showed that the presence of a school garden is associated with higher test scores in reading and science, and this association persisted even when controlling for students' race and class composition.
