This article identifies the potentialities of urban agriculture in Pirapozinho, São Paulo, focusing on food and economic use. Based on field research and interviews, the study found that urban agriculture provides quick access to quality products and fosters close farmer-consumer links. However, it also found that urban agricultural practices have not received due governmental attention at national or local scales, despite their potential.

This study analyzed technical-productive and socioeconomic limitations to urban agriculture adoption within the Urban and Periurban Agriculture Network (RAUP) in Xalapa, Veracruz, Mexico. Based on 25 questionnaires from active members and 10 from sporadic participants, both groups agreed that the main constraints are socioeconomic, such as lack of space and limited free time, which are linked to urban lifestyles. Technical-productive limitations were not considered relevant.

Guadalupe Del Ángel-Lozano, Martha Elena Nava-Tablada · Tropical and Subtropical Agroecosystems · Mexico (Xalapa)

This study analyzed technical-productive and socioeconomic limitations to urban agriculture adoption among members of the Network of Urban and Periurban Agriculture (RAUP) in Xalapa, Veracruz, Mexico. Researchers applied 25 questionnaires to active members and 10 to non-practicing participants. Both groups of RAUP participants identified socioeconomic factors, such as lack of space and limited free time due to urban lifestyles, as the main constraints, while technical-productive limitations were not considered relevant.

M. A. McKenna, Jessica Wall, Suchitra Roy · · Canada

This chapter summarizes the status of plant-based food initiatives in Canadian schools. While considerable progress has been made in establishing school gardens, youth leadership programs, and food sustainability education, researchers note that more work is needed to reach all students, offer programs addressing all aspects of food literacy, and achieve system change.

Survey data from 142 gardeners and urban farmers in the Twin Cities Metropolitan Area, USA, characterized phosphorus (P) and nitrogen (N) inputs and harvest, and measured soil P concentrations at a subset of sites. Median application rates were 300 kg P/ha and 1400 kg N/ha, with low nutrient use efficiencies (2.5% for P, 5.0% for N). Garden soils had a median Bray P value of 80 ppm, far exceeding recommended levels, indicating a buildup and potential loss of P and N. Urban gardens, though only 0.1% of land area, constitute one of the largest inputs of P to the watershed.

Catherine Dobbins · Journal of the Arkansas Academy of Science · United States (Arkansas)

This mixed-method needs assessment in Arkansas investigated urban agriculture, using interviews with 16 urban farmers and a quantitative survey of County Extension Agents (CEAs) with a 57% response rate. Farmers expressed varied needs, and while they viewed the Cooperative Extension Service (CES) positively, CES lacked specific resources for small-scale sustainable farming. The survey revealed that 70.2% of CEAs reported low or nonexistent concentrations of urban farming in their counties, indicating potential barriers for agents to work with urban farmers.

This article describes the obstacles to implementing public policy for family agriculture in urban areas of Brazil. Representations associated with rural-agricultural concepts have shaped the classification criteria of rural technical assistance technicians, limiting the policy's application in urban settings. Social movements in Rio de Janeiro highlighted the lack of access for urban family farmers to agrarian policies, leading to the recognition of urban family agriculture as a public problem.

Lindsay K. Campbell, Erika S. Svendsen, Renae Reynolds, Victoria Marshall · Social & Cultural Geography · United States (Rockaway, NY)

This study used Actor Network Theory to explore the material and social dynamics of a coastal community garden on public housing grounds in Rockaway, NY, after Hurricane Sandy. Three assemblages with different governance arrangements—tidal shore, garden plots, and treed lawn—were identified. However, "unruly" actors and actants, including people, saltwater, poison ivy, dogs, and trash, were found to spark controversy and resist governing.

Carrie Chennault · Iowa State University Digital Repository (Iowa State University) · United States

This three-year feminist ethnographic study examined the Growing Together Iowa community donation gardening and food rescue program, focusing on its institutional and community partners. The research aimed to understand how solutions to food insecurity emerge from social relations and socio-historical contexts. Findings demonstrated that uneven power relations permeate even well-intended efforts to address food insecurity within such initiatives.

Blaire O’Neal · · United States (San Diego County)

This research investigates the significance of soil in distinguishing urban agriculture forms in San Diego County and examines how soil-based and soilless growing methods relate to justice. The results illustrate that while the way food is grown is important for urban agriculture organizations' identity and practices, it is only one of many factors influencing justice, such as socio-spatial context. Justice is an ongoing process that evolves as urban agriculture commodities travel through their circuits and interact with placed networks filled with intentions, actions, discourses, objects, actors, and forces.

Peter R. W. Gerritsen, Víctor Sanchez Bernal, Georgina Torres Rodríguez · Brazilian Journal of Development · Mexico

This study analyzed food security in two medium-sized cities in Western Mexico using secondary data and field research. It found that while these highly globalized cities had a low degree of food security, extensive domestic backyard agricultural activities significantly raised family-level food security. A critical finding is that this potential for urban food security is not valued by governmental institutions.

Glenda Maria Braga Abud, Maria Lúcia Bahia Lopes, Rosália do Socorro da Silva Corrêa, Ruth Helena Cristo Almeida · Revista em Agronegócio e Meio Ambiente · Brazil (Benevides)

A descriptive survey was conducted with 25 producers in Benevides municipality, Pará State, Brazil, to analyze the contribution of flower and ornamental plant production to local development. The activity was found to be essentially subsistence-based, with low articulation among producers and technological and productive limitations. These aspects resulted in a restricted capacity to contribute to development in the studied municipality.

Joshua Sbicca · · United States (Colorado)

This study investigated the potential for urban agriculture to drive green gentrification, using Denver, Colorado, as a case study. Urban agriculture was shown to drive gentrification and act as a force for displacement, even when advocates are aware of its exclusionary potential for urban farmers and residents. The research argues that political economy and cultural forces create neighborhood disinvestment and economic marginalization, and urban agriculture contributes to green gentrification through a process of revalorization that exploits rent gaps.

Thomas Earl Tracy · ODU Digital Commons (Old Dominion University) · United States (Virginia)

This study investigated reasons for the low enrollment of African Americans in urban agriculture degree programs in Virginia, which contributes to few African Americans in leadership positions in the urban agriculture industry. Data were collected through surveys and interviews with agriculture students, non-agriculture students, and department chairpersons at Virginia State University and other colleges. The findings indicate a dearth of African Americans enrolled in these programs.

Martin Jayo, Eduardo de Lima Caldas · kult-ur revista interdisciplinària sobre la cultura de la ciutat · Brazil (São Paulo)

A study in São Paulo, Brazil, examined recent forms of appropriation of the urban agriculture agenda, using a historical analysis of urban agriculture practices by Caldas and Jayo (2019). It was observed that traditional urban agriculture discourses have been captured by new actors, including parts of the public sector opportunistically appropriating the theme and the real estate market promoting an imitation of urban agriculture as a marketing tool.

A Noussia · Research Open (London South Bank University) · Brazil

This paper discusses urban agriculture on city peripheries within a scenario of urban expansion, focusing on the Guaratiba neighborhood in Rio de Janeiro. It argues that the city's urban expansion process does not invest in the inclusion of urban agriculture activities within the area's socio-environmental dynamics.

Candis M. Hunter, Dana Williamson, Melanie Pearson, Eri Saikawa, Matthew O. Gribble, Michelle C. Kegler · Local Environment · United States (Atlanta)

This study used five focus groups with Atlanta community garden leaders to investigate perspectives on composting, hygiene, and mulching, which are practices to reduce exposure to soil contaminants. Gardeners cited a need for more funding, volunteers, and training. A primary barrier to composting and mulching was concern about contamination of source materials, and participants did not directly link these practices to reducing soil contaminant exposure. Hygiene challenges included concerns about beneficial bacteria, inadequate water access, and limited supplies.

Joeli Silva de Souza, Ryzia de Cássia Vieira Cardoso, Lídice Almeida Arlego PARAGUASSÚ, Sidione Ferreira dos Santos · Revista de Nutrição · Brazil (Salvador-Bahia)

A cross-sectional exploratory study in Salvador-Bahia characterized community gardens, with five out of seven gardens participating and data collected from 13 horticulturists. 80.0% of gardens lacked land legalization, 100.0% operated without technical support, and 60.0% had no social organization. Major difficulties included lack of funding, volunteers, and water use restrictions, indicating insufficient policies limited technical support and financing.

Shawna Holmes · Canadian Food Studies / La Revue canadienne des études sur l alimentation · Canada

Interviews with school food environment staff across Canada examined how provincial nutrition regulation changes affected food procurement. While the regulations opened opportunities to improve nutrient content and involve local producers or school gardens, some schools struggled to procure nutritionally compliant food because of higher costs of transporting produce to rural, remote or northern communities and logistical problems such as spoilage. Regulations improved food environments in some schools, but others still require more support.

Annelise Caetano Fraga Fernandez, Almir Cezar Baptista Filho · Cidades, comunidades e território/Cidades comunidades e territórios · Brazil

This article describes the obstacles to applying Brazil's family-farming public policy in urban settings. It shows that a set of representations associated with rural agriculture has shaped the classification criteria used by rural technical-assistance (ATER) staff, and that this in practice limits how the policy can be applied in urban areas. It states that the mobilization of social movements linked to urban agriculture, specifically in the municipality of Rio de Janeiro, led to the construction of an initiative, but the available abstract breaks off at that point.

Micajah Daniels, Courtney Coughenour · Digital Scholarship - UNLV (University of Nevada Reno) · United States

This project uses Black Feminist Health Studies as an interdisciplinary approach to analyze the holistic impacts of community gardens on nutrition behaviors. It demonstrates, through a Socio-Ecological Wellness Wheel, that the implementation of green spaces such as community gardens correlates with both benefits and unintended negative consequences, including green gentrification, and proposes this audit tool as a way to empirically measure garden quality and the nutrition environment affecting fruit and vegetable consumption among food-insecure populations.

Focusing on community gardens in Metro Vancouver, British Columbia, Canada, particularly in the city of Richmond, this study (2019) sought to clarify how urban agriculture's development is accompanied by the "commodification of rural space." It finds that Metro Vancouver's urban agriculture differs from suburban agriculture in that community gardens prioritize maintaining green and leisure space within the urban environment over agricultural production for food supply. The study concludes that community gardens function as a node connecting "urbanity" and "rurality," existing in the metropolitan periphery through a commodification of rural character for urban leisure use — that is, their role as green/leisure space for urban residents takes precedence over their function as actual food production.

Mary Anne Martin · Canadian Food Studies / La Revue canadienne des études sur l alimentation · Canada

This article revisits a case study of Durham Integrated Growers (DIG), an umbrella organization supporting urban agriculture in Durham Region, Ontario, Canada, through feminist theoretical framings of knowledge, work, power, care, and community. It states that community-based food initiatives, which strive to provide alternatives to dominant food production practices, are often constrained by limited access to financial, labour, time, and political resources, and notes that the feminization of urban agriculture initiatives in Canada -- despite parallels to what has traditionally been dubbed "women's work" -- has received little attention in the academic literature. Prior research on DIG revealed themes involving the need for community expertise to be recognized, the role of public policy, the effects of relying on unpaid labour, and the centrality of building community.

Nathan McClintock, Christiana Miewald, Eugene McCann · · North America

This chapter explores urban agriculture (UA) as fundamentally political practices, examining its role in neoliberal governance and sustainability policy-making, and as an object of contestation. It relates UA motivations and practices to processes of urbanization and political economic restructuring. The chapter highlights that UA is a site of political contestation, arising from broader political economic shifts.

Juliana Maantay, Andrew Maroko · International Journal of Environmental Research and Public Health · United States (New York City)

This study examined whether proximity to community gardens in less affluent neighborhoods is associated with an increased likelihood of gentrification, using Brooklyn, New York as a case study. Employing GIS and spatial analysis, the results suggest that proximity to community gardens is associated with significant increases in per capita income over a five-year period. This indicates that environmental improvements, such as community gardens, may paradoxically spur gentrification and the displacement of existing lower-income residents, raising concerns for environmental justice.
