This dissertation, based on 26 months of ethnographic fieldwork in Kansas City, examines green urban development and urban agriculture projects from the perspective of residents in an African American majority neighborhood. It argues that dominant narratives of urban sustainability and agriculture, shaped by upper-middle-class white voices, support green development projects that marginalize and displace people of color and the poor. The study documents the lived consequences of these narratives and highlights resistance efforts by minority-led agricultural projects and neighborhood councils.

This study investigated the potential overlap between feral cat territories and human-frequented areas in the Richmond metropolitan area, Central Virginia, using GIS. From July to November 2016, 275 feral cats were trapped for TNR clinics. Findings showed that 8.0% of feral cats had the potential to range onto public elementary or preschool property, and 81.5% of those trapped in Richmond City could roam into public parks and community gardens, indicating a risk of zoonotic disease transmission.

The "Healthy Living Ambassador" school garden program in low-income communities integrated resources from schools, community programs, and the University of California Cooperative Extension. This program utilized culturally competent teenagers as teachers to educate elementary school youth on healthy living. The successes and challenges of the program development were discussed, revealing that public schools often lack the resources and support to establish sustainable garden-based programming.

This study analyzed the views of thirteen teachers in a public school in northeastern Brazil regarding the importance and use of a medicinal garden planted in 2014. Interviews revealed a lack of interest among teachers in using the school garden, despite most recognizing its importance as a didactic resource. The findings suggest that intervention projects in schools require teachers to be prepared for their use, highlighting the need for a teacher training plan.

A paper examining Philadelphia's 2008 prioritisation of healthy food access as part of sustainable development, in a city where almost 25% of the population is considered food insecure, prompting government agencies, NGOs, and community leaders to try to increase food access through expanded food production and land access. The paper argues that urban agriculture, gradually incorporated into sustainability narratives over the preceding decade, both provides advocates a platform to inform policymaking and risks stripping away the political and activist origins of the struggle for access to food, land, and green space, contending that this depoliticisation through incorporation into sustainability planning may serve to increase existing inequities in the city. Examining measures enacted under the Philadelphia Greenworks Sustainability Plan at the policymaking level, the paper's preliminary findings suggest a disconnect between urban agriculture advocacy and policymaking, and it states that further work is needed to understand the impacts of formalising urban agriculture in Philadelphia.

K. Michelle Glowa, Monika Egerer, Vicki Jones · Agroecology and Sustainable Food Systems · United States

This case study of the Beach Flats Community Garden in the United States theorizes an "agroecologies of displacement," arguing that farmers are increasingly uprooted through involuntary displacement and that this displacement and dispossession actively reshape agricultural practices in farming communities. The authors argue that food movements, and transformative agroecology in particular, cannot be understood without a historical analysis of displacement and dispossession under capitalist land systems — framing land loss and forced relocation, not secure access, as a structuring condition of the garden's agroecology.

David Ceaser · Agritecture · United States

In this December 7, 2018 article for Agritecture, horticultural consultant David Ceaser reports on the challenges facing agrihood development, using The Cannery in Davis, California (500+ homes, 150 acres, with a 7.4-acre organic farm) as a case study. He notes that residents held unrealistic expectations about how the farm would be run and their role in it, and that poorer-than-expected soil quality required amending with organic matter, delaying farm development. Farm Director Sri Sethuratnam described the aging farmer population and food-production challenges as "a national security issue."

This study conducted focus groups with 28 adults in three affordable housing communities in Washington, D.C., USA, to understand low-income adults' attitudes towards participating in farmers' markets, community-supported agriculture (CSA), and nutrition education programming. The results revealed that adults living in urban, affordable housing communities desire access to healthy foods but are limited by cost. Programs could have a higher likelihood of success if they accept benefits like SNAP (Supplemental Nutrition Assistance Program), are heavily marketed, and incorporate culturally relevant nutrition education components.

Community Supported Agriculture (CSA) growers in the United States may experience legal concerns and liabilities. This fact sheet aims to guide growers through steps to minimize these liabilities and manage possible risks associated with CSA operations. The presence of such concerns highlights a governance challenge for CSA growers.

Michelle Glowa · · United States (San Francisco)

In the San Francisco region, highly competitive land markets increasingly force landowners to use properties for purposes other than gardening, despite the popularity of urban agriculture. This situation compels gardeners to develop strategies to gain and maintain land access, linking gardening to broader land politics and urban design. The chapter explores how gardeners influence space production and property institutions.

Jennifer Wilhelm · University of New Hampshire Scholars Repository (University of New Hampshire at Manchester) · United States (New Hampshire)

This dissertation addresses agricultural extensification from several angles. Chapter 1's literature review showed an increase in research on urban and peri-urban agriculture (UPA) and ecosystem services, but highlighted a need for quantifying ecosystem services and functions to clarify ecological tradeoffs. Subsequent chapters focused on a mixed-methods study in New Hampshire, surveying approximately 600 residents (494 general population, 103 food system stakeholders) on their perception of forestland conversion to agriculture.

The "Eating good and moving like we should (EGMLWS)" school-based intervention aimed to prevent and reduce childhood obesity among primarily African American third-grade students in 7 Mississippi Delta schools. The program included curricula, school gardens, and school menu consultation. Pre- and post-intervention BMI z-scores and Fitnessgram parameters (PACER and back-saver sit-and-reach) were compared. Mean BMI z-scores significantly lowered in 2 schools, did not change in 4 schools, and increased in 2 schools. PACER scores increased in 5 of 7 schools, and sit-and-reach scores increased in 5 and 6 schools respectively.

· Policy Press eBooks · United States (Detroit)

Dan Carmody, President of Detroit's Eastern Market Corporation, discussed the market's history and its importance for food access in Detroit. He addressed the role of urban agriculture and the new wave of gentrification, which has the potential to significantly impact the Market.

Monika Egerer, Alessandro Ossola, Brenda B. Lin · BioScience · United States (California central coast)

This study conceptualizes community garden soils within the novel ecosystem framework, arguing that gardeners cultivate novel agroecosystems from their garden beds' soil. On the California central coast, community garden soils may not be influenced by land-use legacies associated with geographic location. Instead, intensive soil reworking by gardeners can wash out legacy signals and decadal chronological trends, leading to soil homogenization that reduces biophysical ties to the underlying earth.

Jennifer Jettner · VCU Scholars Compass (Virginia Commonwealth University) · United States

A mixed-methods approach examined race, racial diversity, and social capital in community gardens located in Southern urban food deserts in the United States. Results indicated that while gardeners were racially diverse across the sample, most community gardens were racially segregated, and the majority of gardeners appeared middle-class. Community gardens showed limited potential to advance social justice and indirectly enhanced community food security, primarily through the efforts of people of color, rather than directly benefiting food-insecure gardeners.

Jonathan Lowell, Sara Law · CABI eBooks · United States (Texas), Cuba

A comparative study of urban agriculture projects in Austin, Texas, and Havana, Cuba, revealed that sustainability discourses primarily focus on food production methods, with little attention paid to persistent food insecurity issues that urban agriculture has yet to address, or to the cultural politics of food, where race, class, and gender shape access to food choices. While agricultural practices and their perceived value were similar in both cities, the study found comparable outcomes in how food exposed spatial and social divisions.

Denes Dantas Vieira, Reimilde Gomes da Silva Amorim · EXTRAMUROS - Revista de Extensão da Univasf · Brazil (Juazeiro)

This study aimed to investigate the dilemmas of the social trajectory of the Povo Unido community garden in Juazeiro/BA, Brazil, located on the banks of the São Francisco River. This garden is known for its organic vegetable production and as one of the first groups focused on overcoming poverty and combating hunger in Brazil's semi-arid northeast. The research contributes to reflection based on social organization and organic food production.

Rebecca Gresh · Illinois Digital Environment for Access to Learning and Scholarship (University of Illinois at Urbana-Champaign) · United States (California)

This qualitative study investigated two alternative food projects in San Diego, California, to reveal how food justice is envisioned and practiced. "Project New Village (PNV)" in a low-income area resists institutional racism and class inequality through a community garden and farmers market. In contrast, the affluent "San Diego Roots Sustainable Food Project (SDRS)" resists suburban sprawl and environmental destruction through sustainable food production. PNV faces obstacles like law enforcement patrols interrupting community rebuilding, indicating that alternative food movements may reproduce structures of oppression.

An online survey of 37 educators (36% response rate) in South Carolina, who completed a school gardening training course between 2012-2015, assessed a pilot farm-to-school initiative. The study found that most educators were unaware their garden was part of the initiative, and gardens were not integrated with school-wide programs, particularly cafeteria meals. However, most educators maintained their gardens for over a year and used them for academic instruction.

Pascale Joassart‐Marcelli, Fernando J. Bosco · · United States (San Diego)

The alternative food movement (farmers' markets, community gardens) in San Diego, United States, was investigated in relation to gentrification. Uneven urban food landscapes were shown to be intimately connected to gentrification processes, shaped by race, class, political decisions, and capital flows. Farmers' markets and community gardens are primarily located in affluent and gentrifying areas, providing evidence of a growing appropriation of alternative food spaces by urban developers and cultural elites.

In Oklahoma, tribes have initiated numerous food projects over the past three decades aimed at achieving food sovereignty. However, Oklahoma's complex history, environmental issues, and current politics present challenges such as uneven food quality, poor indigenous health, intratribal factionalism, racism, and a stark dichotomy of affluence and extreme poverty. These factors complicate the creation of self-sufficient food systems and the reconnection of tribal members with traditional foodways.

Dorothy Menefee, Ganga M. Hettiarachchi · · United States

Soil contamination with potentially toxic trace elements and anthropogenic organic pollutants is a widespread problem in urban areas worldwide. While urban agriculture increases food security, potential risks exist without knowledge of urban soil contamination. Lead (Pb) contamination is a widespread and common urban soil issue associated with human health risks, with almost half of US EPA Superfund sites having Pb contamination. Cadmium (Cd) is also a widespread urban soil pollutant, largely from industrial activities like plastic manufacturing, battery disposal, and metal ore processing. The bioavailability of soil Pb to humans is unusually low and generally tied to Pb speciation.

Lindsay K. Campbell · Cornell University Press eBooks · United States (New York City)

This chapter analyzes why urban forestry was prioritized in New York City's PlaNYC mayoral initiative while urban agriculture was overlooked. It examines the networks, public-private partnerships, elite ties, and bureaucratic structures involved in PlaNYC, revealing that certain voices were heard while others were ignored in the sustainability planning process. The analysis highlights issues of governance and equity in urban nature planning.

In New York City, chapter six revealed how civic and public actors working outside PlaNYC iteratively embedded urban agriculture and food policy into municipal planning efforts. Within the void created by city hall’s lack of engagement, other figures in the municipal government seized the opportunity to advance food policy agendas for New York City. The 2011 update to PlaNYC included a brief crosscutting section on food, although it lacked capital funding to fuel the achievement of its stated goals, and was seen by advocates as a symbolic and political achievement.
