In this interview chapter, Grace Lee Boggs discusses revolution, evolution, and change in Detroit, reflecting on her life's work. Boggs states that revolutions stem from communities claiming spaces to realize their desired world, rather than from seizing power. She views urban agriculture and other grassroots movements as acts of revolution that help "grow our souls," highlighting Detroit's pioneering role in this new approach.

This study conducted a qualitative, inductive survey of community orchard organizations in the U.S. (42.64% response rate) to establish a baseline understanding. Participants were identified via internet presence, meaning little is known about orchards without an online presence. Findings showed that community orchards are primarily established on public land, with primary motivations including environmental concern, education, and a sense of community. Organizers reported that fruit and nuts produced feed residents in the immediate surrounding area.

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.

This study collected 32,237 wild bee specimens (200 species, 6 families) from 46 sites in Montreal and Quebec City in 2012 and 2013, across cemeteries, community gardens, and urban parks. It demonstrated that cities are home to diverse communities of wild bees, which in turn affect bee community structure and dynamics. Community gardens specifically harbored high levels of functional trait diversity, suggesting a substantial contribution to urban pollination services.

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.

This study assessed the potential of urban land to grow "climate smart food," a term proposed to examine the environmental impact of urban food production. Using the Bowness neighbourhood in Calgary, Alberta, as a case study, a geospatial constraint mapping process analyzed suitable private land for conversion from lawns to gardens. In 2016, six urban farms in Calgary produced approximately 8,200 pounds of food from private gardens, while 42% of Bowness's private turf grass land produced only about 800 pounds, quantifying underutilized urban land for food production.

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.

This qualitative fieldwork in a large, urban school district in Northern California explored school food reform efforts addressing childhood obesity. Reforms transpired through three processes: sustained involvement of parent-activists, leadership by the school food service director in championing farm-to-school efforts and facilitating partnerships, and widespread community support for funding and implementation. These findings indicate how local social change transformed public school food programs to benefit youth health.

This ethnographic study, conducted from August 2013 to August 2014, examined Orchard Hill Farm, an organic, draft-horse powered Community Supported Agriculture (CSA) farm in Sparta, Ontario, Canada. It found that the farm's management approach resulted in a financially viable small-scale farm. The study highlighted that CSA members experience a "re-enchantment" through closeness to food and the farm, while farmers and apprentices demonstrate a commitment to sustainable practices.

Sydney Giacalone · Journal for Undergraduate Ethnography · United States (Boston)

This ethnographic study, conducted in Boston and Somerville in the summer of 2016, investigated how urban chicken keeping might transform keepers’ thinking about food systems and animal relationships. The research revealed the unexpected discovery of lead contamination in urban chicken flocks in the Boston area, which unsettled the imagined simplicity of urban agriculture and exposed a "metabolic rift." This finding prompted keepers to engage more deeply with the history of the soil and opened new ways of thinking about collective metabolism, multispecies living, and food politics.

This study examined 25 urban community gardens in California to investigate relationships between soil properties and neighborhood socio-demographics, focusing on (1) how groundcover management affects soil properties, and (2) how socio-demographics, particularly social advantage, affect groundcover management and soil properties. Mulch groundcover was found to improve soil fertility and water holding capacity in gardens, and socio-demographic factors appeared to affect residents' access to mulch: neighborhoods with higher mobility (e.g., greater vehicle availability) but poorer public/environmental health indicators (e.g., poorer health care access) had higher soil organic matter, nutrient content, and water holding capacity. However, indicators of high-functioning soils were also found in the absence of mulch, suggesting that other factors such as social networks and organizational support may also be important for ecosystem services in urban agricultural systems.

A controlled pilot study offered 95 first-time shareholders drawn from a university wellness program a $200 voucher to join a Community Supported Agriculture (CSA) program, surveying food lifestyle behaviors before and after participation and comparing changes against an 82-person control group using econometric analysis. Changes were found in four categories — fresh versus processed food consumption, food prepared at home versus away, food purchasing behavior and interest in nutrition, and self-reported health outcomes — and these changes were more strongly realized among shareholders who reported lower-than-average health prior to the CSA.

Lewis C. Gray, Lucy Diekmann, Susan J. Algert · CABI eBooks · United States

This book chapter examines the renaissance of urban agriculture in North America since the 1960s creation of community gardens, asking whether it is producing enduring landscapes and socio-economic change or is transitory like past movements. After surveying broad research themes — civic engagement, community development, food justice and ecosystem services — the chapter examines barriers to and impacts of urban agriculture in Santa Clara County, Silicon Valley, where significant economic disparities are reflected in unequal access to different forms of urban agriculture.

This report examines a comprehensive community wellness initiative launched in 2014 in Meadville, Pennsylvania — a town classified as a food desert under USDA criteria, where 26.1% of residents lived in poverty and nearly 13% had poor nutritional status in 2014, and where an estimated 70% of adults regionally were overweight or obese with childhood obesity above 30%. The initiative established community gardens, piloted a fresh fruits and vegetables program in a local elementary school, and launched a mobile farmers market — piloted in summer 2016 in collaboration with the local bus company — targeting a low-income neighborhood to increase access to fresh produce and reduce obesity.
