A study in community gardens in San Jose, California, from Spring to Summer 2012, evaluated a method for quantifying crop yields and cost savings. Eighty-three community gardeners completed a background survey, and a representative subset of 10 gardeners measured produce output from their plots over a four-month growing season. Results indicated that community gardens produced 0.75 lbs of vegetables per square foot, exceeding conventional agricultural practices at 0.60 lbs/sq ft. Gardens averaged 2.55 lbs per plant and resulted in $435 in cost savings per plot for the season.

A survey of Wisconsin-certified organic vegetable farmers investigated the relationships between farm characteristics, marketing strategies, and farmers' perceptions of profitability and quality of life. The data indicated that farmers selling into farmers' markets and through community-supported agriculture (CSA) were more likely to be dissatisfied with their profitability. Conversely, farmers selling into wholesale markets and restaurants/institutions were significantly more likely to be dissatisfied with their quality of life.

Richard C. Sadler, Godwin Arku, Jason Gilliland · Local Environment · United States (Flint)

This study examined local food networks (LFNs) and a food policy council (FPC) in Flint, Michigan, a post-industrial city facing food access issues. Participant observation with stakeholders revealed support for community gardens, farmers' markets, and urban agriculture. Based on the synthesis of stakeholder opinions, policy recommendations were developed to aid in the continued planning of the LFN.

This study assessed the impact of selected socioeconomic factors on residents' perceptions of community garden benefits in Macon County, Alabama. Data from a convenience sample of 217 participants, collected via questionnaire, showed that at least 73% agreed with nutritional, health, and community benefits. Age, education, and annual household income had statistically significant effects on these perceptions.

Pascale Joassart‐Marcelli, Fernando J. Bosco · Métropoles · United States (California)

This article explores the growth of local food practices in urban southern California, focusing on farmers' markets. While alternative food initiatives like farmers' markets are often seen as resistance to capitalist pressures, this research provides evidence that they have become increasingly popular among affluent and white urban residents. This finding challenges the claim that local food fosters democracy and justice, indicating that these initiatives can reproduce neoliberal urban agendas and reshape cities along lines of race and class.

Laura Oliven Silberfarb, Sonja Savre, Gayle Geber · Preventing Chronic Disease · United States (Hennepin County)

Hennepin County assessed the extent to which 41 cities were engaged in making policy, systems, and environmental (PSE) changes to increase residents' access to healthful food. Results revealed that some cities, particularly those with higher resident demand for healthful food, are making nationally recommended PSE changes, such as sponsoring farmers markets. However, cities moved more slowly to make changes in areas with perceived negative cost consequences or lesser public demand, such as parks and recreation vending.

State and local policies promoting urban agriculture contribute to revitalizing postindustrial American cities. Urban food systems encompass aspects of producing, processing, marketing, distributing, and consuming food, providing a multiplicity of benefits and services for local residents. These benefits include improved access to outdoor recreation, economic vitality, health and wellbeing, landscape beautification, and environmental restoration.

Nevin Cohen, Kristin Reynolds · Journal of Planning Education and Research · United States (New York City)

This article examines urban agriculture (UA) policy-making processes in New York City, focusing on aspects of UA not fully addressed by existing policies, plans, and research strategies. Interviews with UA stakeholders and an analysis of the city’s UA policy-making processes show that resource needs and race- and class-based disparities within the UA system persist.

Benjamin Drury, Renee Laliberte, Jared Watson, Connor Wilgress · Digital WPI · United States (Worcester)

The city of Worcester, MA, faces health issues due to economic instability and low access to affordable healthy food. While urban farming has the potential to address these problems, the city lacks an effective policy.

Cristina Connolly, H. Allen Klaiber · American Journal of Agricultural Economics · United States

This study used a hedonic model with firm-level prices and CSA characteristics from 453 CSA farms in Michigan, New York, Ohio, and Pennsylvania during the summer 2012 growing season to value CSA attributes. Results showed a price premium of approximately 7% for USDA organic certification, though this varied by state, but no premium for competing certified naturally grown programs. CSA farms exhibited little market power and appeared to act competitively.

Matt Murray · Journal of Political Ecology · United States (New York City)

Efrat Eizenberg's book "From the Ground Up" explores New York City's community gardens as spaces that resist the commodification of land. The book details the history of these gardens, including their emergence during the 1970s economic crisis when primarily Black and Hispanic residents transformed vacant land into communal green spaces. As the real estate market recovered in the 1980s, land values increased, and many gardens were threatened by gentrification pressures. Eizenberg analyzes these transformations at individual, collective, and institutional levels, highlighting how gardeners create common spaces, solidify interpersonal ties, and organize to defend their gardens.

Alexandra Jeanne Hiniker · Digital Commons - Hamline (Hamline University) · United States

This study surveyed Community Supported Agriculture (CSA) farms in Minnesota, asking farm owners and operators about demographics, farm specifics, and marketing practices. Results indicate that Minnesota's CSA community is robust and diverse in its offerings. It was found that face-to-face communication is preferred above all else to support farm activities.

Rafael Ângelo Fortunato, Elza Neffa · Revista Turismo em Análise · Brazil

This article reflects on the potential of solidarity tourism for local development, analyzing the "Horta Comunitária do Morro da Coroa" community garden in Brazil. Based on a literature review, phenomenology, and one year of participant observation, the study identified the potential of the "6Vs" of solidarity tourism as pillars for a new concept. It also found that network formation, as proposed, is an important instrument for political action aimed at strengthening local development initiatives.

Nicole M Reese · USF Scholarship Repository (University of San Francisco) · United States (California)

This study assessed the feasibility of rooftop farming in the Small Business Mix Zone of West Oakland, California. The area has more than one million square feet of untapped rooftop space, and selling produce grown there at local farmers markets, produce stands, grocery stores, businesses, and restaurants could generate up to $4 million in revenue. Rooftop production would help the City of Oakland meet its goal of 30% locally sourced food and supply fresh fruits and vegetables to West Oakland, a food desert currently lacking access to them.

A study identifies and classifies localized urban agriculture trends taking place in Vancouver, Canada, by efficiency, viability and long-term potential over a 2040 time frame, based on literature reviews of theory, ideology, concepts and local trends. It finds that urban agriculture within the city of Vancouver is struggling to find a long-term foothold due to issues including overuse/misuse of technology, underfunding or poor budgeting, community attitudes, lack of knowledge about agriculture and food safety, lack of long-term sustained relevance, bureaucratic struggles, and lack of usable space in a growing city. It recommends focusing on strong community involvement through social media and programs, educational programs, movable or adaptable planting spaces, and alternative food assets such as farmers' markets.

A report and presentation on Rosemount urban agriculture's food producers and food production was completed by students enrolled in SUST 4004: Sustainable Communities, taught by Samantha Grover and Amir Nadav at the University of Minnesota in fall 2014; no further details of content or findings are given.

Paul Joseph Draus, Juliette Roddy, Anthony McDuffie · Urban Studies · United States (Detroit)

Based on 20 qualitative interviews with people working or living in a heavily depopulated section of Detroit slated for an urban agriculture project, this paper examines residents' views of the project, which proposes using vacant land and marginalized residents to produce marketable products. Most respondents had little hope for neighborhood improvement and few expectations that urban agriculture would change daily life, viewing some efforts with suspicion. Drawing on concepts of advanced marginality and neighborhood effects, the authors argue idealistic urban agriculture efforts must do more to engage residents and address legacies of displacement.

Ross K. Wagstaff, Sam E. Wortman · Renewable Agriculture and Food Systems · United States (Chicago)

This study measures atmospheric pollutants, microclimatic factors, and the physiological response and yield of vegetable crops across an urban-to-rural transect of six sites in the greater Chicago region, aiming to determine their relative influence on urban food production. Preliminary 2013 data suggest substantial variability in environmental factors and crop yield across the transect, and the work aims to establish practical crop and cultivar recommendations for urban and peri-urban farmers in the North Central US.

In Kwon Park, Patricia Ciorici · International Journal of Urban Sciences · United States (Philadelphia)

This study in Philadelphia, United States, identified determinants of vacant lot conversion into community gardens using a logit model. Data on lot attributes were collected from the Philadelphia Neighbourhood Information System and a city-wide survey. The results indicate that neighborhood characteristics like poverty level, educational attainment, zoning, and owner occupancy, along with parcel characteristics such as ownership and topography, significantly impact the conversion.

Ryan E. Galt · Economic Geography · United States (California)

A study of 54 Community-Supported Agriculture (CSA) farms in California's Central Valley used qualitative and quantitative data to explain farmers' earnings. An ordinary least squares regression analysis revealed that farmers' age, number of employees, and CSA type strongly influence earnings. The study found that the moral economy of CSA often results in self-exploitation due to farmers' strong sense of obligation to members, despite allowing for economic rents.
