This study assessed participants' lived experiences and place meanings in urban-agricultural fringe landscapes in the Chicago metropolitan area and Urbana, Illinois, using an autodriven photo elicitation method (APEC). Participants expressed place meanings that valued human history, tolerated human development, and indicated a need to heal the land. These findings informed two principles for park development: embodying public memories and allowing community-based restoration of ecological and cultural heritage.

This paper discusses SPIN-Farming as a tool to demonstrate the economic viability of urban agriculture, which was initially advocated in Philadelphia in 1998. While social and environmental benefits are clear, economic proof was needed to motivate policymakers. The author applied entrepreneurial experience to develop SPIN-Farming, aiming to revive the farming profession and enable a scalable, accessible farming concept across economic classes and geographical boundaries, fostering local food systems.

Christopher Davis · OhioLink ETD Center (Ohio Library and Information Network) · United States

A master's thesis addressing persistent socio-economic inequality and environmental destruction in the contemporary American city, particularly environmental injustice, decaying historic structures, poor health, weak community support systems and gentrification pressure in impoverished urban neighborhoods, proposes urban agriculture as a comprehensive, integrated solution spanning urban revitalization, environmentalism and historic preservation. The research culminates in a project adapting rooftops in impoverished urban neighborhoods into a network of public agricultural gardens intended to beautify and revitalize the area.

Randall Walsh · Journal of Urban Economics 61(2): 319-344 · United States

Uses a locational-equilibrium model that treats both privately held open space and land-conversion decisions as endogenous to evaluate the metropolitan-wide impact of open-space policy. Shows that once endogenous adjustment of private open space is allowed for, expanding public preserves can actually reduce the total quantity of open space across a metropolitan area. Also finds that different strategies for spending the same open-space budget have markedly different land-use and welfare consequences.

Urban Harvest / Centro Internacional de la Papa (CIP) · Urban Harvest, Centro Internacional de la Papa (CIP) · Peru

Urban Harvest, the global urban and peri-urban agriculture initiative coordinated by the International Potato Center (CIP), published in 2007 the proceedings and declaration of its Third Inter-institutional Meeting held in Lima on 25-26 August 2006. The report notes that Lima Metropolitana spans the lower basins of the Chillón, Rímac and Lurín rivers, with the Rímac's average flow of 29 m3/s far exceeding the Chillón (5 m3/s) and Lurín (0.41 m3/s), while bacterial contamination in all three rivers exceeds the vegetable-irrigation limit of 1,000 fecal coliforms per 100ml. In Villa María del Triunfo, a municipal urban agriculture program began in 2001, and by 2006 the municipality had identified 1,926 people engaged in productive urban agriculture.

A 2005 study in Campinas, Brazil, analyzed the city's Community Garden Program (PHC) to support the formulation of new urban and peri-urban agriculture policies. Analysis of PHC management revealed an almost total disengagement between the program and sectoral policies such as education, health, and social action. However, individual actions were found to be important for project implementation and success, and the projects were significant in the lives of beneficiaries.

This study analyzed the spatial and temporal dynamics of land occupation in urban areas of Santa Maria, RS, Brazil, and determined land use conflicts using data from 1975 to 2002. Urban land use increased from 9% in 1975 to 33% in 2002. Land use conflicts increased from 19% in 1975 to 37% in 1995, then decreased to 33% in 2002. The main problems of improper land use are related to the fragility of geological material and soil resources for use in construction and urban agriculture.

Lisa Patterson · Scholarly Commons (University of Pennsylvania) · United States

This comparative case study uses ethnographic fieldwork to analyze the Urban Nutrition Initiative and a community-supported agricultural garden in the United States. It describes the organizational foundations of development agencies within a public policy framework and discusses power relationships between advocates and clientele in social service networks. The study demonstrates that power transitions in development schemes indicate social movements, which are defined as markers of successful strategies through a community empowerment model.

Fabrício de Araújo Pedron, Ricardo Simão Diniz Dalmolin, Antônio Carlos de Azevedo, Everton Luís Poelking, Pablo Miguel · Ciência Rural · Brazil (Santa Maria)

This study conducted an environmental diagnosis in urban areas of Santa Maria, Brazil, using the Urban Land Use Potential Assessment System (SAPUT) to identify land use conflicts. Remote sensing and geoprocessing techniques were employed. The identified problems of improper land use are related to the fragility of geological material and soil resources, with up to 33% of the area being used beyond its potential due to inadequate use for construction and urban agriculture.

R. Robles · Revista Agraria · Mexico (Mexico City)

This paper provides an overview of urban agriculture in Mexico City and its conurban area, contrasting production models in developing and developed countries. It reviews the main urban, suburban, and peri-urban production systems and discusses public policies for promoting urban agriculture. The study concludes that no specific policy has been designed to promote urban agriculture in Mexico.

The UBC Food Systems Project evaluated the effects of campus development on creating a sustainable food system at the University of British Columbia (UBC). Researchers identified barriers and opportunities in UBC's Official Community Plan (OCP) and Comprehensive Community Plan (CCP), then proposed "The Edible Campus" urban agricultural strategy. This strategy included six actions like demonstration gardens and food production on buildings, with recommendations for future viability studies.

M.R. Gorham, Tina M. Waliczek · HortScience · United States (Houston)

This study aimed to determine if a relationship existed between reported property crimes and the presence of inner city community gardens in Houston, Texas. Property crime data from 1995 through 2004 were obtained from the Houston Police Department, and crime rates within a 1/8-mile radius surrounding community gardens were compared to the property crime rate for the entire police beat. The abstract does not state the study's results.

Brian Noy · University of Minnesota Digital Conservancy (University of Minnesota) · United States

A research project examined community gardens in the Twin Cities, Minnesota, USA, against a backdrop of rising development pressure and disappearing vacant space, looking at public land use policies and how cooperation between public agencies and community organizations affects garden creation and protection. Creating an inventory of public land use policies in St Paul and Ramsey County, including the city's water utility policy for community gardens, the project found that gardening is possible on most types of public land and that gardens have had generally successful relationships with most landowning agencies—but also found that a lack of this policy information has been a crucial barrier to garden implementation and has in some cases prevented development. District councils were found to both collaborate with city planners and act as community organizers, giving them, as nonprofits with a direct relationship to city government, access to funding and public lands not available to other organizations.

Samantha Langley-Turnbaugh, David E. Wilkinson, D. Rocque · Soil Survey Horizons · United States

This study characterized urban soils in a low-income neighborhood of Portland, Maine, that was heavily industrialized in the late 1800s, examining seven pedons for particle size, cation exchange capacity (CEC), base saturation, exchangeable bases, pH, and trace elements (Pb, Cr, Cu, Co, Cd, Ni, Zn, Hg, Ti, Zr). The soils contained numerous artifacts and showed a high degree of horizontal and vertical spatial variability; several trace elements were present at elevated levels, with lead (Pb) the dominant metal in surface horizons (600 mg/kg), and many metals correlated with each other and with iron and aluminum, and some with clay content and pH, though the study concludes that mapping soil units by specific trace element ranges would be difficult given the extreme variability observed.

Lauren Baker · Geographical Review · Canada (Toronto)

Toronto's community gardens, numbering over 100, are sites of place-based politics linked to the community food-security movement. These gardens reflect the city's cultural landscape and serve as a strategy to regenerate the local food system and provide access to healthy, affordable food. Three case studies illustrate the complexities of "food citizenship" and the role gardeners play in transforming urban spaces.

Laura Lawson · Journal of Planning History · United States

This historical review of US community garden programs since the 1890s reveals an ambivalent relationship between community gardens and the planning profession. While praised for serving environmental, social, and individual objectives, community gardens are largely ignored in long-range planning due to being perceived as opportunistic and temporary. This highlights unresolved tensions between professional planning and civic concerns, and between comprehensive planning and local interventions.

CAST · · United States

This comprehensive report by a twelve-member task force examines the changing role of agriculture in urban settings within historical and contemporary American society. It outlines geographic, demographic, and economic changes in rural and metropolitan life, considering policy issues such as land preservation, alternative market opportunities, sprawl, taxation, and food security. The report also presents research and educational challenges for higher education institutions.

Kenny Lynch · · United States

A 1992 survey by Bryant and Johnston in the US examined farming in the 'city's countryside'. The survey found that key concerns among farmers included changes in the local community, excessive traffic, issues of trespassing and vandalism, and complaints from non-farm neighbors. These findings indicate challenges in governance and community relations for peri-urban farmers.

Community gardens enhance nutrition, physical activity, and social capital, promoting public health and quality of life. The California Healthy Cities and Communities (CHCC) program funded successful community gardens in several cities, which incorporated local leadership, volunteers, and skill-building. These initiatives led to policies for land and water use, improved produce access, and strengthened community building skills.

Christopher M. Smith, Hilda E. Kurtz · Geographical Review · United States (New York City)

New York City community gardens have faced political contestation for thirty years, notably in 1999 when 114 gardens were slated for public auction and redevelopment. This article examines the controversy as a politics of scale, where garden advocates expanded the dispute beyond individual gardens and the city. The analysis highlights the significance of scale politics for grassroots organizations within a market-centric, neoliberal economic framework.

Troy D. Glover · Journal of Leisure Research · United States

This narrative inquiry explored how 14 participants in the Queen Anne Memorial Garden, a community garden built to combat urban decline, collectively reconfigured events into a “success story.” The aggregated community narrative illustrates how a collective leisure pursuit can be a grassroots effort to address urban decline and reshape collective identity.

This paper describes the design and data collection for an on-site evaluation to quantify the benefits of greenroof systems, focusing on six greenroof systems in the Greater Toronto Area, Canada. The study's objective is to specifically quantify the multiple benefits greenroofs provide, such as improved stormwater management, air quality, increased energy efficiency, extended roof life cycle, and mitigation of the Urban Heat Island Effect. A long-term, real-time monitoring program is intended to help define the ecological and hydraulic benefits of these greenroofs.

This paper compared the successes and failures of two urban creek restoration programs in California: Temescal Creek (initiated nearly 30 years ago) and White Oak Creek (completed about four years ago). Based on the author's success criteria, the more recent White Oak Creek program achieved significant success, while the earlier Temescal Creek restoration did not reach generally acceptable success levels. This difference is attributed to changes in management and scientific practice over 30 years, including substantial changes in the legal basis for restoration, improved monitoring requirements, and the critical role of properly engineered low flow distribution structures.

Lynn A. Staeheli, Don Mitchell, Kristina Gibson · GeoJournal · USA (New York City)

Analyzes the Giuliani administration's 1998–1999 policy of transferring community gardens to housing development and auctioning 100+ gardens, exposing how a city 'greening then privatizing' policy reversed itself and treated public gardens as disposable exchange-value assets.
