This study used multiple land use scenarios to assess different spaces in Montréal, including residential gardens, industrial rooftops, and vacant land, that could be allocated to vegetable production. Results indicated that implementing hydroponics on industrial rooftops could easily satisfy Montréal's vegetable demand, though these operations are generally costly. Utilizing only vacant space also has the potential to meet the city's demand with lower operating costs.

This document compiles research reports written by students in the Environmental Resource Studies/Science (ERTS) 3160H class at Trent University in the winter of 2014. The students critically examined urban food forests around the world and made suggestions for designing a food forest in Peterborough. Urban food forests have the potential to provide the same services as current urban forests, but also produce food and perhaps increase biodiversity in the process.

A study used Geographic Information System analysis to measure land potential for urban agriculture in four sub-urban neighborhoods in Waterloo, Ontario, Canada. Findings show that 49-58% of the land measured has potential to support urban agriculture; in older post-war sub-urban neighborhoods this potential lies primarily in private yards, while newer sub-urban neighborhoods incorporating new urbanist ideals have smaller yards but more public green space, meaning challenges and opportunities for urban agriculture differ between older and newer sub-urban areas due to differences in neighborhood design.

Orange County, FL, with a population of 1.2 million, is rapidly urbanizing. In 1998, 20,000 acres of local vegetable production ceased due to concerns about phosphorus-laden water discharges into Lake Apopka, shifting the county from a net exporter to an importer of vegetables. The Urban Farming Extension Education Program aims to identify, demonstrate, and encourage the adoption of sustainable agricultural production methods usable in and around urban centers to leverage local markets.

Frank Lloyd Wright's Broadacre City proposed a decentralized, agrarian landscape, which was reflected in post-WWII American suburbanization. However, the agrarian ethos of Broadacre City is absent from both suburbia and its alternatives. The rising interest in urban agriculture is argued to represent a demand to reconnect with the land, suggesting that planners should incorporate agrarian design into urban growth models.

This study evaluated consumer perceptions of organic and locally grown produce at farmers' markets in North Carolina, focusing on the Piedmont Triad region. Using qualitative methods with focus groups from five locations, preliminary findings showed consumers distinguish local and organic foods only by labeling. Participants had limited knowledge of organic certification, and while most purchased more local foods, they were willing to pay up to 100% more for organic food.

This study identifies seven perceived barriers to urban and peri-urban agriculture in the greater Chicago metropolitan area through interviews with urban planners and farmers. All seven barriers involve unclear or agriculture-unfriendly regulations. Results suggest that urban and peri-urban farmers are commonly forced to operate within a legal limbo or petition for exceptions to current regulations.

This study examined the practices, outcomes, and motivations of guerrilla gardeners in California's East Bay through nine interviews. Projects occurred on different scales involving individuals, neighborhoods, community-based organizations, and 'Occupy the Farm,' demonstrating outcomes such as youth empowerment, community building, and civic engagement. Guerrilla gardening was shown to facilitate inclusive community organization, expand social capital, and build local resiliency and assets.

This case study analyzed water management during the 2007-2009 drought in Athens, Georgia, examining how urban agriculture sector members recognized multi-scalar water management and used these interactions for political benefit. The study found that interactions between state, regional, and local drought management, drought perceptions, and interpretations of power to manage water during the drought led to the approval of Georgia House Bill 1281, which changed how water is managed during drought. This paper argues that it is necessary to consider the perception of drought and drought management, as well as the drought itself, because they influence how stakeholders participate in political processes and change how water is used during drought.

In São José dos Campos, São Paulo, Brazil, residents of the Altos de Santana neighborhood maintain traditional peasant characteristics by cultivating urban gardens within a Permanent Protection Area of the Paraíba do Sul River. However, the current municipal administration plans to implement an urban park in this area, which will remove the gardens cultivated by these resident farmers. This intervention is expected to alter proposals for improving the quality of life for nearby residents concerning urban agriculture, potentially generating conflicts between stakeholders regarding land use.

Charles E. Hess · HortScience · United States

Reflecting on horticultural science over the past 60 years, it is evident that it is in a period of great opportunity. Recognition of the role of fruits and vegetables in a healthful diet has led to food for health initiatives that encourage diets rich in horticultural crops. The 'locavore movement' fosters the popularity of purchasing locally, spurring increased interest in farmers' markets and urban gardening. Internationally, the idea of peri-urban gardening recognizes the value of horticultural crops in improving nutrition and income on relatively small areas of land in developing nations.

Kassey Steele · ˜The œAgricultural education magazine · United States

This paper discusses the increasing relevance of urban agriculture in the United States, where the urban population was almost 80% in 2010 and continues to grow. It argues that as urban dwellers increasingly influence food consumption decisions, understanding agriculture becomes crucial. The paper suggests that university agricultural education programs should prepare pre-service teachers to address the needs of a predominantly urban population, making urban agriculture a less contradictory concept.

Amanda Jessie Weaver · Digital Commons - DU (University of Denver) · United States (Colorado)

This project combined U.S. Agricultural Census data with a survey of local producers in Colorado's Front Range Urban Corridor to examine the competition between urban development and food production. The study found that urban development is increasingly encroaching on rich agricultural lands, which are also desirable for housing. Consequently, Colorado faces increasing competition for land, potentially driving local food prices up and displacing producers to peripheral areas or out of food production entirely.

This research aimed to enhance Waikīkī's image with sustainable planning and design, focusing on visitors' perceptions. While visitors' images of Waikīkī were primarily positive, the region faces environmental problems including inadequate recycling, transportation, and agriculture/aquaculture issues. The project proposes a new sustainable solution incorporating urban agriculture with an international event, Expo Hawai‘i 2020, to address these environmental challenges.

California State Legislature · California Legislative Information · United States

California's AB-551 (enacted 2013-2014 session) allows local governments to establish Urban Agriculture Incentive Zones, letting landowners enter contracts of at least five years to have land used for agriculture assessed at the lower value based on the state's average irrigated farmland value, rather than market value. Eligible parcels must be between 0.10 and 3 acres, dwellings are prohibited on the property while under contract, and new contracts originally had to begin by January 1, 2019.

The British Columbia Farmland Preservation Program, established by the Land Commission Act on April 18, 1973, aims to preserve the province's valuable farmland. This program has sustained economic and social benefits from agriculture, preserved community character, and maintained natural capital. The Agricultural Land Reserve (ALR) has also acted as an urban growth boundary, contributing to compact urban development and addressing land use conflicts.

Bruntfield, Jaclyn Rose · Scholars Archive - University at Albany (University at Albany, State University of New York) · United States (Columbia County, NY)

This abstract discusses the increased public scrutiny of food origins in the U.S. and the growing demand for alternatives to the mainstream food system, as evidenced by more farmers markets, organic products, and Community Supported Agriculture programs. It notes that post-WWII industrialization of food production, while providing inexpensive food, has potentially compromised people's relationships with food. Currently, only one percent of Americans identify farming as their primary occupation.

Siqing Chen · APCBEE Procedia · United States

This paper uses a housing development project in the United States to exemplify how civic agriculture can be integrated into urban development through forms like Community Supported Agriculture (CSA), kitchen gardens, and farmer's markets. This integration creates a local food web, enhancing civic engagement and welfare among residents, maintaining landscape authenticity, strengthening ecosystem services, reducing carbon footprint, and promoting long-term sustainability. Civic agriculture represents a transition in agricultural practice from large-scale commodity enterprises to small-scale, self-sustaining civic activities.

This study evaluated consumers' willingness to pay for organic certification programs using price and attribute data from 188 CSA farms in Ohio and Pennsylvania. A semi-log hedonic analysis revealed a willingness to pay approximately 9% more for organic branding compared to natural, translating to an additional $48 per summer season share. However, no premium was found for competing certification programs.

This article investigates urban agriculture practices in Itajaí/SC, Brazil, to identify their potentials and obstacles for territorial development. Using participant observation and semi-structured interviews, the study concludes that urban agriculture is an expanding phenomenon closely linked to rural exodus. It also serves as a space for the conservation of traditional knowledge.

W. H. Butler · Journal of Agriculture Food Systems and Community Development · United States

The reintroduction of livestock into urban areas in the United States creates tensions regarding public health and the urban-rural divide. This paper analyzes municipal codes to identify how communities regulate urban livestock through prohibitions of certain animals, zoning, site-level restrictions, and management requirements. The analysis demonstrates that while no two municipalities approach the urban livestock question identically, each seeks to place limits on raising livestock in urban areas using a combination of regulatory land use tools.
