In New York City, community gardens were established by resident groups in the 1970s, contributing to recreation, food security, and sustainable urban development. Their number has fluctuated over the past 30 years, with approximately 600 gardens existing today, over 300 of which are on public land. Recently, in response to climate change and economic crisis, elements like beehives and rainwater harvesting have been legalized and used to maximize food production and conserve water. This chapter will use qualitative data analysis, secondary literature discussion, and participant observation to evaluate the employment and function of these garden components and how the city's community gardens contribute to a sustainable city.

Micro-agriculture refers to small-scale agriculture, in contrast to intensive agriculture and monoculture. It is a collection of 'small scale' agricultural practices, including horticulture (such as urban vegetable gardens), fruit-growing, or flower-growing. Micro-agriculture is a landscape defined by garden plots and materials, forming a unified yet diversified whole that differs from traditional agricultural landscapes in its reduced scale, biological richness, material variety, and heterogeneous landscape.

This paper, focusing on Toronto, identifies subtle impediments to scaling up urban agriculture beyond self-provisioning, despite land not being an insurmountable barrier. These include taxation systems assuming agriculture is a strictly rural activity, inadequate knowledge sharing among urban producers, limited access to soil, water, and seeds, and a lack of incentives for landowners. Achieving 10% of the city's commercial fresh vegetable demand requires significant policy and program initiatives in five key areas, including governance, coordination, and financing.

Urban food security is a critical issue in Dakar's housing projects, where limited access to fresh produce exacerbates poverty and malnutrition. This action research study conducted qualitative interviews with 50 participants from four housing projects in Dakar to understand their gardening practices and perceptions of food security. Residents reported a significant 34% increase in fresh produce consumption due to community gardens, leading to improved health outcomes. Community gardens have successfully contributed to urban food security by fostering local nutrition and improving residents' well-being.

In Tunja, Colombia, an intervention strategy to increase vegetable availability in a community was implemented through a qualitative study applying five principles of community-based research. The strategy included educational and urban agriculture components, involving seven participatory educational sessions and the implementation of eight home gardens and one community garden. The intervention increased vegetable availability, empowered the community, created social networks, and highlighted the role of nursing professionals in leading community actions for healthy lifestyles. The consumption of five portions of fruit/vegetables daily was insufficient in Tunja's 15-44 age group.

This study examines urban farming in Detroit, a city experiencing rapid decline with a population under a million, limited access to fresh food stores, and extensive vacant land. While arguing for modern urban farming as a foundation for sustainable practices and positive development, it notes that some political and business analysts question its ability to make a significant impact on the city’s future.

Martijn Koster, Pieter A. de Vries · Focaal · Brazil (Recife)

This article examined slum dwellers' politics in Recife, Brazil, as a realm of possibility where care and recognition are central. A community leader's urban agriculture project, which from an outsider's perspective might be considered non-viable, provided slum dwellers with possibilities to strive for community solidarity and personal recognition. The article concludes that slum politics is about claiming the right to be counted and recognized, and about the care for the other.

This study tested social capital as a measurable indicator for community garden planning in Akron, Ohio, by identifying vacant parcels in areas with fewer civic engagement hubs. Using an adapted methodology that introduced spatial components to social capital at the neighborhood scale, it identified sites with a greater need for social capital. A limitation was that the principal hubs of civic engagement identified were churches, suggesting further fieldwork is needed to identify site-specific social hubs.

This study analyzed the case of Cooperativa Multiactiva Sur Oriental, a solidarity association centered on urban agriculture in Bogotá, Colombia. Despite being strengthened with agricultural expertise, this association lacks an administrative scheme for proper resource management to generate surpluses and social development benefits for its members. Through participatory action research, the study aims to strengthen the cooperative's administrative and accounting processes to improve its urban agriculture business.

Sjsu ScholarWorks, Gabriel R. Valle · · United States

This paper explores the self-valorization of work in community gardens as a path to environmental justice, arguing that community gardens disrupt capital's system by removing food as a commodity and revaluing time outside market-driven speed. The Chicano community, being susceptible to workplace inequalities, has a particular stake in this self-valorization, as these inequalities are reflected in unhealthy communities, economies, and environments. The study suggests that self-valorization through work creates natural wealth, reconstructing time, oppression, and communities.
