This article compares urban and peri-urban agriculture (UPA) in Regente Feijó, Brazil, and Centre Wellington, Canada, to understand their particularities and contributions to food security and local food supply. Data from interviews with farmers revealed that while production purposes differ—predominantly self-consumption in Regente Feijó and commercialization in Centre Wellington—UPA significantly improves food security and local supply in both areas. A key challenge identified is the inadequate government support for UPA in both studied regions.

This chapter examines the relationship between urban activism and the establishment of non-commercial community gardens in public spaces within São Paulo, Brazil, since 2010. It details the formation of the "Hortelões Urbanos" activist network in 2011 and the subsequent creation of the "União de Hortas Comunitárias de São Paulo (UHCSP)" in 2018, which unites community garden initiatives. The analysis highlights how these gardens, despite the absence of municipal public policy, promote health, healthy eating, autonomy, and urban biodiversity through low-consumption practices.

This qualitative-quantitative study characterized school gardens in public education networks across twenty-four municipalities in Brazil's Serra Gaúcha region using a semi-structured questionnaire. Data revealed most schools were located in urban areas, predominantly served elementary school students during the daytime, and lacked guidance from qualified professionals and agroecological management for their gardens. Based on these findings, four educational brochures on agroecological techniques were developed for elementary students.

A systematic review of 34 studies (37 articles) from 2000-2020 evaluated the impact of local food system (SVC) models on food and nutrition security among low-income populations in the United States. Farmers market interventions were more extensively evaluated than other SVC models, with fruit and vegetable intake being the most measured outcome. Barriers to SVC use included lack of program awareness, limited accessibility, and cultural incongruence, while facilitators included health-promoting environments, community cohesion, financial incentives, and high-quality produce.

A study of 18 urban community gardens in Central Coast, California, USA, used gardener surveys and field measurements to evaluate food production and its distribution. Gardeners produced an average of four pounds of food per week, saving an estimated $16 USD weekly. However, gardeners with greater food insecurity (larger families or lower incomes) were not the largest producers, indicating uneven benefit distribution despite high overall productivity.

This study reviewed and categorized 73 food asset maps in Canada based on their included food assets and design characteristics. Most maps included built environment assets like grocery stores and food banks, as well as agriculture-based natural food assets such as farms, community gardens, and orchards. However, representations of Indigenous-focused food assets and non-agriculture-based natural food assets like forests, water bodies, and foraging areas were generally lacking. This lack of Indigenous perspectives reinforces the values of a settler-colonial food system within food asset maps.

Finn Bell · Critical and Radical Social Work · United States (Ypsilanti)

This qualitative study explored how marginalized agrarian traditions can aid communities in surviving climate change, conducting in-depth interviews with 23 marginalized food growers and community leaders in Ypsilanti, Michigan. The study found that while growing food builds resilience to food insecurity and climate change, it is difficult due to land injustice. Policy implications include the need for housing justice, proactive planning for climate refuges, and reparations for land rematriation.

Delf Rothe · Political Geography · United States (New York City)

This paper critically examines the concept of "green resilience" through a case study of various green resilience projects in New York City, including survivor trees, memorial groves, and community gardens. The study argues that these spaces function as key forms of state rule and biopolitical power, identifying three tensions or contradictions of green resilience as a form of biopolitical government: visibility and invisibility, knowledge and ignorance, and control and emergence.

This article reviews the role of urban agriculture in improving food and nutritional security for vulnerable populations in Brazil, where 33.1 million people lacked guaranteed daily food in 2022. It highlights urban gardens as an alternative to enhance access to healthy food. The study suggests that maps, data, and strengthened public policies can promote urban gardens as food cultivation spaces in urban and peri-urban areas, forming networks to combat hunger.

Brandon, Chrislyn · Scholar Commons (Santa Clara University) · United States (Santa Clara)

The City of Santa Clara faces significant challenges in ensuring equitable access to food for its residents amidst rising living costs and economic disparities. Enhancing support for residents' food security needs through increased knowledge sharing and resource provision in community areas is an efficient strategy to reduce hunger rates and create welcoming community spaces that support sustainability. This initiative addresses two key focus areas in Santa Clara's Climate Action Plan.

This online survey of 394 urban growers, primarily in the Northeastern United States, profiled growers and assessed urban agriculture's state, identifying needs and challenges. Most growers were white (non-Hispanic), under 45, well-educated but without agriculture degrees. Urban agriculture was dominated by small non-profits and home/community gardens. A critical finding is that urban growers face diverse barriers, with the most common being land availability and long-term access in urban areas, and many reported low revenue or operating at a net loss.

This paper presents a methodology applicable to sustainable community actions, developed from seven years of experience with low-income communities in a Brazilian community garden. The methodology is based on participatory action research, systemic design, agroecology, food sovereignty, and solidarity economy principles. The study demonstrates the importance of integrated work among the elements of the quintuple helix model (society, government, industry, academia, and environment), but it does not detail specific challenges or limitations regarding governance.

This article examines the history of urban gardening by Black communities in New Orleans, United States. It uses oral history to complement official documentation, demonstrating that Black New Orleanians historically grew their own food for collective efficacy and to pass on horticultural knowledge. The study notes that most new gardens since 2010 lack cultural and social connection to this history.

A qualitative study of a Conservation Unit in the Brazilian Amazon (the Lago do Cuniã Extractive Reserve) analyzing the role of forests within the water-energy-food nexus, focusing on how traditional populations use non-wood natural resources for their survival. Data were collected through questionnaire-based interviews and non-participant observation. The results show that maintaining forest resources improves water quality, controls erosion and resilience against droughts and floods, contributes to energy supply, and contributes to food safety for residents of the conservation unit. The authors note policy implications for management practices to conserve forests and to protect the quantity and quality of rivers, lakes, and aquatic and agricultural ecosystems in the reserve.

A 2024 paper reports on an educational practice with elementary school students at a community garden at IFG-Anápolis, Brazil, framed around "omnilateral formation" and critical environmental education. Through periodic visits, workshops, and discussion sessions, the practice addressed problems arising from the use and consumption of pesticides in food. It reports that the critical environmental education approach was significant in revealing the latent meanings behind an agribusiness food market based on unrestrained pesticide use.

This article examines the Seeding East Buffalo Fellowship (SEBF) program, co-founded by community and academic organizations in Buffalo, NY in 2022, which supported residents of Buffalo's Black neighborhoods in growing their own food, emerging as urban agriculture leaders, and engaging in urban agriculture policy advocacy. The authors, who are co-founders or team members of SEBF, draw on field notes and qualitative interviews with SEBF growers to reflect on lessons from this pilot program. Key lessons for policy change identified are that programs must be rooted in community history, pedagogical strategies must be tailored to local context, and long-term relationships must be fostered.

A study examining agricultural activity, in particular family farming, in the Fortaleza Metropolitan Area (FMA) of Ceará State, Brazil. Drawing on primary and secondary data on producer profiles and agricultural and food-processing establishments in the region, it identifies key issues in production and food systems within the FMA. The study presents the production strategies used by family farmers, the challenges they face, and opportunities they identify, and argues that examining agriculture in metropolitan areas links socio-spatial and socio-environmental problems and points toward cross-sectoral public policy.

A critical examination of urban agriculture governance in Seattle, Washington, USA, tracing the geographic, social, agricultural and governmental context of city policy. Seattle established its P-Patch community gardening program in 1973, and grassroots and community organizations have worked on food production and food security since the early 1970s, but the city government did not begin systemic policy engagement until the early 2000s. Using a critical lens, the chapter examines key policies - including urban agriculture zoning regulations and the Local Food Action Plan - and projects such as the Rainier Beach Urban Farm & Wetlands Project, to assess the impact of urban agriculture policy on racial, social and health equity.

In mid-2021, a 400 m² "productive backyard" (quintal produtivo) was set up at the Fazendinha Agroecológica km 47 in Seropédica, Rio de Janeiro state, Brazil, run jointly by Embrapa, UFRRJ, and PESAGRO-Rio, with four subareas for vegetables, unconventional food plants (PANC), fruit trees and annual crops, and egg-laying hens. Food production recorded over six months of 2021 demonstrated the plot's potential to counter food insecurity by supplying a healthy, diversified diet and generating extra household income through the sale of surplus produce.

Two community urban gardens in Mexico City were analyzed through the lenses of agroecology, the social and solidarity economy, and social innovation. Working with garden administrators and key participants, the researchers defined participatory indicators and ran workshops to gauge local perceptions of how the gardens function. Both initiatives were viewed positively by their communities, though few residents were actually involved. Most evaluated variables scored satisfactorily, but aspects such as the source and use of water, income distribution within the community, and the creation of communal budgets had not met their objectives.

Nick DeMarsh, Alfonso Morales · Urban agriculture · United States

Focused on cities in the United States, this paper (2024) frames urban agriculture as an opportunity to challenge the status quo of current urban and food systems, discussing the opportunities and challenges that increased urban population and density create for it through Howe and Kaufman's ethical framework of means and ends. Noting the tendency for ethical ends (economic or other outcomes) to preempt consideration of ethical means or processes, it applies this means-and-ends framework to propose three key ideas for framing the ethics of urban agriculture: a place-based historical perspective, a bridge connecting cities and regions, and a nested approach to reimagining healthy socio-ecological systems. It argues that urban agriculture practitioners must understand the history of urban places and agricultural processes both as consequences of national historical processes and in present place-specific contexts and future orientations; that urban agriculture's contribution to an environmentally sustainable future rests on recognizing food production and consumption as an essential part of human life; and that its transformative potential stems from its significant role in the urban and food systems that shape everyday life — while cautioning that this potential does not mean change through urban agriculture is inevitable, since it requires participants and stakeholders to critically examine their own practices and expectations.

In New Jersey, 50 food desert areas face the most severe food insecurity across both rural and urban contexts. This study identified nine barriers to implementing urban agriculture initiatives in New Jersey's urban food deserts, using a sequential quantitative analysis combining a survey of food systems professionals with a GIS-based spatial analysis to identify the most prevalent barrier. Working in partnership with New Jersey urban agricultural organizations, the study found that lack of funding was the most commonly cited barrier to expanding urban agriculture initiatives. The GIS-based spatial analysis found that high-priority barriers varied by region, but that all organizations identified funding, or lack of access to funding, as a significant barrier regardless of whether they operated in a low- or high-income neighborhood. The study concludes that policymakers must reevaluate the role of urban agricultural organizations in New Jersey's urban food deserts.
