The "Grow Your Groceries Home Garden" intervention program, implemented in Chicago, United States in 2022, aimed to improve food access in food-insecure communities. A longitudinal investigation over two annual cycles surveyed 46 participants, complemented by focus groups with 9 participants, to evaluate food access, cost savings, health, and socioemotional outcomes. While results on improved gardening confidence over time emerged non-significant, participants reported increased food access, cost savings, healthier eating, stress reduction, and strengthened relational bonds.

Carlos Luiz Vieira · · Brazil

This study analyzes protected cultivation and hydroponics in Brazil as technologies enabling full control of environmental variables and eliminating dependence on climate seasonality. These technologies demonstrate 80-95% reductions in water consumption, 300-500% increases in productivity compared to open fields, and complete elimination of agrochemical residues. However, the study also points out implementation challenges for these technologies, concluding they are fundamental for food security in contexts of accelerated urbanization, water scarcity, and global climate change.

This chapter examines how local food systems can empower Black farmers and growers through direct-to-consumer and community-based markets, analyzing tools like farmers’ markets and urban agriculture. While case examples show Black-led initiatives, persistent barriers include limited capital, discriminatory pricing and lending, bureaucratic gaps, and uneven USDA support despite civil rights settlements. The study details these challenges.

Miguel Ángel Monteverde-Ávalos · Alteridades · Mexico (Ecatepec)

An ethnography of a dispute over a small community garden in a working-class neighborhood in Ecatepec, Mexico, revealed that internal socialization processes establish thresholds of respectability, leading to classifications that reproduce differential access to public space. The study found that these classifications result in the unequal distribution of spatial resources and contribute to the reproduction of an exclusionary urban order.

Jocelyn M. Leitzinger, Robert David · · United States (Detroit)

A case study of Detroit's urban agriculture market indicates that "business-as-usual" development strategies, which prioritize large-scale investment projects, often fail to achieve their economic development potential. These strategies are noted to potentially exacerbate social or environmental issues, particularly within "moral markets" led by Black activists. The paper explores the mechanisms of such failures and offers recommendations for policymakers and entrepreneurs.

This study analyzed the Capitol Hill Autonomous Zone (CHAZ) in Seattle, which emerged in June 2020 and lasted 24 days, functioning as an urban hub for mutual aid and urban farming. The research, using randomly sampled Fire Department reports, found that CHAZ had significantly higher emergency response rates and incident variability compared to adjacent areas. The zone was dismantled due to outbreaks of violence, including five shootings, two deaths, sexual assaults, and arson, indicating a failure to address communal safety.

Alan da Silva Vinhaes, Tamires Regina Rocha · Revista Tocantinense de Geografia · Brazil (Jundiaí)

This article analyzes the Urban Garden Program in Jundiaí, Brazil, to understand the contradictions between institutional discourse, normative framework, and observed territorial practice. Despite a favorable legal framework, the program's effectiveness is limited by low territorial coverage, a reduced number of active gardens, and reliance on punctual initiatives. The study concludes that long-term public policies with continuous institutional support are needed for urban agriculture to become a permanent component of urban planning.

A choice-based survey of over 600 US residents from Rhode Island examined preferences and perceived value for green rooftop (GR) space allocations for agriculture, solar energy, and recreation. Latent class modeling revealed that Class 1, representing 20% of respondents, was generally unsupportive of GR installation and expressed disutility towards GR space allocation for solar energy. Both classes uniformly favored allocating GR space for agriculture production and showed a positive willingness to pay for this feature.

The 'Braiding Food Systems' project, a community-led partnership with three Northern Ontario First Nations, used mixed-methods Participatory Action Research to examine conditions influencing food security and sovereignty. Community members identified structural constraints rooted in colonial governance, contemporary ecological pressures, and local transformation opportunities. This research demonstrates that sustained, community-led collaboration can counterbalance colonial food systems by reorganizing decisions, strengthening access, and enhancing resilience within Indigenous food networks.

Elisa Carvalho Lauer, Jaqueline Lima Liskoski, Kelliane Da Consolação Fuscaldi · Revista Campo-Território · Brazil

This study mapped and analyzed urban and peri-urban agriculture (AUP) legislation across municipal, state, and federal levels in Brazil, identifying 217 municipal laws in 113 municipalities, 33 state laws, and federal frameworks. The research systematized normative content into twelve thematic categories, showing AUP's integration into food security, urban sustainability, and income generation agendas. While a qualitatively consistent normative basis exists, gaps persist regarding conceptual definition, area guarantees, water access, financing, and credit. It is necessary to expand and harmonize regulations across all three spheres to consolidate AUP as a structural strategy for sustainable cities.

Framed within studies of racial capitalism and neoliberal corporate food regimes, this article examines how residents of Pennsylvania's Monongahela (Mon) Valley experience and articulate food apartheid — a racialized system of food access — and how it intersects with deindustrialization, capital abandonment, and structural racism. Drawing on engagements across three Mon Valley municipalities, the findings reveal complex geographies of food apartheid intersecting with other markers of racial capitalism: inequitable transportation infrastructure, rising cost of living alongside declining quality of life, and ineffective political representation. Residents interpret these inequities as part of a broader racialized economic injustice favoring neighboring, predominantly white municipalities, compounded by distrust of local government perceived as perpetuating exclusionary policies rather than responding to community demands. In this context, participants envision community-driven solutions that extend beyond food system and urban agriculture initiatives.
