NYC's Department of Sanitation began enforcing mandatory curbside organics separation on April 1, 2025, issuing nearly 2,000 summonses in the first week, but Mayor Adams paused broad enforcement through 2025 on April 18, limiting fines to persistent violators. The city had distributed about 190,000 free bins and sold 63,000 more, and organics diversion had risen 65% from FY2022 to FY2024.

Baltimore, United States, has developed urban agriculture policies over the last decade, integrating them into a food systems approach to sustainability. Policy development covered zoning, permitting, land leasing, and soil regulations. However, challenges were encountered regarding staffing, funding, resident engagement, and differing city agency priorities, especially concerning land access. The experience highlights the importance of mainstreaming food policy into urban planning.

This abstract describes a nature journaling session held in a community garden as part of an LGBTQ+ youth summer day camp in Florida in summer 2022. The session took place shortly before new anti-LGBTQ+ laws, including the "Don't Say Gay" law, went into effect, which are intended to erase LGBTQ+ people and histories from schools and highlight the challenges faced by LGBTQ+ educators and youth.

This article presents reflections on the practice of Urban and Peri-urban Agriculture (AUP) and its impact on land use and occupation in Foz do Iguaçu, Brazil. The research raised several questions concerning rural-urban dynamics, the specificities of urban family farmers, and the complexity of land use in the municipality. Diagnostic results from a semi-structured research guide will be used as an empirical basis for further reflection, and the abstract does not state specific research findings or critical findings regarding governance.

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 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.

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.

A report to the Washington State legislature summarizing an advisory committee's research on standards for managing compostable products at composting facilities. Compostable products make up only 0.4% by weight of material sent to commercial compost facilities in the state, yet the associated contamination disproportionately raises processing costs, and consumer confusion is identified as a major driver of misdisposal.

This research surveyed federal and state urban agriculture (UA) laws in Brazil to analyze their implications for urban planning (UP). Findings indicate that despite an increase in approved laws, there is no articulated national policy, laws vaguely address UA's interfaces with UP, and they do not objectively tackle territorial challenges faced by UA.

M. Kühn, Geisa Zanini Rorato, Bruno César Euphrasio de Mello, Carolina Cristófoli Falcão · Ambiente & sociedade · Brazil

This study cataloged and analyzed federal and state urban agriculture (UA) laws in Brazil to understand their profile and association with urban planning. The findings indicate that Brazil lacks a coordinated national policy for urban agriculture. Furthermore, existing laws vaguely mention their interfaces with urban-policy legal frameworks and do not clearly address territorial challenges for UA implementation.

This study of citizen-led gardens in Mexico City reveals that informal urban gardening becomes a practice disconnected from the state. Despite the Mexico City government's interest in regulating urban agriculture, gardeners are increasingly formalizing their practices independently. This disconnection is attributed to a weak institutional context, characterized by top-down policymaking and the city government's incapacity and unwillingness to effectively implement policies, leading to mistrust among gardeners.

This article identified agroecological practices in 10 urban gardens (hu) in Mexico City and their relationship with the construction of food citizenship. Data was collected through interviews with garden managers and users, and participant observation. The study found a tendency to prioritize responsibilities over rights within these urban gardens.

This bibliographical and documentary research analyzed the effectiveness of public food security policies in Brazil between 2012 and 2022, also considering urban agriculture as an alternative. It concluded that public policies were gradually weakened, and from 2019 to 2022, the Brazilian government discouraged food policy implementation. Consequently, Brazil faces food insecurity and hunger due to disjointed policies, the pandemic, and an economic crisis.

California's Little Hoover Commission recommended pausing SB 1383, the state's organics recycling law, citing concern the state will miss its 2025 targets, but CalRecycle, industry and environmental advocates strongly opposed the pause, noting roughly $500 million already invested. 445 of 614 jurisdictions now have residential food-waste collection programs, and waste costs rose 20% for residential and 30% for commercial customers.

A study in Detroit's Lower Eastside (~15 sq. miles) examined the spatial extent, characteristics, and residents' perceptions of urban gardens using spatial analysis and interviews. Gardens covered less than 1% of vacant land and were often ephemeral. Primary obstacles to scaling up urban agriculture in Detroit include uncertainty over land tenure, environmental pollutants, potential ecosystem disservices, and a lack of government support and capital investment.

This study compared 19 municipal urban home food gardening programs in Canada in 2020, which provided free gardening supplies and instructions. It found a complicated relationship between municipalities, gardening programs, and food security, and determined that gardening somewhat alleviated social and emotional challenges from the COVID-19 pandemic. However, municipalities are limited in their policy capacities to adequately address food insecurity in Canada.

A study in four New York cities analyzed the benefits and challenges of community gardens during the COVID-19 pandemic through surveys and semi-structured interviews with community gardeners. Gardeners experienced benefits such as connection, mental and physical well-being, and a safe refuge, but the biggest challenge was limited socializing due to personal behavioral changes and garden rules. This research suggests that while community gardens can be resilient sites of reprieve during crises, the pandemic also exposed their vulnerabilities.

A case study of urban agriculture in Álvares Machado, Brazil, identified challenges including difficulties in accessing land and water for irrigation, the absence of official technical assistance services, and a lack of public policies at national, state, and municipal levels. Despite these difficulties, urban farmers are responsible for a significant portion of leafy greens and legumes production, establishing direct relationships between producers and consumers through markets and street stalls.

This study used the concept of food sovereignty to assess the level of local control over food production, distribution, and consumption in the Mississippi Delta. Research involved site visits, participant observation, focus groups, and surveys of communities affiliated with the Delta EATS public school garden program. Findings demonstrated low levels of food sovereignty, though high levels of agency and ingenuity in accessing desired foods were observed.

This article analyzes an urban collective garden, Horta da Formiga, in Porto Alegre, Brazil, through a two-year participatory investigation using Pierre Bourdieu’s framework. The study found that the more protagonists of Horta da Formiga align with capitals considered legitimate by the state, the more they can reconcile contradictions in this field. However, despite individual agency, participants face structured conditions that do not allow for more organic and diverse forms of contradiction reconciliation.

This study examined local community involvement in governance processes in Milpa Alta, a peri-urban agricultural area of Mexico City, using surveys, interviews, and participatory workshops. It found that Milpa Alta lacks integral adaptive capacity to address urban pressures, environmental deterioration, and agricultural dynamics. Limited participation, low local organizational levels, and distrust of government institutions hinder effective governance, indicating that a "local is not enough" approach is insufficient for adaptive governance in this peri-urban context.

Qazi Shafayetul Islam, Nasima Akter · European Journal of Nutrition & Food Safety · Canada (Toronto)

This qualitative study, involving nine community organization representatives and 15 volunteers in Toronto's priority neighborhoods, identified significant barriers to providing and receiving free food support during COVID-19. Community members faced a lack of information, language barriers, social stigma, and fear of COVID-19. Organizations struggled with insufficient information on needs, limited transportation, storage space, committed volunteers, and funding, highlighting systemic and financial challenges in effective food support programs.

This qualitative study investigated the controversy surrounding urban hen bylaws in Canadian cities, based on semi-structured interviews with 15 urban residents. The research identified three main areas of struggle: the need for education on urban agriculture, differing values for city life, and tensions between individual rights and the collective good. The findings expose challenges in urban hen legislation.
