This study explored the potential and limitations for agroecological scaling through formal educational structures, using the LabVida school gardens program in Chiapas, Mexico as a case study. Through training, educators gained an appreciation of agroecology and applied practices in their school gardens, although their understanding of agroecological principles and scientific process remained limited. The program's greatest impact was on educators’ eating habits and their perception of the value of local knowledge and its relevance to schoolwork.

This study in Baltimore, Maryland, used GIS mapping and spatial analysis to assess the proximity of urban farms to environmental hazards, including those with heavy metal contamination. Analyses indicated that contamination of urban farms is a possibility due to proximity: more environmental hazards were found in census tracts with urban farms, and low-income communities of color had hazards near urban farms. Historically industrial areas showed a higher concentration of environmental hazards with heavy metal or unknown contamination.

In Venezuela, the Bolivarian Revolution since 1999 has seen the unfolding of harsh class and food system contradictions. While the Program Degree in Agroecology (PDA) at the Bolivarian University of Venezuela has trained over a thousand graduates who contribute to agroecological scaling and urban agriculture, the abstract highlights the persistent "harsh class and food system contradictions" within the country. This indicates ongoing equity challenges despite agroecological efforts.

Viktoria Shchurova · Current problems of architecture and urban planning · Ukraine (Kiev)

This article highlights the problems of the negative impact of the agricultural sector integrated into the central and middle zones of large cities. A critical view was formulated on the practical implementation of scientific and legislative documents, using the example of the city of Kiev, and strategies for reorganization, restrictions, or a complete ban on estate development in urban environments were analyzed. Specific plots of estate development in Kiev were identified as requiring reconstruction or complete renovation in accordance with the city's strategic development concept.

This study in Baltimore, Maryland, used GIS mapping and hotspot analysis to assess the proximity of urban farms to environmental hazards. Most urban farms were located in low-income communities of color. However, most environmental hazards were not near urban farms but in predominantly White areas or historical industrial centers. Despite a generally low risk of contamination, some urban farms in low-income and Black/African American communities were potentially contaminated by hazardous sites.

This qualitative study explored human assets among 8 participants in community garden projects in Malaysia. While the government introduced community garden projects to improve urban residents' well-being, their success rate is reportedly low, with many projects expected to be unsuccessful. The study found that participants possessed human assets such as good health, physical strength, ability to seek agricultural inputs and information, strong religious practices, and resilience.

A community empowerment program focusing on clean water management, compost making, and urban farming was implemented in Muara Baru flats, Jakarta. A majority of residents responded positively to the program and expressed willingness to actively participate. However, several obstacles hindering the program's success were identified, including a lack of commitment from the local community, climate change, water availability, and arable land availability.

Farmers’ markets, Community Supported Agriculture (CSA) programs, and community gardens, while aiming to help low-income families access fresh produce, often assist more middle-class families. In Utah, these programs could be improved, as the state does not utilize the WIC Farmers’ Market Nutrition Program or accept WIC Cash Value Vouchers, and has few Farm to School Programs.

This article conceptually explores the "locavorism" food activism movement, noting that its practical application can have diverse and even antagonistic effects. To analyze these contradictions, two farmer organizations in São Paulo involved in local consumption circuits were interviewed to understand the potential social and environmental effects of this purchasing model. The abstract does not present the findings of these interviews.

This qualitative study examined perceptions of urban agriculture among 60 urban farmers and officials in Arusha City, Tanzania, through interviews, observation, and literature review. Findings revealed that negative effects of urban agricultural activities influenced negative perceptions, which city officials seldom managed. While urban agriculture is acknowledged in policy, the critical effects of negative perceptions among stakeholders are considered less crucial in policy implications and formal governmental proclamations, despite their real-world impact.

Implementation strategies for food-energy-water production systems on urban rooftops were evaluated in a typical housing estate in the Metropolitan Area of Barcelona, comprising 201 buildings and 13,466 inhabitants. Residents tended to choose strategies providing energy and water over the food production potential of rooftops. However, environmental assessment indicated that vegetable production alternatives were the least impactful, meeting 42-56% of residents' fresh produce demand and reducing environmental impacts by 24-37 kg CO2 eq m-2 per rooftop per year. This suggests residents were primarily concerned with energy expenses rather than food insecurity or social cohesion.

Rebecca Amato · Amsterdam University Press eBooks · United States (New York City)

This chapter discusses the historical production and perception of "empty space" in New York City, from settler colonialism to gentrification, driven by techniques like filtering and declaring vacancy. It highlights how the acceleration of development to maintain world city status threatens alternative visions like cooperative centers and community gardens. These alternative uses are presented as models for inclusive cities, despite being under threat.

A study noting that although exposure to green space benefits residents' physical and mental health, its spatial distribution is inequitable, and that existing green equity studies typically rely on administrative units, a macro-scale approach that overlooks the fine-scale green spaces (such as community gardens and lawns) residents encounter most often, risking biased estimates. Using the community as the unit of analysis, the study drew on three types of green-space data - fine-scale green spaces within communities, surrounding large-scale parks, and streetscape imagery - and applied a proposed set of 11 metrics across morphology, visibility, and accessibility to 4,544 communities in urban Beijing. Through spatial visualization, spatial clustering, radar plots, and correlation analysis, the study found large differences and complementary relationships between metric categories, similarities within the same category, and confirmed inequity in green space across regions of the city as urbanization proceeds.

In the "Heavy Metal City-Zen" citizen science project, community members in urban gardens in Vienna, Austria collaborated on collecting soil and plant samples to assess heavy metal contamination risk. Trace metal concentrations were generally below guideline thresholds, but at a few garden sites soil concentrations of lead, cadmium and zinc exceeded Austrian recommended limits, and at two sites plant trace metal concentrations exceeded European food standard limits; the project proposes expanding the citizen-led sampling to all of Vienna so new gardens can assess local soil risk before planting.

Amid a COVID-19 outbreak that caused 15,587 deaths in São Paulo city through December 2020, this study examined effects on urban agriculture from April to August 2020, drawing on two government surveys (2,100 farmers in São Paulo state, 148 in São Paulo city) and two qualitative surveys of volunteers from ten community gardens and seven urban farmers. Fifty percent of farmers reported being affected by the pandemic through drops in sales, particularly those who depended on intermediaries, and 22% said obtaining inputs had become difficult. No municipal support was provided to urban agriculture in São Paulo, and pre-existing problems worsened; activity in community gardens declined, though none closed permanently.

This chapter examines the 2000s housing financialization wave in Hungary, analysing financial over-inclusion and exclusion -- alternating dynamics of reaping gains and externalizing costs. It shows that "intermediate" rural-urban transitional zones are prime areas for high-risk mortgage lending while also containing spaces excluded from institutionalized housing finance, using as its case study an allotment garden where households combine formal jobs and mortgage repayment with informal dwelling to reduce housing costs, arguing that such informal reproductive solutions function as a resource for capital accumulation through inclusion and exclusion.

A study on Malaysia's Movement Control Order (MCO) noted the extension may effectively contain the pandemic's spread but is expected to have a devastating impact on food security, and proposed urban farming as a means of generating household income and food security for the low-income B40 group. Econometric modeling of the effect of lockdown measures and COVID-19 on selected vegetable prices found that not all vegetables reacted uniformly to lockdown measures; price increases were associated with reduced household purchases and income, denying people access to food security. While the substitutability of vegetables allowed some switching to cheaper options, the study states that higher food prices themselves deny people access to food security.

Elia Apostolopoulou · · Europe (Greece)

Focusing on the two largest Greek cities, Athens and Thessaloniki, this study examines why urban community gardening surged after the 2008 financial crash, drawing on urban political ecology, radical social and urban geography, and qualitative social research. Greece is treated as a distinctive case: it saw this post-2008 increase in community gardening without having a prior long history of the practice, unlike parts of the Global South. The author concludes that the creation of community gardens is tied to rising inequality in European cities in the aftermath of the 2008 crisis, functioning both as an act of disobedience against the grabbing of public land and as a demand for reclaiming the urban commons.

In-depth interviews with community supported agriculture (CSA) farmers in the Pioneer Valley of Massachusetts, United States, examined their livelihoods. CSA farmers earned more farm income than other US farms and other farms in the region, but their earnings remained far below the median national household income. Despite this income shortfall, CSA farming provided non-market social, ecological and economic benefits tied to feeding the community rather than producing for mass markets, which farmers described as a significant source of well-being.

A reflection on a citizen science project in which five early-career and PhD female researchers guided school-age children across five schools to build artificial flowers, install them on school ovals, and record over repeated 10-minute observations how flower colour (yellow vs. blue) and configuration (isolated, clumped adjacent, clumped mixed-colour, clumped single-colour) affected the number and taxa of visiting insects. The project achieved a low-cost, engaging format and exposure to female STEM role models, but the authors report constraints including having to run it in a season made suboptimal by fixed school curricula, confounding of results caused by the children's own observations, and an inability to verify the collected data.

This study in Makurdi, Benue State, Nigeria, used geospatial technology to assess agricultural land vulnerability to flooding, deriving factor weights (rainfall 25%, elevation 22%, slope 20%, drainage density 13%, land use/cover 12%, soil type 8%) through pairwise Analytical Hierarchy Process comparison (consistency ratio 0.078) and a weighted overlay model in ArcGIS 10.4. Farmland along the floodplains of the River Benue fell within the very highly vulnerable category, with elements at risk totaling 537.6 units of farmland (66.1%), 40.5 units of irrigation land (5.0%), and 125.8 units of built-up land (15.5%).

This case study examines the leading edge of gentrification along San Francisco's Third Street T streetcar line. Bayview-Hunters Point (B.V.H.P.), the end of the streetcar line's first phase, is an ethnically mixed, working-class neighborhood and the last historic concentration of African American residents in San Francisco. While gentrification-driven change is already visible further up the line, its presence in B.V.H.P. remains comparatively shallow so far. Nonetheless, many residents and community activists perceive that a fast-moving gentrification frontier leaves them with a conundrum: remain in a contaminated, post-industrial, climate-exposed environment, or advocate for their health while risking displacement. The neighborhood has seen greening such as community gardens and a waterfront promenade, alongside inequalities including enduring racial segregation, environmental privilege, green gentrification, luxury development, climate-related health risks, and continued exposure to contamination.

This chapter analyzes the regional class and caste politics of large-scale land investment in Maharashtra, India, through the case of the Khed Special Economic Zone (SEZ), where peri-urban agricultural land was converted into urban real estate. Dominant agrarian castes, long invested in commodity agriculture and closely tied to urban capital, protested vociferously against land acquisition for the SEZ, while Adivasi ("tribal") and Dalit groups historically dependent on land classified as "waste" embraced the forced acquisition. Historic narratives linking poor land quality to the social backwardness of those occupying "wasteland" were leveraged by these lower-caste and lower-class groups themselves to frame land expropriation as a path into the urban economy. The chapter concludes that fictions of "waste" that had previously excluded the most socially subordinated groups from commodity agriculture became, in this case, an instrument of urban inclusion.

A qualitative sociological analysis examined a policy tool used by public landowners in peri-urban Milan, Italy, who introduced new lease agreements transferring the maintenance costs of built rural heritage to tenants, aiming to avoid degradation and add value to unused buildings. Analyzing the tool through the lens of social justice and its impact on quality of life, the study found that the same policy tool produces very different outcomes for landscape preservation and quality of life depending on the implementation strategy used, and on the elements of social justice considered along with contextual and individual characteristics.

A study of Virtual School Garden Exchanges (VSGEs)—which link local gardening with global thinking by having elementary and secondary school students in different parts of the world exchange information about their school gardens and related topics via digital media—focused on educators' perspectives and the learning outcomes they observed, given ongoing controversy over whether VSGEs are suitable for Education for Sustainable Development (ESD) and whether they produce the learning outcomes educators expect. The researchers conducted 20 semi-structured interviews with VSGE educators, analyzed abductively and qualitatively. Results showed substantial overlap between observed and expected learning outcomes and ESD aims, but the data also revealed that learners engaging with international peers were affected by stereotypes and norms in varying ways: on one hand, VSGEs can lead to "Othering," which is not congruent with either ESD or the expected learning outcomes; on the other, they can inspire Transformative Learning that contributes to ESD aims. The study concludes that VSGEs hold potential for ESD depending on a complex interplay of factors, but are not guaranteed to constitute good ESD practice.
