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 article presents initial results from a bibliographic review on Urban Agriculture (UA) to support a research agenda in the metropolitan regions of Pará State, Brazilian Amazon. The review analyzed concepts, approaches, and challenges in national and international literature. It concludes that UA needs to be problematized within the phenomena of urban-regional space production, which cause socioeconomic and spatial inequalities, representing the greatest structural difficulties for urban agriculture.

This article reviewed three edible living wall case studies in Gauteng, South Africa, focusing on system resilience, economic feasibility, and edible plant possibilities. Interviews were conducted with clients, contractors, and designers. Findings suggested indirect commercial value through customer experience and educational value, but indicated that economic feasibility and resilience need enhancement for improved urban food production.

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 case study investigated the cognitive demands and work complexity for urban organic farmers whose main economic activity is selling their products. The findings indicate that the cognitive load for these farmers is high, contributing to complex work. The study notes a lack of existing research on the cognitive load of organic urban agriculture workers, as it is still a nascent movement.

Pratik Mishra, Sumit Vij · · India (Gurugram)

Ethnographic research in Budhera, a peri-urban village bordering Gurugram city in Haryana, India, investigated the juxtaposition of urbanization processes and climate variability impacts on peri-urban agriculture. Results showed that dimensions of agrarian livelihoods, such as cropping choices, irrigation cycles, sharecropping arrangements, declining common property resources, and land use changes to non-agricultural uses, were influenced by urbanization processes. It was concluded that changes in land and water use reshape agricultural practices and can cascade upon climate variability impacts, making agriculture more precarious for peri-urban farmers.

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.

Manuela Maluf Santos, Paulo Eduardo Moruzzi Marques · Estudos Avançados · Brazil (São Paulo)

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.

Pastory Salvatory Thomas, Wilbard Kombe, Aldo Lupala · Urban and Regional Planning · Tanzania

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.

Paul D. Jensen, Caroline Orfila · Food Security · United Kingdom

This case study used publicly available data to spatially analyze the urban food system of Leeds, UK, assessing its food security and resilience. The study found that while Leeds has a significant food production and provision system, it is not food secure in terms of providing sufficient energy or macronutrients, nor does it function equitably for all residents. Improving the system, including through urban farming, would require high investment, multi-sector cooperation, and strong governance.

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.

A study of agricultural land in the Yakatoot area of Kabul, Afghanistan, examining the economic and environmental impacts of land-use change in the capital. It states plainly that, due to rapid population growth, population densification, and the city's inability to enforce its master plan and regulations, a large portion of agricultural land cover has been transformed into unplanned developments, shifting communities from productive societies into consumer and dependent ones. Using a qualitative approach combining field surveys, aerial photographs from Google Earth, and data from CRIDA, the study describes Afghanistan's land laws and identifies the social, economic and environmental impacts of this land-use change, while also reviewing international experience with land-use change and sustainable responses. The authors recommend incorporating urban agriculture practice into Kabul's master plan and other urban initiatives, though this recommendation is presented as the paper's own policy proposal rather than a measured outcome.

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.

A review of the rhizosphere as a microhabitat of intense chemical dialogue between plants and microorganisms covers synergistic interactions that can enhance plant function and productivity, including responses to stress conditions such as heavy metal (HM) contamination, alongside the risks such contamination poses. Where heavy metals are present in agricultural soils, there is a risk of metal uptake by edible plants leading to bioaccumulation in humans and animals with detrimental health consequences, and plant productivity itself can be negatively affected; many bacteria have defensive mechanisms for resisting heavy metals and can improve plant responses to HM stress, but achieving such beneficial rhizosphere interactions is described as hard to attain in agroecosystems managed with traditional practices that focus on maximizing crop yield.

A study developing a framework and overview of key factors, policies, and barriers associated with rooftop urban agriculture (RUA) integration, based on stakeholder perspectives in four European cities—Barcelona, Berlin, Bologna, and Paris—via a two-phase workshop and stakeholder survey. While education, environmental, research, technological innovation, food production, and social factors were found to play an important role in implementing RUA, the cost of water and pollution emerged as major contextual factors constraining it. Policies related to food trade and urban planning were the most limiting to RUA development, and major architectural and technical barriers were identified around building height limits, historical buildings, lack of specific building codes, and roof accessibility, with high infrastructure costs and policies prohibiting RUA product sales acting as economic constraints. The cities differed significantly in the perceived effect of urban policy on RUA diffusion and the perceived relevance of economic and pollution factors, and the study concludes that wider dissemination of RUA information and new or revised regulations and building codes are needed.

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.
