This paper analyzes Japan's teikei movement (Japanese CSA) and how it exemplifies diverse economies. Through case studies of two teikei groups in the Kansai region, it assesses how changes made by current generations allow teikei to adapt to long-standing challenges, such as the decline of volunteer labor. Despite current members' detachment from strong activist identities, they sustain their organizations through part-time work, community building, and institutionalizing volunteer labor.

Sofia Nikolaidou · Cahiers de la Méditerranée · Greece (Athens)

This article analyzed the role of peri-urban agriculture and alternative food networks (AFN) in the Athens metropolitan area, Greece, using a mixed method approach including qualitative, quantitative research, and spatial data collection. Bottom-up claims for food security positively impacted sustainable food systems and public policies, while informal retail channels and self-production schemes strengthened agricultural resilience. However, poor land management and zoning control are major constraints to sustainable agricultural production and farmers' resilience in the Athens metropolitan area.

This paper critically examines urban experimentation for sustainability, arguing that urban experiments are often assessed from a diffusion-oriented perspective that over-emphasizes unifying visions and neglects unsuccessful initiatives. Using a novel methodological approach combining a metropolitan geodemographic typology with qualitative data on 166 active and inactive urban agriculture initiatives across London, the paper demonstrates that neglecting the diversity of urban socio-economic, demographic, and physical contexts may lead to the erroneous suggestion that only demographically privileged places can achieve sustainability. It highlights that contextual differences at neighborhood levels significantly influence socio-spatial patterns of experimentation.

An experiment over six weeks investigated the impact of traffic noise pollution on plant growth in urban community gardens. Plants exposed to traffic noise showed significantly reduced average height (65.6 mm vs 104.2 mm) and weight (0.85 g vs 1.31 g) compared to those in natural noise conditions. The study found a statistically significant deteriorating effect of traffic noise on plant growth.

Akeem Ola · Town and Regional Planning · Nigeria (Ilorin)

This study examined the effects of urban planning practices on urban agriculture (UA) in Ilorin, Nigeria, and its contribution to the city's food shock resilience. Findings revealed that UA contributed 16.9% to meat/fish/egg requirements, 4.5% to yam/cassava/potato, 0.58% to vegetables, 0.6% to fruits, and 0.5% to grain requirements. However, the Respondents’ Agreement Index (RAI) indicated that poor access to finance (0.93), limited land area (0.75), and lack of tenure security (0.44) were dominant variables influencing UA's poor contribution to food security.

This report, part of the SAT-CV-CBA Project, aims to inform provincial authorities and the community about the estimation of horticultural areas affected by extreme weather events in Córdoba, Argentina, at the end of January 2021. It estimates the number of farms, crop losses based on vulnerability, and storm intensity. The information is expected to be useful for supporting affected producers.

Cecilia M. Tsu · Amerasia Journal · United States

This article examines community gardens established for refugees from Vietnam, Cambodia, and Laos in the United States during the 1980s. It argues that refugee gardeners perceived a significant disconnect between their rural lives in Southeast Asia and the role of vegetable growing in the U.S., despite advocates emphasizing continuity with their past. The gardens provided a measure of economic empowerment, but highlighted the disjuncture in their resettlement experience.

This paper contextualizes relevant experiences and technical tools for implementing urban and peri-urban agroecological orchards in Colombia. It notes that urban and peri-urban agriculture can alleviate food insecurity and create jobs, but currently, Colombia lacks government policies to support these processes. The study aims to transfer knowledge on crops to communities to strengthen food security through vegetable production.

Glenda Elizabeth Gilmore · Southern cultures · United States

This article examines urban gardening practices by women in the New South during the early 20th century, which provided self-sufficiency and profits. It chronicles how urban planners and zoning eliminated most of these urban gardening opportunities by the late 1930s. The study considers these practices through two collages by artist Romare Bearden, focusing on the gardener Maudell Sleet.

Camille Frazier · Hong Kong University Press eBooks · India (Bengaluru)

This paper examines motivations for organic terrace gardening among middle-class individuals in Bengaluru, India, who grow food for home consumption. Gardeners respond to worsening health and environmental conditions, but class and caste inequalities limit their engagement with a broader community of urban food producers. These inequalities restrict the transformative potential of organic terrace gardening as an intervention, indicating a critical finding regarding equity.

James J. Connolly, Isabelle Anguelovski · Frontiers in Ecology and Evolution · United States

This study used state sequence analysis to examine the historical trend of greening (including parks and community gardens) from 1975 to 2014 in nine U.S. cities, in relation to concentrations of white and non-white residents. Findings revealed that the relationship between greening and race/ethnicity varied by city-level growth trajectory. Cities with continuous high growth showed the strongest link between increased greening and whiter populations, while non-white areas in cities with contraction or punctuated growth exhibited uniformly low levels of greening, mostly in recent years.

Mkwela Hawa · Journal of Geography and Regional Planning · Tanzania

This study used a qualitative approach to examine land injustices faced by urban farmers in Mbweni-Mpiji, a sub-urban area of Dar es Salaam City, Tanzania. Findings indicated that farmers experience constant pressure from land insecurity, inferior land rights, informal land access, stiff competition from other land users, degrading land quality, and a continuous decrease in agricultural land size. These factors negatively impact the daily livelihoods, including food security, social status, and income, of those entirely dependent on urban farming.

This paper analyzes Thomas Kling’s poem „geschrebertes idyll, für mike feser“ as an "allotment garden idyll" within 'new nature poetry'. While Kling skillfully engages with the idyll genre and offers ecological, social, medial, and historical critique, the study finds that he presents a decidedly patriarchal self-image, which contemporary readers would likely find less acceptable.

This study aimed to identify the impact of visit frequency to community gardens in Slovakia on members' perception of membership importance, satisfaction with community relations, perceived improvement in social relations, and influence on quality of life. A mixed-methods approach, including a questionnaire survey and semi-structured interviews, was used. The analysis did not confirm a dependence between visit frequency and the gardens' impact on members' communities, and found no statistical relationships between the variables in the analyzed data set. However, members positively rated relationships within those communities.

Cecília Delgado · RPER · Portugal

This article examines the potential for urban agriculture practices to foster food policy formulation and implementation in Portugal. An inquiry involving 16 local municipalities identified constraints and opportunities for local initiatives. The study argues that Portuguese civil society's relative fragility, compared to other countries, may explain the lack of local public food policies, despite confirming national and local opportunities.

Daren Shi-chi Leung · China Perspectives · China (Guangzhou)

The Chinese community-supported agriculture (CSA) movement advocates for peasant farming and food sovereignty, promoting "ethical" food often through intermediary certification. However, controversy exists among CSA activists who question the effectiveness of certification in improving consumer-producer relationships. This paper presents an alternative approach focusing on strengthening participatory culture within the consumer-producer nexus, based on an empirical study of Chengxianghui (CXH) in Guangzhou and outlining a "convivial agriculture" framework.

The "Ecotopia" concept, promoting ecologically and socially responsible American Appropriate Technology (AT), included innovative urban planning like rooftop gardens. However, the expansion and contraction of the intranational Ecotopian network built by former Rainmakers in the mid-to-late 1970s revealed a crisis of purpose within RAIN and signaled a crisis within the AT Movement itself.

Tenri Ulfa, Nurlita Pertiwi · UNM Environmental Journals · Indonesia (Makassar)

This descriptive quantitative and correlational study of 50 respondents in Makassar City examined urban farming behavior and influencing factors. While respondents generally had high environmental knowledge, their environmental attitudes were moderate. 23 respondents with low urban farming activities cited time constraints as a difficulty, despite a significant, strong, and unidirectional relationship found between knowledge, attitudes, and behavior.

Lucia Di Paola · · Italy

This paper examines Milan's Porta Nuova re-urbanization project (2004-2015), which features Vertical Forest skyscrapers as symbols of urban greening. Activists and resident groups strongly opposed the project, criticizing the privatization of a public park and high rents, arguing it represents a top-down privatization leading to exclusion and gentrification. In response, these groups developed a public community garden in the same neighborhood as an alternative model for democratic horizontal urban greening.

Fabio Amato, Lucia Simonetti · Journal of urban regeneration and renewal · Italy (Naples)

This paper focuses on the social urban garden in the Ponticelli neighborhood on the eastern outskirts of Naples, Italy, an area facing significant social and cultural problems including high unemployment and crime rates. The urban garden demonstrates how social cohesion can be built through urban agriculture and contribute to sustainability. However, the initiative risks remaining isolated and providing limited benefit to regional environmental sustainability efforts if not framed within an overall metropolitan strategy.

Arthur Feinberg, Elena Hooijschuur, Nicole Rogge, Amineh Ghorbani, Paulien Herder · Journal of Artificial Societies and Social Simulation · Europe

This paper presents an agent-based model to explore conditions for sustained participation in urban community gardening projects in Europe, validated with data from Germany and the Netherlands. The study found that not all of Ostrom's Design Principles for collective action lead to higher participation; instead, participation depends on specific combinations of these principles. It also highlights that sanctioning mechanisms are not always beneficial and can be counter-productive in certain contexts for volunteer participation.

Heavy metal (HM) and metalloid concentrations were assessed in 200 urban horticultural soils across ten UK cities. HM were found to be widespread, with most concentrations below UK soil screening values (C4SLs). However, 83% of lead (Pb) concentrations exceeded C4SLs, which is a significant concern. Bioavailable HM concentrations represented a small fraction (0.01–1.8%) of total concentrations, and black carbon (BC) and organic carbon (OC) were suggested to contribute to HM immobilization.

Nancy Karanja, Mary Njenga · · Kenya (Nairobi)

The urban agriculture efforts of Alice Wairimu and her husband Michael Macharia, who migrated to Nairobi, Kenya, are presented. They raised livestock but lost a cow during political unrest and sold the rest for hospital bills. They also attempted wastewater farming on government-owned land, which was repossessed in 2010. Subsequently, they used their meager savings to rent land nearby and continue practicing urban agriculture.
