This chapter considers the challenges faced by school gardens. School gardens often have tenuous links with subjects other than health, nutrition, geography, or science, and practical challenges exist in their establishment and maintenance. Key issues of teacher learning, management of resources, and school identity and ethos are also highlighted regarding school change. The chapter concludes with unanswered questions about the prospects for school gardening, particularly whether and how school gardens might be part of an educational solution to the questions posed by the pandemic and climate collapse.

Miaomiao Xie, Manyu Li, Zhaoyang Li, Meng Xu, Yan Chen, Ran Wo, De Tong · Sustainability · China (Beijing)

This study investigated user profiles and landscape service provision in three urban agriculture parks (UAPs) in Beijing, China, based on 345 interviews. Most users had upper-middle incomes and were well-educated, with social connections varying by UAP type. Findings indicated that the scenery service was not adequately supplied, with 31.5% of areas failing to meet demand, suggesting six landscape types require optimization.

Ana Mélice Dias, Teresa Marat-Mendes · Portuguese National Funding Agency for Science, Research and Technology (RCAAP Project by FCT) · Portugal (Lisbon)

In Lisbon's Greater Area, Portugal, the morphological impact of municipal planning instruments (Municipal Master Plans) on urban agriculture was investigated. It was concluded that current planning regulations prioritize leisure and aesthetic solutions for urban agriculture uses, rather than design solutions that address economic growth or ecological diversity.

Olivia Lee · Johns Hopkins University eBooks · United States (Chicago)

This study, drawing on affect theory, examines community gardens in Chicago's low-income, primarily Black South Side neighborhoods. It argues that while these gardens offer a spatial break from violence, they appear unable to fully counteract the ongoing marginalization by race and socioeconomic status. The gardens represent a quiet, nascent resistance against neoliberal injustices through intimate human-nature interaction.

Ted White · Edward Elgar Publishing eBooks · United States

Non-market sales, barter, trade, donations, and other creative transactions have been integral to Community Supported Agriculture (CSA) since its inception, promoting creativity and new economic thinking due to its advance payment system for unknown harvests. Based on qualitative field research, primarily in the Northeastern United States, this chapter examines the innovative transactions that have enabled CSA and other Community Supported Enterprises (CSEs) to grow. While acknowledging that the 'Community Supported' model has not solved the challenge of providing adequate incomes for producers or attracting diverse participants, the chapter presents evidence of CSA as a vibrant system connecting producers and consumers through creative transactions.

Joycelyn K. Quansah, Cesar L. Escalante, Angela Parry‐Hanson Kunadu, Firibu Kwesi Saalia, Jinru Chen · Agriculture · Ghana (Accra)

A survey was conducted among 102 urban leafy green vegetable farmers from 12 farming areas in Accra, Ghana, to determine agricultural practices and their association with microbial safety of vegetables produced. It was observed that 70% of farmers used water from waste drains for irrigation, 99% used incompletely composted manure, 96% harvested with bare hands, and over 60% disagreed that polluted irrigation water can contaminate vegetables or make consumers sick. Vegetables cultivated by farmers with no formal education, less food safety knowledge, and those who disagreed about contaminated water causing illness were associated with higher fecal coliform and Enterococcus sp. counts.

Murtah Shannon, Kei Otsuki, Annelies Zoomers, Mayke Kaag · Urban Studies · Mozambique (Beira)

This article examines the implications of global interventionism in African cities for existing claims to urban space, particularly those of farmers, using Beira, Mozambique, as a case study. A historical-political analysis demonstrates that urban farming has been a distinct feature of Beira's urbanism amidst successive and contradictory state-land regimes. A new urban regime, formed by municipal leaders and international donors, aims to erase urban agriculture from the city through urban 'development', indicating a need for better understanding of manifold claims to urban space beyond slum urbanism.

Sam Ramsden · Voluntary Sector Review · United Kingdom

This article explored an externally funded charity-led project in a deprived area of the UK, implementing urban agriculture, community gardening, and household energy activities. The project successfully engaged marginalized people, who strongly voiced outcomes including reduced isolation, improved mental health, and increased resilience and self-reliance. Environmental outcomes were less tangible but included improvements to the local environment and reduced energy usage. However, after the funding finished, marginalized participants were vulnerable to outcomes not being sustained in the long term.

Ewa Kacprzak, Barbara Maćkiewicz, Magdalena Szczepańska · Ruch Prawniczy Ekonomiczny i Socjologiczny · Germany, Poland

This study compared legal regulations for allotment gardening in Germany and Poland. Through analysis of legal acts, field research, and structured interviews, it was found that some provisions of legal acts in both countries are not strictly adhered to by users. In Poland, unclear provisions regarding crop cultivation have led to the replacement of the farming function by recreational and residential uses.

Jennifer Engels, Sheree J. Watson, Henrietta Dulai, Kimberly Burnett, Christopher A. Wada, ‘Ano‘ilani Aga, Nathan DeMaagd, J. J. McHugh, Barbara Sumida, Leah L. Bremer · PLoS ONE · United States (O‘ahu)

A researcher-farmer collaboration on O‘ahu's Sumida watercress farm conducted a 25-year trend analysis and a year of intensive spring water sampling. Negative correlations were found between historical crop yields and increases in the Oceanic Niño Index, temperature thresholds, and pest outbreaks. Despite urbanization, on-farm water quality was very high, and microbial analyses suggested the farm provides nutrient retention services to downstream systems. The study demonstrates that challenges facing urban agricultural systems shift over time.

Michael Deflorian · Social movement studies · Global

This article examines the volatile participation of critical creatives in collective alternative everyday practices (CAEPs) like community gardens, which often involves irregular engagement and adherence to unsustainable consumer lifestyles. Drawing on Late-Modern Subject Theory, it argues that participants attempt to embody an idealized Self but fail persistently due to structural constraints and personal liberties in late-modern society. This results in "refigurations" of utopia that are bound to fail, highlighting a governance challenge in sustaining engagement.

Pauline Marsh, Suzanne Mallick, Emily J. Flies, Penelope Jones, Sue Pearson, Iain S. Koolhof, Jason Byrne, Dave Kendal · International Journal of Environmental Research and Public Health · Global

This study assessed the socio-spatial context of a proposed Campus Community Garden (CCG) at a student university accommodation site. It explored perceptions of the space and the proposed garden through interviews, focus groups, a survey with diverse university and community stakeholders, visual observations, and public life surveying. Results confirmed known problems associated with an underutilized site and identified unknown barriers, including socially disconnected stakeholders and community distrust of the university.

Tomoko Imoto, Nobutaka ISHITSUKA, Cheligeer, Kiyohide Morita · JOURNAL OF RURAL SOCIETY AND ECONOMICS · Japan

This study investigated allotment garden use among child-rearing generations in Japan, identifying preferences for "free space (play area)," "staff to answer questions," and "events." A questionnaire survey of first-grade parents revealed a high potential demand for allotment gardens, with preferences for lower fees, play areas, cultivation guidance, and events. However, an analysis using a cross-effect model found a disconnect between preferences for garden use and food preferences, as those who buy domestic products generally did not value events, indicating a "food-agriculture gap."

Fanni Bársony · Tér és Társadalom · Hungary

This study examines urban community gardens in Hungary through fieldwork and group interviews. It investigates how these gardens function as urban commons, focusing on community characteristics, resource relationships, and sharing practices. The research concludes that for urban commons, it is insufficient to focus solely on the shared resource and access conditions; the commons must be examined in relation to the operating community.

Lisa Berglund · · United States (Detroit)

This paper analyzes media coverage of informal practices like street vending, murals, and urban agriculture in Detroit's redeveloping neighborhoods. It reveals that while these practices are appropriated by developers and new, affluent arrivals as entrepreneurial and necessary for redevelopment, they are treated fundamentally differently from the informal practices of long-standing, marginalized residents, which are often condemned as illegal. This inconsistency highlights how legal frameworks are manipulated to exclude long-standing residents from the city's "renaissance."

F. Feldmann, Ute Vogler · Journal of Plant Diseases and Protection · Global

Ten key challenges for plant protection in cities were identified, each belonging to a specific field of action of Integrated Pest Management (IPM) in urban horticulture, according to Directive 2009/128/EC. These challenges include appropriate plant selection, microbiome engineering, nutrient recycling, smart digital solutions, diversification of vegetation, avoidance of pesticide side effects on beneficials, biorational efficacy assessment, effective pest diagnosis, efficient outbreak control, and holistic approaches.

Mary Njoki Mwaura, Sabina Wangia, Japheth Ododa Origa, Lee Ernest Mbatia Oliver · Journal of Agricultural Extension · Kenya (Nairobi)

This study investigated the influence of urban extension workers' socio-economic characteristics on farmer empowerment in Nairobi County, Kenya, using data from 64 extension workers. While extension workers' characteristics positively influenced the choice of extension methods, explaining 37.2% of farmer empowerment, a significant finding was that 49.9% of extension workers were unaware of adult learning principles (ALPs). The study recommends training extension workers in ALPs and ICT techniques to improve extension methods.

Oso Adeola Abiola · Zenodo (CERN European Organization for Nuclear Research) · South Africa

This review discusses vegetable production in South Africa, focusing on the impacts of root-knot nematodes (Meloidogyne species) on small-scale farming communities. The review highlights that these nematodes are a primary pest, causing delayed crop maturity, reduced yields, poor quality produce, and escalating production costs. This leads to substantial income losses for farmers and the abandonment of community gardens, intensifying challenges for vegetable production and food security.

Lexi Earl, Pat Thomson · · United Kingdom (midlands in England)

This chapter examines a school garden with farm elements at a primary school in a deprived market town in the midlands of England, established as part of an 'eco-school' initiative driven by the former head teacher. The garden included various spaces like a farm, raised beds, a pond, and a herb garden, used for science learning and natural exploration. However, the study notes that the impetus for outdoor learning diminished after the initiating head teacher departed, as school priorities shifted due to other pressures.

Maximilian Manderscheid, Valentin Fiala, Bernhard Freyer · Zenodo (CERN European Organization for Nuclear Research) · Global

This report D4.3 describes the status quo analysis and documentation of Edible City Solutions (ECS). Over 300 ECS were identified in Berlin and Montevideo, and online research was conducted in Carthage and Lomé, after which a total of 84 ECS were documented in detail using a mixed-method approach (online survey, interviews, workshops, etc.). Most documented ECS take the form of urban gardening and focus on social benefits like providing education and fostering social cohesion, but the report does not detail specific challenges or limitations regarding governance.

Justine Lindemann · New York University Press eBooks · United States (Cleveland)

This chapter explores how gentrification in Cleveland, Ohio, impacts Black urban farmers' and gardeners' access to land in disinvested neighborhoods. It examines the ancillary effects of development on alternative land reuse efforts. The study highlights that despite a seemingly endless supply of vacant lots, gentrification negatively affects land access for these communities.

Ada Górna, Krzysztof Górny · Miscellanea Geographica · Cuba

An exploratory, classification-based study combining fieldwork with satellite and aerial imagery analysis characterized urban agriculture across the built-up areas of Havana, Cuba. It found urban gardens distributed unevenly across the city, concentrated in lower-density districts where land was intentionally left between buildings by modernist planners, with organopónico (organoponics) as the most common production technique — but found that the material commonly used to build the bordering walls of these plots is asbestos, posing a significant health threat to both producers and consumers.

Charlotte Glennie · New York University Press eBooks · United States

This chapter traces the history of Seattle's P-Patch community garden program, which resident-activists have kept insulated from development pressure by advocating for it at critical moments. Advocates pursued a pro-growth strategy, framing the gardens as good for a growing city, which fed Seattle's image as green and livable and helped attract high-income residents and raise property values; while the gardens themselves remain secure, low-income and other vulnerable residents are being displaced by this green gentrification.

Pamela Arnette Broom, Yuki Kato · New York University Press eBooks · United States

This chapter examines the gentrification of foodways in post-Katrina New Orleans, combining the author's own experience as a long-term urban gardener with grower interviews. It argues that the emerging narrative presenting urban agriculture as a new idea obscures the city's long-standing tradition of local food production and procurement, and that the new geographic notion of local tends to dissociate from the social and cultural dimensions of preexisting folk foodways; it concludes that the popularity of urban agriculture among newcomers, though well-intended, had the adverse effect of discouraging many long-term residents from engaging with urban agriculture and from opportunities such as entrepreneurship, community health and urban sustainability.

Zach Mortice · Landscape architecture · Canada

This article covers landscape architect Alexander Cassini's (ASLA) involvement with the Carré Casgrain community garden in the Little Italy neighborhood of Montreal, Canada. The city and Le Carré et sa Ruelle began a process of establishing the site as a real estate reserve, transferring ownership to the city with management handed to the community members who had rehabilitated the land, but the piece reports that the battle over the vacant lot left the community garden in ruins.
