This article discusses Polish urban allotment gardens (UAGs) as an alternative urban development framework, "Slow City." It notes that increasing problems of soil pollution, abandoned gardens, informal housing, and limitation of access to UAG green areas for other inhabitants reinforce the pressure to reduce the number of UAGs.

This study analyzed food security in two medium-sized cities in Western Mexico using secondary data and field research. It found that while these highly globalized cities had a low degree of food security, extensive domestic backyard agricultural activities significantly raised family-level food security. A critical finding is that this potential for urban food security is not valued by governmental institutions.

A study explored and compared international standards of prevailing organizations and their functioning among 261 urban gardeners in two cities in Benin. It found that a vast majority of urban gardeners are members of a cooperation. However, their membership is largely titular because gardeners mostly behave semi-autonomously, and few decisions are taken collectively. The obvious economic advantages of leveraging bargaining power, reducing transaction costs, and increasing possibilities for loans are seriously underutilized.

The Incredible Edible Todmorden (IET) movement in Todmorden, UK, was investigated using a qualitative approach. The scheme was found to have an overwhelmingly positive impact on the town, providing social, environmental, and economic benefits and contributing to a more just food movement through its "free for all" philosophy. However, negative aspects were also highlighted, including maintenance issues and a lack of perceived inclusivity in some parts.

This study investigated the position of urban agriculture within development policies and legislation for urban and regional planning. Through legal analysis of legislation from supranational to municipal levels, it was shown that urban agriculture can be a tool in city planning to reduce vacant lots and buildings not fulfilling their social function. However, the research revealed that despite a diverse range of legislation for urban agriculture development, these laws are not fully interconnected and often operate as parallel initiatives.

Ashenafi Tilahun Hailie · IGI Global eBooks · Global

This chapter assessed the benefits of urban agriculture in a study area, using qualitative and quantitative analysis aligned with a sustainable livelihood framework. Findings indicated that urban agriculture is sustained by sex indiscrimination, migrant dominancy, poor educational status, and agricultural background. While assets like land access and fertile soil were promising, skills, knowledge transfer, labor ability, and good health were found insufficient. Identified vulnerabilities included population explosion, absence of good governance, frequent natural calamities, land tenure insecurity, and seasonality of prices.

A global study characterized nature-based adult day services (ADSs) for people with dementia (PwD) in urban areas and identified challenges. Interviews with 17 ADS providers revealed five types of services: social entrepreneurs, nursing homes, social care organizations, community gardens by citizens, and hybrid initiatives. General challenges included the availability of green urban spaces and acquiring funding. Specific challenges varied by type, including a lack of commitment among nursing staff in nursing homes, difficulty finding knowledgeable volunteers for community gardens, and work culture differences in hybrid models.

The UFISAMO project analyzed urban agriculture (UA) in Maputo and Cape Town. In Maputo, UA is the main income source for about 5% of the population, though it often does not cover monthly food costs, and a major challenge is the uncontrolled application of pesticides due to mono-cropping. In Cape Town's townships, UA plays a negligible role in income and food security due to small plots, sandy soils, water stress, and weak market links.

Jean-Christophe Levassor · DOAJ (DOAJ: Directory of Open Access Journals) · France

This study addresses social divisions in Le Pile, east Roubaix, France, where over 40% of residents live below the poverty line. It states that without proactive policies, social divisions will worsen, and initiatives like urban farming and zero waste will only have a limited effect beyond a small circle of insiders. La Condition Publique aims to recreate ties among various actors to support urban renovation and foster resilience in this deprived neighborhood.

Riska Rahma Arriani, Mardwi Rahdriawan · Teknik PWK (Perencanaan Wilayah Kota) · Indonesia (Jakarta)

A qualitative study using purposive sampling investigated the reasons for decreasing community participation in the government-initiated Urban Farming Program at Rusun Marunda, Jakarta, Indonesia. The program, which started with 50 farmers in 2014, saw participation drop to only 5 farmers by 2019. The study found that obstacles in farming demotivated farmers, leading to a decline in participation, particularly among those with economic-egoism motivations.

Joshua Sbicca · · United States (Colorado)

This study investigated the potential for urban agriculture to drive green gentrification, using Denver, Colorado, as a case study. Urban agriculture was shown to drive gentrification and act as a force for displacement, even when advocates are aware of its exclusionary potential for urban farmers and residents. The research argues that political economy and cultural forces create neighborhood disinvestment and economic marginalization, and urban agriculture contributes to green gentrification through a process of revalorization that exploits rent gaps.

Chiara Certomà, Chiara Tornaghi · Ghent University Academic Bibliography (Ghent University) · Global

This book is a collection of chapters unpacking the forms, functioning, and meanings of urban gardening in the context of the neoliberal transformation of cities. It offers an overview of diverse claims in the micro-politics of garden activism and discusses how these projects are fraught with social solidarities and divisions, empowerment and learning processes, conflicts and negotiations. The collection aims to contribute to a critical discussion of the “politics of urban space” and enrich the emerging debate on radical, critical, and political gardening.

Setyo Parsudi · Berkala Ilmiah AGRIDEVINA · Indonesia (Surabaya)

This study in Surabaya, Indonesia, aimed to identify urban farming models, community motivations, and obstacles faced in implementing urban agriculture. The study found that the most common urban farming models were hydroponics, followed by verticulture, fisheries, and rooftop gardens. Community motivations primarily included increasing income, utilizing empty land, pursuing farming hobbies, and using green open spaces. The main obstacles faced by the community were plant pests, lack of capital for development, extreme weather, and insufficient experience and knowledge in urban agriculture.

Martin Jayo, Eduardo de Lima Caldas · kult-ur revista interdisciplinària sobre la cultura de la ciutat · Brazil (São Paulo)

A study in São Paulo, Brazil, examined recent forms of appropriation of the urban agriculture agenda, using a historical analysis of urban agriculture practices by Caldas and Jayo (2019). It was observed that traditional urban agriculture discourses have been captured by new actors, including parts of the public sector opportunistically appropriating the theme and the real estate market promoting an imitation of urban agriculture as a marketing tool.

Lemi Gonfa · · Africa

This paper reviewed the role of urban agriculture in socio-economic and environmental sustainability in Africa, drawing on theoretical and empirical literature. While urban agriculture is recognized for job creation, improved diet, and environmental benefits like urban greenery and biodiversity, challenges such as difficult land access, lack of experience, financial support, training, and credit facilities, as well as low land productivity, animal grazing, and theft, were identified. These factors present potential negative externalities and hinder the development of urban agriculture.

Sofia Nikolaidou · Manchester University Press eBooks · Europe

This chapter examines new forms of urban gardening, often involving informal and temporary reuse of vacant land, and their impact on urban green space governance and planning practices. Using examples from Greece and Switzerland, it highlights differences and similarities in practices, social and institutional contexts, and collaborative governance patterns. The study calls attention to the critical role of the temporary nature of these initiatives, which affects new configurations of urban green areas and public space, and related planning practices.

A repeated cluster randomized controlled trial in 30 schools with 1,760 schoolchildren (8–14 years old) in Burkina Faso evaluated the impact of school vegetable gardens combined with nutrition education. The study found a small but significant increase in knowledge of sustainable agriculture (+5.0%) and food/nutrition (+6.6%). However, there was no significant increase in other outcome indicators, including fruit and vegetable consumption.

Candis M. Hunter, Dana Williamson, Melanie Pearson, Eri Saikawa, Matthew O. Gribble, Michelle C. Kegler · Local Environment · United States (Atlanta)

This study used five focus groups with Atlanta community garden leaders to investigate perspectives on composting, hygiene, and mulching, which are practices to reduce exposure to soil contaminants. Gardeners cited a need for more funding, volunteers, and training. A primary barrier to composting and mulching was concern about contamination of source materials, and participants did not directly link these practices to reducing soil contaminant exposure. Hygiene challenges included concerns about beneficial bacteria, inadequate water access, and limited supplies.

Neal Chalofsky · Advances in Developing Human Resources · Global

This paper reflects on the 35-year growth experience of the TPSS Food Cooperative, examining challenges faced by social entrepreneurship. It notes that individuals with vision often lack social movement learning (SML) and human resource development/organization development (HRD/OD) skills to grow and direct organizations, leading to their demise or a shift towards business over social aspects. The paper argues that lessons from the 1970s food cooperative movement can benefit contemporary social entrepreneurships.

Lucy Rose Wright, Ross Fraser Young · Manchester University Press eBooks · Global

This chapter introduces the concept of political gardening, contextualizing its rise within neoliberal processes and academic interest in urban gardening. It conflates political gardening with injustice, drawing on Rawls' theory of social justice. The chapter uses case study examples to define political gardening as a six-stage iterative process that participants undergo to address injustices and become engaged, democratized citizens.

This landscaping study, conducted from 2017-2018, investigated eight school gardens in Mansoura City and Talkha District, Dakahlia Governorate, Egypt. The study revealed that most school gardens contained toxic plants like weeds and cacti, and that utilized areas were not correctly used with poor maintenance. Roof gardens and improved irrigation systems were suggested.

Joeli Silva de Souza, Ryzia de Cássia Vieira Cardoso, Lídice Almeida Arlego PARAGUASSÚ, Sidione Ferreira dos Santos · Revista de Nutrição · Brazil (Salvador-Bahia)

A cross-sectional exploratory study in Salvador-Bahia characterized community gardens, with five out of seven gardens participating and data collected from 13 horticulturists. 80.0% of gardens lacked land legalization, 100.0% operated without technical support, and 60.0% had no social organization. Major difficulties included lack of funding, volunteers, and water use restrictions, indicating insufficient policies limited technical support and financing.

Tinashe P. Kanosvamhira, Daniel Tevera · South African Geographical Journal · South Africa (Cape Town)

A mixed-methods study in Mitchells Plain, Cape Town, examined the linkages between urban gardeners and supporting actors using questionnaires and in-depth interviews. Findings indicate that the nature and strength of these linkages are critical for urban gardening success. However, there is minimal cooperation among non-state actors in the area.

Marco Picone, Filippo Schilleci · Nova Science Publishers (Nova Science Publishers, Inc.) · Italy

A critical essay examining an urban-garden participatory process underway as part of Palermo, Italy's "Laboratorio Palermo città educativa," launched by the municipality in 2015 to convert abandoned or degraded public green areas into urban gardens for educational activities across all ages, in the name of neighborhood community reappropriation. The paper argues that in a context of austerity urbanism, it is easy for the municipality to exploit the absence of public investment to mobilize active citizens as protagonists of urban change, and that the idea of creating urban community gardens—like other recent slogans such as smart cities and creative cities—tends to become a universally praised, virtuous development model without scrutiny. It further notes that the lack of an effective regulation governing the use of public green spaces in the city continues to create obstacles to the solutions proposed by the thematic working table. The author concludes that field-based qualitative research is still needed to determine whether these reappropriation processes conceal neoliberal dynamics that delegate a false decision-making power to citizens while using them to fill current political vacuums.

Shawna Holmes · Canadian Food Studies / La Revue canadienne des études sur l alimentation · Canada

Interviews with school food environment staff across Canada examined how provincial nutrition regulation changes affected food procurement. While the regulations opened opportunities to improve nutrient content and involve local producers or school gardens, some schools struggled to procure nutritionally compliant food because of higher costs of transporting produce to rural, remote or northern communities and logistical problems such as spoilage. Regulations improved food environments in some schools, but others still require more support.
