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.

Annelise Caetano Fraga Fernandez, Almir Cezar Baptista Filho · Cidades, comunidades e território/Cidades comunidades e territórios · Brazil

This article describes the obstacles to applying Brazil's family-farming public policy in urban settings. It shows that a set of representations associated with rural agriculture has shaped the classification criteria used by rural technical-assistance (ATER) staff, and that this in practice limits how the policy can be applied in urban areas. It states that the mobilization of social movements linked to urban agriculture, specifically in the municipality of Rio de Janeiro, led to the construction of an initiative, but the available abstract breaks off at that point.

This review maps the use of food sovereignty principles in urban and peri-urban agriculture (UPA) in Zimbabwe, addressing its potential for food security. Despite UPA being ingrained in urban households' livelihoods, institutional arrangements governing the practice remain ambivalent. The review underscores that the failure to involve all stakeholders undermines UPA, leading to heightened food insecurity and unsustainable practices.

Nathan McClintock, Christiana Miewald, Eugene McCann · · North America

This chapter explores urban agriculture (UA) as fundamentally political practices, examining its role in neoliberal governance and sustainability policy-making, and as an object of contestation. It relates UA motivations and practices to processes of urbanization and political economic restructuring. The chapter highlights that UA is a site of political contestation, arising from broader political economic shifts.

Anna Trembecka, Anita Kwartnik-Pruc · Sustainability · Poland

This study analyzed data on the number and area of allotment gardens, their distribution across Poland, and the process of regulating the legal status of land occupied by allotment gardens. The research identified the number and area of family allotment gardens in Poland, along with the range and types of claims against them. The study found that land occupied by family allotment gardens requires protection and legal status regulation, which is difficult due to various entities submitting claims to these areas because of their attractive urban locations.

Suranga Wadduwage · Journal of Land Use Science · Australia (Adelaide)

A multi-criteria spatially-explicit study in the Adelaide metropolitan area, Australia, investigated agricultural land vulnerability to urban sprawl under opposing policy directions. The study showed higher agricultural land vulnerabilities in “Business-As-Usual” and “Accelerated Economic Development” scenarios, extending into rural areas with a leap-frog effect. This confirms the need to sacrifice farmland uses to maintain land supply for urban development under these conditions.

Dona Pickard · International Journal of Sociology of Agriculture and Food · Bulgaria (Plovdiv)

This paper analyzes an urban agriculture case in Plovdiv, Bulgaria, where the municipality cleared over 2 hectares of long-tolerated allotments without involving users, despite NGOs promoting urban agriculture as a social innovation. The case exemplifies barriers hindering social innovation, particularly regarding governance, as the eviction occurred without discussion about the future of urban agriculture. This suggests a lack of civic participation and access to resources for deprived groups.

Tinashe P. Kanosvamhira · Development Southern Africa · South Africa (Cape Town)

Based on a literature review, urban agriculture and its organizational forms in Cape Town, South Africa, were explored. A lack of effective coordination of initiatives among supporting actors was suggested to be a significant pitfall in the development of urban agriculture. Furthermore, the failure of farmers to self-organize was identified as equally detrimental. Therefore, improved synergies between state and non-state actors are called for to enhance the gains of urban agriculture.

Percy Toriro · · Zimbabwe (Harare)

This chapter explores the governance of urban food production in Harare, Zimbabwe, from 1890 to the present. Evidence indicates that while the practice has gained general acceptance through shifting positions over the years, the status of producers remains uncertain. This uncertainty stems from the lack of full incorporation of urban food production into city plans by planning officials, whose values are out of sync with Harare's lived reality.

This article examines over fifty self-managed community gardens in Loisaida, New York, which form an informal network combining "affection" and "dissidence" to create "affect-dent" spaces. These gardens, established since the 1960s, reconfigure public space by opposing administration, the real-estate market, media invasion, and the appropriation of public space by the private sector. The study highlights how these spaces challenge dominant power structures and serve as a reference in contemporary architecture of the common.

肇 石原, Hajime Ishihara · Institutional Repositories DataBase (IRDB) · Japan

This paper compared urban agriculture promotion basic plans formulated by six prefectures, including Tokyo, Osaka, and Aichi, as of October 2017. The analysis revealed policy challenges concerning the scope of inheritance tax deferment, the lending and borrowing of agricultural land in urbanization promotion areas, and the participation of non-farmers in agriculture. It concluded that the national government urgently needs to address these issues, and local governments should propose systems tailored to local conditions.

This case study in Sete Lagoas, Brazil, discusses the advances and challenges of agroecological urban community gardens, which have a history of approximately 33 years. Research findings indicate that public policy enables income generation for producers, increased supply, and food security in the region. However, the study highlights the need for greater support to address producers' limited technical knowledge and the importance of more supportive interpersonal relationships.

This study used a consensus-driven process to identify central issues impeding the sustained success of school gardens. It outlined practical, logistical, and institutional barriers that need to be addressed to ensure their success in supplementing education.

Marttem Costa de Santana, Everardo de Sousa Luz, Maurício Ribeiro da Silva, Maclóvia Corrêa da Silva, Eloy Fassi Casagrande · Sociedade e Território · Brazil

This qualitative field study in two cities in Piauí, Brazil, evaluated whether working conditions of urban and peri-urban agricultural producers contribute to food production. It concluded that public authorities' participation is necessary to address failures in the small-scale agricultural production system and improve working conditions for urban horticulturists.

Paloma Gonzalez de Linares · International Journal of Design & Nature and Ecodynamics · Hungary (Budapest)

This paper aimed to assess factors contributing to more successful integration of urban agriculture in some cities and to introduce agro-ecology practices in public green spaces and community gardens through landscape assessment and map-based comparison. A key problem identified was the lack of motivation among planners to integrate urban agriculture into urban plans, preventing these green structures from becoming part of the city's landscape and dynamics. The sustainability of food systems was concluded to depend on the city's planning strategy and governance policies.

Piyapong Boossabong · Amsterdam University Press eBooks · Thailand (Bangkok)

In Bangkok, most vegetables consumed in the city are transported from remote rural areas and contaminated with chemicals. Governmental policies have failed to control chemical use, while monopolistic food corporations constrain the sustainability of local food systems. This chapter highlights the collaboration of urban farming networks in Bangkok that aim to produce alternative food sources and create alternative markets, arguing that these networks can construct alternative urban spaces for social action.

Sécou Omar Diédhiou, Oumar Sy, Christine Margétic · Espace populations sociétés · Senegal (Ziguinchor)

A study in Ziguinchor, Senegal, surveyed 248 farmers and 130 vegetable vendors in 2016 and 2017 to examine the role of urban agriculture. Urban expansion has led to shrinking agricultural land and land-use conflicts, while increasing food demand. Women play a central role from production to commercialization, farming in multiple locations for self-consumption and income, but the sustainability of these practices requires integration into proactive urban development policies.

A study on the use and value of green school grounds in developing countries was conducted across five schools in Podujevo, Kosovo. The findings revealed that the potential of green school grounds in most studied cases has not been utilized. Opportunities provided by the municipality and environmental NGOs are insufficient, suggesting a need to rethink the design and use of green school grounds in developing countries.

Michelle Marie Proctor · · United States (Detroit)

Urban agriculture programs in Detroit have seen many urban farms begin to include animals, sparking policy and ethical debates. Supporters claim animals accelerate land remediation, fertilize and aerate soil, and improve petroleum-polluted soils. However, opponents point to problems such as botched slaughters and lack of animal welfare oversight, arguing that backyard animal husbandry should be regulated in the best interests of the community and animal welfare.

Sugandhi del Canto, Rachel Engler‐Stringer · Policy Press eBooks · Global

Restrictive covenants, a corporate real estate practice, are identified as a significant barrier to establishing new food stores in older neighborhoods globally. These covenants place conditions on land use, such as prohibiting food sales or grocery store development, making it harder to address existing nutrition deserts. Government support is needed to limit these covenants and develop alternative food channels, including urban agriculture.

A spatial analysis and socio-economic survey were conducted on land occupation, land conflicts, and their management in the Funa Valley in Kinshasa. The findings revealed a strong evolution of anthropogenic presence in the valley and identified multiple land conflicts, including illegal sales of parcels by customary chiefs and illegal occupation of agricultural land by non-market gardeners. The management of these conflicts is often referred to the district chief and the justice ministry.
