This review analyzed opportunities and constraints for creating edible cities and accessing wholesome functional foods sustainably. While urban food production methods like controlled-environment farms and home gardens exist, significant constraints include pollution, a lack of government support, and economic challenges for urban farms. These issues must be resolved for edible cities to become widespread.

Mareike Schwarz · Street Art & Urban Creativity · Global

This paper analyzes the intersection of urban art and community gardens to explore whether commons can emerge from this collaboration. Through a comparative study of two community garden projects in Berlin and Dakar, the research examines the impact of funding structures, accessibility, artistic concepts, and design on commoning. Findings reveal that the two projects differ significantly in their development context and underlying structures, affecting their ability to function as commons. Furthermore, the paper argues that the dependency of artistic involvement on third-party funding contradicts the principles of commoning.

Juan Camilo Ochoa Céspedes · Entorno Geográfico · Colombia (Medellín)

This paper critically analyzes peri-urban and peri-urban agriculture, addressing problems of territorial tension resulting from the accelerated expansion of real estate into peri-urban areas due to low urban land availability. The discussion questions the economic, environmental, and social risks of this expansion, highlighting tensions and resistance. The paper illustrates these issues with examples from the peri-urban area of Medellín and its metropolitan area.

Following the PRISMA protocol, a 2023 systematic review evaluated 26 studies on the interplay between urban agriculture (UA) and sustainability surveyed on Web of Science. While UA is increasingly recognized as an action to promote urban sustainability and inform public health policy for urban populations, the review confirms that its implementation still presents challenges in countries across both the Global North and Global South. The review identified numerous key challenges to UA adoption, including air and soil contamination, availability of green areas, layout of urban infrastructure, and food distribution, among others. Given the many socio-economic and environmental contextual factors involved — especially when comparing Global North and Global South realities — the review concludes there is a need to develop a model adaptable to these different contexts. It further concludes that the concept of sustainability lacks a universal understanding, and that one of the most important remaining gaps is addressing social issues in relation to environmental ones.

Andrea Fantini · Agroecology and Sustainable Food Systems · Global

This paper analyzes the functions of urban and peri-urban agriculture (UPA) as a strategy for sustainable and resilient urban food systems and for coping with global emergencies. It identifies various functions of UPA and how they connect, but also discusses obstacles to its large-scale implementation. The paper highlights that despite its potential, significant barriers hinder UPA's widespread adoption.

Amy Lawton, Nicky Morrison · Land Use Policy · Australia (Greater Western Sydney)

This study examines the drivers of peri-urban agricultural land loss in Greater Western Sydney, Australia, with a focus on the role of government agencies. It found that competing housing priorities and private market interests continue to take precedence over protecting agricultural land. The research indicates that this trend will persist unless the current pro-urbanization narrative and associated political priorities are altered.

Betty Mntambo · Huria Journal of the Open University of Tanzania · Tanzania (Morogoro Municipality)

This study examined land tenure security in urban agriculture among 69 male and female vegetable farmers in Morogoro Municipality, Tanzania, using snowball sampling and a cross-sectional design. Findings revealed that farmers access land informally by renting from legal landowners, with social relationships determining tenure security. Land tenure insecurity negatively affects vegetable cultivation and generates uncertainty and animosity between farmers and landlords.

Jelena Živanović Miljković, Vesna Popović, Aleksandra Gajić · Land · Serbia (Novi Sad)

A study conducted in Futog, Novi Sad, Serbia, investigated land take (LT) processes and challenges for urban agriculture, focusing on the role and implications of land use planning. Quantifying LT for 2000–2018 using CORINE Land Cover and Urban Atlas datasets revealed that a significant portion of agricultural land in Futog, registered as a Geographical Indication (GI) for Futog cabbage, was planned for conversion into construction land. The study concluded that current land use planning in Serbia is inadequate to ensure the protection of either urban agriculture or GIs.

Elias Danyi Kuusaana, Isaac Ayurienga, Joyce A. Eledi Kuusaana, Joseph Kwaku Kidido, Ibrahim Abu Abdulai · Frontiers in Sustainable Food Systems · Ghana (Bolgatanga)

A study in Bolgatanga Township, Ghana, used field surveys, key informant interviews, and GIS mapping to examine urban agricultural practices. It found that agricultural lands significantly decreased in size and contiguity since 1996 due to urban sprawl, forcing farmers to use segregated plots and undeveloped residential areas which are easily lost to development. The study concluded that urbanization exacerbates food production challenges without policies to protect agricultural lands.

Norma Wong, Marte C. W. Solheim · Edward Elgar Publishing eBooks · Norway

This case study details Tugushan Alp's entrepreneurial journey in Norway, where he pioneered hydroponic lettuce production in a bomb shelter. Alp faced multiple hurdles, including battling regulatory bodies for a legal premise. Despite these challenges, he achieved success and recognition for his innovative urban farming method.

Susan Anne Mansel Fitzgerald · · Cuba

This chapter reviews various perspectives on urban agriculture in Havana, Cuba, focusing on farm types, food access, and cultural expressions. It highlights that research also addresses the hierarchies and power struggles surrounding urban agriculture sites and their integration into land-management systems. The study advocates for understanding the rhythms of everyday life to deepen insights into these sites.

Shawn Bodden · City · Hungary (Budapest)

This essay reflected on the everyday political work of community projects to open up space for new possibilities of living with difference within hostile political environments, drawing on Doreen Massey's ideas of space. Through the case of the Auróra community center in Budapest, Hungary, and its members' community garden project, it examined the mundane and local techniques community groups use to construct better possible futures. The analysis suggested the importance of analyzing the situated and ongoing "terms of engagement" through which people open up, or close down, better possible spaces and ways of living with difference.

Aisling Bailey, Jonathan Kingsley · Land · Australia (Melbourne)

This qualitative study explored perceptions of benefits and challenges in six urban community and allotment gardens in Melbourne, Australia, through semi-structured interviews with 23 participants. Findings identified perceived benefits and demographic patterns, but also highlighted challenges to participation due to insecurity around ongoing land access. The gardens were perceived to contribute to social and environmental wellbeing.

Ana Zazo Moratalla, Alejandro Orellana-McBride, Claudia Cerda-Inostroza · · Chile

A study investigated how Chilean urban planning has conceived productive agriculture within urban limits, analyzing the evolution of territorial planning instruments in five Chilean cases. While agriculture was once conceived as an urban use, changes in Chilean legislation have led to this activity being conceived as transitory and in fallow, inevitably transforming into other more profitable urban uses.

Abdulaziz I. Almulhim, Patrick Brandful Cobbinah · International Journal of Sustainable Development & World Ecology · Saudi Arabia

This article reviews literature on urbanization and its implications for the urban environment in Global South cities, discussing eight implications of the urbanization-environmental conundrum with cases from Saudi Arabian cities. Findings indicate that the sustainable development agenda in Saudi Arabian cities is skewed towards socio-economic development with limited focus on environmental issues. This situation is threatening the sustainability of rapidly urbanizing cities.

Giulia Caterina Verga, Ahmed Z. Khan · Frontiers in Built Environment · Belgium (Brussels)

This study examined spatial factors fostering or hampering the embedding of urban circularity practices (UCPs) in the Brussels Capital Region (BCR) through a literature review and case-study research. It showed that access to spaces and land emerges as one of the most recurrent barriers to embedding UCPs. Beyond real estate prices, frictions in political agendas where the need for housing, productive spaces, urban agriculture land, and green-blue infrastructures compete for the same limited space also contribute to this issue.

Gordon Prain, Dávid Simon, Jess Halliday, Pay Drechsel · Frontiers in Sustainable Food Systems · Global South

Urban and peri-urban agriculture (UPA) in the Global South faces challenges such as limited recognition, land conversion, and water pollution, which threaten its potential for urban resilience. Innovations in urban governance are required to integrate food systems into urban planning through food mapping and multisectoral platforms.

Demoundou Namodji, Ndoutorlengar Medard · International Journal of Humanities Social Sciences and Education · Chad

This article notes that while urban agriculture is protected and encouraged by governments in developed countries like Japan, in Africa, urban farmers often face repressive measures from urban administrators or planners. Despite its role as a safety valve for low-income households, urban agriculture in Africa is subject to these restrictive governmental actions.

Nicola C. Thomas, Anders Blok · Nature and Culture · Denmark (Copenhagen)

This study analyzes the social and political conditions of urban allotment gardens in Copenhagen, which are specially protected as valuable urban nature. It finds that asymmetric civic-public compromises, while enabling protection, result in new material conflicts between civic and municipal actors. These conflicts are linked to unresolved competing visions of civic, green, and market sustainability in urban development.

Amine Mseddi, Mariann Simon · European Journal of Architecture and Urban Planning · Hungary (Budapest)

This paper analyzes four community gardens on vacant inner-city plots in Budapest, Hungary, to understand their challenges and opportunities. It found that these gardens face significant obstacles including temporary status, changing political circumstances, and varying local population attitudes. Despite these challenges, NGOs and local communities play a crucial role in sustaining these projects and raising awareness.

Pastory Salvatory Thomas, Wilbard Kombe, Aldo Lupala · International Journal of Social Science Research and Review · Tanzania

In-depth interviews with 60 purposefully selected respondents in the Daraja Mbili and Lemala wards of Arusha City, Tanzania, examined how diverse stakeholder perceptions of urban agriculture affect its governance. Farmers and agricultural officers viewed urban agriculture positively because their livelihoods and professional interests were tied to it, while urban planners and environmental officers were skeptical, citing a lack of evidence for its value, and implementation and enforcement of related policies and bylaws had not succeeded. Farming in environmentally sensitive areas violated bylaws, yet encroachment by farmers with no alternative land continued. The study concludes that urban agriculture cannot be effectively governed, even where policy and bylaws exist, as long as the actors involved perceive it negatively.

Bárbara Corneli Colombatto · enREDando · Argentina

Built around interviews with huerteros (urban gardeners), this piece presents both the achievements and the limits of Rosario's urban agriculture: 7 Park Gardens and 6 group gardens involving over 250 people, 25 hectares producing 2,500 tonnes a year, and a $250,000 international prize won in 2021. It also documents organizational fragmentation among gardeners, a lack of secure land-loan agreements (comodatos), the absence of sustained public investment matching the programme's international recognition, and unresolved conflicts with neighbors that the municipality does not intervene in. It cites a regional statistic that only 18% of farms in Latin America and the Caribbean are run by women.

Chethika Gunasiri Wadumestrige Dona, Geetha Mohan, Kensuke Fukushi · Sustainability · Global

This systematic literature review analyzed 54 articles on urban agriculture, examining socio-economic context, agriculture models, opportunities, and challenges. The review found that academic literature favors community gardens in developed countries and gives comparatively less attention to identifying challenges, benefit groups, and government support for urban agriculture.

Victoria Schoen, Chris Blythe, Silvio Caputo, Runrid Fox-Kämper, Kathrin Specht, Agnès Fargue‐Lelièvre, Nevin Cohen, Lidia Poniży, Konstancja Fedeńczak · Frontiers in Sustainable Food Systems · Global North

This 2021 paper, based on data collected in summer 2020 from five Global North countries (France, Germany, Poland, UK, USA), examined the effects of COVID-19 on urban farms and gardens. The pandemic presented multiple challenges, including loss of support services, lost income, and reduced output due to labor supply issues. It also created opportunities like new local markets and increased community cohesion, demonstrating how gardens adapted to become more resilient.

Christina Ergas · · Cuba

This chapter examines Cuba's urban agricultural food production, which developed through top-down government initiatives that later decentralized and subsidized local efforts in response to resource scarcity. While Cuban urban farmworkers' cooperatives enable local residents to sell produce at low costs, the program still faces social environmental stumbling blocks despite its successes in achieving high human development with a small ecological footprint.
