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.

Gabriela de Azevedo Marques, Iara Rafaela Gomes · Boletim Goiano de Geografia · Brazil

This empirical study analyzed the socio-spatial development of Urban and Peri-urban Agriculture (AUP) in Fortaleza, Ceará, Brazil, examining both spontaneous agricultural activities and municipal institutional actions. While AUP holds significant relevance in the city, particularly in peripheral areas, governmental initiatives were found to be sporadic and discontinuous, lacking a broader institutional agenda. The study concluded that despite recent municipal efforts, legal and institutional support for AUP remains weak, leading to the rapid disappearance of productive spaces and indicating that institutional actions have not effectively fostered the socio-spatial development of spontaneous initiatives.

Elly Rasmikayati, Anton Eisa Putra, Bobby Rachmat Saefudin · MIMBAR AGRIBISNIS Jurnal Pemikiran Masyarakat Ilmiah Berwawasan Agribisnis · Indonesia (Bandung City)

This study used descriptive statistics to examine urban farming-based TOGA plant cultivation activities and their obstacles in Rancabolang Village, Bandung City. The program has not run optimally, with cultivation activities not reaching the production stage for economic use, as most harvests are only for PKK group members and harvesting is not routine. Key obstacles include limited land and seed needs for cultivation, unscheduled harvesting, small production for marketing, and low member participation and irregular meetings for organization.

Sònia Callau-Berenguer, Anna Roca-Torrent, Josep Montasell-Dorda, Sandra Ricart · Investigaciones Geográficas · Spain (Barcelona)

This study analyzed the food system behavior in the Barcelona Metropolitan Region, Spain, during the initial stage of the Covid-19 pandemic (March-May 2020). Semi-structured interviews with 11 peri-urban entities and institutions revealed shortcomings in the operation and logistics of the metropolitan food system. Findings also indicated complicity between local producers and urban consumers, the role of peri-urban agricultural areas in food supply, and a need for cooperation among food system agents.

Yalew Mamo · European Journal of Business and Management · Ethiopia (Dire Dawa)

This cross-sectional descriptive study examined marketing challenges and opportunities for 226 micro and small enterprises, including urban agriculture, in Dire Dawa City, Ethiopia. Regression analysis found that product, price, and place significantly affected sales turnover, but promotion had an insignificant effect. Major challenges included a lack of coordination among government offices and insufficient commitment from enterprise owners.

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.

Irene Håkansson · Local Environment · United Kingdom (London)

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.

Pastory Salvatory Thomas, Wilbard Kombe, Aldo Lupala · Current Urban Studies · Tanzania (Arusha)

This study examined factors characterizing changes in the nature and value of urban agriculture in Arusha City, Tanzania, a rapidly urbanizing city, through in-depth interviews with 60 respondents in Daraja Mbili and Lemala wards. Findings revealed that limited access to ideal urban agriculture areas leads some farmers to acquire small plots in unlawful areas, restricting livestock numbers and crop types, and reducing their ability to meet food needs. While uncontrolled agricultural practices accelerate environmental degradation and pollution, they also support the livelihoods of needy farmers; however, the study concluded that urban agriculture cannot thrive without adequate access to agricultural land and a strong institutional framework.

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.

Sandra Patricia Montenegro Gómez, Yulian Adalberto Sepúlveda Casadiego · Universidad Nacional Abierta y a Distancia eBooks · Colombia

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.

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.

Sandra Schwindenhammer, Denise Gonglach · Politics and Governance · Germany

This qualitative and participatory case study in Germany examined the governance implications of an emerging technology in urban agriculture that connects wastewater treatment and agricultural production for urban hydroponics. The analysis found that while this technology has the potential to facilitate SDG implementation, it simultaneously creates new sector interlinkages between water and food, leading to policy demands that necessitate more integrated policymaking.

Meredith Gaglio · · United States

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.

Nhung Pham Thi, Martin Kappas, Heiko Faust · Sustainability · Vietnam

This study in Huong Thuy Town, Vietnam, examined the impacts of agricultural land acquisition for urbanization (ALAFU) on 50 affected households. It found that rice cultivation and animal breeding sharply declined, while potted flower plantation grew, becoming the main income for 34% of households. However, all agricultural activities faced challenges due to shortcomings in agricultural land allocation and development plans.

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.

Benjamin Selwyn · The Journal of Peasant Studies · Global

This article argues that a Green New Deal (GND) for agriculture must actively combat environmental degradation, social inequality, and labor exploitation, rather than merely aiming to restart capitalist economies. It identifies key areas for discussion and political action, including the reorientation of state subsidies, workers' rights, agrarian reform, the decommodification of food, agroecology, urban agriculture, new technologies, and rewilding.

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.

Mariana Portilho, Camila Rodrigues, Annelise Caetano Fraga Fernandez · Cidades, comunidades e território/Cidades comunidades e territórios · Brazil (Rio de Janeiro)

This study describes the formation of Arranjo Local da Penha, a community network created in 2016 in Rio de Janeiro's Penha favela complex, focused on urban agriculture and led by women. Through fieldwork and participant observation, the study analyzed themes of women and agroecology, health, and healthy eating. The network promoted women's empowerment and access to healthy food, but faced limits in the mobilization and development of urban agriculture.

Boglarka Z. Gulyas, Jill L. Edmondson · Sustainability · Global North

A systematic review of literature on urban agriculture (UA) in the Global North identified factors determining its success in enhancing city resilience and challenges limiting it. UA's success in increasing city resilience was defined as dependent on five factors: institutional and public support, a sufficient knowledge base, communication and collaboration among actors, and resourcefulness in efficient space and resource use. However, comprehensive assessments of UA's potential are still lacking, suggesting challenges in its effective implementation.

ELIZABETE CRISTINA RIBEIRO SILVA JARDIM · Editora Realize eBooks · Brazil

This research analyzed Brazilian school garden experiences across three document sets, identifying procedures and resources incongruent with stated counter-hegemonic objectives. The study found structural inadequacies for the school space and omissions regarding the protection and safety of farmers and students during activities. It recommends adjustments to location, spatial organization, and material resources for school gardens to ensure the health of food producers.

Sarah E. Coffey, John F. Munsell, Rico Hübner, Curtis R. Friedel · Urban Agriculture & Regional Food Systems · United States (Virginia)

A survey of 68 mayors (39% response rate) in Virginia, US, from communities under 25,000 population, investigated public food forest initiatives. Mayors identified long-term maintenance as the greatest barrier and noted that 78% of municipalities lack land use codes for food-producing trees and shrubs. While nearly 70% reported some public land food production, only one-fifth included food-producing trees. Mayors emphasized sociocultural programs and education over food access as the most compelling aspect.
