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.

This study investigated the drivers of de-agrarianization in post-socialist cities, using Brno, Czech Republic, as a case study through qualitative interviews. It found procedural issues in preserving architectural heritage during the redevelopment of a former Cistercian monastery site, often resulting in only fragments being preserved. The research also demonstrated a decline in the use of urban agricultural properties, which are rapidly transformed into new urban environments under intense urbanization pressures.

This study investigated the interrelations between urban agriculture and local institutions in Belém-PA and Porto Alegre-RS, Brazil. In both municipalities, actions were observed that were implemented temporarily but lacked continuity. Porto Alegre showed more commercial channels derived from previously established institutional relations, while Belém presented several elements without alternative solutions for problems related to high temperatures and navigation distances.

This study investigated the needs and commercialization challenges of chinampa producers in Xochimilco, Mexico City, to assess the potential of a green label. The analysis, based on a literature review and producers' mental model analysis, found that unresolved issues like commercialization problems, consumers' unwillingness to pay fair prices, soil degradation, and poor irrigation water quality persist. These issues make it difficult for most producers to bear certification costs, indicating that implementing a green label would likely fail to deliver its intended benefits.

A multiyear transdisciplinary project in Phoenix, United States, analyzed the development of a sustainable urban food forest enterprise. The project built a coalition of supporters, secured a suitable site, codeveloped a vision and action plan, and fundraised a major start-up donation. However, research findings indicate that despite achieving success factors to some extent, an underdeveloped sustainable entrepreneurial ecosystem jeopardizes long-term success and multiplication efforts.

André Torre, Brenno Fonseca · Sociologia Ruralis · Brazil (São Paulo)

A study on the development of peri-urban agriculture in the São Paulo Metropolitan Region, Brazil, was conducted based on expert interviews, analysis of the regional daily press, and local information sites and blogs. It was found that territorial opposition between different land uses is one of the main factors preventing food production in urban and peri-urban areas. The study investigated local conflicts, their location, their link to agriculture, the consumption of agricultural soils, and the typology of opponents and supporters of this activity.

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.

Paulo Silvano Magno Fróes-Júnior, Fabrício Khoury Rebello, Marcos Antônio Souza dos Santos, Cyntia Meireles Martins, Maria Lúcia Bahia Lopes, João Paulo Borges de Loureiro · Conjecturas · Brazil (Belém)

This study interviewed 63 urban farmers in Curuçambá, Belém Metropolitan Region, Brazil, analyzing business management and entrepreneurial skills amidst urbanization and crime risks. It found that 98.41% of businesses are family-managed, but 52.38% have little management experience, with 76.19% never keeping financial records and 81.71% never seeking technical assistance. A significant 33.33% of farmers rated criminality as "very high" severity, indicating that a lack of public safety severely limits commercial performance and investment in urban agriculture.

This study investigated the role of cooperativism as an element for strengthening urban and peri-urban agriculture (AUP) in Brazil. Findings revealed that the absence of public policies and credit availability are limiting factors for AUP. Increased production and product outflow are also difficulties faced by these farmers, which could potentially be resolved through cooperation.

This paper explores how urban farming in Atlanta, Georgia, shows evidence of neoliberal shaping and retooling. Through qualitative analysis, including a case study, interviews with farmers, participant observation, and archival data collection, it examines how the city and the farm are understood from the perspective of the farmer to understand the degree to which these contestations are resisting neoliberalism. The research suggests that while urban farming can provide spaces for contestation to neoliberalism, scholars should more fully consider the hybridized nature in which urban farmers understand their work.

Kinanti Safirtri, Oekan S. Abdoellah, Budhi Gunawan, Yusep Suparman, Parikesit Parikesit · The Qualitative Report · Indonesia

A qualitative study with 27 export-scale urban farmers in Bandung Metropolitan investigated market pressures to meet international food standards. While intended to encourage environmentally friendly practices, farmers interpreted the implementation of international food standards as an administrative formality for export requirements, rather than a critical reflection on environmental problems from intensive agricultural practices. Consequently, market pressure from international food standards was found to be paradoxical and ineffective in fostering farmers' environmental responsibility.

Eugene McCann, Nathan McClintock, Christiana Miewald · Environment and Planning E Nature and Space · United States (Portland, Oregon)

This paper introduces "impermaculture," a model of urban agriculture where farmers in cities like Portland, Oregon, embrace the impermanence of their operations, viewing the potential for displacement by higher-value developments as an intended modus operandi. This approach, utilizing portable growing systems, is presented as a means of stabilizing the "sustainability fix" in neoliberal cities. The study suggests that this 'impermaculture by design' shores up and temporally rescales the sustainability fix, providing stability to urban agriculture initiatives despite their temporary nature.

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.

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.

Ferdi Gultom, Sugeng P. Harianto · Jurnal Analisa Sosiologi · Indonesia

Using dependency theory, this literature study analyzes the decline of the agricultural sector in urban Indonesia, arguing that the government's focus on industrial-sector development, mediated through a central state-satellite relationship, has drawn in the modern sector at agriculture's expense, manifested in widespread conversion of urban agricultural land. Drawing on news sources and journals and analyzing data with the Miles and Huberman model, the study finds that the urban agricultural sector is fading as farmland is increasingly converted to industry, infrastructure and settlements, and that farmer regeneration has declined due to reduced interest in becoming a farmer.

An ethnographic study using in-depth interviews and participant observation, conducted April to November 2020 with thematic analysis, examined the role of the informal food sector in food flows in Cape Town, South Africa, during the COVID-19 lockdown. The informal food sector has historically been subject to exclusionary urban policies, and lockdown regulations caused food flows through the sector to cease, resulting in job loss and increased food insecurity. The sector subsequently reshaped food flows through urban agriculture, food aid programmes and community change, though it can also hinder urban modernisation. The study concludes regulatory frameworks need to be more inclusive of the sector.

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.

This study analyzed the potential of allotment gardens (AGs) in Poland to be considered nature-based solutions (NBS), examining their use of green/blue infrastructure, problem-solving capabilities, benefits, and economic efficiency. The study identified institutional barriers, irregular distribution of benefits, and deficiencies in economic efficiency as significant obstacles. It concluded that AGs, while a type of unsophisticated NBS, have limited effectiveness.

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.

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.

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.

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.
