This ethnographic fieldwork, conducted across three community-led urban food forest sites in Naarm/Melbourne, examined the everyday labors, relations, and tensions involved in caring for urban food-producing trees. The study found that participants grapple with significant tensions, particularly in open-access sites lacking fences, gates, or formal membership, highlighting the evolving and imperfect nature of commoning practices rather than a fixed ideal.

A qualitative case study in Dar es Salaam, Tanzania, using semi-structured interviews with 31 migrant farmers and seven key informants, revealed that migrant farmers contribute to urban food security through diverse crop cultivation and livestock keeping, enhancing food production and income generation. However, migrant farmers face major constraints including insecure land tenure, flooding, water scarcity, high input costs, and limited institutional support. City authorities institutionalize the marginalization of migrant farmers by treating urban agriculture as an informal and temporary activity, despite their critical contributions.

Virag Havasi · IntechOpen eBooks · Hungary (Miskolc)

This chapter examines the history of the green movement in Hungary, including its alignment with global environmental trends and domestic political events. A case study of Miskolc revealed a lack of cross-sectoral cooperation and diminished civic mobilization, mirroring national tendencies. Hungarian civil society and green organizations have less financial and social support, and while they adopt social innovations, they do not excel at creating them.

Baltazar Namwata · Journal of Agriculture and Agronomy (JAA) · Tanzania (Dodoma)

This mixed-methods study assessed the implementation of urban agriculture (UA) policies in Dodoma City Council, Tanzania, surveying 300 urban farmers. Findings revealed low farmer awareness of city planning (15.9%) and UA regulations (24.4%), limited access to extension services (25.4%) and credit (24.0%), and unreliable water sources for many (45.5%). The study concluded that supportive national policy recognition has not translated into effective local implementation, farmer awareness, reliable service delivery, or practical enforcement.

Muhammad Hussain, Saima Shaikh, Zahir Ahmad, Ihsanullah, George Kontakiotis, Andreas Dittmann · Ecological Questions · Pakistan (Multan City)

This study analyzed urban expansion patterns and their impact on agricultural land in Multan City, Pakistan, using remotely sensed data from 1990 to 2020. The built-up area increased from 75 km² in 1990 to 299 km² in 2020, representing an annual increase of 9.5%. This growth converted approximately 31% (100 km²) of fertile agricultural land into built-up areas, with predictions of further increases of 54% by 2030 and 67% by 2040.

Blaž Križnik, Laura Mittermaier · Local Environment · Slovenia (Ljubljana)

This study examined the Onkraj gradbišča community garden in Ljubljana to understand how community gardening enables transformative social change and how institutional support affects it. Findings showed the garden fostered inner transformation, collective leadership, community capacity building, and some scaling strategies. However, scaling up strategies were ineffective, and the absence of institutional support limited the impact on governance, suggesting the garden's transformative potential for urban sustainability transitions was limited.

Adomas Gedvilas, Dovilė Krupickaitė · Journal of Architecture and Urbanism · Lithuania

This paper examines old community gardens in Grigiškės and Plungė, Lithuania, as examples of Everyday Urbanism, using literature, data, maps, and interviews. The study found that these gardens, established informally on vacant land during the socialist period, are not officially recognized and their future development may differ due to varying local government attitudes. This highlights the need for a more flexible approach to their preservation and integration into urban planning.

This study introduced a social impact accounting framework, "accounting for the loops," for sustainability education for climate action (SECA), applying it to a university-led community garden case study. It found that a sense of belonging and personal recognition activate positive reinforcing loops. However, project size and community autonomy counterintuitively triggered balancing loops, leading to increased bureaucratic obstacles and institutional support needs, which negatively impacted participant motivation.

This systematic review aims to explore the barriers to urban agriculture at a global scale. Recent years have seen a dramatic increase in systematic reviews concerning urban agriculture's health benefits, motivations for participation, and sustainability elements. This study will focus on the challenges and obstacles in implementing urban agriculture.

Adan Iddrisu · DOAJ (DOAJ: Directory of Open Access Journals) · Ghana

This policy brief explored the causes of farmland loss and its effects on the livelihoods of smallholder farmers in the Northern Region of Ghana due to rapid urbanization. Using data from focus group discussions, findings revealed that loss of farmland reduces productivity, increases household food security vulnerability, and threatens the livelihoods of farmers.

Thulani Dube, Bright Chisadza, Nkululeko Mpofu, Abel Mungure, Nancy N Manase · Journal of Hunger & Environmental Nutrition · Zimbabwe (Bulawayo)

A study in Bulawayo, Zimbabwe, investigating urban food insecurity resilience strategies through 200 household surveys, found that 50.5% of households experienced food insecurity, primarily driven by hyperinflation and unemployment. Current interventions, including urban agriculture, showed mixed effectiveness due to fragmented coordination and rural-biased programming, indicating governance challenges.

Nina Oher, Anna Bengtsson, Patrik Grahn · Land · Global

This study aimed to understand the evidence-based design process behind a rooftop garden at an urban Memory Clinic. Through focus group interviews with healthcare professionals and an interview with the landscape architect, findings showed that while the garden exceeded expectations regarding aesthetics, restorative qualities, and staff use, it was not used for patient-oriented therapeutic activities as intended. This divergence was linked to governance issues such as organizational change, loss of key actors, insufficient documentation of design intentions, procurement disruptions, shifting clinical priorities, and maintenance arrangements.

Hamed Faghiri, Zulkornain Yusop, Zainal Abidin Mohamed · IOP Conference Series Earth and Environmental Science · Malaysia

This systematic review analyzed 46 studies published between 2010 and 2025 to assess the role of urban farming in enhancing food security in Malaysia. Findings indicate that urban farming positively impacts food accessibility, availability, and affordability, while also promoting environmental sustainability and socio-economic inclusion. However, challenges such as limited space, regulatory hurdles, and public awareness gaps hinder its widespread adoption.

Rabia Admin, Malka Shahzadi, Malika Shahzadi, Muhammed Faisal Rasheed · Social Sciences Spectrum · Pakistan

This study examines women's involvement and empowerment in agricultural activities in Lahore Cantonment, Punjab, Pakistan, based on data from 118 women engaged in agriculture, analyzed using mixed methods including descriptive statistics, chi-square tests, correlation, and multiple regression. The results show that while participation rates among women are high, women are not yet empowered, owing to existing socio-cultural and resource-based obstacles. Significant associations were found between land ownership and women's decision-making, between education and participation, and between access to credit and extension services and involvement in agricultural activities; the correlation matrix showed positive relationships among key variables, and regression analysis identified land ownership, education, and access to credit as significant predictors of women's empowerment. The paper states that changes to law, access to resources, and social support are needed to improve women's agency in peri-urban agriculture, and proposes policy measures including land rights reform, targeted educational initiatives, and improved access to resources.

Birhanu MW, Negussie ZT · The Scientific World Journal · エチオピア

A PRISMA-based review synthesising peer-reviewed articles published between 2015 and 2025 on the status, challenges and opportunities of home and urban vegetable gardening in Ethiopia. It frames urban and home-based gardening as a practical response to food insecurity, malnutrition and environmental degradation in rapidly urbanising areas where the search for better opportunities has driven rising unemployment and limited access to nutritious, affordable food. The barriers it identifies — limited access to land and clean water, gendered barriers to women, limited technical knowledge, inadequate extension services and weak institutional support — all hinder production and sustainability. It further notes that widespread irrigation with untreated wastewater poses significant health and environmental risks through heavy-metal contamination and soil-transmitted infectious disease. Opportunities such as using vacant urban lots, promoting vertical gardening and supporting local seed production remain untapped; government support for urban gardening has grown recently but its implementation remains inconsistent. The review also identifies a significant geographical gap within the existing literature.

US community gardens embody a conundrum: vital to community well-being and integral to urban social infrastructure, yet profoundly vulnerable through insecure land tenure, fragmented policy support and systemic disinvestment. This reflective essay examines the Philadelphia Garden Data Collaborative (PGDC), a multistakeholder initiative documenting, protecting and advocating for community-managed green space, from the authors' position as participant researchers. It traces the shift from grassroots mapping to coordinated data stewardship, which enabled both emergency interventions (such as preventing sheriff-sale evictions) and long-term preservation strategies, and examines the ethical dilemmas of collecting sensitive community data where bureaucratic neglect has rendered gardens invisible and where visibility can expose them to new risks. It concludes that data can strengthen advocacy and inform policy, but must be coupled with secure tenure mechanisms and sustained public investment.

Drawing on statistical and cartographic data, it shows a downward trend in the area of allotment gardens within cities.

Kanosvamhira T.P., Magidi M. · International Journal of Agricultural Sustainability · 南アフリカ・ケープタウン／ジンバブエ・ノートン

A qualitative case study comparing the motivations, operational dynamics, land access challenges and legislative contexts of urban agriculture in two contrasting cities — Cape Town (South Africa) and Norton (Zimbabwe) — through stakeholder interviews and policy analysis, guided by social capital theory. In Cape Town urban agriculture is semi-institutionalised, backed by governmental and civil society actors and framed within wider food justice and community development agendas, yet practitioners face significant constraints from land access, urban policy fragmentation and competition over space. In Norton it is largely informal, a survivalist response to persistent socio-economic hardship with minimal formal support but relatively flexible regulation, where land-tenure insecurity and the threat of eviction are the pressing concerns. The paper argues that context-specific legislative frameworks, secure land rights and inclusive urban planning are the enabling conditions, situating urban agriculture within debates on land governance and urban informality.

Kissoly L. · Frontiers in Sustainable Food Systems · タンザニア・ダルエスサラーム

An exploratory qualitative case study and policy analysis of urban agriculture's current landscape and possible futures in rapidly urbanizing Dar es Salaam, drawing on targeted literature and document review, a policy and regulatory scan, and 52 key informant interviews with municipal actors, urban farmers and food-system practitioners conducted between April and September 2025. Urban agriculture is valued for household food supplementation, small-scale income and fresh-food provisioning through short-cycle vegetable production close to consumers, but remains shaped by tolerated informality, insecure land access, fragmented regulation, contamination risks, weak institutional coordination and pressure on peri-urban land. Five evidence-informed trajectories are proposed — managed river-corridor cultivation; sacks, buckets and roofs for dense-ward micro-production; institutional land clusters; peri-urban foodshed belts with circular-resource hubs; and small-scale aquaculture with insect-based feed — presented explicitly not as tested feasibility models but as differentiated options requiring further technical, environmental, spatial and economic assessment. The paper argues the future depends not on a single large-scale model but on risk-sensitive, institutionally grounded forms of support.

Arild Eriksen, Deni Ruggeri, Esben Slaatrem Titland · · Norway (Oslo)

This essay examines urban agriculture from the perspective of an architect and urban farmer/beekeeper practicing bottom-up, participatory design in Oslo. Critical dimensions of urban agriculture in public space include private and corporate claims on these landscapes, and its current aesthetics of impermanence are critiqued. The essay questions the notion that the joy and freedom urban agriculture brings to a community should be built upon and enriched by future development and policy.

Md. Ashikuzzaman, Mohammad Shahidul Hasan Swapan, Atiq Zaman, Yongze Song · Sustainability · Bangladesh (Dhaka)

This study explored the connection between organizational rational choice in urban rooftop farm (URF) policy development and social innovation, using a literature review and a case study of Dhaka, Bangladesh. Despite the rising popularity of URFs in Dhaka, existing policies and strategies were found to lack clarity and governing mechanisms are absent. The findings suggest that a participatory and co-productive approach, involving community members, local governments, and NGOs, is optimal for URF policy formulation and successful governance.

Francis Mwaijande · African Journal of Empirical Research · Tanzania

This study, using a mixed-methods approach with 600 respondents from urban and peri-urban farmers and agri-food supply chain producers in Tanzania, confirmed urban agriculture's contribution to food availability, accessibility, stability, and utilization. However, it found that urban agriculture is not well-integrated into urban food and poverty reduction policies in Tanzania and is practiced without legitimate policy and legal frameworks. This policy gap indicates an inadequate policy enabling environment for urban agriculture to enhance food security.

James Mbugua · African Journal of Climate Change and Resource Sustainability · Global

Biochar is presented as a promising nature-based solution for urban resilience, applicable in soil remediation, stormwater management, and carbon sequestration within green infrastructure. However, its widespread adoption faces significant barriers, including inconsistent feedstock supply, high production costs, limited public awareness, and a lack of standardized quality and safety regulations. The study also identifies a critical need for policies that integrate biochar into urban planning frameworks and incentivize its production and application.

Firdavs Berdikulov, Iroda Orifjonova, Bekhzod Eshboev, Jumanazar Xolmurzayev, Bakhtiyor Abdusayitov · Springer Link (Chiba Institute of Technology) · Uzbekistan (Samarkand)

This study examined agricultural growth in Samarkand, Uzbekistan's peri-urban regions from 2000 to 2024, using government data and predictive modeling. It found that urban populations surged while arable land declined, and the vegetable surplus, though currently meeting demand, began shrinking around 2015, suggesting a tipping point toward shortages. The research indicates that without proactive measures like smarter land allocation and advanced irrigation, Samarkand risks a structural food deficit within a decade.

Popov, Velian · reposiTUm (TU Wien) · Bulgaria (Plovdiv)

This study examines the disappearing phenomenon of informal urban gardening, known as Rancho, in Plovdiv, Bulgaria, focusing on its socio-historical factors. Despite its authentic, decades-long existence, Rancho is neglected and considered outdated, with a lack of legal regulation and its informal character endangering its future. The study proposes a gradual transformation of these areas into community urban gardens with new infrastructures to raise awareness and encourage authorities to reintegrate Rancho into the urban context.
