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.

This study examined environmental, technological, and socio-economic determinants influencing the ecological viability of AI integration in Kinshasa's peri-urban agriculture, which faces threats like soil degradation and inadequate infrastructure. A field survey of 411 farmers in the Kimwenza area found 86.13% viewed AI positively despite major structural constraints, including lack of electricity (78.83%) and digital illiteracy (54.99%). The study highlights the current lack of anticipatory public policies to address these constraints for a sustainable digital transformation.

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.

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.

This thesis explores improving Dominica's urban agricultural sector, examining challenges like hurricanes, landslides, temperature shifts, limited adoption of advanced farming techniques, an aging farmer population, and soil erosion. The proposed Agricultural Learning Facility aims to address these issues by leveraging smart farming methods and enhancing traditional practices. However, the proposed greenhouse and hydroponic systems cannot completely replace traditional farming practices, but rather help increase food production.

This review synthesizes the concept, design principles, carbon sequestration mechanisms, storage potential, and environmental benefits of carbon gardens, which are multifunctional landscapes designed to maximize carbon sequestration and deliver a wide range of ecosystem services. The article highlights their application in urban and rural landscapes and their integration with carbon-negative farming through practices such as biochar use and compost recycling. It also discusses key challenges related to carbon measurement, establishment costs, land availability, and long-term management.

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.

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.

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.

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.

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.

In Argentina, public policies like the Argentine Plan Against Hunger and the ProHuerta Program have stimulated urban agriculture to address the food emergency crisis in early 2024. Despite urban gardening being recognized as a crisis-addressing strategy, the existence and future forms of public policies supporting urban gardens remain uncertain amid recent national political changes. Several barriers to integration and consolidation of these programs are highlighted.

This study in Greater Lomé, Togo, interviewed 11 experts and surveyed urban farmers to compare their perceptions of urban agriculture and health. The findings reveal a disconnect: urban farmers identify various challenges, including health-related difficulties, while experts tend to assume different health concerns, highlighting a misalignment between the perspectives of planning and design experts and urban farmers.

Cindy Vong · Journal of Food Law & Policy · Global

This Note argues that municipalities in the United States should permit on-site slaughter of backyard chickens on private residential property. Historically, local governments codified the separation of residential and agricultural uses, leading to bans and restrictions on urban agriculture. The current regulatory vacuum for urban agriculture creates conflicts and uncertainties, and allowing backyard slaughter could strengthen local food systems and regulate a growing urban practice.

Ylva Wallinder, Maria Langa · Environmental Sociology · Sweden

A study investigated the consequences of institutional policy change on urban gardening practices in Swedish municipalities over the last decade. Local sustainability policies have led to an increasingly business-centered model, which clashes even with entrepreneurial gardens. This shift caused associational gardening to give way to an extended focus on entrepreneurship and food production, representing a "green rationalization" of gardening practices in urban sustainability policies that hinders their sustainability potential.

Chiara Tornaghi · · Global

This chapter, based on 15 years of research, identifies key shortcomings in urban planning policy that prevent urban agriculture from reaching its full potential for human and non-human health. These include the failure to recognize urban agriculture as food production, the invisibility of soil and its role, and the neglect of soil care and food production specialists in public land design and soil management. The chapter suggests that agroecological considerations can enhance urban agriculture's ambition in public spaces.

Ioana Florea · Environmental Sociology · Romania

This paper investigated three collective gardening projects in Bucharest that closed between 2019 and 2021, analyzing what remains of their sustainability capacities and commoning efforts after termination. Findings indicate that while essential commoning aspects like collectivity building and autonomy can endure and transfer to other spaces, cross-class aspects fade away with these transpositions. This reveals that what persists from closed gardening projects is strongly tied to structural historical contexts.

Sara Ramezani, Mahin Nastaran, Homayoon Nooraie, Kei Otsuki · Journal of Landscape Ecology · Iran

A study investigating urban agriculture land use changes in Damavand, Iran, from 1995 to 2022 found a 109% increase in built-up land and declines of 14.34% in barren land and 22.44% in vegetation, including urban agriculture lands. Interviews with 15 participants identified land value changes, attraction to urban livelihoods, management and planning factors, physical-environmental factors, and urban infrastructure availability as primary reasons for these changes. The research highlights the urgent need for effective planning to mitigate threats from extensive urban agriculture transformations.

Dennis Raphael · Policy Press eBooks · Global

This chapter documents the growth of charitable non-governmental responses to food insecurity in Canada and the UK, including food banks and community gardens. It argues that these responses are problematic because they fail to address the economic and political causes of food insecurity. Further failures include the stigma experienced by food bank users and the false belief that food insecurity is being resolved.

Odeimy Sarría-Crespo, Mayelin López-Roque, Wilfredo Sis-Sánchez · Revista Metropolitana de Ciencias Aplicadas · Cuba (Cienfuegos)

A ten-month non-experimental study at the "Pueblo Griffo Viejo" organic farm in Cienfuegos, Cuba, identified limiting factors in vegetable production through surveys, field observations, and documentary review. The research found low yields due to poor substrate quality, inadequate water management, limited organic matter, and insufficient training participation. Additionally, the workforce's low educational level hindered efficient agricultural practices.

Michaela Pixová, Christina Plank · Environmental Sociology · Czechia (Prague, Brno)

This paper compared the roles of allotment and community gardens in urban sustainability, using Prague and Brno, Czechia, as case studies. It analyzed perceptions of both by municipal actors, gardeners, and activists across four dimensions: public access to urban greenery, community building, food cultivation, and environment/climate protection. The paper argues that governments' preference for gardens aligned with the status quo undermines citizens' right to the city, urban sustainability, and resilience against future threats.

Gabriela Civeira, Florencia Rositano · Conicet · Argentina (Buenos Aires)

This study analyzed the environmental, social, and economic factors of agricultural production in the Buenos Aires Metropolitan Region (RMBA) across 28 municipalities, using National Agricultural Census data and an adapted ecosystem services (SE) estimation model. Findings indicated that 97.4% of small and medium-sized horticultural producers use conventional management, with only 2.6% employing non-conventional practices. Structural problems identified include informal labor, limited technical access, and urban pressure, highlighting the need for public policies to strengthen more sustainable production systems.
