This qualitative literature review examines informal green spaces (IGS) in Chinese cities, contrasting them with formal, hyper-managed landscapes. The study finds that while formal lawns incur high financial maintenance burdens and lower biodiversity, IGS, including spontaneous urban wilderness and community gardens, are often cleared despite offering higher biodiversity and zero maintenance costs. The research highlights a governance dilemma where the prioritization of neatness over ecology leads to the removal of IGS, which support psychological place attachment and spatial justice for marginalized groups.

This study investigated how differentiated configurations of outdoor, indoor, and greenhouse urban agriculture (UA) impact Urban Resilience Capacities (URCs). It found that a strategic, place-based, combinatorial approach to integrating UA typologies can produce mutually reinforcing outcomes, strengthening various URCs simultaneously. However, a strong risk of trade-offs exists when UA systems are not aligned, and a critical research gap remains as empirical case studies are concentrated in Europe and North America, overlooking experiences in the Global South.

This study analyzed the integration of Controlled Environment Agriculture (CEA), community gardens, and public health policies, using case studies from Brazilian cities such as Salvador, Recife, São Paulo, and Rio de Janeiro. CEA contributes to enhanced productivity in small spaces with reduced water and input consumption, while community gardens strengthen social cohesion, mental health, and local food supply. However, challenges remain regarding high implementation costs, regulatory gaps, and lack of institutional support.

This systematic review examined strategies, trade-offs, and synergies of climate-smart urban agriculture relevant to Palembang City, Indonesia. A total of 400 records were identified from Google Scholar and Scopus, with 352 unique records screened. While urban agriculture showed five key contributions, including strengthening food security, several critical trade-offs were identified, such as land scarcity, energy and water requirements, soil contamination risks, technological costs, and policy fragmentation. The review emphasizes that urban agriculture should be part of a broader transformation of urban food systems, not a stand-alone solution.

Jana Marion Böhme · PubData · Europe

This study investigated the current state and professionality of biodiversity monitoring in food forest projects and influencing social-ecological factors through an online survey and interviews with German and Dutch experts. It found heterogeneous characteristics and professionality levels in monitoring activities, primarily due to context factors like actors, governance systems, and socio-economic settings. The professionality of monitoring depended on volunteer and expert availability and funding, indicating a lack of integrated, standardized, and systematic monitoring concepts and institutionalization.

Gitanjali Nanda · International Journal for Research in Applied Science and Engineering Technology · India (Bhubaneswar)

This study examined the spatial, institutional, and planning feasibility of integrating urban agriculture into the urban planning structure of Bhubaneswar, India. Using a mixed-method planning framework, it evaluated urban land availability, rooftop feasibility, food accessibility, supply-chain dependency, institutional readiness, and decentralized food-production potential. Findings indicated that urban agriculture integration within statutory planning systems remains limited in rapidly urbanizing Indian cities, and vendor assessments showed strong dependence on peri-urban and external food inflows contributing to seasonal price instability and food wastage.

The 'Braiding Food Systems' project, a community-led partnership with three Northern Ontario First Nations, used mixed-methods Participatory Action Research to examine conditions influencing food security and sovereignty. Community members identified structural constraints rooted in colonial governance, contemporary ecological pressures, and local transformation opportunities. This research demonstrates that sustained, community-led collaboration can counterbalance colonial food systems by reorganizing decisions, strengthening access, and enhancing resilience within Indigenous food networks.

Elisa Carvalho Lauer, Jaqueline Lima Liskoski, Kelliane Da Consolação Fuscaldi · Revista Campo-Território · Brazil

This study mapped and analyzed urban and peri-urban agriculture (AUP) legislation across municipal, state, and federal levels in Brazil, identifying 217 municipal laws in 113 municipalities, 33 state laws, and federal frameworks. The research systematized normative content into twelve thematic categories, showing AUP's integration into food security, urban sustainability, and income generation agendas. While a qualitatively consistent normative basis exists, gaps persist regarding conceptual definition, area guarantees, water access, financing, and credit. It is necessary to expand and harmonize regulations across all three spheres to consolidate AUP as a structural strategy for sustainable cities.

Amare Molla Dinku, Goedele Van den Broeck · International Journal of Agricultural Sustainability · Ethiopia

This qualitative study explored the technical, institutional, and commercial aspects of urban agriculture (UA) in two Ethiopian secondary towns, Dessie and Kombolcha, through 68 key informant interviews and 11 focus group discussions. It found that nearly 90% of local leafy vegetables are sourced via UA, but insecure land rights, limited policy support, and informal trading systems hinder its impact. Informal markets also cause post-harvest losses, disproportionately affecting women.

Hoyoon Jung · The International Journal of Social Sustainability in Economic Social and Cultural Context · Brazil (Belo Horizonte)

This study analyzes Belo Horizonte, Brazil's right-to-food model, which has reduced hunger and promoted social equity through integrated food policies like subsidized food programs and urban agriculture. Despite its successes, the model faces challenges in policy sustainability, financial constraints, and political continuity, and the study notes limitations including reliance on secondary data.

Gang Wang · Agricultural History · China (Shanghai)

This historical analysis of Shanghai's vegetable supply system examines the limitations of peri-urban agriculture. In the early 1950s, Shanghai relied on distant rural areas for vegetables, shifting to suburban production in 1958 after rural sources were cut off. Efforts to sustain this suburban-centric system faced challenges, and government attempts to phase out the planned economy in the 1980s had limited effect. By the early 1990s, the suburban-centric system was abandoned, leading to a return to nonlocal vegetable predominance.

This study evaluated vertical farming (VF) through the resource nexus (RN) lens, emphasizing the interdependencies among energy, water, land, and materials. While VF offers advantages such as space efficiency, water conservation, and climate resilience, it was found to entail high energy demands, material dependencies, and economic feasibility challenges. An overview of these synergies and constraints helps identify mitigation strategies like circular water systems and hybrid renewable energy solutions.

This study analyzed the degradation of interest in grape cultivation in Boyaoge Village, Indonesia, from the perspective of architecture and urban agriculture. Using field observations, interviews with local farmers, and spatial analysis, the findings indicated that the main causes were the shift in land use from agriculture to settlements, a lack of infrastructure support such as efficient irrigation systems and market accessibility, and non-agricultural-friendly spatial designs including limited green open spaces and limited use of agricultural technology. These factors contribute to the decline in grape cultivation interest.

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.

Mesut YILDIZ · Agroecology and Sustainable Food Systems · Turkey (İzmir)

The Kadifekale Urban Orchard in İzmir, Turkey, was analyzed as a qualitative case study, showing that municipally supported urban agriculture functions as a relational public infrastructure reconfiguring women's labor, care responsibilities, solidarity networks, and public visibility. Based on one year of participant observation, in-depth interviews with 96 women, and focus group discussions, findings revealed women use the orchard to create space outside the home, build solidaristic ties, and increase public visibility. However, the case also revealed a persistent governance tension: municipal support is indispensable, yet women's influence over strategic decisions remains limited.

An outcome report from strategic workshops in Valladolid, Flanders, and Wrocław, engaging 33 diverse local stakeholders, assessed key policy and governance challenges facing urban agriculture. The most urgent and actionable priority identified across all three regions is the lack of coordination and knowledge sharing, underscoring a critical need to build resilient urban agriculture coalitions. To address broader structural issues like land access, stakeholders emphasized bridging the urban-rural divide, overcoming political short-termism, and establishing a shared understanding of urban agriculture's multifunctionality.

Yang Hua, Yong Xu, Kan ZHOU, Jie FAN · 资源科学 · China

This study analyzed the spatiotemporal patterns of supply and demand for seven major agricultural products in the Beijing-Tianjin-Hebei (Jing-Jin-Ji) region from 2015 to 2022. It found that the region faces a dual risk of agricultural product supply-demand imbalance and spatial mismatch, with an overall surplus but local shortages. Specifically, Beijing and Tianjin generally lack self-sufficiency in agricultural products. The research proposes an integrated layout plan for high-quality agricultural bases to address these imbalances and ensure regional food security.

Sofyan Sufri, Jonatan Lassa · Environmental Hazards · Indonesia (Aceh)

This article examined the barriers and opportunities of the Climate Village Programme (ProKlim) in Aceh, Indonesia. Key stakeholder interviews (N=38) and policy content analysis in three villages within Banda Aceh city revealed hypothetical barriers to CCAM, including the absence of a sustained mechanism for effective flood adaptation, insufficient resources for supporting adaptive urban agriculture practices, lack of community participation, and inadequate integration of scientific and local knowledge into early warning systems. Despite ProKlim being an innovative program, challenges remained, as past disaster events were viewed as distant memories, hindering proactive risk reduction efforts by local authorities and residents.

This process evaluation assessed the reach, effectiveness, adoption, implementation, and maintenance of the New Brunswick School Food Pilot Project (NBSFPP) using the RE-AIM framework in eleven schools across New Brunswick, Canada. While school administrators reported positive impacts on program optimization, student leadership skills, food literacy, and eating behaviors, no significant effect was found on teachers’ perceptions of students’ diet or academic outcomes. Program sustainability was largely dependent on receiving funding.

Supriya Dadaso Dighe · Zenodo (CERN European Organization for Nuclear Research) · New Zealand

This study provides an eco-critical analysis of Eleanor Catton’s novel "Birnam Wood," exploring the entanglement of environmental activism, capitalist expansion, and identity formation. While the novel depicts conflicts between activist collectivism and corporate techno-capitalism through guerrilla gardening and land commodification, the study argues that its allegorical structure and reliance on familiar ideological binaries may constrain its capacity to generate radically new ecological insight. The research ultimately raises questions about the limits of literary representation in envisioning transformative environmental futures.

A study of the "Ceinture verte" (Green Belt) in Ouagadougou, Burkina Faso, as a nature-based response to climate adaptation. Established in 1976 and relaunched in 2018, the initiative combines forestry development with urban agriculture, aiming to contain urban sprawl, improve the local climate and strengthen the capital's resilience. The study combined a diachronic analysis of Landsat imagery from 1984-2024 with interviews of institutional actors, associative partners and direct beneficiaries. Results show significant contributions — expansion of dense vegetation in some areas, a perceived improvement in air quality, the creation of income-generating market-gardening activities, and the inclusion of vulnerable populations — but also reveal strong constraints: illegal occupations covering a significant share of the land, fragmented governance, limited access to water, security fragility, and still-limited involvement of local residents. The study discusses the feasibility of a trajectory to 2050 between an optimistic scenario conditional on structural reforms and a critical scenario underscoring current limits, and offers lessons transferable to urban adaptation policies in other Sahelian metropolises.

Framed within studies of racial capitalism and neoliberal corporate food regimes, this article examines how residents of Pennsylvania's Monongahela (Mon) Valley experience and articulate food apartheid — a racialized system of food access — and how it intersects with deindustrialization, capital abandonment, and structural racism. Drawing on engagements across three Mon Valley municipalities, the findings reveal complex geographies of food apartheid intersecting with other markers of racial capitalism: inequitable transportation infrastructure, rising cost of living alongside declining quality of life, and ineffective political representation. Residents interpret these inequities as part of a broader racialized economic injustice favoring neighboring, predominantly white municipalities, compounded by distrust of local government perceived as perpetuating exclusionary policies rather than responding to community demands. In this context, participants envision community-driven solutions that extend beyond food system and urban agriculture initiatives.

A documentary literature study examined urban agriculture in Gurupi, Tocantins, Brazil, where 288 productive units exist despite the municipal master plan and local legislation not explicitly addressing the practice, focusing on the need for municipal regulation. Drawing on federal, state, and municipal legislation, academic studies, territorial diagnostics, and empirical survey data from Primo et al. (2014), the study found that urban agriculture holds socio-environmental, food, and community relevance but faces a lack of technical assistance, legal insecurity, and scarce institutional support.

A study in Makassar City, Indonesia, evaluated the multidimensional sustainability of urban agriculture (UA) through expert discussions and semi-structured interviews with 23 purposively selected stakeholders including academics, practitioners, urban planners, legislators and government officials. A Multidimensional Scaling (MDS) approach compared sustainability indices from two previous studies, supplemented by prospective and interdependence analyses to identify key leverage factors. Results showed the overall sustainability status of UA in Makassar during 2016-2020 remained "less sustainable," with a multidimensional sustainability index of 43.02%; the ecological (51.84%) and technological (65.09%) dimensions improved to moderately sustainable status, while the economic (46.15%), social (49.81%) and institutional (39.20%) dimensions showed declining sustainability performance. The study proposes three policy directions: strengthening UA planning and management systems, improving institutional coordination among stakeholders, and expanding UA's socio-economic and environmental functions.

A Wageningen University Science Shop report examines measures to improve water management for the "duinlandjes", centuries-old allotment gardens in the dunes near Egmond aan Zee, Netherlands, that form part of the Zeesdorpenlandschap cultural heritage. Commissioned by the Duinlandjesvereniging de Noord association, it investigated sustainable solutions from sociocultural, hydrological and ecological perspectives. The duinlandjes are currently experiencing flooding that makes cultivation very challenging. A stakeholder analysis found that while collaboration between the association and drinking water company PWN has advanced, interactions among stakeholders remain fragmented, and it calls for the province of Noord-Holland to take an active coordinating role. The hydrological analysis identifies winter precipitation surplus as the main driver of rising groundwater, projecting that climate change will bring wetter winters and drier summers with greater groundwater fluctuation, though long-term groundwater trends remain uncertain while winter/spring water excess will probably continue. The ecological risk assessment highlights the vulnerability of surrounding dune habitats, noting that draining and diverting excess rainwater can cause habitat degradation and increased drought stress.
