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.

The capacity of Family Allotment Gardens (FAGs) in Warsaw, Poland, to provide air-pollution filtration and microclimate regulation was quantified. Particulate matter, air temperature, and relative humidity were measured inside and outside three allotment complexes in autumn 2023. Results showed a moderate reduction in PM concentrations inside gardens (by about 2 µg/m³) and slightly higher humidity (2.1%). However, the cooling effect was weak (less than 0.3 °C), indicating a limited spatial range under autumn conditions.

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.

YeunSook Lee, Jaehyun Park, Yumi Hwang · Journal of the Korean housing association · South Korea

A longitudinal qualitative case study in a South Korean senior public rental housing community examined the first transition to self-governance in a rooftop community garden. The transition led to ecological and sensory degradation, including disrupted ecological rhythm and reduced olfactory comfort, and social fragmentation with disputes and leadership frictions. These findings revealed limits of participation-heavy models without codified rules or procedural safeguards, indicating that effective self-governance requires visible rules, procedural fairness, embedded learning, and mediation structures.

Natalie Meyer, Simona Trandafir · Journal of Environmental Economics and Policy · United States (Rhode Island)

A choice-based survey of over 600 US residents from Rhode Island examined preferences and perceived value for green rooftop (GR) space allocations for agriculture, solar energy, and recreation. Latent class modeling revealed that Class 1, representing 20% of respondents, was generally unsupportive of GR installation and expressed disutility towards GR space allocation for solar energy. Both classes uniformly favored allocating GR space for agriculture production and showed a positive willingness to pay for this feature.

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.

James Vandenberg, Kerstin Krellenberg · Sustainable Cities and Society · Global

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.

Strayker Ali Muda, Heripan Heripan, Fitra Gustiar · Springer Link (Chiba Institute of Technology) · Indonesia (Palembang)

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.

Serafina Stone, Jeremy Farr, Damian Hine, Yasmina Sultanbawa, S. K. Fyfe · Local Environment · Australia (Brisbane)

This research investigated how 16 members of four urban community gardens in Brisbane, Australia, derive value from their involvement in relation to the food system, using semi-structured interviews and participant observation. The findings indicate that while urban community gardens alone cannot address food security needs, they provide spaces for building community, generating social capital, connecting to nature, and developing food systems education. These benefits are contingent on the gardens' continued existence and primarily extend to those able to participate.

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.

Charlotte Potter, Silvia Sarapura, Camilo Jimenez Gonzalez, Justina Walker-Mohamed, Paul Benalcazer, Biinjitiwaabik Zaagging Anishinaabek, Netmizaaggamig Nishnabeg, Red Rock Indian Band · Rural Review Ontario Rural Planning Development and Policy · Canada (Northern Ontario)

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.

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.

Isabela Thomas Mkude · TANZANIA JOURNAL OF SCIENCE AND TECHNOLOGY · Tanzania (Dar es Salaam)

In Dar es Salaam, Tanzania, the utilization of faecal sludge derived compost (FSDC) by urban farmers remains limited due to farmers' prejudice and hesitance. This study investigated factors influencing FSDC acceptance through a cross-sectional survey of 76 urban farmers. Results indicated that garden location in communal areas, income generation as the primary farming purpose, and accessibility of soil inputs were significantly associated with FSDC acceptance. Farmers' awareness and experience also played important roles.

This paper describes a class-based soil testing project where undergraduate students partner with local community gardeners to investigate urban soil health. The project involves students examining soil properties such as pH, organic matter, nutrients, and toxic elements, and ensuring crop safety. Students develop project plans, interpret data, and make recommendations for soil management.

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.

Charlotte Gallagher, Daniel López-García, Parisi, Anton, Cuevas, Soledad · Zenodo (CERN European Organization for Nuclear Research) · Europe

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.

This study examines the relationship between climate change, urbanization, and urban and peri-urban agriculture in Guarapuava-PR, Brazil. It emphasizes how regional atmospheric variability intensifies existing socio-environmental vulnerabilities. Guarapuava's climate, characterized by high thermal amplitude, frequent frosts, and irregular rainfall, significantly conditions agricultural production systems, especially in urban and peri-urban areas, negatively affecting productive cycles.

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.
