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.

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.

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

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.

This narrative review synthesized the ecosystem services of urban food forests and their contributions to urban health and food sustainability in North American cities. Based on 13 studies published between 2018 and 2023, it identified that food forests provide services such as sustainable food production and climate regulation. However, their implementation faces challenges including public space governance, maintenance costs, regulatory barriers, and ecological risks like invasive species.

Marina Abrão Ballak Dias · Revista Andaluza de Antropología · France (Paris)

This article explored how different conceptions of human-nature relationships shaped practices in two community gardens in Paris's Goutte d’Or neighborhood. Conceptions grounded in a human–nature divide prevailed, leading to a conservationist approach. Practices stemming from this perspective were found to be in constant tension with garden goals like increasing urban biodiversity and human socialization.

Belma Soto-Fernández, Lurys Bourdett-Stanziola · Asian Journal of Agricultural and Horticultural Research · Latin America

A documentary review on the importance of urban gardening in Latin America revealed that urban gardening, when approached through the lens of agrobiodiversity, has become a key strategy for safe food production and environmental sustainability. However, it was found that several Latin American countries lack clear and established laws to regulate this activity. Preliminary evidence of rotavirus was detected in fresh vegetables from an urban garden in Panama, indicating that urban gardens can become infection foci capable of causing diseases of public health and veterinary importance.

Jelena Salmi, Anna Krzywoszynska · Environmental Science & Policy · Finland

A discourse analysis of 103 governance and grey literature documents in Finland examined the politics of soil biodiversity indicators. The study found that eDNA is the preferred scientific basis for soil biodiversity governance in Finland due to alignment between scientific and policy groups. However, land workers' organizations criticize eDNA methods, arguing they risk obscuring local specificity and creating environmental and social injustice, potentially alienating land management groups.

Rueda, Ximena · Socio-Environmental Systems Modeling · Africa

A 2025 comparative analysis examines agricultural, economic, and biodiversity policy across Cameroon, Kenya, and Colombia in the context of agricultural expansion, using discourse analysis of policy documents via the Nature Futures Framework and Life Frames Framework, an evaluation of budgets allocated to major agricultural and biodiversity policies, and stakeholder interviews. It finds a shared struggle across all three countries to harmonize agricultural development with biodiversity conservation despite differing institutional capacities, historical pathways, and sociocultural contexts, with agriculture continuing to dominate policy agendas and resource allocation even as recognition of biodiversity's importance grows. Nature is framed primarily in instrumental terms, most strongly so in Colombia's utilitarian "Nature for Society" orientation, with intrinsic and relational values rooted in Indigenous cosmologies weakly reflected in implementation; funding for biodiversity-related ministries remains minimal relative to agriculture in all three countries — Kenya's environmental budget rarely exceeds 0.3% of national expenditure, with Cameroon showing similar disparities and Colombia's allocations continuing to favor agricultural expansion — and institutional fragmentation further undermines this governance.

Ermias Debie · City and Environment Interactions · Ethiopia

A study in Bahir Dar, Ethiopia examined the integration of urban agriculture (UA) and green infrastructure (GI) through surveys and interviews with 99 stakeholders, supplemented by participatory observation. The main barriers to integration, based on multiple-response data, were a lack of supportive policies and regulatory frameworks (87%), limited awareness (57%), and space constraints (51%). Multicriteria decision analysis ranked integrated practices as the most effective strategy (score 16.81), followed by edible tree planting at garden centers (16.18), small gardens (13.83), and fence-edge greening (11.46). Structural equation modeling identified thermal regulation and access to fresh food as critical factors for planning sustainable urban systems.

Bauer W., Titz A. · Nature-Based Solutions · Malawi (Lilongwe)

Urban Nature-based Solutions (NbS) are promoted globally as multifunctional and cost-effective, and municipal interest is growing in cities of the so-called Global South. Yet research remains clearly biased toward the Global North, with particularly few studies on cities in Sub-Saharan Africa — leaving a high risk that maladapted NbS, modelled on examples from elsewhere that do not meet local requirements, get adopted. This article examines the barriers to adopting urban NbS in Malawi's cities and the opportunities for successful implementation, drawing on qualitative data (workshops, narrative expert interviews, group discussions) gathered over five research stays in Lilongwe between 2022 and 2024, and analysing in detail the strategies used by those implementing the Lilongwe Ecological Corridor Initiative (LECI), a large-scale NbS in the capital.

This chapter examines the diverse uses of urban green spaces, encompassing recreation, biodiversity conservation, public health, and regulatory ecosystem services, with food production also re-emerging. Changing urban populations, including cultural diversity and ageing, have altered demands and uses. The study identifies a critical need to manage potential conflicts and trade-offs among these varied demands, despite many uses being able to coexist.

This study evaluated land cover change and its drivers using spatial and statistical analysis in 22 designated protected areas (PAs) across the tropical coastal regions of sub-Saharan Africa. Results indicated that food production is prevalent in these protected areas regardless of their designation, and forest loss occurred in most PAs, suggesting weak conservation. Population density was the most significant driver of land cover change, and only 15 out of 22 protected areas showed an increase in their total ecosystem service value.

Setyardi Pratika Mulya, Heru Purboyo Hidayat Putro, Delik Hudalah · Geography and sustainability · Global

This 2023 global systematic literature review examined peri-urban agriculture (PUA) as an ecosystem service, focusing on urbanization pressures and governance. The review found that PUA is crucial for urban areas in terms of food supply, ecology, biodiversity preservation, disaster mitigation, and recreation. However, massive urban expansion is a primary cause of PUA loss, and sociocultural biases have led to institutional constraints on peri-urban management within existing political and regulatory frameworks.

Gizaw Ebissa, Kumelachew Yeshitela, Hayal Desta, Aramde Fetene · Environment Development and Sustainability · Global

This study investigated urban agriculture's (UA) contributions to environmental sustainability (ES) using scholarly search engines. Findings indicate UA contributes to ES by mitigating greenhouse gases, urban heat island effects, and floods, while enhancing biodiversity and promoting agro-tourism. However, challenges such as lack of policy support, exclusion from urban land use planning, and urbanites' behavior towards UA products limit its full benefits.

Nancy Harlet Esquivel-Marín, Leticia Myriam Sagarnaga Villegas, Octavio T. Barrera-Perales, Juan Antonio Lugo Machado, José María Salas González · Acta Universitatis Sapientiae Agriculture and Environment · Europe

This bibliometric review analyzes the systemic structure of multifunctional agriculture (MFA) and its relationship to sustainability, based on a sample of 432 documents published on the Web of Science platform. Using Bibliometrix and VOSviewer to map scientific collaboration networks, the review identified the authors, journals, and countries shaping the current knowledge structure and four thematic clusters: (a) MFA and sustainability, (b) ecosystem services and biodiversity, (c) European public policies, and (d) governance and urban agriculture. It concludes that, despite an increase in publication rates, research remains concentrated in Europe with few collaborative networks across disciplines, indicating that SDG 17 (partnerships) is not being achieved.

A study in Detroit's Lower Eastside (~15 sq. miles) examined the spatial extent, characteristics, and residents' perceptions of urban gardens using spatial analysis and interviews. Gardens covered less than 1% of vacant land and were often ephemeral. Primary obstacles to scaling up urban agriculture in Detroit include uncertainty over land tenure, environmental pollutants, potential ecosystem disservices, and a lack of government support and capital investment.

This study investigated the impact of perceived ecosystem services (ES) and disservices (EDS) on behavioral intention towards urban community gardens (UCGs) among 1142 residents in Changsha, China. While government decision-makers often refuse UCGs, residents' attitudes, perceived behavioral control, and subjective norms positively impacted their behavioral intention towards UCGs. Perceived ES had a direct positive impact on behavioral intention, whereas perceived EDS had a direct negative impact.
