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.

A study investigated school garden programs in elementary schools, exploring the experiences of fifteen teachers, staff, and students using a descriptive phenomenological approach and open-ended questionnaires. It found benefits in academic learning, environmental awareness, health, and social development, but also identified challenges including resource constraints, time limitations, garden maintenance, and stakeholder engagement. These challenges require careful planning, collaboration, and creative solutions.

A study of Katowice (Poland) and Brno (Czech Republic) examining how family allotment gardens function as greenery in city centres, together with the legal regulations that govern them. 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.

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.

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.

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 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.

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.

A study mapped and quantified urban growth and land use in Córdoba, Argentina's Green Belt. Using remote sensing and GIS, it evaluated urban growth between 1974 and 2014 and land use in peri-urban and rural areas in 2015. The study revealed a 46.5% urban area growth over nearly 40 years, alongside an increase in farm plot size, indicating land ownership concentration and a reduced number of producers. This transformation highlights a conflict between peri-urban horticulture, industrial agriculture, and urban development.

This research evaluated the limits and possibilities of learning ecological interactions in elementary school using a school garden, involving a supervising teacher, a classroom teacher, and 30 students. While students demonstrated understanding of ecological interactions through oral communication, the study identified significant limitations including difficulties in reading and writing, a lack of volunteers, and insufficient technical and administrative support from the school.

Community gardens can serve as important local greenspaces to address environmental degradation and educate individuals about the importance of food and the environment. However, certain barriers need to be overcome and addressed before community gardens are successfully implemented. Participation and interaction within community gardens may provide a pathway to long-term commitment to sustainability, encouraging individuals to adopt more environmentally supportive behaviors and a deeper commitment to environmentalism.

This report examines the global rise of urban beekeeping, noting its diverse approaches across countries like the UK, Japan, and Denmark. While South Korea has seen an increase in urban beekeeping since 2012, with government support initiated in 2016, the sector faces significant challenges. Urban beekeeping is still largely viewed as a derivative of conventional beekeeping, and a lack of ordinances or legal frameworks hinders its widespread adoption and recognition of its environmental, social, and economic value.

Ari Jokinen, Ville Viljanen, Krista Willman · Alue ja Ympäristö · Finland (Tampere)

This article analyzes the social and ecological significance of the Pispala allotment area in Tampere, Finland, where nearly 300 plots are used for urban farming, despite city plans for building purposes. A mixed-method analysis, using field observation, planning documents, biological surveys, and questionnaires, found that farming practices make the place visible, foster social interaction, and link the site ecologically to rare plant species. However, these crucial features of urban diversity are frequently disregarded by local administrative bodies in planning.
