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.

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.

Ilana Herold, Buhm Soon Park · International Journal of Urban and Regional Research · South Korea (Daejeon)

Ethnographic case studies of three urban community gardens in Daejeon, South Korea, illustrated how urban agriculture (UA) serves as a platform for civil society groups, national government, and local governments to advance their political and sociocultural goals. The study argued that while national UA legislation was passed to advance top-down sustainable development goals, local actors challenge the functions of UA and ideas of expertise through their practice.

Sara Sama Acedo, David Berná Serna, Patricia Homs Ramírez de la Piscina · Etnografica · Spain (Madrid)

This paper analyzes the case of community urban gardens in Madrid integrated into the Municipal Program of Community Urban Gardens. These initiatives are situated in the interstices between community management and public institutional management, generating new demands on the management of urban green commons and enabling forms of shared governance. The study reveals that these gardens face the challenge of maintaining themselves as transformative spaces without being absorbed by commercial logics or marginalized into welfare-oriented or community volunteer spaces.

This study analyzes criminal liability in cases where electrified cables, installed to protect crops from wild animals in community gardens, resulted in fatalities in the Aceh region of Indonesia. Using a normative legal research approach, the study of death cases in Bireuen and Aceh Timur showed that the installation of electrical cables leading to loss of life was caused by the perpetrator's negligence in adhering to safety standards, fulfilling elements of criminal negligence under Indonesian criminal law. The resolution pattern for these cases follows the litigation route.

Dorota Rancew-Sikora, Anna Horolets, Joanna Krukowska · Environmental Sociology · Poland

This article investigates how community gardening ideals are materialized and abandoned, applying Hannah Arendt’s distinction between types of work. Based on empirical analysis of narratives and observations in 12 gardens across Poland, the research demonstrates obstacles to democratic sustainability transitions. It proposes a processual concept of "slippage" to understand mechanisms by which departures from ideals occur in community gardens.

This study assessed the role of urban agriculture in Ghanaian cities through a systematic literature review of publications from 2000 to 2024. Urban agriculture was found to significantly contribute to food security, nutrition, and income, and to bolster environmental sustainability. However, challenges such as land tenure insecurity, unsafe irrigation practices, weak institutional support, and limited policy integration persist.

Sara Mahdizadeh, Yun Gao · Local Environment · United Kingdom

This qualitative study, based on 16 semi-structured interviews, examined motivations and barriers to participation in community gardens in Huddersfield, UK. Key motivations included social interaction, mental well-being, and skill development. Reported barriers were declining volunteer numbers, physical workload, limited institutional support, and accessibility challenges.

Emmanuel Ndhlovu · Discover Sustainability · South Africa

This article critically analyzed food system policies and actions in four South African cities, drawing from grey and academic documents. It found that the government is failing to achieve food security, with approximately 58 million people facing food insecurity in 2023. The study concludes that transforming South African food systems requires coherent policies, shortened supply chains, integration of food into urban planning, and increased support for farmers, among other actions.

Letícia Englete de Mello, Dirlane de Fátima do Carmo, Daiane Cecchin, Leonardo da Silva Hamacher, Marcel Carvalho Abreu, R. M. Anjos, Mariana Vezzone · Revista de Gestão Social e Ambiental · Brazil (Rio de Janeiro)

This study investigated the profile of 159 urban and peri-urban agricultural producers across 29 municipalities in Rio de Janeiro State, Brazil, using quantitative interviews and statistical analysis. Producers were predominantly men over 50 with limited education, cultivating small plots with organic methods but receiving little technical support. Key challenges identified were a lack of assistance and resources, and urban agriculture's potential is hindered by the absence of effective public policies.

Juan Camilo Fontalvo-Buelvas, María Teresa Pulido Silva, Miguel Ángel Escalona Aguilar, Raúl Romero Ramírez · Memorias · Mexico (Xalapa)

This diachronic study analyzed the drivers and inhibitors of urban agriculture in Xalapa, Mexico, through a historical tracing from 1821 to 2023. Drivers included rural immigration, academia, and government programs, while inhibitors were identified as diversification of trades, ejido laws, remittances, health policies, and food markets.

Mar Loren-Méndez, Celia Chacón-Carretón, Pablo Manuel Millán Millán · ACE Arquitectura Ciudad y Entorno · Spain (Málaga)

This study examines the urban dimension of agricultural heritage, specifically urban orchards, in cities where agrarian activity is deeply intertwined with their origin and evolution. Using Nerja, Málaga, Spain, as a case study, the research highlights that accelerated urban transformation in recent decades has led to a rupture, undermining agrarian logic by abandoning historical growth practices. The study emphasizes the fundamental role of agrarian activity in built environments and advocates for the protection of urban orchards.

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.

Gideon Baffoe, Philip Antwi‐Agyei · City and Environment Interactions · Ghana (Accra)

This mixed-methods study analyzed the role of urban agriculture (UA) in climate resilience in Accra, Ghana, from the perspective of policymakers. While UA contributes to food security, water use efficiency, and ecological protection, its integration into policy frameworks was found to be limited due to challenges such as weak institutional coordination, competing economic priorities, and governance inefficiencies.

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.

Kurnia Dewi, Yusuf Hariyoko, Hasan Ismail · Presidensial · Indonesia (Surabaya)

A qualitative descriptive study investigated stakeholder synergy in urban farming programs in Surabaya, Indonesia. Data was collected through interviews, documentation, and observation involving the DKPP, agricultural extension officers, farmer groups, and the local community. Strong commitment, competence, awareness, and continuity were identified as driving factors for successful implementation, but challenges include declining active farmer groups and limited facilities.

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.

Abdul-Salam Ibrahim, Marney E. Isaac, Thembela Kepe · Land Use Policy · Ghana

Focusing on Ghana, where floods driven by urbanization and climate change are destabilizing urban systems in which land tenure is integral, this study drew on political ecology and land-tenure-security frameworks to examine how floods affect the land tenure security of flood victims. Based on semi-structured interviews with flood victims and planning officials, it found that flood-induced rezoning and new planning schemes, tenant insecurity, relocation, loss of land documents, and threats to urban agriculture all affect flood victims' land tenure security; possessing land documents was found to be important for tenure security but not an absolute condition for victims' perceived security. Post-flood land-use planning for flood risk management was found to have dual potential — it can enhance tenure security and bolster community resilience, but when carried out in an exclusionary way that overlooks the urban poor, it can instead perpetuate inequality and tenure insecurity. The study recommends tenure-responsive land-use planning that embeds contextual, procedural, and distributive equity principles into planning responses to urban floods.

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.

Edwin Javier Ortega Zúñiga · Ediciones Comunicación Científica eBooks · Colombia

A study of Palmira, Colombia — a city with a long tradition as the country's agricultural capital — finds that it nonetheless faces significant food insecurity. Prior research reviewed in the study attributes this to an aging rural population and young people's declining interest in farming (which has shrunk the available labor force and limited adoption of new technology), gender inequality that restricts women's access to agricultural resources and decisions, climate change impacts such as droughts and floods on production, and accelerated urbanization that has reduced cropland and fragmented the agricultural landscape. As a potential response, the study describes a pilot project at four sites in the city that installed small-space vegetable production systems, which it reports functioned as a viable source of fresh food in dense urban settings. The authors call for a multidisciplinary approach combining social, economic and environmental factors to address food insecurity in Palmira.

Jacob Wallace · Waste Dive · United States

NYC's Department of Sanitation began enforcing mandatory curbside organics separation on April 1, 2025, issuing nearly 2,000 summonses in the first week, but Mayor Adams paused broad enforcement through 2025 on April 18, limiting fines to persistent violators. The city had distributed about 190,000 free bins and sold 63,000 more, and organics diversion had risen 65% from FY2022 to FY2024.

Consell de la Generalitat Valenciana · Diari Oficial de la Generalitat Valenciana (DOGV) / BOE · Spain

A decree-law issued by the Consell (Valencian regional government) on 4 February 2025, published 5 February 2025, amending the 2018 Huerta law and its implementing plan (Decreto 219/2018) to simplify administrative procedures for reconstruction following the 29 October 2024 DANA flooding. It abolishes the Huerta Council and chapters on agrarian development planning and farm inventories, and relaxes urban-planning parameters for agricultural buildings.

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.

Zhe Zhu, Faith Ka Shun Chan, Gang Li, Mengxia Xu, Meili Feng, Yong‐Guan Zhu · Soil & Environmental Health · China

This review examines urban agriculture in China, identifying three forms: small-scale, capital-intensive, and tourism-type, each with benefits and challenges shaped by local context and government policies. Despite benefits like improved community cohesion and environmental sustainability, urban agriculture in China faces significant limitations including land availability, capital shortage, market access, and insufficient governmental support. Strategies and four recommendations are proposed to address these challenges.

Neşe Börü · International Journal of Leadership in Education · Turkey

This case study investigated school principals' practices and barriers to sustainable development in Turkish K-12 schools under centralized management, using semi-structured interviews. The findings highlighted the need for leadership skills, collaboration with external bodies, public education, reward systems, and school budgets under a centralized management approach. The research identified that the centralized management system itself presents a barrier to sustainable development efforts in these schools.
