A ten-month non-experimental study at the "Pueblo Griffo Viejo" organic farm in Cienfuegos, Cuba, identified limiting factors in vegetable production through surveys, field observations, and documentary review. The research found low yields due to poor substrate quality, inadequate water management, limited organic matter, and insufficient training participation. Additionally, the workforce's low educational level hindered efficient agricultural practices.

Michaela Pixová, Christina Plank · Environmental Sociology · Czechia (Prague, Brno)

This paper compared the roles of allotment and community gardens in urban sustainability, using Prague and Brno, Czechia, as case studies. It analyzed perceptions of both by municipal actors, gardeners, and activists across four dimensions: public access to urban greenery, community building, food cultivation, and environment/climate protection. The paper argues that governments' preference for gardens aligned with the status quo undermines citizens' right to the city, urban sustainability, and resilience against future threats.

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.

Christian Kofi Sarpong, Romanus Dogkubong Dinye, Alex Donbeinaa, Vera Nyarko Amoako · Asian Journal of Agricultural and Horticultural Research · Ghana

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.

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.

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.

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.

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.

Anila Kausar, Viola Vambol, Sergij Vambol, Saima Sultana Sharfi · International Journal of Economic and Environmental Geology · Pakistan (Karachi)

This study conducted a Land Use Land Cover (LULC) analysis of Murad Memon Goth, a peri-urban area of Karachi, Pakistan, comparing data from 2013 and 2021. The results revealed a 9.6% increase in settlement sprawl, indicating significant encroachment on agricultural lands. Cropland area decreased from 38.86% in 2013 to 26.11% in 2021, highlighting a negative trend for peri-urban agriculture in the region.

Beata Sirowy, Deni Ruggeri · ˜The œGeojournal library · Global

This chapter reflects on urban agriculture practices in public spaces, emphasizing their unique role in the individual and communal well-being of city dwellers. It concludes with a brief reflection on the future trajectories for urban agriculture practices in compact cities.

Cecil C. Konijnendijk · Edward Elgar Publishing eBooks · Global

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.

Matthijs T. Wessels, Gert Jan Veldwisch, B.J.M. van Vliet, Alphonce Kyessi, Shaaban M. Mgana · Water International · Tanzania (Dar es Salaam)

This study examined the policy dynamics of irrigated urban agriculture in Dar es Salaam, Tanzania, using stakeholder interviews and a literature review. It found that while irrigated urban agriculture is positively received for its productivity, it faces challenges from discourses prioritizing health and modernity. Authorities pursue modern farming models, but most urban farmers operate with informal and insecure access to land and water, highlighting a tension between planning ideals and urban reality.

Meriem Korchi, Ouassila Bendjaballah · Indonesian Journal of Social Science Research · Algeria

This study assessed urban actors' perspectives on urban agriculture in Annaba, Algeria, and mapped agricultural activities to integrate them into urban policy. Interviews with decision-makers and farmers, combined with spatial analysis, revealed that while there is interest in urban agriculture, it is not effectively integrated into institutional and legal frameworks. Agricultural plots in cities are often reserved for future urban development.

Nour Alkhaja, Khaled Alawadi, Kholoud Almemari, Ghalya Alshehhi · Progress in Planning · Global

This literature review of 51 articles examines how urban agriculture (UA) is practiced, institutionalized, and sustained, focusing on governance. It identifies consistent challenges such as discord between civil and municipal actors, contextual factors hindering supportive policies, and urban densification encroaching on UA land. These issues lead to informal or constrained UA practices and tenure insecurity.

Lesli Hoey · Urban agriculture · Global

This paper highlights that urban agriculture (UA) serves as a vital lifeline for food and income security for many urban growers in the Global South. However, it notes that many governments in the Global South actively resist UA in the name of "modernization," and by promoting supermarkets and restricting informal food markets, they potentially undermine the positive impacts of UA on urban food security and poverty.

Paula Restrepo · · Colombia (Medellín)

As part of the Red de Huerteros Medellín (RHM) collective, urban agriculture in Medellín was mapped to identify its features and problems. A main problem found was a poor or non-existent connection between urban farmers and key organizations like seed keepers. Few urban farmers had knowledge about the ecopolitical implications of the seed business, and even fewer obtained seeds from seed keepers or showed consideration for their labor.

Melikenur Kalfaoğlu, Hasan Hüseyin Aksu · Shanlax International Journal of Education · Global

This qualitative case study explored the opinions of 27 mathematics teachers in MoNE secondary schools regarding the use of school gardens in lessons during the 2023-2024 academic year. Teachers generally supported using school gardens but reported facing problems with maintaining discipline, attracting student attention, and scheduling conflicts.

Waseem Ahmed Khattak · International Assulta of Research and Engagement (IARE) · Pakistan

"Go Green communities" in Pakistan were studied as grassroots movements promoting environmental awareness and sustainable practices. Using a Participatory Action Research (PAR) approach, activities included waste management, urban gardening, and policy advocacy. The initiative demonstrated increased community involvement in eco-friendly efforts, leading to tangible outcomes such as waste segregation systems and enhanced green spaces. However, challenges including financial limitations, resistance from industries, and restricted access to green technologies highlighted the need for stronger institutional support.

Arild Eriksen, Deni Ruggeri, Esben Slaatrem Titland · ˜The œGeojournal library · Norway (Oslo)

This essay discusses the motivations for co-creating urban agriculture in public spaces from the perspective of an architect and urban farmer/beekeeper practicing bottom-up, participatory design in Oslo. It critiques the current aesthetics of impermanence and temporality in urban agriculture and questions the idea that the joy and freedom it brings should be enhanced by future development and policy. The essay presents a rich collection of stories about regeneration, change, and collective action and cultivation, rather than a replicable model.

Juan Camilo Fontalvo-Buelvas, María Teresa Pulido Silva, Miguel Ángel Escalona Aguilar · Bitácora Urbano Territorial · Global

A bibliographic review identified that the main deficiencies in urban agriculture are inadequate management practices, a lack of organization, and absent or inefficient public policies. The study suggests that agroecology as a management system, policies for land access and sustainable financing, and dissemination processes are key leverage points for driving urban agriculture towards sustainability.

Chiara Tornaghi · ˜The œGeojournal library · Global

This chapter, based on 15 years of research, discusses key issues hindering urban agriculture from reaching its full potential for human and non-human health. It highlights shortcomings in urban planning policy, specifically the failure to recognize urban agriculture as food production, the invisibility of soil and lack of understanding of living soils, and the disregard for the advisory role of soil care and food production specialists in public land design and soil management. The chapter suggests that agroecological considerations can deepen urban agriculture's ambition in public spaces.

Nordregio, Luciane Aguiar Borges, Ana de Jesus · · Global

This report discusses the barriers and drivers of Urban Agriculture (UA) within the framework of the Horizon 2020 project 'SiEUGreen,' across environmental, technological, economic, social/cultural, and regulatory/institutional aspects. Based on insights from five showcases in Norway, Denmark, Turkey, and China, the results suggest that city food provision and UA systems can be designed considering circular economy regenerative cycles. However, key barriers limiting UA uptake include the need for more evidence-based research, further experimentation for innovative technological developments, high investments, difficulties accessing financial support, underdeveloped business cases, limited recognition of UA's benefits, and behavioral/cultural barriers.

Moye Eric Kongnso · International Journal of Environment Agriculture and Biotechnology · Cameroon

A mixed-methods study in the West Region, Cameroon, examined compost use in urban farming through 265 household surveys, 11 in-depth interviews, and one focus group. While compost availability and technical assistance favor its use, small-scale farmers face significant technical, knowledge, financial, institutional, and policy constraints. State extension services prioritize mineral fertilizers over compost, and the current regulatory framework does not encourage compost use, leading to the persistence of traditional practices.
