This chapter documents the growth of charitable non-governmental responses to food insecurity in Canada and the UK, including food banks and community gardens. It argues that these responses are problematic because they fail to address the economic and political causes of food insecurity. Further failures include the stigma experienced by food bank users and the false belief that food insecurity is being resolved.

A study analyzed the challenge faced by community urban gardens in Madrid, Spain, in remaining transformative spaces amidst an ecossocial crisis. These gardens are initiatives situated between community and public institutional management, with their expansion and institutionalization involving practices and relationships among diverse agents. The study points out the difficulty for these gardens to maintain their transformative role—updating community ties, reciprocity, and mutual care, and reformulating relationships with "nature" in the city and food supply—without being absorbed by market logics or marginalized into welfare or community volunteering spaces.

Hilary Jasmin · Evidence Based Library and Information Practice · United States and Canada

This study surveyed 58 academic and public libraries in the United States and Canada regarding their seed lending programs' goals and marketing, using an online survey. While some libraries stated intentions related to food justice and activism, their marketing and programming primarily focused on neutral gardening and how-to classes. The findings reveal a gap between the initial, less neutral intentions and the more neutral, less activist programming language used for seed libraries.

Yusuf Kamaluddeen Ibrahim, Zabawi Abdul Ghani, Rasheed Osuolale Oladosu, O. D. Idris,, Tamwesigire Caleb · Journal of Innovative Research · Nigeria (Bauchi)

In Bauchi metropolis, Nigeria, urban farming practices and constraints were investigated among 285 urban farmers. Findings revealed that most farmers do not own land, instead borrowing or renting it. The major constraints to urban agriculture were reported as lack of tenure security, limited land area, and poor access to microcredit facilities.

Odeimy Sarría-Crespo, Mayelin López-Roque, Wilfredo Sis-Sánchez · Revista Metropolitana de Ciencias Aplicadas · Cuba (Cienfuegos)

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.

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.

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.

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.

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.

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.

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.

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.

Ashagrie Gibtan, Wondwosen Abera, Mekuria Delelegn, Molla Maru, Adamu Emiru · Ochrana prírody Slovenska/Ekológia · Ethiopia

Land Use/Land Cover (LULC) dynamics were analyzed in four Ethiopian cities—Addis Ababa, Hawassa, Bahir Dar, and Adama—over 17 years from 2006 to 2022. SPOT 5 and Sentinel satellite imagery, key informant interviews, focus group discussions, and field observations were used. Findings revealed a rapid expansion of urban built-up areas, primarily at the expense of peri-urban horticultural lands, which has an adverse impact on the sustainability of urban agriculture.

Barbara Maćkiewicz, Paulina Jeziorek · Przegląd Geograficzny · Poland

A two-case study in Warsaw and Poznań, Poland, explored the relationship between community gardens and cultural institutions, identifying factors that promote and impede their functioning. The study found that these gardens are characterized by a changing governance model, shifting towards a top-down approach where community members lack influence on strategic decisions. The involvement of cultural institutions, while facilitating longevity, may simultaneously disempower the gardens' viability.

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.

A systematic review and bibliometric analysis examined the implications of climate-smart agriculture (CSA) practices and climate adaptation strategies for food and income security in urban Sub-Saharan Africa. The review found that CSA practices boost urban food production and income, but also recognized critical challenges and trade-offs requiring urban agriculture transformation.

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.

Jeffrey Chiwuikem Chiaka, Gengyuan Liu, Hui Li, Wen Zhang, Mingwan Wu, Zhaoman Huo, F. Gonella · Environmental and Sustainability Indicators · Sub-Saharan Africa

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.
