Workshops critically experimented with the possibilities and challenges of blockchain as an infrastructure for food abundance and reparative work, using fictional scenarios set in a London transformed into a city farm by 2025. This experimentation suggested that blockchain presents challenges to such restorative and sustainable work. For participants, reparation involved working in the aftermath of social and environmental collapse to bring into being more-than-human-value systems that radically decentered human knowledge and experience.

This research surveyed federal and state urban agriculture (UA) laws in Brazil to analyze their implications for urban planning (UP). Findings indicate that despite an increase in approved laws, there is no articulated national policy, laws vaguely address UA's interfaces with UP, and they do not objectively tackle territorial challenges faced by UA.

Sandrine Simon · Urban Governance · Portugal (Lisbon)

This study examined urban agricultural initiatives in Lisbon, Portugal, and their integration into urban planning strategies for sustainability, using Design Thinking methodology for a literature review. The integration of urban agriculture into urban planning is identified as a complex problem due to conflicting goals among actors. The research suggests that Design Thinking could assist urban planners in addressing this challenge by providing flexible, iterative, and participatory approaches.

A critical literature review discussed the evolution of food and nutrition security (FNS) and the contributions of urban and peri-urban agriculture (UPA). The review found that institutional responses to FNS are concentrated in times of crisis, which favors the maintenance of globalized and unsustainable food systems. UPA practices show peaks of rise and decline, evolving with the FNS agenda.

Xin Mai, Yueli Xu, Yungang Liu · Annals of the American Association of Geographers · China (Shanghai)

This study investigated the emergence and development of two flagship community garden cases in Shanghai, China, initiated in 2016. Observations revealed that a nonprofit organization, not local citizens or municipal government, proactively advanced community garden production and participation. The community garden phenomenon was found to reify an alternative subjectivity, emphasizing social organizations as a state "flanking mechanism" for extraeconomic urban governance objectives.

Runrid Fox-Kämper, Caitlin K. Kirby, Kathrin Specht, Nevin Cohen, Rositsa T. Ilieva, Silvio Caputo, Victoria Schoen, Jason K. Hawes, Lidia Poniży, Béatrice Bechet · Landscape and Urban Planning · Europe; United States

The relationship between urban agriculture (UA) and food-energy-water (FEW) nexus policies was analyzed using policy data from five case study cities in Europe and the U.S. (Dortmund, Gorzów Wielkopolski, London, Nantes, and New York City). An analysis of 78 policy documents and a Q-sort ranking by UA policy experts showed that the number, type, and degree of support for nexus policies varied among cities, and few policies (19) incorporated all elements of the nexus. Regulations were considered more effective at ensuring resource-efficient UA than incentives or awareness-raising policies.

This exploratory review study examined the viability of urban food systems and their governance in Venezuela, based on secondary sources. While identifying available resources like educational infrastructure and a renewed legal framework, the study highlighted significant limitations. These include increasing deforestation, deteriorating potable water services for urban agriculture, migration of skilled populations, decline in public funding for science and technology, opaque official information, and scarcity of financing for new developments.

Mallika Sardeshpande, Charlie M. Shackleton · People and Nature · South Africa

This study interviewed 80 urban foragers in four cities in South Africa's eastern coastal region to understand urban foraging in a developing nation context. Foragers began foraging in childhood, viewing it as a cultural and recreational activity, but formal green spaces were not used for foraging and were perceived as poorly provisioned in urban planning. This indicates a lack of governance in urban planning regarding foraging.

This mixed-methods study examined 34 urban community gardens in Cape Town, South Africa, to assess their capacity to function as urban commons across six areas: infrastructure, inputs, land, produce, labour, and immaterial components. Findings demonstrated that while these gardens counter neoliberal privatization and individualization, their capacity to function as urban commons is significantly curtailed by their entrenchment within the neoliberal context.

Benjamin Schrager, Hiroki Ikeda, Takahashi Yukitsugu · Journal of Agriculture Food Systems and Community Development · Japan

This article explores Utsunomiya University’s Eco-programs, which combine a pesticide-free community garden with an educational series, using ethnographic data. Findings indicate tensions between the Eco-programs' agroecological goals and other institutional goals at the university. Despite these conflicts, the programs provide a space for agroecological gardening and serve as an example of an alternative agricultural initiative in Japan.

Susana Alves, Bahar Bașer Kalyoncuoğlu · Ecopsychology · Turkey (Istanbul)

This study explored the socio-ecological potential of urban agriculture in 10 family-related projects in Istanbul, where Bostans (historical urban vegetable gardens) are culturally significant. Despite their importance and UNESCO recognition, the planning and management of bostans have been hampered by rapid urbanization and a lack of integrative policies. Data from interviews, observations, and fieldwork highlighted the role of kinship in knowledge transfer and how farmers base activities on past-present affordances and future expectations.

Simon Marvin, Lauren Rickards, Jonathan Rutherford · Urban Studies · Global

This paper critically examines urban controlled environment agriculture (CEA), reconceptualizing it as an emergent urban infrastructure for artificial, highly productive microclimates. It argues that CEA attempts to secure food production through three spatial-temporal fixes: enclosing food production indoors, moving it closer to cities, and integrating it into city buildings, thereby extending existing agricultural logics. The paper identifies future research challenges for urban studies regarding CEA.

A systematic review of urban agriculture (UA) case studies identified conditions enabling and constraining UA development across different country income groups. For high-income countries, a lack of farmers' knowledge and urban development are significant challenges to UA implementation. Common requirements for all income levels include motivation, labor, policy, social capital, and arable land.

Agnes Naipospos, Raia Azzura · Journal of Sustainable Development and Regulatory Issues (JSDERI) · Indonesia

Indonesia faces a reduction in vegetable supply due to rapid urban development, and urban farming can be a solution to meet food needs, reduce household expenses, and increase farmer income. Using a normative juridical approach, this study indicates that Indonesia needs an urban farming program, but its current implementation is not optimal. Therefore, the Indonesia Masterplan for Future Urban Farming (IM-for-FUF) is introduced as an innovation expected to better support the implementation of the green economy.

This review analyzed opportunities and constraints for creating edible cities and accessing wholesome functional foods sustainably. While urban food production methods like controlled-environment farms and home gardens exist, significant constraints include pollution, a lack of government support, and economic challenges for urban farms. These issues must be resolved for edible cities to become widespread.

Nehiby Alcántara Nieves, Rosa María Larroa Torres · Iztapalapa(en línea)/Iztapalapa · Mexico (Mexico City)

This article identified agroecological practices in 10 urban gardens (hu) in Mexico City and their relationship with the construction of food citizenship. Data was collected through interviews with garden managers and users, and participant observation. The study found a tendency to prioritize responsibilities over rights within these urban gardens.

Gareth Haysom, Jane Battersby · Palgrave studies in agricultural economics and food policy · Africa

Based on findings from cities in five African countries, this study argues for a re-framing of urban food system resilience. It contends that the urban system, specifically infrastructure, shapes the functioning of the food system and consumers' ability to use it, and that the agency of urban food system users needs inclusion in understandings of, and efforts to increase, food systems resilience.

Imelda Cahiles, Ricardo Bullecer · ACADEME University of Bohol Graduate School and Professional Studies · Asia

A study assessing the implementation of the Gulayan sa Paaralan Program (GPP) in schools in Lila District, Bohol, Philippines, revealed that the overall program implementation was less implemented. While roles and responsibilities at the school level and the establishment and maintenance of school gardens were implemented to a moderate extent, capability building, program monitoring, sustainability mechanisms, and program evaluation were less implemented. Respondents generally perceived the program as moderately beneficial and reported that implementation-related problems were less serious.

This bibliographical and documentary research analyzed the effectiveness of public food security policies in Brazil between 2012 and 2022, also considering urban agriculture as an alternative. It concluded that public policies were gradually weakened, and from 2019 to 2022, the Brazilian government discouraged food policy implementation. Consequently, Brazil faces food insecurity and hunger due to disjointed policies, the pandemic, and an economic crisis.

Following the PRISMA protocol, a 2023 systematic review evaluated 26 studies on the interplay between urban agriculture (UA) and sustainability surveyed on Web of Science. While UA is increasingly recognized as an action to promote urban sustainability and inform public health policy for urban populations, the review confirms that its implementation still presents challenges in countries across both the Global North and Global South. The review identified numerous key challenges to UA adoption, including air and soil contamination, availability of green areas, layout of urban infrastructure, and food distribution, among others. Given the many socio-economic and environmental contextual factors involved — especially when comparing Global North and Global South realities — the review concludes there is a need to develop a model adaptable to these different contexts. It further concludes that the concept of sustainability lacks a universal understanding, and that one of the most important remaining gaps is addressing social issues in relation to environmental ones.

Mahir Yazar, Ece Baykal Fide, İrem Daloğlu Çetinkaya · Journal of Environmental Policy & Planning · Turkey

A 2023 study of climate policies in nine cities in Turkey examined how vulnerable groups and individuals are identified and how land-use policy is developed to address the identified vulnerabilities and climate justice concerns, using policy content analysis and expert interviews. The analysis found critical relationships between identified vulnerable groups, responsive land-use policy and climate justice. While social-aid municipalism-related vulnerabilities dominated districts' climate policies, nature-based solutions (NBS) — especially green infrastructure and urban agriculture — emerged as the dominant climate adaptation approach. However, the way urban vulnerabilities are prioritized in the climate and sustainability plans places less emphasis on intersectionality and infrastructure-related vulnerabilities, and tokenism of justice occurs in the policy documents: the plans do not incorporate vulnerable communities into land-use planning. The study concludes that the complexity of responsive land-use policy requires greater awareness of how to practically support vulnerable communities.

This paper analyzes the functions of urban and peri-urban agriculture (UPA) as a strategy for sustainable and resilient urban food systems and for coping with global emergencies. It identifies various functions of UPA and how they connect, but also discusses obstacles to its large-scale implementation. The paper highlights that despite its potential, significant barriers hinder UPA's widespread adoption.

This study compared 19 municipal urban home food gardening programs in Canada in 2020, which provided free gardening supplies and instructions. It found a complicated relationship between municipalities, gardening programs, and food security, and determined that gardening somewhat alleviated social and emotional challenges from the COVID-19 pandemic. However, municipalities are limited in their policy capacities to adequately address food insecurity in Canada.

Betty Mntambo · Huria Journal of the Open University of Tanzania · Tanzania (Morogoro Municipality)

This study examined land tenure security in urban agriculture among 69 male and female vegetable farmers in Morogoro Municipality, Tanzania, using snowball sampling and a cross-sectional design. Findings revealed that farmers access land informally by renting from legal landowners, with social relationships determining tenure security. Land tenure insecurity negatively affects vegetable cultivation and generates uncertainty and animosity between farmers and landlords.
