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.

This study investigated the quantity, composition, and disposal practices of domestic waste in Bukavu City, Eastern D.R. Congo. Findings revealed significant challenges in waste management infrastructure and practices, showing that approximately 5% of waste undergoes composting, while 10% is used as livestock feed, 66% incinerated, and 17% buried. Waste management is primarily handled by children (82%), with very limited involvement from non-governmental organizations.

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.

Ángeles Donoso Macaya, Kendra Sullivan · · United States (New York City)

This chapter explores the experiences of co-authors in the "Archives in Common (AiC)" project, which aimed to strengthen public humanities infrastructure within and beyond CUNY’s Graduate Center. Conducted across three locations in New York City, the project highlighted institutional norms that fail to adequately support community-led research practices or acknowledge and reward diverse expertise.

Amélie André · · United Kingdom

This case study of Letchworth Garden City examined the interplay between the town's layout, social practices, and governance supporting a local sustainable food economy. Food mapping and an ethnographical approach showed how Letchworth's masterplan provides a backbone for alternative food infrastructure, though the edible landscape is not always visible or effective for residents. Discussions with experts also pointed to a gap in coordination among key local stakeholders, which would be beneficial for improving the local urban food strategy.

Ann-Kristin Steines, Michele D’Ostuni, Anna Wissman, Kathrin Specht, Chiara Iodice, Runrid Fox-Kämper, Francesco Monticone, Isabella Righini, Véronique Saint-Gès, Antonella Samoggia, Francesco Orsini · Cities · Europe

This research addressed international and national policies, as well as related constraints and challenges affecting City Region Food System (CRFS) development in six European countries. Data was collected through desktop research, stakeholder interviews, and a workshop. The study found that planning laws restrict possibilities for food production in cities, and legal frameworks prevent the marketing and sale of food produced by non-commercial actors or informal farmers. It also identified a need to expand vocational training in the agricultural sector.

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.

Orathai Paiyarat, Uthaithip Jiawiwatkul · International Journal of Urban Sustainable Development · Thailand

This qualitative study examined the development process, results, and influencing factors of the Hat Yai urban agricultural network for food security in Hat Yai City, Songkhla Province, Thailand. Data was collected from 31 participants through participant observation, in-depth interviews, and group discussions. The study identified a three-stage development process: network formation, seeking cooperation, and learning and integration, with results reflected at individual, group, and network levels linked to sustainable development. Negative factors affecting the development process included the nature of Hat Yai urban residents in a developing country context, resource inadequacy, and public policy.

Sarah Buzogany, Abby Cocke, Holly Freishtat, Yeeli Mui, Mariya Strauss, Sylvia Kelly · Urban agriculture · United States (Baltimore)

Baltimore, United States, has developed urban agriculture policies over the last decade, integrating them into a food systems approach to sustainability. Policy development covered zoning, permitting, land leasing, and soil regulations. However, challenges were encountered regarding staffing, funding, resident engagement, and differing city agency priorities, especially concerning land access. The experience highlights the importance of mainstreaming food policy into urban planning.

M. S. (Muhammad ) Ramadhan, R. (Renny) Nurhasana · Neliti · Indonesia (Jakarta)

This qualitative case study in East Jakarta, Indonesia, investigated urban farming as a means to balance urban life. Field observations, interviews, and documentation identified several obstacles: a lack of community awareness, limited facilities, and challenges from extreme weather. Proposed solutions include community empowerment, improved facilities, and better climate control and supply chain systems.

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.

Emmanuel Olatunbosun Benjamin, Abiola Adegoke, Gertrud Buchenrieder · Land · Nigeria (Lagos)

This exploratory qualitative research, conducted in Lagos, Nigeria, used focus group discussions to compare the perspectives of private urban farmers and public sector representatives on innovative urban farming. Urban farmers identified a lack of public sector support for circular agri-food technologies, while public sector representatives attributed issues to farmers' behavioral and educational shortcomings, including poor coordination. These differing views highlight complex dynamics and a need for structural changes and stakeholder dialogues to develop effective urban farming policies in Sub-Saharan Africa.

Paula Mota Santos · Social Inclusion · Portugal (Porto)

Grassroots urban horticultural plots (hortas) in the Porto Metropolitan Area, Northern Portugal, are informal communities that have existed for decades, often involving over 20-30 people. However, these low-income urbanite horticultural communities are not cherished by city governance, which does not prevent their destruction. This incompatibility between urban governance and grassroots communities hinders the right to the city for the low-income urbanites who created them.

This study examined the governance of irrigated urban agriculture in Arusha, Tanzania, and Khulna, Bangladesh, from a service regime perspective. Findings showed how service regimes bridge the gap between formal governance institutions and practices around irrigated urban agriculture. It is concluded that acknowledging, facilitating, and aligning these regimes can strengthen governance arrangements.

Market gardening in Kinshasa's urban and peri-urban areas faces multiple constraints, including land insecurity, low natural soil fertility, the incidence of diseases and pests, weak technical support, climate hazards, poor input supply, and problematic marketing systems. These constraints limit yields in production sites and hinder the development of market gardening activities.

Delf Rothe · Political Geography · United States (New York City)

This paper critically examines the concept of "green resilience" through a case study of various green resilience projects in New York City, including survivor trees, memorial groves, and community gardens. The study argues that these spaces function as key forms of state rule and biopolitical power, identifying three tensions or contradictions of green resilience as a form of biopolitical government: visibility and invisibility, knowledge and ignorance, and control and emergence.

Matthew L. Richardson, John Taylor, Megan J. Thompson, Anusuya Rangarajan, Mamatha Hanumappa, Neith G. Little · PLoS ONE · United States (Northeastern United States)

This online survey of 394 urban growers, primarily in the Northeastern United States, profiled growers and assessed urban agriculture's state, identifying needs and challenges. Most growers were white (non-Hispanic), under 45, well-educated but without agriculture degrees. Urban agriculture was dominated by small non-profits and home/community gardens. A critical finding is that urban growers face diverse barriers, with the most common being land availability and long-term access in urban areas, and many reported low revenue or operating at a net loss.

This essay shares two research practices stemming from the author's seven-year engagement with extractive supply chains for specific objects. Swale is a floating food forest that uses the common law of the waterways as a loophole to do what was illegal on common land, highlighting governance challenges within existing systems.

This article analyzes the recalibration of justice for agrarian communities along the Yamuna in Delhi. Following a 2015 ban on edible crop farming by India's apex environmental court, the Delhi Development Authority has conducted multiple demolition drives for nearly a decade to evict farmers and clear land for redevelopment. The ongoing contentions involving farmers, planning agencies, and the judiciary in this region are symptomatic of the erosion of social justice in urbanizing India.

This bibliographic review identified the main problems of urban agriculture and actions for sustainability. The study found that the primary deficiencies in urban agriculture are inadequate management practices, a lack of organization, and absent or inefficient public policies. Key leverage points for change include agroecology, policies for land access and sustainable financing, and dissemination processes.

Andrea Baier, Christa Müller, Karin Werner · Neue Ökologie · Global

This study discussed the significance of the new urban garden movement for sustainable urban restructuring, focusing on community garden practices over the past two decades. It examined how the movement is integrated into the governance of urban climate crisis policies, how it utilizes this framework, and to what extent the autonomy of gardens as free spaces and commons can be maintained under these circumstances. The findings suggest that the autonomy of urban gardens may be difficult to maintain when integrated into climate crisis policy governance.

This paper presents a methodology applicable to sustainable community actions, developed from seven years of experience with low-income communities in a Brazilian community garden. The methodology is based on participatory action research, systemic design, agroecology, food sovereignty, and solidarity economy principles. The study demonstrates the importance of integrated work among the elements of the quintuple helix model (society, government, industry, academia, and environment), but it does not detail specific challenges or limitations regarding governance.

This chapter examines the dominant convention in critical agrarian studies and agrarian movements — that land struggles are best captured by an agrarian-reform framework of expropriating land from large private monopolies for redistribution to landless and near-landless working classes. It argues that while this type of struggle remains important, it does not fully capture the range of land struggles of working people across rural and urban, agricultural and nonagricultural spaces. Over recent decades the working classes have fragmented, as the numbers of people combining agricultural/nonagricultural and rural/urban livelihoods have vastly expanded, decentering working people's land struggles from the classical treatment tied to agriculture and capitalism. Land struggles today are dispersed and multisited, with political leadership and power that are polycentric rather than unified, and span multiple scales.

In New Jersey, 50 food desert areas face the most severe food insecurity across both rural and urban contexts. This study identified nine barriers to implementing urban agriculture initiatives in New Jersey's urban food deserts, using a sequential quantitative analysis combining a survey of food systems professionals with a GIS-based spatial analysis to identify the most prevalent barrier. Working in partnership with New Jersey urban agricultural organizations, the study found that lack of funding was the most commonly cited barrier to expanding urban agriculture initiatives. The GIS-based spatial analysis found that high-priority barriers varied by region, but that all organizations identified funding, or lack of access to funding, as a significant barrier regardless of whether they operated in a low- or high-income neighborhood. The study concludes that policymakers must reevaluate the role of urban agricultural organizations in New Jersey's urban food deserts.

This book chapter combines bibliographical and topical analysis of scholarly and gray literature with case studies from Middle East and North Africa (MENA) countries to examine the state of urban and peri-urban agriculture (UPA) amid regional climate pressures — rising temperatures and frequent droughts damaging limited water resources and threatening agriculture and food security. The chapter reports that UPA in the region lacks adequate infrastructure and resources, including access to water, suitable land and equipment, and that in many MENA cities, the absence of government initiatives combined with land tenure problems and high land prices makes UPA less prevalent and less viable; it concludes that improved policy support and enabling regulations — including zoning rules and financial and technical support — are needed to expand UPA in the region.
