This paper discusses rooftop gardens as an alternative for vegetable production in Bhubaneswar City, India. While rooftop agriculture can improve ecosystem services and enhance urban biodiversity, vegetable production activities on rooftops are limited due to multiple challenges that need to be addressed for widespread implementation. Rooftops are not a total solution for food security but can supplement other urban food sources.

Salvatore Engel‐Di Mauro, George Martin · · Global

Claims that urban food production raises food security and creates a more just society are questionable and contradicted by data from the Global North. Urban land is insufficient, sunlight is often inadequate, and soil pollution is widespread. Technological attempts like vertical and rooftop farming have limited feasibility, may worsen environmental and social problems, and do not address major food sources, access, or waste. Furthermore, urban gardens are increasingly linked with socially devastating gentrification.

Leigh Whittinghill, Sait Sarr · Urban Science · United States (Louisville, Kentucky)

A survey of 40 urban farmers and gardeners in Louisville, Kentucky, assessed their agricultural practices and barriers. Most growers engaged in urban agriculture for non-commercial reasons, with only 11% operating for profit, and smaller farms were less likely to be profitable or certified. Common sustainable practices included composting (60%) and crop rotation (54%), while challenges involved limited space, farm certification access, pests, and lack of record-keeping.

Ana Poštek, Ivica Kisić, Marija Cerjak, Luka Brezinščak · Journal of Central European Agriculture · Croatia

This paper analyzes various social aspects of urban agriculture and presents examples from Croatia where social benefits are the primary purpose. Urban agriculture can have social effects such as fostering activism, gender equality, social cohesion and inclusion, education, and cultural heritage preservation. However, policymakers struggle to implement urban agriculture within city planning.

Christina Ergas · · United States

This chapter explores urban ecovillages in the United States, highlighting challenges faced by ecovillagers in a neoliberal context. It examines cultural conflicts between sustainability and consumer culture, and points out the exclusive, upper-class, white nature of the local food movement in the US. Monetary and time constraints have made local organic food an elite phenomenon, often cited as a first step to gentrification in urban communities.

Ramón Antonio Mosquera Mena, Yolvi Prada Millán · Universidad Nacional Abierta y a Distancia eBooks · Colombia

Urban and peri-urban agriculture in Colombia offers benefits such as alleviating food insecurity and creating jobs, but currently lacks government policies to support these processes. This paper contextualizes relevant experiences and technical tools for implementing agroecological orchards, emphasizing environmental and social sensitivity. It also notes that agricultural research in Colombia is still emerging, requiring more applied research for technological development to benefit communities and farmers.

This qualitative study examines the implementation of urban farming in Bandung City, Indonesia, from a political ecology perspective, focusing on market, service, and institutional interactions, and product marketing chains. The research identifies policy failures, where city government agricultural policies were insufficient to meet residents' food needs, necessitating top-down urban farming innovations. It also notes market failures due to public dissatisfaction with available products, driving bottom-up urban farming initiatives by independent organizations. Funding sources and operational cost efficiency strategies differ between government-led and independent urban farming efforts.

This study utilized the 'sustainable innovation journeys' concept to trace urban food initiatives in Rotterdam (Netherlands), Vigo (Spain), and Zurich (Switzerland) over a six-year period from 2013 to 2018. While micro-level innovation practices can induce sustainability shifts, particularly when aligned with policy interests, the study also observed potentially negative impacts due to a lack of alignment at the initiative or city-region levels.

Camila Garcia Fernandes de Souza Margem, Néliton Marques da Sílva · Cadernos Metrópole · Brazil (Manaus)

This article analyzed the feasibility of implementing urban agriculture (UA) on idle land within the Tarumã – Ponta Negra Environmental Protection Area in Manaus, Brazil, as a tool for territorial governance and urban planning. Semi-structured interviews and card sorting techniques were applied to the target population. The study found that the use of idle land for UA is not envisioned as a territorial governance instrument, a situation exacerbated by municipal authorities hindering the legitimization of bills for such land use.

Helda Morales, Bruce G. Ferguson, Kimberly Chung, Ronald Nigh · Desenvolvimento e Meio Ambiente · Mexico (Chiapas)

This study explored the potential and limitations for agroecological scaling through formal educational structures, using the LabVida school gardens program in Chiapas, Mexico as a case study. Through training, educators gained an appreciation of agroecology and applied practices in their school gardens, although their understanding of agroecological principles and scientific process remained limited. The program's greatest impact was on educators’ eating habits and their perception of the value of local knowledge and its relevance to schoolwork.

Olga Domené-Painenao, Francisco Herrera · Desenvolvimento e Meio Ambiente · Venezuela

In Venezuela, the Bolivarian Revolution since 1999 has seen the unfolding of harsh class and food system contradictions. While the Program Degree in Agroecology (PDA) at the Bolivarian University of Venezuela has trained over a thousand graduates who contribute to agroecological scaling and urban agriculture, the abstract highlights the persistent "harsh class and food system contradictions" within the country. This indicates ongoing equity challenges despite agroecological efforts.

Manuela Maluf Santos, Paulo Eduardo Moruzzi Marques · Estudos Avançados · Brazil (São Paulo)

This article conceptually explores the "locavorism" food activism movement, noting that its practical application can have diverse and even antagonistic effects. To analyze these contradictions, two farmer organizations in São Paulo involved in local consumption circuits were interviewed to understand the potential social and environmental effects of this purchasing model. The abstract does not present the findings of these interviews.

Paul D. Jensen, Caroline Orfila · Food Security · United Kingdom

This case study used publicly available data to spatially analyze the urban food system of Leeds, UK, assessing its food security and resilience. The study found that while Leeds has a significant food production and provision system, it is not food secure in terms of providing sufficient energy or macronutrients, nor does it function equitably for all residents. Improving the system, including through urban farming, would require high investment, multi-sector cooperation, and strong governance.

Nur Surayya Mohd Saudi, Mohd Nor Yahaya, Muzafar Shah Habibullah, Baharom Abdul Hamid, Muhammad Amirul Azlan, Mohd Haizam Mohd Saudi · Turkish Online Journal of Qualitative Inquiry · Malaysia

A study on Malaysia's Movement Control Order (MCO) noted the extension may effectively contain the pandemic's spread but is expected to have a devastating impact on food security, and proposed urban farming as a means of generating household income and food security for the low-income B40 group. Econometric modeling of the effect of lockdown measures and COVID-19 on selected vegetable prices found that not all vegetables reacted uniformly to lockdown measures; price increases were associated with reduced household purchases and income, denying people access to food security. While the substitutability of vegetables allowed some switching to cheaper options, the study states that higher food prices themselves deny people access to food security.

Elia Apostolopoulou · · Europe (Greece)

Focusing on the two largest Greek cities, Athens and Thessaloniki, this study examines why urban community gardening surged after the 2008 financial crash, drawing on urban political ecology, radical social and urban geography, and qualitative social research. Greece is treated as a distinctive case: it saw this post-2008 increase in community gardening without having a prior long history of the practice, unlike parts of the Global South. The author concludes that the creation of community gardens is tied to rising inequality in European cities in the aftermath of the 2008 crisis, functioning both as an act of disobedience against the grabbing of public land and as a demand for reclaiming the urban commons.

Samuel Ziem Bonye, Gordon Yenglier Yiridomoh, Emmanuel Kanchebe Derbile · International Journal of Urban Sustainable Development · Africa

A mixed-methods study in Wa Municipality, Ghana, examined how peri-urban agricultural land use change affected farmers' food security, surveying 235 smallholder farmers with questionnaires, interviews and GIS-based historical data. Over the past three decades, peri-urban agricultural land was drastically lost to residential and infrastructural development, and this land use change resulted in food insecurity, with most smallholder farmers unable to meet their food needs over the past decade.

James J. Connolly · · United States (California)

This case study examines the leading edge of gentrification along San Francisco's Third Street T streetcar line. Bayview-Hunters Point (B.V.H.P.), the end of the streetcar line's first phase, is an ethnically mixed, working-class neighborhood and the last historic concentration of African American residents in San Francisco. While gentrification-driven change is already visible further up the line, its presence in B.V.H.P. remains comparatively shallow so far. Nonetheless, many residents and community activists perceive that a fast-moving gentrification frontier leaves them with a conundrum: remain in a contaminated, post-industrial, climate-exposed environment, or advocate for their health while risking displacement. The neighborhood has seen greening such as community gardens and a waterfront promenade, alongside inequalities including enduring racial segregation, environmental privilege, green gentrification, luxury development, climate-related health risks, and continued exposure to contamination.

A land-cover change study (Journal of Environmental Planning and Management, 2021) applied a supervised classification of Landsat satellite imagery from 1986, 1996, 2005, and 2015 to Argentina's largest peri-urban horticultural region in South America. Between 1986 and 2015, open-field horticulture extent decreased by 51.47%, while greenhouse area increased by 2652.83%, high-density urbanization expanded by 111.58%, and low-density urbanization increased only between 1986 and 2005—expansion that came at the expense of natural grassland, herbaceous parks, and livestock land. The authors conclude this reflects a regional process of urban growth and productive intensification that has caused losses of open-field horticultural areas and produced a non-equitable distribution of remaining semi-natural areas, and they call for territorial planning that prioritizes ecologically resilient, semi-natural land cover.

Panagiota Kotsila, Isabelle Anguelovski, Francesc Baró, Johannes Langemeyer, Filka Sekulova, James J. Connolly · Environment and Planning E Nature and Space · Spain (Barcelona)

This paper analyzes nature-based solutions (NBS) as discursive tools that create an inviting space for nature's neoliberalization processes, examining two city-initiated projects in Barcelona, Spain: the Passeig de Sant Joan green corridor and the Espai Germanetes community garden. The study found that urban nature can serve elite economic players at the expense of widespread socio-ecological benefits. It also noted that outcomes regarding neoliberalism and its contestation were very distinct between the two projects due to different forms of governance.

Julia Davies, Corrie Hannah, Zack Guido, Andrew Zimmer, Laura E. McCann, Jane Battersby, Tom Evans · Food Policy · Sub-Saharan Africa

This study investigated the association between urban agriculture (UA) and household food security in smaller African cities and towns, using survey data from 2,687 low- and low-middle income households in 18 urban areas with populations of less than 200,000 across Zambia and Kenya. The analysis found that 33% of households in the sample engaged in UA, but there was limited statistical significance in the relationship between UA and household food security. Key barriers identified were settlement formality, property rights, and distance from food retailers.

The Nærum Allotment Gardens in Denmark are publicly owned and privately leased and managed. A national Allotment Garden Association provides gardeners with a forum to counter the inherent vulnerability of these allotments to land use change. This structure indicates a persistent vulnerability of the gardens to changes in land use.

Larissa Maas, Rosane Malvestiti, Leila Amaral Gontijo · Cadernos de Saúde Pública · Brazil

This study assessed the main difficulties faced by seven urban organic farmers in two Brazilian cities without policies encouraging urban farming, through semi-structured interviews conducted from July to December 2018. The research revealed challenges such as a lack of trained labor, inadequate machinery and equipment for small areas, and insufficient financing, indicating that the absence of policies hinders the development of urban organic farming.

Paule Olivia Akotto, Dorothée Boccanfuso, Marie-Ève Yergeau · Cahiers de recherche · Global

This exploratory review synthesizes 35 reports and articles published between 1980 and 2019 to assess the potential of urban and peri-urban agriculture (UPA) to build resilience against poverty, food insecurity, and environmental challenges in developing countries. The review found that UPA creates one job for every 50 to 100 individuals, but these jobs are generally seasonal, and market access remains a significant constraint for farmers.

Jonathan London, Bethany B. Cutts, Kirsten Schwarz, Li Schmidt, Mary L. Cadenasso · Agriculture and Human Values · United States (California)

This study, based on 24 interviews with urban agriculture (UA) leaders in Sacramento, California, identifies three "taproots" of UA projects: justice, health, and market. The analysis reveals how these roots interact differently with racial capitalism, creating disparities in their growth trajectories. Specifically, UA projects associated with the justice taproot are historically underrepresented and undervalued.

Azizan Marzuki, Ahmad Sahir Jais · PLANNING MALAYSIA · Malaysia

This qualitative exploratory review, based on a Systematic Literature Review of secondary data, investigated the connection between urban sprawl and its impact on agricultural productivity and food security in Malaysia. The study found that urbanization did affect Malaysia's food security self-sufficiency level, particularly for land-intensive food products like vegetables and livestock, due to the conversion of agricultural lands.
