Case studies in Provence and Tuscany indicate that planning prescriptions and land-market control are insufficient for protecting farmland on the urban fringe. Farmland is not effectively protected if regulatory approaches are not integrated into a global strategy for agriculture and food based on community involvement. Farmland protection policies are more effective when combining top-down policies with bottom-up initiatives and recognizing the multifunctional character of urban agriculture.

This research explored how low-income urban agricultural (UA) projects in North America and Europe can be strategically supported for sustainability. The authors analyzed UA projects using the 5 Level Framework and the Framework for Strategic Sustainable Development, along with Leverage Points, to understand their current reality. The study produced strategic recommendations and guidance for UA projects to foster a societal shift towards sustainability.

Paul. A. de Graaf · · Netherlands (Rotterdam)

This research offers a top-down perspective on Rotterdam's urban landscape to identify spatial opportunities for urban agriculture. It defines promising urban agriculture types based on international best practices and local expert judgment, then formulates criteria for opportunities based on spatial, environmental, and social demands and benefits. The study aims to support bottom-up urban agriculture projects by mapping these opportunities and demonstrating their potential through design case studies, linking them to urban sustainability and resilience.

Johannes Novy · · Germany (Berlin)

This seminar aims to identify the contemporary winners and losers in Berlin's urban development and how this is manifested and reproduced through urban space. Central points of interest include conflicts surrounding the "New Berlin," the potential and threats of Berlin as a "Creative City," the spatial dimension of social exclusion, the integration of migrants, and perspectives of the "right-to-the-city-movement" (e.g., guerrilla gardening). Berlin's urban landscape will be compared to those of Paris and St. Petersburg.

Barbara Uhlig · edoc Publication server (Humboldt University of Berlin) · Germany

This study analyzes guerrilla gardening as a protest movement where activists plant flowers, trees, and vegetables on derelict urban spaces without owner permission. The motivations for guerrilla gardening are pragmatic, ecological, political, and aesthetic, though its artistic status is often denied. The study demonstrates that guerrilla gardening aligns with George Dickie's institutional theory of art and can be classified as art.

A long-term study in southeastern France examined the development of Community Supported Agriculture (CSA) as an alternative marketing system for fruits and vegetables. The study found that the non-market dimension of CSA appears to have disappeared over time, from its initial form to current basket systems. This change is attributed to the diversification of farmers' sociological profiles and the transformation of marketing conditions for organic local products.

Soil samples were collected from the former "Piast" cement plant within Opole city borders, Poland, and nearby allotment gardens to study radioisotope activity concentrations. Naturally occurring radioisotopes and artificial Cs were found, with K and Cs showing the biggest radioactivity concentration. No significant differences in radionuclide activities were found between soil samples from the former industrial estate and the allotment gardens.

The "Small steps of Agenda 21" project in the "J. Mirò" nursery school in Padua, Italy, engaged children in participatory planning for their school garden. Children actively improved the garden, fostering awareness of community discussion and participation. The project demonstrated that children improved their sense of inclusiveness and responsibility.

Cécilia Claeys, Jean-Noël Consalès, Carole Barthélémy · · France (Marseille)

This paper re-examines the question of nature in the city through emerging environmental paradigms, using Marseille, a French Mediterranean city, as a case study. An interdisciplinary analysis combining sociology and geography revealed that new modes of urban and suburban nature management (e.g., National Park, greenways, community gardens) question spatial boundaries between wild and artificial. However, the uses of these spaces are still marked by persistent social segmentations.

Neil Ravenscroft, Niamh Moore, Ed Welch, Andrew Church · University of Brighton Repository (University of Brighton) · United Kingdom

This paper explores the theoretical foundations of Community Supported Agriculture (CSA) in the UK, a cooperative venture where communities share farming risks and harvests. It suggests that CSA's theoretical underpinnings are gift-based, fostering deep connections among people, farmers, and the environment. The paper argues that CSA's significance lies in its rejection of market-based food communities and its demonstration of durable community forms for making multiple connections.

This study, conducted in Trabzon, Turkey, from February to June 2007-2008, aimed to reveal changes in agricultural knowledge among twenty-four 6th-grade students participating in a "School Garden Project." Using the RAST Model, students were divided into 6 groups, and data was collected through pre- and post-application interviews and researcher observations. The project generally achieved desired alterations across all five agricultural course targets.

Sarah Bell, Cristina Cerulli · UCL Discovery (University College London) · United Kingdom (London)

A case study of a newly established community garden in London was analyzed. The study used the multi-level perspective on transitions to sustainable development by Grin et al. (2010) and modeling of cities as complex systems by Wilson (2010a) and Batty (2005) to analyze the potential for emerging community gardens to contribute to transitions to sustainable urban food systems. Urban agriculture is considered a core element for the future of sustainable cities.

This chapter explores the social organization of voluntary urban food production in Britain, identifying two dominant modes: collective activities and individual allotment gardens. It notes that the organization of unpaid labor is an under-researched aspect and a key restraint on urban agriculture's expansion. The study found that relations between these two modes can be antagonistic, particularly when land is scarce.

This study investigated the presence of zoonotic agents in small ruminants kept on city farms in southern Germany, sampling feces and nasal liquid from 48 animals (28 goats, 20 sheep) across 7 city farms and one activity playground. Findings revealed that 100% of sampled sheep and 89.3% of goats carried Shiga toxin-producing Escherichia coli (STEC). Staphylococcus spp. were detected in 75% of both sheep and goats, and Campylobacter spp. in 25% of sheep and 14.3% of goats. Neither Salmonella spp. nor Coxiella burnetii was found.

FALLETTI, MADDALENA · TERRITORIO · Italy

This 2012 introductory piece for the Italian journal TERRITORIO reorganizes contributions on urban agriculture by subject matter to surface several contradictory aspects of the ongoing debate. It offers three interpretive keys: the first reproduces the debate within its own sealed compartments while attempting comparison through juxtaposition of contrasting attitudes; the second highlights a transverse conceptual dichotomy with strong implications for planning — urban agriculture as a remedy for city problems versus the urban countryside as a new form of urban plan; the third examines the debate in the specific context of Milan.

Ross Wilson · Journal of Urban History · United Kingdom

A historical study using archive material and newspaper reports examines the development of allotment gardens in the northern English city of York in the early twentieth century. Applying Giddens's structuration theory, it investigates how relationships between citizens and the York City Corporation developed, and reexamines allotment gardens as a lens for understanding wider urban life in Britain. It argues that although allotment gardens have featured only partially in studies of civic reform, identity and governmentality, their centrality to working-class life in Britain warrants greater scholarly attention.

José Luis Fernández de Casadevante, Nerea Morán Alonso · Hábitat y Sociedad · Spain

This article examines community allotment gardens as an emerging phenomenon in Spanish cities, focusing on Madrid. It describes how allotments have arisen through the efforts of neighbourhood associations, social groups, and ecologists, in a dynamic that has proliferated over the preceding six years, building a critical discourse around urban sustainability and forming coordinated structures able to introduce the topic into the public sphere and the political agenda. These allotments are spaces articulating experiences of reflection and participative intervention around the city, public space, group identities, and procedures of spatial appropriation. The initiatives are also described as approaching the notion of food sovereignty as a strategic issue for the future of cities.

David Pearson, Chris Firth · Biological Agriculture & Horticulture · United Kingdom

A profiling study of community gardens in one region of the United Kingdom, which found that gardens differ in how and when they were established, how they are managed and funded, their size, and who uses them and for what purposes. The two most common objectives cited by organizers were community development through food-related activities and contributing to environmental sustainability. On longevity, one third of the community gardens in the study region were found to be no longer active, indicating that survival is not assured. To improve durability, the study suggests gardens need to build a sense of ownership within the local community and be managed in ways consistent with their funding source's conditions and volunteers' expectations.

This doctoral dissertation proposes urban-system strategies for reducing energy consumption and greenhouse gas emissions by introducing eco-innovation into buildings across two economically, socially, and climatically different contexts: Mexico and Spain. For Mexican social housing, it examines an eco-retrofit strategy combining efficient eco-technologies, shading and insulation (roof shading, wall overhangs, window and roof louvers, green roofs), and food production (tomatoes), calculating cooling energy demand and the cumulative energy and CO2 emissions associated with shading materials. For Spain, it examines barriers and opportunities for installing intensive food-producing greenhouses on rooftops of buildings in Mediterranean European cities through multidisciplinary expert seminars, and analyzes potential heat-flow synergy between a building and a rooftop greenhouse focused on winter heating energy demand for a service building in Barcelona. Results indicate that eco-technologies can reduce annual energy consumption in social housing by 31% (35.7 kWh/m2/year), roof-shading strategies save 126 kWh/m2/year, and tomato production in social housing in Mérida, Mexico could contribute a reduction of 662 gCO2eq per kg of tomatoes produced.

Chiara Tornaghi · TERRITORIO · United Kingdom

This paper presents an English case of urban agriculture, the Edible Public Space Project in Leeds, situated within urban agriculture initiatives committed to socio-environmental justice, the reproduction of common goods, and urban planning that promotes the right to food and bottom-up construction of urban space. The case study is framed as action-research at the intersection of urban planning policy, community work, and critical geography. Unlike many similar initiatives, the project is presented not as a merely temporary activity tucked into the city's spare folds, but as an experiment that imagines and implements alternatives to current forms of urban planning, contextualized in light of the ecological, financial, and social crisis of the preceding decade.

Arturo Sergio Lanzani · TERRITORIO · Italy

This study treats Brianza, Italy, as a prototype of recurring relationships between residential and agricultural spaces in contemporary towns and cities, using their differences to trace the evolution of the historical landscape, the causes of its deterioration, and new planning possibilities. The simplified rural fabric of the Vimercate countryside, the strings of woodland and built-up areas in the hills, urban clearings, and the woodland and countryside of Groane are each said to open prospects for new, locally specific types of urban agriculture. The proposed future is plural, examining different relationships among agriculture, collective spaces and redevelopment of existing settlements, while opting for a halt to urban growth and reconstruction of infrastructure and landscape quality in the Brianza area.

Les Levidow, Katerina Psarikidou · · United Kingdom

In Manchester, England, environmental and health issues have been folded into a wider agro-food strategy aimed at making the city "more sustainable." With support from state bodies and charities, several initiatives have expanded access to fresh, healthy food, particularly in "food deserts," mobilizing resources, skills, and voluntary labor through "community engagement" to create "community spaces" for social inclusion. Manchester's agro-food networks shorten supply chains by linking peri-urban agriculture more directly with urban consumers and by promoting urban agriculture grounded in local resource mobilization and personal trust, offering an alternative to conventional agro-food chains; food relocalisation is described as helping overcome socio-economic inequalities and health problems, with Manchester initiatives cooperating to build environmentally sustainable, socially just, healthy communities and reconstructing local identities and social commitments, within a national policy context that advocates food relocalisation but provides little actual support. Despite that activity, the larger food system in Manchester remains dominated by conventional agro-food chains, and community food initiatives play only a marginal role, leading practitioners to discuss how to overcome these limitations; from 2010 onward, the UK government's austerity regime is described as undermining state support further, making community engagement even more important for mobilizing resources.
