This paper critically examines urban experimentation for sustainability, arguing that urban experiments are often assessed from a diffusion-oriented perspective that over-emphasizes unifying visions and neglects unsuccessful initiatives. Using a novel methodological approach combining a metropolitan geodemographic typology with qualitative data on 166 active and inactive urban agriculture initiatives across London, the paper demonstrates that neglecting the diversity of urban socio-economic, demographic, and physical contexts may lead to the erroneous suggestion that only demographically privileged places can achieve sustainability. It highlights that contextual differences at neighborhood levels significantly influence socio-spatial patterns of experimentation.

This chapter proposes understanding urban agriculture, specifically shared gardens in Gennevilliers, as part of a collective project to develop a more environmentally respectful, food-producing city. It also views urban agriculture as a potential lever for women's emancipation. The study will explore how urban agriculture can foster collective responsibility and become a concrete vector for changing relationships within the Gennevilliers context.

An archaeological evaluation was conducted for the Kalewater Community Council at Morebattle Recreation Ground, Scottish Borders, from May 24-28, 2021. This work was related to land purchased to provide community facilities, including a community garden. Five trenches, totaling 166.5 sq.m, were excavated, targeting anomalies from a September 2019 geophysics survey, but very shallow linear ditches and a possible wall/drain were found that did not appear to relate to the geophysics anomalies.

This chapter explores the historical trajectory of large urban parks and the broad pattern of urban green space from the pre-modern period to the present day in European cities. It notes that urban green spaces, including large urban parks, have faced significant financial, development, and management challenges in recent decades. However, these parks have also benefited from inter-city competition, as large green areas are crucial for a city's international identity and attractiveness.

This study focuses on a landscape design project for the Historical Yedikule Gardens in Istanbul, an urban agriculture area with 1500 years of history. The project aimed to reorganize the farmland to enhance its contribution to the urban green space system, provide economic gain and hobby areas for citizens, and preserve its cultural past. Conducted under historical environmental protection and urban agriculture area regulation principles, the renewed area, with its historical, cultural, and economic values, is shown to contribute to both users and the city.

This report selects relevant soil quality indicators for assessing soil quality in the Amsterdam metropolitan region, specifically for 'urban agriculture' and 'urban green' applications. It notes that while agricultural soil quality indicators exist, specific ones for urban environments were lacking. A case study in Amsterdam's 'Fruittuinen van West' area develops an example for using these indicators in urban agriculture.

This study surveyed 111 community gardeners in Berlin and Munich, Germany, to understand the socio-psychological factors predicting pro-pollinator behavior. Using generalized linear models, the analysis revealed that gardeners who were fascinated by pollinators, held positive attitudes, and felt joy about seeing them reported intentions to protect or support pollinators. This suggests that fascination and joy can be harnessed for pollinator research and conservation efforts.

This article addresses the problematic heritage of Nazi German underground air raid shelters in Szczecin, Poland, by exploring their revitalization for urban agriculture. Through inventory and analysis, a modular hydroponic plant-growing system adapted to these prefabricated spaces was proposed. This solution aims to overcome negative associations, strengthen food sovereignty, initiate bottom-up community activity, and build social ties in residential neighborhoods.

This paper analyzes Thomas Kling’s poem „geschrebertes idyll, für mike feser“ as an "allotment garden idyll" within 'new nature poetry'. While Kling skillfully engages with the idyll genre and offers ecological, social, medial, and historical critique, the study finds that he presents a decidedly patriarchal self-image, which contemporary readers would likely find less acceptable.

This study aimed to identify the impact of visit frequency to community gardens in Slovakia on members' perception of membership importance, satisfaction with community relations, perceived improvement in social relations, and influence on quality of life. A mixed-methods approach, including a questionnaire survey and semi-structured interviews, was used. The analysis did not confirm a dependence between visit frequency and the gardens' impact on members' communities, and found no statistical relationships between the variables in the analyzed data set. However, members positively rated relationships within those communities.

This study aims to identify heuristics that allow for expanding social cohesion in urban agriculture initiatives. Two ex-post-facto case studies were conducted in Rotterdam, Netherlands, and Geneva, Switzerland. Another objective of the research is to reflect on the use of these heuristics in Service Design and Design for Social Innovation. The research's contribution lies in proposing meta-actions for converting the ten identified heuristics into Design actions.

This paper examines Milan's Porta Nuova re-urbanization project (2004-2015), which features Vertical Forest skyscrapers as symbols of urban greening. Activists and resident groups strongly opposed the project, criticizing the privatization of a public park and high rents, arguing it represents a top-down privatization leading to exclusion and gentrification. In response, these groups developed a public community garden in the same neighborhood as an alternative model for democratic horizontal urban greening.

Fabio Amato, Lucia Simonetti · Journal of urban regeneration and renewal · Italy (Naples)

This paper focuses on the social urban garden in the Ponticelli neighborhood on the eastern outskirts of Naples, Italy, an area facing significant social and cultural problems including high unemployment and crime rates. The urban garden demonstrates how social cohesion can be built through urban agriculture and contribute to sustainability. However, the initiative risks remaining isolated and providing limited benefit to regional environmental sustainability efforts if not framed within an overall metropolitan strategy.

This paper presents an agent-based model to explore conditions for sustained participation in urban community gardening projects in Europe, validated with data from Germany and the Netherlands. The study found that not all of Ostrom's Design Principles for collective action lead to higher participation; instead, participation depends on specific combinations of these principles. It also highlights that sanctioning mechanisms are not always beneficial and can be counter-productive in certain contexts for volunteer participation.

Heavy metal (HM) and metalloid concentrations were assessed in 200 urban horticultural soils across ten UK cities. HM were found to be widespread, with most concentrations below UK soil screening values (C4SLs). However, 83% of lead (Pb) concentrations exceeded C4SLs, which is a significant concern. Bioavailable HM concentrations represented a small fraction (0.01–1.8%) of total concentrations, and black carbon (BC) and organic carbon (OC) were suggested to contribute to HM immobilization.

This chapter reflects on food education and school gardening programs in England, drawing on ethnographic techniques employed since 2012. It discusses the food curriculum and the impact of engaging with school gardens, which are termed 'school farms' in this context. The work highlights how these spaces, including curriculum and school grounds, play a key role in shaping future thinking for children and young people and support their wellbeing.

This paper analyzes how Incredible Edible Todmorden (IET), a community-led project, operated notions of sustainability through permaculture and urban farming to focus on community building and its impacts on education and local culture. The paper puts forth the argument that the discursive operationalization of sustainability can produce important effects in community building, education, and local culture at a local level.

This case study explored the business model and growth challenges of 'Growing Better', a micro-social enterprise urban farming facility in the Leeds City Region, UK, which provides a supportive working environment for people with mental health issues. Findings suggested that the potential for growth lies with the social entrepreneur's ability to harness external stakeholder support. However, any venture development should also inform the effective utilization of resources through operations management.

This research investigated the distribution, bioavailability, and total forms of zinc (Zn) in soils from domestic and family allotment gardens across six cities in south-eastern Poland. It found that horticultural treatments had a greater impact on sandy soils, and higher Zn contents were present in humus horizons. High values of concentration and Igeo indices indicated significant Zn pollution in these soils, with bioavailable zinc forms being notably high.

This investigation compared urban agriculture in the proto-city of Chieri and Novara in medieval Piedmont, Italy, finding that urban agriculture was influenced by the city's network and environmental relationship. Chieri's arid clay soils and water scarcity led to specialized wine production and in-city processing areas. Novara's Roman urban model and surrounding countryside facilitated vegetable gardens and peri-urban crops, demonstrating how different urban structures and territories generated diverse forms of urban agriculture.

The "Green Symphony" project in Lanuvio, a municipality near Rome, Italy, transformed a vacant ARES site into a smart and sustainable urban farm. The project integrated aquaponic systems, permaculture, vertical farming, and energy harvesting technologies. The developed farm is projected to generate 7 tons of vegetables, fruits, herbs, and fish annually, create 3 stable jobs, and recoup investment costs within a maximum of 5 years.

A comparative study analyzed the use and development of allotment gardens (AGs) in Westphalia and Lippe (Germany) and Wielkopolska (Poland). AGs in Westphalia and Lippe are accessible and harmoniously integrated into the landscape, while AGs in Wielkopolska are less accessible, prioritize internal users, and do not always blend with their surroundings. The considerable freedom enjoyed by Polish plot-holders leads to a gradual marginalization of edible-plant growing.

In June 2012, an experimental urban vegetable garden was established on the rooftops of AgroParisTech in Paris, France, marking the integration of urban agriculture into cities. This initiative coincided with the "Gardens in the City" exhibition, organized by the Museum of the Living and the League of Education. Since then, other urban agriculture projects have emerged, particularly in the capital.

To investigate drivers of transformation in alternative food networks (AFNs) in Germany, interviews were conducted with producers and consumers in three AFN models: Community Supported Agriculture (CSA), food co-operatives, and self-harvest gardens, followed by qualitative content analysis. Participants in CSA and food co-ops reported a strong reconnection between producers and consumers, indicating transformative potential, while self-harvest gardeners primarily sought individual capacity building and access to their own garden. AFN participation was suggested to foster incremental transformation towards more sustainable food practices and a respective value system.
