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.

Density changes of red foxes and martens were investigated in the urban area of Warsaw from 2015-2021 using winter snow tracking. Results were compared with data from 1976-1978 and 2005-2008, showing a gradual increase in the average density of both mesocarnivores across all habitat types since the 1970s. A decrease in density for both species was observed in the 2017/2018 winter season, with the reasons for this decline remaining unclear.

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.

Paweł Matacz, L. Świątek · Sustainability · Poland (Szczecin)

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.

Sandra Schwindenhammer, Denise Gonglach · Politics and Governance · Germany

This qualitative and participatory case study in Germany examined the governance implications of an emerging technology in urban agriculture that connects wastewater treatment and agricultural production for urban hydroponics. The analysis found that while this technology has the potential to facilitate SDG implementation, it simultaneously creates new sector interlinkages between water and food, leading to policy demands that necessitate more integrated policymaking.

Mariana Schmitz Gonçalves, Aguinaldo dos Santos · e-Revista LOGO · Netherlands (Rotterdam), Switzerland (Geneva)

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.

Arthur Feinberg, Elena Hooijschuur, Nicole Rogge, Amineh Ghorbani, Paulien Herder · Journal of Artificial Societies and Social Simulation · Europe

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.

Sabina Rossini Oliva, Rafael López Núñez · Agronomy · Spain

This study investigated potential toxic element contamination in food and soils from urban and rural gardens in Seville, Spain, including urban gardens in a mining area. Soils from mining gardens were the most contaminated. While arsenic, cadmium, and lead concentrations in studied vegetables did not exceed legal maximum levels, high levels of barium (up to 42 mg kg−1) and zinc (up to 123 mg kg−1) were found in leafy green vegetables like chard and lettuce, indicating a need for further study on associated human health risks.

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.

Green infrastructure refers to an interconnected network of natural or semi-natural areas whose proper functioning generates benefits for human societies and strengthens their resilience. It can simultaneously produce multiple benefits such as improved stormwater management, creation of cool islands and species habitats, job creation in urban agriculture, economic valuation of real estate, and new nature experiences. Green infrastructure allows for the reinvention of urban landscapes and a reconsideration of our intimate relationship with living things.

Gurpinder Singh Lalli · · United Kingdom

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.

Michelle Brener Mizrahi · European Journal of Cultural Management and Policy · Europe

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.

Peter Gittins, Leigh Morland · The International Journal of Entrepreneurship and Innovation · United Kingdom

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.

Martina Artmann, Katharina Sartison · RWTH Publications (RWTH Aachen) · Germany

This study investigated the implementation and impact potential of edible cities in three German case studies (Andernach, Haar, Munich) as part of a project funded by the German Research Foundation (DFG). Edible cities are a concept that utilizes public spaces to provide free food and urban gardening opportunities for citizens.

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.

Roberto Leggero, Mirella Montanari · University of Vienna · Italy

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.

Ambrogio Zanzi, Federico Andreotti, Valentina Vaglia, Sumer Alali, Francesca Orlando, Stefano Bocchi · Sustainability · Italy (Milan)

This study aimed to assess the benefits of an agroecological requalification of a dismissed peri-urban area in the South Milan Agricultural Regional Park, Italy. Using I-Tree Eco software, the provision of ecosystem services from planting new hedgerows was simulated over 30 years, showing that the planted area becomes an essential supplier of regulating ecosystem services for neighborhoods, increasing carbon storage and air pollution removal. A notable increase in carbon sequestration was observed at the end of the simulation, demonstrating a replicable methodology and techniques for assessing ecosystem services in urban and peri-urban environments.

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.
