This chapter presents three case studies on collective action in Italy. The "Land Conservation" project in Tuscany involves a local public body and farmers co-producing environmental services to enhance flood resilience and landscape maintenance. The shared garden in Campania describes the concerted management of a green area on a degraded site transformed into an eco-archaeological park. The collective management of mountain meadows and pastures in the Aosta Valley coordinates multiple stakeholders with regional support to maintain the landscape and preserve biodiversity.

Pierluigi Musarò, Roberta Bartoletti · Archivio istituzionale della ricerca (Alma Mater Studiorum Università di Bologna) · United States (New York City), Italy, Europe

This study maps urban gardening in New York City and Italy, tracing the evolution of urban gardens from 19th-century worker gardens to the 1970s community garden movement. It notes that contemporary urban horticulture in Italy, while influenced by the US movement, primarily focuses on social, cultural, and civic-political values, with economic and productive potential not being central or sometimes excluded.

Meliz Akyol, Hayriye Eşbah Tunçay · · Turkey (Istanbul)

This study explores the role of productive landscapes, specifically urban agriculture, in creating resilient cities. Istanbul, Turkey, is presented as a case study, noting the historical influence of food on the city's image and traces of agricultural uses along the Theodosian Walls and in old neighborhoods. Despite agricultural lands being transformed into settlement areas due to rapid urbanization, the study suggests that combining agriculture with new technology, architectural trends, and sustainable master plans will encourage urban agriculture and create more resilient urban environments.

This chapter presents three Italian case studies: "Custody of the Territory" in Tuscany, a community garden in Campania, and mountain pastures in Aosta Valley. These cases discuss agri-environmental public goods provided by collective action, factors affecting outcomes in collective action, and policy measures supporting collective action, through environmental services by local government agencies and farmers' agreements, collaborative green spaces converted from degraded sites, and collective management of mountain pastures with regional support.

Schram-Bijkerk He, Dirven-van Breemen Em, Otte Pf · Rivm (National Institute for Public Health and the Environment) · Europe

This report identifies self-reported local and shared success factors for introducing green space and urban agriculture in several European cities to mitigate climate change effects. Key factors include national legislation promoting nature conservation, strong cooperation between local authorities and the public, and incorporating minimum green space requirements into zoning plans and housing projects. Urban agriculture has been adopted as part of green policy in cities like Manchester, Lyon, and Paris to ensure a supply of healthy food.

Michael Koch, Martin Köhler · · Germany (Hamburg)

This paper discusses how new types of open spaces, beyond officially designated ones, are gaining focus in urban planning discussions in Hamburg, Germany, particularly concerning urban densification and new partnerships for maintaining urban open spaces. These spaces, including traffic junctions, railway embankments, industrial fallow land, and private gardens, serve as venues for trends like urban gardening and urban explorations. The study, presented in four volumes for Hamburg, explores the actual and potential contributions of these spaces to the open space provision for the entire urban population, not just in inner-city areas or by young urban milieus.

Paula Nahmías, Yvon Le · Environnement urbain · France

This paper attempts to define "urban agriculture" given the diversity of its forms and representations. Based on field observations in Brittany, France, it concludes that beyond its proximity to the city, the urban character of agriculture is defined by its functionalities and its integration into the agglomeration project.

Veguita de Graná · · Spain (Granada)

Rosa Felix explored urban gardens in metropolitan Granada, Spain, in 2013, linking them to employment opportunities. She noted that such experiences have a long history in many countries. Felix concluded that urban gardens would be successful if public administrations supported their creation.

Elisa Marraccini, Sylvie Lardon · HAL (Le Centre pour la Communication Scientifique Directe) · Italy (Pisa)

The first Spring School on "Agricultural management in periurban areas," held in Pisa from May 20-27, 2013, aimed to introduce participants to key concepts and methods in Landscape and Territory Agronomy for analyzing and supporting land planning in peri-urban agriculture. This case study took place in the urban region of Pisa, Central Italy, where main spatial issues were identified and action proposals discussed.

Isabelle Anguelovski · City and Community · Spain (Barcelona), United States (Boston), Cuba

The role of place attachment in environmental mobilization among local activists improving degraded spaces, such as urban farms and community gardens, was investigated in three marginalized neighborhoods in Barcelona, Spain; Boston, USA; and Havana, Cuba. Activists in all three locations used environmental projects to express grief over community loss, fear of erasure, and emotional connection to their neighborhoods. They aimed to construct "safe havens" and remake places for residents to address environmental trauma.

Isabel de Felipe Boente, Teresa Briz · · Spain

This paper describes the impact of urban agriculture (UA) in political, socioeconomic, and environmental scenarios, and analyzes its situation in Spain, where it is mainly located on roofs, walls, indoors, and ground places. It discusses local regulations, barriers, and opportunities for UA, as well as the role of stakeholders and neighbor communities. The paper suggests actions to improve UA, including urban planning and education.

Marco Luca Stanchieri · X Jornadas de Sociología · Spain (Barcelona)

This paper explores the concept of "urban voids" in contemporary cities, focusing on abandoned plots resulting from unfulfilled urban reform projects. It argues that despite being defined as "voids," these spaces are sites of active human social practices, serving for common appropriation, self-management, conflict, and negotiation, fostering neighborhood cohesion and community action. Based on ethnographic data from Barcelona, the paper aims to expose the misleading nature of urbanistic language that defines socially vibrant spaces as "voids," questioning the social exclusion mechanisms supported by such definitions.

Tim Cook · · United Kingdom (Yorkshire)

The gardening charity RHS Yorkshire in Bloom launched a £100,000 fund to offer more support for community gardeners. For the first time, people across Yorkshire and the Humber can apply for these funds.

Giovanni Attili · IRIS Research product catalog (Sapienza University of Rome) · Italy (Rome)

This study focused on community gardens in Rome, Italy, which largely result from informal appropriation practices. While these gardens can enhance environmental and social quality of life, they require institutional support and present a crucial challenge for urban planning. The study highlights the need to explore tensions between social practices and institutional powers, and questions how public policy can legitimize these self-guiding societal expressions.

Daniele La Rosa, Francesco Martinico, Riccardo Privitera · TERRITORIO · Italy

This study discusses how non-urbanized areas in metropolitan contexts can be reconsidered for new land uses, combining peripheral urban agricultural production with environmental protection for climate change adaptation and ecosystem service production. Through a review of urban planning instruments in Mascalucia, a new land-use scenario for non-urbanized areas was proposed using a land suitability model that combined land cover and fragmentation analysis.

Raúl Puente Asuero · Revista de estudios regionales · Spain

Based on 30 interviews conducted between May and November 2011 with farmers, farming associations, irrigation associations, the University of Granada, business associations, local councils, political parties and citizen platforms such as Salvemos la Vega, this study examined La Vega de Granada, the agrarian landscape along the River Genil in central Granada province, Spain. It shows that this once-unified agrarian landscape has, in recent decades, become a fragmented and discontinuous aggregation, and reports that in the absence of administrative coordination, social movements have taken the lead in protecting and revalorizing its agrarian heritage.

Michael Koch, Martin Köhler · · Germany

Against the backdrop of debates on densifying German cities to meet housing demand and searching for new partnerships between citizens, businesses and municipalities, a study focuses on "new open spaces" beyond officially recorded green and open areas — traffic junctions, rail embankments, industrial brownfields, parking lots, streets, sidewalks, private gardens, schoolyards, corporate green areas, delivery zones, courtyards, rubble sites, quays, allotment gardens, dikes, drainage channels, retention basins, bridges, building setback areas, and driveways. These spaces host trends such as urban gardening, urban exploration and parkour, and across four volumes on Hamburg the study examines their actual and potential contribution to open-space provision for the whole urban population, not only the inner city or young urban milieus.

Sylvie Lardon, Salma Loudiyi · OpenEdition (OpenEdition) · France

Set against the mid-21st-century demographic challenge, in which urban growth projections toward 2050 raise alarms over cities' food security, food sovereignty, and the sustainability of increasingly fragile territorial food systems, a French essay questions our capacity to think through change and devise new modes of action. The available abstract is truncated at this point and provides no further detail.

Monique Poulot · Bulletin de l Association de géographes français · France

Drawing on examples from the Île-de-France region and elsewhere in France, this piece discusses urban and peri-urban agriculture. It frames urban and peri-urban agriculture — once considered marginal and destined to disappear — as now an issue for both the sustainable city and sustainable agriculture, noting that most visions of the post-carbon 'city of tomorrow' describe a city made up of a concentration of compact urbanized zones alongside landscape fragments, each serving specific urban functions.

Malin Arvidson, Fergus Lyon, Stephen McKay, Domenico Moro · Voluntary Sector Review, Vol.4 No.1, pp.3-18 (Policy Press) · United Kingdom

A paper analysing how social return on investment (SROI) is used in the United Kingdom to conceptualise, measure and communicate the achievements of social enterprises and charities. It examines the quantification of benefits, the valuing of volunteering, and the ways judgement and discretion are exercised within an SROI exercise. It identifies a particular tension between the participatory element in designing each exercise and the use of its results for competitive funding, and proposes a research agenda on the contexts in which that discretion is applied. Abstract only was consulted.

Marit Rosol · Antipode · Germany (Berlin)

Documents how Berlin's municipal policy of promoting community gardening was an attempt to outsource public green-space maintenance to unpaid volunteers under 'roll-back'/'roll-out' neoliberalism. Based on empirical research, it shows the outsourcing strategy largely FAILED (volunteers could not sustain provision) while opening space for other private interests.

Eva Foos, Thomas Aenis, Julia Jahnke · GERICS Climate Service Center Germany (University of Oldenburg) · Germany

This paper discusses initial experiences from a German R&D network (INKA BB) developing capacity building programs for climate change adaptation in agriculture and horticulture. It uses two urban agriculture/gardening examples as case studies to discuss the strengths and weaknesses of development processes. The authors advocate for "learning chains" that enable lifelong learning and an action-oriented, participatory approach to foster mutual learning among partners from research and education.

David Tijero · Aldiri: arkitektura eta abar · Spain (Bilbao)

This article criticizes the municipal administration's attitude towards informal allotments on the outskirts of Bilbao. It analyzes the consequences of green space reclamation plans executed in recent years and advocates for policies promoting both formal and informal urban agriculture.

I. Karabozhilova, Barbara Wieland, Silvia Alonso, Laura Salonen, Barbara Häsler · British Poultry Science · United Kingdom (London)

A 2010 questionnaire survey of 30 backyard chicken flock-keepers in the Greater London Urban Area found that while chickens generally had conditions for natural behaviors, most owners did not comply with regulations on catering waste feeding. Disease prevention measures were rare, and a lack of avian and zoonotic disease knowledge among owners was observed, indicating implications for disease control.

Chiara Tornaghi · · United Kingdom

This academic-activist research on grassroots urban agriculture initiatives, focusing on four projects in Leeds, UK, found that local and regional institutions have limited ability to respond to these new demands. Planning traditions constrain institutions, failing to create flexible public spaces. Consequently, short-term solutions are found in "loose spaces" or ad-hoc negotiations, but these remain emergency or residual practices, highlighting challenges for urban public space management.
