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.

A study developing a framework and overview of key factors, policies, and barriers associated with rooftop urban agriculture (RUA) integration, based on stakeholder perspectives in four European cities—Barcelona, Berlin, Bologna, and Paris—via a two-phase workshop and stakeholder survey. While education, environmental, research, technological innovation, food production, and social factors were found to play an important role in implementing RUA, the cost of water and pollution emerged as major contextual factors constraining it. Policies related to food trade and urban planning were the most limiting to RUA development, and major architectural and technical barriers were identified around building height limits, historical buildings, lack of specific building codes, and roof accessibility, with high infrastructure costs and policies prohibiting RUA product sales acting as economic constraints. The cities differed significantly in the perceived effect of urban policy on RUA diffusion and the perceived relevance of economic and pollution factors, and the study concludes that wider dissemination of RUA information and new or revised regulations and building codes are needed.

Paola Branduini, Elena Colli · Landscape Research · Italy

A qualitative sociological analysis examined a policy tool used by public landowners in peri-urban Milan, Italy, who introduced new lease agreements transferring the maintenance costs of built rural heritage to tenants, aiming to avoid degradation and add value to unused buildings. Analyzing the tool through the lens of social justice and its impact on quality of life, the study found that the same policy tool produces very different outcomes for landscape preservation and quality of life depending on the implementation strategy used, and on the elements of social justice considered along with contextual and individual characteristics.

Paola Clerino, Agnès Fargue‐Lelièvre · Sustainability · France

This study used a participatory approach with French urban agriculture stakeholders to identify sustainability objectives and 21 criteria for professional intra-urban farms. Six objectives were established, and agro-environmental and socio-territorial criteria were deemed more important than economic ones, with food production not being mentioned. A critical finding was that decision-makers focused more on projects' external sustainability and urban farmers' agricultural background, suggesting a reliance on farmers for internal sustainability rather than direct assessment.

Mosen Farhangi, Margherita Turvani, Arnold van der Valk, G.J. Carsjens · Sustainability · Netherlands (Amsterdam)

An ethnographic study in Amsterdam, Netherlands, analyzed barriers to the integration of high-tech urban agriculture (HTUA) into urban planning processes. The research revealed a lacking connection between planning actors and HTUA technology developers.

Ulrich Häpke · sub\urban zeitschrift für kritische stadtforschung · Germany (Ruhrgebiet)

While statistical data demonstrates the significance of urban agriculture in German cities and metropolitan areas, urban agriculture faces the problem of constant land loss despite its proximity to consumers. The example of the Ruhrgebiet highlights challenges such as land loss and high proportions of leased land, indicating governance issues faced by urban agriculture.

Carrie Ann Benjamin · Sociální studia / Social Studies · France (Paris)

This study examines community gardening and participatory urbanism in Paris, focusing on the Goutte Verte, a temporary nomadic community garden. The continued existence of the Goutte Verte is in opposition to the city's much-needed housing, with gardeners caught between a desire for green space and a demand for comfortable housing. Community gardens are shown to act as a material alternative to urban planning and governance that often fail to account for a "place to breathe" in the city.

Andrea Baier, Christa Müller · · Germany

This chapter discusses the results of semi-structured face-to-face interviews conducted in 2016 with activists in three urban community gardens in Bremen, Cologne, and Kassel, Germany. The study focused on the relationship between urban projects and municipal administrations. It showed that initiatives taken by grassroots activists to form collaborations with administrative actors are limited, though the traditional role of citizens can be extended in new local partnerships.

Jeroen Schütt, Bas Amelung · · Europe

This research, conducted by the Science Shop of Wageningen University and Research, estimated the monetary value of ecosystem services in the Lutkemeerpolder, Amsterdam, which is slated for conversion into a business park. The study identified food production, air purification, recreation, and the effect of greenery on housing prices as key services, valuing them at 1.5 to 8.6 million euros per year. These ecosystem service values were not considered in the original decision-making twenty years ago, leading to a recommendation to reconsider the development plan.

Luca Sára Bródy, Mandy de Wilde · Local Environment · Netherlands (Amsterdam)

Based on a qualitative study of 19 community gardening projects in Amsterdam, this research argues that community gardens function as “controlled space.” Various institutional governance actors, including local government, welfare organizations, green NGOs, and housing associations, exert varied levels of influence and control over the gardens. These relations both impair and enable the civic participation of gardeners, the inclusive potential of gardens, and an alternative, local food provision and distribution.

This study compared legal regulations for allotment gardening in Germany and Poland. Through analysis of legal acts, field research, and structured interviews, it was found that some provisions of legal acts in both countries are not strictly adhered to by users. In Poland, unclear provisions regarding crop cultivation have led to the replacement of the farming function by recreational and residential uses.

Lexi Earl, Pat Thomson · · United Kingdom (midlands in England)

This chapter examines a school garden with farm elements at a primary school in a deprived market town in the midlands of England, established as part of an 'eco-school' initiative driven by the former head teacher. The garden included various spaces like a farm, raised beds, a pond, and a herb garden, used for science learning and natural exploration. However, the study notes that the impetus for outdoor learning diminished after the initiating head teacher departed, as school priorities shifted due to other pressures.

Chiara Certomà, Lorenzo Chelleri, Bruno Notteboom · Urban Studies · Italy (Rome)

This paper investigates informal planning practices and "fluid governance" in urban public spaces, using the case of Parco delle Energie in Rome, Italy, and a comparative analysis of international cases. It found that politically progressive urban gardening challenges traditional governance networks and redefines public space functioning by transforming green spaces into food production and collaboratively managed areas through informal planning. This demonstrates that urban gardening worldwide challenges traditional planning perspectives and governance, turning citizens' dissensus into a productive force.

Rebecca St. Clair, Michael Hardman, Richard Armitage, Graeme Sherriff · Urban Studies · United Kingdom (Manchester)

This study, conducted in Wythenshawe, Manchester, UK, highlights the difficulties of collaboration among organizations in a lottery-funded urban agriculture project. Due to local authority cutbacks and a lack of funding, community groups and charitable organizations compete for space and resources, leading to a "siege mentality" where organizational self-preservation takes precedence over cooperation. This paradoxically results in groups with similar goals working against each other instead of collaborating.

gökçe öcal · Journal of Planning · Turkey (Istanbul)

This study focuses on the Roma Garden, one of Istanbul's last remaining urban gardens, within the context of "DIY urbanism." In Istanbul, historical gardens are threatened by municipal policies favoring urban development, leading to the formation of "DIY" urban gardens on public land since 2013. These gardens operate without legal ties to the local state, and the destruction of urban public space over the last decade is noted as having paved the way for DIY public gardens as spaces of solidarity and shared knowledge.

Robert Bartłomiejski, Maciej Kowalewski · Sustainability · Poland

This article discusses Polish urban allotment gardens (UAGs) as an alternative urban development framework, "Slow City." It notes that increasing problems of soil pollution, abandoned gardens, informal housing, and limitation of access to UAG green areas for other inhabitants reinforce the pressure to reduce the number of UAGs.

Carme Melo Escrihuela · International Journal of Sustainable Development and Planning · Spain (Valencia)

The evolution in the preservation, management, and planning of l'Horta de València, a historical Mediterranean huerta in Valencia, Spain, was assessed. It is argued that negative changes and impacts in l'Horta are not simply the outcome of global dynamics but result from the region's planning trajectory and landscape management approach. This approach has been shaped by a lack of territorial and supra-municipal perspective and the primacy of culture, identity, and heritage aspects over the landscape's productive dimension.

Sofia Nikolaidou · Manchester University Press eBooks · Europe

This chapter examines new forms of urban gardening, often involving informal and temporary reuse of vacant land, and their impact on urban green space governance and planning practices. Using examples from Greece and Switzerland, it highlights differences and similarities in practices, social and institutional contexts, and collaborative governance patterns. The study calls attention to the critical role of the temporary nature of these initiatives, which affects new configurations of urban green areas and public space, and related planning practices.

Marco Picone, Filippo Schilleci · Nova Science Publishers (Nova Science Publishers, Inc.) · Italy

A critical essay examining an urban-garden participatory process underway as part of Palermo, Italy's "Laboratorio Palermo città educativa," launched by the municipality in 2015 to convert abandoned or degraded public green areas into urban gardens for educational activities across all ages, in the name of neighborhood community reappropriation. The paper argues that in a context of austerity urbanism, it is easy for the municipality to exploit the absence of public investment to mobilize active citizens as protagonists of urban change, and that the idea of creating urban community gardens—like other recent slogans such as smart cities and creative cities—tends to become a universally praised, virtuous development model without scrutiny. It further notes that the lack of an effective regulation governing the use of public green spaces in the city continues to create obstacles to the solutions proposed by the thematic working table. The author concludes that field-based qualitative research is still needed to determine whether these reappropriation processes conceal neoliberal dynamics that delegate a false decision-making power to citizens while using them to fill current political vacuums.

Anna Trembecka, Anita Kwartnik-Pruc · Sustainability · Poland

This study analyzed data on the number and area of allotment gardens, their distribution across Poland, and the process of regulating the legal status of land occupied by allotment gardens. The research identified the number and area of family allotment gardens in Poland, along with the range and types of claims against them. The study found that land occupied by family allotment gardens requires protection and legal status regulation, which is difficult due to various entities submitting claims to these areas because of their attractive urban locations.

Lena Partzsch · · Germany (Freiburg)

This chapter examines agency and accountability in food localization projects in Freiburg, Germany, using two case studies: Regionalwert AG and Luzernenhof. Regionalwert AG defines agency through the market, while Luzernenhof, a CSA, relies on trust and charity. It was shown that while food localization is often portrayed as "best practice," it also implies decisions about alternatives, raising questions of agency and accountability.

A study on the use and value of green school grounds in developing countries was conducted across five schools in Podujevo, Kosovo. The findings revealed that the potential of green school grounds in most studied cases has not been utilized. Opportunities provided by the municipality and environmental NGOs are insufficient, suggesting a need to rethink the design and use of green school grounds in developing countries.

Matthew Reed, Evy Mettepenningen, Paul Swagemakers, M.D. Domínguez García, Ingrid Jahrl, Marlinde Koopmans · Urban Agriculture & Regional Food Systems · Europe

This paper examined urban food governance in four European city-regions: Bristol (UK), Ghent (Belgium), Vigo (Spain), and Zurich (Switzerland). The case studies demonstrated the role of citizens in urban food and the challenges this presents to city-region governance. Urban food activists, through horizontal networking and clear communication of demands, have raised significant questions about how cities are governed.

Marie Gisclard, Richard Raymond · Institut français d’études anatoliennes eBooks · Turkey (Diyarbakır)

This article examines the Hevsel Gardens in Diyarbakır, Turkey, which face sustainability challenges due to the city's growth and an asymmetric relationship where the city dominates the gardens. It highlights the unbalanced relationships between the gardens and the city, stemming from a lack of quality and quantity in water resources. The coexistence and competition of three socio-political projects, including centralized political networks and farmer-specific adaptations, call for a re-examination of this relationship and an alternative to the concentration of powers in the metropolis.

Michael J. Roy, Neil McHugh, Stephen Sinclair · Stanford Social Innovation Review · United Kingdom

Published 1 May 2018. The authors argue that Social Impact Bonds look like an ideology-neutral financing fix but carry significant technical problems and a troubling ideological shift. At the time of writing the UK had 32 SIBs; government had put in $28 million in 2012 and a further $113.4 million through the Life Chances Fund in 2016, with the UK market predicted to reach $1.4 billion by 2020, while the US had at least 10 SIBs and 19 more existed across 14 other countries. The Peterborough prison SIB's initial result was an 8.4 per cent reduction in reoffending. They find little evidence that SIBs encourage innovation, note the heavy administrative burden, and contend that prioritising investor returns over service users turns citizens into commodities.
