This article examines collective gardening spaces that have existed for decades across Lisbon, Portugal, analyzing the racialized urban geography revealed by the differing fortunes of makeshift gardens built by black migrants from Portugal's former colonies compared with white Portuguese community gardening spaces. Framing urban gardens as commons-in-the-making, it sets subaltern urbanism and the emergence of autonomous gardening commons against state erasure, overwriting, or top-down construction of commons. While urban gardening produces commons of varying persistence, the commons are shown to be closely entwined with processes of enclosure; the article argues these gardening commons are divergent, cannot be judged against any single abstract ideal, and ultimately do not share a "common" in common.

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.

HENKE Roberto, VANNI Francesco · Zenodo (CERN European Organization for Nuclear Research) · Italy

This 2017 article analyzed the role of peri-urban agriculture in Italy through a comparative study of seven metropolitan areas, using micro-data from the sixth Italian agriculture census. It identified six typologies of market-oriented farms. The study found that a significant share of farms in Italian urban poles are passively absorbed by urban expansion, indicating a challenge to their economic viability. However, the most reactive farms are diversifying and supplying social and economic services.

Hanna Hilbrandt · Urban Studies · Germany (Berlin)

This paper investigates the powers at play in informal housing practices and their regulation within Berlin's allotment gardens, where residency is prohibited. It argues that gardeners' ability to remain in these sites depends on their mediation of regulatory practices through relationships with state actors or institutional frameworks. This process highlights the co-construction of order and the establishment of boundaries for inclusion and exclusion.

Annalisa Lodigiani · · Europe

This research addresses the ineffective governance of peri-urban agricultural territory in Europe, noting that spatial planning lacks the tools to guide agricultural sector forces influencing landscape transformation. Public action, through agricultural and rural development policies, significantly transforms the environment and territory but does not directly target space. The study finds that the separation between spatial planning and rural development policy creates ineffectiveness and stalemates in governing peri-urban agricultural land, concluding that integration of these two fields is required.

Elsa Perroit · · France

This article reflects on the French agricultural model and the absence of urban agriculture from the "Etats généraux de l’Alimentation" (General Assembly on Food). Despite its multifaceted nature and role in urban food security, urban agriculture was relegated to a non-productive status, with its food functions disregarded. The article concludes that while urban agriculture possesses many qualities, it is not and will not be sufficient to feed urban areas.

Magdalena Szczepańska · Europa XXI · Poland

In Poland's Poznań agglomeration, agricultural functions tend to be marginalized in urban development concepts and documents due to urbanization. Despite their ecological, health, landscape, recreational, and social functions, family allotment gardens are alarmingly perceived as restricting urban spatial development. This study presented the current state of family allotment gardens in the Poznań agglomeration and offered recommendations for spatial policy.

Lidia Poniży, Kamila Stachura · Quaestiones Geographicae · Poland (Poznań)

This case study of Poznań, Poland, examines urban spatial policy regarding allotment gardens. It finds that despite their importance as green infrastructure, allotment gardens receive little attention in city plans and policies, and face threats from investment pressure due to an underestimation of their role. The study emphasizes that preserving these gardens relies on local spatial planning.

David Arredondo Garrido · ZARCH · Spain

This study analyzed four urban agriculture and gardening initiatives in the city centers of Seville, Barcelona, Madrid, and Zaragoza, Spain, over the last decade. These projects aimed to counteract the homogenization of urban historical landscapes and create spaces for culture and social interaction. Despite difficulties in their management and their minor impact, these interventions demonstrated a method for reconfiguring urban landscapes in abandoned central areas.

This study outlines a plan to assess air pollution risks in urban agriculture in the Netherlands, focusing on heavy metal (Cd, Hg) and PAK accumulation in spinach in Amsterdam urban gardens. It includes a literature review, policy maker interviews, and practical measurements of airborne contamination. The study aims to model different uptake routes by plants, but actual findings on contamination levels are not presented in this abstract.

Marlinde Koopmans, Daniel Keech, Lucie Sovová, Matthew Reed · Moravian Geographical Reports · Europe

This paper analyzed urban agriculture (UA) and place-making in Ghent, Brno, and Bristol, using a spatial lens across three case studies. It revealed that local authorities struggle to find space for UA, leading to its frequent, often temporary, emergence in marginal areas vulnerable to planning changes. The analysis exposed inherent tensions within UA, conceptualized as tensions between abstract space and concrete place narratives. It was suggested that UA, as a collective socio-cultural process, can transform functionally replicable spaces into unique places, contributing to place-making, and urban planning should secure physical spaces and create possibilities for local autonomous governance.

This qualitative investigation examined rooftop farming in Turin, Paris, and Rotterdam, focusing on local practices, policies, and stakeholder perceptions of sustainability and social impact. Findings reveal significant differences in governance: Turin's OrtiAlti project faced difficulties due to absent city strategies and policies, while Paris has a moderate number of rooftop farms with recent supportive policies. Rotterdam's Dakakker is a consolidated project, supported by local government through multi-stakeholder participation.

Nadia Tecco, Federico Cóppola, Francesco Sottile, Cristiana Peano · Future of food: journal on food, agriculture and society · Italy (Turin)

This paper, based on fieldwork in two urban communal gardens in Turin, Italy, examined the spatiotemporal dimension of urban gardening, focusing on governance and the impact of regulations. It found that urban garden management is problematic due to the complex relationship between gardeners and allotments. Local government and promoting associations face challenges in adapting to and managing the evolving phenomenon, encountering internal conservative resistance and external pressures for change. These governance aspects have not been sufficiently considered.

Informal vegetable gardens have proliferated in Barcelona's urban periphery since the 1980s, serving as leisure spaces and food sources, and are a relevant form of agriculture. However, these "unregulated" spaces are not considered in urban and peri-urban agriculture promotion policies. A GIS methodology mapped these gardens in the Barcelona metropolitan area for 2009 and 2015, showing an increase in occupied surface during the recent economic crisis. The study evaluates contradictions leading municipal managers to eliminate or regulate these informal spaces, attributing them partly to the subjectivity of the urban and peri-urban agriculture concept and its supposed multifunctionality.

This paper analyzed the evolution of peri-urban agriculture in Spain's Madrid and Oviedo metropolitan areas to identify revitalization opportunities. Using aerial images and cartographic bases, the study found that peri-urban agriculture has suffered from urban occupation and internal changes in crops and agricultural uses, experiencing a process of decline. Innovative initiatives are explored as potential revitalization opportunities.

Sertaç Güngör · Journal of Agricultural Faculty of Gaziosmanpasa University · Turkey (Konya)

This study investigated the current state of gardens in 7 nursery schools in Selçuklu district, Konya city, Turkey, regarding landscape design and space usage. The findings revealed that the nursery school gardens were not used effectively, lacked sufficient green space in their landscape design, and were not properly designed to contribute to children's mental and physical development.

Matthew Reed, Daniel Keech · Renewable Agriculture and Food Systems · United Kingdom (Bristol)

This study investigated how urban food activists related to the media, represented themselves, and how others represented their agenda during 2015 when Bristol was the European Green Capital. The research found that mass media primarily focused on topics other than food, and urban food was not a salient issue in their coverage. The self-representation of urban food networks revealed a narrow focus of interest, which may have contributed to a lack of connection between potential allies within the city, indicating limited connections of urban food networks to circuits of power and influence.

The first mass development of Aedes albopictus, likely introduced by trucks from Italy, was confirmed in an allotment garden area in Freiburg, Southwest Germany, in 2015. Surveillance confirmed a high infestation, with the container index exceeding 30% in August 2015. Control measures, including citizen awareness, environmental management, and Bacillus thuringiensis israelensis (Bti) tablets, successfully reduced the Aedes albopictus population, with the number of gardens without containers increasing from 17% to 35% by September 2015.

Stephanie Stephanie Kartika Lestari · · Europe

A case study of two urban farming organizations in the Netherlands developed a set of indicators to assess factors hampering the diffusion of radical innovation. Urban farming is characterized here as a radical innovation aiming for fresh and sustainable food supply in urban areas that has yet to achieve large-scale diffusion, and the study proposes a non-static conceptual model that lets commercial firms rationally assess barriers to diffusion and revisit their niche strategies as internal and external conditions change.

Marta Bożym · Ochrona Środowiska i Zasobów Naturalnych · Poland

A study measuring heavy-metal content (cadmium, lead, copper, zinc, nickel, chromium) in compost and resident earthworms sampled from home composters and allotment gardens in the Opole region of Poland. The compost samples themselves were not contaminated with heavy metals and stayed within Polish legal limits for solid organic fertilizers. However, metal accumulation in earthworms varied by metal: the bioaccumulation factor (BAF) was high for cadmium, lead and zinc, while no accumulation was found for nickel, chromium or copper. The authors conclude that earthworm species native to Poland, such as Eisenia fetida, can serve as potential bioindicators of metals in the environment.

A study evaluating the landscape condition of school gardens at 49 schools (30 primary, 19 secondary/equivalent) in the central district of İzmit, Kocaeli Province, Turkey, assessed for space-use profiles, landscape design components, and vegetal components (using a proportional range method for space use and frequency analysis for landscape and vegetal component data). The study found that landscape design of the school gardens is neglected, and that space-use rates fall far below standards compared with developed countries. Green space use was observed in only 43.33% of primary schools and 57.89% of secondary schools; the gap between the school with the largest green area and the one with the smallest was 313 times in primary schools and 57 times in secondary schools. Plant diversity in existing green spaces was found to be quite poor, with grass areas and flower beds rarely used. 93.34% of primary schools, which serve children of play age, had no play equipment areas, and 47% of secondary schools lacked multifunctional playgrounds suitable for basketball and volleyball. The study recommends treating school gardens as part of education and adopting a uniform standard for organizing spaces and components so all students have equal access.

A study focusing on peri-urban land in Gothenburg (Sweden), Copenhagen (Denmark), and Gent (Belgium) analyzed the relationship between peri-urban food production and urban resilience. It found that arable farming has declined in all three areas since 2000 due to urban expansion and recreational land use changes. While policies for farmland preservation exist, strategies for local food production are not expressed in current planning documents, and competing land uses and high dependence on global food systems reduce peri-urban food production and improvements in urban food security.

This paper examines community gardens in Glasgow, acknowledging their vulnerability to neoliberal cooptation where citizen work may alleviate state service provision. However, it argues that even with neoliberal practices, these gardens cultivate collective practices that suggest a progressively transformative polity. This form of citizen participation, termed "Do-It-Yourself" (DIY) Citizenship, encourages reconsideration of relationships and effective political practice.

A cross-sectional survey of 406 adults in four deprived urban communities in Scotland, UK, investigated the relationship between green space access and health outcomes. While the amount of neighborhood green space and access to a garden or allotment were significant predictors of stress, social isolation and place belonging were found to be the strongest predictors of stress in three communities and of poor general health in the least healthy community. Physical activity, winter green space visits, and home views also predicted general health.
