This article explores the extent to which applying embodied, ‘skin in the game’ methods used in infrastructure activism (a contemporary art practice) can expand the toolkit of methods in action research on urban green infrastructure planning. It focuses on two cases of infrastructure activism: the Amsterdam Zuidoost Food Forest (VBAZO) in Amsterdam's South East, and the KRATER project in Ljubljana's city centre. Through discussing these projects, the article explores embodied research practices developed by infrastructure activists to change urban green infrastructures and researcher-actors’ perspectives.

A qualitative content analysis of interviews with active female respondents in community-supported agriculture, food cooperatives, and self-harvest gardens in Berlin Brandenburg revealed challenges faced by women in alternative food networks. Interviewees expressed optimism but emphasized the need for increased governmental support and community engagement, and the data highlighted demands for gender equality improvements and support mechanisms.

Anna M. Roodhof · Journal of Agriculture Food Systems and Community Development · Netherlands

To map and analyze food forestry (FF) in the Netherlands, a survey of 109 participants and interviews with five experts were conducted, identifying 231 food forests established since 2017. The survey data indicates that while FF initiatives are diverse in goals, few focus on profitability. Practitioners are largely homogeneous, consisting of university-educated individuals aged 40 to 60.

Silvia Gullino, Heidi Seetzen · · United Kingdom (London)

This ethnographic research in a former Victorian square in South London examined how residents transformed derelict spaces, including creating two community gardens, over three decades. The study found that while informal, bottom-up practices shaped a vibrant urban culture, the neighborhood is now undergoing progressive gentrification. This gentrification reflects trends in other London neighborhoods, posing challenges to community initiatives.

Concetta Cardillo, Orlando Cimino · Rural and regional development · Italy

An economic evaluation of urban and peri-urban agriculture in the Rome metropolitan area was conducted using Italian FADN data from 2008–2020 to analyze agricultural land use changes. The analysis revealed that farms are mainly specialized in arable land and herbivores, operated predominantly by men aged 40–65 with a high school education. While economic performance was good, it varied yearly, and few farms resorted to other gainful activities to increase income, suggesting greater diversification of agricultural activities is desirable.

This article discusses the prospects for developing local food systems (LPS) in St. Petersburg, focusing on urban agriculture (GSH) as a key component. The study analyzes current trends and statistical data to forecast GSH's impact on the city's environmental and socio-economic situation by 2030. Projections indicate that GSH can be an important tool for food supply and sustainable urban development, with advanced technologies and integration into urban planning as key development directions.

Véronique Saint-Gès, Bethsabée Warin, Antoine Jacobsohn · Sustainability · France

A study of two French public urban farms, the Potager du Roi in Versailles and the Cité Maraîchère in Romainville, using the concept of the triple-layered business model to examine their sustainability strategy through empirical case-study research. The evaluation of their economic, social, and environmental impacts shows their dependence on multiple interlinked public policies, and points to the justification for significant, recurring public funding on grounds of general interest.

Valeria Di Martino, Gian Vito Zani · Rivista di estetica · Italy

This paper examines the distinction between public goods and common goods (commons) as understood in economics and applies it to a typical public good — urban green areas. While public goods involve openness to all and state management, commons require management that is common yet still limited; the two also differ in the kind of agent involved, with public goods presupposing an aggregate of individuals and commons presupposing a plural subject capable of acting in concert to manage the good. After exploring this distinction in detail, the paper applies it to green areas in cities and shows the theoretical advantages of a commons-based framing, including through the concrete case of community gardens.

Michele Deri · Florence Research (University of Florence) · Italy

This paper examines the peri-urban agricultural park, an instrument that has gained significant importance in Italian territorial policy in recent years, as a tool for integrated governance of peri-urban territory and socio-ecological factors. Based on a desk analysis, it selects several major Italian experiences and presents an initial overview of the characteristics this tool presents in various contexts, in terms of both process and project. The paper highlights the relevance and diffusion of the instrument in public discourse and territorial governance practices, as well as the strengths, limitations, and critical issues the various cases present in operational terms, concluding that further exploration of its design and management characteristics as a connective element between planning and rural development is needed.

Henriette John, Martina Artmann · International Journal of Urban Sustainable Development · Germany

Based on a German case study, this paper introduces an integrative framework for evaluating the environmental, social and economic sustainability of urban agriculture, applying multi-criteria analysis via the Analytic Hierarchy Process combined with a participatory approach. Analyzing the examples of vertical farming and community-supported agriculture, the environmental dimension received the highest weight, followed by the social and then the economic dimension; among sub-criteria, species diversity received the highest weight and food quality and safety the lowest.

A chapter examines the role of technology across the European 'agrifood' system, an umbrella term for the agriculture, horticulture, food, and drink sectors. Placing the dysfunctional consequences of making economic growth the driver of food-system organization in historical context, it shows through a case study of a daffodil farm in South West England that when technology is deployed as an engine of efficiency, unbridled growth, and profit maximization, it vastly improves productivity through worker quantification—time, motion, and output tracking—while transforming worker-nature relationships in exploitative ways. By contrast, when used to prioritize non-exploitative, collaborative relationships, technology can support sustainable well-being and ecological production, illustrated through three alternative food network cases: a UK community garden, a UK Community Supported Agriculture scheme, and a network of social agricultural cooperatives in Italy.

AZOLLA Projects · Open MIND · Europe

This document, prepared under Activity 2.1 of the Carbon Farming MED project, defines the criteria for selecting pilot farms for a carbon-farming program across two Mediterranean regions, Italy and Spain. Farms practicing regenerative agriculture or agroforestry were required to meet mandatory conditions — legal compliance, access to internet and car transport, and the economic capacity to dedicate 0.5 ha to the study — plus preferable conditions such as soil free of heavy-metal contamination, historical soil analysis data, pollinator habitat and biological corridors, efficient water management, participation in farmers' markets or community-supported agriculture, a track record with circular-economy practices, and potential for scaling. Three farms in Catalonia and three farms in Spain were selected, with primary activities of viticulture, olive growing, horticulture, and agroforestry; on-farm data will be collected from these farms to monitor and validate soil organic carbon (SOC) content.

David Berná Serna, Sara Sama Acedo, Patricia Homs Ramírez de la Piscina · Revista Española de Sociología · Spain

Against the backdrop of the current eco-social crisis, this article analyzes the "eco-transformative capacity" of collective initiatives in three Spanish case studies: neo-ruralization and natural wine production in the Sierra Oeste de Madrid and southern Sierra de Gredos, agroecological supply systems in Catalonia, and community urban gardens integrated into a municipal program in Madrid. The analysis focuses on the motivations, challenges, and limitations agents encounter while practicing sustainable ways of dwelling, producing, and consuming, and on their relationship to public institutional agendas on eco-social transition.

A. Fanny, António Ferreira, Paulo Conceição · Urban Geography · France

This paper analyzes social housing strategies grounded in "right-sizing"—including demolishing vacant housing, consolidating urban development, and converting vacant land into community gardens—in two shrinking French cities, Le Creusot and Montluçon. The analysis found that while both cities implement some quantitative adjustment of housing supply to demand, their actual strategies are considerably more complex, combining multiple synergistic lines of action, and the paper highlights that right-sizing as an analytical concept remains constrained by austerity principles.

Elżbieta Skorbiłowicz, Piotr Ofman, Mirosław Skorbiłowicz, Marcin Sidoruk, Urszula Tarasiuk · Water · Poland

This study assessed heavy metal contamination in 96 surface sediment samples collected from urban, agricultural, and forested areas of the Bug River catchment in Poland between July 2018 and 2020, measuring metals (Zn, Pb, Cr, Ni, Cu, Fe, Mn, Cd) by atomic absorption spectroscopy and applying the geoaccumulation index (Igeo), contamination factor (CF), and pollution load index (PLI). Urban sediments showed significantly higher heavy metal concentrations than agricultural or forested areas, with cadmium reaching up to 2.5 mg/kg; the average Igeo for cadmium was 0.24 in agricultural areas and 0.15 in urban areas, while the highest PLI values, reaching a maximum of 0.33, occurred in urban areas, and statistical analysis showed both urban emissions and agricultural activities significantly influenced heavy metal presence in the sediments.

Gemma Nohales, Mike Stinavage · Zero Waste Europe · Europe

The EU mandated separate collection of bio-waste across all Member States from 31 December 2023, but a LIFE BIOBEST survey of 14 Member States found economic, legal/administrative, organisational and technical barriers present in 86-100% of sampled countries. Only 7 of 27 Member States fully met the 2020 recycling targets, and only 9 are on track for the 2025 targets.

In 2021 Liverpool City Council pledged to protect all 100 of the city's parks and green spaces — over 1,000 hectares of land — in partnership with charity Fields in Trust. By March 2024, only one, the park at Faulkner Square in the Georgian Quarter, had been formally placed in trust. The council said work was under way on 20 of the biggest and most strategically important sites, while local Friends groups expressed concern about the slow pace and development pressure.

Stadtverband Leipzig der Kleingärtner e.V. · Stadtverband Leipzig der Kleingärtner e.V. · Germany

A page in which the Leipzig city federation of allotment gardeners collects national figures for the organised allotment system: 20 state federations, more than 13,310 clubs, 503 regional, district and area federations, and about 890,000 members. Counting family and friends, roughly five million people use a plot, and the nationwide average wait is three years. On costs it gives an average ground rent of 0.18 euro per square metre per year, working out at about 66.66 euro a year for an average 370-square-metre plot.

Alves, D., Villar, I., Mato, S. · Environmental Science and Pollution Research (Springer), 31(7):9873-9885 · Spain / Europe

A study comparing methodology, bulking agents, and compost quality across community composting centres (CCC) and community gardens used by local governments to treat biowaste. It shows how population density and the presence of green areas determine the siting of decentralized local composting infrastructure.

De Simone M., Pradhan P., Kropp J. P., Rybski D. · Sustainable Cities and Society · Germany (Berlin)

Evaluates five urban space types (residential areas, allotments, rooftops, supermarket parking lots, cemeteries) and estimates the potential to produce a large share of Berlin's vegetable consumption locally.

Marini M., Caro D., Thomsen M. · Land Use Policy · Europe (Barcelona, Lyon, Trieste, Udine)

Reviews 83+ policy documents and surveys local managers in four EU cities. Finds land-use frameworks fail to prioritise urban agriculture, that only allotment gardens are meaningfully supported, and that local policies are formulated ad hoc outside any comprehensive UA framework, weakening effectiveness.

Polman Daniel, Bazzan Giulia · European Urban and Regional Studies · Europe (26 cities)

Uses fuzzy-set QCA across 26 European Milan Pact cities. Finds that the absence of governance practices—initiative mapping, integrated food strategies, and monitoring/evaluation—prevents most cities from becoming policy-innovative, so many signatories deliver only limited food-policy innovation.
