This study explored the production potential of urban farming in Olomouc, Czech Republic, using spatial analysis to identify suitable spaces. Results indicated that 408.04 hectares of currently unused land could be repurposed for urban farming, yielding 7,099.9 tons of vegetables. This production could meet 42.68% of the city's total vegetable demand, though detailed analysis is always necessary for specific areas due to varying potential.

A study analyzed the challenge faced by community urban gardens in Madrid, Spain, in remaining transformative spaces amidst an ecossocial crisis. These gardens are initiatives situated between community and public institutional management, with their expansion and institutionalization involving practices and relationships among diverse agents. The study points out the difficulty for these gardens to maintain their transformative role—updating community ties, reciprocity, and mutual care, and reformulating relationships with "nature" in the city and food supply—without being absorbed by market logics or marginalized into welfare or community volunteering spaces.

This paper presents the complete operational blueprint for the EArTh System, a community-led model designed to establish food sovereignty in post-industrial areas. The system integrates a decaying digital currency, democratic assemblies, and urban agriculture to create a parallel 'commons' for essential goods. Detailed as a pilot implementation for Glasgow East, UK, the document outlines its currency mechanics, legal structure, governance, and launch strategy.

This paper analyzes the case of community urban gardens in Madrid integrated into the Municipal Program of Community Urban Gardens. These initiatives are situated in the interstices between community management and public institutional management, generating new demands on the management of urban green commons and enabling forms of shared governance. The study reveals that these gardens face the challenge of maintaining themselves as transformative spaces without being absorbed by commercial logics or marginalized into welfare-oriented or community volunteer spaces.

This study presents a methodology for estimating potential biomass and carbon accumulation over a 40-year timespan for European afforestation activities, developed for the Life Terra project (LIFE19 CCM/NL/001200). It synthesized data from allometric equations, yield tables, national forest inventories, and national greenhouse gas inventory reports across four European biogeographic regions — Alpine, Atlantic, Continental, and Mediterranean — with the analysis focused mainly on timber plantations due to data availability and reliability constraints. Initial planting densities varied substantially across regions (1,869-7,702 trees/ha) and declined exponentially over time; by year 40, individual tree biomass estimates ranged from 0.08 to 0.20 t/tree with survival rates of 22.0-49.7%, giving stand-level biomass estimates of 54.7-232.6 t/ha. The estimates generally aligned with country-specific literature and IPCC default values but showed considerable site-to-site variation, and the study notes remaining uncertainties related to survival/mortality rates and climate change impacts.

In Vojvodina Province, northern Serbia — a rural region where 70% of the territory has been converted to arable land — researchers used QGIS to map areas suitable for implementing Nature-based Solutions (NbS), drawing on CORINE Land Cover, OpenStreetMap, data from the Institute for Nature Conservation of Vojvodina Province, and the EUNIS platform. The area suitable for NbS totaled 1,183,228 ha, or 55.74% of the province, with organic and regenerative agriculture projected to increase by up to 5%. Grazing was identified and mapped as a desirable grassland management option, potentially practicable on nearly 10% of the territory.

This study investigates the persistence of "gardening by the bloc," an informal urban gardening practice in the green spaces of collective housing districts in post-socialist Bucharest, Romania. Often dismissed in public discourse as a leftover of socialist-era survival strategies, the research instead reconsiders it as an everyday social interaction that supports communities amid urban transformation. Drawing on Tsing and De Angelis, the study frames the practice as a local form of "latent commons" reflecting broader socio-political shifts in a post-socialist city. Based on qualitative research, it documents how residents use, adapt and manage these green spaces and their relations with institutional actors under increasingly neoliberal governance, arguing that the overlap between a market-oriented regulatory project, inherited socialist structures, and collective spatial practices has shaped a distinct way of living together. As an emerging form of urban commons, gardening by the bloc can sustain shared communal practices against an increasingly individualized society and lay groundwork for bottom-up regeneration of housing estates, but the article also reveals contradictions inherent to latent commons, including internal tensions and ambiguities.

This study models spatial and temporal crop rotations on Amsterdam's rooftops using planting-structure optimization for crop rotation planning, to assess how much of the city's dietary demand for specific crop groups could be met by productive green roofs. Using average productive green roof crop yields and climatic variability from 2003-2021, it estimates Amsterdam's potential productive green roofs could achieve urban food self-sufficiency of 52% for selected crops (41-54% accounting for climatic and spatial variability), rising to 71% (50-71%) when the planting structure is optimized. Lettuce-broccoli occupies the largest productive green roof area, at roughly 100 hectares, and six vegetable types were found to match well with Amsterdam's dietary requirements.

A study in the Metropolitan Area of Barcelona, Spain, investigated the impacts of peri-urban agricultural expansion on the food-water-climate nexus using urban metabolism and atmospheric-biosphere models across four land-use scenarios. While expansion increased food production and irrigation water requirements, replacing natural non-forested and forest areas for peri-urban agriculture was predicted to reduce net ecosystem productivity by up to 18.5% and total carbon stocks by 3.3%. Irrigated peri-urban agriculture potentially reduced near-surface temperatures by 0.7°C, though reductions in the densest urban areas were minimal.

A two-case study in Warsaw and Poznań, Poland, explored the relationship between community gardens and cultural institutions, identifying factors that promote and impede their functioning. The study found that these gardens are characterized by a changing governance model, shifting towards a top-down approach where community members lack influence on strategic decisions. The involvement of cultural institutions, while facilitating longevity, may simultaneously disempower the gardens' viability.

Ayşen Çerşil, Esin Kömez Dağlıoğlu · İDEALKENT · Turkey

This study examines urban gardening as a form of food commoning, focusing on collective food production in urban gardens. It explores the role of common spaces and the social dynamics of urban gardening groups for urban food production, using the METU Garden (ODTÜ Bostanı) as a case study. The research aims to relate the social structures and spatial qualities of METU Garden to food commons theories and frameworks.

This article analyzes agriculture practiced in European cities and their surroundings, tracing its evolution from an essential food security practice in early cities to its decline after the First Industrial Revolution. It examines how the expansion of urbanization and structural transformations of the capitalist economy from the 19th century led to the reduction or disappearance of urban agriculture in major European cities. This shift resulted in a specialized food market supplied by distant producers, highlighting the changing relationship between agriculture, urban morphology, the labor market, and food supply.

This study explored two shared gardens in Rome and Strasbourg using qualitative research (participant observation and interviews) to highlight the diversity of political cultures animating these spaces. The garden in Rome showed a dynamic of public space appropriation, partly in conflict with local institutions, expressing the right to the city. In contrast, the Strasbourg garden revealed a dynamic of alliance between the association and institutions through the creation of a permaculture shared garden.

Amélie André · · United Kingdom

This case study of Letchworth Garden City examined the interplay between the town's layout, social practices, and governance supporting a local sustainable food economy. Food mapping and an ethnographical approach showed how Letchworth's masterplan provides a backbone for alternative food infrastructure, though the edible landscape is not always visible or effective for residents. Discussions with experts also pointed to a gap in coordination among key local stakeholders, which would be beneficial for improving the local urban food strategy.

This research addressed international and national policies, as well as related constraints and challenges affecting City Region Food System (CRFS) development in six European countries. Data was collected through desktop research, stakeholder interviews, and a workshop. The study found that planning laws restrict possibilities for food production in cities, and legal frameworks prevent the marketing and sale of food produced by non-commercial actors or informal farmers. It also identified a need to expand vocational training in the agricultural sector.

Claudinei da Silva Pereira, Antônio Nivaldo Hespanhol · Boletim Goiano de Geografia · Europe

This paper aims to understand agriculture practiced in cities and their surroundings in the European context, in terms of its purposes, relationships with the labor market, and food supply. Structural transformations of the capitalist economy since the 19th century led to the reduction or disappearance of urban agriculture in certain areas of major European cities. This resulted in the formation of a specialized food market, where merchants acquire food produced in areas increasingly distant from the final consumer.

Ophélie Véron · Antipode · Germany (Berlin)

This paper, based on activist ethnography in Berlin's community gardens, people's kitchens, and co-operative projects, explores how community food spaces reproduce, exacerbate, or dismantle power relations and socio-environmental injustices. It systematically examines exclusion and inclusion dynamics, arguing that diversity alone is not a sufficient indicator of social equity and can overshadow forms of injustice. The study exposes the complex, dual nature of Berlin's food activist landscape, where privilege and power contribute to social inequities.

This paper examines urban chicken-keeping in London, where urban spaces are transformed to accommodate chickens. It argues that the human-imposed design of urban barnyards is often impractical for chickens, leading to lawns being torn up, plants demolished, and vegetable patches consumed. Additionally, chickens are vulnerable to local foxes, highlighting that chickens' behaviors and territoriality often overflow their assigned space, challenging human design intentions.
