Migration, participation and the making of homes narrations from a "refugees welcome" community garden in Germany
2026Berliner, Susanne · · Germany
An ethnographic inquiry into a "refugees welcome" community garden in Germany offers power-critical reflections on social encounters, participation, inequalities, and the dynamics between 'the host' and 'the newcomer' in home-making. The study enhances understanding of how people with refugee biographies shape their surroundings and how communities navigate social heterogeneity. Specifically, it highlights inequalities and power dynamics within the context of home-making.

2026Marta Melon, Tomasz Dzieduszyński, Piotr Sikorski, Beata Joanna Gawryszewska, Maciej Lasocki, Arkadiusz Przybysz · Sustainability · Poland (Warsaw)
The capacity of Family Allotment Gardens (FAGs) in Warsaw, Poland, to provide air-pollution filtration and microclimate regulation was quantified. Particulate matter, air temperature, and relative humidity were measured inside and outside three allotment complexes in autumn 2023. Results showed a moderate reduction in PM concentrations inside gardens (by about 2 µg/m³) and slightly higher humidity (2.1%). However, the cooling effect was weak (less than 0.3 °C), indicating a limited spatial range under autumn conditions.

2025Javier Rodrigo-Ilarri, Claudia P. Romero-Hernández, Sergio Salazar-Galán, María-Elena Rodrigo-Clavero · Sustainability · Spain (Valencia)
This article analyzes the impact of urban sprawl on the Valencia Plain aquifer system from 1990 to 2018 using the Weighted Environmental Index (WEI). Results show urban surfaces expanded by 70% and rainfed agricultural areas declined by over 59%, leading to a 9.2% reduction in environmental value (WEI decreased from 44.80 to 40.68). These changes threaten ecosystem sustainability and reduce the capacity to deliver ecosystem services.

2025Marina Abrão Ballak Dias · Revista Andaluza de Antropología · France (Paris)
This article explored how different conceptions of human-nature relationships shaped practices in two community gardens in Paris's Goutte d’Or neighborhood. Conceptions grounded in a human–nature divide prevailed, leading to a conservationist approach. Practices stemming from this perspective were found to be in constant tension with garden goals like increasing urban biodiversity and human socialization.

2024Ricard Segura, Johannes Langemeyer, Alba Badía, Sergi Ventura, Jaime Vila-Traver, Gara Villalba · The Science of The Total Environment · Spain (Barcelona)
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.

2024Catherine Oliver · Transactions of the Institute of British Geographers · United Kingdom (London)
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.

2022Jonathan Stubberfield, Mads Troldborg, E. Louise Ander, N.M.J. Crout, Scott D. Young, Rupert Hough · Agronomy · United Kingdom
This study investigated the influence of gardening routines on health benefits and risks among 120 urban gardeners in the UK. Participants showed a correlation between autumn/winter gardening activity and fruit/vegetable consumption, with higher physical activity levels and lower BMI than average. However, while gardening offers health benefits, the health risks from gardening on soils mildly contaminated with cadmium and lead may outweigh these benefits, requiring formal consideration within a risk management framework.

2021Marta Crispo, Miriam C. Dobson, Roscoe S. Blevins, William Meredith, Janice A. Lake, Jill L. Edmondson · Environmental Pollution · United Kingdom
Heavy metal (HM) and metalloid concentrations were assessed in 200 urban horticultural soils across ten UK cities. HM were found to be widespread, with most concentrations below UK soil screening values (C4SLs). However, 83% of lead (Pb) concentrations exceeded C4SLs, which is a significant concern. Bioavailable HM concentrations represented a small fraction (0.01–1.8%) of total concentrations, and black carbon (BC) and organic carbon (OC) were suggested to contribute to HM immobilization.

2021Magdalena Szczepańska, Ewa Kacprzak, Barbara Maćkiewicz, Lidia Poniży · Moravian Geographical Reports · Germany; Poland
A comparative study analyzed the use and development of allotment gardens (AGs) in Westphalia and Lippe (Germany) and Wielkopolska (Poland). AGs in Westphalia and Lippe are accessible and harmoniously integrated into the landscape, while AGs in Wielkopolska are less accessible, prioritize internal users, and do not always blend with their surroundings. The considerable freedom enjoyed by Polish plot-holders leads to a gradual marginalization of edible-plant growing.

2020Jeroen 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.

2020Lexi 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.

2019gökçe 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.

2016Ana Cristina Torres, Anne Caroline Prévot, Sophie Nadot · Letras Verdes Revista Latinoamericana de Estudios Socioambientales · France (Paris)
A study of 9 Parisian community gardens revealed the limitations of the dominant approach in conservation sciences and urban planning, which seeks to halt environmental deterioration by establishing an ethical basis of attitudes deemed appropriate for conserving a particular nature, by limiting human-nature interaction. Considering citizen subjectivities, the study offers perspectives to nourish conservation sciences and rethink cities.

2013Yves Cabannes, Isabel María Raposo · City · Europe
This paper conducted a comparative analysis of peri-urban agriculture in Lisbon and London to assess its contribution to migrant social inclusion and urban biodiversity. The study found that social inclusion patterns are city-specific; for example, Cape Verdean urban farming communities in Lisbon strengthen community bonds but do not necessarily lead to better integration into wider Portuguese society. Migrant urban farmers contribute to broadening biodiversity, primarily in Lisbon and to a lesser extent in London.
