Assessment of heavy metal transfer factors from soil to edible crops in peri-urban agricultural lands
2024Elliot Buckminster, Charlotte Breckenridge, Thomas Sedgwick · International Journal of Research in Agronomy · United Kingdom
This research quantified soil-to-plant transfer factors for six heavy metals (Cd, Pb, Zn, Cu, Ni, Cr) in lettuce, spinach, and carrot across 20 peri-urban agricultural sites in Berkshire, UK, from 2021-2022. Cadmium exhibited the highest mean transfer factor (0.31), and at 4 of 20 sites, cadmium concentrations in lettuce exceeded the EU maximum limit of 0.20 mg/kg fresh weight. Soil pH was a strong predictor for Cd and Zn transfer factors, with TFs increasing below pH 6.0.

2024Anna 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.

2024Silvia 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.

2024Cosimo Dondini, Xavier Úbeda, Giacomo Certini, Marcos Francos · Journal of Soils and Sediments · Spain (Barcelona)
This study analyzed soils from ten urban gardens in Barcelona, Spain, with a special focus on possible contaminants. Irrigation water was also analyzed, and some of the waters contained a high concentration of salts and nitrites, which are listed as a pollutant. While three tests for heavy metals did not attest to significant pollution, other toxic elements not considered in this study could come from road transport gases or the port of Barcelona. Overall, the soil quality was concluded to be suitable for growing vegetables.

2024Alberto Matarán-Ruiz, David Fanfani, Josefa Sánchez Contreras, Miguel Ángel Escalona Aguilar · · Central America; Europe
This chapter examines bioregional food systems and territorialization processes in peri-urban agricultural areas, using three case studies from Central America and Europe. It notes that the historical co-evolutionary relationship between cities and surrounding farmlands weakened in modernity due to the global capitalist market, which reduced food to a commodity. The study highlights current problems while exploring how inherited relationships are being revived to adapt urban bioregions to climate emergency and resource scarcity.

2023Ayşe Öztürk Samur, Paulette Luff · İnsan ve Toplum Bilimleri Araştırmaları Dergisi · Turkey; United Kingdom
This phenomenological study investigated the views and experiences of 9 headteachers and 9 teachers from 6 preschool institutions in Turkey and England regarding outdoor learning. It found that in Turkey, school gardens, equipment, and time spent outside are insufficient compared to England. While family participation in outdoor learning is more common in Turkey, teachers and headteachers there experience greater family pressure concerning child safety, illness, and dirty clothes, and feel anxious due to a lack of classroom assistance. Both countries showed insufficient inclusion of outdoor learning in vocational and in-service training.

2023Lara Houston, Sara Heitlinger, Ruth Catlow, Alex Taylor · Policy Press eBooks · United Kingdom (London)
Workshops critically experimented with the possibilities and challenges of blockchain as an infrastructure for food abundance and reparative work, using fictional scenarios set in a London transformed into a city farm by 2025. This experimentation suggested that blockchain presents challenges to such restorative and sustainable work. For participants, reparation involved working in the aftermath of social and environmental collapse to bring into being more-than-human-value systems that radically decentered human knowledge and experience.

2023Michele D’Ostuni, C. Stanghellini, A. Boedijn, Leonardo Zaffi, Giuseppina Pennisi, Francesco Orsini · Sustainable Cities and Society · Netherlands (Amsterdam)
The feasibility of using urine and greywater streams as nutrient solutions in a theoretical model of Building-Integrated Agriculture in Amsterdam was evaluated. Results showed it is feasible to use urine and greywater as nutrient solutions; however, treated urine had higher macronutrient concentrations than literature fertilizer recipes, requiring dilution with increasing amounts of greywater to match N or P concentrations. Consequently, P deficiencies in plants or excessive N concentration were found in the final wastewater-based nutrient solution.

2023Wojciech Sroka, Piotr Sulewski, Jarosław Mikołajczyk, Karol Król · Agriculture · Poland
This study, based on a survey of economically successful peri-urban farms in Poland, identified success factors and major barriers to their development. The research shows a considerable convergence in business solutions in recent years, particularly in customer relationships and channels. According to respondents, the success of peri-urban farms is primarily determined by three groups of factors: motivation, diligence, and creativity; high quality of products and services; and cultivating deep bonds with customers. While farm managers indicated relatively few internal problems, urban pressure was considered the most significant external barrier to development.

2023Silvio Caputo, Victoria Schoen, Chris Blythe · Land · United Kingdom (London)
Data was collected from seven community gardens and one community farm in London, UK, during the 2019 and 2020 growing seasons using a citizen science approach, investigating crop yield, resource inputs, and social benefits. Results showed very mixed levels of crop and social productivity depending on organizational structure and agenda, with no clear pattern emerging. This study suggests that citywide productivity evaluations based on small data samples may not be reliable.

2023Runrid Fox-Kämper, Caitlin K. Kirby, Kathrin Specht, Nevin Cohen, Rositsa T. Ilieva, Silvio Caputo, Victoria Schoen, Jason K. Hawes, Lidia Poniży, Béatrice Bechet · Landscape and Urban Planning · Europe; United States
The relationship between urban agriculture (UA) and food-energy-water (FEW) nexus policies was analyzed using policy data from five case study cities in Europe and the U.S. (Dortmund, Gorzów Wielkopolski, London, Nantes, and New York City). An analysis of 78 policy documents and a Q-sort ranking by UA policy experts showed that the number, type, and degree of support for nexus policies varied among cities, and few policies (19) incorporated all elements of the nexus. Regulations were considered more effective at ensuring resource-efficient UA than incentives or awareness-raising policies.

2023Bernd Bonfert · · United Kingdom; Germany
This article investigates "network failure" and collaboration barriers within Community-supported agriculture (CSA) networks in the UK and Germany, using qualitative case studies. The study found that CSA networks function effectively at national and local levels but experience relative failure at the regional level. Regular barriers to collaboration arise from capacity limitations, member differences, and competition, which the networks are actively trying to address.

2023Susana Alves, Bahar Bașer Kalyoncuoğlu · Ecopsychology · Turkey (Istanbul)
This study explored the socio-ecological potential of urban agriculture in 10 family-related projects in Istanbul, where Bostans (historical urban vegetable gardens) are culturally significant. Despite their importance and UNESCO recognition, the planning and management of bostans have been hampered by rapid urbanization and a lack of integrative policies. Data from interviews, observations, and fieldwork highlighted the role of kinship in knowledge transfer and how farmers base activities on past-present affordances and future expectations.

2023Candan Türkkan · Moment Journal · Turkey (Istanbul)
This paper analyzes urban gardening practices in Yedikule Bostanlari and Kuzguncuk Bostani in Istanbul, examining the convoluted relationship between the food movement and urban agriculture. It argues that while urban agriculture initiatives are significant for generating community and proposing alternative uses for urban space, they do relatively little to mitigate the structural problems underlined by the food movement. As such, even though they are examples of urban agriculture in practice, their aspirations do not readily associate with those of the food movement.

2023Alioune Badara Dabo · Norois · France (Île-de-France)
This article analyzes how the public land tenure system, introduced in the 2018 "Agricultural Pact" in the Île-de-France region, articulates with local farming systems. Based on a qualitative survey conducted in the Green Belt area, the findings reveal that this land tenure system does not fully align with the strategies of farmers, particularly young people outside family farming who wish to establish themselves in agriculture, as they do not necessarily seek land ownership.

2022Angelica Mendoza Beltrán, Kelzy Jepsen, Martí Rufí-Salís, Sergi Ventura, Cristina Madrid‐López, Gara Villalba · The Science of The Total Environment · Spain (Barcelona)
This study mapped N2O emissions from peri-urban agriculture in the Metropolitan Area of Barcelona (AMB), Spain. Researchers spatially distributed factors like crop type, fertilizer use, and irrigation, creating N2O emission maps using crop-specific and Tier 1 IPCC emission factors (EFs). The study found that Tier 1 IPCC EFs estimated 15% more emissions (7718 kg N2O-N year−1) than crop-specific EFs (6533 kg N2O-N year−1) for the entire AMB, indicating higher emissions for rainfed crops with Tier 1 EFs and for irrigated horticultural crops with crop-specific EFs. The mapping helps evaluate spatial variability of key factors but carries uncertainties due to downscaling regional data.

2022Elizabeth Regier, Walter McDonald · Journal of Sustainable Water in the Built Environment · United States (Milwaukee)
This study monitored two bioswales treating runoff from an urban farm in Milwaukee, WI, United States, to assess their hydrologic and water quality performance. The bioswales effectively reduced runoff volume, peak flows, total phosphorus, and high concentrations of total suspended solids (TSS >25 mg/L), achieving a median 98% load reduction across all pollutants. However, they showed mixed results in reducing total nitrogen concentrations and TSS at low influent concentrations (≤25 mg/L).

2022Riccardο Petrini, Lisa Ghezzi, Simone Arrighi, Lisa Genovesi, Chiara Frassi, Luca Pandolfi · International Journal of Environmental Research and Public Health · Italy (Tuscany)
Trace elements were measured in soil and groundwater in the Fornaci di Barga urban area, Tuscany, Italy. Results indicate that Cu, Zn, and Cd are the main contaminants in surface soil, likely originating from airborne particulate matter deposition from metallurgical activity. Risk assessment considering soil ingestion and dermal contact exposure routes revealed that the cadmium Hazard Quotient approaches unity for children, and the cadmium risk-based concentration is only slightly lower than the maximum concentration measured in soil.

2022Andrew Millie · Crime Media Culture An International Journal · United Kingdom
This article considered guerrilla gardening, which involves taking on other people’s land without permission. A qualitative study of guerrilla gardeners from the North West of England found that guerrilla gardening is a normalised form of law-breaking. Despite not necessarily being to everyone’s taste and gardeners having an autocratic view of property, it is broadly accepted and welcomed, even by those who enforce the law.
Governance failureCommunityPolicyDIYVisionscapes: combining heritage and urban gardening to enhance areas requiring regeneration
2022Grete Swensen, Vebjørn Egner Stafseng, Véronique Karine Simon · International Journal of Heritage Studies · France (Bordeaux)
This comparative case study examines two regeneration projects, the Darwin Ecosystem Project in Bordeaux, France, and Dr. Dedichen’s Greenhouse in Oslo, Norway, to understand how heritage combined with urban gardening can enhance areas requiring regeneration. The study notes that conflicting economic, political, and cultural views are likely to affect the heritage discourse in marginalized urban areas. It describes how old buildings and historical fragments can be integrated into urban planning initiatives, with residents, artists, and citizen groups cooperating with planning authorities to transform neighborhoods.
Governance failureCommunityPolicyEconomicsHealthDisplaying geographic variability of peri-urban agriculture environmental impacts in the Metropolitan Area of Barcelona: A regionalized life cycle assessment
2022Angelica Mendoza Beltrán, Roc Padró, María José La Rota-Aguilera, Joan Marull, Matthew J. Eckelman, Jacob Cirera, Annalisa Giocoli, Gara Villalba · The Science of The Total Environment · Spain (Barcelona)
This study implemented an attributional, regionalized, cradle-to-gate life cycle assessment (LCA) to assess 14 environmental impacts of peri-urban agriculture (peri-UA) in the Metropolitan Area of Barcelona (AMB). It found that vegetables and greenhouses, the prevalent peri-UA land uses, had the largest assessed impacts among all peri-UA land uses. European NPK mineral fertilizer production to cover nitrogen demand for these crops drives all impacts. For fruit crops, on-site nitrogen emissions drive marine eutrophication impacts, and for irrigated herbaceous crops, phosphate runoff drives freshwater eutrophication impacts.

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.
