Urban Agriculture and Participatory Budgeting for Sustainable Cities: Evidence from Vegetable-Related Projects in Warsaw
2026Kinga Kimic, Magdalena Błaszczyk · Sustainability · Poland (Warsaw)
This study identified and assessed vegetable cultivation projects submitted to the Warsaw Participatory Budget (WPB) between 2015 and 2023. The research classified projects into six types and evaluated them across social, functional, ecological, and economic dimensions. The results showed that vegetable-related projects in the WPB were decidedly niche, with only 101 initiatives submitted and 31 implemented, primarily focusing on education for children rather than direct food access.

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.

2025Corina Başnou, Geovana Mercado, Åsa Ode Sang, Thomas B. Randrup, Verónica Fabio, Adrián Cabezas, Arnau Lluch, Marc Montlleó, Juan Miguel Kanai, Riccardo Saraco, Olívia Bina, Tom Wild · Nature-Based Solutions · Europe
An overview and guidance for air pollution indicators in nature-based solutions (NBS) for urban green planning and public health were provided, using three case studies in Europe and Latin America. The study noted that approaches including multidimensional indicators in research, planning, and policies are limited, and national standards for some air pollutants are missing with little evidence for health effect thresholds. Findings also indicated that knowledge of pollutant uptake in edible plants can suggest potential human exposure risks.

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.

2025Ágnes Gagyi · Local Environment · Europe
This paper investigated urban gardening in an East European capital, focusing on institutional resources. The study found a clear relationship between a shortfall of institutional resources and the limited, conflictual promotion of urban gardens as sustainability tools. It argues that gardens' contradictions stem from the privatization of public functions, which has depleted institutions capable of implementing gardens as sustainability tools, instead outsourcing costs to garden communities.

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.

2024Holger Braun, Dorothee Apfel, Benedikt Rilling, Carsten Herbes · Cleaner and Responsible Consumption · Germany
A study with 44 hobby gardeners in Germany found that substrates are not a major part of gardeners' social interactions, and price is the dominant purchase criterion for substrates, with sustainability not playing an important role. Although basic knowledge about peat is widespread, purchasing substrates is a utility-driven process with mostly passive information behavior.

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.

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.

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.

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.

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).

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.

2022Petr Klusáček, Stanislav Martinát, Klára Charvátová, Josef Navrátil · Land · Europe
This study investigated the drivers of de-agrarianization in post-socialist cities, using Brno, Czech Republic, as a case study through qualitative interviews. It found procedural issues in preserving architectural heritage during the redevelopment of a former Cistercian monastery site, often resulting in only fragments being preserved. The research also demonstrated a decline in the use of urban agricultural properties, which are rapidly transformed into new urban environments under intense urbanization pressures.

2021Fabio Amato, Lucia Simonetti · Journal of urban regeneration and renewal · Italy (Naples)
This paper focuses on the social urban garden in the Ponticelli neighborhood on the eastern outskirts of Naples, Italy, an area facing significant social and cultural problems including high unemployment and crime rates. The urban garden demonstrates how social cohesion can be built through urban agriculture and contribute to sustainability. However, the initiative risks remaining isolated and providing limited benefit to regional environmental sustainability efforts if not framed within an overall metropolitan strategy.

2020Paola Clerino, Agnès Fargue‐Lelièvre · Sustainability · France
This study used a participatory approach with French urban agriculture stakeholders to identify sustainability objectives and 21 criteria for professional intra-urban farms. Six objectives were established, and agro-environmental and socio-territorial criteria were deemed more important than economic ones, with food production not being mentioned. A critical finding was that decision-makers focused more on projects' external sustainability and urban farmers' agricultural background, suggesting a reliance on farmers for internal sustainability rather than direct assessment.

2020Martí Rufí-Salís, Felipe Parada, Verónica Arcas‐Pilz, Anna Petit‐Boix, Gara Villalba, Xavier Gabarrell · Frontiers in Plant Science · Spain (Barcelona)
This study investigated a closed-loop crop cascade system in a Barcelona rooftop greenhouse, using tomato leachates to irrigate five successive lettuce cycles. The results showed that low yields (below 130 g per lettuce plant) were obtained when the cascade system was used during the early stage of the donor crop, as the nutrient amount, especially nitrogen, was insufficient for the receiving lettuce crop. Additionally, electrical conductivity values became too high (near 3 dS/m) at the end of the donor crop cycle, indicating limitations in maintaining optimal conditions throughout.
