2025Juan Diego Torres, Sara R. Jaeger, Patricia Puerta, Amparo Tárrega · Applied Food Research · Spain
This study investigated Spanish consumers' perceptions of five lettuce cultivation systems using explicit and implicit methods with 105 participants. Local/small agriculture was most favorably regarded, while urban community gardens were perceived as less safe for lettuce production. High-tech greenhouses were considered safer but less sustainable, and vertical indoor farming elicited a surprise reaction due to low familiarity.

2024Melissa Anna Murphy, Pavel Grabalov · The Geojournal library · Europe
A study of urban agriculture initiatives in Aarhus, Denmark, and Rotterdam, the Netherlands, explored how municipalities facilitate urban agriculture and its performance in public spaces. It identified four public service trajectories: increasing access and animation, contributing to social services, producing and distributing food, and building communities. The study found that food production and social services may be little suited for urban spaces requiring high public access, although benefits can reach a broad public if localized and facilitated appropriately.

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.

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.

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.

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.

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).

2021Petra Hencelová, František Križan, Kristína Bilková, Michala Sládeková Madajová · Norsk Geografisk Tidsskrift - Norwegian Journal of Geography · Europe
This study aimed to identify the impact of visit frequency to community gardens in Slovakia on members' perception of membership importance, satisfaction with community relations, perceived improvement in social relations, and influence on quality of life. A mixed-methods approach, including a questionnaire survey and semi-structured interviews, was used. The analysis did not confirm a dependence between visit frequency and the gardens' impact on members' communities, and found no statistical relationships between the variables in the analyzed data set. However, members positively rated relationships within those communities.

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.

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.
