Things that endure: Community gardens and the post-work imaginary
2023Abigail Schoneboom, Daniel Mallo, Armelle Tardiveau · Journal of Classical Sociology · United Kingdom
This sensory ethnographic study, using pinhole photography, explored how time is experienced by unemployed volunteers at a community garden in the north-east of England. It found that the garden's ability to provide meaningful time is rooted in its food-growing and composting cycles, as well as enduring elements like mature trees and volunteer-made structures. The study argues that urban community gardens offer an "elongated present" that fulfills individuals and sustains community and nature.
CommunityWelfareOrganic cycleHealthAn original and efficient fertilizer for cherry tomato plants grown in urban agriculture: Feral pigeon guano
2023Chloé Duffaut, Florence Brondeau, Julien Gasparini · Urban Agriculture & Regional Food Systems · France (Ivry-sur-Seine)
This study tested the effects of feral pigeon guano as a fertilizer on cherry tomato plants in an urban environment on a rooftop in Ivry-sur-Seine, France. In June 2017, 15g of guano was added to 15 cultivation bags, while 15 control bags received only water. After 15 days, guano-treated plants were taller and tended to have more flowers, and the total number and mass of harvested cherry tomatoes were one to two times higher than the control. However, the average mass per fruit was not affected by the treatment. The study concluded that pigeon guano is an efficient local fertilizer for cherry tomato plants in urban areas.

Similar total SOC was found across all four systems. However, food forest soil showed similar long-term carbon storage to redwood forest, while pasture and agricultural fields stored less.
Organic cycleClimate changeFood loss and waste in community-supported agriculture in the region of Leipzig, Germany
2023Janine Voge, Till Newiger-Dous, Emily Ehrlich, Ulrich Ermann, D. Ernst, Dagmar Haase, Isabel Lindemann, Rebecca Thoma, Emilia Wilhelm, Joerg A. Priess, Lukas Egli · International Journal of Agricultural Sustainability · Germany (Leipzig)
This study assessed food loss and waste (FLW) and yields for one year in four Community-Supported Agriculture (CSA) initiatives in the Leipzig area, Germany, comparing them to reference data. Results showed that FLW during production, distribution, and consumption was on average 22–70% lower compared to reference data. Due to lower FLW, CSA initiatives could compensate for yield gaps of 32% on average, reflecting typical yield gaps between organic and conventional agriculture. Co-evaluation with CSA gardeners indicated that FLW could be further reduced at all stages.

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.

2022Wim van Dijk, J.E. Jansma, J. Broeze, J.J.R. Groot · · Netherlands (Amsterdam)
This chapter focuses on regional resourcefulness for food systems, arguing that urban areas are vital for closing nutrient loops to prevent resource depletion. Two case studies in the Metropolitan Region of Amsterdam (MRA) discuss phosphorus (P) flows, exploring the potential of a circular food system in Almere and quantifying actual P-flows across the MRA. The chapter concludes that a circular City Region Food System is technically feasible but requires a fundamental shift in the organization of food and waste systems.

2021Felipe Parada, Xavier Gabarrell, Martí Rufí-Salís, Verónica Arcas‐Pilz, Pere Muñoz, Gara Villalba · The Science of The Total Environment · Spain (Barcelona)
This study investigated the agronomic performance and environmental life cycle impacts of three different fertigation management practices (open, 30% recirculation, and recirculation with a further 15% fresh water reduction) for tomato crops in a rooftop greenhouse in Barcelona. All three practices resulted in similar yields, but the recirculation with reduced fresh water input was the most water-efficient, requiring 48.7 liters per kg of tomato. In terms of environmental performance, the recirculation practice showed the best performance in most impact categories, particularly in marine and freshwater eutrophication, with 44% and 93% fewer impacts than the open management.
