Food sharing in Freiburg
2026Jennifer Lyons, Anna Davies · Zenodo (CERN European Organization for Nuclear Research) · Germany (Freiburg)
This report, part of the CULTIVATE project, assesses the sustainability impacts of Food Sharing Initiatives (FSIs) in Freiburg. It combines insights from CULTIVATE's Food Sharing Map with sustainability impact assessment (SIA) data submitted by FSIs, estimating impacts across environmental, economic, and social pillars. The report notes that the presented indicators are a subset of total impacts and estimations will become more accurate as more FSIs submit SIA data.

2025Trenkner M., Kiesel A., Bauerle A., Lewandowski I. · Biofuels, Bioproducts and Biorefining · Stuttgart, Germany
Analyses the technical potential of urban biorefinery concepts for recycling plant nutrients from waste streams and wastewater in a German metropolitan region to close the urban-rural nutrient loop.

2025Simona Gavrilaş, Oana Brînzan, Radu Lucian Blaga, Maria Sinaci, Eugenia Țigan, Nicoleta Mateoc-Sîrb · Agriculture · Europe
This study investigated the correlations between perceived benefits of urban agriculture (socialization, recreation, and food waste avoidance) and education levels and financial situations among 648 inhabitants of western Romanian towns, using data collected via an online questionnaire. Analysis showed that a high level of education leads to increased belief in urban farming's contributions to improving residents' socialization and recreation. Income level also significantly shaped opinions regarding urban agriculture's contribution to increased recycling.

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.

2022Rüschhoff J., Hubatsch C., Priess J., Scholten T., Egli L. · Renewable Agriculture and Food Systems · Germany (Leipzig)
A Leipzig case study assessing food self-sufficiency potential, finding that combining organic agriculture, reduced food loss, and a more plant-based diet could reach a mean self-sufficiency level of about 95%.

2020Sovová L., Veen E.J. · Sustainability (MDPI), 12(12):5134 · Europe
A comparative study of food self-provisioning in allotment gardens in the Netherlands and Czechia, drawing on social practice theory. It argues self-provisioning is neither merely a poverty response nor a trend, holding significant potential for food provisioning that can be supported within alternative food networks and urban sustainability frameworks.

2020Fattibene D., Recanati F., Dembska K., Antonelli M. · Resources · Europe (40 cities across 16 countries)
Presents a framework to assess urban food waste policies and initiatives across 40 cities in 16 European countries, linking policy types, intervention areas, and actors to the Sustainable Development Goals.
Food lossPolicyDoes participating in community gardens promote sustainable lifestyles in urban settings? Design and protocol of the JArDinS study
2019Marion Tharrey, Marlène Pérignon, Pascale Scheromm, Caroline Méjean, Nicole Darmon · BMC Public Health · France
The JArDinS study is a quasi-experimental protocol designed to assess the impact of community garden participation on the adoption of more sustainable lifestyles in Montpellier, France. It will recruit 80 new gardeners and 80 matched control volunteers, measuring lifestyle sustainability across social/health, environmental, and economic dimensions over one year using food supply diaries, accelerometers, and questionnaires. The study aims to compare outcome changes between the groups to evaluate causality.
CommunityHealthFood lossEconomicsNet Yield Efficiency: Comparing Salad and Vegetable Waste between Community Supported Agriculture and Supermarkets in the UK
2019N. R. Baker, Simon Popay, James Bennett, Moya Kneafsey · Journal of Agriculture Food Systems and Community Development · United Kingdom
This paper introduced "net yield efficiency" (NYE) to compare food system performance by accounting for yields, loss, and waste. A UK case study compared fresh vegetable and salad waste between a community supported agriculture (CSA) scheme and the supermarket system. The study found that the CSA system wasted only 6.71% by weight across all stages, dramatically outperforming the supermarket system which wasted 40.7–47.7%. These findings highlight significant differences between the systems and suggest NYE offers a more accurate measure of food system performance.
