A study of two French public urban farms, the Potager du Roi in Versailles and the Cité Maraîchère in Romainville, using the concept of the triple-layered business model to examine their sustainability strategy through empirical case-study research. The evaluation of their economic, social, and environmental impacts shows their dependence on multiple interlinked public policies, and points to the justification for significant, recurring public funding on grounds of general interest.

Henriette John, Martina Artmann · International Journal of Urban Sustainable Development · Germany

Based on a German case study, this paper introduces an integrative framework for evaluating the environmental, social and economic sustainability of urban agriculture, applying multi-criteria analysis via the Analytic Hierarchy Process combined with a participatory approach. Analyzing the examples of vertical farming and community-supported agriculture, the environmental dimension received the highest weight, followed by the social and then the economic dimension; among sub-criteria, species diversity received the highest weight and food quality and safety the lowest.

A chapter examines the role of technology across the European 'agrifood' system, an umbrella term for the agriculture, horticulture, food, and drink sectors. Placing the dysfunctional consequences of making economic growth the driver of food-system organization in historical context, it shows through a case study of a daffodil farm in South West England that when technology is deployed as an engine of efficiency, unbridled growth, and profit maximization, it vastly improves productivity through worker quantification—time, motion, and output tracking—while transforming worker-nature relationships in exploitative ways. By contrast, when used to prioritize non-exploitative, collaborative relationships, technology can support sustainable well-being and ecological production, illustrated through three alternative food network cases: a UK community garden, a UK Community Supported Agriculture scheme, and a network of social agricultural cooperatives in Italy.

A page in which the Leipzig city federation of allotment gardeners collects national figures for the organised allotment system: 20 state federations, more than 13,310 clubs, 503 regional, district and area federations, and about 890,000 members. Counting family and friends, roughly five million people use a plot, and the nationwide average wait is three years. On costs it gives an average ground rent of 0.18 euro per square metre per year, working out at about 66.66 euro a year for an average 370-square-metre plot.

This study conducted an integrated environmental and economic assessment of organic peri-urban horticulture using primary data from a farm in Sheffield, UK. A hybrid life cycle assessment (LCA) found that the global warming potential (GWP) for case study tomatoes was 3.53 kg CO2-eq, which was 1.87 times higher than imported Spanish tomatoes. Economic analysis showed that the marginal increase in the prices of tomatoes and courgettes from the case study farm was 4.6 and 5.15 times less than the market prices, leading to the conclusion that the studied production system is economically and environmentally sustainable compared to the existing scenario.

J. L. Miralles i Garcia · International Journal of Environmental Impacts · Spain (Valencia)

In L’Horta de València, a historical agricultural area in Valencia, Spain, challenges and opportunities in peri-urban agriculture management were investigated. A semi-structured survey focusing on a SWOT analysis was administered to key specialists involved in the 2018 legislative protection and 2019 management plan. The study aimed to evaluate how newly implemented tools are rectifying identified issues, but the abstract does not present specific findings from the survey.

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.

This article systematically analyzes the potential for a coalition between Community-Supported Agriculture (CSA) and degrowth movements in Germany, drawing on social movement theories. It finds that the ideologies and political strategies of the two movements are not aligned, with CSA focusing practically on smallholder agriculture and degrowth abstractly on the growth-dependent economy. Scarce resources, differing internal organization, and CSA's lack of knowledge about degrowth are obstacles, though existing social ties and initial ideological alignment with sufficiency-oriented degrowth are noted.

Silvio 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.

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.

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.

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.

This paper proposes agroecological assessment as a tool for formulating evidence-based local food policies, adapting the Tool for Agroecology Performance Evaluation (TAPE) model on a sample of 20 farms in the city-region food system of Rome, Italy. Data analysis showed that agroecological principles are not fully adopted by the majority of farms considered in Rome. Additionally, farms with the highest agroecological level are mainly driven by social factors and have a lower propensity for innovation, which could hinder the transformation process of food systems.

An experimental indoor vertical farm urban-agriculture project involving 27 stakeholder groups was set up in a university building in Lisbon, Portugal in 2018 and closed in 2022; this study analyzed the governance dimension of the project's sustainability using role-constellation mapping of the stakeholder groups and force-field analysis across seven governance factors to understand why the project did not continue. It found that despite early positive outcomes across environmental, social and economic dimensions, the project failed to establish a network of stakeholders consistently engaged in governance from the outset, and that inadequate project culture and a lack of critical governance factors led to a failure to convey a sense of ownership to stakeholders, contributing to the project's closure.

Jesús Sanz Abad, Sara Sama Acedo, Gaël Carrero Gros · · Spain

Case studies of two cooperative enterprises (in finance and forestry) and one new urban commons — community gardens in Madrid — all located in Spain, were analyzed using ethnographic methods within the field of solidarity economy and commons. The analysis found tensions between the initiatives' economically and politically "transformative" aspirations and the reality of operating in a market-driven capitalist environment, alliances and tensions arising from interactions with established institutions, and dilemmas or conflicts between maintaining ideological coherence and extending the initiatives' social base.

This article examines raising the level of food security in a Russian region through the development of urban agriculture, using the Bryansk region as its example. It considers the mechanism for ensuring food security and identifies its key elements at the present stage, reviews approaches to assessing food security levels, and substantiates possible and significant criteria for such assessment. Using the methodology of D. G. Olovyannikov, it calculated the influence of a proposed measure on the food security level of the Bryansk region, though the abstract does not report the specific resulting figures.
