This theoretical study analyzes the potentials and barriers to the development of Community-Supported Agriculture (CSA) in Poland, drawing on existing research. It identifies key barriers to CSA development, including financial, legal, organizational, and social factors, which originate from both farmers and consumers. The ongoing land ownership concentration in Poland, fostering industrial agriculture, is contrary to sustainable development and EU agricultural policy, posing a significant barrier to CSA development, particularly for farmers.

This study investigated the conditions enabling urban agriculture (UA) at a 1 km² scale across 11 large European cities. The intercity model suggested that UA is more likely found in greener, central neighborhoods with lower property prices and lower proportions of locally born residents. However, there is not a consistent set of factors implying UA presence, suggesting other social and policy factors might be at play.

This paper explores the potential of Community-Supported Agriculture (CSA) in Germany, applying Erik Olin Wright’s concept of real utopia to assess if CSA challenges capitalist structures. Drawing on secondary literature, the study evaluates the desirability, feasibility, and achievability of CSA. The results suggest that CSA in Germany qualifies as a real utopia, but faces limitations to growth due to implementation constraints such as the need for additional market channels and access to land.

This chapter establishes a theoretical framework for examining the development of Community-Supported Agriculture (CSA). It argues that CSA aligns closely with sustainable development theory and should be regarded as an alternative to industrial agriculture. The analysis concludes that CSA constitutes a form of social and constructive innovation consistent with the sustainable development paradigm. However, the low level of social capital represents a key barrier to implementing the classical CSA model in Central and Eastern Europe.

This study examined the spatial-temporal transformations of peri-urban agriculture in the Metropolitan Area of Barcelona from 2003 to 2015, combining spatial analysis of land use changes with qualitative insights from stakeholder interviews and workshops. Results reveal that the significant decline of peri-urban agriculture is driven by a complex interplay of real-estate speculation, land fragmentation, infrastructure development, evolving land use policies, and ecological pressures from land abandonment and environmental protection. Despite efforts to preserve agricultural spaces, the decline of peri-urban farming remains significant.

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.

This study investigated the current state and professionality of biodiversity monitoring in food forest projects and influencing social-ecological factors through an online survey and interviews with German and Dutch experts. It found heterogeneous characteristics and professionality levels in monitoring activities, primarily due to context factors like actors, governance systems, and socio-economic settings. The professionality of monitoring depended on volunteer and expert availability and funding, indicating a lack of integrated, standardized, and systematic monitoring concepts and institutionalization.

Mesut YILDIZ · Agroecology and Sustainable Food Systems · Turkey (İzmir)

The Kadifekale Urban Orchard in İzmir, Turkey, was analyzed as a qualitative case study, showing that municipally supported urban agriculture functions as a relational public infrastructure reconfiguring women's labor, care responsibilities, solidarity networks, and public visibility. Based on one year of participant observation, in-depth interviews with 96 women, and focus group discussions, findings revealed women use the orchard to create space outside the home, build solidaristic ties, and increase public visibility. However, the case also revealed a persistent governance tension: municipal support is indispensable, yet women's influence over strategic decisions remains limited.

This 8-year case study tracked tomato cultivation in a rooftop greenhouse. Peak yield reached 49 g plant−1 day−1 in the 2023 cycle, but overall yield declined by 31.2% across the 8 years. Best water use efficiency reached 36.8 g/L under reduced irrigation. Solar transmittance dropped from 50.9% in 2015 to 46.4% in 2023 due to polycarbonate degradation, and life-cycle global warming impact rose from a minimum of 0.54 kg CO2eq to 0.94 kg CO2eq in 2023.

Published 5 April 2026 and updated 14 June 2026. Full cost recovery means funders covering not only a project's direct costs but its proportional share of overheads — rent, finance, IT, HR and chief-executive time. The article works through an example where two of ten staff (20 per cent of capacity) deliver a project, so £28,000 of £140,000 in annual overheads is added to £85,000 of direct costs for a £113,000 budget, and notes that overhead rates of 15–25 per cent are common sector guidance. It argues that accepting grants below true cost is a structural funding problem rather than a budgeting error, with consequences including staff burnout and governance risk, and notes that charity staff earn roughly 7 per cent less per hour than equivalent roles elsewhere in the economy.

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.

This study examined the market for allotment gardens in Warsaw, Poland, using a mixed-method approach including thematic archival analysis of regulations and hedonic regression modeling on posted offers. The findings indicate a poor transaction framework, pricing sensitive to legal and illegal private investments, and prevalent illegal rent-seeking on land. Additionally, increasing investment in allotment gardens was found to reduce biodiversity.

This study conducted three years of ethnographic research, including participant observation, in-depth interviews, and quantitative data analysis, on "NaturalMente in Trentino," a CSA initiative in Trento, Italy. The research revealed multiple lock-in points, indicating that CSA constraints stem from organizational inefficiencies, deeply rooted cultural and behavioral habits such as the use of private gardens or a preference for supermarket convenience, and rigid institutional frameworks like cooperative dominance in the local agri-food regime.

At the Christchurch College of Food Technology in New Zealand, researchers compared five growing systems -- rooftop container, raised bed, peri-urban orchard, rural orchard (reference), and heated greenhouse -- for avocado (Persea americana) cv. 'Hass' under simulated Bavarian Plateau conditions, using a randomized complete block design with four replications over three years (2020-2022). The rural orchard yielded highest at 22.3 kg per tree, peri-urban raised beds achieved 18.7 kg per tree using 56% less land, and rooftop containers (200 L pots) produced only 6.8 kg per tree, confirming that container culture is viable but yield-limited; rooftop systems had the lowest weed pressure, peri-urban orchards supported the richest arthropod biodiversity, and ISSR molecular markers confirmed genetic uniformity among grafted plants across systems, ruling out somaclonal variation as a source of the yield differences.

A study of Gothenburg, Sweden, examines the city council's shift over the past decade from associational (collective) urban gardening toward entrepreneurial gardening on municipal land, promoted through a scheme called "from garden box to hectare" that draws residents into entrepreneurial training while taking municipal gardening classes. Analyzing the consequences of this commodification of urban sustainability projects, the study finds that socio-economic resources and social relations both limit and strengthen entrepreneurial gardening practices and participants' quality of life, and that perceived competition among gardeners has turned urban gardening into a lonely, precarious, and individualized activity compared with the formalized associational gardening the municipality previously promoted. The finding points to a mismatch between the local government's sustainability visions and gardeners' actual experience.

A two-case study in Warsaw and Poznań, Poland, explored the relationship between community gardens and cultural institutions, identifying factors that promote and impede their functioning. The study found that these gardens are characterized by a changing governance model, shifting towards a top-down approach where community members lack influence on strategic decisions. The involvement of cultural institutions, while facilitating longevity, may simultaneously disempower the gardens' viability.

This case study of Letchworth Garden City examined the interplay between the town's layout, social practices, and governance supporting a local sustainable food economy. Food mapping and an ethnographical approach showed how Letchworth's masterplan provides a backbone for alternative food infrastructure, though the edible landscape is not always visible or effective for residents. Discussions with experts also pointed to a gap in coordination among key local stakeholders, which would be beneficial for improving the local urban food strategy.

This study investigated the impact of Community Supported Agriculture (CSA) structures on farm resilience among CSA farmers in Germany. A mixed methodology was applied, combining a case study with one CSA farmer and a survey of CSA farmers across Germany. The findings indicated that CSA provides mechanisms for improving farm resilience through increased income security, risk protection, market independence, and satisfaction. CSA farmers demonstrated a high level of perceived resilience compared to non-CSA farmers.

To map and analyze food forestry (FF) in the Netherlands, a survey of 109 participants and interviews with five experts were conducted, identifying 231 food forests established since 2017. The survey data indicates that while FF initiatives are diverse in goals, few focus on profitability. Practitioners are largely homogeneous, consisting of university-educated individuals aged 40 to 60.

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.

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.

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.

Bernd Bonfert · · United Kingdom; Germany

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 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.
