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.

An ethnographic inquiry into a "refugees welcome" community garden in Germany offers power-critical reflections on social encounters, participation, inequalities, and the dynamics between 'the host' and 'the newcomer' in home-making. The study enhances understanding of how people with refugee biographies shape their surroundings and how communities navigate social heterogeneity. Specifically, it highlights inequalities and power dynamics within the context of home-making.

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.

Aspects of diversity, equity, and inclusion (DEI) in German alternative food networks (AFNs) were explored through literature, interviews, and one stakeholder workshop. The inquiry found that while women are better represented in AFNs compared to conventional food systems, groups may be disproportionately white and higher-class. Flatter hierarchies and general openness to participation, though supposed prerequisites for food justice, do not guarantee that traditional gender roles, passive exclusion, or social barriers are averted.

Helen Traill's book, "The Practice of Collective Escape," presents ethnographic work over six years in Glasgow, Scotland, following two community growing sites. The book critically examines urban agriculture projects as "Petri dishes for individual and community transformation," exploring concepts of inclusion, individual escape, and political activism, and highlighting social complexities and issues of inclusion and exclusion.

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.

The capacity of Family Allotment Gardens (FAGs) in Warsaw, Poland, to provide air-pollution filtration and microclimate regulation was quantified. Particulate matter, air temperature, and relative humidity were measured inside and outside three allotment complexes in autumn 2023. Results showed a moderate reduction in PM concentrations inside gardens (by about 2 µg/m³) and slightly higher humidity (2.1%). However, the cooling effect was weak (less than 0.3 °C), indicating a limited spatial range under autumn conditions.

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.

An outcome report from strategic workshops in Valladolid, Flanders, and Wrocław, engaging 33 diverse local stakeholders, assessed key policy and governance challenges facing urban agriculture. The most urgent and actionable priority identified across all three regions is the lack of coordination and knowledge sharing, underscoring a critical need to build resilient urban agriculture coalitions. To address broader structural issues like land access, stakeholders emphasized bridging the urban-rural divide, overcoming political short-termism, and establishing a shared understanding of urban agriculture's multifunctionality.

Magdalena Raftowicz, Mirosław Struś · Sustainability · Poland

An empirical study in Poland, based on a critical literature review and a 2024 CAWI (computer-assisted web interview) survey of CSA producers, examined whether social capital theory explains food producers' engagement in Community-Supported Agriculture (CSA) and whether this holds in practice. It found that social capital theory does explain the mechanisms underlying CSA engagement, with implications for local food system and small-farm policy, but that because of Poland's low level of social capital, the CSA model there remains only a niche complement to traditional agriculture, functioning primarily for a narrow group of socially and environmentally conscious consumers and small producer clusters.

A Wageningen University Science Shop report examines measures to improve water management for the "duinlandjes", centuries-old allotment gardens in the dunes near Egmond aan Zee, Netherlands, that form part of the Zeesdorpenlandschap cultural heritage. Commissioned by the Duinlandjesvereniging de Noord association, it investigated sustainable solutions from sociocultural, hydrological and ecological perspectives. The duinlandjes are currently experiencing flooding that makes cultivation very challenging. A stakeholder analysis found that while collaboration between the association and drinking water company PWN has advanced, interactions among stakeholders remain fragmented, and it calls for the province of Noord-Holland to take an active coordinating role. The hydrological analysis identifies winter precipitation surplus as the main driver of rising groundwater, projecting that climate change will bring wetter winters and drier summers with greater groundwater fluctuation, though long-term groundwater trends remain uncertain while winter/spring water excess will probably continue. The ecological risk assessment highlights the vulnerability of surrounding dune habitats, noting that draining and diverting excess rainwater can cause habitat degradation and increased drought stress.

This qualitative study examines a publicly funded urban gardening project in Dortmund, Germany, implemented as a labor-market activation measure on temporarily available land targeting employable welfare recipients. Drawing on interviews, participant observation, and document analysis, it combines the concept of "food justice" with valuation studies to analyze how labor, land, and exchange are valued in everyday practice. The findings reveal tensions between empowerment and dependency, care and control, and social recognition and material precarity: while participants experienced gardening as meaningful work and a source of social participation and belonging, these valuations remained bounded by welfare regulations, temporary land tenure, and charity-based food distribution. The study concludes that such temporary urban gardening projects function as sites of plural, negotiated valuation where justice is enacted only provisionally, through everyday practice, within the limits of welfare governance.

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.

An urban gardening project in a residential facility for up to 230 refugees in Germany aims to counteract precarious living conditions. While the garden offers a low-threshold space for knowledge exchange on resource-saving cultivation, biodiversity, and health promotion, this paper also reflects on the project's limits.

Mercedes Muriel Sáiz · Dialnet (Universidad de la Rioja) · Spain (Madrid)

This article examines the phenomenon of urban gardens from a socio-community perspective, based on a methodology combining a literature review and participant observation in the community garden Ensancha el huerto (Alcorcón, Madrid). The analysis shows that urban gardens operate as micro-ecosystems of mutual support and learning, but the study also highlights risks associated with institutionalization, commodification, and legal insecurity surrounding such initiatives.

This citizen science study analyzed inorganic pollutants in private garden soils in central Germany, including front and backyards. Elevated levels of lead and copper were found in one-third of the samples, and zinc in two-thirds. Chromium and nickel concentrations were also elevated in a quarter of the samples, with some readily available substances exceeding limit values.

This chapter analyzed the co-creation pathway of Nature-based Solutions (NBS) in the Dortmund Living Lab, focusing on urban gardening, food forests, and biodiversity. It critically illustrated missing dimensions that hinder innovation, such as business opportunities, legal frameworks, and planning conditions. These identified gaps indicate challenges in governance and implementation for social innovation through NBS.

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.

Dennis Raphael · Policy Press eBooks · Canada; United Kingdom

This chapter documents the growth of charitable non-governmental responses to food insecurity in Canada and the UK, including food banks, food diversion schemes, and community gardens. It is shown that these responses are problematic as they fail to address the economic and political causes of food insecurity. Further failures associated with charitable responses include the experience of stigma and degradation by food bank users and the promulgation of the belief that food insecurity is being addressed.

Mattia Andreola · Discover Sustainability · Italy (Trento)

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.

Ágnes Gagyi · Local Environment · Europe

This paper investigated urban gardening in an East European capital, focusing on institutional resources. The study found a clear relationship between a shortfall of institutional resources and the limited, conflictual promotion of urban gardens as sustainability tools. It argues that gardens' contradictions stem from the privatization of public functions, which has depleted institutions capable of implementing gardens as sustainability tools, instead outsourcing costs to garden communities.

A study analyzed the challenge faced by community urban gardens in Madrid, Spain, in remaining transformative spaces amidst an ecossocial crisis. These gardens are initiatives situated between community and public institutional management, with their expansion and institutionalization involving practices and relationships among diverse agents. The study points out the difficulty for these gardens to maintain their transformative role—updating community ties, reciprocity, and mutual care, and reformulating relationships with "nature" in the city and food supply—without being absorbed by market logics or marginalized into welfare or community volunteering spaces.
