A systematic evaluation in 2018 assessed the potential for low-tech, open-air, soil-based urban vegetable production across 840 cities in 30 European countries. The study used geospatial, demographic, and climate data under three land-use intensity scenarios. It estimated that 4551–7586 km² of urban land could yield 11.8–19.8 million tons of vegetables annually, roughly one-third of reported production, revealing substantial opportunities but also structural limits due to spatial variation.

This article explored how local currency activists in Monnaie Léman and the Brixton Pound envision sustainable futures centered on localism. Based on 19 interviews and ethnographic fieldwork in Brixton and Geneva, local currencies were examined as payments limited to specific areas. Activists promote ethical consumption, short supply chains, environmental awareness, economic education, and strong local communities in the short term. Long-term visions focus on localized economies, food sourced from community gardens, and green, compact, community-oriented small towns with well-developed pedestrian and cycling infrastructure.

This paper investigates how Community Supported Agriculture (CSA) initiatives in France navigate tensions between solidarity ideals and market expectations. Analyzing weekly CSA shares from twelve partnerships, including monitoring and producer interviews, the study found that CSA producers adopt hybrid strategies for economic viability and partial decommodification. The CSA share is presented as a material manifestation of this interfield position, stabilizing CSA as a hybrid field within alternative food systems.

This report presents sustainability impacts of Food Sharing Initiatives (FSIs) in Brighton & Hove, UK, combining data from CULTIVATE’s Food Sharing Map and submitted Sustainability Impact Assessment (SIA) data. FSIs are community-driven projects enabling collective food activities and skill exchange. The CULTIVATE project developed "The Toolshed" to assess FSI sustainability impacts across social, environmental, economic, and governance pillars. The report notes that the presented indicators are a subset of total impacts, and urban-scale estimations will improve with more SIA data.

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 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.

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.

Carla Galán-Guevara, Francesca Forno · Agriculture and Human Values · Italy (Trentino)

This qualitative study in Trentino, northern Italy, examined how alterity is conceptualized and enacted across nine Alternative Food Network (AFN) initiatives, using a decolonial analytical lens. Findings indicate that AFNs create meaningful opportunities for collective organization, ecological learning, participatory governance, and solidarity-based exchange, yet are simultaneously shaped and constrained by regulatory frameworks, certification regimes, economic pressures, and uneven organizational capacities. The study interprets AFNs in the Global North as spaces where partial openings and socio-ecological experimentation coexist with broader structures of coloniality, capitalist market relations, and institutional constraint.

An exploratory study conducted in allotment gardens in Berlin, Germany, from May to July 2019, investigated plant species richness and ecosystem services, particularly pollinator habitats and local food provision. Comparing 10 plots with varying management intensities, 376 plant species were identified. The study found that native species richness, weedy plant species richness, and the richness of species contributing to regulation and maintenance ecosystem services were significantly negatively correlated with garden management intensity. Urban allotments support pollinator populations due to a wide variety of nectar-producing plants, but this capacity is greatly affected by local gardener management.

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.

Julija Bakunowitsch · Urban Planning · Germany

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.

This chapter argues that power dynamics have received limited attention in sustainability-transitions research despite their centrality to lasting societal change, and introduces two frameworks -- "power to, over, and with" and "three relations of power" -- to analyze how power relations shift over time and are constituted. Applying these frameworks to a case study of community-supported agriculture in Portugal, the analysis shows how individual and collective agency, human and non-human interactions, and historical structures of social relationships shape opportunities and barriers for transitions. It concludes that more power-aware research incorporating non-Western and Indigenous epistemologies is needed.

According to the English Wikipedia article 'Manor Garden Allotments', the Manor Garden Allotments in London was a 4.5-acre (18,000 m2), 80-plot allotment site established in 1924 by Major Arthur Villiers. It was cleared in October 2007 to make way for landscaping of the London 2012 Olympic Park, and tenants were moved to a temporary site two kilometres away. Restoration on the original site and a 2.1-hectare provision of replacement plots were promised, but the successor Pudding Mill Lane allotments did not open until roughly four years after the Games ended.

The article on the VKSK, East Germany's national allotment organisation. Founded in Leipzig on 29 November 1959, it held the exclusive right to establish allotment sites. Membership stood at about 850,000 in 1962 and reached roughly 1.5 million by 1988. An extraordinary congress on 27 October 1990 resolved to dissolve the body with effect from 31 December 1990, and its gardeners and clubs passed into the all-German federation that followed.

The article on the German food crisis of 1916–17 during the First World War. It states that the Allied blockade reduced food supplies by 33 per cent and that the civilian diet fell to 1,560 calories a day by the summer of 1917 and to 1,000 calories a day in winter, against the 3,000 calories said to be needed by a healthy adult male. The name comes from the substitution of fodder swedes (turnips) for the failed potato crop. Female mortality is given as rising 11.5 per cent in 1916 and 30 per cent in 1917 against pre-war rates, and the historian G. J. Meyer is cited, quoting a Berlin physician, for the claim that eighty thousand children died of starvation in 1916. The historian Avner Offer is cited for the estimate that one-fifth to one-third of food could be obtained only through illegal channels.

This study examined how governance influences inclusion and long-term viability in seven community gardens in Portugal, Türkiye, Austria, Hungary, and Greece. Using a qualitative comparative design with 65 semi-structured interviews and policy analysis, findings showed that community gardens with stronger relational and procedural governance demonstrate higher levels of inclusion, particularly for women, migrants, and low-income residents. However, weak vertical policy integration across local, national, and European levels in most cases limits their broader systemic impact.

This article examines how Madrid's municipal markets are adopting new strategies linked to sustainable food systems in response to competition from supermarkets and online commerce. It highlights how citizen movements and municipal policies, including urban gardens and agroecological cooperatives, are fostering circular economies, responsible consumption, and urban resilience. The research positions markets as social mediators that connect diverse actors and balance economic interests with collective benefits, serving as instruments for regenerative urbanism and food equity.

This paper frames agroecological expectations for different urban forms based on Roland Fletcher’s model of settlement population scale and density. It hypothesizes that low-density urbanism allows labor-intensive land management, while high-density urbanism requires lower inputs per unit area and stress-tolerant crops. The study applies these expectations to early urban forms in western Eurasia, finding that diverse farming strategies in high-density areas and flexible low-density urban agroecology offer lessons for future urban farming.

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.
