Sandra Schwindenhammer, Denise Gonglach · Politics and Governance · Germany

This qualitative and participatory case study in Germany examined the governance implications of an emerging technology in urban agriculture that connects wastewater treatment and agricultural production for urban hydroponics. The analysis found that while this technology has the potential to facilitate SDG implementation, it simultaneously creates new sector interlinkages between water and food, leading to policy demands that necessitate more integrated policymaking.

This paper focuses on the social urban garden in the Ponticelli neighborhood on the eastern outskirts of Naples, Italy, an area facing significant social and cultural problems including high unemployment and crime rates. The urban garden demonstrates how social cohesion can be built through urban agriculture and contribute to sustainability. However, the initiative risks remaining isolated and providing limited benefit to regional environmental sustainability efforts if not framed within an overall metropolitan strategy.

This paper analyzes how Incredible Edible Todmorden (IET), a community-led project, operated notions of sustainability through permaculture and urban farming to focus on community building and its impacts on education and local culture. The paper puts forth the argument that the discursive operationalization of sustainability can produce important effects in community building, education, and local culture at a local level.

Felix Zoll, Kathrin Specht, Rosemarie Siebert · Sociologia Ruralis · Germany

To investigate drivers of transformation in alternative food networks (AFNs) in Germany, interviews were conducted with producers and consumers in three AFN models: Community Supported Agriculture (CSA), food co-operatives, and self-harvest gardens, followed by qualitative content analysis. Participants in CSA and food co-ops reported a strong reconnection between producers and consumers, indicating transformative potential, while self-harvest gardeners primarily sought individual capacity building and access to their own garden. AFN participation was suggested to foster incremental transformation towards more sustainable food practices and a respective value system.

To understand the potential of the Community Supported Agriculture (CSA) model in Italy, two investigations were conducted in 2019 and 2020, analyzing structural and organizational aspects, and resilience during the COVID-19 pandemic lockdown. Findings indicate that CSAs represent a radically innovative experience capable of redefining production and consumption practices, demonstrating remarkable resilience due to their common value basis and strong interdependence and solidarity among members.

Mario Jordi Sánchez, Antonio Luis Díaz Aguilar · Sustainability · Spain (Seville)

Through observation and qualitative analysis of community urban gardens in southern Spain (Andalusia), this paper notes that the people who cultivate allotments within these community gardens attribute a wide variety of different meanings to their practices. This plurality of meanings moves beyond the rational-technical dimension of the act of growing, while at the same time redefining the act of consuming organic food, because of its connection with productive and social activities.

This study utilized the 'sustainable innovation journeys' concept to trace urban food initiatives in Rotterdam (Netherlands), Vigo (Spain), and Zurich (Switzerland) over a six-year period from 2013 to 2018. While micro-level innovation practices can induce sustainability shifts, particularly when aligned with policy interests, the study also observed potentially negative impacts due to a lack of alignment at the initiative or city-region levels.

A cross-sectional online survey of 477 UK adults (March-April 2020) investigated the role of home food growing during the early COVID-19 lockdown. Participants engaged in home food growing reported lower perceived food insecurity and higher well-being than non-growers. There were no differences in opinions of urban agriculture compared to pre-pandemic data from a separate sample (N=583).

Paul D. Jensen, Caroline Orfila · Food Security · United Kingdom

This case study used publicly available data to spatially analyze the urban food system of Leeds, UK, assessing its food security and resilience. The study found that while Leeds has a significant food production and provision system, it is not food secure in terms of providing sufficient energy or macronutrients, nor does it function equitably for all residents. Improving the system, including through urban farming, would require high investment, multi-sector cooperation, and strong governance.

Ronan Crézé · Lectures · Europe

This is a review of a book by geographer Flaminia Paddeu that presents an immersion into urban agriculture through observation of multiple field experiences, described as contributing to the institutionalization of urban agricultural commons. The book's central subject is the land, understood both as soil (urban and agricultural) and as the site hosting ecosystems. While this subject has already been explored by sociologists, agronomists, and anthropologists, the author develops her own reflection on it.

A cross-sectional online survey conducted during the UK national lockdown in March–April 2020 measured home food growing, perceived food insecurity, well-being and opinions of urban agriculture (UA). Participants were 477 UK-based adults (369 female, mean age 39.57 ± 13.36 years), of whom 152 had been engaged in home food growing before the pandemic; responses were compared with a separate sample collected before the pandemic (N=583). Participants who engaged in home food growing had lower food insecurity (U=19894.50, z=−3.649, p<0.001, r=−0.167) and higher well-being (U=19566.50, z=−3.666, p<0.001, r=−0.168) than those who did not grow food at home. Perceived food insecurity partially mediated the relationship between home food growing and well-being. Opinions of UA showed no difference compared with the pre-pandemic sample. Home food growing may have had a protective effect on perceived food security and well-being in the early stages of the pandemic, and opinions of UA remained positive and unchanged relative to pre-pandemic levels.

Elia Apostolopoulou · · Europe (Greece)

Focusing on the two largest Greek cities, Athens and Thessaloniki, this study examines why urban community gardening surged after the 2008 financial crash, drawing on urban political ecology, radical social and urban geography, and qualitative social research. Greece is treated as a distinctive case: it saw this post-2008 increase in community gardening without having a prior long history of the practice, unlike parts of the Global South. The author concludes that the creation of community gardens is tied to rising inequality in European cities in the aftermath of the 2008 crisis, functioning both as an act of disobedience against the grabbing of public land and as a demand for reclaiming the urban commons.

This paper analyzes local actors driving food-system transformation in the Lisbon Metropolitan Area (LMA), Portugal. It compares a 2014 questionnaire survey of planning officials with the discourses of 80 public- and civil-society-sector initiatives surveyed in 2019, characterizing the initiatives, examining how they are shaping new food planning agendas in the LMA, and drawing on a framework from the Food and Agriculture Organization (FAO) and the Resource Centres on Urban Agriculture and Food Security (RUAF) to identify lessons for future planning policy grounded in inter-municipal cooperation and continuous mutual learning.

Nora Gavare · Landscape architecture and art · Europe

In Sigulda, Latvia, the community garden "AUDZ," open to everyone, was created as a local, small-scale response to 21st-century problems including the depletion of natural resources, air pollution, rising industrial production, waste and an aging society. Designer Nora Gavare took part in an ERASMUS+ international training mobility visit on "Development of urban environment" in Hong Kong, where she gained insight into overpopulation, rapid urban growth at the expense of natural habitat, and rising food product demand. Photo mapping of Sigulda's public environment across different periods led to the conclusion that, given the town's rapidly growing population, fostering a sense of community and education processes is needed because opportunities for interaction among different social groups are lacking.

Carolina Neto Henriques, Teresa Costa Pinto, Pedro Costa, Teresa Marat-Mendes · Portuguese National Funding Agency for Science, Research and Technology (RCAAP Project by FCT) · Europe

A study of initiatives transforming the food system at both municipal and civil-society level in the Lisbon Metropolitan Area (LMA), Portugal, aimed to characterize these initiatives, examine how they are proposing new food planning agendas, and draw lessons for future planning policy. Its method compared a scenario from a 2014 questionnaire of planning officials with the discourses of 80 public- and civil-society-sector initiatives surveyed in 2019, using an analytical framework grounded in the FAO and RUAF (Resource Centres on Urban Agriculture and Food Security) recommendations.

Panagiota Kotsila, Isabelle Anguelovski, Francesc Baró, Johannes Langemeyer, Filka Sekulova, James J. Connolly · Environment and Planning E Nature and Space · Spain (Barcelona)

This paper analyzes nature-based solutions (NBS) as discursive tools that create an inviting space for nature's neoliberalization processes, examining two city-initiated projects in Barcelona, Spain: the Passeig de Sant Joan green corridor and the Espai Germanetes community garden. The study found that urban nature can serve elite economic players at the expense of widespread socio-ecological benefits. It also noted that outcomes regarding neoliberalism and its contestation were very distinct between the two projects due to different forms of governance.

Elizabeth Nicholls, Adrian Ely, Linda Birkin, Parthiba Basu, Dave Goulson · Sustainability Science · United Kingdom (Brighton and Hove)

A review and case study in Brighton and Hove, UK, examined the contribution of small-scale urban and peri-urban agriculture to sustainable food production. Findings showed these small, labor-intensive systems with high crop diversity can be highly productive, offering environmental and social advantages over industrial agriculture through minimal synthetic inputs and local consumption. However, significant knowledge gaps persist regarding productivity, economic impacts, pesticide use, and biodiversity implications.

Cristina Grasseni · · Italy, United States (Massachusetts)

This chapter compares and contrasts context-specific notions and practices of 'solidarity' within collaborative networks organizing alternative food procurement in Lombardy, Italy, and Massachusetts, USA, based on unpublished ethnography from 2011-2014. It juxtaposes Italian Solidarity Purchase Groups with the US solidarity economy network in the context of the Boston local food movement and Massachusetts community-supported agriculture. The chapter demonstrates how the meaning of solidarity in collective food procurement is context-bound.

Sarah Kumnig, Marit Rosol · · Europe

This chapter discusses two strategies for commoning land access in Europe, challenging private property and profit maximization amidst rising land prices since 2008. It presents two case studies: German cooperatives purchasing agricultural land for organic farmers, and the urban agriculture collective SoliLa squatting land in Vienna, Austria. Both cases aim to organize agriculture and food production collectively, differing in their engagement with formal markets and state but sharing the goal of enabling and preserving land access.

Rogelio Nogales Romero · · Spain (Granada)

This master's thesis outlines the process for creating and implementing a 3.8-hectare urban garden project in Casería de los Cipreses, Granada, Spain. The project aims to transform an abandoned historical site into sustainable, self-managed urban gardens for community building and agro-environmental education. It details the design, social and technical aspects, and the creation of an association to manage the initiative, adhering to municipal legislation and sustainability requirements.

Tezcan Mert-Cakal, Mara Miele · Agriculture and Human Values · United Kingdom (Wales)

This article examines Community Supported Agriculture (CSA) projects in Wales as social innovation, exploring their emergence, innovative role, and transformative potential. Based on qualitative data from four different CSA case studies in Wales, the research showed that Welsh CSA cases play distinctive roles in the social economy, satisfying needs for ecologically sound and ethically produced food and empowering individuals at a micro level. However, the paper argues that for CSA initiatives to become 'workable utopias', they need to overcome barriers preventing replication, participation in macro-level policies, and scaling up, particularly concerning economic sustainability and resilience on a small scale.

Irene Antoni-Komar, Christine Lenz · · Germany

This chapter discusses community building in sustainable food initiatives in Germany. Empirical data was collected through semi-structured interviews, participant observation, and action research with 27 practitioners from local food enterprises and initiatives, while quantitative data was gathered from surveys of members and customers. Findings indicate how participation in transformative enterprises is based on new forms of creative doing and collaboration, along with associated barriers and opportunities.

This study investigated a closed-loop crop cascade system in a Barcelona rooftop greenhouse, using tomato leachates to irrigate five successive lettuce cycles. The results showed that low yields (below 130 g per lettuce plant) were obtained when the cascade system was used during the early stage of the donor crop, as the nutrient amount, especially nitrogen, was insufficient for the receiving lettuce crop. Additionally, electrical conductivity values became too high (near 3 dS/m) at the end of the donor crop cycle, indicating limitations in maintaining optimal conditions throughout.
