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 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 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.

The Parc Agrari del Baix Llobregat (PABL) is a leading European example of managing peri-urban agricultural systems in complex metropolitan areas of the Barcelona region. The park has established a multilevel governance framework that coordinates regulatory protection, agricultural production, and spatial development. The study emphasizes the importance of governance continuity in stabilizing agro-ecological practices, reinforcing short supply chains, and preventing land speculation.

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.

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.

Kinga Kimic, Magdalena Błaszczyk · Sustainability · Poland (Warsaw)

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 Rooftops for Equity and Sustainability (RT4ES) model, a GIS-based multi-criteria decision analysis, was applied to Padua, Italy, to map suitable urban rooftops for green roofs and photovoltaic systems. The model identified 11.67 km² of suitable rooftops across 29,493 buildings, with rooftop greening offering 10.94 km² of additional vegetated surfaces and rooftop PVs potentially generating 302% of municipal household electricity. RT4ES prioritizes underserved neighborhoods by integrating social and environmental vulnerability.

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.

A study developed a procedural approach to introduce agroforestry into urban planning and tested it in Sesto Fiorentino, Central Italy, involving 170 stakeholders in a questionnaire survey. Respondents preferred gradually introducing agroforestry into green infrastructure, with educational food forests and alley cropping being favored. While decision-makers incorporated agroforestry into city technical standards, urban planners were reluctant to include it at the strategic level in the city development plan.

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.

Helen Traill explores the social complexities of community growing projects based on six years of ethnographic work in Glasgow. She followed two community growing sites during the Brexit transition and the COVID-19 pandemic, examining concepts such as inclusion and exclusion, freedom, social justice, and political activism in urban agriculture projects. This study critically looks at gardens as sites for individual and community transformation.

Paul Miner · Journal of urban regeneration and renewal · United Kingdom

This paper evaluates the evolving role of Green Belt policy in England, arguing that both the designation and the land it protects are increasingly critical to addressing environmental, climate and public health challenges. It defines the extent and characteristics of Green Belt and other "countryside around towns" land, showing that these areas prevent urban sprawl, support nature recovery, provide public access to green space and sustain cultural landscapes, while highlighting mounting pressures including housing demand, weakened planning controls, losses in farming capacity and newly introduced "grey belt" policy reforms, and recommending measures such as reinstating strategic planning through Spatial Development Strategies, adopting a brownfield-first approach, prioritising environmental land management, and considering new Green Belt designations or expanded National Landscape protections.

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.

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.

The UK's Agricultural Relief lets qualifying agricultural property — farmland, pasture, stud farms, farmhouses and cottages among others — pass free, or partly free, of Inheritance Tax. Owner-occupied land (or occupied by a spouse/civil partner) must be held for 2 years, land let to others for 7 years, to qualify. Relief is 100% where the owner farmed the land themselves or it is let on a tenancy starting after 1 September 1995, and 50% in other qualifying cases. For deaths on or after 6 April 2026, the combined 100% Agricultural Relief and Business Relief allowed against an estate is capped at £2.5 million, with any excess receiving 50% relief instead.

According to English Wikipedia, the Water Tribunal of the Plain of Valencia was founded during the reigns of the Caliphs Abd-ar-Rahman III and Al-Hakam II, in 960 CE, as an institution of justice to settle disputes over irrigation water. It is made up of one representative (síndic) from each of nine Irrigation Communities, one of whom serves a two-year term as president. It meets every Thursday at Casa Vestidor on Plaça de la Mare de Déu in Valencia, and in 2009 was inscribed by UNESCO as intangible cultural heritage alongside the Council of Wise Men of the plain of Murcia.
