This bibliometric review analyzes the systemic structure of multifunctional agriculture (MFA) and its relationship to sustainability, based on a sample of 432 documents published on the Web of Science platform. Using Bibliometrix and VOSviewer to map scientific collaboration networks, the review identified the authors, journals, and countries shaping the current knowledge structure and four thematic clusters: (a) MFA and sustainability, (b) ecosystem services and biodiversity, (c) European public policies, and (d) governance and urban agriculture. It concludes that, despite an increase in publication rates, research remains concentrated in Europe with few collaborative networks across disciplines, indicating that SDG 17 (partnerships) is not being achieved.

This paper proposes the concept of a "wastewater use basin" as a smaller-scale working unit than a traditional river basin, aimed at better managing sewerage-network water and urban stormwater in semi-arid and arid regions where water scarcity drives competition among urban, agricultural, industrial, and tourism demands. It is a geographically-focused proposal for integrated management of wastewater and stormwater that ultimately reaches a treatment plant for treatment and reuse. The study area is the southeastern Iberian Peninsula, Spain — the Campo de Cartagena–Mar Menor district (Murcia) and the Vega Baja district (Alicante). Analysis of recent torrential rainfall episodes in the Segura river basin found a clear tendency for these episodes to occur in coastal and pre-coastal areas, meaning the water does not reach the headwaters where the reservoirs are located. Based on the capacity of existing and planned environmental tanks, the study estimates that four cubic hectometers of additional water could be incorporated into the hydrological planning of the Segura basin. It concludes that rainwater collection adds a supplementary water volume that complements resources from treatment plants, serves as an adaptation measure to climatic extremes such as droughts and floods and to climate change, and supports circular management of water resources.

A discussion piece examines vineyards as a specific form of urban agriculture, focusing on their spatial and functional dimensions through a case study of Vienna. Drawing on data from the Austrian Wine Marketing Board and field observations conducted in April 2022, it analyzes Vienna — described as "the king of urban viticulture" — to determine the spatial distribution of vineyards within the city, their production structure, and the functions they perform. It concludes that viticulture and winemaking in Vienna display a multifunctionality that combines production with recreational, tourist, landscape and cultural functions, which contributes to the preservation of vineyards within the city's space.

A quantitative analysis of how the EU Common Agricultural Policy affects rural employment, GDP and poverty in the Baltic states, showing that higher rural employment promotes rural economic growth.

Michael Carriere, David Schalliol · Journal of Urban History · United States (Milwaukee)

This historical essay documents the history of urban agriculture in Milwaukee, Wisconsin, complicating the "declensionist" narrative of the twentieth-century U.S. city. It argues that food production played a significant and often overlooked role in Milwaukee's economic, social, and spatial development, even during industrial expansion. The authors show that urban agriculture remained a viable tool for urban redevelopment, used by both public- and private-sector actors well into the twenty-first century.

This chapter focuses on regional resourcefulness for food systems, arguing that urban areas are vital for closing nutrient loops to prevent resource depletion. Two case studies in the Metropolitan Region of Amsterdam (MRA) discuss phosphorus (P) flows, exploring the potential of a circular food system in Almere and quantifying actual P-flows across the MRA. The chapter concludes that a circular City Region Food System is technically feasible but requires a fundamental shift in the organization of food and waste systems.

This paper discusses the meaning and role of social solidarity in modern societies, based on Emile Durkheim's theory of social solidarity, focusing on solidarity-based agricultural cooperatives as alternative economic models against capitalist/liberal systems. The paper demonstrates that modern societies can successfully present solidarity-based alternative economic models, aligned with the spirit of social innovation, as a reaction to traditional capitalist production systems amidst eroding solidarity norms. Characteristics of solidarity agricultural cooperatives operating in Community Supported Agriculture (CSA) are introduced, confirming Durkheim's thesis that social solidarity can emerge through collective movements even within a capitalist-liberal system.

A preliminary assessment of the adaptability of 15 Italian native and non-native Vitis vinifera L. cultivars to urban environmental stressors was conducted at the Botanical Garden of Rome during the 2021 growing season. Researchers evaluated leaf chlorophyll content, stomatal conductance, chlorophyll fluorescence, and spectral signatures. Native cultivars showed medium-high leaf chlorophyll content (>350 mol m−2), good photosynthetic efficiency (QY > 0.75), and optimal stomatal behavior under drought stress (200 > gs > 50 mmol H2O m−2 s−1), indicating site-specific resistance and resilience to urban conditions.

This comparative case study examines two regeneration projects, the Darwin Ecosystem Project in Bordeaux, France, and Dr. Dedichen’s Greenhouse in Oslo, Norway, to understand how heritage combined with urban gardening can enhance areas requiring regeneration. The study notes that conflicting economic, political, and cultural views are likely to affect the heritage discourse in marginalized urban areas. It describes how old buildings and historical fragments can be integrated into urban planning initiatives, with residents, artists, and citizen groups cooperating with planning authorities to transform neighborhoods.

Fiona Greenland · Social Forces · Germany (Ruhr valley)

This review of "How Green Became Good" by Hillary Angelo examines why urban greening became a public good, challenging conventional accounts. Tracing urban greening in Germany's Ruhr valley, Angelo argues that greening constructs not only physical spaces but also social imaginaries, where nature as a public good is mutually constitutive with economic production needs, rather than being in opposition. The work shifts the understanding of urbanized nature from inherently contentious politics to a socio-cultural process of urban modernization.

This study investigated the drivers of de-agrarianization in post-socialist cities, using Brno, Czech Republic, as a case study through qualitative interviews. It found procedural issues in preserving architectural heritage during the redevelopment of a former Cistercian monastery site, often resulting in only fragments being preserved. The research also demonstrated a decline in the use of urban agricultural properties, which are rapidly transformed into new urban environments under intense urbanization pressures.

A quantitative study (n=790) among Community-Supported Agriculture (CSA) members in Germany used a multiple regression model to identify factors predicting trust in CSA and its farmers. The analysis found that "reputation," "supply of information," "direct social interaction," and "duration of CSA membership" influenced trust. Conversely, "certification status of the CSA farm" and "attitudes toward organic certification" did not significantly predict trust.

Changes in the ways of using plots in allotment gardens in Poland were investigated. A direct inventory and questionnaire survey were conducted among users of five gardens: one in Łódź and four in its suburban zone. Analysis revealed that the farther from the center of Łódź, the less dominant the leisure and recreational model was. Additionally, users' professional activity and age were identified as socio-demographic features currently determining the way plots are used in these gardens.

A questionnaire survey of 203 allotment garden owners in three Silesian cities, Poland, explored perceived functions and importance during the COVID-19 pandemic. Respondents over 61 years observed a generational shift from food cultivation to recreation, while no age group noted technological progress or new crops. Allotment gardens were crucial during the pandemic as a private, restriction-free space and a coping strategy for lockdown stress.

Anna Kapała · Laws · France

This study aimed to identify legal instruments implemented in France that support short food supply chains and local food systems. The research identified these tools from various domains and levels, including national laws, government policies, and local government initiatives, analyzing them in relation to forms of short supply chains like direct marketing, producer stores, basket systems, urban agriculture, and public catering deliveries. The French instruments were found to be multiple, diverse, mostly innovative, and to consider social, environmental, and solidarity values.

A report examining the practice of sustainable management and growth, taking the 1987 UN report as a starting point, through a case study and situation analysis of a nascent, innovative Hungarian agricultural start-up, examining how financial accounting data can be used to measure and interpret the sustainable growth rate (SGR). Drawing on case and situation analysis from the Hungarian consulting sector, the study applied a quantitative technique using a self-developed financial diagnostic and value-creation expert system called FINel. Alongside the theoretical conception of sustainable management and SGR, the report demonstrates its application in business practice, presenting sustainable finance adapted to corporate life cycles as the basis for sustainable corporate management in a holistic approach.

This study used the digital agricultural geographic information system AGRO-GIS to calculate and predict potential urban agriculture from abandoned horticultural lands and greenhouses in urban areas, applying binary logistic regression to identify determinants of abandoned horticultural land and greenhouses and ANOVA to test differences in agrarian land variation among urban areas. Results showed an average of 97.85 ha of abandoned horticultural land and greenhouses providing potential urban cultivable land per city; a one-hectare decrease in non-irrigated land was associated with an 87.98% increase in the odds of potential urban agriculture, and a one-hectare increase in grassland-shrubland was associated with a 67.59% increase in the likelihood of potential urban agriculture.

A case study of Prato Province (Tuscany, Italy) analyzing how urban and peri-urban farming is embedded in local community life. Methods combined spatial analysis, semi-structured interviews with local stakeholders (N=9), field observations and discussions with local farmers (N=17). The study identified a diversity of locally rooted agrifood initiatives and food networks connecting individual farmers with local residents, with farms varying in how re-embedded they were in the urban space of Prato and its inhabitants. Cooperation among local agrifood initiatives was found to contribute to a more sustainable territorial agrifood system, and a tendency toward more sustainable land management was observed in the region. The authors argue that coordinated local food governance and innovative territorial planning instruments could contribute to sustainable agrifood systems elsewhere.
