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.

An overview and guidance for air pollution indicators in nature-based solutions (NBS) for urban green planning and public health were provided, using three case studies in Europe and Latin America. The study noted that approaches including multidimensional indicators in research, planning, and policies are limited, and national standards for some air pollutants are missing with little evidence for health effect thresholds. Findings also indicated that knowledge of pollutant uptake in edible plants can suggest potential human exposure risks.

The cooling potential of allotments across European Functional Urban Areas (FUAs) was assessed. Allotments provide cooling services to 4.1 million people within FUAs, including 1.7 million in Germany. Each square kilometer of allotments cools an average of 8,221 people, with the cooled area being, on average, 2.8 times larger than the allotment size. Urban agriculture was 23% more efficient than peri-urban agriculture, but only 5% of allotments cooled areas with the highest heat risk.

Grassl, Philipp · reposiTUm (TU Wien) · Europe

The diploma thesis "hydro ponos" at the Vienna University of Technology addresses a new type of agriculture in Vienna's urban context. The project proposes a hydroponic system in a vertical farm, choosing the vacant Flakturm (anti-aircraft tower) in Augarten as the construction site. The study suggests a solution for the city by utilizing the existing Flakturm as a storage and supply element and adding a new timber skeleton structure as an extension.

This study aimed to identify and evaluate the urban agriculture potential in Edirne, Turkey, based on the hypothesis of transforming passive areas into urban agricultural areas. It conducted a literature review, reported on climate, topography, vegetation cover, and land use conditions, and used SWOT analysis to evaluate potential in technological, economic, demographic, sociological, and ecological contexts. The study determined that urban agriculture practices in Edirne, where the existing structure is quite favorable, can be evaluated as a strategic development tool with proper planning and management.

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.

This article analyzes how biophilic architecture employs immersive strategies to transform buildings into environments that support sensory, behavioral, and social practices. It analyzes projects such as the Rooftop Garden—Warsaw University Library, Musée du quai Branly, and apartment buildings Bosco Verticale, and proposes a Multi-criteria Method for Assessing Architectural Immersiveness (MMAAI). Findings indicate that the integration of nature, technology, and spatial narrative enables architecture to act as a mediator between humans and the environment, generating new qualities of spatial experience in the Anthropocene epoch.

This study used the Pseudo Global Warming method and WRF model to assess urban heat adaptation strategies in the Metropolitan Area of Barcelona. Three strategies were evaluated: increasing rooftop albedo, implementing irrigated sedum green roofs, and increasing peri-urban agriculture and urban parks. While increasing rooftop albedo provided the greatest daytime cooling (−1.75 °C), and green roofs and peri-urban agriculture showed moderate regulation, none of the strategies fully counterbalanced the projected 6 °C temperature increase by 2100, indicating a limited capacity of these adaptations under severe warming scenarios.

This study presents a methodology for estimating potential biomass and carbon accumulation over a 40-year timespan for European afforestation activities, developed for the Life Terra project (LIFE19 CCM/NL/001200). It synthesized data from allometric equations, yield tables, national forest inventories, and national greenhouse gas inventory reports across four European biogeographic regions — Alpine, Atlantic, Continental, and Mediterranean — with the analysis focused mainly on timber plantations due to data availability and reliability constraints. Initial planting densities varied substantially across regions (1,869-7,702 trees/ha) and declined exponentially over time; by year 40, individual tree biomass estimates ranged from 0.08 to 0.20 t/tree with survival rates of 22.0-49.7%, giving stand-level biomass estimates of 54.7-232.6 t/ha. The estimates generally aligned with country-specific literature and IPCC default values but showed considerable site-to-site variation, and the study notes remaining uncertainties related to survival/mortality rates and climate change impacts.

A study of six experimental case studies in the metropolitan city of Bologna, Italy, describing urban community gardens (UCGs) as examples of co-production in Nature-Based Solutions (NBS), focused on the design and development of circular strategies for water reuse. It situates Bologna as a context where urban horticulture has long served as local welfare and is now evolving to host solutions supporting environmental resilience, and reports the implementation of social innovation pathways, community building and citizen engagement enabled through co-design activities using open innovation approaches, particularly Urban Living Labs (ULLs), which facilitated the development and testing of locally adapted, do-it-yourself solutions. The analysis concludes that the implemented solutions had significant social and economic impact, demonstrating UCGs' effectiveness as NBS in strengthening communities, contributing to the 2030 Agenda SDGs, and validating the outcomes of the participatory co-production approach.

In Vojvodina Province, northern Serbia — a rural region where 70% of the territory has been converted to arable land — researchers used QGIS to map areas suitable for implementing Nature-based Solutions (NbS), drawing on CORINE Land Cover, OpenStreetMap, data from the Institute for Nature Conservation of Vojvodina Province, and the EUNIS platform. The area suitable for NbS totaled 1,183,228 ha, or 55.74% of the province, with organic and regenerative agriculture projected to increase by up to 5%. Grazing was identified and mapped as a desirable grassland management option, potentially practicable on nearly 10% of the territory.

Yu Huan, Steffen Nijhuis, Nico Tillie · Journal of Cleaner Production · Europe

Using Rotterdam as a case study, researchers combined machine-learning suitability modeling (XGBoost with SHAP), deep-learning land-use simulation, and monetary ecosystem-service valuation to compare three scenarios for 2030 and 2050: business-as-usual, suitability-based autonomous transformation, and a suitability-based landscape-approach transformation. Suitability-guided scenarios outperformed business-as-usual, with the landscape-approach scenario producing the most stable multi-decadal outcomes for regulating and cultural services, but provisioning services could plateau or decline when ecological protection constraints limited intensive production.
