This study employed CiteSpace™ software to conduct a comprehensive bibliometric analysis of NbS and UF-NbS in literature, utilising the Web of Science (WoS) databases for literature in English. 2014 – 2021 emerges as a period during which foundational theories, early applications, and key trends emerged in NbS research which have shaped the field. Visualisations of NbS applications, particularly in urban forest management are presented along with an analysis aimed to uncover research patterns and collaborative pathways. In addition, the paper sets out to establish the groundwork for further investigations into urban forest disciplines based on NbS science and key technological innovations. The primary findings are that research on NbS and UF-NbS has emerged as a hot topic in recent years; that European institutions and groups have played an essential role in the development of this field by fostering close academic cooperation networks, and that research elsewhere, such as China, is still in its development stage. We propose that future studies should add other web directories, search in other languages and utilise multiple bibliometric tools. It is evident that research in this domain continues to evolve rapidly and that bibliometric studies from 2022 onwards can help identify emerging research directions and applications.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"112 ","pages":"Article 128955"},"PeriodicalIF":6.0,"publicationDate":"2025-07-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144621946","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, seven green façades in Berlin, Germany greened with five plant species were harvested and their annual biomass production rates were measured separating herbaceous, wooden, and fruit biomass. The bioenergetic potentials of the biomass were analyzed for conversion by combustion and via biogas. The annual biomass production rates for the wall area, ground area, and the urban quarter were estimated. <em>H.

The biomass showed higher heating values of 16.2–19.8 MJ kg⁻¹ and methanogenic potentials of 126–238 L_N kg⁻¹. Combustion and methane production resulted in 1.6–18.3 MJ m⁻² a⁻¹ and 0.5–6.2 MJ m⁻² a⁻¹ per façade area, respectively. Green façades produce significantly more biomass per ground area than agricultural and silvicultural systems. This underscores the importance of green façades in promoting sustainable and ethical urban biomass and bioenergy production, while adding value to unused vertical surfaces without intensifying land-use competition.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"112 ","pages":"Article 128951"},"PeriodicalIF":6.0,"publicationDate":"2025-07-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144596632","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Spatially, urban vegetation productivity is prevalently higher than that in nearby rural backgrounds (+31.77 % ± 49.55 %), with greater enhancement ratio in highly urbanized blocks.

Notable differences in the local changes of vegetation productivity were observed within cities, as new urban areas had greater increasing trends than old urban areas. The local changes in urban vegetation productivity are primarily determined by the intensity of urbanization and its changes, further modulated by city’s climatic and socioeconomic conditions.

However, several individual and institutional barriers, including social acceptability, can hinder the successful implementation of these initiatives. This study aims to understand the decision-making processes and citizen perceptions associated with urban greening and depaving initiatives in Quebec City. Using a mixed-methods approach, we conducted detailed interviews with 18 stakeholders and a questionnaire-based survey of 770 residents in the city. Our findings show that these initiatives could be characterized into five project types, comprising community-supported projects and projects led by different city departments, including engineering, urban planning, and mobility, with smaller contributions from departments such as recreation park services. While a horizontal structure between these departments fostered collaboration, a top-down approach to the decision-making process limited the implementation of such initiatives. In addition, economic, technical, and organizational barriers were limiting factors, particularly the perceived lack of citizen support for these initiatives. Nevertheless, the survey results revealed strong support from citizens, with more than 80 % of participants expressing moderate to high levels of support. In addition, while nearly half of the survey participants (47 %) identified private car use as their preferred mode of transport, the participants showed a willingness to reduce parking spaces to support depaving initiatives. To overcome the barriers to and promote the successful implementation of urban greening and depaving initiatives, greater collaboration between decisionmakers, professionals, and the community in Quebec City is needed. Our results have significant implications for advancing such initiatives beyond Quebec City. By examining stakeholders’ perceptions, our findings can inform decision-making processes and promote the adoption of public policies to support these initiatives in city planning agendas.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"112 ","pages":"Article 128947"},"PeriodicalIF":6.0,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144563504","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Analysing remote sensing and citizen science data from Brisbane, Australia, we find that bird species richness within urban greenspaces has a strong positive association with vegetation complexity, but no significant association with tree cover or water cover. These results suggest that urban greenspace management strategies that focus simply on increasing tree cover might overlook valuable biodiversity enhancement opportunities. We also explore how these three management goals influence the presence of individual species and find that the effect of each variable varies among species. These results highlight the importance of formulating urban greenspace management plans with specific objectives in mind—a particular management approach will benefit some species, but harm others.

Therefore, efforts to adapt and repurpose current infrastructure to house essential green space must be made. Green roofs offer a sustainable, nondestructive solution that can help to address climate-related issues in urbanised areas, such as poor air quality, lack of green space, and the urban heat island effect. Previous studies have highlighted the potential of green roofs in an urbanised environment with regard to these benefits, however, further scope remains to identify the combination of vegetation that present optimal efficiency for carbon sequestration in a temperate climate. This study focuses on improving the University of Bristol’s initial attempt of green roof implementation and provides a guideline for further expansion with emphasis on maximising carbon capture. Initially, a diverse range of plant samples were considered. Then, the appropriate plant species were analysed comparatively in laboratory testing to differentiate their rates of photosynthesis and the total carbon content in mature plants. The plants’ macroscopic build-up and lifecycle was considered along with the laboratory results to create a theoretical optimum green roof arrangement for carbon capture. Finally, a computer model was developed using structural data from the university’s city campus to analyse the net predicted carbon sequestration when appropriate infrastructure was converted to the optimal green roofs. This research aimed to reveal which plant species are most suitable for the application to green roofs with regards to carbon capture and henceforth improve existing green infrastructure on the university’s campus. The model’s objective was to showcase the significance of the results in a relevant, real-world application and exhibit the achievable net decrease in carbon emissions to the atmosphere by the University of Bristol. A system of green roofs composed of <em>Lavandula</em> is predicted to capture 4.12kgCO2/m2year, which is the optimal outcome of this research and contrasts with <em>S. Spurium</em>, a common planting on green roofs which is only forecast to capture 0.14kgCO2/m2year. This substantiates the argument that the choice of vegetation plays a crucial role in the performance of the carbon sink active in a green roof. The findings of this study can be replicated for other urban sites and their vegetation choices for their green roofs.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"112 ","pages":"Article 128946"},"PeriodicalIF":6.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144566073","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to a lack of long term field-based studies, the dynamic characteristics of C storage and sequestration by urban greenery over multiple years remain poorly understood. Here we developed specific allometric equations for various types of urban vegetation, and quantified the C storage and sequestration of urban greenery with different compositions of vegetation and landscape types across Beijing, from 2010 to 2020. This was based on field measurements from 604 sampling plots, combined with a dataset derived from the Urban Landscape Architecture Survey of Beijing. Our results showed that the biomass of urban vegetation (including various tree, shrub and bamboo species) could be well predicted using a combination of dendrometric variables, such as diameter at breast height (DBH), diameter at ground level (G), canopy width (W) or the height (H) of plants. Total (above- and below-ground) C storage by urban greenery increased from 2.6 Tg C (1 Tg = 10¹² g) in 2010–6.3 Tg C in 2020, with the C sequestration of 0.32–0.43 Tg C yr⁻¹. The C density of urban greenery varied from 4.1 to 6.9 kg C m⁻² between 2010 and 2020, representing an annual C sequestration rate of 0.20–0.34 kg C m⁻² yr⁻¹. Combining this with a similar estimate for Beijing’s urban greenery in 2005 revealed that between 2005 and 2020, the C storage and density of urban greenery increased linearly over time. However, the C sequestration or annual C sequestration rate initially increased and then diminished over 2005–2020, which is likely linked to changes in vegetation physiology and plant age structure. These findings emphasize the need for effective management, such as planting optimal native vegetation types and species to maximize local adaptation and C uptake, as well as the expansion of urban vegetation, to enhance C storage and sequestration, thereby offering valuable insights for leveraging urban greenery strategies to mitigate climate change.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"112 ","pages":"Article 128944"},"PeriodicalIF":6.0,"publicationDate":"2025-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144566076","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
