Residential segregation in urban settings goes far beyond income and socio-economic factors and is also evident in questions of environmental justice, participation and power – including how and where NbS are implemented. Delving into Greek cities, this paper raises the question of whether and how engagement with urban NbS differs within cities and among their residents. By applying a survey with an integrated discrete choice experiment (N = 1002) we were able to analyze the relevance of the type of green area, the effectiveness in temperature and microdust reduction, biodiversity enhancement, time and financial payments and the importance of participatory planning processes. The latent class analysis showed that urban segregation is recognizable within the sample. By investigating the differences in ability and willingness to support urban NbS, this paper recommends how green infrastructure can be implemented in a manner which enforces a more just distribution for those who need it most.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"106 ","pages":"Article 128731"},"PeriodicalIF":6.0,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143479816","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Adjusting roadside vegetation has emerged as a crucial strategy to ameliorate the thermal conditions along roadsides. However, conventional methods are often limited by fixed vegetation types and layout schemes within a limited area, posing challenges in effectively responding to the diverse optimization needs of complex environments. To address this issue, this study proposes a multitype vegetation optimization model based on reinforcement learning. Using street view images, we extracted large-scale, high resolution tree-shrub-grass multitype vegetation. Simultaneously, the optimization and adjustment of the vegetation structure is formulated as a Markov decision process. A pretrained nonlinear model is used to construct a reward mechanism for the cooling effect, and then a reinforcement learning algorithm with the twin delayed deep deterministic policy gradient (TD3) is used for the optimization strategy. Empirical results reveal that in the primary urban area of Beijing, increasing tree density and reducing grass coverage are the most effective strategies for roadside cooling in high-density built-up areas. Conversely, increasing grass coverage is optimal for roadside cooling at urban peripheries. Furthermore, spatially integrated optimization led to a reduction in local land surface temperature (LST) of approximately 1–3 °C, with an average LST reduction of 1.04 °C across the study area. Densely clustered trees contribute to localized cooling effects, whereas dispersed grasses are more effective at promoting overall cooling. These findings offer valuable insights for the formulation of effective urban vegetation planning and management strategies aimed at enhancing the roadside thermal environment.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"106 ","pages":"Article 128729"},"PeriodicalIF":6.0,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143474216","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}

Commensurately, eradication attempts of newly detected exotic pests are burgeoning, with many occurring in urban landscapes where pests are often first detected. While early detection of invading pests is critical to the success of an eradication program, there is a growing need to obtain social licence to operate during a biosecurity response, especially in urban landscapes where multiple stakeholders can hold divergent values on urban trees. Biosecurity measures to eradicate an exotic pest (e.g., tree removal or pesticide/biopesticide application) are often contentious in urban areas and have been identified as a limiting factor in eradication success. Gauging and gaining social licence for control measures in a biosecurity response is needed in advance of the next pest arrival. This review identifies key elements for attaining social acceptability of biosecurity measures before and during a biosecurity response in urban landscapes to assist community and biosecurity agencies prepare for the next exotic pest incursion. Several actions can be taken. Relevant stakeholders can be identified now, their expectations and knowledge base understood, and relationships formed to gain trust and participation in future responses. Understanding public acceptance of biosecurity measures will help gain and maintain social licence in different contexts and develop appropriate communication and engagement approaches. Raising stakeholders’ awareness of the risks and costs of biosecurity incursions and the value of eradication measures can be enhanced when using participatory or co-design approaches and subsequently increase social acceptability of response operations. Reviewing social alongside technical aspects of eradication programs can shed light on ways to improve future programs as well as programs in-progress to support operational success.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"106 ","pages":"Article 128722"},"PeriodicalIF":6.0,"publicationDate":"2025-02-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143487555","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"环境科学与生态学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Proactive assessment of the landscape visual quality (LVQ) before construction ensures proper alignment with future expectations and reduces resource wastage. In this study, we aimed to use virtual reality (VR) and the multidimensional visual indicators, eye-tracking, image segmentation, and spatial features, to assess the human perception of the LVQ of UGSs. This study encompassed three diverse UGS types across northern, central, and southern China, rendering 30 panoramic images for assessment. Sixty participants assessed these images across seven dimensions: beauty, comfort, color, complexity, liveliness, greenness, and safety. Integrating these multidimensional visual indicators, a generalized estimating equations (GEE) logistic regression model demonstrated superior performance over existing traditional models focusing only on spatial features, facilitating more accurate evaluations of LVQ perception. Moreover, herb plants (eye-tracking indicator), water ratio (image segmentation indicator), and number of materials (spatial feature indicator) were the most positive factors affecting human perception. Isolated planting style positively impacted the perception of greenness, and sky ratio negatively correlated with beauty perception. Additionally, openness levels of 20–80 % enhanced beauty perception, while openness above 80 % decreased liveliness but improved safety perceptions. Shrub species diversity positively correlated with perceptions of greenness and complexity, whereas single and dense shrub arrangements diminish perceptions of greenness and liveliness. Overall, this study provides valuable insights for urban planning at the design stage to enhance decision-making and visual quality of UGSs, thereby contributing to the establishment of more sustainable urban development strategies.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"106 ","pages":"Article 128727"},"PeriodicalIF":6.0,"publicationDate":"2025-02-18","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143487546","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}

We found that the soil fungal community in the two sites responded similarly and was broadly resistant to the management applications. However, herbicide application was associated with a reduction in relative abundances of some phyla and families, as well as key functional groups, compared to non-treated controls. Fire appeared to offset the negative effects of herbicide application, indicating complex interactions with the soil fungal community. Herbicide application in combination with fire is critical for grassy weed management and promoting native plant species regeneration in this system.

However, current research tends to visualize street greenery from a single perspective, such as images or planar analysis and neglects pedestrian-scale street tree visual analytics. Space syntax relies on precise urban context data input, and street view image analysis does not cover sidewalk greenery visibility. This study integrates green visibility analysis based on space syntax's Visibility Graph Analysis (VGA) with the Pedestrian Green View Index (PGVI) calculated from street imagery to propose a comprehensive evaluation model for pedestrian-scale green visibility. To validate the accuracy of the methods, we established a participation scoring system involving 183 volunteers to collect their green perceptions of nine types of streets in the City of London, UK. The study reveals a complex relationship between VGA and PGVI, with VGA providing a robust, geometric-based visibility measure and PGVI offering a qualitative, human-centric perspective on urban greenery. Our findings indicate a significant correlation between PGVI and human evaluations, affirming PGVI's potential to reflect pedestrian experiences, while highlighting the limitations of VGA in capturing the nuanced, multi-dimensional aspects of human perception. This underscores the necessity of integrating human feedback in urban planning tools to ensure a comprehensive understanding of green spaces.

Additionally, the Generalized Additive Model (GAM) was employed to explore non-linear relationships between key urban features and LST, offering a deeper understanding of how specific features influence urban temperatures. The results highlight the important cooling effects of ecological attributes like tree height and evapotranspiration, particularly in warm regions (e.g., the Iberian Peninsula and Turkey). Conversely, urban structure elements like built-up volume were shown to increase LST. GAM analysis further revealed non-linear relationships, such as the diminishing returns of evapotranspiration (ET) on cooling in the Iberian Peninsula, where LST decreased sharply at ET &lt; 3–4.5 mm/d but plateaued at higher values. These results emphasize the complexity of urban climate regulation, where ecological and built environments interact in diverse ways across different regions.
