The long-term drivers of inequalities in personal exposure to UGS and the underlying mechanisms remain insufficiently understood. This study measures trends in inequality in UGS exposure in 710 Japanese municipalities over a 20-year period (2000–2020). The direct and indirect effects of economic status, urbanization, and infrastructure investments on inequalities in UGS exposure were analyzed using partial least squares structural equation modeling while considering the mediating roles of land use, demographic, and greening factors. This study found that the distributional inequality in UGS exposure in Japanese municipalities has increased significantly over the past two decades. Economic levels, urbanization, and infrastructure investments drive UGS exposure inequality directly and indirectly through greening and population density. While these relationships may vary by period and region, UGS and population density remain key predictors. Given Japan's challenges related to population decline and aging, cities need to focus on population dynamics and the distribution and size of UGS based on specific economic conditions and stages of urbanization to formulate effective strategies for sustainable development.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"104 ","pages":"Article 128649"},"PeriodicalIF":6.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142888935","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}

This research focuses on balancing water and energy resource conservation with increasing carbon sequestration. We introduced an integrated water–energy–carbon (WEC) fluxes framework to evaluate the net carbon sequestration of green spaces and a water–energy–carbon sustainability index (WECSI) was developed to assess overall sustainability, emphasizing the carbon sequestration potential (CSP). Taking five types of urban green spaces at Zhejiang Agriculture and Forestry University as a case study, we observed significant differences in the WEC fluxes among the green space types. Specifically, mainly arbors and closed green space (AC) types had greater CSP due to scale effects, whereas mainly successional short grass and open green space (SGO) types were at risk of becoming net carbon sources. The WECSI analysis revealed the difficulties in simultaneously achieving water conservation, energy efficiency, and net carbon sequestration, with an average sustainability score of 0.57. To maximize CSP in urban green spaces, scenario analysis indicated that low-carbon irrigation practices could increase CSP by up to 25 %, whereas biomass energy from garden waste could reduce irrigation-related carbon emissions by 19 %. These findings provide a strong foundation for optimizing urban green space management to maximize CSP through WEC fluxes regulation.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"104 ","pages":"Article 128652"},"PeriodicalIF":6.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142918034","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}

To better manage urban forests, it is crucial to assess their ecosystem services. This systematic review analyzes two established urban forest assessment approaches—i-Tree Eco and remote sensing—which have developed independently but hold significant potential for integration. The review, comprising the years 2008 to 2022, evaluates the current status of both methods in assessing urban forest structure and ecosystem services, highlighting opportunities for synergy. The literature shows that while both approaches primarily focus on regulatory services, remote sensing offers more versatile tools for assessing a broader range of ecosystem services beyond i-Tree's standardized scope. Remote sensing holds potential to enhance i-Tree Eco by providing structural and location-specific data at scale, albeit with varying accuracies. Studies have shown that LiDAR data reliably derives tree height and crown width, and that, in combination with multispectral and hyperspectral imagery, it enhances species identification. Additionally, mobile, and terrestrial laser scanners accurately estimate diameter at breast height. However, gaps remain in using remote sensing to assess crown characteristics like crown missing and dieback, which, though not critical, are useful for enhancing ecosystem service estimates in i-Tree Eco. Despite the potential of remote sensing to automate urban tree inventories, limited research has shown its successful integration with i-Tree Eco. Future research should standardize remote sensing techniques for assessing tree crown health. Additionally, further work is needed on quantifying differences between remote sensing and groundbased measurements, with the aim of evaluating uncertainty levels and understanding how these uncertainties impact the reliability and usefulness of data for policymaking and planning.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"104 ","pages":"Article 128659"},"PeriodicalIF":6.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142939691","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}

Urban green and blue infrastructure (UGBI), including green spaces and water bodies, plays a key role in mitigating the urban heat island effect and promoting urban resilience. This study analyzed 4617 urban green spaces (UGS) across twelve U.S. cities, representing a range of Köppen climate zones, to explore the structural and functional attributes that contribute to urban cooling. Using GIS and Generalized Linear Mixed Models (GLMM), we examined the interactions between UGS and blue spaces to better understand their combined effect on local temperature regulation. Our findings underscore the importance of vegetation density, proximity to water, and park size in reducing land surface temperature (LST), with average LST reductions of up to 3 °C in parks with denser vegetation. Greener parks, located near water bodies, were strongly associated with cooler temperatures, emphasizing the synergistic cooling effect of UGBI. Larger parks, particularly those around 350 ha, were more effective at reducing LST. Interestingly, taller buildings adjacent to UGS showed a slight increase in LST until a height of approximately 20 m, after which the effect plateaued. Proximity to water showed a strong cooling effect within 4 kilometers, beyond which the effect diminished and eventually reversed. These findings provide actionable insights for urban planners and policymakers, illustrating how strategic UGBI interventions—especially in cities with high-density urban forms—could reduce local temperatures, mitigate heat-related risks, and enhance urban resilience to climate change.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"104 ","pages":"Article 128660"},"PeriodicalIF":6.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142939692","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}

Understanding the makeup of the street tree community, and therefore the extent of those services, requires a consideration of past policies that contributed to the patterns we see today. Inequities in environmental conditions in US cities, including access to street trees, has been shown to be a product of race-based federal policies such as the Federal Home Owners’ Loan Corporation (HOLC), which graded communities in the 1930’s according to perceived levels of risk for mortgage lending. We used a 2021 tree inventory to examine whether a legacy of HOLC designations is still observable in the modern urban forest of Schenectady, NY (USA) by comparing the size, number, and diversity of trees within various HOLC grades. The lower-graded areas, C and D, had about half the number of trees as the higher-rated A- and B-graded areas. The trees in D-graded areas were also smaller and were the least taxonomically diverse. In recent years, however, tree plantings have disproportionately favored D-graded areas over A- and B-graded areas. Despite the progress, this study adds to the growing literature that the underprivileged neighborhoods, historically made up of people of color, are not receiving equivalent environmental benefits as wealthier areas. Identifying such patterns highlights the obligation to construct public policy approaches that target the inequities in urban forest conditions so that all residents benefit equally from the services that trees in urban environments provide.</div></div>","PeriodicalId":49394,"journal":{"name":"Urban Forestry & Urban Greening","volume":"104 ","pages":"Article 128679"},"PeriodicalIF":6.0,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143157905","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, we use a gridded implementation of the rational method, with flow attenuation included (ANaRM model), to assess the reduction in runoff that can be achieved by implementing urban land-use change to achieve 3–30–300 targets in three European cities of contrasting size and population: Aarhus Municipality (Denmark), Grad Velika Gorica (Croatia) and Paris Region (France). We find that the creation of new green spaces and tree cover can greatly reduce peak pluvial surface runoff rate at-site, and maintain peak flow reductions of several percent in sub-catchments of several square kilometres, including reductions of over 10 % in some sub-catchments of over 20 km² in Paris.

However, thorough investigations into how the three-dimensional (3D) structures of urban forests influences urban thermal conditions collectively and individually are limited. In this study, voxel-based landscape indices were innovatively extracted from UAV LiDAR data, and high-precision land surface temperature (LST) data were obtained using thermal infrared sensors mounted on a UAV. These were combined with a random forest (RF) model to analyze the relative influences and marginal effects of urban forest three-dimensional (3D) structure on LST. Our results showed the following: (1) The voxel-based landscape index exhibits a stronger capability to interpret LST than both the 2D landscape index and the gradient-based landscape index, with significant enhancements in model accuracy across all dimensions (an increase in R of 0.17–0.25 and a decrease in RMSE by 0.39–1.59°C). (2) Considering the vertical stratification of tree canopies, which voxel-based landscape index has the greatest LST fitting precision (R = 0.75, RMSE = 3.11°C). Including the canopy's vertical layers in analyses is pivotal, with the upper canopy layers exerting the most significant influence on reducing LSTs. (3) The scale of the grid impacts the accuracy of LST fitting, showing a trend where accuracy increases and then decreases with increasing grid scale; at the 40-m scale, the landscape indices demonstrate their highest explanatory capacity for LST (2D landscape index R=0.43, RMSE=4.65°C; gradient-based landscape index R=0.56, RMSE=4.07°C; voxel-based landscape index R=0.68, RMSE=3.94°C; vertical stratification (VS) voxel-based landscape index R= 0.75, RMSE= 3.30°C.). (4) Volume, proportion of volume, surface area, and diversity represent the parameters that most significantly influence variations in LST. Notably, volume, proportion of volume, and surface area exhibit a significant negative correlation with temperature, whereas diversity displays a distinct positive correlation. For the whole canopy at the optimal scale of 40 m, a volume within 4200 m3, proportion of volume within 0.8, and a surface area within 18000 m2 are associated with a cooling effect. For the upper canopy, volume within 1200 m3, proportion of volume within 0.22, and surface area within 2000 m2 are associated with a cooling effect. This study unequivocally confirms the feasibility of using drones with LiDAR and thermal infrared sensors to analyze small-scale UHI issues. This approach is beneficial for describing the 3D structure of a forest and fitting surface temperature.

This study focuses on Shanghai to investigate cooling service exposure and equity patterns. Using the Heat Mitigation Index (HMI) from the newly LAI-integrated InVEST urban cooling model as a proxy for vegetation cooling services, as well as the Gini index as the indicator of equity, we analyzed cooling exposure and equity across the urban-rural gradient and among different population groups at multiple levels. The results indicate that: 1) Integrating Leaf Area Index (LAI) improves HMI simulation accuracy by enhancing heterogeneity within green areas and strengthening the correlation with land surface temperature (LST) by up to 67.5 %. 2) Cooling service exposure and inequity display a clear urban-rural gradient, with residents in central areas enjoying lower but more equitable cooling services, while those in peripheral areas experiencing higher but less equitable services. Specifically, the average cooling exposure, measured on a normalized range from 0 to 1, increases from 0.130 in the Inner Urban Area (IUA) to 0.211 in the Outer Suburban Area (OSA), and the Gini index rises from 0.298 to 0.486 from the inner to the outer ring, indicating greater inequality in peripheral. 3) Gaps in cooling service exposure and equity among population groups, based on age and local status, are widening along the urban-rural gradient.

In tandem with an increasing recognition of the importance of urban forests for addressing various challenges facing human societies and ensuring sustainable development, UFUG has attracted more and more scholarly attention. Over the past two decades (2002–2023), scholars from all over the world have produced a wide variety of scholarship, totaling up to 90 volumes with 2655 articles published from multiple fields, which has significantly improved our understanding of urban forests as integral parts of urban social-ecological systems.
