Air pollution events pose significant challenges to public health in Melbourne and Sydney, Australia’s most populous cities. This study evaluates publicly available data to understand the frequency of air pollution exceedance events beyond World Health Organization (WHO) guidelines, as well as national and state standards. The air quality of both cities generally complies with national standards but consistently fails to meet WHO air quality guidelines. Since 2000, Sydney recorded single-pollutant events on 43% of monitored days and multi-pollutant events on 14% of monitored days. In Melbourne, single-pollutant events were recorded on 42% of monitored days, and multi-pollutant events on 8%. In Sydney, NO₂ exceeded WHO guidelines on 52% of monitored days, PM_2.5 on 13%, PM₁₀ on 4%, and O₃ on 6%. In Melbourne, NO₂ exceeded on 47% of monitored days, PM_2.5 on 4%, PM₁₀ on 6%, and O₃ on 2%. Evaluating long-term, city-scale air quality is challenging due to significant variations in spatial and temporal data coverage, especially in Melbourne. Many monitoring stations have limited temporal coverage and do not consistently monitor all key pollutants, meaning the true extent of air pollution is likely not fully captured. Since 2017, Melbourne has had only five active monitoring stations, compared to over 15 in Sydney. This study demonstrates the urgent need for expanded air pollution monitoring networks in Australia’s largest cities and highlights the need for ongoing research into the impacts of multi- as well as single-pollutant exceedance events.

在澳大利亚人口最多的城市墨尔本和悉尼，空气污染事件对公众健康构成了重大挑战。本研究评估了公开可用的数据，以了解超出世界卫生组织（WHO）准则以及国家和州标准的空气污染超标事件的频率。这两个城市的空气质量总体上符合国家标准，但始终未能达到世卫组织的空气质量准则。自2000年以来，悉尼记录的单一污染物事件占监测天数的43%，多污染物事件占监测天数的14%。在墨尔本，42%的监测天数记录了单一污染物事件，8%的监测天数记录了多重污染物事件。在悉尼，有52%的监测天数二氧化氮超标，PM2.5超标13%，PM10超标4%，O3超标6%。在墨尔本，二氧化氮超标天数占监测天数的47%，PM2.5超标天数占4%，PM10超标天数占6%，臭氧超标天数占2%。由于空间和时间数据覆盖范围的显着变化，特别是在墨尔本，评估长期城市尺度的空气质量具有挑战性。许多监测站的时间覆盖范围有限，并没有持续监测所有主要污染物，这意味着可能无法完全捕捉到空气污染的真实程度。自2017年以来，墨尔本只有5个活跃监测站，而悉尼有超过15个。这项研究表明，迫切需要在澳大利亚最大的城市扩大空气污染监测网络，并强调需要对多种和单一污染物超标事件的影响进行持续研究。

Air pollution caused by NO

emissions related to traffic is a major environmental issue in the Brussels-Capital region. Using a large set of measurements collected from a citizen science campaign, this paper shows how such data help us to get an overview of the spatial distribution of NO

levels over the region. Using two land use regression techniques, these levels were related to spatial proxies collected at the measurement locations. Comparing the proxies selected by each regression method offers deeper insights into the NO

-proxies relationships and helps identify proxies that may have been overlooked in a simpler multilinear regression model. Results show that the multiple linear regression model is able to explain a major part of the variance of the data, while random forest regression performs slightly better, with performances that are on par with those found in the literature. However, both models tend to underestimate high concentrations that are occurring locally. Thanks to a comparison with the prediction results from a physics-based model, this could be related to the quality of the input traffic data, that are expected to play a major role as most of nitrogen oxides emissions in the Brussels-Capital region originate from road traffic.

与交通有关的二氧化氮排放造成的空气污染是布鲁塞尔首都地区的一个主要环境问题。本文利用从公民科学运动中收集的大量测量数据，展示了这些数据如何帮助我们对该地区二氧化氮水平的空间分布进行概述。利用两种土地利用回归技术，这些水平与在测量地点收集的空间代用指标相关。比较每种回归方法选择的代理可以更深入地了解no2 -代理关系，并有助于识别在更简单的多元线性回归模型中可能被忽略的代理。结果表明，多元线性回归模型能够解释数据的大部分方差，而随机森林回归的表现略好，其性能与文献中的表现相当。然而，这两种模式都倾向于低估局部发生的高浓度。通过与基于物理的模型的预测结果进行比较，这可能与输入交通数据的质量有关，由于布鲁塞尔-首都地区的大部分氮氧化物排放来自道路交通，预计交通数据将发挥主要作用。

Green spaces (GS) promote positive people–place relationships, especially in residential areas. Availability of GS in Middle Eastern cities has been influenced by their unique political, socio-economic, cultural and environmental conditions. Despite this, research on GS availability in relation to city development context is still limited. This study examines the patterns of GS availability in Damascus’s residential areas and analyses its correlation with these areas’ development context. It classifies districts by urbanisation context and GS metrics, using content analysis, secondary data and NDVI analysis. Results showed that GS availability in Damascus is significantly influenced by urban history, geography and political-economic systems, underscoring current urban challenges faced by other major Middle Eastern cities. In Damascus, district groups were highly influenced by their historical background from the pre-mid-20th century and the political-economic system that developed later. The study revealed significant disparities between planned northern and western districts with better GS availability, and informal eastern and southern ones. These findings highlight the need for context-sensitive, multidisciplinary strategies to address GS disparities in Middle Eastern urban residential areas, including governance tools such as local GS councils and equity audits, to promote equitable access and strengthen people–place relationships.

绿色空间（GS）促进积极的人与地关系，特别是在住宅区。中东城市的GS供应受到其独特的政治、社会经济、文化和环境条件的影响。尽管如此，关于城市发展背景下GS可用性的研究仍然有限。本研究考察了大马士革居民区的GS可用性模式，并分析了其与这些地区发展背景的相关性。它使用内容分析、二手数据和NDVI分析，根据城市化背景和GS指标对地区进行分类。结果表明，大马士革的GS可用性受到城市历史、地理和政治经济制度的显著影响，这凸显了其他中东主要城市当前面临的城市挑战。在大马士革，地区团体深受20世纪前中期的历史背景和后来发展起来的政治经济制度的影响。该研究显示，规划好的北部和西部地区具有较好的GS供应，而非正式的东部和南部地区则存在显著差异。这些研究结果突出表明，需要采取对具体情况敏感的多学科战略来解决中东城市住宅区的人口普查差距问题，包括地方人口普查委员会和公平审计等治理工具，以促进公平获取和加强人与地的关系。

The present experimental research focuses on surface water quality adjacent to an urban landfill, Dhaka, Bangladesh, where collected samples were analysed in laboratories by assessing 19 physicochemical parameters, and advanced statistical techniques were performed to establish a Water Quality Index (WQI). Providing valuable insights into the spatial extent and characteristics of surface water pollution, the study intends to support local authorities in identifying high-risk zones for targeted water quality and in developing policies for monitoring waterbodies to ensure sustainable landfill management. Results indicated moderate total dissolved solids (TDS) (about 400 mg/L), low dissolved oxygen (DO) (less than 4 mg/L), and significant pollutant variability. Clustering indicated that the first one consisted of samples collected nearer to the landfill, exhibiting excessive chemical oxygen demand (COD), biochemical oxygen demand (BOD), and total suspended solids (TSS), while the second one contained samples collected farther away from the landfill, demonstrating superior water quality. The WQI categorized three samples as very bad 405 (WQI < 31) and seven as bad (WQI between 31 and 51.9), with the lowest value recorded as a WQI of 1.85 from a sewer. Principal component analysis (PCA) identified five principal components (PCs), with PC1, PC2, and PC3 accounting for 38.5 %, 21.38 %, and 16.35 of the total variance, respectively. These findings indicate the necessity for immediate measures: the establishment of engineered landfills, leachate treatment, and the enforcement of more stringent waste restrictions to mitigate health and environmental hazards around the urban landfill. The study’s scientific significance resides in its provision of a comprehensive WQI and specific pollution data, thereby augmenting the understanding of urban landfill effects on water quality in densely populated areas. The study has the potential to guide the development of policies for sustainable waste management, presenting a framework for reducing urban surface water pollution.

目前的实验研究侧重于孟加拉国达卡城市垃圾填埋场附近的地表水质量，在实验室中通过评估19个物理化学参数对收集的样本进行分析，并使用先进的统计技术来建立水质指数（WQI）。该研究为地表水污染的空间范围和特征提供了有价值的见解，旨在支持地方当局确定目标水质的高风险区域，并制定监测水体的政策，以确保可持续的垃圾填埋场管理。结果表明，该地区总溶解固形物（TDS）适中（约400 mg/L），溶解氧（DO）较低（小于4 mg/L），污染物变异性显著。聚类结果表明，第一个样本采集于离垃圾填埋场较近的地方，其化学需氧量（COD）、生化需氧量（BOD）和总悬浮物（TSS）超标；第二个样本采集于离垃圾填埋场较远的地方，其水质较好。WQI将三个样本分类为非常糟糕的405 (WQI <；31)和7（水质指数介于31至51.9之间），其中最低的污水渠的水质指数为1.85。主成分分析（PCA）鉴定出5个主成分（PCs），其中PC1、PC2和PC3分别占总方差的38.5%、21.38%和16.35%。这些发现表明有必要立即采取措施：建立工程垃圾填埋场，进行渗滤液处理，并实施更严格的废物限制，以减轻城市垃圾填埋场周围的健康和环境危害。这项研究的科学意义在于它提供了一个全面的世界水质指数和具体的污染数据，从而增加了对人口稠密地区城市垃圾填埋场对水质影响的认识。这项研究有可能指导可持续废物管理政策的制定，提出减少城市地表水污染的框架。

With the global population now exceeding 8 billion and 4.5 billion of whom residing in urban areas, rapid urbanization has contributed to a range of environmental and ecological challenges, notably the Urban Heat Island (UHI) effect. According to statistical data, the ten hottest years on record occurred between 2013 and 2022, underscoring the urgency of addressing urban heat issues. This study provides a comprehensive review of research on the UHI effect, analysing and classifying studies that utilize a variety of input–output datasets. It also examines predictive methods used to estimate UHI intensity, categorizing them into conventional machine learning (ML) algorithms, deep learning (DL) models, and hybrid approaches. While conventional ML algorithms remain widely used, DL and hybrid models have shown superior performance in predictive accuracy. This review aims to enhance understanding of recent advancements in UHI prediction techniques, identify limitations in current methodologies, and propose directions for future research.

随着全球人口超过80亿，其中45亿人居住在城市地区，快速城市化带来了一系列环境和生态挑战，特别是城市热岛效应。统计数据显示，有记录以来最热的10年发生在2013年至2022年之间，凸显了解决城市高温问题的紧迫性。本研究全面回顾了关于城市热岛效应的研究，对利用各种投入产出数据集的研究进行了分析和分类。它还研究了用于估计UHI强度的预测方法，将它们分为传统的机器学习（ML）算法、深度学习（DL）模型和混合方法。虽然传统的机器学习算法仍然被广泛使用，但深度学习和混合模型在预测准确性方面表现出优异的性能。本综述旨在加强对热岛预测技术最新进展的理解，确定当前方法的局限性，并提出未来研究方向。

Climate change has made heatwaves common during German summers. The phenomenon of urban heat islands (UHIs) only worsens the adverse effects of heatwaves, especially for the elderly, defined as population aged 65+ for this study. These issues need immediate attention and redress to avoid catastrophic consequences. For this research investigation, the city of Darmstadt in Germany has been mapped for heatwaves and UHIs. An assessment has been done to derive interrelationships between them and characteristics of the built environment. Rather than applying a generic Local Climate Zones classification, the built environment has been assessed by clustering the city of Darmstadt based on the UrbanReNet catalogue—a more contextual and nuanced urban typologies-based classification developed specifically for German cities. The findings of this study show that certain urban typologies are more prone to overheating, and can also significantly influence the thermal conditions of their surroundings. The latter is established by a novel multivariate regression that employs the H3 hierarchical geospatial indexing system. Further, mapping of the elderly in Darmstadt revealed that about half of them reside in settings that are at risk of overheating during a heatwave. This study provides a novel methodology to delineate areas at maximum risk of overheating. This can help prioritize heatproofing efforts to minimize the risk of excessive heat stress by focusing on the most vulnerable.

气候变化使得热浪在德国夏季司空见惯。城市热岛（UHIs）现象只会加剧热浪的不利影响，特别是对老年人，本研究定义为65岁以上的人口。这些问题需要立即加以注意和纠正，以避免灾难性后果。在这项研究调查中，德国达姆施塔特市已经绘制了热浪和UHIs地图。已经进行了一项评估，以得出它们与建筑环境特征之间的相互关系。建筑环境的评估不是采用一般的局部气候区分类，而是基于UrbanReNet目录对达姆施塔特市进行聚类，这是一种专门为德国城市开发的基于环境和细致入微的城市类型学的分类。这项研究的结果表明，某些城市类型更容易过热，也可以显著影响其周围的热条件。后者是通过采用H3层次地理空间索引系统的一种新的多元回归建立的。此外，达姆施塔特的老年人地图显示，大约一半的老年人居住在热浪中有过热风险的环境中。这项研究提供了一种新的方法来划定过热风险最大的区域。这可以帮助优先考虑防热工作，通过关注最脆弱的人来最大限度地减少过度热应激的风险。

The urban heat island (UHI), which describes the warmer temperature over urban landscape, is the most studied climate effect of cities. Most studies focus on the surface and canopy layers, particularly in common urban configurations such as street canyons. The causes of the UHI include aspects of physical form, fabric and of functions and, while urban forms are treated as fixed (over short time periods), functions are considered dynamic. In this context, the thermal and radiative properties of street facets like roads are critical urban canopy parameters (UCPs) that are used to understand heat storage and surface-air exchanges. However, the role of vehicles, especially parked ones, in modifying these surface properties and associated UCPs has been largely overlooked. This short contribution examines the impact of parked and mobile vehicles in cities using data from Lisbon, Portugal. Our findings highlight that parked vehicles significantly alter surface thermal properties in densely built areas, where road coverage is extensive and UHI intensity is greatest.

城市热岛（UHI）是研究最多的城市气候效应，它描述了城市景观上温度升高的情况。大多数研究集中在地表和冠层，特别是在常见的城市配置，如街道峡谷。城市热岛的原因包括物理形式、结构和功能方面，虽然城市形式被视为固定的（在短期内），但功能被认为是动态的。在这种情况下，道路等街道表面的热和辐射特性是关键的城市冠层参数（ucp），用于了解热量储存和地表空气交换。然而，车辆，特别是停放的车辆，在改变这些表面特性和相关ucp方面的作用在很大程度上被忽视了。这篇简短的文章使用来自葡萄牙里斯本的数据，研究了城市中停放和移动车辆的影响。我们的研究结果强调，在道路覆盖范围广、热岛强度最大的建筑密集地区，停放的车辆显著改变了地表热性能。这些见解强调了在城市热岛研究中考虑停放车辆的必要性，以及在空间上有针对性的缓解战略的潜力，例如限制在已确定的热点地区停车，建造遮阳结构，以及推广浅色车辆，而不是深色车辆。

Worldwide, flood resilience strategies are increasingly moving from theoretical frameworks to on-the-ground application, especially in regions grappling with climate change and rapid urbanization. North African coastal cities face heightened flood risks driven by intensified rainfall, sea-level rise, and significant land-use transitions. This paper introduces a contextual flood resilience framework − encompassing governance, socio-economic, and environmental dimensions − and applies it to the city of Jijel, Algeria. Integrating GIS-based land-use analyses with stakeholder surveys and policy reviews, the study identifies institutional fragmentation, outdated urban planning, and informal housing as key drivers of vulnerability. Results suggest that strengthening legal and institutional frameworks, investing in adaptive infrastructure, and fostering collaborative governance are critical for long-term flood resilience. In offering targeted recommendations for North African coastal settings, this research underscores the value of a multidimensional, context-sensitive approach to addressing flood risks across a rapidly changing urban landscape.

在世界范围内，抗洪战略正日益从理论框架转向实际应用，特别是在应对气候变化和快速城市化的地区。由于降雨加剧、海平面上升和土地利用的重大转变，北非沿海城市面临着更大的洪水风险。本文介绍了一个包含治理、社会经济和环境维度的背景洪水恢复框架，并将其应用于阿尔及利亚吉耶勒市。该研究将基于gis的土地利用分析与利益相关者调查和政策审查相结合，确定了制度碎片化、过时的城市规划和非正规住房是脆弱性的主要驱动因素。研究结果表明，加强法律和制度框架，投资于适应性基础设施，促进协作治理对长期抗洪能力至关重要。这项研究为北非沿海地区提供了有针对性的建议，强调了在快速变化的城市景观中解决洪水风险的多维、情境敏感方法的价值。

Urban agriculture (UA) is increasingly recognized as a potent strategy for addressing contemporary urban challenges, particularly in the developing world, where rapid urbanization and climate change impacts are rising. However, the role and the extent to which UA has been integrated into national strategic policies and programmes remain underexplored in African cities, especially Accra, Ghana. This paper explores the role of UA in building climate resilience in Accra, Ghana, from the perspective of policymakers. It critically examines the extent to which UA has been integrated into national policy frameworks and identifies the barriers undermining its broader adoption and implementation. We employ a mixed-methods approach, drawing on stakeholder interviews, document analysis, and policy reviews to provide empirical insights while guided by resilience theory and the political ecology framework as analytical lenses. Stakeholder perspectives indicate that UA contributes to resilience through localized food production that supports nutritional security, the use of treated wastewater to enhance water efficiency, and the maintenance of green cover that buffers against urban heat and flooding. However, its integration into policy frameworks remains limited due to challenges such as weak institutional coordination, competing economic priorities, and governance inefficiencies. The study notes that UA holds transformative potential for climate resilience in Ghana, but its success hinges on strategic policy integration and robust implementation mechanisms. The paper proposes actionable strategies, including the formal recognition of UA zones, improved cross-agency and ministerial coordination, and the incorporation of farmer associations into decision-making processes.

城市农业日益被认为是应对当代城市挑战的有力战略，特别是在快速城市化和气候变化影响日益加剧的发展中国家。然而，在非洲城市，特别是加纳的阿克拉，普遍普及教育纳入国家战略政策和方案的作用和程度仍未得到充分探讨。本文从政策制定者的角度探讨了UA在加纳阿克拉建设气候适应能力方面的作用。它批判性地审查了普遍普及教育纳入国家政策框架的程度，并确定了阻碍其广泛采用和实施的障碍。我们采用混合方法，利用利益相关者访谈、文件分析和政策审查，以弹性理论和政治生态框架为分析视角，提供实证见解。利益相关者的观点表明，通过本地化的粮食生产来支持营养安全，利用处理过的废水来提高用水效率，以及维护绿色覆盖物来缓冲城市高温和洪水，UA有助于增强抵御能力。然而，由于机构协调薄弱、经济优先事项相互竞争以及治理效率低下等挑战，其融入政策框架的程度仍然有限。该研究指出，UA对加纳的气候适应能力具有变革性潜力，但其成功取决于战略政策整合和强有力的实施机制。本文提出了可操作的策略，包括正式承认UA区，改进跨机构和部委协调，以及将农民协会纳入决策过程。

In the calibration process of urban flood and non-point source pollution models, obtaining sufficient site-specific sensitive parameters and their variation trends remains challenging. In this study, a modified Morris screening method was established and used to evaluate the parameters of the green roof module in the SWMM model. This method involved fixing the values of all other parameters while varying a selected parameter X(i) within its defined range, applying multiple iterations of changes at a fixed percentage (10 %) to compute the corresponding model output values. The aim was to specify the impact and significance of hydrological parameters on runoff volume cut-off and water quality indicators under different return periods, and to further improve the prediction accuracy of the SWMM in simulating real rainfall events. Results revealed that Soil-T (soil layer thickness) and Surface-BH (surface layer storage depth) exhibited the highest sensitivity to total runoff production. Specifically, the sensitivity values of Soil-T exceeded 1.0 under 0.5-year and 1-year return periods, indicating its dominant role in runoff generation, while Surface-BH demonstrated a sensitivity value close to 2.0 at 0.5-year return period, showing its strong impact on peak flow. For these high-sensitivity parameters, the manual trial-and-error method was used for parameter refinement. Optimal simulation accuracy (E_NS > 0.75) was achieved when Soil-T and Surface-BH were set within ranges of 86–95 mm and 18–22 mm, respectively, across six representative rainfall events. This study provides a new method to determine the optimal parameter combinations for calibrating the SWMM model, and its high accuracy offers a scientific basis for design and optimization of urban drainage systems, particularly in response to extreme rainfall events, which is helpful to the sustainability and resilience of cities.

在城市洪水和非点源污染模型的定标过程中，获取足够的场地敏感参数及其变化趋势是一个挑战。本文建立了一种改进的Morris筛选方法，并将其用于SWMM模型中绿色屋顶模块的参数评估。该方法包括固定所有其他参数的值，同时在其定义的范围内改变选定的参数X(i)，以固定的百分比（10%）应用多次更改迭代来计算相应的模型输出值。旨在明确水文参数对不同回归期径流量截止和水质指标的影响和意义，进一步提高SWMM模拟真实降雨事件的预测精度。结果表明，土壤表层厚度（soil - t）和表层蓄水深度（surface - bh）对总产流最敏感。其中，土壤- t在0.5年和1年的回归期敏感性值超过1.0，表明其在产流中起主导作用，而地表- bh在0.5年的回归期敏感性值接近2.0，表明其对峰值流量的影响较强。对于这些高灵敏度参数，采用人工试错法进行参数细化。最优仿真精度(ENS >；当土壤- t和地表- bh分别在86-95 mm和18-22 mm范围内设置时，在6个代表性降雨事件中获得0.75)。该研究为SWMM模型的校准提供了一种确定最优参数组合的新方法，其高精度为城市排水系统的设计和优化提供了科学依据，特别是在应对极端降雨事件时，有助于城市的可持续性和弹性。
