Nature-based Solutions (NbS) have become crucial for enhancing urban resilience to climate change; an increasing focus has been put by scholars and practitioners in strategies to enhance their implementation. This research presents the case study of the Dési Huber István Elementary School, in Szombathely (Hungary) were a green and blue infrastructure (GBI) NbS was implemented as part of the JustNature project. This case study applied a methodological framework that integrated the principles of Service Design (SD) in the early phases of NbS implementation. The research presents how SD can enhance NbS early implementation, investigating the question: How can a service design approach support and sustain NbS implementation in educational environments?

By integrating SD principles, the study contrasts conventional top-down approaches with co-design processes, revealing that the latter can foster a more inclusive and participatory NbS design, boosting stakeholder engagement and adjusting NbS to local needs. The research highlights the importance of involving students, teachers, and the local community in the process. Based on the findings, key recommendations for effective NbS implementation in educational environments are proposed, categorized into learning integration (interactive stations, curriculum integration), student empowerment (Green Teams, environmental councils), infrastructure development (multifunctional outdoor classrooms, eco-friendly systems), and community engagement (intergenerational partnerships, living laboratory practices). This study contributes to the growing body of knowledge on innovative approaches to urban climate resilience and sustainable design practices. It also emphasizes the crucial role of educational institutions in fostering environmental awareness through practical NbS projects, which can range from urban forests and green walls to ecosystem-based management approaches. The significance of this research lies in its potential to inform both educational policy and urban planning practice, promoting resilient, sustainable, and educationally enriching urban environments.

In rapidly developing regions, especially in emerging economies like Ghana, the decline of greenery is an urgent concern. This ongoing trend leads to the significant loss of land and green areas, which worsens environmental challenges and imposes substantial costs on Local as well as state governments. This study focuses on the Wa Municipality, examining the interplay between urbanization, regulatory policies, and human behavior in influencing green space loss.

The innovation of this research lies in its integrated approach, combining qualitative insights with regression analysis to uncover complex dynamics affecting urban green spaces. Using statistical analysis and qualitative insights combined, the study revealed that while regulatory policies play a positive role in the preservation of green spaces (with a regression coefficient of Rp = 1.07, p < 0.01), both urbanization (Ur = -0.14, p < 0.05) and human behavior (Hb = -0.34, p < 0.05) significantly contribute to their decline.

These findings highlight the critical need for robust legal frameworks and active community engagement to mitigate the negative effects of environmental degradation. In addition, the study emphasizes the need of reducing sprawl in cities and offers an adaptable framework that can be modified to other urban situations both within and outside of the region, offering policymakers and city planners relevant data. By implementing the strategies identified in this research, stakeholders can promote sustainable urban development and protect vital green spaces, thereby ensuring a healthier environment for current and future generations.

Although noise pollution and control are receiving more attention from the authorities, no significant improvement is attained. Regulations on noise pollution in Vietnam are scattered, only providing general principles without clear guidance on sources, national plans, noise maps, and criminal liability. At the same pace, other developing countries face similar problems with noise pollution and control. This study aims to identify loopholes and recommend solutions for Vietnam with implications for other developing countries. The first part of this paper is a Prisma-oriented review of articles combined with hand search and recommendations by legal experts. The second part involves 15 interviews with academics and legal practitioners, environmental scientists, government officials working in environmental legislation and public health. The third part is a content analysis using software with quantitative elements. As part of the findings, the study uncovers major regulatory issues. It also offers specific recommendations such as education and public awareness enhancement, categorizing sources of noise, propaganda on noise reduction, strengthening sanctions, amending specific chapters, applying technology for detection and reporting, committing to social responsiveness/culture, among other solutions.

Air pollution is a major health problem in urban areas, influenced by traffic and atmospheric conditions. This study investigates the relationship between meteorological factors—wind direction, wind speed, boundary layer height, and atmospheric stability conditions —street trees, and PM10 concentration in three urban canyons: Avenida da Liberdade and Estrada de Benfica in Lisbon, and Marginal Tietê in São Paulo. Five years of hourly meteorological data and PM10 concentrations were analysed. Despite differences in scale and traffic volume, the results show that PM10 concentration patterns were similar in both Lisbon study areas. These areas also indicated a significant influence of atmospheric variables such as wind speed, boundary layer height, and atmospheric stability conditions. Tietê, with a higher vehicle density and different atmospheric conditions (lower wind speeds and greater atmospheric stability), presents higher PM10 peaks. Seasonal analysis revealed distinct patterns influenced by atmospheric instability, wind speed, and direction. In winter, areas with dense street tree cover had reduced PM10 levels, while those without showed higher concentrations due to increased stability. Wind direction played a crucial role, favouring the pollutant dispersal in canyons with parallel winds. The Factorial Analysis of Mixed Data method identified qualitative variables linked to the seasons, wind direction, and presence of trees. PM10 levels below the were associated with the summer and autumn period, parallel winds, and street trees, while levels above the limit were linked to winter period and areas without street trees. By integrating big data analytics with environmental monitoring, this research underscores the importance of considering the local atmospheric conditions and environmental variables in the urban air quality management. Thus, it demonstrates that the traffic volume alone does not determine PM10 concentrations; instead, the interplay of multiple factors, including meteorological conditions and urban planning, played a crucial role. This study provides valuable insights for developing effective strategies to mitigate urban air pollution and protect public health.

Climate stressors and their implications for stormwater management require evaluating climate-related threats and opportunities and implementing effective green stormwater infrastructure (GSI) systems to improve the resiliency and climate adaptation of communities, especially in urban areas. This study provides an evaluation of appropriate GSI systems that are aligned with specific climate conditions to analyze the relationship between climate types and the existing GSI practices; classify GSI implementation impediments; and identify appropriate GSI practices for different climate conditions. The existing GSI practices were critically analyzed as case studies in four different Köppen–Geiger climate regions, in view of their climate-specific GSI attributes. Our findings indicate that: (1) climate is an important factor in the design and implementation of GSI practices, and therefore, climate-specific factors need to be considered when designing effective GSI systems; (2) the implementation of climate-appropriate GSI practices can reduce climate-related stresses in communities; (3) utilizing combinations of different GSI systems improves their ability to function effectively across a wide range of climate conditions (i.e., climate events ranging from droughts to flooding); and (4) effective GSI practices can provide multiple benefits to communities (i.e., improved climate resiliency and adaptation to climate change, effective water and stormwater management practices).

The urban environment is posing substantial challenges to both human well-being and the growth of plantations. Deploying advanced urban trees that effectively interact with atmospheric pollution will be a crucial step in urban planning. However, there is a paucity of knowledge in Hungary regarding these aspects. We studied the photosynthesis activities of three commonly planted trees (Acer platanoides, Fraxinus excelsior, and Tilia tomentosa) from two locations in Budapest, as well as their potential of capturing fine particulate matter on leaf surfaces. Our results reveal that T. tomentosa has developed a denser canopy and better photosynthetic activities, hence enhancing its adaptation to the urban environment in Budapest. F. excelsior showed a higher amount of fine PM wash-off, as it has a smoother leaf surface and was subjected to influences from wind speed and precipitation, making the captured particles more easily dislodged. Whereas fine PM concentration of A. platanoides and T. tomentosa were influenced by ambient PM₁₀ and PM_2.5, which might retain on their rough and hairy leaf surfaces. Approximately 38.17 tons of fine PM could be retained on urban greenery of Budapest at any given moment, highlighting the significant ecological and economic benefits of urban greenery. However, more accurate and long-term modeling is needed to develop a sustainable strategy for maximizing these benefits.

Plastic waste poses a significant threat to the environment, public health, and aquatic life. Several methods are now under development in many studies to monitor plastic waste through earth observation satellites. These methods were successfully applied to monitor plastic litter and debris. Due to the special optical signature of plastic, it is easy to identify it in aquatic environments. But in the case of identifying plastic waste on land or in a terrestrial environment, it is very difficult as different types of land cover have their own special optical signature. Conducting field surveys could be a possible solution for monitoring plastic waste on land, but it’s costly and time-consuming. To tackle this problem, remote sensing-based observation can make a sustainable contribution. This study aims to identify plastic waste on land by the combination of Sentinel-2 imagery and two supervised classification algorithms: (1) maximum likelihood and (2) support vector classification. Two locations where plastic waste was recycled were considered for conducting this study by field observations. A total of 60 samples have been taken in this study, out of which 80% (48) have been taken as training samples and the remaining 20% (12) have been taken as testing samples, and the entire process was done using ArcGIS 10.8. This analysis revealed that algorithms used in this study successfully identify plastic waste on land, and between two algorithms, support vector classification achieves the highest accuracy (93%). Bands 6, 7, and 8 show higher spectral reflectance for plastic. The finding suggests that supervised algorithms can be used to identify plastic waste on land. Other algorithms, high-resolution satellite imagery, and a larger dataset are necessary to identify smaller plastic waste on land. This study will help policymakers and decision-makers at national and local levels to identify and management of plastic waste in a sustainable way.

塑料垃圾对环境、公众健康和水生生物构成重大威胁。目前，许多研究正在开发几种方法，通过地球观测卫星监测塑料废物。这些方法已成功地用于监测塑料垃圾和碎片。由于塑料具有特殊的光学特征，在水生环境中很容易识别。但在陆地或陆地环境中识别塑料垃圾的情况下，由于不同类型的土地覆盖具有各自特殊的光学特征，因此非常困难。进行实地调查可能是监测陆地上塑料垃圾的一种可能的解决方案，但它既昂贵又耗时。为了解决这一问题，基于遥感的观测可以做出可持续的贡献。本研究旨在结合Sentinel-2图像和两种监督分类算法：(1)最大似然和(2)支持向量分类，对陆地上的塑料垃圾进行识别。通过实地观察，考虑了回收塑料废物的两个地点进行这项研究。本研究共采集了60个样本，其中80%（48个）作为训练样本，其余20%（12个）作为测试样本，整个过程使用ArcGIS 10.8完成。分析表明，本研究使用的算法成功识别了陆地上的塑料垃圾，两种算法中，支持向量分类的准确率最高（93%）。6、7、8波段对塑料表现出较高的光谱反射率。这一发现表明，监督算法可以用来识别陆地上的塑料垃圾。其他算法、高分辨率卫星图像和更大的数据集是识别陆地上较小的塑料垃圾所必需的。这项研究将帮助国家和地方各级的政策制定者和决策者以可持续的方式识别和管理塑料废物。

Negative air ions (NAIs) play an important role in human well-being, serving as key indicators of air cleanliness and contributing to both psychological and physiological health. This study aims to investigate the factors influencing NAI concentration in urban and suburban forest parks, enhancing our understanding of the correlation between NAIs and environmental factors. Songjiacheng Urban Forest Park and Runyang Wetland Suburban Forest Park in Yangzhou City were selected as the subjects of this research, and continuous measurements of NAI concentration were conducted over a three-year period. Additionally, seven meteorological factors were monitored. A random forest model was employed to analyze and compare the data from the two forest parks, identifying the environmental factors with significant impacts on NAI concentration. The results indicate that in Songjiacheng Urban Forest Park, NAIs exhibited significant sensitivity to temperature, followed by atmospheric pressure. Conversely, in Runyang Wetland Suburban Forest Park, PM2.5 (particulate matter 2.5) exerted the greatest impact on NAIs, followed by humidity. We conducted a thorough analysis of data to explore the intricate connections between negative air ions and a variety of environmental factors within two urban forest parks. Our findings have significantly broadened our perspective on the characteristics of Negative Air Ions (NAIs) and their management implications within these urban green spaces. This enhanced understanding is pivotal for developing more effective strategies for environmental stewardship and the preservation of these vital urban ecosystems.

空气负离子（NAIs）是空气清洁度的关键指标，对人类的身心健康起着重要作用。本研究旨在探讨影响城市和郊区森林公园空气负离子浓度的因素，从而加深我们对空气负离子与环境因素之间相关性的理解。本研究选取了扬州市宋家城城市森林公园和润扬湿地城郊森林公园作为研究对象，对其进行了为期三年的NAI浓度连续测量。此外，还对七个气象因子进行了监测。采用随机森林模型对两个森林公园的数据进行了分析和比较，找出了对NAI浓度有显著影响的环境因素。结果表明，在宋家城城市森林公园，NAI对温度有明显的敏感性，其次是大气压力。相反，在润扬湿地郊区森林公园，PM2.5（颗粒物2.5）对净空气指数的影响最大，其次是湿度。我们对数据进行了深入分析，以探索两个城市森林公园内空气负离子与各种环境因素之间的复杂联系。我们的研究结果极大地拓宽了我们对空气负离子（NAIs）特性及其对城市绿地管理影响的认识。这种进一步的了解对于制定更有效的环境管理策略和保护这些重要的城市生态系统至关重要。

The United Nations Environment Programme (UNEP) released design indexes for sustainable neighbourhoods, including self-sufficiency, community plot ratio and civic generosity. However, they are developed from an urban planning perspective and not researched in relation to: a) the citizen perspective and b) how citizen interactions can contribute to the environment. Therefore, this research tests a novel set of indexes with an underused method of ethnographic video interviews with 14 citizens of a known sustainable neighbourhood in Stockholm, Sweden. A thematic analysis conducted on 28 h of interview data collected over a 4-week period yielded 5 main themes, from outdoor public spaces. Self-sufficiency findings suggest that citizens 1) perceive small scale self-sufficiency to be challenged by large scale structural efficiency and 2) circular actions with food waste to biogas can develop the self-sufficiency index further. Community plot ratio findings suggest that citizens 3) perceive community spaces to be accessible for all but not used by all. Civic generosity findings suggest citizens 4) perceive an imbalance between self-interests of the individual versus collective interests of the community, while 5) experienced citizens feel personally responsible to pioneer civic generosity interactions. UNEP indexes for designing neighbourhoods can define local sustainability, however, our findings support this, only if they can be acted upon by the citizens who live there.

联合国环境规划署（UNEP）发布了可持续街区的设计指数，包括自给自足、社区容积率和公民慷慨度。然而，这些指标都是从城市规划的角度制定的，并没有对以下方面进行研究：a) 公民视角；b) 公民互动如何对环境做出贡献。因此，本研究通过对瑞典斯德哥尔摩一个已知的可持续街区的 14 位市民进行人种学视频访谈，对一套新颖的指标进行了测试。通过对 4 周内收集的 28 小时访谈数据进行主题分析，得出了户外公共空间的 5 大主题。自给自足的研究结果表明：1）市民认为小规模的自给自足受到大规模结构效率的挑战；2）将食物垃圾转化为沼气的循环行动可以进一步提高自给自足指数。社区地块比率调查结果表明，公民 3) 认为社区空间可供所有人使用，但并非所有人都会使用。公民慷慨的调查结果表明，公民 4) 认为个人利益与社区集体利益之间存在不平衡，而 5) 有经验的公民认为个人有责任开拓公民慷慨的互动。联合国环境规划署（UNEP）的街区设计指数可以确定当地的可持续性，然而，我们的研究结果也支持这一点，但前提是居住在当地的市民能够对这些指数采取行动。

The motivation of the present review is to comprehend the interaction between primary and cascading hazards in urban areas, aiming to create a novel holistic approach that improves urban sustainability based on individuals’ preferences for urban ecosystem services (ES) preservation. The objectives are to monitor valuation studies revealing willingness to pay (WTP) for urban challenges, assess non-marketed valuation studies, and examine hazard interactions and their impacts. Using data from Environmental Valuation Reference Inventory and Ecosystem Services Valuation Database, 80 studies on 220 WTP values were analyzed in the period 2000–2023. The findings show a mean WTP (MWTP) of 142€ for heatwave mitigation and 76€ for air pollution. Moreover, in terms of cascading hazards, the highest MWTP was for population density (298€), followed by biodiversity loss (96€), health issues (63€), and lastly by traffic and noise with 42€. Biodiversity loss emerged as the top concern, urging policymakers to enhance urban resilience. The review contributes to the latest literature regarding the MWTP for ES in urban settlements and provides relevant policy implications in order to improve urban resilience, safeguarding both human health and the natural environment.

本综述的动机是理解城市地区原生危害和级联危害之间的相互作用，旨在创建一种新颖的整体方法，根据个人对城市生态系统服务 (ES) 保护的偏好来改善城市的可持续性。目标是监测揭示城市挑战支付意愿（WTP）的估值研究，评估非市场估值研究，并检查危害的相互作用及其影响。利用环境估值参考目录和生态系统服务估值数据库中的数据，对 2000-2023 年期间有关 220 个 WTP 值的 80 项研究进行了分析。研究结果表明，热浪缓解的平均 WTP（MWTP）为 142 欧元，空气污染的平均 WTP（MWTP）为 76 欧元。此外，就逐级危害而言，人口密度的 MWTP 值最高（298 欧元），其次是生物多样性丧失（96 欧元）、健康问题（63 欧元），最后是交通和噪音，为 42 欧元。生物多样性丧失成为人们最关心的问题，这敦促决策者提高城市的抗灾能力。本综述为有关城市住区环境、社会和生态影响的 MWTP 的最新文献做出了贡献，并提供了相关的政策影响，以提高城市复原力，保护人类健康和自然环境。
