Therefore, this study focuses on developing a novel WQI model for 4 Dhaka-based rivers namely Buriganga, Turag, Balu, and Shitalakhya following PCA as a method for selecting and weighting water quality parameters. The dataset includes 12 water quality parameters from 19 sites of these rivers sourced from the Department of Environment (DoE), Bangladesh. Correlation analysis followed by PCA, was conducted to decrease the parameter count from 12 to 7. The Measure of Sampling Adequacy (MSA) was found to be 0.853 in the Kaiser-Meyer-Olkin (KMO) test and Bartlett’s test of sphericity was significant at an alpha level of 0.05 indicating the dataset was suitable for factor analysis. Sub-indexing was introduced with the quality rating curves provided by the National Sanitation Foundation (NSF)-WQI model and modified rating curves for specific parameters with statistical dispersion. The calculated WQI values for 209 samples ranged from 36 (Bad) to 82 (Good) on a scale of 100. More than 70 % of the samples were in the medium or bad, and the rest were in the good category. The trend in WQI across the rivers indicated higher values during the wet season, attributed to the dilation from local rainfall. By incorporating a well-distributed dataset spanning several years, this statistical approach effectively minimizes the subjectivity and bias in developing WQI models for rivers in Dhaka, contributing to more robust future model development. Moreover, this study introduces a modern approach for assessing the river water quality of Dhaka city that can be incorporated into the river pollution control strategies.</p></div>","PeriodicalId":52395,"journal":{"name":"City and Environment Interactions","volume":"23 ","pages":"Article 100150"},"PeriodicalIF":3.3,"publicationDate":"2024-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590252024000102/pdfft?md5=9646c18cb8ccab820d4530f7e996b7a9&pid=1-s2.0-S2590252024000102-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140777563","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A precondition to develop adaptation strategies to counteract adverse effects of heat in cities is to gain knowledge about the urban temperature distribution. One approach that has been applied in various cities is the implementation of dense urban temperature measurement networks. Since financial resources are usually limited, such networks consist of cost-effective measurement devices whose (daytime) data quality is prone to errors due to radiative influences. This was also the case in Zürich, Switzerland, where an urban temperature network with 272 measurement stations was operated from 2019 to 2021. In this study, we present a radiation correction method to enhance the data quality for practical use. Applying the proposed correction method led to a reduction in mean RMSE from 1.47 K to 0.57 K and in the overall mean bias from +0.88 K to +0.04 K. Following from that, we use the corrected database for two application cases: i) As a spatially and temporally high-resolution validation dataset for the physics-based large eddy simulation model PALM and ii) as input data for a geostatistical land use regression model. The analysis shows that the daytime radiation correction is crucial to detect the negative bias of the PALM model, which is most pronounced in the highly built-up area of Zürich, and to enhance the quality of the daytime land use regression. The developed radiation correction presented in this study can also be applied for other urban temperature networks that are facing similar challenges.</p></div>","PeriodicalId":52395,"journal":{"name":"City and Environment Interactions","volume":"23 ","pages":"Article 100148"},"PeriodicalIF":3.3,"publicationDate":"2024-04-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590252024000084/pdfft?md5=9152e9288273392384e980fcf5f0aa7c&pid=1-s2.0-S2590252024000084-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140549302","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

While the area functions as a multi-faceted public asset, encompassing both Green Open Space (GOS) and Blue Open Space (BOS), the actual utilization of these spaces reveals disparities. Employing mixed methods, this study aims to holistically capture the complexities surrounding utilizing Setu Babakan’s blue-green spaces from the vantage points of visitor perceptions, street vendors, and governmental policies. The study found that both visitors and street vendors were highlighting the need for equitable access to this vital public amenity. Factors such as accessibility and population density of vendors within the neighborhood area complicate the quest for socio-spatial equality. The presence of 6 (six) distinct types of <em>warung</em>s or street vendor stalls, which spontaneously emerge in the transitional zones between blue-green public spaces and private community lands, underscores the local government’s challenge in crafting policies that achieve legal and inclusive socio-spatial fairness. This study suggests that Setu Babakan embodies a unique confluence of cultural, social, and environmental values, offering a blueprint for how multifunctional public spaces can cater to diverse urban needs while fostering community well-being. As such, it calls for regulatory clarity, suggesting implementing formalized guidelines like temporary permits or designated zones to harmonize the competing demands of the informal economy and environmental sustainability.</p></div>","PeriodicalId":52395,"journal":{"name":"City and Environment Interactions","volume":"22 ","pages":"Article 100137"},"PeriodicalIF":3.3,"publicationDate":"2024-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590252023000399/pdfft?md5=9bef428e73010f44ae92e747576393c6&pid=1-s2.0-S2590252023000399-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140555167","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Urban planning for flood resilience under technical and financial constraints: The role of planners and competence development in building a flood-resilient city in Matola, Mozambique","authors":"José Lourenço Neves","doi":"10.1016/j.cacint.2024.100147","DOIUrl":"https://doi.org/10.1016/j.cacint.2024.100147","url":null,"abstract":"<div><p>Today, urban flood resilience constitutes an academic and political discourse as well as a ‘proposed state’ to be achieved within urban management, planning, and development. Matola, a major Mozambican coastal city, has witnessed many floods, mainly caused by rainfall, the most devastating of which happened in 2000. This study analyses the actions the urban planners took during that major flood event, what flood mitigation and adaptation strategies and measures for increased flood resilience they have developed since that flood event, and the contribution of urban planning to building flood resilience under financial and technical constraints. The study is based on interviews with 32 urban planners from Matola and observations in the field. In addition to financial limitations, the main challenge in promoting flood resilience in Matola is the deficient and insufficient coordination in mitigation and adaptation actions among urban planners, political elites, and members of low-income urban communities, who use floodplain areas for purposes that contradict resilience-building actions. During the 2000 floods, mitigation actions were carried out by rescuing people and goods and placing them in accommodation centres. After the 2000 floods, gradual adaptation strategies and measures were carried out, such as hiring and training staff, designing a new urban plan, gradual resettlement, opening drainage channels, and allocating water pumping systems in some areas to promote flood resilience. The study concludes that urban planning contributed significantly to the building and promotion of flood resilience in Matola: the strategies and measures taken so far have contributed significantly to reducing the exposure and vulnerability to flooding of the population, their assets, and urban infrastructure, as well as improving the ecosystem in lowlands and coastal protection wetlands. The study brings a contribution from retrospective and prospective resilience thinking to the debate on building and promoting resilience in urban socio-ecological systems, showing the role of urban planners, and planning and management activity since the 2000 floods, and perspectives on the future. The study demonstrates that the development of competences or technical skills to plan and manage strategies and measures to promote resilience is a key factor in promoting socio-ecological resilience.</p></div>","PeriodicalId":52395,"journal":{"name":"City and Environment Interactions","volume":"22 ","pages":"Article 100147"},"PeriodicalIF":3.3,"publicationDate":"2024-03-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590252024000072/pdfft?md5=07d6e1070fc4ff4afb59e98869a95adf&pid=1-s2.0-S2590252024000072-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140320412","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Studying these challenges separately is a common practice, ignoring the interdependencies between the sectors of the city and limiting the environmental impact assessments to the local level. This perspective has led to biased assessments and an underestimation of urban environmental impacts because interactions between the city and other territories have been omitted. Therefore, in this work OLCA is proposed to be used as a systematic and holistic approach to support decision-making in cities. The goal of this study was to evaluate Mexico City Water-Energy-Food (WEF) Nexus environmental impacts using Organizational Life Cycle Assessment (OLCA), aiming to identify activities with the highest mitigation potential.&lt;/p&gt;&lt;p&gt;Two methodological modifications to OLCA were proposed: considering WEF Nexus as the reporting organization and as the axis to define the system boundaries. These modifications allowed to evaluate of both local and federal government-controlled and private-sector activities. WEF Nexus direct activities (within Mexico City), food, water and energy supply indirect upstream activities, and indirect downstream activities, such as waste and wastewater treatment and disposal were evaluated (outside Mexico City).&lt;/p&gt;&lt;p&gt;Indirect activities account for 13% to 60% of total impacts in the evaluated categories, proving the importance of using OLCA-focused methodologies to include indirect urban impacts when performing environmental assessments, to avoid underestimations regarding such impacts.&lt;/p&gt;&lt;p&gt;Coupling OLCA with WEF Nexus approach allowed to broaden the scope of the analysis and identify critical points at local, regional, and federal levels. At a local scale, the highest environmental impacts are related to the transporting sector fuel consumption in Mexico City and for water sector due to the hydric stress currently faced by the city. At a regional level, food production had an impact mainly due to its high demand for water and due to excessive application of fertilizers. At the federal level, it was observed that as long as the high participation of fuels in the country's energy mix is maintained, it will continue to cause high associated environmental impacts.&lt;/p&gt;&lt;p&gt;In the same manner, recommendations were identified to guide stakeholders in making informed decisions to mitigate the main environmental impacts. At the federal scale, it has been recommended that the share of renewable in electricity generation must increase to satisfy Mexico City electric energy needs and at the same time mitigate indirect impacts associated with fossil fuels. At a regional scale, it is recommended that the city influences the food systems and promotes a higher efficiency in irrigation methods and fertilizer use. At local scale, it has been identified as a key aspect the importance of promoting the use of net zero-emission transport and boosting the use of compost for food growing.&lt;/p&gt;&lt;p&gt;The ","PeriodicalId":52395,"journal":{"name":"City and Environment Interactions","volume":"22 ","pages":"Article 100143"},"PeriodicalIF":3.3,"publicationDate":"2024-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.sciencedirect.com/science/article/pii/S2590252024000035/pdfft?md5=304f8f4aea07ccb06e0c60c170fe8498&pid=1-s2.0-S2590252024000035-main.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139694252","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

It aims to aid in structuring thinking for understanding and implementing Sustainable Development Goals (SDGs) within urban settings, using Norway as a case study but with a clear potential for broader applications. To achieve this, a comprehensive literature survey was conducted to gain insight into how urban environmental sustainability is conceptualized and operationalized in Norway. This involved assessing the key environmental challenges, as well as the strategies and action plans associated with them. Standardized sustainable cities' indicators served as references, which were then tailored to the municipal level to address the identified environmental challenges specific to Norwegian cities. Furthermore, the study discussed the proposed indicators for tracking the progress and state of these specific environmental challenges. In doing so, it establishes a foundation for comprehending environmental issues and establishing connections between indicators and environmental strategies and action plans in the urban sustainability context. Importantly, the methodologies and indicators we have unveiled in this study are designed to be applicable to cities beyond Norway, offering a scalable and adaptable approach for evaluating environmental challenges internationally. This work proposes a novel approach for evaluating the status and trends of environmental challenges by employing targeted indicators.
