With extreme rainfall events and rapid urbanization, urban flood disaster are increasing dramatically. As a key control city in China, Changchun City suffers casualties economic losses every year due to floods. The improvement of resilience has become an important means for cities resist risks. Therefore, this paper constructs assessment model from four aspects: infrastructure, environment, society economy. Then, it quantifies infrastructure environmental vulnerability based on GIS, uses TOPSIS quantify social recoverability. Finally, k-means clustering recoverability, the was evaluated. results show that different factors have effects resilience, with low high socioeconomic recoverability more resilient face In addition, same cluster characteristics. proposed framework can be extended other regions China or countries by simply modifying indicator system according regions, providing experience regional mitigation improving resilience.

Urban environmental quality consisting of ecological, physical, and socio-economic components, often deteriorates due to rapid urbanization. Therefore, using Remote sensing GIS environment, a composite measure is applied quantify the spatial heterogeneity urban for Class-1 Indian city (Siliguri). In this study, Environmental Quality Index was constructed 15 indicators three interconnected dimensions (eco-environment, landscape built-up, socio-economy). The domains were computed utilizing Principal Component Analysis with average aggregation techniques. Exploratory Spatial Data includes Moran's I Local indicator auto-correlation, used leverage information clusters, heterogeneity, outliers based on Index. results show that Siliguri's northern, north-western, southern parts experience good quality. effectiveness employed model checked R2 (0.832), providing fit model. Moreover, pattern (except socio-economy) revealed Low-Low values predominantly clustered in centre, while High-High patterns are concentrated towards periphery. Also, value indicated existence autocorrelation non-randomness Siliguri City. obtained from analysis indicate differentiation across study area. study's outcome relevant planning, frequent monitoring quality, governance, well-being inhabitants sustainable space.

Rivers are the source of freshwater for any urban community and hence, monitoring river water is an obligatory yet challenging task. This study was conducted in a subtropical India with view developing quantitative approach to assess its quality (WQ) status. For purposes this study, samples were collected from five locations across Mahananda River main streams encompassing both urbanised non-urbanised parts Siliguri city during April June 2021 analysed fourteen common WQ indicators: pH, Temperature, Conductivity, TDS, Turbidity, Total Hardness (TH), DO, BOD, COD, NO3−, PO43−, Cl−, Fecal Coliform (FC) E. coli assessing quality. In order obtain status, present utilised modified national sanitation foundation (NSF) index (WQI) model, whereas crucial indicators identified using principal components analysis (PCA) technique. All considered compute NSF-WQI except pH TH. Most breached guideline values Bureau Indian Standards (BIS) (IS) surface water. The results revealed that "good" "medium" only suitable limited under certain conditions. findings provided evidence heavily influenced by pressures because relatively found at sampling location outer part area. research could be effective improving River's maintaining complex ecosystem ensure sustainable growth.

Background: Dhaka City, the capital of Bangladesh, has experienced rapid and unplanned urbanization over past few decades. This process brought significant challenges to public health as urban environment become a breeding ground for various risks. Understanding associations between urbanization, environment, in City is crucial developing effective interventions policies.Objectives: review paper aims uncover risks with specific focus on its impact health. The objectives this study are examine faced by city's population, explore environmental factors contributing risks, analyze socioeconomic determinants areas, evaluate existing policies governance structures, identify research data gaps, provide recommendations future interventions.Methods: A comprehensive literature was conducted gather relevant studies, articles, reports, policy documents related City. Various databases online resources were searched, selected critically analyzed extract key findings insights.The reveal that led range including air pollution, inadequate water sanitation, poor waste management, overcrowding, slums, substandard housing conditions. These strongly associated respiratory diseases, waterborne illnesses, other adverse outcomes. Socioeconomic such poverty, income inequality, limited access healthcare further exacerbate population.Unplanned implications Addressing requires interventions. Improved planning, enhanced infrastructure, better essential mitigating Furthermore, addressing disparities ensuring equitable services components

Urban flooding is a frequent disaster in cities. With the increasing imperviousness caused by rapid urbanization and rising frequency severity of extreme events climate change, hydrological status urban area has changed, resulting floods. This study aims to identify trends gaps highlight potential research prospects field South Asia. Based on an extensive literature review, this paper reviewed flood hazard assessment methods using hydraulic/hydrological models management practices advancement technology high-resolution topographic data, hydrologic/hydraulic such as HEC-RAS/HMS, MIKE, SWMM, etc., are increasingly used for assessment. vary among countries based existing technologies infrastructures. In order control flooding, both conventional physical structures, including drainage embankments, well new innovative techniques, low-impact development, implemented. Non-structural mitigation measures, improved warning systems, have been developed implemented few The major challenge process-based hydraulic was lack DEM short-duration rainfall data region, significantly affecting model’s simulation results implementation measures. Risk-informed must be immediately reduce adverse effects change unplanned flooding. Therefore, it crucial encourage emergency managers local planning authorities consider nature-based solution integrated approach enhances resilience.

The unplanned urban expansion and extreme population pressure have caused several bottlenecks for city dwellers, which been reflected in the form of inter-urban spatial inequality living conditions at household level. present study integrates GIS with a composite synthetic index to measure variation across 146 centers Eastern India (West Bengal). critically scrutinizes influence housing conditions, amenities level, asset possession on well-being households. Based these three inter-connected dimensions, condition was computed based optimum combinational model (OCCIM). Besides, provides insight into geographic distribution considering their patterns, hot spots, clusters identification. heterogeneity selected dimensions is shown maps produced using GIS. measured Moran's I global level Getis-Ord Gi * identify influential locations through spots detection condition, assets possession, scenario. Additionally, constructed UHdCLI model's consistency assessed r-squared value regression analysis (R2 = 0.815). latest findings provide realistic view variations that exist particular households concerning aspects standard life.

Urban waterlogging will harm economic development and people’s life safety; however, the risk zoning map provides necessary decision support for management of urban waterlogging, planning. This paper proposes an assessment method that combines multi-criteria analysis (MCDA) with a geographic information system (GIS). The framework includes four main elements: hazard, exposure, vulnerability, emergency response recovery capability. Therefore, we selected area Changchun City, Jilin Province as study area. Analytic Hierarchy Process (AHP) is generally accepted MCDA method, it used to calculate weight generate result hazards, responses Based principle natural disaster formation, total 18 parameters, including spatial data attribute data, were collected in this study. model results are compared recorded points, show more reliable.
