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

“…The 2011 Indian Population Census is the most recent and extensive census conducted thus far, notable for its incorporation of housing conditions, asset ownership, and amenities data at the neighbourhood level within urban areas. This Indian dataset is among the world's largest and most comprehensive information and is known for its robust data quality, owing to meticulous data collection, validation protocols, and stringent confidentiality measures (Roy et al ., 2023a; Majumder et al ., 2023). Geographically, it encompasses the entirety of India, spanning both urban and rural regions, structured hierarchically, from the national level to local divisions.…”

Darjeeling, renowned as the ‘Queen of the Himalayas’, is one of the high‐altitude towns in India, distinguished by its exceptional topography and picturesque landscape. Given the challenges posed by limited land availability, susceptibility to natural hazards, and the need for context‐specific housing interventions in such hilly terrains, understanding housing conditions becomes paramount. Thus, this research explores the spatial patterns and heterogeneity of urban housing wellness in Darjeeling's hilly urban centre. A comprehensive assessment was conducted utilizing 15 key indicators. Three principal indices were formulated: Residence Quality, Residence Essential Services, and Residence Asset & Possession, culminating in the Urban Housing Wellness Index (UHWI). The index construction employed the Geographically Weighted Principle Component Analysis (GWPCA) technique. In further analysis, Univariate Local Indicators of Spatial Association (LISA) were used to determine clustering and spatial dependence, while Moran's I was utilized to gauge the spatial autocorrelation of housing conditions. A notable clustering pattern and spatial autocorrelation was observed in the urban housing wellness of the study area. The present study offers novel insights into the intricate dynamics of housing conditions in unique hilly terrains.

“…However, these methods often encounter challenges in systematically integrating multi-criteria decision-making and expert knowledge. The applicability of the Analytic Hierarchy Process (AHP) method in rapid and regional assessments is promising 40 , 41 . By employing AHP, this study aims to enhance the accuracy and reliability of land subsidence risk assessment by effectively integrating diverse sources of information and expert opinions.…”

This study focuses on the Yongqiao District in Suzhou City, Anhui Province, China, aiming to analyze the current situation of ground settlement and its influencing factors in the area. The selected risk indices include settlement rate, cumulative settlement amount, groundwater level drop funnel, thickness of loose sediment layer, thickness of soft soil layer, and the number of groundwater extraction layers. Additionally, vulnerability indices such as population density, building density, road traffic, and functional zoning are considered. An evaluation index system for assessing land Subsidence risk was established. The risk evaluation of land Subsidence was conducted using the Hierarchical analysis-composite index method and ArcGIS spatial analysis, The evaluation results show that the area of higher risk area is about 2.82 km2, accounting for 0.96% of the total area, mainly distributed in the area of Jiuli village, Sanba Street. The middle risk area is distributed around the higher area, with an area of about 9.18 km2, accounting for 3.13% of the total area. The lower risk areas were distributed in most of the study area, covering an area of 222.24 km2, accounting for 75.82% of the total area. The low risk assessment area is mainly distributed in Bianhe Street and part of Zhuxianzhuang Town, with an area of about 58.88 km2, accounting for 20.09% of the total area. The findings of this study are not only crucial for informing local policies and practices related to land use planning, infrastructure development, and emergency response but also enhance our understanding of the complexities of land Subsidence processes and their interactions with human activities, informing future research and practice in environmental risk assessment and management.
