Mangrove ecosystems play a vital role in coastal protection, biodiversity conservation, and climate regulation, yet their spatiotemporal dynamics within highly geomorphologically active deltaic environments remain insufficiently understood. This study aimed to map long-term changes in mangrove distribution, quantify mangrove gain and loss patterns, identify dominant land-cover transition pathways, and evaluate the influence of...

Bangladesh is highly vulnerable due to tropical cyclones, which frequently cause severe damages and fatalities in coastal regions of Bangladesh. This study investigates 41 major cyclonic storms from 1970 to 2021 to assess the spatial and temporal distribution of cyclone related fatalities in coastal Bangladesh. A total of 502,083 deaths and 111,885 injuries were recorded, with Chattogram, Patuakhali and Barishal districts expe...

Rangpur Division in Bangladesh lies near the active Dauki Fault, yet few studies have fully assessed its earthquake risk. Most research focuses separately on hazard or vulnerability, often ignoring mitigation and detailed spatial analysis. This study fills that gap by using a geospatial multi-criteria approach that integrates hazard, vulnerability, and mitigation indicators into one risk assessment model. Employing Geographic...

Dengue, a rapidly spreading mosquito-borne disease, poses a serious public health threat in tropical cities like Dhaka, Bangladesh—one of the world’s most densely populated megacities. In 2023 alone, Dhaka experienced its worst outbreak, recording 321,179 cases and 1,705 deaths. This study aims to assess dengue susceptibility across Dhaka using a geospatial Multi-Criteria Decision-Making (MCDM) approach. Fourteen environmental...
