Abstract
Cyclones are one of the most common and foremost natural hazards in the world that causes extensive causalities. Bangladesh is highly vulnerable to cyclone hazard for its geographical location and socio-economic conditions. This study has aimed to analyze the historical cyclonic hazards and creating vulnerability maps and risk maps for Bangladesh. The apposite variables were selected by reviewing pertinent literatures and necessary data were retrieved for 1900 to 2015. GIS tool has been used for visualization of weighed scores for hazard, vulnerability and risk based on historical cyclones’ intensities, magnitudes, causalities and existing coping capacities. Moreover, hotspot analysis that implies Getis-Ord Gi* spatial statistics was also used in this study to identify the patterns of spatial significance and relationship of areas among their neighbors. This analysis produced Z scores from weighed variables those were proportional to the degree of vulnerability and risk. The low negative to high positive Z scores are correlative of low to high cyclone vulnerability and risk. Consequently, the weighed scores have elicited the coastal areas are in front line in terms of vulnerability and risk to cyclone. Besides, Gi* revealed that some areas are significantly risk prone for being spatially influenced by their neighbors.
Highlights
A hazard is an extreme situation that can cause or has potential negative impacts on biophysical, socio-economic and environmental aspects
Cyclone vulnerability comprises the factors of susceptibility and lack of coping and adaptive capacity [12,13]
This study was done by means of both descriptive and Geographical Information System (GIS) based statistical analysis to create cyclone vulnerable and risk maps of Bangladesh
Summary
A hazard is an extreme situation that can cause or has potential negative impacts on biophysical, socio-economic and environmental aspects. The susceptibility for being disrupt, damage and or loss of these systems and or a community or an individual to that hazard is known as the vulnerability i.e., a function of susceptibility, adaptive capacity and exposure [1,2,3,4,5,6]. It is trans-disciplinary, dynamic, change with temporal and spatial scales and depend on multi-dimensional factor and central focus point of disaster research [7,8]. Cyclone risk can be analyzed from the historical vulnerability and the existing coping and adaptive capacities [15,16]
