Abstract:Multiple hazards study is imperative because of the increasing frequency of natural calamities brought on by climate change. Evaluation of the element affected by numerous risks requires analysis of the exposed elements. Without the exposed elements, a hazard's severity cannot be comprehended. The impact of hazards also depends on the coping capacity of the exposed population. It has been noted that marginalised groups, like refugees, are more affected by dangers because they lack freedom and are subject to various restrictions imposed by the host nation. In 2016, a massacre carried out by Myanmar militants drove 700,000 Rohingyas from Myanmar to Bangladesh. They took refuge in the Cox's Bazar. Cox's Bazaar is a hilly terrain on the coast of Chittagong, Bangladesh. Its proximity to the Bay of Bengal and topography subject it to several risks, including cyclones, floods, and landslides. Therefore, an initiative was taken by the Government of Bangladesh to relocate Rohingya refugees to Bhashan Char-an island in the Bay of Bengal. Hence, the research focuses on the multi-hazard exposure analysis and risk perception of the Rohingya refugees at Cox's Bazar and Bhashan Char. The study employs the mixed method approach where quantitative information from secondary sources and qualitative knowledge from field survey and experts' interview is used to make a multi-hazards exposure index using Analytical Hierarchical Process (AHP). The resultant exposure index is used to quantify the shelter and population subjected to multi-hazards. The field survey data was utilised to generate income and employed with the exposure index to explore the relationship between multi-hazard Exposure and coping capacity. Geospatial methods such as Euclidian distance, Inverse distance weightage (IDW), Cost and Benefit Analysis (CBA), Spatial autocorrelation, and Zonal statistics were employed to prepare data for the AHP analysis. Then the field survey data and expert-written interviews were used to calculate the weightage of the indicators for AHP. The field survey results were utilised to understand how Rohingya refugees perceived Risk and made decisions concerning Bhashan Char. Various statistical techniques such as descriptive statistics, cross-table, and correlation analysis were used to analyse the survey data. The results identify multi-hazard exposure zone and individual shelters with a specific level of Exposure. The finding shows that the risk perception of Rohingya refugees depends on their socio-economic circumstances. The research's findings help disaster risk management organisations locate exposed shelters and deliver assistance in accordance with the degree of Exposure. The findings on risk perception help the government and NGOs comprehend the psychological and emotional drivers of people's attitudes toward risk perception and decisions to relocate.
