Exposure, Sensitivity and Adaptability of Climate Vulnerability using Ultra‐Poor Graduation Interventions in the Coastal Region of Bangladesh: A Study in the Bauphal Upazilla of Patuakhali District

A cross-sectional study of climate change vulnerability (CCV) on 205 ultra-poor households of Bauphal Upazila of southern coastline were conducted. Exposure, sensitivity and adaptation practices were evaluated for this study. About 70% families of treatment group provided positive feedback to adjust to CCV. The endline CCV had dropped by 18% compared to baseline score. Exposure and adaptable capacity had grown by 14% and 13%, respectively. Besides, endline sensitivity was dropped 11% than baseline score. The adaptation indices for social organizations, personal savings, training on climate change topics, and loan facilities from various bank types were all high (>0.90). Significant progress has been made in the community's volunteerism for local development projects, during disasters. Under the treatment condition, there was a significant improvement in livestock farming (0.20), planted trees (0.34), rainwater harvesting (0.23), GO-NGOs' support (0.37), and social event attendance (0.34). However, understanding of farm services (0.107) and the early warning system/messages (0.14) showed a discernible improvement. The sequence of adaptation measures to climate change are as follows: livelihood>livestock>social and financial security>health-sanitation>water security>knowledge on comprehension warning systems,> social inclusivity. The results of this study may assist policymakers in developing appropriate measures prior developing a disaster management framework for coastal areas.
