Sustainable embankment contribute to a sustainable economy: The impact of climate change on the economic disaster in coastal area

Purpose The purpose of this study is to examine the relationships between climate change, economic disasters, disaster management, and sustainability in the coastal areas of Bangladesh. Specifically, it aims to investigate how disaster management mediates the impact of economic disasters on sustainable embankment and economic sustainability, providing insights for enhancing resilience in these vulnerable regions. Method This study employs a quantitative research approach to analyze the relationships among climate change, economic disasters, disaster management, and sustainability in coastal areas of Bangladesh. Data collected through structured surveys administered to key stakeholders in the region, including local residents, government officials, and disaster management experts. To analyze the data, Structural Equation Modeling (SEM) was used. Findings The results show that climate change has a positive (beta = 0.277) and statistically (p value < 0.05) significant impact on economic disasters in coastal areas, and disaster management is also significantly (beta = 0.172, p value < 0.05) related to mitigating economic disasters. Furthermore, the result demonstrates that disaster management has a positive impact on sustainable embankment (beta = 0.145) and sustainable economy (beta = 0.150) development. Moreover, the authors also find that disaster management significantly (p value < 0.05) mediates the relationship between economic disaster and sustainable embankment and economy development. These findings highlight the necessity for policymakers to give integrated disaster response plans and resilient infrastructure funding top priority in order to improve coastal regions' sustainability and economic stability. Originality value This study contributes to the existing body of knowledge by highlighting the direct relationship between embankment resilience and sustainable economic growth and how both can assist lessen the ongoing impacts of climate change. Moreover, this relationship offers the groundwork for policy interventions specific to Bangladesh's coastal regions by highlighting the significance of infrastructure resilience in mitigating economic disasters.
