This study investigates the intersection of environmental and humanitarian law violations in the coastal areas of Bangladesh, focusing on the implications of climate change-induced disasters on vulnerable communities. A quantitative survey was conducted, with 150 respondents representing coastal regions, to gather data on the prevalence of environmental degradation, climate-induced displacement, and human rights violations. Findings reveal a significant correlation between environmental hazards, such as cyclones and sea-level rise, and the displacement of coastal populations, exacerbating socio-economic vulnerabilities and human rights abuses. The study employs a quantitative methods design, analyzing survey data of legal frameworks, policy documents, and scholarly literature. The data was analyzed through Smart PLS 4 for Structural Equational Model (SEM). The purpose of this research is to elucidate the complexities surrounding legal enforcement, policy implementation, and grassroots initiatives aimed at addressing environmental and humanitarian challenges in coastal areas. By providing empirical evidence and insights into the lived experiences of affected communities, this study aims to inform evidence-based policy interventions, legal reforms, and humanitarian strategies to enhance resilience and protect the rights of coastal populations facing the impacts of climate change and environmental degradation.
