This book provides a timely and comprehensive examination of how cyclones and environmental stresses are changing the socioeconomic structure of one of the most vulnerable deltaic areas in the world--evidence from the Indian Sundarbans. The intricate relationships between climate-related risks and human migration trends are examined in this book, which is based on thorough research, statistical analysis, and GIS technologies. From theoretical underpinnings and bibliometric evaluations to on-the-ground assessments of vulnerability, demographic transitions, and livelihood crises, the collection spans six in-depth chapters. In addition to mapping high-risk areas and suggesting practical policy actions suited to coastal resilience and adaptive capacity, it provides evidence-based insights into the factors that influence migration. This book, which is intended for academics, policymakers, and development practitioners, increases our understanding of climate migration and its policy importance. In the context of escalating climate catastrophes, it highlights the need to rethink migration as a deliberate adaptation approach influenced by vulnerability, agency, and resilience rather than as a failure.
