Displacement caused by climate change is an area of growing concern. With current rises in sea levels and changes to the global climate, it is an issue of fundamental importance to the future of many parts of the world. This book critically examines whether States have obligations to protect people displaced by climate change under international refugee law, international human rights law, and the international law on statelessness. Drawing on field work undertaken in Bangladesh, India, and the Pacific island states of Kiribati and Tuvalu, it evaluates whether the phenomenon of 'climate change-induced displacement' is an empirically sound category for academic inquiry. It does so by examining the reasons why people move (or choose not to move); the extent to which climate change, as opposed to underlying socio-economic factors, provides a trigger for such movement; and whether traditional international responses, such as the conclusion of new treaties and the creation of new institutions, are appropriate solutions in this context. In this way, the book queries whether flight from habitat destruction should be viewed as another facet of traditional international protection or as a new challenge requiring more creative legal and policy responses.
