This open-access book critically explores climate-related human mobility in the Asia-Pacific region, focusing on the legal and policy protections for climatically displaced migrants (CDMs) through an interdisciplinary, human rights-based approach. It examines both theoretical and policy dimensions while incorporating empirical studies to highlight protection gaps. By presenting multiple case studies, the book advocates for a legal framework grounded in human rights to address climate-induced displacement, migration, and forced immobility. It integrates perspectives from academia, national human rights institutions, and government officials, offering insights into policy processes, disaster risk reduction, climate change adaptation, emergency preparedness, and planned relocation.
