Climate change has been fueling migration, and, according to some policy reports, there could more than one billion climate migrants/refugees across the world by 2050. In South Asia, disasters, environmental degradation, and climate change are increasing the number of migrants every year. In South Asia, like other parts of the world, migrants and displaced people mainly move within their respective countries, but some cross the porous border. At most places, the migrants and displaced people face hostile situation as they are not welcome by their local host population. The chapters in the book highlight the challenges and inadequacies of governments and communities in protecting the environment as well as the disproportionate effect that climate change has on the poor and marginalized groups. The book also discusses the gendered experiences of climate-related migrations and policy measures which need to be implemented to counter forced displacements and environment degradation along with the legal and institutional resources which could help mitigate climate change and protect climate refugees. This book will be of interest to students and researchers of development studies, ecology and environment, migration, sociology, law and governance, human ecology, climate change and economics.
