In this important collection, Professor Hugo draws together key articles and papers by leading scholars and agencies which investigate the current and future effects of climate change on migration. Topics covered include the impact of climate change on the movement of people within and across countries, the economic and social effects of the forced displacement and resettlement of migrants, the flows of migration resulting from environmental disasters, the risks of conflict and the implications of climate change for vulnerable areas e.g deltas, atolls and coastal regions. The title concludes with an examination of what the policy responses of governments and international agencies are and should be.
