Migration and climate change: towards an integrated assessment of sensitivity

This paper sets out a new approach to understanding the relationship between migration and climate change. Based on the understanding that migration is a significant, growing, but also complex phenomenon, this approach seeks to address the sensitivity of existing migration drivers in specific contexts to climate change. In contrast to existing approaches which have sought to generate global-level estimates of the numbers of ‘climate migrants’, this integrated assessment approach seeks instead to understand how and why existing flows from and to specific locations may change in the future, and provide a practical tool for climate adaptation planning. Examples of the application of this approach are provided for Ghana and Bangladesh.
