Internal displacement is a major societal challenge worldwide, with far-reaching consequences for the tens of millions of people displaced annually as well as for affected communities and society as a whole. As such, the low level of interest in this phenomenon among researchers and policymakers represents a puzzle. A new Handbook of Internal Displacement seeks to change this situation by raising the profile of the issue for researchers, teachers, policymakers, funders, humanitarian workers and development actors and addressing the wide range of dynamics, debates and challenges that internal displacement entails. This groundbreaking publication provides extensive regional analysis of displacement in Africa, the Americas, Asia, Europe and the Middle East, and offers a distinctive global vision of “internal displacement” as an emerging field of research and practice.
