This book challenges the notion that migration governance is a fixed framework, arguing instead that it evolves in response to diverse, often unpredictable factors over time. Through a collection of insightful case studies from various geopolitical settings, this volume offers a deep dive into the evolution, key milestones, challenges, and distinctive characteristics of migration management policies. By exploring how these policies are shaped, implemented, and reformed under the influence of both internal dynamics and external pressures, the book reveals the fluid and dynamic nature of migration governance. Readers will gain a nuanced understanding of how migration policies are adapted across different countries and regions, shaped by unique sociopolitical contexts and evolving global trends.
