 A lot of new evidence is shed in light on the complexities of migration between and within West and North Africa and across the Mediterranean. We now have a better, more nuanced understanding of the risks as well as the opportunities characterizing migration in this area of the world. This is why IOM's Global Migration Data Analysis Centre decided to focus on this bigger picture in its new public. The new volume provides comprehensive, fact-based account of migration from and within these regions over the past two years, from recent trends and data to development outcomes from risk and vulnerabilities to governance at local, national and regional levels. This volume is a result of a highly collaborative process and features 38 different contributions from across the migration spectrum, including IOM offices, international organization, research institutes and civil society organizations. One of the key takeaways of the volume is that people often move in order to contribute to their own and to their community's resilience and development. Their ability to do so depends on their socioeconomic status and on the access they have to safe and to regular migration pathways, which are established by countries. These aspects should receive more attention in national and regional policies as well as in policy dialogues between Europe and Africa. An additional important message on the report is that we need to promote a better understanding of the evidence and use of that evidence to inform policies and monitor their impacts. We hope that the breadth and variety of perspectives and analyses included in this volume will help to promote more coherent, forward-looking and sustainable policy approaches.
