DG HOME commissioned a study to Ecorys to assess the validity of communication campaigns as an effective tool for migration management. The study presents best practices from 20 existing campaigns, and seeks to highlight ways to improve the quality and effectiveness of future campaigns. The final report presents the cumulative results of the two phases of this study.

The recommendations are complemented with a ‘toolkit’ to help implementers and donors resolve the most common issues uncovered
