This book analyses the policies and approaches of the European Commission and the U.S. Government to humanitarian assistance and develops recommendations for enhancing transatlantic cooperation and mutual learning in this field. The contributions to this book were created as part of the project "Raising the Bar: Enhancing Transatlantic Governance of Disaster Relief and Preparedness." This project was mainly funded through the European Commission's pilot program on transatlantic methods for handling common global challenges and was also supported by the German Federal Ministry for Economic Cooperation and Development (BMZ).
