What are the ethical issues involved in providing humanitarian aid? What is the real impact of humanitarian groups? Medecins Sans Frontieres sought to answer these questions in the Perception Project, a study that spanned four years and more than ten countries. MSF interviewed close to 7,000 people in order to understand the ways that patients, populations, authorities, and communities perceive the Nobel Peace Prize-winning organization's principles and medical practices. While the quality of its medical action is renowned and praised, MSF struggles with the ability to respond to crises, the safety of its teams, and the development of effective interactions with diverse populations and authorities. Dilemmas, Challenges, and Ethics of Humanitarian Action is a series of reflections on the Perception Project that presents the insights and analyses of authors from a diverse array of fields including communications, ethics, medicine, humanitarian studies, and political science. At a time when humanitarian aid is under increasing scrutiny, this book provides insiders' perspectives on how one of largest and most influential non-governmental medical organizations can better serve those in need.
