Deutsche Post DHL Group and the United Nations Office for the Coordination of Humanitarian Affairs (OCHA) have issued a publication - Combining Capabilities - which showcases the growing importance of public-private partnerships in humanitarian action. The publication, launched during the World Humanitarian Summit in Istanbul, illustrates a variety of innovative and effective case studies. It demonstrates that public-private partnerships are essential for addressing humanitarian needs in today’s world. It also sheds light on how such partnerships work in practice, what challenges exist, and what makes them successful in the long run. Case studies such as the Group's Disaster Response program GoHelp show which key factors are critical for a successful public-private partnership.
