With more than 145 million people in need of humanitarian assistance, more than 65 million people forcibly displaced, growing risks of climate-driven natural hazards, food insecurity on the rise and four countries struggling to stave off famine, the global humanitarian system faces exceptional challenges. As needs outstrip funding, it is clear that traditional ways of doing business will not suffice. These global crises cannot be addressed without rethinking the link between humanitarian response and development assistance. CGD is delighted to welcome Mark Lowcock, less than two months into his new position as the Emergency Relief Coordinator and Under-Secretary-General for Humanitarian Affairs. As the UN system’s lead for global relief activities, he is charged with coordinating how humanitarian agencies respond and work together to address global emergencies. After delivering remarks, he will join CGD president Masood Ahmed to discuss successes, challenges, priorities, and reforms for the global humanitarian system in a time of urgent and growing need.
