Given the increase in humanitarian and emergency situations related to disease outbreaks and public health emergencies, natural disasters, and refugee situations and violent conflict, UNICEF C4D is increasing efforts to synthesize and learn from these experiences to regularly inform technical support to national and local partners, facilitate cross-regional learning and strengthen our approaches to humanitarian action and emergency response including accountability to affected populations (AAP). Each of these case studies provides a brief introduction and background about the humanitarian situation or emergency, an overview of the C4D response, and lessons learned and recommendations for future action. In addition, each one addresses relevant preparedness, response and recovery issues.
