Displacement is at a historic high, with over 65 million individuals currently displaced. The world is facing a refugee crisis that is unprecedented in scale. A large number of evaluations look at different aspects of programming in response to refugee crises in developing countries. This paper covers the key areas and priority topics related to forced displacement identified by the Development Assisstance Committee Temporary Working Group on Refugees and Migration. It draws from evaluation findings to highlight key lessons and recommendations for positive change going forward. Key topics covered in the paper include: lessons on bridging the gap between humanitarian and development programming; efforts to strengthen international response to protracted crises; lessons on whole-of-government approaches in refugee contexts; learning from work in urban settings; improving access to employment and quality education; new financing mechanisms for refugee crises in middle income countries; and lessons on financing in response to the Syria crisis. The paper highlights the evaluation work of DAC members and aims to help strengthen the evidence base to improve response to situations of displacement in developing countries.
