Refugee crises globally are not only increasing in scale but are also protracted and have significant development consequences. According to the Office of the United Nations High Commissioner for Refugees (UNHCR), currently more than 79.5 million people are displaced worldwide—the highest number on record. As the Syrian crisis has entered its tenth year, this assessment of UNDP support to the Syrian refugee crisis response and promoting an integrated resilience approach is especially timely. The evaluation covers the Syrian refugee crisis-response programmes in Turkey, Lebanon, Jordan, Iraq and Egypt for the period 2015-2019. The evaluation assessed the coordination structure of the Regional Refugee Response Plan (3RP) and key streams of the UNDP country-level response.
