LERRN, the Refugee Studies Centre (RSC) at the University of Oxford, and the Centre for Lebanese Studies (CLS), are working together on a study funded by a consortium of donors including the International Development Research Centre (IDRC), the Open Society Foundations (OSF), Robert Bosch Stiftung and others. This innovative, fully participatory research is led by researchers with lived experience of forced displacement and aims to understand the factors that influence the impact of refugee-led organisations (RLOs) as service-delivery providers in humanitarian settings in East Africa and the Middle East.
