Refugee-led organisations (RLOs) in East Africa play a vital role in meeting community needs. To date, however, there is a lack of rigorous evidence on the impact of RLO responses on displaced communities, how RLOs are perceived by the communities in which they operate, and what factors condition the variation in response and impact of RLOs. This study, led by Carleton University’s Local Engagement Refugee Research Network (LERRN) and the Refugee-Led Research Hub (RLRH) at the University of Oxford, seeks to fill this gap in 11 urban and camp/settlement sites across Ethiopia, Kenya, Tanzania, and Uganda. A team of researchers affected by displacement led the study from start to finish and implemented two phases of data collection between May 2021 and June 2022.
