In 2009, the Bill & Melinda Gates Foundation created the ARISE project, managed by JSI, to assemble the evidence on what drives improvements in RI performance in Africa. To amass such evidence, ARISE conducted in-depth, mixed methods comparative case studies in Cameroon, Ethiopia, and Ghana. It employed an assets-based approach to identify common drivers of improvements in RI performance at the district level, describe the pathways by which they improve coverage, and identify contextual factors affecting performance.
