ACE has been working to collate knowledge on the art (ccraft/experiential evidence) and the science (research evidence) on evidence-informed decision-making in Africa. We have started to carve out some pieces of work towards this end. In 2018, this included further collation of information on evidence ecosystems from across Africa. Following our successful evidence ecosystem mapping programme as part of Evidence 2016, we received an additional 16 evidence landscape maps as part of Evidence 2018 bursaries applications. In addition, we developed a geo-map of evidence-informed decision-making institutions in Africa to develop a database of the key role players on the continent.
