Agricultural policymakers in Africaincreasingly face the need for policy options based onevidence-based analysis to promote agriculturaltransformation and to adapt to climate change. Furthermore,data and analytical tools to support informed agriculturalpolicymaking are increasingly abundant thanks to investmentin these areas, mostly from external sources. Still, the useof hard data and robust analyses linked to outcomes arestill rare in most agricultural policymaking in the region.Today, ministries of agriculture (MoAs) are increasinglyunder pressure to show ministries of economy and finance(MoEFs) both the rationale behind spending and the impact ofpast spending, particularly net estimated impacts on forexand fiscal balances. Even so, at present most Africangovernments are still under-spending on agricultural publicgoods such as research, extension, and infrastructure. Thepresent paper focuses on what can be learned to improveoutcomes from experiences promoting the increased use ofevidence in agricultural policymaking.
