The Yearbook on the African Union is first and foremost an academic project that will provide in-depth evaluation and analysis of the institution, its processes, and its engagements. Despite the increased agency in recent years of the African Union in general, and the African Union Commission in particular, little is known – outside expert policy or niche academic circles – about the Union’s activities. This is the gap this book wants to systematically address. It seeks to be a reference point for in-depth research, evidence-based policy-making and decision-making.
