Book excerpt: Based on Africa's deep routed structural problems, the key aspect of a transformative regional integration is how to promote structural transformation by adapted strategies and policies for the African regional economic communities, for the Continental Free Trade Area, and for the Tripartite Free Trade Area. Regional integration in Africa is based on a conventional (linear) model, starting with trade preference zones and moving to free trade areas, customs unions, and monetary and economic zones, with the ultimate goal to reach political unity. Specific problems of a more transformative regional integration agenda are discussed, such as: ?food security and agriculture; industry development, enterprise growth and competition; and economic partnership agreements with extra-regional partners. In the final section, the impact of three global value chains of importance for Africa (diamonds, shea butter, and sesame) are considered on regions, on sub-regions, and on regional integration.
