This edited volume transcends conventional state-centric and formalistic notions of regionalism and theorizes, conceptualizes and analyzes the complexities and contradictions of regionalization processes in contemporary Africa. The collection not only unpacks and theorizes the African state-society complex with regard to new regionalism, but also explicitly integrates the often neglected discourse of human security and human development. In so doing, the book moves the discussion of new regionalism forward at the same time as it adds important insights to security and development. It is organized into three parts. Part I theorizes, conceptualizes and analyzes the new regionalism in Africa from the point of view of the region (e.g. West, East, Central and Southern Africa). The national perspectives in Part II focus on the new regionalism in Africa from the point of view of particular countries or specific state-society complexes, such as Kenya, the Democratic Republic of the Congo (DRC), the enclave of Cabinda, Angola and Zambia. Part III contains two concluding chapters that tie the main threads of the volume together, theoretically and empirically, and discuss the contribution of the analytical framework, the new regionalism approach (NRA) to the larger study of regionalism.
