The prevalence of intra-state conflicts and state failures in Africa since the end of the Cold War has made Africa the epicentre of threats to human, national and international security. The inability of African states to combat the insecurities in their respective countries reinforces the discourse on the role of the African Union (AU) in enhancing peace and security across the continent. Since its establishment in 2002, the AU has responded to some security challenges in Africa. In situations of armed conflicts, especially where diplomatic and mediatory efforts fail, the AU has adopted military interventionist mechanisms to protect civilians and to restore peace and security in accord with Article 4(h) of the AU Constitutive Act. Drawing from the cases of Somalia, Sudan and Libya, this research evaluates the capacity of the AU to operationalize the idea of ‘African Solutions to African Problems’ and enforce peace and security especially through its military interventionist mechanisms. Limitations in terms of resources, expertise and funds as well as the poor commitment of member states constitute setbacks to the AU’s effort at conflict management. For the AU to perform effectively in conflict situations, it is imperative for the regional body to develop the required supranational capacity to compel obedience from member states as well as warring parties. / Thesis (M.Soc.Sc.)-University of KwaZulu-Natal, Pietermaritzburg, 2014.
