The problem in Africa, South of the Sahara was not only that countries with a kind of thin or shoestring budget grappled to indebt themselves with loans to build, train and equip their security sector but also that security was wholly perceived to mean the protection of National Boarders and its resources, signing of military accords and treaties thereby casting internal security away from crucial concerns. The problems and contradictions imposed by this conundrum of the parochial conception of Security architecture and operatives have combined with an array of poor governance to beg for reform wherein state governance and Human security must be seen as crucially interdependent. It is with this preoccupation that the UN, EU, and AU have undertaken lasting measures to reform the security sector placing human security and good governance at the centrality of its hub. If this has been urgent in other areas of the world, the need is crucially acute in the Central African Sub Region whose member states have been encompassed not only by issues of fragile states borne out of problematic governance as well as transnational crime, secessionists claim and arm uprising as well as a transnational crime. This is the Nexus underlying good governance and the Security Sector reform which is the Substance of this study. From a thorough review of primary and secondary sources, the study seeks to – provide the special context and circumstances underlying Good governance and its connection to Security Sector Reform in the Central African Sub Region- Bring out the cogent elements of good governance and connect how this is crucial in the Security Sector Reform – Cast a Scientific focus on Good governance within the Security Sector using key Central African Region states and showcasing how this is important in state and peacebuilding as offered by the UN and its corollaries.
