The study focuses on the problem of peacemaking processes in Africa in the quest for sustainable development. Peace making processes employed in the African societies have not yielded lasting solutions. In most cases, they have compounded the multifaceted and deep-seated causes of the social conflicts and wars, which disrupt peaceful coexistence and vitiate the potential for sustainable development. This shortcoming has compelled more careful theoretical analyses of the sources of the social conflicts and wars with the adequate epistemic approaches. With critical analyses, the essay presents the epistemic foundations of hermeneutical approach, phenomenological positions, dialectical analysis and pragmatic experimentalism as the basic theoretical models for the analyses of the sources of social conflicts and wars in the peacemaking processes. It highlights the need for the fundamental peacemaking processes based on the full articulation of those crucial concepts and epistemic approaches. It examines the context of peacemaking in Africa and the part to reconciliation and restoration of peace, social order and national integration. Its major contribution lies in the explicit quests for more viable and enduring peacemaking approaches that would ensure social order and sustainable development.
