There is little controversy surrounding the role of civil society organizations in peace-building. Several researches have been done to identify the specific functions of CSO's in peace-building. Even though, increasingly, civil society and peace-building have received significant research attention from academics, policy-makers and practitioners, there exist a gap in testing how civil society organizations ensure social cohesion in societies dominated by ethnic politics. It is on the basis of this gap, that I seek to employ qualitative research methods to investigate further into the role of CSO's in peace-building with reference to ten West African countries. One main characteristic of these countries is, they have been largely polarised by ethnic party politics hence leaving doubt on the neutrality and credibility of CSO's to play a meaningful role in peace-building. Throughout the research work, various validation workshops and presentations will be done in the respective countries to relevant actors for a feedback.
