Prime Witness Change and Policy Challenges in Buhari's Nigeria is essentially a product of the author's observations, exchanges with his various interlocutors in and out of government, and Nigerians and non-Nigerians alike, during the first year of the Buhari administration, 2015-2016. The decision to put this volume together, and indeed, the compelling reason for articulating the policy recommendations, critiques and views herein, derived in his personal belief that as a member of the Nigerian attentive public, we owed it as a civic duty to our posterity to speak up, regardless of whether anyone is listening. Such undertaking will no doubt, enrich our national conversation of critical issues and in the long run, vindicate us in the eyes of our posterity.
