This paper focused on human capital flight and its multiplier effects on economic growth of Nigeria. Human Capital flight or brain drain is concerned with the movement of trained, competent personnel and professionals Africans most especially Nigeria have been leaving in droves. The cross roads between better offers and opportunities in distant lands of the West, Canada and the United States of America amongst others and the inherent problems hampering the full utilization of the potentials of professionals are examined in this paper. The paper further examines salient literatures on the trends and movement patterns of human capital as well as the factors which promote migration which have made Africa to remain poor, less developed and isolated as witnessed during the slave trade. The study therefore recommends among others that government should adopt appropriate policies to discourage human capital flight in order to encourage professionals to stay back in their countries and work towards economic growth. Also, to formulate workable
government policy on environmental sustainability and development that could promote conducive working environment that will bring about efficiency of labour as well as high level of productivity. Finally the paper concludes that appropriate investment in education and human capital development which will in turn discourage human capital flight must be pursued by developing nations especially
Nigeria.
