This paper examined the role of governance on trans-border migration by Nigerian youths,
otherwise known, in local parlance, as Japa syndrome, and the implications of the attendant
human capital flight on Nigeria's national development. It deployed a combination of
theoretical modes and relied on trend data in explaining the causes and consequences of
human capital flight on the country's development. It argued that notwithstanding the
internationalization of train-border migration, the Third World nations, particularly Africa,
remain the end losers as the world’s migration trend represents a zero-sum matrix wherein
the ‘brain’ lost by the latter represents a proportionate ‘brain’ gained by the receiving
developed countries. It emphasized that if remittances are the major benefits of migration,
from the point of view of the source countries, the loss of human resources – particularly
highly skilled youths – is the most serious cost. It concludes that the net effect of youths'
migration poses greater danger to Nigeria’s developmental project; and that the efforts by
the governments to check brain drain as well as lure Nigerians in Diaspora back home
through advocacy programmes and policy propositions have come to naught, especially in
view of the obvious exacerbation of the prevailing socio-political and economic scenarios
which necessitated their exit.
