ETHNIC CONFLICT IN NIGERIA: CAUSES
AND SOLUTION
Nigerians are very sensitive when it comes to their ethnic
groups. An average Nigerian often sees his own tribe as
being superior to others. Ethnic conflicts are very
common and they bring about damage to lives and
properties. The key causes and solution to ethnic conflict
in Nigeria are discussed here.
Ethnic Conflict
CAUSES OF ETHNIC CONFLICT IN NIGERIA
TRIBALISM
Tribalism: Nigerians tend to segregate and discriminate
against people that are not from the same tribe. This
causes jealousy, hatred and can further cause conflict
between two or more ethnic groups.
INEQUALITY
Inequity: If it seems the Goverment favours one ethnic
group over the other in the allocation of resources, e.g
budget allocation. The concerned tribe would feel slighted
and show their protests by acts of violence, which may
result in ethnic conflict in Nigeria.
LAND DISPUTES
Land disputes: if it happens that two states have a
dispute over the ownership of a piece of land that serves
as a boundary, there is bound to be disagreement
between the two ethnic groups.
HISTORY
History: if two ethnic groups have had a long-standing
history of conflict between each other, such is bound to
continue even in the present.
IGNORANCE
Ignorance: Many individuals live in total ignorance about
other ethnic groups. They instead dwell on rumors of the
negative things about other tribal groups apart from theirs.
This would make them develop a hatred for other tribal
groups.
SOLUTIONS TO ETHNIC CONFLICT IN
NIGERIA
SENSITISATION
Sensitization: There should be workshops to sensitize
and create awareness to the general public on the need
for national unity and patriotism.
EQUITY
Equity: the Goverment should be careful enough to share
financial resources and otherwise, equally.
DIALOGUE
Dialogue: the two ethnic parties should employ the use of
dialogue to settle disputes.
Creation of Job opportunities
Creation of Job opportunities: there should be the
presence of an enabling environment to engage the
youths to avoid idleness. They should be adequately
trained on how to establish small and medium scale
enterprises.
INTEGRATION
Integration: platforms, where Nigerians get to learn more
about other ethnic groups, should be encouraged. This
would inculcate the spirit of unity and togetherness
among citizen
