The Ogun river cuts
across the south-western Nigerian states of Ondo, Osun, Oyo,
Ogun and Lagos before bursting into the Atlantic Ocean through
the republic of Benin. Ogun State derived its name from this
river.
Ogun River is of immense
importance geologically, biologically, historically and culturally.
The river provides habitat, nourishment and means of transport
to countless organisms. The river provides travel routes for
exploration, commerce and recreation. The river leaves valuable
deposits of sediments such as sand and gravel along the banks
on its way to the ocean. Ogun River is a source of domestic
water which supports the populations that have settled on
either side of the river’s course.

However, for a river
from which Ogun State derived its name the river is not being
well treated - the river is poorly maintained and faeces and
domestic wastes are regularly emptied along its banks leaving
the river polluted.
In a field study conducted
in 2007 water samples were collected from thirteen different
sites along Ogun River and analysed for physio-chemical and
bacteriological parameters as well as heavy metals using standard
methods. Generally, the values obtained for turbidity, phosphate,
oil and grease, iron and faecal coliform from all the sites
over a year were above the maximum acceptable limit set by
the World Health Organisation (WHO) for drinking water. This
pollution of the river water along its course evidenced by
the high concentrates of pollution indicators, nutrients and
trace metals above the acceptable limit poses a health risk
to the several rural communities who rely on the river primarily
as their source of domestic water.
Ogun River is underdeveloped.
The river is not navigable by sizeable inland water vehicles.
This is sad because considering that the river has access
to the sea and passes through five south-western states of
Nigeria, if developed the river would provide a cheap alternative
means of transport thus easing the current over-dependence
on the over-burdened road networks. This river development
however, would be a huge project if the Ogun River Basin States
decided to develop the river. They would need to dredge the
river and also carry out various environmental impact assessments
among other tasks. The project would require them to invest
huge amounts of capital and involve foreign as well as local
expertise to carry it out. Carrying out projects of this magnitude
however is not something we are good at in Nigeria. With the
required dedication and commitment though it can be carried
out and indeed should be carried out considering the benefits
that can be derived from a developed Ogun River.

A developed and navigable
Ogun River will allow inland water boats and barges to transport
people and goods up and down the river greatly boosting commerce.
The river will also be able to support recreation and tourism
which can bring in revenue to the Ogun River Basin States.
One of the sites along the tour would be the historic Olumo
Rock in Abeokuta.
The developed river would
also have to be well maintained and treated for pollution
to improve the source of domestic water for rural communities
along the river. The river could also provide water for irrigation
to support and improve agricultural production in south-west
Nigeria.
Around the world examples
abound of rivers that are of social, political, economic and
recreational importance to their societies. These rivers are
also popular tourist destinations. These rivers include the
Nile of Egypt, Thames of England and Mississippi of the United
States.
The Nigerian government
has a vision 2020 goal of turning Nigeria into a developed
economy by the year 2020. For this vision to come true regional
projects like the development of the Ogun River Basin must
be implemented successfully. |
