Abstract
The construction of dams has become a common feature of development
in many developing countries. It involves the building of
a barrier across a stream, river or lake, to hold back water for
single or multiple purposes. Such dams always creates positive and
negative physical and socio-economic impacts on their upstream and
downstream areas.
Jebba Dam, was constructed mainly to complement Kainji Dam in
generating electricity for the country's growing industrial and
domestic demands. In the process of its operation, the obvious impact
created on the spatial organisation upstream, was the displacement
of 6,111 people in 42 villages, by the reservoir. Being a forseen
impact, however, adequate arrangements were made by NEPA for the
resettlement, though it attained only little success due to lack of
effective and efficient management of the exercise.
In the downstream areas of the dam, impacts have been created
on the spatial organisation and the economy of the people. This is
because, with the regulation of flow downstream, the floodplains
formerly liable to flood annually, became permanently exposed. This
in turn enhanced the development of agriculture and the spatial organisation
of the areas.
This regulation of flow, on the other hand, also reduced the
river regime downstream so much that navigation became difficult.
Finally, with the creation of the dam, sedimentation of the
river downstream had declined so much that fishing had declined
drastically in the area. All these impacts, some of which are in
form of problems, prevailing in the downstream area today, have
vii
received no attention from the National Electric Power Authority
or any other agency. This study therefore argues that, dam constru®-
tion should always be seen as a multi-purpose programme, whereby the
authority in charge oversees the impacts created in both the upstream
and downstream areas of the dam, for an effective and unitary river
basin development. This is demonstrated in the proposals made for
the downstream areas of Jebba Dam.
