Multiple Pressures On Africa's Third Longest
River continued
WWF
is eager to demonstrate the benefits to both food security and
biodiversity conservation from maintaining the characteristics of a
natural river and floodplain through small-scale polyculture rather
than through the highly water-consumptive, polluting and
dam-dependent strategies of irrigated agriculture. Following an
investigation last June and July, WWF has identified a range of
promising partners and projects that may be interwoven to support a
comprehensive strategy for the aquatic biodiversity of the River
Niger named the Living Niger River Initiative.
The aim is to create a basis for the sustainable use of natural
resources, to support biodiversity conservation and improve people's
living standards. The initiative will recognize and consider links
between the five global-200 ecoregions that are important to the
River Niger - namely the Guinean forests, Upper Guinea Rivers and
Streams, the Sud-Sahalian flooded grasslands of the Niger Inner
Delta in Mali, the Gulf of Guinea mangrove forests and the Niger
delta in Nigeria. The initiative hopes to develop a cooperative
relationship with the Niger Dams Authority and the Nigerian Niger
Basin Development Authority but, at the same time, to keep a clear
focus on biodiversity and threats upstream of Nigeria.
Failures Of Nigeria's Kainji Dam
The arguments in support of the construction of the Kainji dam
were electrical-power generation for all of Nigeria with enough over
for export to the Niger Republic, better water transport beyond
Lokoja, improved fisheries including a fish-canning industry, access
to adequate water for irrigated agriculture and the supply of
potable water to the resettlement villages. Potable water is
supplied sporadically to the housing estate of the Kainji dam
authorities. In the first 10 years of Lake Kainji's existence, there
was a fishing boom but it was short-lived because the boom attracted
migrant fishermen from other parts of Nigeria and by 1979 there was
evidence of overfishing in the lake. Fish stocks crashed, and the
migrant fishermen left. The fish-canning industry was not built. For
irrigated agriculture, the lake did supply adequate water but only
to irrigate marginal upland soils. Moreover, the people could not
afford the expensive irrigation equipment needed in these new
conditions. Control of water flow at the dam did not permit water
transport at all, not to mention getting to Lokoja. The aim of
supplying electricity, on the other hand, has not been realized. The
Kainji dam was designed to turn 12 electricity-generating turbines.
When the dam was closed in 1968, it was clear that at peak
performance it would barely turn eight turbines. At present it works
only four. Meanwhile, the fertile flood plains of the Niger with
their age-old tested livelihood system were lost. The sugarcane
farms downstream at Basita (which depended on the natural flooding
of the Niger) were devastated. The Basita Sugar Industry sought raw
materials elsewhere as sugarcane farmers sought new livelihoods. The
traditional dry-season grazing ground of the nomadic Fulani cattle
was lost, causing conflicts between the nomads and resident farmers.
People's health suffered because of the recurrent and hitherto
infrequent water-borne diseases. The coastal Niger delta was not
spared. Because of unpredictable flood patterns (which now depend on
erratic off-season releases from the dam), crops and property are
regularly lost. To address these problems, the Nigerian Government
set up the Kainji Lake Research Institute (now The National
Institute for Freshwater Fisheries Research) to investigate and
offer solutions to the socio-economic, health, fishery and wildlife
management problems associated with the creation of Lake Kainji, but
in 1983 another dam was built downstream of Kainji at Jebba
compounding the problems.
These and other dams and barrages in Niger Republic and in Mali
raised the need for a coordinated approach to the development of the
River Niger system. Benin, Burkina Faso, Chad, Cameroon, Cote
D'Ivoire, Guinea, Mali, Niger and Nigeria therefore formed the Niger
River Commission. The commission is more or less moribund, and
uncoordinated development of the Niger system still continues. To
the power generation authorities, water storage is vital for
livelihood. Their operations have led to significant changes in the
livelihood systems of the people, which have been translated into
increased pressure on resources and the resultant deforestation,
erosion, situation of the river and loss of biodiversity.
