New dam in Mali will
cause starvation and destroy ancient city
The government of the
West African nation of Mali has announced that it is to press ahead with a
controversial new dam project, despite revelations that it will cause starvation
and threatens a 2,000 year-old city.
According to the US-based
NGO, Cultural Survival, even backers of the multimillion dollar Talo Dam, the
African Development Bank, on the River Bani, a tributary of the Niger, have
concerns about the project, which the Malian government, a major stakeholder in
Talo, is eager to start as soon as possible. “According to information we
received from the Associated Press bureau chief in West Africa, only last week
the Malian government reaffirmed its commitment to begin work on the dam soon,
despite a large demonstration by Djenné residents last weekend,” Cultural
Survival’s Director, Dr. Ian McIntosh, told edie. “We have had
meetings with executives from the African Development Bank, and they agree that
the environmental impact assessment was flawed, and that the dam will have a
negative impact on up to one million people downstream,” McIntosh said. “The
dam will have a devastating effect on the environment, 40,000 will face famine
in the first year and the town of Djenné will be deserted.”
The dam is being
constructed to raise the level of the Bani River, upstream of the ancient city
of Djenné, sufficiently to feed irrigation networks covering regions that only
20-30 years ago lay in the flood plain of this arid subsistence nation and
produced food. Although an environmental impact assessment (EIA) was carried
out, it only covered upstream areas and no mention was made of possible effects
downstream, which citizens of Djenné and many other towns as far away as the
border with Burkina Faso, Cultural Survival and the African Development Bank,
are concerned about.
The principal fears are
over possible starvation and loss of valuable subsistence crops as far away as
Burkina Faso. Cultural Survival commissioned a report by a team from the
International Development Office at Clark University in Worcester,
Massachusetts, which said that downstream residents of Djenné may be more
susceptible to drought. If the Bani had an ample supply, water sufficient to
meet the needs of downstream farmers could be released during dry season,
however as the Talo Dam, is proposed precisely because of the Bani’s dwindling
water supply, the proposed sluice gate is unlikely to help at the height of the
dry season. Although the African Development Bank states that only 6% of the
Bani River will be diverted annually for irrigation in the target area, Cultural
Survival’s hydrological analysis found up to 20% of the river will be diverted
while the reservoir is filling during the rainy season.
The project documents
fail to adequately consider ecological and systemic impacts, says Cultural
Survival. Fish populations may decline, resulting in a loss of livelihood for
the region’s many fishermen as life cycles of fish in the Bani River are
dependent on seasonal flooding. Farmers also use seasonal wetlands, especially
as surrounding rangelands dry out and controlled flooding cannot simulate the
natural floodplain’s quantity or distribution. Nomadic populations already
travel great distances to graze cattle in the delta and their rangelands will
become more arid as the Niger Inland Delta floodplain, which between 500,000 and
one million people depend on, shrinks, says the report. A reduction in
groundwater levels is also expected as the Talo Dam could further deplete
aquifers and the health of the populations in Djenné and surrounding villages
may deteriorate as irrigated wetland areas and stagnant reservoir water create
ideal breeding grounds for organisms responsible for the spread of malaria,
schistosomiasis, and bilharzias.
There is also widespread
concern over the future of the United Nations World Heritage Site the city of
Djenné, inhabited since 250 BC, home of the Djenné mosque - the world’s
largest adobe structure and almost 2,000 traditional houses, and one of Mali’s
top three tourist sites. The report says that a dam at Talo could potentially
result in the displacement of 20,000 residents of Djenné and the destruction of
the life of the city.
Cultural Survival
believes that before any dam can be built the following need to be fulfilled:
-
an
environmental impact assessment and socio-economic study focusing on
the downstream area (from the dam to Mopti);
-
an
environmental impact assessment focusing on potential effects of the
Talo Dam on the greater Niger Inland Delta;
-
a revised
cost-benefit analysis of potential losses that includes both
downstream and upstream costs or losses, in addition to projected
project benefits; and
-
a
comprehensive hydrological study taking into account the amount of
water to be diverted from the Bani River, including losses due to
factors such as evaporation, and considering climatic variability
instead of solely relying on yearly averages
