LOYANGALANI, Kenya - The fishermen and herders eking out an existence on the
shores of the majestic Lake Turkana risk having their way of life destroyed
by a giant dam under construction in Ethiopia, their neighbour to the north.
Glittering jade under the scorching sun, Lake Turkana is a fragile jewel in
an arid environment already hit by global warming. At 250 kilometres (150
miles) long by 60 kilometres wide at its largest point, it is the world's
biggest desert lake.
"This is a precious lake, an amazingly beautiful one and maybe in 60 years
from now you will not see the people here, nor the fish. and you will have a
dead lake," Joseph Lekuton, a local legislator, warns.
Flowing down from the north, the river Omo supplies Lake Turkana with 80
percent of its water. Since 2006, Ethiopia has been building a dam several
hundreds of kilometres upstream that will on completion be Africa's highest.
The 243-metre-high Gibe III dam will create a reservoir covering 210 square
kilometres (80 square miles).
In 2006 Kenya, which struggles to cover its energy needs, signed an
agreement with Ethiopia to import up to 500 MW produced by the dam.
For the people living around Lake Turkana that was seen as an act of
betrayal.
UNESCO -- which classes part of the lake as a World Heritage site --
condemned the Ethiopian dam project.
China stepped in to finance the project and around 50 percent of the dam has
already been built.
Crusading environmentalist Ikal Angelei, who founded the Friends of Lake
Turkana pressure group in 2008, estimates that water levels in the lake will
go down by two to five metres as the dam's reservoir fills up and will never
return to normal.
"We are really definitely duplicating the Aral sea (devastated since the
1960s when water was pumped out to grow cotton) -- building a dam and now
putting sugarcane and cotton plantations downstream in the Omo basin, all
things that will reduce the amount of water flowing into the lake," Angelei
said.
The surface area of the lake has already shrunk by dozens of metres over the
past few years as rising temperatures have led to increased evaporation.
That is in a region where temperatures already climb to over 40 degrees
Celsius (104 degrees Fahrenheit) for most of the year.
Fighting between communities for control of watering holes for livestock and
grazing land has become more common as water has become scarcer and a year
ago Turkana was the area of Kenya hit hardest by the drought and famine that
struck East Africa.
"We have adapted to the changes over the years and we have built a sense of
resilience but now we have reached a tipping point," said Angelei, who
earlier this year won the prestigious Goldman prize -- considered a sort of
Nobel prize for environmentalists.
"Should we have an abrupt change, it is really scary to think what could
happen," she went on, raising the spectre of local people becoming dependent
on food aid or being herded into displaced camps.
Lake Turkana is "a very fragile ecosystem", and data on the dam's potential
impact has been limited, according to Achim Steiner, executive director for
the Nairobi-based United Nations Environment Programme.
"There is a reason to be concerned [because] the environmental assessment,
the hydrological data, the models have not been as public as perhaps some
would have wished them to be," Steiner said.
"If at the end the result of the dam being constructed and operated is that
the ecosystem can no longer function the way it had over hundreds or
thousands of years, then clearly you have a major disruption, and neither
the Kenyan nor the Ethiopian authorities would like it to happen," Steiner
said.
"But these things need to be studied, discussed and assessed in advance, not
after the fact."
Meanwhile, some activists are already resigned to the fact that the dam will
be finished and are already looking ahead to what can be done next.
"To be very honest it is only a matter of time before the Chinese release
the money to complete the dam... so our next plan of action is to develop
something akin to the Nile water basin whereby we would have a stake in what
happens upstream," said Gideon Lepalo, director of the Save Lake Turkana
Campaign project.
"I have very good memories of the lake as a child," he said, adding that it
pained him that his children would not have similar memories to hold on to.
