Dams and irrigated plantations being built in Ethiopia will bring major changes to the flow of the Lower Omo River, which in turn will harm ecosystem functions and local livelihoods all the way to the river's terminus at Lake Turkana in Kenya. More dams are planned for the basin that would compound the damages.
Here we outline some of the basic changes that can be expected as a result of these developments, and include resources on where to get more information.
The video below illustrates the hydrological risks the dam and plantations bring to the Lower Omo and Lake Turkana:
Climate change could worsen the water situation in the Omo. More extreme droughts and unpredictable precipitation patterns, combined with higher temperatures (which increase evaporation), could cause further stress to a region that already experiences extreme precipitation variability. There is evidence that there will be a drying trend and warmer temperatures.
The World Heritage Centre and IUCN have jointly decided to inscribe the Lake Turkana Parks heritage site into the List of World Heritage in Danger. This decision is awaiting approval by the World Heritage Committee during their 36th session at St. Petersburg, Russia, June 24 till July 6, 2012.
The decision is based on findings of the joint mission visit to Lake Turkana in March 2012 that identified the dangers posed by Gibe 3 Dam construction and associated irrigation fed plantations and dams in the Lower Omo basin, oil exploration, pressure from poaching and livestock grazing and impacts of other larger developments in northern Kenya. The joint team concludes that these dangers are severe enough to place the Lake Turkana heritage site in the danger list.
Gibe 3 Dam and associated irrigation plans is the biggest danger to the lake. Gibe 3, according to the official Ethiopian website for the project, is 50% complete and it will take 3 years to fill up once completed. During this 3-year period, the water levels on Lake Turkana will reduce by 1.65 to 4m above normal flactuation levels according to joint team's models. But this is not the biggest problem. According to the team's assessment:
After filling is complete and if no water would be extracted from the Omo river downstream of the dam, normal river flow volumes would return to the lake, but it could take 12 years for the lake to return to its equilibrium level. Thus the impact of filling may last 15 years in total. The drop in water levels will move the shoreline of the lake significantly, particularly in the northern part of the lake where two components of the property are located (estimated at 2-3 km minimum at a drop of 1.65 m). This significant drop in lake levels could result in increased salinity and in likely impacts on wildlife which depends on the riparian flood plains and wetland habitats along the lake’s shore for food and breeding as well as on fish stocks as a result of the drying out of major fish spawning areas, such as Ferguson’s Gulf and the delta of the Omo River)
There will also be direct impacts of reduced oscillation due to the dams flood control capacity. Cummulative irrigation projects in the Lower Omo will complicate this matter further. For instance "the Kuraz sugar development is already under construction and there are plans to convert 278,000 ha of land along the river to sugar plantations and other agricultural developments using irrigation. The African Development Bank study cites the Omo-Gibe basin master plan in which irrigation developments by 2024 would use 16% of the basin’s water and calculates this would lead to a reduction in lake level of 8.4 m. This is a significant hydrological change to the lake."
The World Heritage and IUCN team cites many other reasons for inscribing Lake Turkana into the danger list. You can read the section on Lake Turkana in their report which can be downloaded here. Lake Turkana is on page 11 of this PDF document.
In a new paper entitled "What future for lake Turkana: the impact of hydropower and irrigation development on the world’s largest desert lake", the Nairobi based hydrologist and consulting engineer, Dr Sean Avery, considers the impacts on the lake of river basin development in the Omo Valley. The paper is based on reports submitted by Dr Avery to the African Development Bank (2010) and to the African Studies Centre at Oxford University (2012).
What Future for Lake Turkana?
The Gibe III Dam, now being built in the middle basin of the Omo, will make possible large-scale commercial irrigation schemes in the lower basin. One of these schemes, now being implemented by the Ethiopian Sugar Corporation, will equal in extent the current irrigated area of Kenya. This will require a huge rate of water abstraction from the Omo, a transboundary river and the source of 90 per cent of Lake Turkana’s freshwater and accompanying nutrient inflow.

The actual irrigation water demand will depend not only on the crop area to be irrigated but also on the overall efficiency of the irrigation system. Making the optimistic assumption of an overall irrigation efficiency of 60 per cent, the paper predicts that the sugar scheme alone will require well over 30 per cent of the Omo flow. This rises to almost 40 per cent if the remaining area already allocated to irrigation development in the Lower Omo is included. If the efficiency assumption is reduced to 45 per cent (the figure used by the Omo-Gibe Master Plan of 1996) the total water demand for projected irrigation development in the Lower Omo reaches over 50 per cent.
This would lead to a drop in lake level of over 20 metres (its average depth is roughly 30 metres), a more than 50 per cent reduction in its volume and biomass (total mass of living organisms) and a drastic fall in the productivity of its fisheries. Ultimately, the lake could reduce to two small lakes, one fed by the Omo and the other by the Kerio and Turkwel rivers. The picture that emerges from these predictions bears a striking resemblance to the recent disastrous history of the Aral Sea, a non-outlet lake in Central Asia which was once the world’s fourth largest inland water body.

Kenya's Ikal Angelei has won one of this year's Goldman Prizes, often called the Nobel Prize for environmentalists. Ms Angelei mobilised her community in Turkana - northern Kenya - to try and stop a massive dam from being built in neighbouring Ethiopia. She realised that the projected Gibe-3 dam on Ethiopia's Omo River - which empties into Lake Turkana - could destroy the livelihoods of thousands of people. Ms Angelei told the BBC Africa's Audrey Brown why she kick-started a campaign to get the project stopped and what she and the group she co-ordinates, Friends of Lake Turkana, will do with the $150,000 (£94,600) from the prize.
Ikal was interviewed by the BBC and you can listen to the podcast at the BBC Website
Lake Turkana is the world’s largest “desert sea," a vast turquoise ocean in an unremittingly harsh place of wind, heat and dust.
Its waters keep the cattle of semi-nomadic pastoralists alive in times of drought and its fish feed the people.
It is one of the origins of mankind where, according to the fossil record, the earliest human ancestors rose up on two legs and began to walk, and it has been designated a UNESCO World Heritage Site.
Yet it is threatened with extinction by Africa’s largest hydroelectric dam which is already around three-quarters built and likely to be completed in 2014.
The Gilgel Gibe III Hydroelectric dam on the Omo River in southern Ethiopia will be 243 meters high. The project is expected to generate up to 1,860 megawatts of energy, and to supply enough water to irrigate 150,000 hectares of agricultural plantations.
The dam is key to the economic future that Ethiopia’s leaders have mapped out for their country. But experts say it will also destroy Lake Turkana just across the border in Kenya.
“The result could be another Aral Sea disaster in the making,” writes Sean Avery, a Nairobi-based hydrologist in a new report published by the Africa Studies Centre at the University of Oxford.
The Aral Sea in Central Asia was one of the world’s largest lakes until Soviet irrigation projects diverted the rivers that fed it, reducing the lake to a tiny fraction of its original size.
For its part, Lake Turkana is slightly salty and shallow.
Only 30 meters deep on average, Avery predicts water levels could fall by 20 meters, turning the lake into two separate, outsized puddles — one fed by the remnants of the Omo, the other by the smaller Kerio and Turkwel rivers.
Salinity levels are expected to rise as the surface area shrinks, making the lake unlivable for fish, hippos and crocodiles and undrinkable for cattle and people.
“Lake Turkana depends on the Omo River for 90 percent of its water,” said Ikal Angelei, director of Friends of Lake Turkana who was awarded the 2012 Goldman Prize in recognition of her efforts to save the lake and the livelihoods of the people who depend on it.
“If you reduce the freshwater coming in you change the chemical composition of the lake,” she told GlobalPost. Up to 300,000 people rely on the lake to survive, she added.
Ethiopia’s government says that once the Gibe III dam is filled up in two and a half years, a constant stream of water will be permitted to flow down the Omo valley and into Lake Turkana.
But Angelei said this will not solve the problem.
“It’s the natural increases and decreases in water flow that allows the ecosystem to survive,” she said.
Fish breeding cycles as well as seasonal farming on the river’s floodplains require times of high and low water.
“The regulation of the natural hydrological river flow cycle will permanently alter the present flood plain's ecology, with catastrophic consequences,” wrote Avery.
Avery’s report also stated that 30 percent of the Omo’s flow was to be diverted for the irrigation of huge new agricultural plantations.
Ethiopia’s government had kept the plantation plans secret until New York-based advocacy group Human Rights Watch revealed details of the scheme in a report published last year.
The rights group accused the Ethiopian government of “arbitrary arrests and detentions, beatings, and other violence” as it forced indigenous people off their lands to make way for state-run sugar plantations, irrigation canals and processing factories.
“Ethiopia’s ambitious plans for the Omo valley appear to ignore the rights of the people who live there,” said the report’s author, Ben Rawlence.
Angelei says the dam threatens people's rights in Turkana too. Kenya’s government has done nothing to defend them.
The governments of both countries have contentious relations with pastoralist people who are frequently derided as backward and uncivilized.
Their very existence is seen as an affront to the sophistication, modernity and forward-leaning economies that the centralized authorities in Addis Ababa and Nairobi seek to project.
The pastoralist people frequently carry guns and disdain the sedentary life of towns and cities, preferring to move with their animals through the wilds.
Despite the expected impact on its people, successive Kenyan governments have raised only muted objections to the dam.
A parliamentary resolution in August 2011 called for construction to be stopped.
But the resolution was not acted on and was then quietly shelved when, 11 months later, the World Bank provided a $684 million loan for the building of a 1,000 kilometer transmission line that will allow Kenya to benefit from the power generated.
Angelei and others hope the scenario they envisage is a worst-case projection, but fear it is also the most realistic.
“Lake Turkana is a [UNESCO] protected area but it’s not being protected. It’s a safe zone in drought periods, it supports fishermen and pastoralists, it has traditional and cultural value and is the cradle of mankind, but it is being ignored,” she said.

Beneath Turkana County, the land of burning sand, blistering heat, so many hungers, and untold human misery, lies oil deposits that could forever change Kenya's economic fortunes.
The question remains how big are the underground oil wells in volume, their commercial value, and years it will take before Kenya can have it flowing across its pipelines.
But as the country toasted to President Kibaki’s surprise announcement that an Anglo-Irish oil exploration firm, Tullow Oil Company, had struck the precious commodity that accounts for 25 per cent of the country’s import bill, another burning question lingered in the shadows... Read more...
Our Director, Ikal Angelei, has been announced as the 2012 Goldman Environmental Prize Reciepient for Africa in recognition of her tireless effort to save Lake Turkana from the dangers of the massive Gibe 3 Dam being constructed in Ethiopia’s Omo River.
In 2008, Ikal Angelei, who also works with renowned anthropologist and conservationist, Dr. Richard Leakey, learned from the distinguished Kenyan of the construction of what will become Africa’s largest dam along the Omo River in Ethiopia. Ikal immediately recognized that the dam would be the death of Lake Turkana and the end of the livelihoods of hundreds of thousands of impoverished and marginalized people in the Lower Omo Basin and Lake Turkana regions.
Ikal started her campaign to stop the construction of the dam which had started in 2006. Shortly, she and likeminded individuals formed the Friends of Lake Turkana. FoLT thus became the vehicle that would spearhead the campaign to stop Gibe 3 on its tracks. In the few years that Ikal and FoLT have campaigned against the dam, we have managed to convince several financing organizations, including the World Bank, the European Investment Bank and the African Development Bank not to fund the construction of Gibe 3 – which is 40% complete – and convinced the UNESCO World Heritage Committee to issue a communiqué calling for a stop in the construction of Gibe 3. The Kenyan Parliament also passed a resolution requiring the government to demand an independent environmental Impact Assessment of the dam.
Ikal continues to trudge on as she is now pushing for the Kenyan government – which is in agreement with Ethiopia to purchase 60% of the electricity generated by the dam – to get out of the power purchase agreement thus make it unjustifiable for China to continue funding the dam owing to the diminished demand. As Ikal always says, “Aluta continua.”
The Goldman Environmental Prize was created in 1989 by civic leaders and philanthropist Richard N. Goldman and his wife Rhoda H. Goldman to support individuals struggling to win environmental victories against the odds. It is meant to inspire ordinary people to take extraordinary actions to protect the world. The phenomenal Prof. Wangari Maathai – RIP – won this Prize in 1991.

In an unfortunate twist, the World Heritage Committee has rejected recommendations by the International Union for the Conservation of Nature (IUCN) and the World Heritage Centre to inscribe the Lake Turkana National Parks into the list of World Heritage in Danger.
During their 36th meeting at St. Petersberg in Russia, the World Heritage Committee turned down the recommendation to inscribe the Lake and 3 other Heritage Sites into this list despite the looming doom that is to come from the building of Gibe 3 Dam in Ethiopia together with other developments in Kenya and Ethiopia. The IUCN expressed great disappointment following this decision.
"We are disappointed that the committee has not inscribed any of these threatened sites on the List of World Heritage in Danger this year," said Tim Badman, director of IUCN's World Heritage Programme, referring to Kenya’s Lake Turkana, Cameroon’s Dja Biosphere Reserve, Russia’s Virgin Komi Forests and the Pitons Management Area in the Caribbean island nation of Saint Lucia.
Ikal Angelei, activist and founder of the Friends of Lake Turkana, who have been fighting to save the lake and its people, also expressed great dissatisfaction saying, “It is a sad day for Lake Turkana and our people,” and adding that the inscription of the lake’s parks would have given it the prominence it desperately needs to survive the unrelenting onslaught of bad developments. "It must take a lot for UNESCO to consider a place to be in danger if Turkana did not make the list!" said Ms. Angelei. Ms. Angelei won the 2012 Goldman Environmental Prize for Africa earlier this year in recognition of her efforts to save Lake Turkana.
The IUCN decision to propose the lake into the World Heritage in Danger list was based on findings of the joint mission visit to Lake Turkana by the IUCN and the World Heritage Centre in March 2012 that identified the dangers posed by Gibe 3 Dam construction and associated irrigation fed plantations and dams in the Lower Omo basin, oil exploration, pressure from poaching and livestock grazing and impacts of other large developments in northern Kenya.
The Friends of Lake Turkana have been campaigning against Gibe 3 Dam and in the few years they’ve been doing so, they have managed to stop the African Development Bank from funding the Gibe III Dam in spite of strong Ethiopian pressure. The World Bank and the European Investment Bank also walked away recognizing that the project would violate their social and environmental safeguard policies. Other big would be financiers have also been convinced to withdraw their funding for the now half complete dam delaying the $1.7 billion project by several years.
The joint team concluded that these dangers are severe enough to place the Lake Turkana heritage site in the danger list. "These four sites face significant threats to their values, from threats including major infrastructure projects, the extractive industry and property speculation," said Badman. The World Heritage Committee ignored these arguments and failed to inscribe the precious property.
The 36th meeting of the committee started in June 24 and ends on July 6 this year. This is the second year in a row that the committee has rejected the inscription of the Russian property, the Virgin Komi Forests, into the list. It is still unclear why the committee rejected the proposed decisions to accord these important resources that additional protection.
A new study conducted by Dr Sean Avery and released by the African Study Centre reveals a much grimmer picture of the impact of the building of Gibe III Dam on the Omo River and associated large scale irrigation-dependent plantations in Ethiopia would have on the Lake Turkana and Lower Omo Basins. The report shows how Gibe's regulation of the flow of the Omo will alter the annual flood regime upon which the agro-pastoralists of the lower Omo depend for their livelihoods and how it will, coupled with the abstraction of Omo water for large-scale irrigation will alter the hydrological inflow patterns to Lake Turkana, directly impacting the ecology of the world's largest lake.
This is the second comprehensive study of the impact of Gibe on the hydrology of Lake Turkana and Lover Omo that the Nairobi-based consultant hydrologist and civil engineer, Dr Sean Avery, has conducted. Dr Avery previously carried out the only comprehensive assessment of the impact of the dam on Lake Turkana and Lower Omo - commissioned by the African Development Bank (AfDB) - but that was before the full scale of planned irrigation-dependent large scale plantation development was known.
A few months after the AFDB report was submitted, the full extent of planned irrigation development in the lower Omo became clearer, with the announcement that the state-run Ethiopian Sugar Corporation would soon begin developing 150,000 hectares of irrigated sugar plantations. It became necessary to conduct a new study to consolidate the previous findings with the new information.
Dr Avery's new report is now available to download from the website of the University of Oxford's African Studies Centre. We have placed the links to the two volume report and an executive summary here. You can also read Dr Avery's first report in the Documents Downloads section of our website.

A company associated with a Cabinet minister sold the block, where oil was found in Turkana, for a fortune.
In 2010, Turkana Drilling Company, associated with the Cabinet minister who was affected in Monday’s reshuffle, sold Block 10BB for $10 million (Sh840 million) to Africa Oil.
Turkana Drilling’s case is just an example of how small firms might be using influence in government to make hundreds of millions of shillings by trading in oil prospecting licences.
The whole business of acquiring blocks has been invaded by influence peddlers and well-connected middlemen, including Cabinet ministers. Watch the video below and go to Daily Nation website to Read More
