Dam rupture dam in Brazilian town - Americas - Al Jazeera English




Brazil's Rio de Janeiro state has placed emergency teams on maximum alert as heavy rains that have displaced 35,000 residents were forecast to continue, reviving fears of mudslides and flooding that killed about 900 people early last year.

Residents scrambled to gather their belongings and flee in the Tres Vendas district of Campos de Goytacazes in the north of the state, after a small dam ruptured, sending water rushing through the streets.

Meanwhile, local media reported eight people had died by Thursday after floods in neighbouring Minas Gerais state, with 87 towns there declared a states of emergency.

A pensioner was also reported to have been killed while trying to save personal belongings in one flooded town in northeastern Rio de Janeiro.

Emergency workers said more than 1,000 families from Tres Vendas had been evacuated to shelters.

"We're trying to put up stone barriers to prevent the water advancing but it's difficult," Rosinha Garotinho, prefect of Campos and a former state governor, said.


Flooding killed 900 people and destroyed more than 31,000 homes in Brazil in early 2011

She said there was no immediate risk of flooding in other districts of Campos.

Rio governor Sergio Cabral said the maximum alert, which requires emergency teams to intensify preparations, was focused on vulnerable towns in the north and northeast of the state as well as the Serrana region 97km north of the capital.

A year ago, heavy rain caused mudslides in the Serrana region that killed around 900 people, many of whom were asleep when rivers of mud buried them in their homes.

Photographs of the ruptured dam in Tres Vendas showed muddy water rushing through a gap in the dam about the width of three cars.

"Now, about 40 per cent of the streets [of Tres Vendas] are engulfed in water and we expect it will reach them all," said Major Edison Pessanha of the Civil Defence authority, according to a local government website.

Campos de Goytacazes, located about 280km north of Rio de Janeiro, is adjacent to the offshore Campos Basin from where about 80 per cent of Brazil's oil is pumped.


Grand Ethiopian Renaissance Dam: Egypt’s enemy or a blessing in disguise? | Al-Masry Al-Youm: Today's News from Egypt

Ethiopias Millennium damPreliminary construction of the Grand Ethiopian Renaissance Dam (GRD) began in April 2011 on the Blue Nile River near the Sudanese border. Scheduled for completion in 2014, it is planned to be the biggest hydropower dam in Africa, with more than twice the generating capacity of the Aswan High Dam. But long before the completion date, the project is already generating significant concern amongst the nine other countries that share the Nile, especially Egypt.
Over the past century many treaties have been signed in an attempt to assure each riparian country a right to Nile water, with Egypt generally receiving the lion’s share. But sub-Saharan African counties have long argued that the old treaties deny their modern right to livelihood, and after a decade of political to-and-fro between these countries and Egypt, the GRD is now underway.
Most recently, the Egyptian government protested that no quantitative studies have been conducted with regard to the dam’s effects, a complaint that resulted in a trilateral ministerial meeting being held in November between Ethiopia, Egypt and Sudan. During this meeting, it was announced that an independent technical committee of experts from each country would be formed in six months time to produce such a study.
But at the same meeting, Alemayehu Tegenu, the Ethiopian minister of water and energy, declared that regardless of the study’s outcome, the construction of the dam will continue unabated due to high confidence that the GRD will ultimately benefit all parties.
Adel Darwish, a British journalist and historian who co-wrote the 1994 book “Water Wars: Coming Conflicts in the Middle East,” told Egypt Independent that Egypt never should have ruled out the option of military intervention, because the stakes are so high for the country’s livelihood.
While Egypt Waits
Various experts have recently shared with Egypt Independent their own input on the potential pros and cons of the GRD.
Sherine al-Baradei, an AUC professor in the department of construction and architectural engineering with a focus on hydraulics, points out a number of major issues with the dam.
“Obviously, dams provide both good and bad effects,” she says. “But with Egypt being so dependent on the Nile, serious agreements must be made to ensure that the bad effects are minimized, and in advance.”
According to Baradei, hydropower dams create immense turbulence in the water, where chemical reactions such as dissolved oxygen can destroy fauna and flora. While the water will return to its normal state before reaching Egypt, the damage to these populations will be permanent. In addition, many nutrients and silt, which are essential for agriculture, will be retained in the large dam.
“When the Aswan High Dam was built, farmers, fisheries and many others were seriously affected for decades by the lowering of nutrients, silt, flora and fauna in the water,” she says.
Baradei explains that these levels will certainly drop further with the GRD, not to mention many other unforeseen problems that will likely occur.
Perhaps the most significant concern is that Egypt may no longer receive its appropriate share of water. But according to Baradei, issues of water regulation can be solved through negotiations with Ethiopia, whereas there is no solution for the loss of flora and fauna.
The Nile Basin Core Group (NBCG), a team of Nile specialists, has a more positive analysis of the situation. In their view, the GRD is an opportunity to create strong ties between Egypt and sub-Saharan countries, and there may also be many positive effects of the dam.
“The right question is not what the effects of the GRD will be, but how the Nile basin’s water can be used to integrate all riparian countries in a stable and efficient way,” says Mohamed al-Mongy, an environmental development specialist from the NBCG. “Instead of looking North, East and West for our solutions, we need to begin looking South, where the source of our livelihood lies.”
One of Mongy’s colleagues at NBCG, Haytham Awad, a hydrologist from the University of Alexandria, has conducted research that indicates the GRD may actually increase water flow to Egypt.
Awad’s research shows that during the flood season in late August and early September, the majority of Egypt’s water arrives in Lake Nasser, where it is stored for approximately ten months until peak agriculture season in July the following year. During this period, approximately twelve percent of the stored water evaporates.
However, with the water being stored in the GRD, where there will be less evaporation and that will help conserve water.
Another finding is that the GRD is expected to produce power surpluses which, assuming cooperation, could be exported to Egypt, leading to strengthened ties between the two countries.
“Collaboration is key,” says Lama El Hatow, a member of the NBCG doing her PhD research on water governance of the Nile basin. “When we negotiate with the riparian states, it is vital that we understand all the facts and science holistically.
“Good science should lead to the right political negotiations, as opposed to jumping to haphazard conclusions based on partial understandings that may lead to Egypt’s own detriment,” she concludes.

Ethiopia's Gibe III - A dam too far?
Published on : 20 December 2011 - 3:24pm | By RNW Africa Desk (Photo : RNW)
More about: Dasanech tribe Ethiopia dam Kenya Lake Turkana Turkana tribe
Michael Irgiena doubts if his ten children will ever be fishermen like him, or have any future living on the shores of the world’s largest desert lake Turkana in the barren border region of Ethiopia and Kenya.

By Luc van Kemenade, Addis Ababa

Lake Turkana, in the barren border region of Ethiopia and Kenya, is home to the Dasanech and Turkana tribes. Michael, a Dasanech tribesman living in a small village in northern Kenya, has been a fisherman for 26 years and, like his fellow tribesmen, he fully depends on the salty lake for his livelihood.

The semi-nomadic desert tribes often fight bloody battles over the region's scarce water and pasture which they use for fishing and cattle grazing. But the construction of an ambitious cascade of dams along Ethiopia's Omo river may pose a serious threat to the livelihood of nomads in the region, explains Michael.

“I was shocked when I heard the news about Ethiopia’s dam on the radio,” he says while sitting on his bed in his dusky dome-shaped hut at the shores of Turkana. “What came to mind very quickly was: what about the lake I am fishing in? What about my children?”

Hydropower
Gibe III is a two billion dollar dam funded by the Ethiopian government and one of Africa’s largest hydropower dams in the Omo River that flows into Lake Turkana. It provides 90 percent of the region's water and is said to have nearly doubled the power capacity of East African nations.
According to the Ethiopian government, the dam will develop the region and end a “backward lifestyle”, transforming its southern wilderness into highly productive cultivated farm land, irrigated by the dam’s regulated outflow. It is hoped that domestic and foreign investors will grow sugar cane and other cash crops on a large-scale in the south, an area known for its numerous indigenous tribes.

But Michael is more cautious. “The water will be too salty, so there will be no fish living in the lake,” he says. “And all the animals we have, all the cattle, will die. If there is no water, there will be no grass.”

He also fears the dam will lead to further bloodshed among tribes, as the Dasanech and Turkana will be forced to move into neighboring tribes’ territory in search of water and pasture.

Drying up
While Ethiopia denies that its dam will reduce water levels, a group of scholars from the United States, Europe and East Africa shares Michael’s concerns.

In a 2009 study the Africa Resources Working Group estimated that water levels could drop ten to twelve meters drying up fish stocks and potable water. The United Nations subsequently called on Ethiopia to cease construction of the dam, fearing it would destroy Lake Turkana, listed as a UN world heritage.

But Ethiopia says there is “no way” that the project will be stopped, claiming its own studies show that Lake Turkana’s water levels would increase and the dam’s regulated flow would put an end to drought and floods.

Like other members of the Dasanech, Michael fears that Ethiopia’s decision to move forward with the project without informing its people will have a negative impact: “If you do something without informing people, you know it will have an effect,” he says. “It would be better if we all sit together and negotiate about what they are going to do for our people.”

Nile Waters -Terms Of Reference Agreed For The International Panel Of Experts On The Nile Dam

On Tuesday and Wednesday this week a tripartite meeting of ministers from Egypt, Ethiopia and Sudan, was held here in Addis Ababa. Attended by Egypt’s Minister of Water Resources and Irrigation, Ethiopia’s Minister of Water and Energy and the Minister of Irrigation and Water Resources of the Republic of Sudan, the aim of the meeting was to discuss and to agree on draft terms of reference for the establishment of the International Panel of Experts being set up to assess the impact of the Grand Ethiopian Renaissance Dam on the Blue Nile. After discussions and exchanges of ideas on the draft it was adopted with certain amendments.

In accordance with the TOR the three countries have agreed to form an International Panel of Experts with ten members in all, two experts from each of the three countries and another four international experts. The meeting agreed on a time frame for the nomination of national members, two weeks from the end of the meeting. The names of the independent international experts are to be agreed within four weeks of exchanging of the names of the respective national teams. The work of assessing the impact of the Renaissance Dam on the downstream countries is expected to be finalized within nine months but this can be adjusted according to the request of the panel itself.

Ethiopia’s Minster of Water and Energy, Ato Alemayehu Tegenu, said the meeting had immense significance and opened a new chapter of cooperation by enhancing transparency, the exchange of information, trust and confidence among three sisterly countries. He indicated that several of the studies undertaken on the Nile had clearly shown that there was ample potential and a real window of opportunity for further development and it was these findings that that had lead to the initiation of the Grand Ethiopian Renaissance Dam. The Minister stressed that Ethiopia was in need of huge energy resources to satisfy an ever growing demand, but the dam would also serve as the initiative to boost regional economic integration. Dr Hesham Kandil, Egypt’s Minister of Water Resource and Irrigation, and Engineer Kamal Ali, Sudan’s Minister of Irrigation and Water, expressed their appreciation for the holding of the Tripartite Ministerial Meeting to establish the International Panel of Experts. They both emphasized that the meeting was a manifestation of cooperation among the three countries and indicated it would form a good foundation for future and lasting cooperation, both for the Renaissance Dam and in other areas.

Before the ministerial meeting opened, experts from Ethiopia and Egypt discussed the decisions passed at the third and fourth meetings of the Ethiopia–Egypt Joint Ministerial Commission to establish the Technical Advisory Committee aimed to provide smooth implementation of cooperation between Ethiopia and Egypt in the areas of water resources and irrigation. During this meeting, the Technical Advisory Committee developed its rules of procedure and agreed an action plan for the implementation of the Memorandum of Understanding signed between the two governments on 17th September regarding cooperation on Water Resources and Irrigation. The Arab Republic of Egypt has allocated two million Egyptian pounds for the capacity building and training for this year. According to the action plan Egypt is offering PhD programs to three candidates, MSc programs for seven candidates and other short term annual training over the next years for Ethiopian students. The two countries are also working to strengthen and renew their bilateral relations. During its visit, the Egyptian delegation took the opportunity to visit the Addis Ababa University’s Faculty of Technology. --mfa
