    Climate, politics double threat as Tigris-Euphrates shrivels

    [ad_1]

    DAWWAYAH, Iraq and ILISU DAM, Turkey — Next year, the water will come. The pipes have been laid to Ata Yigit’s sprawling farm in Turkey’s southeast connecting it to a dam on the Euphrates River. A dream, soon to become a reality, he says.

    Over 1,000 kilometers (625 miles) downstream in southern Iraq, nothing grows anymore in Obeid Hafez’s wheat farm. The water stopped coming a year ago, the 95-year-old said.

    The starkly different realities are playing out along the length of the Tigris-Euphrates river basin, one of the world’s most vulnerable. River flows have fallen by 40% in the past four decades as countries along its length — Turkey, Syria, Iran and Iraq — pursue rapid, unilateral development of the waters’ use.

    The drop is projected to worsen as temperatures rise from climate change. Both Turkey and Iraq, the two biggest consumers, acknowledge they must cooperate to preserve the river system. But a combination of political failures, mistrust and intransigence are conspiring to prevent a deal on sharing the rivers.

    The Associated Press conducted more than a dozen interviews in both countries, from top water envoys and senior officials to local farmers, and gained exclusive visits to controversial dam projects. Internal reports and revealed data illustrate the calculations driving disputes behind closed doors, from Iraq’s fears of a potential 20% drop in food production to Turkey’s struggles to balance Iraq’s and its own needs.

    “I don’t see a solution,” said former Iraqi Prime Minister Haidar al-Abadi.

    “Would Turkey sacrifice its own interests? Especially if that means that by giving more (water) to us, their farmers and people will suffer?”

    Turkey has been harnessing the river basin with a massive project to boost agriculture and generate hydroelectricity, the Southeast Anatolia Project, or GAP by its Turkish acronym. It has built at least 19 dams on the Euphrates and Tigris, with several more planned for a total of 22. The aim is to develop Turkey’s southeast, long an economic backwater.

    For the farmer, Yigit, the project will be transformative.

    Until now, his reliance on well water only permitted half his lands to be irrigated.

    But now that the irrigation pipes have reached his farm in Mardin province, his entire 4,500 acres will be watered next year via the Ataturk Dam on the Euphrates.

    In contrast, Iraq — which relies on outside sources for nearly all its water — grows more worried with every drop diverted upstream.

    In 2014, its Water Ministry prepared a confidential report warning that in two years, Iraq’s water supply would no longer meet demand, and the gap would keep widening. The report, seen by the AP, said that by 2035, the water deficit would cause a 20% reduction in food production.

    The report shows Iraqi officials knew how bleak the future would be without the recommended $180 billion in investment in water infrastructure and an agreement with its neighbors. Neither has happened.

    Decades of talks have still not found common ground on water-sharing.

    Turkey approaches the water issue as if it were the river basin’s benevolent owner, assessing needs and deciding how much to let flow downstream. Iraq considers ownership shared and wants a more permanent arrangement with defined portions.

    In a rare interview, Turkey’s envoy on water issues with Iraq, Veysel Eroglu, told the AP that Turkey cannot accept to release a fixed amount of water because of the unpredictability of river flows in the age of climate change.

    Eroglu said Turkey could agree to setting a ratio to release — but only if Syria and Iraq provide detailed data on their water consumption.

    “That is the only way to share water in an optimal and fair manner,” Eroglu said.

    Iraq refuses to provide its consumption data. That’s in part because it would show the widespread water waste in Iraq and the government weakness that makes managing water nearly impossible.

    Government attempts at rationing the waning water causes outrage in southern Iraq. In August in southern Dhi Qar province, for example, tribal leader Sheikh Thamer Saeedi and dozens of protesters tried to divert water from a Tigris tributary to feed his barren lands after authorities failed to respond to his pleas for water.

    The attempted diversion nearly sparked violence between local tribes before security forces intervened.

    Iraq blames one Turkish infrastructure project in particular for these woes: the Ilusu Dam, on the Tigris.

    Before Turkey began operating the dam in 2020, all the waters of Tigris flowed into Iraq. Now how much water comes down depends on Ankara’s consideration of Iraq’s month-to-month requests for a minimum flow, weighed against Turkey’s own hydropower needs.

    Turkey contends it is unfairly scapegoated. The AP was given an exclusive tour of the dam facility in October by Turkey’s State Hydraulics Works, known by the Turkish acronym DSI, and given figures for the first time detailing flow rates and electricity production over two years.

    A decade ago, Iraq received an average flow of 625 cubic meters of water per second from the Tigris. Today, the rate averages only 36% of that, Iraqi water ministry officials say.

    Data provided by DSI shows that Turkey respected a request made by Iraq that it release at least 300 cubic meters per second down the Tigris during summer months when shortages are common.

    But Iraqi officials say depending on such ad hoc arrangements make planning difficult.

    “They can cut water, they can release water. We urgently need a water agreement just to satisfy Iraq’s minimum requirements,” said Hatem Hamid, head of the National Centre for Water Resources Management.

    For example, with dire shortages anticipated in 2022, Hamid cut the state agriculture water plan in half and reduced fresh water flows to Iraq’s marshlands, to minimize salinity. But water-stressed Iran also diverted flows from tributaries feeding the marshes. The result was an environmental emergency and hundreds of dead livestock.

    Back in Obeid Hafez’s farm, the land is barren.

    Portraits of Hafez’s forefathers hang in his spartan living room. With his sons gone to seek work in the cities, there will be no one to till the land after him.

    “Life has ended here,” he said.

  • US regulators to vote on largest dam demolition in history

    US regulators to vote on largest dam demolition in history

    [ad_1]

    PORTLAND, Ore. — The largest dam demolition and river restoration plan in the world could be close to reality Thursday as U.S. regulators vote on a plan to remove four aging hydro-electric structures, reopening hundreds of miles of California river habitat to imperiled salmon.

    The vote by the Federal Energy Regulatory Commission on the lower Klamath River dams is the last major regulatory hurdle and the biggest milestone facing a $500 million demolition proposal championed by Native American tribes and environmentalists for years.

    Approval of the application to surrender the dams’ operating license is the bedrock of the most ambitious salmon restoration plan in history, and if approved the parties overseeing the project will accept license transfer and could begin dam removal as early as this summer. More than 300 miles (482.80 kilometers) of salmon habitat in the Klamath River and its tributaries would benefit, said Amy Souers Kober, spokeswoman for American Rivers, which monitors dam removals and advocates for river restoration.

    “This is an incredibly important milestone,” she said. “This project really carries important lessons for rivers and the conservation movement, and the most important lesson is the leadership of the tribes. It’s because of the tribes that these dams will come out and the river be will restored.”

    The vote comes at a critical moment when human-caused climate change is hammering the Western United States with prolonged drought, said Tom Kiernan, president of American Rivers. He said allowing California’s second-largest river to flow naturally, and its flood plains and wetlands to function normally, would mitigate those impacts.

    “The best way of managing increasing floods and droughts is to allow the river system to be healthy and do its thing,” he said.

    “Instead of having reservoirs where a significant amount of that water evaporates, it’s better to have that river flow and allow the flood plains and wetlands filter the water and bring it down to groundwater where it doesn’t evaporate.”

    The Klamath Basin watershed covers more than 14,500 square miles (37,500 square kilometers) and the Klamath itself was once the third-largest salmon producing river on the West Coast. But the dams, constructed between 1918 and 1962, essentially cut the river in half and prevent salmon from reaching spawning grounds upstream. Consequently, salmon runs have been dwindling for years.

    Native tribes that rely on the Klamath River and its salmon for their way of life have been a driving force behind bringing the dams down. Members of the Yurok, Karuk and Hoopa tribes plan to light a bonfire and watch the Federal Energy Regulatory Commission meeting Thursday on a remote Klamath River sandbar via a satellite uplink to symbolize their hopes for the river’s renewal.

    Frankie Myers, Yurok vice chairman, told The Associated Press before the meeting that he was excited, but also anxious, about the outcome of the vote.

    “We’ve been doing this a long time and we’ve been let down so much over the last two decades,” he said. “If there’s still salmon in the water, they have a chance and we have a chance. …They will come down. They have to come down. Our existence depends on it.”

    But plans to remove the dams have been controversial.

    A group of homeowners who live around Copco Lake, one of the large reservoirs, have fought the dam removal plans for years and say the values of their lakefront homes have plummeted. A coalition formed to oppose the demolition plan argues that the money set aside to cover the demolition isn’t adequate, and that cost overruns and liability concerns would fall on the shoulders of taxpayers.

    They also question whether removing the dams will work to restore salmon because of changes in the Pacific Ocean that are also affecting the fish, said Richard Marshall, head of the Siskiyou County Water Users Association.

    “The whole question is, will this add to the increased production of salmon? It has everything to do with what’s going on in the ocean (and) we think this will turn out to be a futile effort,” he said. “Nobody’s ever tried to take care of the problem by taking care of the existing situation without just removing the dams.”

    Rate payers in the rural counties around the dams are also angered by the project, which is funded by $200 million from PacifiCorp and $250 million from a voter-approved water bond in California.

    U.S. regulators raised flags about the potential for cost overruns and liability issues in 2020, nearly killing the proposal, but Oregon, California and PacifiCorp, which operates the hydroelectric dams and is owned by billionaire Warren Buffett’s company Berkshire Hathaway, teamed up to add another $50 million in contingency funds.

    The utility would face steep costs to add fish ladders and other environmental mitigations to the outdated dams in order to renew their hydroelectric license and in recent years has diversified their energy portfolio enough to absorb the loss of the dams, the company has said.

    If regulators approve on Thursday, Oregon, California and the Klamath River Renewal Corporation — the entity formed to oversee the demolition and environmental mitigation — must sign off on the license surrender and then work can begin. Regulators could also approve it, but add further specifications, or reject it altogether.

    If approved, Copco 2, the smallest dam, could come down as early as the coming summer, said Craig Tucker, natural resources policy consultant for the Karuk Tribe. In early 2024, the reservoirs behind the dams would be slowly drawn down, with the hope of putting the river fully back in its channel by late 2024, he said.

    The scope of the project exceeds the other largest U.S. dam demolition to date, when two century-old dams were breached on the Eolwha River on Washington’s Olympic Peninsula in 2012, said Kober, of American Rivers. Environmental experts are unaware of any other river restoration project in the world with a bigger scope than the one planned for the lower Klamath, she added.

    Across the U.S., 1,951 dams have been demolished as of February, including 57 in 2021, the organization said. Most of those have come down in the past 25 years as facilities age and come up for relicensing.
