Two dates
On 9 September 2025 Abiy Ahmed stood on the crest of the Renaissance Dam and spoke about brothers. Ethiopia, he said, "built the Renaissance Dam not to harm its brothers"; the hunger of Egypt and of Sudan "is also our hunger". The same day Egypt's permanent representative sent the president of the Security Council a letter, logged in the UN's records under that date, calling the launch a unilateral act in breach of international law. A year has passed. The dispute has not moved. It has changed genre, from negotiation to an exchange of accusations after each flood.
The date carries a second meaning 3,000 kilometres to the east. It is Tajikistan's independence day, the 35th this year, and Emomali Rahmon switched on Rogun's second unit to it in 2019. Rogun's dam is designed to stand 335 metres, more than twice the 145 metres of the Ethiopian one. The collision is the same in both places: the upstream builds a giant for electricity, while the downstream lives by irrigation and fears for its flow.
The Nile: what an escalation looks like
Egypt has one river. The Nile supplies about 97% of its renewable water, its population passed 107 million in November 2024 and adds more than 2 million births a year, and about 86% of the flow that reaches Aswan rises on the Ethiopian highlands. The law ran the other way for a century: the 1959 treaty with Sudan divided a mean flow of 84 billion cubic metres at Aswan into 55.5 billion for Egypt, 18.5 for Sudan and 10 written off to evaporation. Ethiopia, which sends the river most of its water, is absent from it and has never recognised it.
Addis Ababa chose its moment: the foundation stone went down at the start of April 2011, seven weeks after Mubarak fell. Egypt's one weapon was to keep the lenders away, and no multilateral bank financed the dam. Ethiopia paid 91% of the $5 billion itself, through bonds, payroll deductions and public fundraising, with about $1 billion from China's Exim Bank for the turbines, on Engineering News-Record's accounting. Construction took 14 years.
The talks ran alongside the concrete and delivered nothing. Of the three leaders who signed the 2015 Declaration of Principles in Khartoum, only Sisi is still in office. Washington's mediation in Trump's first term is remembered for one line, spoken to Sudan's prime minister on 23 October 2020: Egypt "will end up blowing up the dam". In December 2023 Egypt's irrigation ministry declared the fourth and final round of talks over.
The launch of 9 September 2025 registered a fact already in place: the flow of Egypt's river is now regulated by another state. Water, foreign minister Badr Abdelatty said in October, is "an existential Egyptian issue". Then the argument moved onto the water itself. When Sudan flooded in late September, Egypt's irrigation ministry accused Ethiopia on 3 October of "reckless" management and of having "suddenly discharged" about 2 billion cubic metres through the month; Ethiopia's water ministry answered the next day that the dam "has been essential in preventing a more catastrophic flood". The same cubic metres read as proof in both capitals.
In March 2026 Ethiopia's water and energy ministry set out plans for three more dams on the Blue Nile, Karadobi, Mandaya and Beko Abo, about 5,700 megawatts between them; Cairo's answer, in The National's headline of 29 December, was that there would be no more dams on the Nile without its approval.
Nobody shoots. Egypt and Ethiopia share no border; Sudan, between them, has been at war with itself since April 2023; and a strike on a full reservoir would send the water down through Khartoum before any of it reached Egypt. What remains is a war of nerves in which war is physically impossible, with one refinement: it has no referee. The escalation needs no shots. It also has no exit.
Central Asia played the same script first, and it is the only place that has walked out of it.
The Amu Darya: the conflict that was bought
The Soviet planners drew the region as one organism. The upstream, Tajikistan and Kyrgyzstan, stored water in winter and released it in summer for the cotton of the plains; Uzbek gas and Kazakh coal travelled the other way. Uzbekistan forms about a fifth of the water it uses on its own territory. After 1991 every invoice in that exchange became a lever.
Rogun is the Soviet project that never closed: the upper step of the Vakhsh cascade, begun in 1976, stopped by the collapse of the Union and Tajikistan's civil war. Islam Karimov met it with an arsenal Cairo would have envied. Uzbekistan's railway held up freight bound for Tajikistan from 2010; gas deliveries were suspended in January 2012 and stopped from 1 April that year, on grounds of non-payment, and did not resume until 2018. Karimov told the people of Karakalpakstan that filling Rogun's bowl would leave Uzbekistan without water for 8 years. In September 2012 came the sentence of the era. Water disputes, he said, could cause serious confrontation, "even wars".
The symmetry is almost literal. Cairo kept the World Bank out of the Renaissance Dam; under Karimov outside money never reached Rogun either. Rahmon answered in kind. From 2010 the state sold Rogun shares to its own population, and between 2008 and 2024 the budget put 42.5 billion somoni, about $4 billion, into the site.
The turn came in September. Karimov died on 2 September 2016. On 29 October Rahmon sat at the controls of a bulldozer at the ceremony that diverted the Vakhsh, and the construction restarted. The wall began to rise. In March 2018, on his first state visit to Dushanbe, Shavkat Mirziyoyev declared Uzbekistan's readiness to consider taking part in Rogun. When the first unit was switched on that November, the most important guest, in Kommersant's description, was Uzbekistan's water minister, Shavkat Khamraev.
Once the main opponent laid down its arms, the money the project had waited half a century for arrived. The World Bank's Rogun Coordination Group has 12 members; its plan for the first phase is $2.97 billion in grants and concessional money towards a total project cost of $6.29 billion, and the Bank itself granted $350 million in December 2024 and $300 million more in June 2026. The third unit is promised for September 2027. At the end of 2025 the wall stood at 151 of its 335 metres, the works about 60% done.
The culmination is a contract. In July 2025 Rogun's operator and Uzbekistan's single buyer, Uzenergosotish, signed a 20-year agreement: 3.4 cents a kilowatt-hour including VAT at the zero rate, indexed 1% a year from the second year, and, while the dam is still being built, deliveries only from 1 April to 30 September. The construction deserves a second reading. The state that threatened war over a dam now pays for its electricity in exactly the months when the water passing through the turbines irrigates that state's own fields. The conflict has been put on a tariff.
The deal sits on the Bank's covenants, and the Bank's accountability machinery has already been tried on it. In February 2025 the Rivers without Boundaries fund in Almaty lodged a request for inspection on behalf of two residents of Turkmenistan and Uzbekistan downstream. The Inspection Panel recommended an investigation in June, finding "a plausible link" between the alleged harm and the project; in November the Board found the request ineligible and closed the case, and seven months later the Bank approved its second grant. The larger test is ahead: the reservoir will take years to fill, and every dry year will move the release formulas into politics.
The mechanism worked because both capitals live inside the world's financial system, under a referee with money. The third player on the Amu Darya has no account at the World Bank and no intention of opening one.
Qosh Tepa: a Renaissance Dam without brakes
While Tashkent and Dushanbe agreed tariffs, digging began on the Amu Darya's left bank. On 30 March 2022, seven months after taking Kabul, the Taliban broke ground on the Qosh Tepa canal: about 285 kilometres long, 100 metres wide and 8.5 deep. The first 108-kilometre section was completed in October 2023, eight months ahead of schedule. By the National Development Corporation's count in late October 2025 the second phase's earthworks were 95% done; no later figure surfaced in the channels CAW read. The target is about 555,000 hectares of new farmland in Balkh, Jawzjan and Faryab and, by the Afghan estimate, $470 to 550 million a year of income.
The conflict has been put on a tariff.
The rhetoric follows a familiar score. Asked about Tashkent's concern in October 2023, water and energy minister Abdul Latif Mansur said Mirziyoyev's worry "would be appropriate if obligations under a treaty had been violated. In this case we have taken on no obligations. There is no treaty. So we do what we consider necessary." That is Addis Ababa's logic on the treaties of 1929 and 1959, and Kabul's footing is firmer: the Almaty agreement of February 1992 that divided the river was written by five republics.
Estimates of the withdrawal diverge. The cautious figure is 4 to 4.5 cubic kilometres a year; the ICWC's portal expects 9 to 11 after completion, 15 to 18% of the 62 cubic kilometres it takes as the river's mean flow; Kabul's own plan, as Asia-Plus reported it in August, is 6 to 10, and a former Afghan minister says no more than 12% of the river. The first 40 kilometres of the canal are lined with concrete over a geomembrane; the rest is earth, and the seepage into sand adds to the real offtake.
The downstream's reaction has been unusually quiet. At the Aral Sea fund's summit in Dushanbe on 15 September 2023 Mirziyoyev proposed a joint working group on the canal and Afghan participation in the regional water dialogue; Mansur's reply is quoted above. Khamraev has been to Afghanistan four times, was received "like family", and said in public that the interim government too "has a right to water from the Amu Darya".
Softness is easy to explain: the old arsenal does not reproduce. A transport blockade is ruled out by the opposite logic, because the trans-Afghan corridors are Tashkent's own route to Pakistani ports. Uzbekistan sends Afghanistan no gas to cut off. It does send electricity, and has since 2002; in August its energy minister said exports would be covered only by "the part that remains after domestic demand is fully met". That is the one switch Tashkent holds, and it has described it as a surplus.
Rogun's mechanism assembles even less. A banking consortium presupposes a borrower who needs grants, ratings and donors' approval; Kabul builds on its own money under sanctions. And the Rogun trade paid the upstream for water passed through turbines; a canal has no turbines. A dam passes water through and argues about timetables; a canal takes it out, onto fields and into the air. By the physics of the conflict Qosh Tepa is harsher than either famous dam, and there is nobody to argue with, because no international mechanism exists for the case.
Two ways to take a river: a dam passes the water through on its own timetable; a canal takes it out. Rogun and the Renaissance Dam are the loop; Qosh Tepa is the branch.
The appetite grows: among Kabul's further plans, Nova24 reports, is a hydro scheme at Dashtijum on the Panj, Tajikistan's border river, which would put Rogun and the Afghan projects on one river in the literal sense. For a movement most of the world does not recognise, the canal is the emirate's first megaproject, proof that it can build. Water is fuel for a political regime again.
The dam as a legitimacy machine
Three projects, three unlike regimes, one political genre. For a poor country a dam is the most accessible format of a national idea, sold to the population at retail, by share, by bond, by payroll deduction. Ethiopia raised the Renaissance Dam for 14 years on its citizens' money, and for a government that came through the Tigray war it is the rare achievement it can show every ethnic group at once. Rahmon's construction calendar is sewn to the state's: the second unit was switched on for independence day in 2019, the third is promised for the 36th anniversary, and the population has been enrolled as shareholders of the project of the century. For the Taliban the canal stands in for recognition.
The machine has two drives, and that is the important part: the conflict feeds the other bank too. A former US official who mediated on the dam under Biden told Euronews last November that "al-Sisi actually benefits from this threat of an external enemy, a domestic political matter", the more so as wheat prices rose after Russia's invasion of Ukraine. Karimov spent a decade mobilising Uzbekistan around the anti-Rogun slogan; Radio Ozodi wrote in December 2011 that it had become "political capital" for both presidents at once.
Hence the central trouble of water conflicts: a settlement writes down an asset held by two rulers, so the status quo outlives common sense. The Amu Darya knot came undone only when one holder of the capital died; Mirziyoyev inherited the conflict as a liability and wrote it off. On the Nile both holders are alive. There is no trade. While water stays political fuel, water treaties burn first. Everywhere, in fact.
A world where water has no referee
Oil has a world price and tankers; water in industrial volumes is sold only to neighbours in the basin, and its price is always political. The world's water market is a stack of treaties between upstream and downstream. This decade it caught fire.
The loudest fire is the Indus. The 1960 treaty, midwifed by the World Bank, gave the three western rivers and roughly 80% of the flow to Pakistan, the three eastern and 20% to India. On 22 April 2025 gunmen killed 26 tourists at Pahalgam in Kashmir; the next day India put the treaty in abeyance, the first suspension in 65 years. In May the two countries traded strikes for four days and each counted its dead in dozens; the ceasefire of 10 May was announced by Trump, whose mediation Delhi denies, and the water freeze outlived it. Modi's doctrine fitted one sentence, on 12 May: "blood and water cannot flow together".
Islamabad's reply is legally impeccable and practically powerless. The treaty has no exit clause, and Pakistan's National Security Council declared in advance that any diversion of its water would be "treated as an act of war". India cannot stop the Indus quickly, since diverting the western rivers means dams and canals that take years; politically it has already happened.
The law has answered, 8 days before this text. On 31 August 2026 the Court of Arbitration in The Hague ruled that "the Indus Waters Treaty remains fully in force, and India must observe its obligations under the Treaty", and ordered India not to pour concrete above set elevations at the Ratle plant until 90 days after the neutral expert's final determination. India calls the court illegally constituted and does not appear before it. A treaty can be alive at The Hague and dead on the river at the same time.
The vector is the same on every big basin. Turkey holds that the Euphrates and Tigris are its transboundary rivers, to which an international regime does not apply; China built its cascade on the upper Mekong and is only a dialogue partner of the downstream states' commission. The UN convention on international watercourses, adopted in 1997 with China and Turkey voting against, waited 17 years to enter into force and has gathered around 40 parties; Uzbekistan acceded in 2007; its four neighbours have not, on the status list CAW could open. The one working referee left is the World Bank, midwife of the Indus treaty and guarantor of Rogun, and its limit runs one basin at a time: in 2025 it could not hold its own creation on the Indus, and its president, Ajay Banga, said in May that the Bank had "no role to play beyond a facilitator".
Climate presses on the structure from the other side. Up to 74% of the Amu Darya's flow comes from snow and glacier melt, the Asian Development Bank's adaptation expert Chris Dickinson said in December, as Asia-Plus reported, of Glaciers to Farms, a programme that envisages up to $3.5 billion with $250 million approved by the Green Climate Fund. The International Centre for Integrated Mountain Development says a 1.9°C rise would cost the region up to half its glaciers. Melt adds water to the rivers for some years, then the curve turns down, while the five states' population is about 85 million. The bargaining will be over a shrinking resource.
So the question of the century sounds plain: will there be places where water can be exchanged for something other than threats? On the Nile, none. On the Indus one was burned in a day. Central Asia made the exchange.
9 September, again
On 9 September 2026 the plots of this text meet on one calendar page. Addis Ababa has a dam a year old and a letter from Cairo on file at the Security Council with the same date on it. Dushanbe celebrates its 35th independence day with a third unit promised for the 36th. And on the Amu Darya's left bank the second phase of a canal on which not one document has been signed stood at 95% at Kabul's last published count. Central Asia is the one region that has bought itself peace on water: a conflict converted into a tariff, threats into a 20-year contract. Qosh Tepa tests whether that peace can be sold twice. The test has begun.
The region does have a currency for the bargaining that Cairo never had, and it is electricity. Afghanistan is already Tajikistan's largest paying customer: of 2.66 billion kilowatt-hours of commercial exports in 2025, 1.76 billion went south, for 742.3 million somoni. The CASA-1000 line to Pakistan crosses Afghan territory, where the World Bank restarted the works in December 2024 for completion at the end of 2027. The Soviet barter of water for energy may have to be invented again, with Kabul at the other end of the wire, and then Rogun, half a century the apple of discord, becomes the main argument for peace: summer megawatts are the one thing the region can offer the owners of the new trench.
The upstream no longer asks. It can still be bargained with, for as long as there is something to bargain with.
