One of the world's greatest rivers has been reduced to a trickle in places by a series of giant Chinese dams and engineering works which are threatening the livelihoods of up to 100 million people in Southeast Asia.
A body representing four downstream governments reported on Wednesday that the Mekong was at its lowest recorded level, flowing "close to rock bottom" near the end of a 4,800km journey that takes it from the Tibetan plateau, through China's Yunnan province, Burma, Thailand, Laos, Cambodia and Vietnam.
The Mekong's downstream countries, which are almost completely dependent on the river and its tributaries for food, water and transport, fear that China's plans for a further six major dams on the river could be disastrous.
"China holds all the trump cards," said one water analyst who asked not to be named. "If all these dams go ahead, the river's hydrology will be significantly altered and no-one can begin to understand the social or ecological consequences. China can do what it wants with impunity. It is a dangerous situation."
In recent months huge, previously unseen sandbanks have started emerging from the murky waters along the river's lower stretches, making navigation increasingly hazardous. According to the Mekong River Commission (MRC), a joint Lao, Cambodian, Thai and Vietnamese governmental body set up to oversee the health of the Mekong, monitoring stations show the river well below previous lowest levels recorded.
"We are very concerned," said Pech Sokhem, an MRC director in Phnom Penh. "It is very bad for agriculture and fishing. If the water doesn't flow properly, the fish will not spawn or migrate."
"The river has been getting shallower for many years now," said Yang Yara, a ferryman near Phnom Penh. "It makes my life hard because my boat is always getting stuck on islands and mud banks."
"Not only is the Mekong the lowest in history, it is also fluctuating -- sometimes up, sometimes down. This comes from dam operations in China," said Chainarong Setthachua, director of Cambodia-based environmental group South East Asia Rivers Network.
Low rainfall last year is partly to blame for the river levels, as is increased use of water by growing populations along the whole length of the river, but Chinese dam-building in the upper stretches of the Mekong is thought to be responsible for many of devastating consequences downstream.
The Manwan hydroelectric dam across the upper Mekong, finished in 1996, has been frequently blamed by Thailand and other countries for reduced fishing and also for causing flash floods when water is released unpredictably.
A second giant dam, at Dachaoshan, is almost complete but is said to be already affecting the river flow, and a third is due for completion in 2012. None of them, say the countries downstream, has been fully assessed for its social or ecological impacts outside China, which hopes to generate the equivalent in clean electricity of 15 major power stations from the first three dams.
All the other countries which share the Mekong have ambitious plans to engineer their own lengths of river. The Mekong, only 20 years ago one of the most untouched rivers, could become one of the most dammed in the world with more than 100 other major dams, diversions and irrigation projects planned and thousands of smaller schemes already impacting on people downstream.
The governments, mostly without any other major resources, have been keen to back river developments in their own countries, believing that they can export the electricity generated to growing industrial centers in China and Thailand.
Last year the Asian Development Bank, working with Norwegian hydropower company Norconsult, recommended a US$43 billion electricity generation and transmission system for the region which included major dams in Laos, China, Burma and Cambodia.
But there is little official concern for the remote communities who are most affected by the dams.
Laos is about to experience some of the worst effects of dam-building, says the International Rivers Network, a powerful US-based group backed by Booker prize winner, turned water activist, Arundhati Roy. It fears that the proposed US$1.1 billion World Bank financed Nam Theun dam on a tributary of the Mekong will impoverish up to 120,000 people, displace 5,700 people and saddle the country with enormous debts.
The bank, which has been forced to pull out of many large dam schemes in the past because of the social effects, says the dam will aid development. But all the electricity generated is expected to go to Thailand.
The cumulative impacts of the Mekong dams are likely to deeply affect Cambodia, where the river's annual floods create the world's fourth largest catch of freshwater fish and work for 1.5 million people.
Cambodia catches 400,000 tonnes of freshwater fish a year, ranking it only behind China, India, and Bangladesh, but annual river levels are thought to have dropped at least 12 percent since the dams and irrigation works started upstream.
Ecologists fear that the situation could worsen rapidly if the proposed US$4 billion Sambor dam is built. This is expected to flood more than 4,800km2, displacing 60,000 people and affecting fishing.
FLYBY: The object, appears to be traveling more than 60 kilometers per second, meaning it is not bound by the sun’s orbit, astronomers studying 3I/Atlas said Astronomers on Wednesday confirmed the discovery of an interstellar object racing through the solar system — only the third-ever spotted, although scientists suspect many more might slip past unnoticed. The visitor from the stars, designated 3I/Atlas, is likely the largest yet detected, and has been classified as a comet, or cosmic snowball. “It looks kind of fuzzy,” said Peter Veres, an astronomer with the International Astronomical Union’s Minor Planet Center, which was responsible for the official confirmation. “It seems that there is some gas around it, and I think one or two telescopes reported a very short tail.” Originally known as A11pl3Z before
US President Donald Trump’s administration on Monday accused Harvard University of violating the civil rights of its Jewish and Israeli students, and threatened to cut off all federal funding if the university does not take urgent action. Harvard has been at the forefront of Trump’s campaign against top US universities after it defied his calls to submit to oversight of its curriculum, staffing, student recruitment and “viewpoint diversity.” Trump and his allies claim that Harvard and other prestigious universities are unaccountable bastions of liberal, anti-conservative bias and anti-Semitism. In a letter sent to the president of Harvard, a federal task
‘CONTINUE TO SERVE’: The 90-year-old Dalai Lama said he hoped to be able to continue serving ‘sentient beings and the Buddha Dharma’ for decades to come The Dalai Lama yesterday said he dreamed of living for decades more, as the Buddhist spiritual leader prayed with thousands of exiled Tibetans on the eve of his 90th birthday. Thumping drums and deep horns reverberated from the Indian hilltop temple, as a chanting chorus of red-robed monks and nuns offered long-life prayers for Tenzin Gyatso, who followers believe is the 14th reincarnation of the Dalai Lama. Looking in good health, dressed in traditional maroon monk robes and a flowing yellow wrap, he led prayers — days after confirming that the 600-year-old Tibetan Buddhist institution would continue after his death. Many exiled Tibetans
Hundreds of protesters marched through the Mexican capital on Friday denouncing gentrification caused by foreigners, with some vandalizing businesses and shouting “gringos out!” The demonstration in the capital’s central area turned violent when hooded individuals smashed windows, damaged restaurant furniture and looted a clothing store. Mexico City Government Secretary Cesar Cravioto said 15 businesses and public facilities were damaged in what he called “xenophobic expressions” similar to what Mexican migrants have suffered in other countries. “We are a city of open arms... there are always ways to negotiate, to sit at the table,” Cravioto told Milenio television. Neighborhoods like Roma-Condesa
