China begins building world’s largest dam, fuelling fears in India

Chinese authorities have begun constructing what will be the world’s largest hydropower dam in Tibetan territory, in a project that has sparked concerns from India and Bangladesh.

Chinese Premier Li Qiang presided over a ceremony marking the start of construction on the Yarlung Tsangpo river on Saturday, according to local media.

The river flows through the Tibetan plateau as well as multiple South Asian nations. The project has attracted criticism for its potential impact on millions of Indians and Bangladeshis living downriver, as well as the surrounding environment and local Tibetans.

Beijing has said the development will prioritise ecological protection and boost local prosperity.

When completed, the $12bn yuan ($1.67bn; £1.25bn) project – also known as the Motuo Hydropower Station – will overtake the Three Gorges dam as the world’s largest, and could generate three times more energy.

Experts and officials have flagged concerns that the new dam would empower China to control or divert the trans-border Yarlung Tsangpo, which flows south into India’s Arunachal Pradesh and Assam states as well as Bangladesh, where it feeds into the Siang, Brahmaputra and Jamuna rivers.

A 2020 report published by the Lowy Institute, an Australian-based think tank, noted that “control over these rivers [in the Tibetan Plateau] effectively gives China a chokehold on India’s economy”.

In an interview with news agency PTI . external earlier this month, Arunachal Pradesh chief minister Pema Khandu expressed concern that the Siang and Brahmaputra could “dry up considerably” once the dam was completed.

He added that the dam was “going to cause an existential threat to our tribes and our livelihoods. It is quite serious because China could even use this as a sort of ‘water bomb'”.

“Suppose the dam is built and they suddenly release water, our entire Siang belt would be destroyed,” he said. “In particular, the Adi tribe and similar groups… would see all their property, land, and especially human life, suffer devastating effects.”

India’s federal government has in the past expressed concerns to China about the impact of the dam on communities downriver. It also plans to build a hydropower dam on the Siang river, which would act as a buffer against sudden water releases from China’s dam and prevent flooding in their areas.

China’s foreign ministry has previously responded to India, saying in 2020 that China has a “legitimate right” to dam the river and has considered downstream impacts.

Bangladesh also expressed concerns to China about the project, with officials in February sending a letter to Beijing requesting more information on the dam.

Chinese authorities have long eyed the hydropower potential of the dam’s location in the Tibet Autonomous Region.

It’s in a massive canyon that is said to be the world’s deepest and longest on land, along a section where the Yarlung Tsangpo – Tibet’s longest river – makes a sharp U-turn around the Namcha Barwa mountain.

In the process of making this turn – which has been termed “the Great Bend” – the river drops hundreds of metres in its elevation.

Earlier reports indicated that authorities planned to drill multiple 20km-long tunnels through the Namcha Barwa mountain, via which they would divert part of the river.

Over the weekend a Xinhua report on Li Qiang’s visit said that engineers would conduct “straightening” work and “divert water through tunnels” to build five cascading power stations.

Xinhua also reported that the hydropower dam’s electricity would be mainly transmitted out of the region to be used elsewhere, while accommodating for Tibet’s needs.

China has been eyeing the steep valleys and mighty rivers in the rural west – where Tibetan territories are located – to build mega-dams and hydropower stations that can sustain the country’s electricity-hungry eastern metropolises. President Xi Jinping has personally pushed for this in a policy called “xidiandongsong”, or “sending western electricity eastwards”.

The Chinese government and state media have presented these dams as a win-win solution that cuts pollution and generates clean energy while uplifting rural Tibetans.

But activists say the dams are the latest example of Beijing’s exploitation of Tibetans and their land – and past protests have been crushed.

Last year, the Chinese government rounded up hundreds of Tibetans who had been protesting against another hydropower dam. It ended in arrests and beatings, with some people seriously injured, the BBC learned through sources and verified footage.

There are also environmental concerns over the flooding of Tibetan valleys renowned for their biodiversity, and the possible dangers of building dams in a region rife with earthquake fault lines.

Magnitude 7.4 quake hits off Indonesia’s Ternate, tsunami warning lifted

A magnitude 7.4 earthquake has hit the ⁠Northern Molucca Sea off the coast of the city of ⁠Ternate, in Indonesia, killing at least one person and triggering a tsunami warning that was subsequently lifted.

The United States Geological Survey (USGS) said Thursday’s quake, which was initially recorded at a magnitude of 7.8, struck at a depth of 35km (22 miles), greater than the early figure of 10km (six miles). There were no immediate reports of injuries.

The epicentre of the ⁠earthquake was about ⁠120km (75 miles) from Ternate, in Indonesia’s North Maluku ‌province.

Local authorities in some cities, such as Ternate and Tidore, were urged to prepare citizens for evacuation, while news channel Metro TV broadcast images of damaged buildings.

One person was killed when a building collapsed in the city of Manado in North Sulawesi province, a local search and rescue official told AFP news agency.

“The quake was felt strongly and around Manado … one person died and one person had a leg injury,” George Leo Mercy Randang told AFP by telephone. The victim was “buried under the rubble” of a collapsed building, he said.

The Hawaii-based Pacific Tsunami Warning Center (PTWC) initially said hazardous tsunami waves were possible within 1,000 kilometres (621 miles) of the epicentre along the coasts of Indonesia, the Philippines and Malaysia.

Within half an hour of the quake, waves up to 75 centimetres were recorded in North Minahasa and 20 centimetres in Bitung, both in the north of Sulawesi island, according to Indonesia’s BMKG geological agency.

Thirty-centimetre waves were also logged in North Maluku province.

The PTWC lifted its warning just over two hours after the tremor, saying the tsunami threat “has now passed”.

Indonesia straddles the so-called Pacific Ring of Fire, an area of high seismic activity where tectonic plates ‌meet ‌and earthquakes are frequent.

NASA successfully launches historic Artemis II moon mission

NASA's Artemis II mission to fly by the moon, comprising of the Space Launch System (SLS) rocket with the Orion crew capsule, lifts off from the Kennedy Space Center in Cape Canaveral, in Florida, the US [Aljazeera]

The Artemis II space mission has blasted off from the US state of Florida, sending four astronauts on a historic journey around the moon and marking the first time humans have travelled beyond low-Earth orbit in more than 50 years.

The mission, which launched on Wednesday, is a major step in the United States space agency NASA’s plan to return humans to the moon and eventually send astronauts to Mars.

The 32-storey rocket rose from NASA’s Kennedy Space Center in Cape Canaveral, where tens of thousands gathered to witness the liftoff.

The Artemis II crew – NASA astronauts Reid Wiseman, Victor Glover and Christina Koch, and Canadian Space Agency astronaut Jeremy Hansen – are set for a nearly 10-day journey around the moon and back, taking them farther into space than humans have travelled in decades.

“On this historic mission, you take with you the heart of this Artemis team, the daring spirit of the American people and our partners across the globe, and the hopes and dreams of a new generation,” said Charlie Blackwell-Thompson, the launch director. “Good luck, Godspeed Artemis II. Let’s go.”

Five minutes into the flight, Wiseman, the commander, saw the team’s target: “We have a beautiful moonrise, we’re headed right at it,” he said from the capsule.

Tensions were high in the hours leading up to the launch as hydrogen fuel began flowing into the rocket, a critical phase that had caused a dangerous leak during a countdown test earlier this year and forced a lengthy delay.

To NASA’s relief, no significant hydrogen leaks were detected this time. The launch team successfully loaded more than 700,000 gallons (2.6 million litres) of fuel into the Space Launch System rocket on the pad, a smooth operation that set the stage for the Artemis II crew to board.

NASA also had to resolve several technical issues ahead of liftoff, but was able to clear them without delaying the launch. One issue involved commands not getting through to the rocket’s flight-termination system, which is designed to send a self-destruct signal if the rocket veers off course and threatens populated areas.

That issue was quickly resolved, according to NASA. Engineers also troubleshot a battery in the Orion capsule’s launch-abort system after its temperature readings fell outside the expected range, but the problem was fixed and did not prevent the launch from going ahead.

The astronauts will spend the first one to two days in high Earth orbit carrying out extensive systems checks, including testing Orion’s life-support, propulsion, navigation and communications systems to make sure the spacecraft is ready for deep space.

Once those checks are complete, Orion will perform a critical engine burn known as translunar injection, which will send the spacecraft out of Earth’s orbit and onto a trajectory towards the moon.

The journey will take several days, during which the crew will continue monitoring spacecraft systems as they travel farther from Earth.

Orion will then fly behind the moon on a free-return trajectory, a path that naturally swings the spacecraft back towards Earth using the gravity of both the moon and Earth, with minimal fuel required. During this phase, the spacecraft will reach its greatest distance from Earth.

After the lunar flyby, the crew will spend several days travelling back to Earth while carrying out additional deep-space tests on power systems, thermal controls and crew operations.

As Orion approaches Earth, the capsule will re-enter the atmosphere at speeds of about 40,233km per hour (25,000 miles per hour), before splashing down in the Pacific Ocean, where recovery teams will retrieve the crew.

With half the world’s population not yet born when NASA’s Apollo astronauts last walked on the moon, Artemis is being presented as a new generation’s moon mission.

“There are a lot of people who don’t remember Apollo. There are generations who weren’t alive when Apollo launched. This is their Apollo,” NASA science mission chief Nicky Fox said earlier this week.
