With the recent signing of the Tibet Policy and Support Act by the president of the United States, which also addresses the strategic importance of the Tibetan Plateau, whose rivers remain one of the major sources of water to more than a billion people living in the downstream Asia countries, the importance of Tibet’s rivers once again comes into focus.

Last month, news about Beijing’s planned construction of a major dam on the Yarlung Tsangpo (in Tibetan, tsangpo means “river”) in Tibet has created a heated debate among scholars, policy analysts and strategists.

Most of the debate has circled around the implications of this project for India. However, one must not forget that the Tibetan Plateau is popularly known as the water tower of Asia, because 90% of the runoff from Tibetan rivers flows into China, Vietnam, Cambodia, Laos, Thailand, Myanmar, Bangladesh, India, Nepal, Bhutan and Pakistan, providing a steady supply of fresh water, food and energy.

The status of the Plateau of Tibet is unique, as it plays a triple role: It is Asia’s main freshwater repository, its largest water supplier, and its principal rainmaker. Hence it is not only about India, the water security of all of the eastern part of Asia depends on Tibet’s rivers.

The most dammed nation in the world

Since its takeover of Tibet, China has invested heavily in the constructions of major highways, connecting every part of Tibet to the major cities of China. For the past few decades, Beijing has also invested heavily in the construction of dams, one after another, in Tibet.

Michael Buckley, an award-winning Canadian journalist, is author of the 2014 book Meltdown in Tibet, which exposes that China is now on a mission to exploit Tibet’s natural resources leading to the ongoing destruction of Tibet’s environment, calling it “ecocide.”

Buckley writes, “At the tail end of those same rivers lie the world’s largest deltas. One way or another, close to 2 billion people rely on Tibet’s waters – for drinking, for agriculture, for fishing, for industry.”

These rivers are still providing similar ecosystem services to the downstream Asian countries that they provided for centuries before the onset of man-made interruption. Now with China’s construction of dams one after another, everything is changing year after year.

Currently China is one of the most dammed countries in the world. Centuries ago, one of the reasons for China’s construction of the Great Wall was for its security from the militant nomads from Mongolia; now it is building a “Great Wall of Concrete” for its “water security,” but in the process endangering the security and livelihood of downstream Asian countries.

Dechen Palmo, a research fellow at the Tibet Policy Institute (TPI), a think-tank of the Central Tibetan Administration (CTA) based in Dharamshala, India, specializes in Tibet’s transboundary rivers and the impacts of China’s damming on China-Occupied Tibet.


Dechen writes: “Over the last seven decades, the People’s Republic of China has constructed more than 87,000 dams. Collectively they generate 352.26 [gigawatts] of power, more than the capacities of Brazil, the United States, and Canada combined. On the other hand, these projects have led to the displacement of over 23 million people.”

Not only this, since the 1950s the Chinese have built some 22,000 dams that are more than 15 meters tall, roughly half the world’s current total. (The World Commission on Dams defines a “large dam” as one being “at least 15 meters in wall height from the base up.”) Imagine the irreversible damage these dams could do to the Asian populations who for centuries enjoyed the free flow of fresh water from free and independent Tibet.

International Rivers, a California-based non-governmental organization, and Michael Buckley have highlighted the impacts of dams in the following way: The high wall of dams itself blocks the migration of fish and other aquatic species and nutrient-rich sediments, leading to the disappearance of birds in floodplains, huge losses of forest, wetlands and farmland, erosion of coastal deltas, and many other impacts.

The blocking of water will also severely impact the irrigation-oriented Asian countries. A great amount of water is utilized in Asia for irrigation of rice, cotton and rubber. Half of the rice in the world is produced and consumed by India and China, while rice is also a staple in Myanmar, Bangladesh, Cambodia, Laos, Thailand, Vietnam and Indonesia.
A solution to Asian water insecurity

According to a United Nations report titled “World Population Prospects 2019,” the global population is expected to increase by 2 billion in the next 30 years, from 7.7 billion currently to 9.7 billion in 2050. As rice is one of the most widely consumed grains in the world and particularly in Asia, naturally more rice will be needed by 2050.


Rice is a water-intensive crop. Without the free flow of rivers from the Plateau of Tibet to the downstream Asian countries, which coincidentally include the top eight countries producing the highest volumes of milled rice in the world, a shortage of water will severely impact rice production.

A research paper titled “Projections of Water Stress Based on an Ensemble of Socioeconomic Growth and Climate Change Scenarios: A Case Study in Asia,” published on March 30, 2016, by a team of research scientists from Massachusetts Institute of Technology (MIT) found: “Economic and population growth on top of climate change could lead to serious water shortages across a broad swath of Asia by the year 2050.”

The MIT researchers also found that by 2050 in Asia, these factors would lead to about a billion more people becoming “water-stressed.” Hence the scarcity of water might change the course of relations among Asian countries and provoke conflict – something that has already happened in the past.

The Pacific Institute, a policy research think-thank founded in 1987 and currently based out of Oakland, California, has chronicled the small and large-scale conflicts fought throughout the centuries over water.

According to its research, the causes of water conflicts have been categorized into three sections:

Trigger: water as a root cause of conflict, where there is a dispute over the control of water or waterways.
Weapon: where water resources are used as a tool or weapon in a violent conflict.
Casualty: water resources as a casualty of conflict, where water resources are intentional targets of violence.

Through this categorization, the institute chronicled around 926 conflicts fought over water since as early as 3000 BC.

From the above developments in the past and China’s chaotic construction of thousands of dams, which is still an ongoing issue, one cannot deny that water resources are soon going to be very contentious, which is the subject of what renowned Indian strategist Brahma Chellaney’s book Water: Asia’s New Battleground.

If China’s current erratic, unscientific and inhumane dam-construction program continues unchecked, soon there will be transnational environmental movement across the Asian countries against China’s monopolistic control over Tibet’s rivers.

Asia is not only about the China Dream, the advancement of China’s strategic or national or party interests while undermining the interests of neighboring countries, including strategic interests. Rather, it is the combined dreams of Asian countries to bring forth the Asian Century.

In short, securing Tibet is not only about the Tibetan people, and Tibetan culture; it is more about securing permanent water security for India and Asia at large.

Tibet is "Third Pole and Water Tower of Asia": Rivers flowed throughout Asia

Dharamshala, India — With an elevation of more than 4,000 meters above mean sea level, the Tibetan Plateau physically dominates the geographical map of the world. The entire plateau stretches for almost 3,000 kilometers from west to east and 1,500 kilometers from south to north. It holds the Hindu Kush Himalayan Ice Sheet, considered as the largest ice mass and reservoir of fresh water apart from the two poles, hence the name ‘Third Pole’.

The Tibetan Plateau is the major resource of big rivers and a rich repository of indispensable freshwater resources that are shared across Asia. A large percentage of the world’s population depends upon rivers originating in Tibet, including the Indus, Ganges, Brahmaputra, Irrawaddy, Salween and Mekong rivers. Incomplete statistics show that there are more than ten rivers in Tibet with drainage areas greater than 10,000 square kilometers.

Tibet is also known as the ‘Water Tower of Asia’ as it serves as the source of ten major Asian river systems flowing into ten countries, including many of the most densely populated nations in the world: China, India, Pakistan, Nepal, Cambodia, Laos, Thailand, Vietnam, Burma, Bangladesh, and Bhutan. The rivers of Tibet are characterized by an uneven seasonal distribution of runoff, low water temperature, abundant flow, small inter-annual change, low sand content, and good water quality. Of the world’s 7.7 billion people, for more than 1 billion living in South Asia from Afghanistan to the Ganga-Meghna-Brahmaputra basin and in Southeast Asia, the rivers flowing from Tibet constitute the lifeline.

The Zachu or Mekong River, originating from central Tibet through Yunan province in China and then flowing through Laos, Thailand, Cambodia and finally ending its journey in Vietnam is the lifeline for the people living in Mekong-region countries. This river directly supports approximately 70 million people along its basin from fishermen to farmers.

Beyond the populations residing in the watersheds of these rivers are the additional millions of people who depend on monsoon rains drawn inland by the Tibetan Plateau. It was also indicated that the Southeast Asian monsoon that recharges most of the rivers downstream varies in intensity according to the snow cover on the Tibetan Plateau. For China alone, 30 percent of its fresh water supply is met from the rivers flowing from Tibet. These rivers give hope to and sustain life of millions of people downstream, from the arid plains of India and Pakistan to the rice paddies of Southeast Asian countries.

However, rapid population growth, industrialization and climate change threaten water security across South and South-East Asia. With China, India, Pakistan, Nepal, Vietnam, Bangladesh, Bhutan, Burma, Cambodia, Laos and Thailand all dependent on rivers that have their headwaters in Tibet, predicted water shortages threaten the livelihoods of millions of people living in countries downstream. Tibet is warming twice as fast as the rest of the world. Glaciers are melting, putting millions of people downstream at risk from floods, water shortages and sea level rises, threatening coastal communities.

China, which requires water to meet the needs of approximately 20 percent of the world’s population, has harnessed freshwater from the Tibetan plateau to meet its own food and water requirements by building dams, irrigation systems and creating water diversion projects. Despite the critical state of the Tibetan plateau which remains ecologically sensitive and seismically active due to its high elevation, China is still moving on with its ambitious plan to expand the hydropower generation on the headwaters of Asia’s major rivers — the Yangtze, Yellow, Brahmaputra, Indus, Mekong, and Salween Rivers.

Chinese control in Tibet places China in a dominant position to control Asia’s water sources. Dwindling water sources in the trans-boundary rivers of the Tibetan Plateau threaten water security and create a high potential for geopolitical conflict in the region. As a result of dam building, however, the countries downstream have been, and will remain, negatively affected through altered water flow and increased sedimentation.

The International Centre for Integrated Mountain Development (ICIMOD) has revealed alarming details about the sustainability of the Himalayan glaciers in the time of climate change. According to their findings, the current trend of melting glaciers suggests that the Ganges, Brahmaputra, Indus and other rivers across the northern India plains would most likely become seasonal rivers in the near future, flowing only in the monsoon season and drying up during winters. In this way, downstream agriculture will be seriously affected and soil salinity will increase.

World Wide Fund (WWF) for Nature, formerly known as World Wildlife Fund, named the Indus River as one of the world’s ten rivers most at risk. The Indus river which already faces an acute shortage of water flow due to climate change suffered more obstruction after China built a dam on the dying river (in Ngari, Western Tibet) without informing the downstream countries - India and Pakistan.

So far China has dammed every major river and its tributaries in Tibet and has unveiled plans to construct even more dams in the coming years. The Chinese dam building boom and its water transfer projects are creating additional worries to the lower riparian states, especially in India where it was estimated that by 2030 the water demand will be higher by 50 percent from the current demand of 740 billion cubic meters.

The damming activities along the upstream of Mekong have significantly affected the flow volume of the river. Fishing boats are seen stranded on the shores of the dried Mekong River in Mukdahan Province and at Nakhon Panam in Thailand. The livelihoods of the local fishermen and many other communities from Cambodia are threatened by the reduced flow of the river water but their concerned voices are muffled by the aid their government receives from China. Thailand has vested interests in China’s hydropower production as it purchases 3000 megawatts of power generated by Chinese dams. Economic interaction between the countries through which a river flows complicates the issue of trans-boundary river negotiations and creates confusion regarding future food and water security.

Not only are these rivers and tributaries dammed for generating electricity but some are also polluted with chemicals and other toxins dangerous for human consumption. Industrial activities also threaten the quality of Tibetan freshwater. Previous deforestation has created erosion and siltation. Mining and industrial development has contributed to pollution from heavy metals within Tibet. For instance, the tap water of Kumbum monastery in Amdo detected high concentrations of lead (Pb) due to a mining activity. Similar cases of mining chemicals polluting the natural water supply are common wherever mining activities are prevalent.

Tibetan land is delicate and it cannot absorb the river water diversion projects, constructions of dams, mining and transportation, industrial and other activities. Such activities are leading to receding glaciers in Tibet and in the Himalayas. There are also reports that the Tibetan nomads are gradually being made to shift from their traditional grassland and resettle in bleak villages. Unfortunately, these activities might invite eco-disaster. This might aggravate the meltdown of Himalayan glaciers, further resulting in the drying of rivers. Therefore, the Tibet water resources should be accepted as a global common. Any distortion in the ecology of Tibet and its delicate river system is likely to affect the global environment. The impact on Tibet’s landscape and its natural resources due to climate warming and human intervention will threaten not only the future food and water security of many nations but also their development.

Why the Tibetan Plateau Might Be the Ideal Spot for the Telescope of the Future

A team in China has identified a location that could give the Eastern Hemisphere its first major observatory

A team of Chinese scientists has identified a location on the Tibetan Plateau that could host some of the world’s most powerful telescopes. The high-elevation plateau has been considered for observatory sites before, but the paper published today in Nature pinpoints a site that holds particular promise. A multi-year assessment suggests the site meets all the key parameters for a world-class observatory, including dark skies, high elevation, low humidity and more.

Chinese astronomers are eager to get a powerful observatory in their country, “but first of all, we need to find a place to put the telescope” says Licai Deng, an astronomer at the Chinese Academy of Sciences and lead author of the study. Though China has a number of smaller observatories across the country, Deng says they’ve only recently been able to fund large telescope projects.

When Deng and his team began searching for an observatory site, they looked for a specific combination of factors. Unlike backyard telescopes amateur astronomers use to spot stars and planets on a cloudless night, high-sensitive, massive optical and infrared telescopes require extreme conditions. The telescope China hopes to build, says Deng, could have an aperture—the diameter of the telescope’s light-gathering lens or mirror—of 100 feet and be the world’s largest, at least for a short time. Europe’s Extreme Large Telescope, which is slated to be complete in 2027, has a primary mirror of 138 feet and is the largest telescope ever planned.

When selecting a location for an observatory, “we tend to look for the not any one individual trait, but the best, optimal combination of multiple traits,” says John O’Meara, chief scientist at the W.M. Keck Observatory in Mauna Kea, Hawai’i, who wasn’t involved in the work. Observatories need be remote enough to avoid the polluting light of nearby cities, but still possible for scientists to access. Telescopes should be built at high elevations to avoid blurring caused by the atmosphere, but not so high that humans can’t visit. Too much wind, dust or water vapor can impede a telescope’s accuracy.

As the region with highest elevation of any on Earth, the Tibetan Plateau has long been of interest to both Chinese and international astronomers. To narrow down their search on the Plateau, Deng and his team first looked at weather information and satellite data to find places with clear, dark skies. They were excited when they saw that the city Lenghu, which hadn’t been considered until then, had 3,500 annual hours of sunshine a year and barely a drizzle of rain. They then identified an ideal observatory site on the nearby Saishiteng Mountain, which sits 5,000 feet above the city.

In 2018, the team from the Chinese Academy of Science set up equipment on the mountain to monitor conditions that could interfere with a clear view of the sky: dust, cloud cover, turbulence, water vapor and more. After three years of data collection and analysis, the team agreed that the location had conditions on par with some of the best observatory sites in the world.

Gary Hill, the chief astronomer at the University of Texas’ McDonald Observatory who was not involved in the study, was particularly impressed by the site’s darkness. “If you go through the expense of building a telescope of that scale, you want to be able to have very good sensitivity to extremely faint objects,” says Hill. “Many sites that started off very dark increasingly have trouble with encroaching civilization and the stray light pollution that brings.” Since the mountain is far from major cities the area is likely to stay dark for a while. Overall, Hill thinks “it’s an extremely promising site.”

Because the site is so far inland, it avoids some—but not all—of the moisture that complicates the use of infrared telescopes. Water vapor absorbs infrared radiation which is “a real killer” for certain telescopes says Scott Paine an astrophysicist at the Harvard-Smithsonian Center for Astrophysics who was not involved in the research. For most of the year, he suspects water vapor wouldn’t be an issue but suspects it could post a challenge during wetter summer months.

Because all high-quality astronomical observatories are located in the Western Hemisphere, an observatory on the Tibetan Plateau could bridge a gap. If astronomers want to continually monitor an event happening over the course of a day, for example, they have to collaborate across observatories, like runners passing a baton. “Say there's a particularly unusual event, like two black holes merge or two neutron stars merge, where every data point counts as the Earth rotates,” says Patrick McCarthy, director of the NOIRLab, who was not involved in the work. “Right now, there are just gaps in time. There are parts of the earth that aren't covered. By putting an observatory in this longitude range in the middle of continental Asia, that gives us that extra time coverage that we don't have now.”

The world’s top observatories in Chile, Hawai’i and the Canary Islands stand to benefit from the uninterrupted monitoring that a site in the Eastern Hemisphere provides. “The international astronomical community is very collaborative because we're looking at the same sky,” says Deng. Though conduction and observations are being led by Chinese scientists, Deng says he’s looking forward to eventually opening the site at Lenghu to international astronomers.

Soon after the team completed their analysis, they broke ground on the observatory. “Construction is going on as we speak,” says Deng. The site already has a small working telescope and will soon host a 21-foot telescope, which will surpass the county’s 16-foot LAMOST telescope to become China’s biggest. The growing observatory is on track to become the next hub of Chinese astronomy, says Deng. The observations that they record over the next few years will help determine if the site is as promising as the initial assessment suggests. If so, Deng is hopeful that the site at Lenghu could be home to the next-generation giant Chinese telescope.

Chinese astronomers eye Tibetan Plateau site for observatory project


By Meghan Bartels - Senior Writer

Chinese astronomers hope to establish a major observatory program on the roof of the world, the Tibetan Plateau, with new research arguing for pristine observing conditions nestled in the uplands.

The analysis focuses on a study site near Lenghu Town in Qinghai Province at an altitude of more than 2.5 miles (4.2 kilometers) and some 1,900 miles (3,000 km) west of Beijing. In the paper, the scientists argue that three years of monitoring shows conditions on par with those at some of the most renowned scientific outposts on Earth. Moreover, making use of the site would fill a gap in scientists' existing global network of high-altitude, high-caliber observatory complexes, allowing for more reliable monitoring of phenomena that change rapidly, like supernovas. Right now, top-tier observatories cluster in the Western Hemisphere — think Maunakea in Hawaii, Cerro Paranal in Chile and La Palma in the Canary Islands.

"Finding a good site in China, spatially on the Tibetan Plateau, is essential to the development of astronomy and planetary science in China," co-author Fei He, an optics specialist at the Institute of Geology and Geophysics of the Chinese Academy of Sciences in Beijing, told Space.com in an email.

The initiative tracks with China's heavy focus on building new science and technology facilities around the world, Dean Cheng, an expert on Chinese military and space activities at the Heritage Foundation, a conservative public policy think tank based in Washington, D.C., told Space.com.

"Astronomy is a high priority," Cheng said. "Both inside and outside China, they are busily improving their space surveillance capabilities, space observation capabilities, but also their scientific capabilities as we've seen with their missions to Mars and the moon."

The site analyzed in the new research is located on the Tibetan Plateau but not in Tibet proper, which China invaded in 1959 and where tensions continue to run high. Qinghai Province is next door, but about a quarter of its population are Tibetan, according to China's government press agency Xinhua.

And while the research was only submitted this February, observatories are already in the works at the site, according to Xinhua. The news bureau announced in April 2020 that a Chinese university and the regional government had agreed to terms for the construction of the Wide Field Survey Telescope (WFST), a 2.5-meter optical telescope at the time scheduled to begin work in 2022.

Before focusing on the site near Lenghu Town, the scientists behind the new research set up equipment at three additional locations during early stages of the research, between 2016 and 2018. But Lenghu Town was a particularly appealing site, He wrote, and somewhat connected to the urbanized coast on the other side of the country.

Plus, local government officials invited the team in to conduct the analysis. "Lenghu has been known to have unusually clear sky to the community, and at the same time, Lenghu area has a spectacular landscape similar to Mars, therefore the local government wanted to develop tourist industry specialized in astronomy and planetary science," He wrote.

So He and his colleagues took to trekking out to the site, which is located on Saishiteng Mountain at an altitude of about 13,800 feet (4,200 meters), about 200 feet (60 m) higher than the Keck Observatory in Hawaii. The site's elevation is key: Earth's atmosphere causes blurring in astronomical observations and the higher a telescope's site is, the less atmosphere instruments must see through.

Other factors also appeal to the team from the new analysis. The sky is relatively dark, and Lenghu officials have already created regulations to keep background light low. According to 30 years' worth of weather records studied by the team, the site sees just 0.71 inches (18 millimeters) of precipitation a year and 3,500 hours of sunshine. And the team's analysis of factors like air stability, turbulence and water vapor, are also promising, according to the researchers

Of course, the elevation and remoteness that fosters such dark skies are also logistical challenges.

"Before the road reached the summit of Saishiteng Mountain, the necessary building materials and tools were carried to the site by a helicopter and the scientific devices were manually carried up to the mountain," He wrote. One team member saw wolves and thick snow was a regular challenge.

That's not likely to foil plans to build observatories. Currently, China is quite focused on construction on the Tibetan Plateau, and particularly in Tibet itself, which in addition to its own restiveness is a key strategic region given China's tensions with nuclear-armed India, Cheng noted.

"They're on top of the world at the top of the Himalayas," he said. "The Chinese are building massive infrastructure — roads, railways, air bases, military bases, camps — and moving in a lot of military equipment."

Between trips up the mountain, team members talked with local residents of Lenghu Town. While the authors noted that local officials were enthusiastic about the prospect of welcoming astronomy to the site, it's not clear whether residents agree.

He said that about 3,000 people live in the town, which is located about 50 miles (80 km) away from the analyzed site. "What we usually talked about is how the development of astronomy and planetary science at Lenghu could make their lives better," He wrote of conversations with residents.

"Scientific development will attract more tourists here and promote the development of local tourism, so they can make more money," He wrote. "During the night, when walking on the street, we also introduce the stars and planets to them and what kind of tourism can be developed. At the same time, we also talked about the protection of the dark sky which is essential to the development of the observatory, and they were happy to make sacrifices for it."

Some of those sacrifices are already in action. "If the local population were to grow with economic development, then control of light pollution could be lost," the authors wrote in the paper. But Lenghu leaders knew that going in and passed strict dark-sky protections in 2017 to avoid that threat — part of what has made the site so appealing for the researchers, they wrote.

And the result is stunning. "When you are on the summit of the mountain, you can see the fantastic Mars-like landscape of the Qaidam Basin during the day, and the magnificent and beautiful starry sky during the night," He wrote. "It was very memorable."

The research is described in a paper published Wednesday (Aug. 18) in the journal Nature.

Abstract
On Earth’s surface, there are only a handful of high-quality astronomical sites that meet the requirements for very large next-generation facilities. In the context of scientific opportunities in time-domain astronomy, a good site on the Tibetan Plateau will bridge the longitudinal gap between the known best sites1,2 (all in the Western Hemisphere). The Tibetan Plateau is the highest plateau on Earth, with an average elevation of over 4,000 metres, and thus potentially provides very good opportunities for astronomy and particle astrophysics3,4,5. Here we report the results of three years of monitoring of testing an area at a local summit on Saishiteng Mountain near Lenghu Town in Qinghai Province. The altitudes of the potential locations are between 4,200 and 4,500 metres. An area of over 100,000 square kilometres surrounding Lenghu Town has a lower altitude of below 3,000 metres, with an extremely arid climate and unusually clear local sky (day and night)6. Of the nights at the site, 70 per cent have clear, photometric conditions, with a median seeing of 0.75 arcseconds. The median night temperature variation is only 2.4 degrees Celsius, indicating very stable local surface air. The precipitable water vapour is lower than 2 millimetres for 55 per cent of the night.

Main

The geographic information of the site, Lenghu in Qinghai Province, is summarized in Methods and Extended Data Fig. 1. The main site parameters—including cloudiness and night-sky background brightness, air temperature, pressure, humidity, wind speed and direction, dust, precipitable water vapour (PWV), and, most importantly, seeing (using a differential image motion monitor (DIMM)7,8)—have been monitored starting at different times from March 2018 onwards (summarized in Extended Data Table 1). As DIMM seeing must be measured in the vicinity of a telescope project and at a similar height from the ground as the telescope, a 10-m tower was built to mount the DIMM. Shortly after the initial site reconnaissance, to start the site monitoring as soon as possible, the building materials and tools were carried to the site by a helicopter and the scientific devices were manually carried up to the mountain in September 2018, before the road reached the site. This could not have been accomplished without the great assistance from the local government of Lenghu Town. All the measurements and preliminary statistics of the raw data are updated daily and are available at http://lenghu.china-vo.org/index.html. Comprehensive comparisons of the key site characteristics of Lenghu with those of the other known best astronomical sites in the world are summarized in Table 1. A detailed analysis is given in the following.

Fossil fuel workers ready for a just transition, poll finds

By Natasha Bulowski, 
Local Journalism Initiative Reporter National Observer
Wed., July 14, 2021

A majority of Canadians working in fossil fuels are interested in switching to jobs in the net-zero economy, but are worried about being left behind, according to a new poll.

The poll, released Wednesday morning, was done by an oilpatch worker-led organization, Iron & Earth, in partnership with Abacus Data, and surveyed 300 fossil fuel workers across Canada from May 24 to June 11.

Ninety per cent of workers surveyed believe they could transition to at least one type of net-zero technology with 12 months or less of training, according to the poll results.

Edmonton-based machinist Stephen Buhler has worked in oil and gas for over 12 years and says we can’t afford to delay the transition away from fossil fuels any longer.

“Not making the transition means that a lot of workers like myself are going to be stuck with jobs that aren’t in demand the way that they were before,” he said.

Buhler is confident he can transition with little training. Because “whether it’s building a part for a pipeline or building a part for a wind turbine, it’s really no different for me,” he said, but acknowledged that for many workers, it won’t be so easy.

The poll also showed 61 per cent of workers worried about having to invest money into retraining, and 64 per cent were concerned with the time commitment involved.


Nearly 85 per cent of workers said they would participate in a paid training program of 10 days or less, with that number dropping to 70 per cent if they had to pay out of pocket.

“For the vast majority of other workers, taking on the financial burden of a year’s training, or even four years’ training … that’s a pretty tough pill to swallow,” said Buhler, adding the government should step up to help alleviate the financial burden of retraining.

Luisa Da Silva, executive director of Iron & Earth, agrees.

“The key here, really, is paid, rapid upskilling training for fossil fuel workers,” she said.

According to Iron & Earth’s calculations, Da Silva said, it would cost approximately $10,000 on average to rapidly upskill one worker, and to do the entire fossil fuel industry workforce would cost upwards of $5.5 billion.

Because many workers live in rural communities, Da Silva said it’s also vital to bring the training directly to those workers, so it is inclusive and accessible.

The data showed workers in the 45-plus age category were less confident in their ability to thrive in a net-zero economy than younger workers.

“It is definitely a little terrifying to be close to the end of your career, thinking about retirement, and all of a sudden, the entire world around you is going to be changing, and you’re told that the thing you were doing before is no longer needed or wanted,” said Buhler.

As a younger worker, Buhler said older workers should be given supports and noted they will be valuable for the short-term work needed to decommission and refurbish existing infrastructure.

Despite an overall high desire to switch to net zero and broad recognition of the threat of climate change, the poll found 60 per cent of workers worry they’ll be left behind in this transition without further training or career support.

“Until there is action by the government, which includes a just transition plan with paid training for fossil fuel workers, it’s understandable that a lot of workers may be hesitant,” said Da Silva.

Ultimately, it all boils down to jobs, said Ed Brost, who worked for Shell for 30 years before retiring to start his own consulting company.

“People need jobs, they need income, they have to take care of their families and their needs, and people are talking about changing your job … of course, it’s going to be apprehensive. I would be,” said Brost.

He said no one has to be left behind, but it’s up to our governments to show there is a path forward.

Iron & Earth is pushing for the federal government to support a national upskilling initiative so workers can be confident they won’t have to pay out of pocket for training, and it will be quick to make the switch.

Gil McGowan, president of the Alberta Federation of Labour (AFL), said coal transition policies the AFL helped create when Alberta began phasing out coal-fired power plants will serve as a valuable blueprint for the much larger transition away from oil and gas.


Wage top-ups for unemployment insurance, training vouchers for $12,000 and pension-bridging packages were all part of a transition package negotiated with the Alberta government, but McGowan said one thing missing from the coal transition package was a guarantee of employment.


Despite any shortcomings, he said the coal transition has been successful and much quicker than anticipated, lending hope to the idea that an oil and gas transition can follow suit.

“The thing is, the number of workers in coal is tiny compared to the number of people working in oil and gas,” said McGowan. “So scaling up this approach is going to be much more challenging.”

With over 30 years of experience in the oil and gas industry, Brost said transitioning will provide some immunity from boom-and-bust cycles, which, for younger workers especially, should be something to get excited about.

“I’ve been in the sector during good times and the bad, and it’s really scary when you know that the company you’re working for is going to cut the workforce by two or three or five per cent,” he said.

But workers need a just transition plan if they are to benefit from the long-term growth promised by renewable energy and green infrastructure, and McGowan said the Alberta government will continue to bury its head in the sand until “our federal government actually starts implementing policies instead of just talking about them.”

Natural Resources Canada spokesperson Ian Cameron said the government remains fully committed to helping workers “build the clean energy future we need.”



We have had great responses and feedback from workers who want to see themselves and other workers supported through the transition to net-zero. 

Some of the things we are hearing from fossil fuel workers include:

From a former oil and gas worker, in Newfoundland and Labrador: “It’s tough here right now. People are trying to save money, to put away what they can. A lot of people are out of work here, so the cost of retraining is a worry. People need to be retrained to transition but they may not be able to afford it on their own.”

From a worker in Medicine Hat: “I’ve already done four years of technical training and I have 15 years doing electrical work already. I want to work in the net-zero economy, but the biggest thing is now I have to go back and do another year or two of training on top of this. As a father and having a family it’s like, how do you afford all this? “

With the federal election underway, right now is a great opportunity for you to help fossil fuel industry workers be a part of shaping a just and prosperous transition  plan that policy makers will need once a government is  elected.

Classrooms in England need air filters and monitoring devices fitted to protect children from Covid-19 and avoid further disruption to their learning, school unions have told the education secretary, Gavin Williamson.

The seven unions – representing teachers, school leaders, administrative and support staff – have written to Williamson asking for “urgent action” to improve ventilation when schools reopen for the autumn term without any requirement for children to wear masks or be grouped in “bubbles”.


Lack of government Covid plan for English schools ‘unforgivable’, says report

The letter, backed by the Liberal Democrats, asks for air purification units to be installed to filter out the virus, as well as carbon dioxide monitors to measure airflow. It follows mounting evidence that coronavirus is transmitted primarily through airborne particles in enclosed spaces.

“There is a strong possibility of steeply increasing Covid cases in the autumn, with some children suffering from long Covid as a result. There are also concerns about a new wave of other respiratory diseases such as flu and RSV which are worse for children than Covid,” the letter warns.

“School staff, some of whom will not be double vaccinated, or are in a vulnerable group, are also in some cases still at risk of serious illness. Staff who are fully vaccinated are also still at risk of catching the virus and potentially developing long Covid, which is already afflicting tens of thousands of school staff.”

The group told Williamson it was “very concerned” that the Department for Education (DfE) had not provided any specific funding for schools to improve ventilation since January. The signatories include Unite, the National Association of Head Teachers, the Association of School and College Leaders, the NASUWT, the National Education Union, GMB and Unison

The DfE said: “We want to ensure schools are both safe and comfortable for students and staff – and good ventilation has consistently been part of government guidance. Areas where ventilation is poor should be proactively identified so that steps can be taken to improve fresh air flow if needed.”

The DfE and the Department for Health are running a £1.75m pilot scheme in Bradford to assess the most effective use of air purification technologies within schools.

Patrick Roach, the general secretary of the NASUWT teaching union, said a commitment by the government to fund improved ventilation would be “an extremely positive move. It would be reassuring to those working within our schools and be reassuring for many parents.”

Separately, a coalition of fire safety and education organisations have asked the government to mandate for sprinklers to be included in all new and refurbished school buildings in England.

The group, including the National Fire Chiefs Council and the Royal Institution of Chartered Surveyors, said the government’s latest plans would leave “the majority of schools exposed to fires”, with sprinklers only compulsory in boarding or special needs schools or in buildings over 11 metres in height.

The group said that in the five years to March 2020, firefighters attended fires at 1,467 primary schools and 834 secondary schools in England. Forty-seven primary and secondary school buildings were completely gutted and 230 others were seriously damaged.

Cambodia jails union leader for two years for ‘incitement’

Court hands maximum penalty to Rong Chhun who was arrested after raising concerns about land rights on the Cambodia-Vietnam border.

A Cambodian court has jailed prominent union leader Rong Chhun for two years – the maximum sentence – after finding him guilty of “incitement” over remarks he made about the Vietnam-Cambodia border last year.

Judge Li Sokha announced the decision during a brief hearing at the Phnom Penh Municipal Court on Wednesday that was attended by some international diplomats.

Activists Sar Kanika and Ton Mimol, who were also accused of incitement, were also found guilty and jailed for 20 months each.

The three, who have been in custody since their arrest a year ago, were also ordered to jointly pay $100,000 to the government’s border committee.

“It’s so disappointing. This is a serious punishment, and the verdict did not render justice to my three clients,” said lawyer Sam Sokong, who added that Rong Chhun planned to appeal the ruling.

Rong Chhun was arrested on July 31 last year after accusing the government of “irregularities” in the demarcation of its eastern border with Vietnam, and some villagers had lost land as a result. The border is a sensitive issue fuelled by strong anti-Vietnamese feelings among some Cambodians.

Human rights groups have condemned the arrest of Rong Chhun, a veteran labour rights activist and the head of the Cambodian Confederation of Unions, and called for his release.

Cambodia’s government under long-term leader Hun Sen has cracked down on the opposition and critical voices, outlawing the opposition party in the run-up to the 2018 elections and putting its leader on trial for treason.

A 2020 report from the United Nations human rights office found “civic and democratic space in Cambodia had been shrinking”, and the work of human rights and civil society organisations subjected to “undue interference, intimidation or harassment”.

Licadho, a human rights group, says 19 activists, artists and human rights defenders were arrested in the weeks following Rong Chhun’s arrest. Sar Kanika was detained a month after Rong Chhun at a peaceful rally calling for his release, while Ton Mimol was picked up at an October rally outside the Chinese embassy.

Rong Chhun denied the charges against him when he was put on trial in January, and his supporters were angry about Wednesday’s court ruling.

“The court’s decision to sentence Rong Chhun today is a threat to younger generations … to stop thinking about the nation’s problems and social issues,” Ouk Chhayavy, president of the Cambodia Independent Teachers’ Association, told reporters outside the court.

China’s crackdown on its workplace drinking culture is a problem for the world’s largest liquor company

WORK IS THE CURSE OF THE DRINKING CLASS

DRINK IS THE CURSE OF THE WORKING CLASS

China's quest for office sobriety is not going down smoothly for Kweichow Moutai, the Chinese liquor giant and the world’s largest liquor company by market capitalization.

The stock price for Kweichow Moutai has fallen nearly 10% since last Tuesday when China’s top anti-corruption watchdog, the Central Commission for Discipline Inspection (CCDI), criticized drinking behaviors in Chinese offices.

The CCDI issued the statement on Aug. 10 in response to online furor regarding an account of a rape case at Chinese tech giant Alibaba. In the incident, a female employee at Alibaba reported that her boss, Wang Chengwen, forced her to go on a business trip in late July, pressured her to drink to the point where she blacked out, and then raped her, the employee wrote on an internal company message board.

The employee’s account went viral on Chinese social media, prompting Alibaba to fire the employee. (In an initial probe, local authorities in China’s eastern city of Jinan described the case as “forcible indecency” and not rape, but their investigation is still ongoing.)

But the case sparked a broader backlash to drinking culture at Chinese companies.

In a note to his employees, Alibaba chief executive Daniel Zhang vowed to rectify an “ugly forced drinking culture” that was plaguing the company. In the Aug. 10 statement, the CCDI said that it would strengthen oversight of Chinese companies to combat toxic work cultures in which employees are pressured to drink.

But if and how regulators will do that remains unclear. Pressuring others to drink is a behavior that is deeply entrenched in China's business culture. It is seen by many as essential to striking deals, hosting banquets, or even conducting a job interview.

"The million dollar question is, does this mean there's going to be a lot of regulation that will follow [the CCDI statement]… Or is this problem with irresponsible drinking something [that China will] address over time," says Euan McLeish, a managing director and senior equity analyst at Sanford C. Bernstein in Hong Kong. McLeish explained that potential regulatory measures could include increased taxes on alcohol, education campaigns to limit drinking, and giving more power to servers to cut off drunk customers. “[This uncertainty] is why the liquor market is pretty jumpy at the moment.”

The share price for Kweichow Moutai competitor Wuliangye is similarly down nearly 8% since the CCDI announcement.

Kweichow Moutai is known for its expensive baijiu, a clear, strong liquor that is often distilled using sorghum or other grains and was famously a drink of choice for China’s founder Mao Zedong. Kweichow Moutai’s elite status has made it a symbol of wealth and power as well as a mainstay at business banquets across the country.

"It's not something that a business would serve day-to-day," says McLeish. "But it still is consumed very much on business occasions, when [businesses] are celebrating or there's someone they are trying to impress."

Kweichow Moutai's popularity has made it one of China's largest companies with a market capitalization of over $313 billion, nearly three times the size of Belgian alcohol giant Anheuser-Busch InBev, and powerful enough to help prop up the finances and fund public infrastructure of Guizhou province, the underdeveloped province in southern China where Kweichow Moutai is headquartered.

Moutai's size and status within China may make the company relatively immune to the CCDI's warning about drinking culture. The company withstood a regulatory crackdown once before, notes McLeish. In the early 2010s, Chinese President Xi Jinping launched an anti-corruption campaign that targeted the lavish spending habits of public officials.

But Brock Silvers, chief investment officer at Kaiyuan Capital in Hong Kong, says that Beijing's latest campaign against drinking culture could spell trouble for Kweichow Moutai, given that Chinese authorities are currently cracking down on the power of many of the country's largest firms.

“In this atmosphere, any regulatory attention will be taken seriously. China’s recent crackdown on workplace alcohol culture is thus an important matter for [Kweichow Moutai],” says Silvers. “It’s likely to affect the company’s bottom line and perhaps even scare investors sober.”

NYK assists in Crimson Polaris oil cleanup operations

NYK Line, as the charterer of the Crimson Polaris, has sent teams to assist the cleanup of the oil spill the wrecked wood chip carrier caused off the coast of Hachinohe, Japan last week.

The company said it has dispatched the first group of 10 people for two days and one night and plans to continue sending more personnel to help with the cleanup efforts.

COLLECTING GOODS FOR INSURANCE MONEY YOU SAY

“From the standpoint of being involved in this accident as a charterer, we have decided to first recruit workers to clean the cargo washed ashore on the beach and dispatch them to the site.

The 49,500 dwt ship broke apart and started spilling oil last Thursday about 4 km off Japan after running aground at the Hachinohe Port a day earlier. The MI-DAS Line-owned vessel had about 1,550 metric tonnes of heavy oil and about 130 metric tonnes of diesel oil onboard.

The oil spill, which spread around 24 km north of the coastline, reached Japanese shores last Friday. The extent of the environmental impact remains unclear, but Japanese media reported that several fishing grounds have been contaminated. Investigations into the accident are ongoing.
