Dangerous Mekong River pollution blamed on lawless mining in Myanmar | Environment News

Houayxay, Laos – Fishing went effectively at present for Khon, a Laotian fisherman, who lives in a floating home constructed from plastic drums, scrap metallic and wooden on the Mekong River.

“I caught two catfish,” the 52-year-old tells Al Jazeera proudly, lifting his catch for inspection.

Khon’s easy houseboat accommodates all he must stay on this mighty river: A number of metallic pots, a hearth to prepare dinner meals on and to maintain heat by at evening, in addition to some nets and some garments.

What Khon doesn’t at all times have is fish.

“There are days after I catch nothing. It’s irritating,” he stated.

“The water ranges change on a regular basis due to the dams. And now they are saying the river is polluted, too. Up there in Myanmar, they dig within the mountains. Mines, or one thing like that. And all that poisonous stuff finally ends up right here,” he provides.

Khon lives in Laos’s northwestern Bokeo province on one of the crucial scenic stretches of the Mekong River because it meanders via the center of the Golden Triangle – the borderland shared by Laos, Thailand and Myanmar.

This distant area has lengthy been notorious for drug manufacturing and trafficking.

Now it’s caught up within the world scramble for gold and uncommon earth minerals, essential for the manufacturing of recent applied sciences and utilized in all the things from smartphones to electrical automobiles.

Over the previous yr, rivers on this area, such because the Ruak, Sai and Kok – all tributaries of the Mekong – have proven irregular ranges of arsenic, lead, nickel and manganese, in response to Thailand’s Air pollution Management Division.

Arsenic, particularly, has exceeded World Well being Group security limits, prompting well being warnings for riverside communities.

These tributaries feed instantly into the Mekong and contamination has unfold to elements of the river’s mainstream. The results have been noticed in Laos, prompting the Mekong River Fee to declare the scenario “reasonably severe”.

“Current official water high quality testing clearly signifies that the Mekong River on the Thai-Lao border is contaminated with arsenic,” Pianporn Deetes, Southeast Asia campaigns director for the advocacy group Worldwide Rivers, advised Al Jazeera.

“That is alarming and simply the primary chapter of the disaster, if the mining continues,” Pianporn stated.

“Fishermen have just lately caught diseased, younger catfish. It is a matter of regional public well being, and it wants pressing motion from governments,” she added.

The supply of the heavy metals contamination is believed to be upriver in Myanmar’s Shan State, the place dozens of unregulated mines have sprung up because the seek for uncommon earth minerals intensifies globally.

Zachary Abuza, a professor on the Nationwide Struggle Faculty in Washington and an professional on Southeast Asia, stated not less than a dozen, and presumably as many as 20, mines centered on gold and uncommon earth extraction have been established in southern Shan State over the previous yr alone.

Myanmar is now 4 years right into a civil battle and lawlessness reigns within the border space, which is held by two highly effective ethnic armed teams: the Restoration Council of Shan State (RCSS) and the United Wa State Military (UWSA).

Myanmar’s army authorities has “no actual management”, Abuza stated, aside from holding Tachileik city, the area’s primary border crossing between Thailand and Myanmar.

Neither the RCSS nor the UWSA are “combating the junta”, he stated, explaining how each are busy enriching themselves from the chaos within the area and the push to open mines.

“On this vacuum, mining has exploded – possible with Chinese language merchants concerned. The army in Naypyidaw can’t problem permits or implement environmental guidelines, however they nonetheless take their share of the earnings,” Abuza stated.

‘Alarming decline’

Air pollution from mining isn’t the Mekong River’s solely ailment.

For years, the well being of the river has been degraded by a rising chain of hydropower dams which have drastically altered its pure rhythm and ecology.

Within the Mekong’s higher reaches, inside China, nearly a dozen big hydropower dams have been constructed, together with the Xiaowan and Nuozhadu dams, that are stated to be able to holding again an enormous quantity of the river’s move.

Additional downstream, Laos has staked its financial future on hydropower.

In keeping with the Mekong Dam Monitor, which is hosted by the Stimson Centre suppose tank in Washington, DC, not less than 75 dams at the moment are operational on the Mekong’s tributaries, and two in Laos – Xayaburi and Don Sahong – are instantly on the mainstream river.

As a rule, hydropower is a cleaner various to coal.

However the rush to dam the Mekong is driving one other kind of environmental disaster.

In keeping with WWF and the Mekong River Fee, the Mekong River basin as soon as supported about 60 million folks and offered as much as 25 p.c of the world’s freshwater fish catch.

At this time, one in 5 fish species within the Mekong is liable to extinction, and the river’s sediment and nutrient flows have been severely diminished, as documented in a 2023–2024 Mekong Dam Monitor report and analysis by Worldwide Rivers.

“The alarming decline in fish populations within the Mekong is an pressing wake-up name for motion to avoid wasting these extraordinary – and terribly necessary – species, which underpin not solely the area’s societies and economies but additionally the well being of the Mekong’s freshwater ecosystems,” the WWF’s Asia Pacific Regional Director Lan Mercado stated on the launch of a 2024 report titled The Mekong’s Forgotten Fishes.

In Houayxay, the capital of Bokeo province, the markets appeared largely absent of fish throughout a latest go to.

At Kad Wang View, the city’s primary market, the fish stalls had been almost abandoned.

“Possibly this afternoon, or perhaps tomorrow,” stated Mali, a vendor in her 60s. In entrance of her, Mali had organized her small inventory of fish in a circle, maybe hoping to make the show look fuller for potential clients.

At one other market, Sydonemy, simply outdoors Houayxay city, the story was the identical. The fish stalls had been naked.

“Typically the fish come, generally they don’t. We simply wait,” one other vendor stated.

“There was once big fish right here,” recalled Vilasai, 53, who comes from a fishing household however now works as a taxi driver.

“Now the river provides us little. Even the water for irrigation – individuals are scared to make use of it. Nobody is aware of if it’s nonetheless clear,” he advised Al Jazeera, referring to the air pollution from Myanmar’s mines.

‘The river was once predictable’

Ian G Baird, professor of geography and Southeast Asian research on the College of Wisconsin–Madison, stated upstream dams – particularly these in China – have had severe downstream results in northern Thailand and Laos.

“The ecosystem and the lives that rely on the river developed to adapt to particular hydrological situations,” Baird advised Al Jazeera.

“However for the reason that dams had been constructed, these situations have modified dramatically. There at the moment are fast water stage fluctuations within the dry season, which was once uncommon, and this has unfavourable impacts on each the river and the folks,” he stated.

One other main impact is the reversal of the river’s pure cycle.

“Now there’s extra water within the dry season and fewer through the wet season. That reduces flooding and the helpful ecological results of the annual flood pulse,” Baird defined.

“The dams maintain water through the wet season and launch it within the dry season to maximise power output and earnings. However that additionally kills seasonally flooded forests and disrupts the river’s ecological perform,” he stated.

Bun Chan, 45, lives together with his spouse Nanna Kuhd, 40, on a floating home close to Houayxay. He fishes whereas his spouse sells no matter he catches on the native market.

On a latest morning, he forged his internet repeatedly – however for nothing.

“Seems like I received’t catch something at present,” Bun Chan advised Al Jazeera as he pulled up his empty internet.

“The opposite day I caught a couple of, however we didn’t promote them. We’re conserving them in cages within the water, so not less than we have now one thing to eat if I don’t catch extra,” he stated.

Hom Phan has been a fisherman on the Mekong his complete life.

He steers his picket boat throughout the river, following a route he is aware of by intuition. In some elements of the river, the present is powerful sufficient now to pull all the things beneath, the 67-year-old says.

Throughout him, the silence is damaged solely by the chug of his small outboard engine and the calls of distant birds.

“The river was once predictable. Now we don’t know when it’ll rise or fall,” Hom Phan stated.

“Fish can’t discover their spawning grounds. They’re disappearing. And we’d too, if nothing adjustments,” he advised Al Jazeera.

Night approaches in Houayxay, and Khon, the fisherman, rolls up his nets and prepares dinner in his floating house.

As he waits for the hearth to catch to prepare dinner a meal, he quietly contemplates the good river he lives on.

Regardless of the dams in China, the air pollution from mines in neighbouring Myanmar, and the rising problem in touchdown the catch he depends on to outlive, Khon was outwardly serene as he thought of his subsequent day of fishing.

Together with his eyes fastened on the waters that flowed deeply beneath his house, he stated with a smile: “We attempt once more tomorrow.”
