On Son Island in Vietnam’s Mekong Delta, Le Trung Tin scatters fish feed into his ponds, the place dozens of snakehead fish leap by the floor in synchronised bursts. “I taught them how to try this,” he says proudly, tossing one other handful of feed at his fish.
The scene seems to be idyllic, however Le’s fish farm is a reluctant response to an escalating disaster. For many years, he made his dwelling fishing the Hau River, a distributary of the Mekong. However lately, plastic waste clogged his nets and strangled the fish. “I had no selection however to cease,” he says. “Every thing was tangled – trash, nets, even the fish themselves. It was hopeless.”
Now, Le depends on enclosed ponds utilizing filtered water to maintain his fish alive. “I constructed this ecological surroundings freed from plastic waste, chemical spills and [protected it from] excessive climate,” he says.
Le’s expertise displays the broader challenges going through the Mekong. Stretching over 4,300 kilometres from the Tibetan Plateau to the South China Sea, the river helps almost 70 million folks and among the world’s most biodiverse ecosystems.
But, it is likely one of the most plastic-polluted rivers on this planet and among the many 10 rivers in Asia that carry the overwhelming majority of plastic to the ocean. The Mekong dumps – by some estimates – tens of hundreds of tonnes every year into the ocean, with plastic waste accumulating alongside its banks, tributaries and lakes.
Plastic enters the Mekong in myriad methods – agricultural runoff, unregulated dumping and a flood of single-use packaging from upstream nations like China and Myanmar. It accumulates in hotspots like Tonle Sap Lake in Cambodia and the wetlands of Vietnam’s Mekong Delta, the place this plastic waste threatens biodiversity, meals safety and human well being.
The unchecked proliferation of single-use plastics, mixed with a scarcity of waste administration infrastructure throughout the area, has resulted in widespread mismanagement of plastic waste – a lot of which is neither recycled, incinerated nor correctly disposed in landfills.
Vietnam, usually ranked because the world’s fourth-largest contributor of mismanaged plastic waste, additionally accounts for a major share of marine plastic particles, highlighting the nation’s wrestle to deal with the disaster successfully.
Addressing the Mekong’s plastic air pollution disaster would require coordinated efforts from regional governments and transboundary organisations, nonetheless specialists say a long-lasting answer requires a daring international settlement limiting plastic use and manufacturing, mixed with enforceable regional insurance policies.

It’s unjust that those that bear the best burden of plastic air pollution are being denied the chance to forge an answer amongst themselves by these profiteering off the unregulated manufacturing and consumption of plastic.

A world disaster: Will the plastics treaty ship?
Hopes have been excessive as nationwide negotiators gathered in Busan, South Korea, to finalise the International Plastics Treaty – an bold UN effort aimed toward tackling the worldwide plastic air pollution disaster.
Nonetheless, the talks have been adjourned earlier this month with out settlement, leaving campaigners pissed off of their push for the treaty to deal with each ends of the disaster: limiting plastic manufacturing and bettering international waste-management programs.
On Sunday 1 December, the ultimate day of the summit, Eirik Lindebjerg, international plastics coverage lead for WWF, stated governments have been “no nearer to agreeing on an answer to the worsening plastic disaster.”
“For too lengthy, a small minority of states have held the negotiation course of hostage. It’s abundantly clear that these nations don’t have any intention of discovering a significant answer to this disaster,” he continued in a press launch.
“It’s unjust that those that bear the best burden of plastic air pollution are being denied the chance to forge an answer amongst themselves by these profiteering off the unregulated manufacturing and consumption of plastic.”
Critics additionally level out that earlier international agreements to resolve environmental crises, equivalent to local weather change and biodiversity loss, have fallen in need of their targets as a consequence of weak enforcement mechanisms and the affect of highly effective business lobbying teams.
Plastic manufacturing has doubled over the previous 20 years, with over 400 million tonnes produced yearly. Single-use plastics, which make up half of this whole, are notably problematic, accounting for a good portion of the waste clogging rivers just like the Mekong. Whereas technological options like recycling and waste-to-energy vegetation are sometimes advocated by business, their affect pales compared to the size of manufacturing.
The United Nations Surroundings Programme (UNEP) has warned that plastic air pollution may triple by 2040 with out drastic motion.
“The worth for inaction is much larger than wasted time, it places each planetary and human well being on the road and units us up for a situation the place ambition may diminish over time,” says Erin Simon, vp and head of plastic waste and enterprise with WWF. “We are able to’t again down on delivering a legally binding textual content that lastly places us on a course to eradicate plastic air pollution,” he added.
Dialogue Earth visited 4 plastic-waste hotspots alongside the decrease reaches of the Mekong – Chiang Saen in Thailand, Phnom Penh and Tonle Sap Lake in Cambodia and Vietnam’s Mekong Delta.
These websites showcase the issues the plastics treaty wants to deal with: waste from newly produced plastic, the damaging affect of plastic waste on native folks and the transnational nature of the issue.
Chiang Saen, Thailand: The place the Mekong’s plastic drawback peaks
In northern Thailand, the Mekong flows previous Chiang Saen close to the Golden Triangle, the place Thailand, Myanmar and Laos converge. Right here, plastic waste collects in rising heaps alongside the riverbanks.
The particles – meals wrappers, plastic bottles and fishing nets – has floated downstream from upstream nations like China and Myanmar, clogging tributaries just like the Ruak River.
“Generally it feels just like the waste by no means ends,” says Poonyawee Srisantear, who manages a neighborhood elephant camp. Mahouts (elephant keepers) on the camp commonly accumulate garbage from the riverbanks to guard their elephants. “The odor of meals clings to the plastic and elephants usually mistake it for one thing to eat,” she explains. “After they swallow it, it may be life-threatening to them.”
Though plastic waste is seen alongside the Mekong’s banks, quantitative info stays scarce. Lately, worldwide organisations have tried to quantify the size of the issue.
Thailand, like many Mekong nations, additionally struggles with insufficient waste administration programs, which exacerbate the issue. Over 150 plastic-waste hotspots have been recognized throughout the nation. A 2023 research detected near 1,000 official and unofficial waste websites throughout Southeast Asia, almost a fifth of which have been positioned inside 200m of a waterway. Virtually half of those have been within the 5 Mekong nations of Myanmar, Cambodia, Laos, Thailand and Vietnam.
Chiang Saen can be the location of one of many Mekong River Fee’s (MRC) upcoming video monitoring stations, a part of a broader initiative to trace plastic flows throughout the basin.
The MRC serves as an intergovernmental advisory physique and the video monitoring system dovetails with its new protocols for riverine microplastic monitoring; the primary tips standardising water well being monitoring throughout the decrease Mekong basin.
“We’d like extra [and better] information to drive coverage change,” says Phan Nam Lengthy, a water high quality officer with the MRC. “With out info on the size of the issue, we can’t create efficient options.”
Critics, nonetheless, argue that such monitoring efforts fall in need of addressing the underlying drawback, partially as a result of MRC’s restricted advisory position to the area’s governments.
“It’s tremendous for the MRC to watch. Sure, the extra info, the higher. However that may’t be the one factor the MRC or the Mekong nations do,” says Niwat Roykaew, also called Kru Thi (instructor in Thai), an environmental activist, who based the Mekong College.
“We are able to see how the rubbish impacts the river. We are able to see how the rubbish impacts these depending on the river. That’s sufficient info for us to start to behave.”
Niwat desires to see a basin-wide accountability framework to sort out plastic air pollution. However with no settlement from the UN in Busan, he questions whether or not the Mekong area will have the ability to overcome its personal divisions to determine a unified method.
“All of the nations that share the Mekong River should share the duty,” he says. “Plastic is choking the river and the results have an effect on us all – from the fish we eat to the water we drink.”
Latest research performed alongside the riverside close to Niwat’s college underline his level.
“We’re hooked on plastics, now greater than ever,” says Panate Manomaivibool, an assistant professor at Thailand’s Burapha College. Over the course of a 12 months, ending in July 2022, his crew collected 2,650 giant waste samples from the waters across the Golden Triangle. He provides: “In comparison with the size of the issue, makes an attempt to repair it are tiny.”
Panate’s analysis decided that 91 per cent of the waste was plastic, with labels indicating round 30 per cent originated in Myanmar and almost 20 per cent in China, underscoring the transboundary nature of the problem. “Plastic air pollution has already contaminated our meals chain and all life within the Mekong,” he warns.
Panate tells Dialogue Earth he tries “to be optimistic that we’re not but on the irreversible turning level”, however fears the area’s habit to plastic might be laborious to interrupt.
“We’re the primary era going through this drawback on this scale. Our ancestors, even our dad and mom, have been by no means uncovered to this stage of plastic air pollution,” he says. “With out another, our nations will at all times select to make use of the most affordable, best possibility. For now, that is still plastic.”
The Thai authorities has taken motion by saying a ban on plastic waste imports from 2025, a transfer impressed by China’s 2018 restrictions, which redirected international waste to nations equivalent to Vietnam, Malaysia and Thailand itself. But home plastic consumption continues to rise.
“The extra folks there are, the extra the town develops, the financial system grows and the usage of plastic will increase,” says Saksan Chuamuangpan, director of Chiang Saen’s Public Well being Division.
Waste manufacturing within the district has skyrocketed from two tonnes per day twenty years in the past to fifteen tonnes at the moment, he says, and warns a joint effort is required.
Tonle Sap Lake: Cambodia’s beating coronary heart
In Cambodia, Tonle Sap Lake – a significant freshwater fishery for Southeast Asia – is more and more choked by plastic waste. Every monsoon season, the Tonle Sap River reverses move, carrying waste upstream into the lake. This cycle has made the survival of the lake’s ecosystems ever extra unsure.
Since assuming the position of Cambodia’s surroundings minister final 12 months, Eang Sophalleth has made addressing plastic air pollution a precedence. As a part of a nationwide anti-plastics marketing campaign he has known as on half of Cambodia’s 17 million inhabitants to cut back their use of plastics.
“Plastic is our primary enemy,” he stated on the September launch of the marketing campaign.
Cambodia additionally joined the International Plastic Motion Partnership final 12 months and signed an settlement with Laos to sort out cross-border plastic air pollution. However the focus has been on altering public notion and plastic habits, with little point out of plastic producers or waste administration enhancements. Eang says solely when plastic discount targets are met, will a significant clean-up of Tonle Sap Lake, the nation’s foremost supply of protein, happen. “There’s no level in cleansing if we’re throwing away greater than we clear up,” he stated.
Because it stands, although, a lot of the plastic continues to build up in fishing nets and alongside the shorelines, with little proof of progress on waste discount.
In Kampong Phluk, a fishing village on Tonle Sap Lake, plastic waste disrupts day by day life for native communities. Sophal Sea, director of the NGO Bambooshoot, says the particles is damaging livelihoods. “The nets get tangled, motors break down and fish shares are declining,” he says.
Welcoming the federal government’s obvious deal with plastic, he provides: “That is the primary time I’ve heard authorities leaders promise that form of help.” Nonetheless, he confused the necessity for political help and laws to deal with the systemic points fuelling the disaster and to wean Cambodia off what he described as its “trash tradition”.
Plastic disposal choices are scarce in villages surrounding the lake, main residents to dump waste straight into the water.
“Most individuals don’t know how you can get rid of their waste correctly. They only throw it in every single place,” says Srey Toch, a litter picker with River Ocean Cleanup who has joined Sophal and a bunch of volunteers to gather garbage on the confluence of the Tonle Sap and Mekong rivers.
Srey Toch’s observations are corroborated by Sovann Nou, River Ocean Cleanup’s govt director, who attributes the issue to insufficient family and industrial waste administration, mixed with restricted consciousness amongst the general public relating to the affect plastic waste has.
Strolling alongside the riverbank, he stops to carry up among the particles: plastic tarps, bottles and tyres. At one level he pauses to select up a useless turtle mendacity among the many waste – its dying a stark reminder of the toll plastic air pollution takes on wildlife.
Because the Mekong flows south previous Phnom Penh towards Vietnam, Eang expressed hope that different upstream nations will comply with Cambodia’s lead in starting to take steps to sort out plastic air pollution. “If we clear up plastics, downstream communities like Vietnam might be grateful. We’ll all profit,” he stated.
Can Tho: The place the Mekong meets the ocean
In Vietnam’s Mekong Delta, the river followers out into an enormous community of tributaries and wetlands supporting hundreds of thousands of individuals by farming and fishing. Often called Vietnam’s “rice bowl”, this fertile area can be closely impacted by plastic air pollution, with a lot of the waste from upstream deposited in its waterways and rice fields.
By the point the Mekong reaches Vietnam’s Delta, the river carries the amassed waste of its 4,300km journey.
“Most inland waste reaches the river by canals, particularly throughout annual flooding,” says Nguyen Xuan Hoang, a researcher from Can Tho College’s Faculty of Surroundings and Pure Assets. “Most of this plastic isn’t from Vietnam, however because the basin’s lowest level, we undergo probably the most.”
Again on Son Island, on the Hau River, Le has skilled this struggling firsthand, however switching to fish farming in enclosed ponds seems to have paid off. He notes a discount in fish deaths, mixed with a rise in income in comparison with his earlier ventures within the plastic-choked waters of the river.
“Residing in concord with nature is crucial for fish farming, however it’s turning into more durable within the delta,” he provides, acknowledging the extra effort required to protect his livelihood from the worsening environmental challenges.
For farmers like Trung Tin, in close by Thoi Lai District, the air pollution is inconceivable to disregard. On account of a scarcity of plastic waste disposal choices, farmers usually go away fertiliser and pesticide bottles in fields, fearing the discharge of poisons in the event that they burn them. Rain washes these bottles and residues into the canals, polluting the delta’s waterways.
Based on Trung, who has farmed rice for over 20 years, “the local weather now isn’t straightforward”. “The soil has much less vitamin, and we should defend crops, even when it means utilizing extra chemical compounds.” Seeing discarded bottles within the river, he provides: “It’s scary to consider what’s within the fish we eat.”
Cong Thuan Nguyen, one other researcher at Can Tho College, confirmed that agricultural waste from rice farms is a major supply of air pollution. “We’re nonetheless attempting to grasp the complete scale. The extra we be taught, the extra the issue grows,” he tells Dialogue Earth.
In 2019, the Vietnamese authorities appeared to take steps to fight the plastic disaster, by saying a ban on plastic waste imports beginning in 2025. In 2022, it carried out the Prolonged Producer Duty coverage, requiring corporations to handle the recycling of their merchandise and packaging to cut back waste and promote sustainability.
Regardless of these commitments, the nation was the world’s fourth largest importer of plastic waste in 2022, including to its waste administration struggles. A major proportion – as much as 30 per cent – of this imported plastic leaks into rivers and waterways, together with the Mekong Delta, usually carried by runoff or untreated wastewater.
Because the 2025 deadline for plastic waste imports approaches, Vietnam’s potential to implement the ban and transition to different recycling or disposal programs might be important to decreasing the plastic burden on the Mekong Delta and safeguarding the livelihoods it sustains.
Amongst these challenges is the necessity for larger readability from Vietnam, whose stance on INC-5 seems to straddle each nationwide financial pursuits, notably within the plastics business, and broader commitments to addressing international plastic air pollution. Shifting ahead, Vietnam might want to prioritise one over the opposite to display its dedication to tangible motion.
Thailand, in the meantime, has expressed help for a legally binding worldwide settlement to cut back plastic waste and mitigate its environmental and well being impacts. Nonetheless, its heavy reliance on single-use plastics and restricted progress in addressing home waste administration challenges increase questions on how successfully these commitments might be carried out.
Equally, whereas Cambodia has emphasised the significance of efficient implementation mechanisms, together with the institution of nationwide committees beneath Article 8 of the treaty, its capability to ship on these goals stays unsure. The nation’s reliance on worldwide collaboration, capacity-building and technical help underscores gaps in its present infrastructure to sort out plastic air pollution independently.
In the meantime, grassroots efforts are working to scrub the Mekong Delta regardless of overwhelming odds. Waste-collecting boats commonly navigate canals to take away particles and NGOs run instructional campaigns to cut back dependency on single-use plastic.
The Mekong’s plastic disaster is not only a regional difficulty; it’s emblematic of a worldwide failure to handle waste sustainably. Because the river carries tens of hundreds of tonnes of plastic waste into the South China Sea every year, its plight underscores the urgency of options at each stage – native, regional and international.
“We’ve got not but reached the summit of our efforts,” INC chair Luis Vayas stated on Sunday, on the finish of seven days of negotiation that concluded with out consensus. The assembly was adjourned, with plans to reconvene subsequent 12 months, leaving questions on how quickly tangible actions may handle urgent points like plastic air pollution within the Mekong Delta.
With out intervention, the Mekong will proceed offloading plastic into the South China Sea. From the primary indicators of plastic air pollution within the Golden Triangle to the plastic-clogged canals of the delta, the river’s journey highlights the pressing want for coordinated, cross-border motion to guard each the river and the hundreds of thousands who rely on it.
