The Chao Phraya begins on the confluence of the Ping and Nan rivers, which meet in Nakhon Sawan province within the coronary heart of Thailand. Though the river’s waters have already traveled half of the nation’s size by this level, it’s nonetheless comparatively clear, flanked by villages and farms.
The encompassing land is good for rising rice due to the river’s annual floods, which include the monsoon from Might to October and supply an ample provide of water and vitamins. In 2012, round 45 p.c of land within the Chao Phraya river basin was used for rice farming. Fruit orchards are additionally frequent.
However plastics already make an look up right here. The farms themselves are one oblique supply – the fabric is used extensively in agriculture throughout Thailand.

Floods convey plastic to historical capital
The floods that convey water and vitamins to crops alongside the Chao Phraya additionally draw plastic into the river.
South of Nakhon Sawan, the Chao Phraya flows via the traditional metropolis of Ayutthaya, which was the capital of Thailand till 1767. Constructed on the level the place two different rivers be part of the Chao Phraya, town is crisscrossed with canals, and conventional methods of life listed here are carefully linked to the water. Seasonal flooding is predicted, with properties alongside the waterways constructed on stilts to accommodate the upper water ranges. However local weather change and a variety of different elements is intensifying rainfall, and extreme flooding is a rising downside within the metropolis.
Ratimaporn Pakorn is a 23-year-old boat driver in Ayutthaya. Her residence was flooded in 2021 after unusually heavy rainfall. “The world floods almost yearly, however the extent of it varies. Final 12 months, the water got here all the best way as much as my calves,” she remembers.
Ratimaporn Pakorn drives her household’s boat on the Chao Phraya at Ayutthaya. Behind her a tug pulls a barge loaded with sand. Sand is extracted at quite a few factors alongside the river, which may very well be lowering the watershed’s capability to take up floodwaters. (Picture: Mailee Osten-Tan / The Third Pole)

As a UNESCO World Heritage Web site, the traditional capital attracts vacationers from across the globe, a lot of whom take boat excursions to view its well-known temples. Ratimaporn depends on these vacationers to make a dwelling.
“It’s soiled,” says Ratimaporn, noting that plastic will be seen floating within the river, the place it typically clogs her propellers. She worries that it will impression vacationers’ perceptions of town.

Because the Chao Phraya snakes via densely populated central Thailand and on to the nation’s modern-day capital, Bangkok, it’s typically handled as a catch-all waste disposal unit.
Very like Ayutthaya, Bangkok grew from a settlement constructed on canals that borrowed the waters of the Chao Phraya to type handy transport routes. These canals, often known as khlongs in Thai, stay a major function in immediately’s megacity, which has over a thousand, lined with settlements and residential to over 23,500 primarily low-income households. Many are choked with plastic.
Sira Leepipattanawit is a group chief who grew up on the Bangkok Yai canal. Most of the communities alongside Bangkok’s canals are onerous to achieve by highway, making it troublesome to entry municipal providers. Throwing waste instantly into the water is an previous behavior. Though that is now formally unlawful, and folks may very well be fined, Sira explains that it’s nearly unattainable to determine the culprits. Homes are sometimes located instantly above the water, and residents “can simply open their window and plop their trash bag into the water when nobody’s trying – at evening, for instance”, he says.
This used to only be a simple approach to take care of family waste. However within the previous days, this waste was natural. At this time, on a regular basis gadgets come wrapped in plastic – not simply in Bangkok, however throughout Thailand.

On a Monday afternoon on the Bangkok Yai canal, vacationers cruise round on long-tail boats whereas youngsters swim amongst previous flip-flops and polystyrene fragments. Nonetheless, the water right here is at the very least comparatively clear. On the opposite aspect of town, on the Lat Phrao canal, the scene is totally different. The water has a tar-like consistency and a putrid stench envelops the entire space.
“It’s from the wastewater and all of the junk,” explains Samnieng Bonlu, a 66-year-old resident who has lived on the Lat Phrao for many of his life. Notoriously polluted, the canal was constructed to assist drain rainwater away from town into the Chao Phraya. Over its 31-kilometer size, the canal is residence to over 7,000 low-income households.
Samnieng remembers that the world was once primarily paddy fields, however because the city inhabitants sprawled, it changed into a preferred space for rural migrants to realize a foothold in Bangkok.
“I’ve seen a change within the lifestyle, with extra housing alongside the river as individuals transfer in, and with individuals utilizing extra plastic,” says Samnieng.
Samnieng now works with the TerraCycle International Basis, a challenge of the recycling firm TerraCycle that goals to seize plastic waste alongside rivers and canals earlier than it flows into the ocean. The inspiration’s Lat Phrao clean-up challenge began in July 2020.
In 2020, TerraCycle put in two steel cages on the Lat Phrao canal to catch waste earlier than it reaches the Chao Phraya. As soon as caught, it’s simpler for the group to manually scoop the waste from the water. (Picture: Mailee Osten-Tan / The Third Pole)
Mangroves and marine life
Mangroves develop alongside the final stretch of the Chao Phraya, completely tailored to the brackish water the place the river meets the ocean. On the mouth of the Chao Phraya, the muddy mangrove forests of Samut Prakan province are coated in plastic, a testomony to how a lot waste the river is carrying.
The tangled roots and dust of the mangrove forests in Samut Prakan entice giant quantities of plastic waste carried by the river. By this stage, a whole lot of the waste has already been damaged down into microplastics. (Picture: Mailee Osten-Tan / The Third Pole)
What waste doesn’t get caught by the twisted roots of the mangroves is funneled out into the Gulf of Thailand.
Rivers are an necessary contributor to plastic waste on the planet’s oceans, says Suchana Chavanich, a professor with the Division of Marine Science at Chulalongkorn College in Bangkok. “We estimate about one to 2 million tonnes of the plastic waste ending up within the ocean is from rivers,” she says. The scenario is especially unhealthy in Asia, which is residence to the world’s “prime 20 polluting rivers”.
That is having a significant impression on marine life, with animals not solely turning into entangled in particles, but additionally mistaking gadgets like plastic luggage for meals.
In 2018, a pilot whale was discovered lifeless in southern Thailand after it swallowed 80 plastic luggage, leaving it unable to eat.
Suchana explains that animals like sharks and sea turtles are “prime predators that management the marine ecosystem. If their inhabitants declines, and so they die due to plastic waste consumption, it impacts the well being of the ecosystem.”
The large downside with microplastics
By the point the Chao Phraya reaches the ocean, a whole lot of the plastic waste it’s carrying is just too small to see, having been damaged down into microplastics (outlined as items smaller than 5 millimeters).
Analysis has discovered that microplastics hurt the well being of mangrove ecosystems by hindering fuel trade and releasing dangerous chemical compounds. They’re additionally coming into aquatic meals chains, to not point out our personal our bodies. “Scientists have discovered that we are able to [consume] microplastics via the meals that we eat, the water that we drink, and the air that we breathe,” says Suchana.

Aquaculture is frequent on the Chao Phraya, and one other supply of plastic air pollution each massive and small. Uncovered to the weather, the plastic nets and floats used on the farms slowly disintegrate, releasing microplastics into the water. (Picture: Mailee Osten-Tan / The Third Pole)
Microplastics have even been present in human blood. The impression on people remains to be a comparatively new space of analysis that requires time to determine causal hyperlinks. However already, research are exhibiting that the consumption of seafood that comprises microplastics can have implications for our well being.
Roadmaps to stopping plastic air pollution?
In 2019, the Thai Ministry of Pure Assets and Surroundings launched the Roadmap on Plastic Waste Administration (2018-2030). The plan outlines targets for numerous companies to cut back plastic waste, together with a proposed ban on 4 varieties of single-use plastic by 2022: light-weight plastic luggage, polystyrene meals containers, plastic cups and plastic straws. Nonetheless, the Covid-19 pandemic interfered with the achievement of those targets and reportedly triggered an increase in plastic use.

As soon as sorted, the recyclable waste is press packed and despatched to a recycling facility the place it’s changed into plastic pellets that can be utilized to make gadgets akin to chairs and bottles. Recycling plastic reduces its high quality, and so can solely be repeated a couple of occasions with out including virgin plastic. (Picture: Mailee Osten-Tan / The Third Pole)
In 2021, the Division of Marine and Coastal Assets introduced a collaboration with non-profit The Ocean Cleanup to deal with riverine plastic air pollution within the Chao Phraya. The challenge contains deploying a vessel often known as the Interceptor to acquire plastic particles, in addition to monitoring the circulation of plastic waste via bottle-tagging and inserting cameras on bridges alongside the river.
“[Through this research], we are able to acquire an correct measure of how a lot [plastic] waste is passing via the river,” says Suchana. “Hopefully this information will probably be very helpful for additional administration on this space.”
Although the Thai authorities and non-government organisations try to higher handle plastic waste within the rivers and oceans, Suchana stresses that the very best answer is to forestall plastic from stepping into waterways within the first place.
“When plastic waste goes from the river into the ocean… it takes [up to] 500 to 600 years to decompose. So you’ll be able to see that when it will get there, it’s going to keep there nearly perpetually,” Suchana says.
For Sira Leepipattanawit from the Bangkok Yai canal, “It is a downside for humanity, not simply waterside communities. It’s a downside for all lives that begins with us people.”
