Bangkok’s water authority says faucet water is changing into saline as seawater pushes up the depleted Chao Phraya river, a rising danger confronted by lots of Asia’s coastal cities
BANGKOK, Jan 10 (Thomson Reuters Basis) – Thai authorities are trucking ingesting water to elements of Bangkok and urging residents to bathe much less as a worsening drought and rising sea ranges have elevated salinity, a rising danger confronted by many Asian cities, local weather researchers stated.
Bangkok’s water authority stated the capital’s faucet water was changing into saline as seawater pushed up the depleted Chao Phraya river, a supply of a lot of central Thailand’s water.
Prime Minister Prime Minister Prayuth Chan-ocha this week requested the general public to avoid wasting water by taking shorter showers.
Making issues worse, Thailand’s dry season started in November and often lasts by means of April, however this 12 months authorities stated it might final till June and drought has been declared in 14 provinces.
The drought situations have worsened saltwater intrusion, which may have main impacts on farming and on well being as ingesting water is contaminated, stated Suppakorn Chinvanno, a local weather skilled at Chulalongkorn College in Bangkok.
“It’s changing into a extra critical problem, with the intrusion coming farther inland this 12 months and earlier within the season,” he instructed the Thomson Reuters Basis.
“It is going to have a critical affect on agriculture within the area, as rice is a really water-intensive crop,” he stated.
A lot of Asia’s largest cities, together with Mumbai, Shanghai, Bangkok, Ho Chi Minh Metropolis and Jakarta, are coastal and low-lying, making them weak to rising sea ranges and excessive local weather occasions similar to extra frequent and deadlier cyclones.
Indonesia plans to maneuver its capital to the island of Borneo, as Jakarta – on the north coast of Java island – is slowly sinking and suffers common flooding.
Cities situated in deltas must more and more cope with saltwater intrusion, stated Diane Archer, a analysis fellow on the Stockholm Setting Institute in Bangkok.
“The fact of local weather change and sea degree rise means that is more and more going to grow to be a difficulty for delta cities as sea water intrudes into rivers and aquifers, particularly throughout drought and the place groundwater is already depleted,” she stated.
“Bangkok is controlling groundwater extraction however is affected by subsidence, making it extra weak to sea- degree rise. As sea ranges proceed to rise, it’s probably that salinity goes to grow to be a rising risk,” she stated.
Elsewhere within the Mekong Delta, saltwater intrusion is already an issue, with some cities in Vietnam monitoring salinity ranges to alert farmers on whether or not the water is secure for irrigation, Archer stated.
“Farmers could must adapt their crops to these extra suited to brackish water,” she stated.
