Bangkok Officials Look at Ways To Defend against Flooding

Bangkok, the capital city of ASEAN member Thailand, is considering various methods and construction initiatives to defend itself from continuously rising sea levels which threaten to flood, and one day possibly sink, the city of more than 8 million people.  

City officials tell the Financial Times that flooding is the top concern for Bangkok, alongside traffic.

Bangkok city planners, officials, and university researchers are all reviewing and looking to pilot various projects to defend the city from the worst possible consequences of climate change, which could include the city ending up under water in a few decades.  

The plans include building a giant wall with floodgates around the city, building an elevated motorway along the coast to serve as an embankment, or planting mangroves to prevent erosion and keep sediment under the city. Bangkok is also widening the network of canals and tunnels to help control water from floods.

But the city may need more measures, urgently, to defend itself from rising sea levels.

“The flood prevention system for Bangkok is good as it is, but it’s not promising for the future climate change scenario,” Tara Buakamsri, Thailand Country Director for Greenpeace Southeast Asia, told FT.
According to new research from Climate Central, an independent organization of leading scientists and journalists reporting about climate change, rising sea levels could within three decades push chronic floods higher than land that is currently home to 300 million people.

With rising sea levels, frequent flooding is set to threaten more land that will be permanently lost to the ocean. By 2100, land currently home to 200 million people could fall permanently below the high tide line, according to the research.

China, Bangladesh, India, Vietnam, Indonesia, and Thailand are currently home to the greatest number of people living on land that could be permanently flooded by 2100, Climate Central said in the research published at the end of October.
