Rising Sea Levels Due to Climate Change Will Impact 15 Million People Across 7 Asian Cities By 2030

A new report by non-governmental environmental organization Greenpeace East Asia analyzes the estimated economic impact of extreme rising sea levels in seven Asian cities in 2030. These cities are Hong Kong, Bangkok, Tokyo, Jakarta, Seoul, Tapei, and Manila.

This is a first of a kind analysis which uses high spatial resolution data to point out cities that are at high risks due to flooding. The report selected seven Asian cities as they are economic hubs and are situated on or close to the coastlines.

The findings reveal that in 2030, 15 million people across these seven cities will be residing in areas which are at risk of flooding due to rising sea levels and intensifying tropical storms. In addition, its gross domestic product (GDP) could possibly be severed affected due to this scenario.

In Hong Kong, tropical cyclones are quite common causing storm surges which have seen the sea level exceed the tide level by over 3 metres. This means around 2% of the city’s land area is below the level to which seawater could rise if a 10-year flood occurs in 2030. This could impact 90,000 people with a loss of US$2.24 billion.

Bangkok
In Bangkok, over 96% of its land area is at risk of flooding. This land area includes residential and commercial spaces in the city’s center. Due to soft soils, heavy urbanization and land sinking, the sea-level rise and coastal flooding could affect 10.45 million people and a total of US$512.28 billion.

This impacted GDP (PPP) accounts for 96% of the city’s total GDP (PPP).
