Flood-prone populations up nearly 25% worldwide since 2000 – Study

0 205

Flooding is by far the most common of extreme weather events made more frequent and potent by rainfall patterns supercharged by climate change.

Deadly inundations, such as recently in India, China, Germany and Belgium, inflict billions worth of damage, often disproportionally affecting poorer sectors of society.

Most flood maps rely on modelling based on ground-level observations such as rainfall and elevation, but they can often entirely miss ewgions that are historically not flood-prone.

To fill in those gaps, a team of US-based researchers examined satellite data from twice-daily imaging of more than 900 individual flood events in 169 countries since 2000.

They used the data to create the Global Flood Database, which provides open source information on the death cpunt, displacement and rainfall levels linked to each of the 913 floods.

Writing in the journal Nature, the researchers found that up to 86 million people, driven by economic necessity, moved into known flood regions between 2000-2015 — a 24-percent increase.

A total of 2.23 million square kilometres (860,000 square miles) — more than the entire area of Greenland — were flooded between 2000 and 2018, affecting up to 290 million people. And it’s only going to get worse. – INDIA TODAY
