Counting disaster: Who's dying where?


From the 2004 Asian tsunami to Hurricane Katrina in the US, the past decade has seen more recorded natural disasters than any since records began, according to researchers.

They say improvements in recording systems do not fully account for the increase. Some 2.7bn people - the equivalent of more than a third of the world's current population - were affected by natural disasters between 2000 and 2010, although the number of people dying has dropped over recent decades.

Where are people most affected? What types of extreme natural event are wreaking most havoc? What can data tell us about human vulnerability to the forces of nature?

The information used in the video is mainly from the Centre for Research on the Epidemiology of Disasters, run by a Belgian university in collaboration with the World Health Organization. CRED defines a natural disaster as an event when 10 or more people are killed, 100 or more are affected, a state of emergency is declared, or international assistance is requested.

This week, the BBC's One Planet programme chaired a debate about natural disasters with local and international experts, next to a swollen river in Bangkok. Click to listen.
