Over 42 million people across the world were forced to flee due to disasters triggered by sudden‐onset natural hazards in 2010, according to a new study by the Norwegian Refugee Council (NRC)’s Geneva‐based Internal Displacement Monitoring Centre (IDMC). In 2009, 17 million people were displaced by such disasters, and 36 million in 2008. ...The number of natural disasters reported has doubled from around 200 to over 400 a year over the past two decades. In 2010, over 90 per cent of disaster displacement within countries was caused by climate‐related hazards, primarily floods and storms.
Elsewhere, the audio and video for a recent Brookings-LSE Project on Internal Displacement event on "Responding to Natural Disasters" is now available. You can also read a summary of the event in this blog post from Refugees International.
