updated, hosted by the UNICEF Innocenti Research Centre has updated its digital library and added the 2007 report by Save the Children UK, Legacy of Disasters: The Impact of Climate Change on Children. From the report:

Overall, natural disasters are likely to lead to unprecedented numbers of ‘environmental refugees’ or ‘environmentally displaced people’. Regions that rely most heavily on agriculture will be most affected; environmental migration is already most acute in sub-Saharan Africa, but millions of people in Asia and India are also on the move.
“The UN estimates that by 2010 there will be 50 million such people worldwide. Given the demographics of the countries most likely to be affected and the traditional composition of displaced populations, most environmentally displaced people will be women and children”.
