Climate change is fuelling conflicts around the world and helping to drive the number of people forced out of their homes to new highs, the head of the UN's refugee agency said yesterday. After a few years of improvement, thanks mainly to large-scale resettlement in Afghanistan, the numbers of civilians uprooted by conflict is again rising. During 2007 the total jumped to 37.4 million, an increase of more than 3 million, according to statistics published today.

The figures, described as "unprecedented" by the UN, do not include people escaping natural disasters or poverty - only those fleeing conflict and persecution. But Antonio Guterres, the UN high commissioner for refugees, said that climate change could also uproot people by provoking conflicts over increasingly scarce resources, such as water. - The Guardian
