Climate change is already increasing the frequency and intensity of
natural hazards, and the numbers of natural disasters reported and
people affected are rising. Although it is clear that natural
disasters are one of the principal causes of forced displacement, data
on disaster-related displacement has not been consistently collected
and analysed. The lack of reliable baseline data on disaster-related
forced displacement has prevented adequate evaluation of the scale of
the phenomenon and the patterns of displacement. It also makes it
dif�cult to extrapolate potential human mobility based on existing
climate change models or scenarios, or to develop realistic assessments
to be taken into account in climate change adaptation policy formation. Climate change is already increasing the frequency and intensity of
