New global data sets enable up-to-date estimates of the number of persons displaced by disasters (IDMC, 2014

). The figures are not encouraging, particularly for weather-related disasters, as they show a clear upward trend over time (Figure 5.7), with 143.9 million people displaced by disasters between 2008 and 2012 alone.
Displacement is particularly associated with weather-related disasters (Figure 5.8). International estimates of displacement trends and patterns are hampered by limited data availability. Due to the multidimensional and complex dynamics of migration and displacement, quantitative projections for future trends have low confidence levels, even though there is agreement that climate change will drive future displacement and patterns of movement (IPCC, 2014

Where data is available, it highlights that disaster impacts go far beyond the immediate loss of assets. Between 2008 and 2014, for example, it is
estimated that 165 million people were displaced by disasters (IDMC, 2014

).
While mobility, migration and displacement are sometimes consequences of disasters, they can
