Since 1970,85 per cent of disasters in the region have been minor but recurrent. They have cumulatively affected 2.24 billion people and caused more than $400 billion of damage by triggering ongoing erosionof development assets, such as local infrastructure, dwellings, schools, health facilities and roads. While hazards and exposure dominate the risk equation for intensive risk, extensive risk is more closely associated with such factors as inequality and poverty. As indicated by figure II, the range of major floods, droughts, cyclones and typhoons in the region since 2009 have had the worst sectoral impact on the housing and agriculture sectors, resulting in 23 and 21 per cent of the total loss in these cases respectively. Comparatively, over the same period, major disasters in the Asia-Pacific region have resulted in losses of 14 per cent in the transport sector and 7 per cent in the tourism sector.
