Since 2008, an average of 26.4 million people have been displaced from their homes each year by disasters brought on by natural hazards- equivalent to one person displaced every second. The time is opportune to ensure the causes and consequences of this urgent issue are better addressed. Policy makers are pushing for concerted progress across humanitarian and sustainable development goals, including disaster risk reduction and action on climate change. This annual report, the sixth of its kind, aims to equip governments, local authorities, civil society organisations and international and regional institutions with evidence relevant to these key post-2015 agenda. The report draws on information from a wide range of sources, including governments, UN and international organisations, NGOs and media, to provide up-to-date statistics on the incidence of displacement caused by disasters associated with geophysical and weather-related hazards such as earthquakes, volcanic eruptions, floods and storms.
