Sudden onset disasters, such as earthquakes, tsunamis, floods and tropical cyclones, are likely to displace nearly 14 million people worldwide each year, warns a United Nations-backed study released Friday – International Day for Disaster Reduction.

“This is an important baseline against which we can measure progress in reducing disaster risk. The findings underline the challenge we have, to reduce the numbers of people affected by disasters,” said Robert Glasser, the UN Secretary-General’s Special Representative for Disaster Risk Reduction.

“Apart from death or severe injury in a disaster event, there is no more crushing blow than the loss of the family home which is often a place of work in many of the countries worst affected,” he added.

The numbers of internally displaced people, refugees and migrants are at an all-time high. Besides conflict, disasters trigger a significant percentage of such movements. Unless disaster risk is managed better, homelessness among people in the world’s most disaster-prone countries is predicted to continue rising.

The study, covering 204 countries and territories, shows that eight of the 10 countries with the highest risk of future displacement and loss of housing are in South and Southeast Asia.

In India, 2.3 million people face such risk, followed by China at 1.3 million; Bangladesh at 1.2 million; Vietnam at 1 million; the Philippines at 720,000; Myanmar at 570,000; Pakistan at 460,000; Indonesia at 380,000; Russia at 250,000; and the United States at 230,000.

INTERVIEW: Few global issues as urgent as tackling climate and disaster risks – Robert Glasser

The study was conducted by the Internal Displacement Monitoring Centre of the Norwegian Refugee Council and the UN Office for Disaster Risk Reduction (UNISDR), using probabilistic risk models for disasters, developed by UNISDR, which have been used to calculate estimates of future economic losses from a range of natural hazards.

This is the first time that these techniques have been applied to forecast potential average numbers of people made homeless over long periods of time. Slow on-set disasters attributed to drought and sea-level rise are not included.

“The Sendai Framework for Disaster Risk Reduction adopted by UN Member States two years ago has a key target for a substantial reduction in the numbers of people affected by disasters by 2030 and these findings should spur efforts to improve land zoning and the quality of buildings especially in seismic zones and on land exposed to storms and floods.” Mr. Glasser said.
