Devastating storms and flooding forced people from their homes three times more than violent conflicts did in 2020, when displacements around the world reached its highest figure in a decade.
In a year marked with persistent violence in places such as Ethiopia, Syria and the Democratic Republic of the Congo, conflict triggered 9.8 million displacements of people.
But the number of times people were uprooted by disasters far surpassed that figure, at 30.7 million.
Together these factors brought the total number of new displacements in 2020 to 40.5m, a ten-year high, according to new analysis from the Norwegian Refugee Council’s Internal Displacement Monitoring Centre (IDMC).
The secretary general of the Norwegian Refugee Council, Jan Egeland, called it “shocking” that “someone was forced to flee their home inside their own country every single second last year”.
Weather related events such as storms and floods were responsible for 98% of all disaster displacement, with geophysical events like earthquakes and volcanoes behind the remaining 2%.
Intense cyclone seasons in the Americas, South Asia and East Asia and the Pacific, and extended rainy seasons across the Middle East and sub-Saharan Africa, drove millions of people from their homes.
Cyclone Amphan alone triggered around five million displacements across Bangladesh, Bhutan, India and Myanmar, and the Atlantic hurricane season was the most active on record.
Climate change has created the conditions to make extreme weather events more likely and more numerous, and is expected to increase future displacement.
The report warned against the idea that disasters were something that could be prepared for but not prevented.
And it sought to dispel the “misconception” that disasters were natural, saying human factors have a major role in how they play out.
It said policy tended to overlook that the fact that “exposure and vulnerability of people and assets plays a vital role” in whether a hazard becomes a disaster.
The figures refer to the total number of times people were forced to flee around the world, rather than the overall number of people.
The total number of people living in internal displacement reached a record 55 million at the end of last year.
The IDMC director, Alexandra Bilak said the displacement crises arose from “many interconnected factors, including climate and environmental change, protracted conflicts and political instability”.
“In a world made more fragile by the COVID-19 pandemic, sustained political will and investment in locally-owned solutions will be more important than ever,” she said in a statement.
