Large-scale involuntary migration is the most likely and serious problem facing the world in the next year and a half, according to a flagship annual report from the World Economic Forum (WEF.)
"The key findings, I'd say this, year, are that it is a riskier environment and sources of instability are broadening to include geopolitical frictions, societal risks like the refugee crisis, weather, cyber — they are all out there," John Drzik, the president of global risks and specialties at Marsh, which collaborated on the report, told CNBC.
Other top risks included interstate conflict, extreme weather, failure to mitigate or adapt to climate change, weapons of mass destruction and a severe energy price shock, the foundation reported on Thursday. Its annual report was based on a survey of more than 13,000 executives in 140 countries, across business, academia, civil society and the public sector.
