For the first time in the survey’s 10-year outlook, the top five global risks in terms of likelihood are all environmental. They are: extreme weather events, failure of climate change mitigation and adaptation, major natural disasters, major biodiversity loss and ecosystem collapse, and human-made environmental damage and disasters.

Until recently, impressive economic growth, stable leadership and its attractiveness as a foreign investment hub put Ethiopia in a positive spotlight. However, the country still ranks low in human development and is highly dependent on rainfed agriculture, making it particularly vulnerable to climate change impacts.
