Somalia’s natural and human geography is shaped by its harsh climate. Lying at the eastern extremity of the Sahel, Somalia has an arid to semi-arid climate. The country is in the midst of a prolonged and complex climate disaster, which shows little sign of abating. It has recently endured its longest drought in four decades, now punctuated with renewed flooding. This Climate Risk Review aims to systematically summarize existing knowledge on Somalia’s climate risks in an accessible and standardized form. It has developed a set of semiquantitative metrics to summarize and compare risks.
