The number of people impacted by seasonal flooding in East Africa has increased six-fold in the last five years, according to data given to BBC by the United Nations. BBC Africa reports that nearly 6 million people have already been affected this year with 1.5 million of them displaced from their homes. The United Nation’s Office for the Coordination of -Humanitarian Affairs, which plays a central role in the emergency response when floods hit the region revealed that the data it has gathered paints a worrying picture. Scientists increasingly believe the warming of the Indian Ocean is driving increased rainfall. A recent study from the University of Texas suggests the volume of the short rainy season could double by the end of this century.
