Sedudu Island in Botswana (also known as Kasikili Island in Namibia) is a fluvial island in the Chobe River, in Botswana adjacent to the border with Namibia. The island was the subject of a territorial dispute between these countries, resolved by a 1999 ruling of the International Court of Justice (ICJ) that the border runs down the thalweg of the river immediately north (not south) of the island. The island is approximately 5 square kilometres (2 square miles) in area, with no permanent residents. For several months each year, beginning around March, the island is submerged by floods. The Island is one of the top tourist attractions in Chobe.
