Extreme points of the African Union

Main article: Geography of Africa

The African Union covers almost the entirety of continental Africa and several off-shore islands. Consequently, it is wildly diverse, including the world's largest hot desert (the Sahara), huge jungles and savannas, and the world's longest river (the Nile).


The AU presently has an area of 29,922,059 km² (18,592,705 mi²), with 24,165 km² (15,015 mi²) of coastline. The vast majority of this area is on continental Africa, while the only significant territory off the mainland is the island of Madagascar (the world's fourth largest), accounting for slightly less than 2% of the total.

Countries bordering the African Union

The AU has two land borders: Algeria and Western Sahara[2] border Morocco on its east for 1,559 km (68 mi) and south for 443 km (275 mi) respectively, and Egypt's Sinai Peninsula borders the Gaza Strip for 11 km (6.8 mi) and Israel for 400 km (248 mi) on its western frontier. Since it is Asian, the Sinai is the only territorial region of the AU on another geopolitical continent.
