Mali - November 8th, 2011

The Inner Niger Delta consists of the middle course of the Niger River, the longest river in West Africa. Located in the semi-arid Sahel area of central Mali, just south of the Sahara desert, the delta is a large area of lakes and floodplains. Here, it appears as a green area against the surrounding tan, in the upper right quadrant.

Most of the year the area has a hot and dry climate, with hot winds from the nearby Sahara raising the temperature up to 40° C. During the wet season, which lasts from July to September but lasts longer the further south one goes, the swamp floods into a lake and naturally irrigates the land. When the dry season comes, the Macina turns into a network of lakes and channels. Due to its proximity to the widening Sahel, there have been concerns that the Macina may be getting less rain every year.
