Inner Niger Delta South of Sahara Desert, Mali

14.6N 5W

November 5th, 2012 Category: Deserts, Rivers

Mali – November 4th, 2012

The bright green area spreading across the otherwise arid, yellow and tan landscape, is the Inner Niger Delta, also known as the Macina. It is a large area of lakes and floodplains in the semi-arid Sahel area of central Mali, just south of the Sahara desert. The delta consists of the middle course of the Niger River, between the bifurcated Niger and its tributary, the Bani, which from here run north towards the desert. Due to its proximity to the widening Sahel, there have been concerns that the Macina may be getting less rain every year.

Vegetation Index of Liberia and Côte d’Ivoire

Ivory Coast - December 11th, 2011

This FAPAR image shows the vegetation index of Côte d’Ivoire (the Ivory Coast, right) and Liberia (left). Visible near the right edge is Lake Kossou, the largest lake in Côte d’Ivoire. It lies in the center of the country on the Bandama River.

The vegetation index is generally good (green), although it becomes progressively lower (yellow) as one moves northwards into the Sahel region. Some patches of high activity (rusty red) can be seen through the clouds near the coast.

Dust Over Burkina Faso Near Inner Niger Delta

Mauritania, Mali, Burkina Faso - December 11th, 2011

This image shows parts of Mauritania, Mali and Burkina Faso, from the Sahara Desert (above) to the Sahel region. Visible in the lower right quadrant is a cloud of dust, blown about by strong winds in the region.

Visible near the dust cloud is the Inner Niger Delta, a large area of lakes and floodplains that consists of the middle course of the Niger River. 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. The wetlands don’t show much evidence of green vegetation in this image, as the wet season ended in September.

Inner Niger Delta in Sahel Area of Central Mali

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.

Mali - October 28th, 2011

The orange and golden sands of the Sahara Desert (above) gradually give way to the less arid Sahel (below) in western Africa. Visible at the right edge in the semi-arid Sahel area of central Mali, just south of the Sahara desert, is the Inner Niger Delta.

The delta, also known as the Macina, is a large area of lakes and floodplains that consists of the middle course of the Niger River. 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.
