Mali - December 22nd, 2011

This image of Mali shows the Sahara Desert just north of the Niger River and the Inner Niger Delta (bottom center). The wetlands of the delta do not appear very large or green because the region is still experiencing the dry season.

In the upper left quadrant, an area of red desert can be observed. This is part of the Sahara in Tombouctou, the largest and northern-most region of Mali, famous for its capital, the ancient city Timbuktu. The city itself is located at the southern edge of the Sahara, near the Niger River.

Mali - December 22nd, 2011

The Inner Niger Delta, also known as the Macina, is a large area of lakes and floodplains in the semi-arid Sahel area of central Mali, just south of the Sahara desert (visible in the upper part of the image). 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.

Most of the year the Macina 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. This image was taken during dry season, when there was no flooding and little vegetation.

 

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.

Dust from Sahara Desert Extends Southwards Over Nigeria

Nigeria - December 10th, 2011

Dust from the Sahara Desert can be seen blowing southward over Nigeria, reaching towards the coast. The dust probably originated in the neighboring country of Niger (click here for an image of the dust storm in Niger).

Visible south of the clouds of dust is the Niger River, the principal river of western Africa. After extending about 4,180 km (2,600 mi) through various countries, it runs across Nigeria and discharges through a massive delta, known as the Niger Delta, into the Gulf of Guinea in the Atlantic Ocean.

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.
