Dust Storm Near Lake Faguibine and Inner Niger Delta, Mali

Mali – May 19th, 2013

A dust storm in Mali blows a thick,  yellow cloud of sand towards Lake Faguibine (identifiable here as an elongated dark area near the top edge) and the Inner Niger Delta (center left).

Lake Faguibine is a lake in Mali on the southern edge of the Sahara Desert situated 80 km west of Timbuktu and 75 km north of the Niger River to which it is connected by a system of smaller lakes and channels. In years when the height of the annual flood of the river is sufficient, water flows from the river into the lake. Since the Sahel drought of the 1970s and 1980s the lake has been mostly dry. Water has only rarely reached the lake and even when it has done so, the lake has been only partially filled with water. This has caused a partial collapse of the local ecosystem.

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. The Niger inland Delta lies in the Sahelian zone, and has an ecosystem that is largely dependent on the amount of flooding it receives. Due to its proximity to the widening Sahel, there have been concerns that the delta may be getting less rain every year. Here, the delta appears quite dry, blending in with the surrounding terrain rather than showing a great deal of green vegetation.

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.

Mali - January 10th, 2012

The Niger River is the principal river of western Africa, extending about 4,180 km (2,600 mi), and the third longest river in all of Africa. Its drainage basin is 2,117,700 km2 (817,600 sq mi) in area. Its source is in the Guinea Highlands in southeastern Guinea. It runs in a crescent through Mali, Niger, on the border with Benin and then through Nigeria, discharging through a massive delta into the Atlantic Ocean.

This image, however, focuses the Inner Niger Delta, also known as the Macina or Niger Inland Delta, 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. As this image was captured during dry season, which lasts from October to June, not much water or plantlife can be seen.

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.
