West Africa – December 31st, 2012

Fires can be seen in West Africa, south of the Niger Inland Delta (top center). Most of the fires are concentrated in the lower right quadrant, in Ghana and Côte d’Ivoire, and are releasing plumes of smoke that blow southwestward. In the full image, Lake Volta, in Ghana, is partially visible through the smoke, and fires can also be seen further west, in Guinea.

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 - 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 8th, 2011

The green area at the bottom center 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 (visible as a tan, sandy expanse occupying 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. The Niger is the longest river in West Africa.

Mali - December 26th, 2010

The Niger River runs across the upper part of this image. The large green area to which it is connected is the Niger Inland Delta (also known as the Inner Niger and Macina Inland Delta), a green area of wetlands in central Mali.

The delta is situated on the middle course of the Niger River, the longest in West Africa. It fills during the wet season, usually between July and September, turning from a swamp into a lake. In this December image, the delta is drying out and turning into a network of lakes and channels.
