Desertification’s Effects on Lake Chad

Chad – April 29th, 2013

Some dust can be seen over the northern lobe of Lake Chad and blowing about the arid terrain north of the lake. Lake Chad is an example of desertification, the process by which land turns desert-like. During the 1960s, Lake Chad was 38,000 square kilometres of sparkling blue-green water that nourished humans, animals and plant life in the four countries it straddles: Chad, Cameroon, Niger and Nigeria.

However, Lake Chad is now a speck of what it was five decades ago, measuring just 1,300 square kilometres. The Sahara desert is the culprit. It is stealthily moving southward, expanding at the rate of about 48 square kilometres every year, according to some reports. Desertification is a growing problem in Africa and other parts of the world, and will cause more conflict and food insecurity as climate change spurs it on.

Dust Over Niger and Nigeria

Chad – February 1st, 2013

Dust from the Sahara Desert veils the skies over Chad, Niger and Nigeria (counter-clockwise from upper right). The dust is less thick in Chad and by Lake Chad, where the three countries share borders. The dust also clears in northern Niger, where the Aïr Mountains are visible upon opening the full image.

Niger – December 25th, 2012

Dust in Niger blows around the Aïr Mountains, a plateau that forms an island of Sahel climate amidst the Sahara Desert sands and supports a wide variety of life. While the dust here appears to be carried northward, Niger’s neighbor to the south, Nigeria, is experiencing growing desertification as rising temperatures allow the edge of the Sahara Desert to creep closer to the country.

Niger and Chad – December 24th, 2012

Three plumes of dust from the Sahara Desert can be seen blowing west-southwestward in this image of West Africa. Near the center, northeast of Lake Chad, are two light, parallel plumes originating from the Bodélé Depression, in Chad. Near the left edge, south of the Aïr Mountains, in Niger, is the last plume of dust, darker tan in color than the other two and apparently carrying fewer particles. In the lower part of the full image, smoke and fires can be seen across the Central Africa Republic, Cameroon and Nigeria (right to left).

Chad – December 17th, 2012

Dust from the Bodélé Depression (right edge, fully visible in full image), in Chad, blows southwestward, north of Lake Chad, and into the neighboring countries of Niger (above) and Nigeria (below), in the lower left quadrant. North of this cloud of dust are the volcanic Aïr Mountains, in Niger.
