Desertification and Vanishing Lake Chad

Chad – June 19th, 2013

As you approach the Lake Chad basin the air is dusty, the wind is fierce and unrelenting, the plants are wilting and the earth is turning into sand dunes. The sparse vegetation is occasionally broken by withered trees and shrubs. The lives of herders, fisherfolk and farmers are teetering on the edge as the lake dries up before their eyes.

Vegetation and water, the traditional staples of livelihood for the Lake Chad community dwellers, are vanishing. Vultures feast on dead cows as drought and desertification take their toll. The UN Food and Agriculture Organization (FAO) has called the situation an “ecological catastrophe,” predicting that the lake could disappear this century.

The Lake Chad basin is one of the most important agricultural heritage sites in the world, providing a lifeline to nearly 30 million people in four countries — Nigeria, Cameroon, Chad and Niger. Lake Chad is located in the far west of Chad and the northeast of Nigeria. Parts of the lake also extend to Niger and Cameroon. It is fed mainly by the Chari River through the Lagone tributary, which used to provide 90 per cent of its water. It was once Africa’s largest water reservoir in the Sahel region, covering an area of about 26,000 square kilometres; however, by 2001 the lake covered less than one-fifth of that area (click here for more information).

Niger and Mali – June 1st, 2013

A close inspection of this image reveals yellow dust blowing about in the air over Niger (right) and Mali (left). Mostly unaffected by the dust due to their high altitude are the Aïr Mountains. Lying in the midst of the Sahara Desert, with an average altitude between 500 and 900 m (1,600 and 3,000 ft), the mountains form an island of Sahel climate which supports a wide variety of life.

The dust storm that has been affecting Chad, Nigeria and Niger over the last few days continues to affect the region, although it has waned slightly. Unlike yesterday (click here for previous image), Lake Chad is now mostly visible.

Chad – May 9th, 2013

A dust storm continues to blow across the border between Chad, Nigeria and Niger, visible here crossing the center of the image. The dust blocks most of Lake Chad (lower right quadrant), shared by the aforementioned three countries and Cameroon, from view.

Chad – May 8th, 2013

Strong winds are kicking up dust from the Sahara Desert in this image, creating a hazy veil over Chad and Niger. The veil partially obscures Lake Chad (below, center) and the Tibesti Mountains (above, right). While dust storms are common the in the region, increased frequency may point to climate change.
