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.
