One of the first studies to examine how climate change might alter the land surface of Africa has been published by scientists from Oxford University.

Their research details how the immense dunefields of the Kalahari could be stirred up by global warming.

The investigation, reported in the journal Nature, warns that large areas of currently productive land could become engulfed by shifting sands.

"The social consequences of these changes could be drastic," they say.
