Satellite pictures of northern Africa show that areas
lost to the Sahara desert during decades of drought are turning green
again. Analysis of images show deserts retreating in a broad band stretching
from Mauritania to Eritrea, according to research in British magazine
New Scientist. The driving force behind the retreat of the deserts is
believed to be increased rainfall. This helping to transform thousands
of hectares into productive fields – where nothing grew just a decade
ago.
