Descriptif
Desertification - defined for the purposes of this book as "land degradation in arid, semi-arid and dry sub-humid areas resulting from various factors including climatic variations and human activities" - is now a direct threat to over 250 million people around the world, and an indirect threat to a further 750 million people.
In the last 25 years, desertification has become increasingly apparent in the dry sub-humid regions of the world, where average annual rainfall ranges from 750 to 1500mm, and where the majority of the human inhabitants of the drylands now live.
