Desertification is the degradation of land in arid, semi arid
and dry sub-humid areas into desert, resulting from various factors including
climatic variations and human activities. Modern desertification often arises
from the demands of increased populations that settle on the land in order to grow crops
and graze animals.(http://wikipedia.org/wiki/Desertification)
