Desertification, the loss of the soil's biological productivity, occurs
naturally to a limited extent. The pace at which the process has
spread recently, however, is largely man's own doing. This fact was
highlighted by the great Sahel drought of 1968-73. The worst effects
5 of this drought were caused by nomadic peoples who had earlier been
forced by national governments to adopt agricultural and grazing
practices that were not in accord with their traditions. In common
with those of other nomads around the world, such traditions involved
never staying in one place so long as to exhaust the earth that provided
10 them with sustenance. When these people were not allowed to follow
this tradition, the process of desertification moved ahead quickly.
