Desertification Unit Outline
It is estimated that nearly one-quarter of the world's total land area
is dryland, excluding hyper-arid areas (deserts) and at risk from desertification.
At the end of this unit you will understand the factors affecting the
balance of naturally dry ecosystems and the difficulty of these regions
to rebound from the increasing change in climate conditions and human pressures.
You will also be able to make clear connections with climate and soil studies.

What causes desertfication? How is it related to drought?
