UNDERSTANDING DROUGHT AND DESERTIFICATION
The areas of the earth with low amounts of annual rainfall maintain a fragile balance of life, a balance that human exploitation often tilts toward the side of permanent desertification.
Learning Objectives:
1) Terminology used to discuss drought and the process of desertification will be introduced.
2) Lands that are in danger of becoming deserts will be discussed and the particular conditions that threaten these areas will be identified.
3) It will be shown that the impact of people on the land is often more detrimental to its productivity than are changes in climate.
