Question 1

Explain two ways in which human activity increases the danger of drought and desertification.

Accepted Answer

​ 
 A successful answer will include two of the following: 
 - damming of rivers or increased use of water upstream reduces soil moisture downstream. 
 - overgrazing by livestock or wildlife, concentrated in an area by fencing or artificial water sources, breaks up soil, compacts deeper soil, and reduces water infiltration. 
 - cultivation decreases soil moisture by exposing more soil to heat and air. 
 - topsoil disturbed by cultivation can dry and blow away, exposing deeper soils to evaporative processes.
