3-10: Impact of Global Change on Water Resources and Water Use
Importance of this Unit to the Course
In Block 2 we saw that observations of both the
recent and distant past reveal wide fluctuations in global patterns of precipitation. And
climate models suggest future climates also will include changes from current conditions. In
this unit we examine how such future climates will impact water resources, an increasingly
critical element in societies with increased population and improved living standards.
- To review how societies use water and to examine the patterns of
water use in various regions.
- To explore opportunities for reduced water use and reducing risk due
to variability in water supplies.
