3-8: Impact of Global Change on Water Resources and Water Use

Pre-Class Preparation

Objectives

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.

Procedure
