Have students realize that there are much more subtle and effective ways than war to increase water supply. Shift focus from supply to demand, so that students also consider solutions to water stress that reduce demand. Introduce a more holistic approach to water issues, including especially international cooperation and water treaties. Provide an overview of some of the historical, geopolitical, and economic interactions among the Nile's riparian neighbors that lead to conflict over water. Use game theory to model water competition.
