Global Water Resources and Management

The video tutorial introduces the WaterSim model, developed by the Decision Center for a Desert City, to explore water sustainability. It defines water sustainability as managing water to meet current needs without compromising future generations. The tutorial discusses the complexities and uncertainties in water planning, the distribution of global water resources, and the impact of climate change. It highlights different water usage patterns and explains how the WaterSim model can simulate policy outcomes to manage water supply until 2050.

What is the primary purpose of the WaterSim model?

• To predict weather patterns

• To desalinate ocean water

• To manage water resources sustainably

• To develop new water sources
