1. Irrigation
Intro Video (Action Movie) (very exciting)

2. Types of Irrigation Flood irrigation: 60% efficient
Capture and reuse could catch the runoff in a pond and pump it back our to irrigate again.

3. Spray irrigation: ~65 % efficient (Getting better!)
lose water by evaporation/wind
LEPA: ~95% efficient
low energy precision application,
High pressure sprinkler

4. Center-pivot: ~80-95% efficient Drip irrigation: ~90-95% efficient
low pressure spray that moves in a circle
Drip irrigation: ~90-95% efficient
pipes with holes, water goes to roots, less salinization
Drawback: Expensive to install!!!

5. Other good ideas: Soil moisture detectors
Mulching (Helps with water retention)
Growing deep root plants
Import water intensive crops/meat
Line irrigation canals and ditches
Plastic covers over plants. Why?
Xeriscaping: Use native vegetation or stones to decorate yard
reduces need for extra irrigation
Treat waste water for irrigation: gray water
