How to achieve the required food
production to meet the growing demand
Increasing Irrigation System Efficiency
Tony Oakes & Tugba Erol
Rubicon Systems
Overview
• Irrigation is key to producing more food
• Irrigation consumes approximately 70% of
the world’s water
• Gravity channel systems are the dominant
delivery mechanism – unlikely to change
• Operating technology has changed little
since the early civilizations - inefficient
• Modern infrastructure and control
engineering can increase distribution
efficiencies from ~50-70% to ~70-90%
• This realizes massive water savings
