California Can Conserve, and Has!
  • Urban
    • Since 1980 per capita water use has decreased by up to 33% in some regions
    • Now at 192 gallons per capita per day
  • Agriculture
    • Has invested approximately $1.5 billion of in water conservation and efficiency upgrades (AWMC 2009)
    • 60% of irrigated acreage is gravity-fed (2001)

How do we accelerate progress?

Sustaining California Agriculture:Agricultural Water Conservation Potential
  • Efficient Irrigation Technology – shifting from flood irrigation to sprinkler and drip systems;
  • Improved Irrigation Scheduling – using local climate and soil information to schedule irrigation; and
  • Regulated Deficit Irrigation – applying RDI to almonds, pistachios, wine grapes, raisins.
benefits of reducing applied water
Benefits of Reducing Applied Water
  • Improves water quality
  • Increases the volume and improves timing of instream flows
  • Reduces need for capital-intensive infrastructure
  • Reduces vulnerability to water-supply constraints
3 make policy relevant recommendations
3) Make Policy-Relevant Recommendations
  • Update water efficiency standards.
  • Provide financial incentives to facilitate the adoption of water conservation and efficiency improvements, target areas with most potential.
  • Improve water use monitoring, particularly for outdoor water consumption.
  • Eliminate pricing policies that subsidize the inefficient use of water.
