Demand Management Options

  • We need to reduce consumptive use:
  • Allocation
  • Allocation + Water Market
  • Land Resting/Retirement Easements
  • Fee structures
  • We need to show good faith to GSA partners
  • We need to avoid state intervention
  • We need to understand trends in terms of the magnitude of

reduction

  • We acquired satellite-based ET analysis for 2010-2019 to look at

recent changes in agricultural water use as it informs an allocation approach

  • Remote sensing is the only way to estimate actual ET over large areas and long time

histories

  • Field scale satellite archives combined with availability of climate data and cloud

computing is creating transformative opportunities

  • Rapid processing and visualization tools for simple consumptive use decision support
  • Will allow for all to perform field scale consumptive use analyis
  • Free and open access to objective data where everyone is treated equally will reduce the likelihood for

disputes over data or lack of data

  • Outreach through hands-on training is key for adoption
  • Contact Justin.Huntington@dri.edu if interested in participating or for more details
