VI. Midwest USA and Canadian Prairies

Agricultural heartland – mostly rainfed with some areas relying heavily on irrigation:

  • Annual streamflow decreasing/increasing; possible large declines in summer streamflow
  • Increasing likelihood of severe droughts
  • Possible increasing aridity in semi-arid zones
  • Increases or decreases in irrigation demand and water availablity – uncertain impacts on farm-sector income, groundwater levels, streamflows, and water quality
