Research Shows Large-Scale Irrigation Reduces Local Precipitation

LINCOLN - A University of Nebraska-Lincoln researcher has shown widespread irrigation has resulted in a net moisture loss in Nebraska, a finding that could have worldwide water conservation implications if substantiated by further research.
Across Nebraska, runoff rates have generally dropped by a little more than a tenth of an inch per decade between 1979 and 2015, said Joe Szilagyi, a research hydrologist with the Conservation and Survey Division in the School of Natural Resources.
