The Mississippi Delta, the MAV and the World: The Groundwater Crisis—is there any hope?

Author(s): Johnson, D.

Mankind has been overdrawing its aquifers for more than 20 years in order to feed the ever expanding population. Is this a sustainable policy? In parts of the high plains aquifer of the U.S., many landowners who have been irrigating crops for over 50 years no longer can draw water from their wells. Closer to home in Arkansas, producers are now drawing water from the Sparta aquifer, which is generally reserved for drinking water, to supplement their withdrawals from the MAA for crop irrigation. USGS groundwater modeling studies show that the water level in the MAA will continue to decline for the foreseeable future. This presentation will discuss the actions the state or producers can take to reverse the decline in the MAA.
