According to USDA data, one of the most
popular places in the country for cover crops
is the Texas panhandle where they can protect
the land from wind erosion as well as sequester
carbon. But some farmers irrigate the cover
crops with water for the Ogallala Aquifer, which
is critical to agriculture for a significant portion
of the western Plains.
Farmers in much of the region have been
using water from the Ogallala faster than it is
replenished. While water levels in the aquifer
have risen in some areas, especially Nebraska,
they are “mostly in decline, namely from Kansas
southward,” according to the National Oceanic
and Atmospheric Administration.
The Fourth National Climate Assessment
warned, “Current extraction for irrigation far
exceeds recharge in this aquifer, and climate
change places additional pressure on this critical
water resource,” the report said. Ogallala .Aquifer .depletion .(photo: .NOAA)
