Even as lawmakers fret this summer’s severe drought might cause another Dust Bowl, environmental groups are sounding alarms that Congress is slated to cut a program designed to prevent such a catastrophe from occurring in dry years.

Both the House and the Senate aim to cut funding for the Conservation Reserve Program (CRP), which pays farmers to take crop land out of production and instead use that acreage to plant trees and grass.

Both the House and Senate versions of the five-year farm bill would cut the CRP funding to limit land taken out of production to 25 million, from its current 32-million acre cap.

The program helps lock in soil and the nutrients used to grow crops, thereby preventing the kind of erosion that plagued the Dust Bowl era of the 1930s.
