In the U.S., 52% of irrigated land is used for corn, soybean and winter wheat production. Corn and soybean are two of the country’s most important crops, with 17% of corn production and 12% of soybean production coming from irrigated areas. However, the water used for this irrigation is often unsustainably pumped groundwater. According to a recent Dartmouth-led study published in “Earth’s Future,” using groundwater sustainably for agriculture in the U.S. could dramatically reduce the production of corn, soybean and winter wheat.
