Farmers, ranchers and foresters in some regions of the U.S. contend with an overabundance of water while other regions are frequently challenged by drought and water scarcity. The 100th meridian is often touted as the dividing line between the wet eastern United States and the dry, water-limited west. Projected changes in average annual precipitation show increases in much of the northern U.S. and decreases in the southern U.S., exacerbating the water-related challenges already faced in these areas. For example, an increase in spring precipitation may reduce the number of workable field days, reduce crop yields and disrupt planting operations in wetter regions. Extreme precipitation has generally increased and is projected to continue to increase across the U.S. with a warming atmosphere. Flooding related to more extreme precipitation could impact agricultural production and surface water quality as nutrient concentrations and sediment loads are washed from fields into nearby waterways. More extreme precipitation could also increase climate risk from aging water infrastructure.
