Flooding has deluged parts of the US Midwest, where rising river water levels have inundated many communities. The governments of Nebraska, Iowa, Wisconsin, and Mississippi have all declared states of emergency due to record flooding, and, with additional rains forecast for later this week, the water does not look likely to subside anytime soon. These four states are extremely important to the overall agricultural economy in the United States, accounting for 25 percent of the national production value of major crops, and 23 percent of the production value of livestock products in 2017.
