A warmer Indiana will challenge crop and livestock production

With ample rainfall and favorable temperatures, Indiana has become a top producer of U.S. corn, soybeans, hogs, chickens, and specialty crops such as tomatoes and watermelon. However, continued success is uncertain as CO2 concentrations rise in the atmosphere and global climate patterns shift. Researchers investigated the direct and indirect consequences of climate change on Indiana’s agricultural sector. Due to increased heat and water stress, they report the likelihood of reduced yield potential in row crops, decreased livestock productivity, shifting suitability for certain varieties of perennial crops, and soil and water quality reductions. While there is potential for significant impacts, the researchers note there are many opportunities available to cope with changes and keep Indiana agriculture productive.
