New research published this week from Jerome Dumortier, associate professor in the O'Neill School of Public and Environmental Affairs at IUPUI, and his co-authors, uses economic simulation models to predict the short-term and long-term effects of the war on climate change, crop prices and food shortages.

The study found that the war's impact on crop production and exports in Ukraine and Russia will continue to increase the world's food prices and food insecurity, but not as much as initially feared -- largely because other countries have stepped up their production. Researchers estimate we may see corn and wheat prices increasing by up to 4.6% and 7.2%, respectively. They also considered the prices of crops like barley, rice, soybeans, sunflower and wheat, which are predicted to increase.
