—Analyzing the impacts of climate change on regional maize production in the North Central and the South regions of the United States and proposing risk mitigation strategies have significant implications in the context of national and global food security. Unlike most estimation, we use an interdisciplinary approach and combine climatic variables along with economic inputs and technological improvement in the adapted Cobb-Douglas production function model. The production function is simulated through 2030 under a variety of climate change scenarios, and the results indicate that under the climate change South region tends to have opposite impacts relative to the North Central, the major maize production region in the United States. The results imply that one region’s losses can be partially offset by the other region’s gains. The different responses imply that the South region could provide potential risk mitigation to climate change within the United States and could help the nation and the world maintain maize supply stability. The results gained from this research could be used as cost-efficient climate change risk mitigation strategies for other agricultural commodities in other countries. They can also be used for public policies and advanced risk mitigation and diversification programs, and are expected to contribute to the sustainability of agriculture and the stability of international crop market price in the United States and the world.
