Abstract
Several studies have addressed the potential impact of climate change on soybean production in the southeastern USA by coupling crop models and climate models. However, there are several limitations to the approach used in prior studies which require improvement. The overall goals of this study were to evaluate the CSM-CROPGRO-Soybean model for local conditions in Georgia, to determine suitable GCMs for representing future climate patterns, and to evaluate potential adaptation strategies for soybean production in the southeastern USA by analyzing the effects of climate change on soybean production for the next 40 years. The results of this study showed that soybean number of days to maturity decreased due to the increase in air temperature. The projected increase in CO2 concentration benefited yield, while the projected change in precipitation was the main factor that determined yield. Potential adaptation strategies were evaluated for soybean production in the southeastern USA.
