Crop models can play a role in this agricultural management decision making process to cope with drought and other natural disasters. Crop simulation models are designed to imitate the behavior of a plant system. These models separate yield prospects into components due to changing weather trends, genetic improvements, and improved technology. Simulation modeling is increasingly being applied in research, teaching, farm and resource management, policy analysis, and production forecasts. Crop simulation models can be used to simulate the drought-reduced crop yields, but a number of issues limit operational applications.
