The CERES-Wheat & Rice model was tested in Haryana, India to see how well it predicts crop yields in changing climate conditions. The model was adjusted to match real-life data on crop growth and yield. By comparing the model's predictions with actual measurements, the researchers found that it can accurately simulate crop yields for wheat and rice in different farming scenarios. The model's error rate was less than 10%, showing its usefulness for assessing climate risks in the region.
