Abstract
Climate warming has prolonged the optimization of crop-growing seasons, shortened actual growth periods, and changed crop-planting boundaries. It also has boosted crop yields in certain regions while compromising crop quality and affected the occurrence of meteorological disasters and pest diseases damage, which has resulted in reduction in grain yield. Crop production systems will evidence more sensitivity to climate change in future; for example, with an increase of 1°C in temperature, the average growth period will be shortened by 17 days for winter wheat and 7–8 days for maize and rice. Of course regional differences will exist. Climate change will threaten crop yield stability and affect crop quality. Vulnerability will be addressed in regard to extreme climatic events, which include reducing exposure and improving adaptive capacity, because the exposure of rain-fed agriculture is greater than that of irrigated agriculture. Therefore, we propose three suggestions to reduce the vulnerability of crop p...
