Effects of climate change on agricultural meteorological disaster and crop insects diseases

Climate changes result in warming air temperature and frequent perturbations in precipitation and along with extreme weather events, which is the great threat to the safety of agricultural production. This paper summarized the occurrence and development trends of agricultural meteorological disaster, and new changes in kinds of crop insects and agricultural meteorological disaster base on previous research results and on the data from “Chinese Agriculture Yearbook” published by National Bureau of Statistics. The results showed that most of agricultural meteorological disaster and crop insects became severe with climate warming, in particular, the high frequency of extreme weather events as a great threat to the safety of food production. The future agricultural disasters and pests will be even more frequently, which make agricultural production unstable, and a positive response should be taken.
