Crop pest and disease used in this project

The crop pest and diseases survey(CPD) data is a published dataset of aggregated CPD occurrence ratio at the province level of the period from 1980 to 2017. CPD records of National Agricultural Technology Extension and Service Center. This dataset is based on the survey data originating from a bottom-up crop protection network that takes responsibility of surveying the CPD condition and recording the occurrence of CPD. Notably, crop protection only recorded those species of CPD that lead to yield reduction or failure.
