タイトル：Empirical study on the effects of climate change on pest damage, rice yield and quality

要旨：This paper shows the impact of climate change directly on the yield and quality of rice production and indirectly on the risk of pests with Japanese prefecture data. Many studies have been conducted to identify the impact of temperature on agricultural production and evaluate adaptation measures to mitigate adverse effects.However, these previous studies have not explicitly clarified the effects of temperature on crops through pest damage. This study aims to divide the impact of temperature on yield and quality into two pathways, through pests and diseases and other pathways, for rice, and to clarify the relative magnitude of the former pathway to determine its effectiveness as an adaptation measure. We find that an increase in the number of days in the high temperature zone directly reduces yield and quality. Furthermore, higher temperatures reduced yield and quality by increasing the number of pests and increased yield through the reduction of blast diseases due to fewer cold summers.
