BACKGROUND: It is known that impacts of climatechange on damage occurrence by insect pests and diseasesare increasing. The negative effects of climate change onproduction will threaten our food security. It is needed thaton the basis of analysis of the impacts, proper strategies inresponse to climate change are developed. METHODS AND RESULTS: The objective of this paper isto estimate impacts of climate change on rice damageoccurrence by insect pests and diseases, using the panalmodel which analyzes both cross-section data and timeseries data. The result of an analysis on impacts of climatechange on rice damage occurrence by pest insect anddisease showed that the damage occurrence by Rice leafroller and Rice water weevil increased if temperatureincreased, and damage occurrence by Stripe, Sheath blight,and Leaf Blast increased if precipitation(or amount ofsunshine) increased(or decreased). CONCLUSION: Adaptation strategies, supplying weatherforecasting information by region, developing systematicalstrategies for prevention of damage occurrence by pestinsect and disease, analyzing the factors of damageoccurrence by unexpected pest insect and disease,enforcing international cooperation for prevention ofdamage occurrence are needed to minimize the impacts ofdamage occurrence on rice production.
