BACKGROUND: Rice production by the current stand-ard cultivation method is predicted to decrease due to global warming. It seems that there has been a strong warming trend in Hwaseong-si, Gyeonggi-do. This study attempted to understand the climate change in Hwaseong- si, Gyeonggi-do and to analyze the effect of climate change on rice production. METHODS AND RESULTS: The statistical and phys-icochemical analyses were performed using the rice culti-var ‘Chucheongbyeo’ yields grown at the rice paddy field plot in the Gyeonggi-do Agricultural Research and Ex-tension Services and the weather data measured in near the rice paddy plot. CONCLUSION(S): There was no significant difference between the average rice yields per area in 2000s (2001~ 2010) and 2010s (2011~2020), but the rice yield varia-bility was greater in 2010s than in 2000s. The mean, mini-mum, maximum temperature, and the sunshine hours were evaluated for the correlation with the rice yield. The understanding of climate change in Hwaseong-si, Gyeonggi-do and the major weather factors affecting changes in rice yield, presented in this study, would en-hance scientific understanding of regional climate change, and improve rice cultivation management.
