Abstract

This study aimed to analyze the impact and risk of climate change on wet season rice production in irrigated areas of Northeastern Thailand. The Feasible Generalized Least Squares (FGLS) was applied to estimate the rice production function. By using the panel data on rice production from 19 provinces in the northeast classified by irrigation area of wet season rice (2002–2020),  the results of the study showed that Area harvested, Trend Time, Cumulative Precipitation, and Average Temperature had a positive effect on the yield of wet season rice. At the same time, they were risk factors for rice production variance. On the other hand, rice production in the irrigated area depended on accumulated rainfall and average temperature, which had a negative impact on the wet season rice production and there was a statistically significant increase in the risk of variation in rice production. When considering dummy variables representing cumulative rainfall events exceeding requirement, there was a negative effect on rice yield. At the same time, there was a statistically significant increase in the risk of variance in rice production in all three cases. This study suggests that the characteristics of areas receiving water from irrigation have differentially influenced rice crop yield.
