| Climate change can directly affect crop production due to the increases of CO2 and temperature, and indirectly via weather variability especially rainfall. Sugarcane is important crop for Thailand, and large proportion are planted in Northeast of Thailand. Therefore this investigation is conducted to evaluate the impacts of climate change on yield of sugarcane in this region from 2010 to 2049, using ECHAM weather data downscale to 20x20 km by PRECIS as input to CANEGRO crop model in DSSAT program. Results showed that climate change has small effect on long term changes in sugarcane production. However average yield is highly variable, both spatially and temporally. Spatial variability is largely due to both soil and weather while temporal variability is... |
