This study assessed the impact of climate change on wheat production for ethanol in southern Saskatchewan; Canada. The DSSAT-CSM model was used to simulate biomass and grain yield under three climate change scenarios (IPCC SRES A1B; A2 and B1) in the 2050s. Synthetic 300-yr weather data were generated by the AAFC stochastic weather generator for the baseline period (1961-1990) and scenarios. Compared to the baseline; all three scenarios increase precipitation every month except July and August and June (A2 only); when less rains are projected. Annual air temperature is increased by 3.2; 3.6 and 2.7 oC for A1B; A2 and B1; respectively. The model predicted increases in biomass by 28; 12 and 16% without the direct effect of CO2 and 74; 55 and 41% with combined effect (climate and CO2) for A1B; A2 and B1; respectively. Similar increases were found for yield. However; the occurrence of heat shock (>32oC) will increase during grain filling under climate change conditions and could cause severe yield reduction; which is not simulated by DSSAT-CSM; therefore; the yield could be overestimated. Several measures such as early seeding must be taken to avoid heat damage and take the advantage of projected increase in precipitation.
