Assessment and mapping of climate change impacts on spring wheat yield in Southern Saskatchewan using DSSAT and high-resolution RCM projections.

ABSTRACT: Climate change presents both potential benefits and drawbacks for crop production in Canada. An assessment and mapping of future climate change impacts on spring wheat yield in Saskatchewan is crucial because the province largely accounts for Canada's share of the global wheat market. We applied ten climate change scenarios (high-resolution (0.22°) regional simulations) to the CERES-Wheat module of the Decision Support System for Agro-technology Transfer (DSSAT) model using a historical baseline period (1975-2004) and three 30-year future periods: near (2010-2039), middle (2040-2069), and far (2070-2099). The model showed high accuracy with d-values always higher than 0.75 for the calibration (d-value = 0.84) and the validation (d-value = 0.82) periods. Furthermore, the model showed a rema
