Objective. To validate a simulation model which enables the estimation of wheat (Triticum aestivum L.) production, based on climatic variables in the lower Mayo River basin in Sonora, Mexico. Design/methodology/ approach. The Soil and Water Assessment Tool (SWAT) Crop Yield simulation model was used to estimate productive wheat yields. The model was fed with climatic data for the 1979-2014 period, provided by the National Centers for Environmental Prediction. Subsequently, the results were

The predictive capacity of the model was validated in four of the six Hydrological Response Units with agricultural land in the study area: 26, 27, 28, and 31. Study limitations/implications. The model does not include adaptation measures and future production scenarios based on climate data estimation must be developed. Findings/conclusions. The influence of climate change on wheat production has been confirmed; the predictive model used is an important tool that can be adjusted and adapted to other regions and production systems.
