The effects of climate change are being felt across British Columbia. Given that climate is the most important determinant of crop suitability for a given location, climatic change has and will affect which crops can most profitably be grown in BC and where. Crop suitability modelling uses our understanding of growing season requirements, phenological development, and/or critical temperature thresholds for individual crops to determine their suitability across the landscape. Model output using historical and future climate data can help the agricultural sector anticipate the effects of climate change on crop suitability, manage risks and adapt. There are a number of approaches to crop suitability modelling. Agriculture and Agri-Food Canada’s Land Suitability Ratings (LSRS) is used to predict the suitability of commercial field crops across the landscape; recent work using LSRS under a range of future climate scenarios suggests that crop suitability for corn may initially improve in the Fraser Valley up to the mid-century but that increasing temperatures will reverse this trend beyond 2050. Similarly, crop suitability modelling for sweet cherry, driven by modules for dormancy, spring phenology and growing season heat requirements, has shown that recent warming has extended the suitable growing region for sweet cherries northward and upslope; climate projections suggest that the Cariboo region may become available for cherry cultivation by the mid-century. In order to support BC’s agricultural sector into the future, expansion of transportation corridors and irrigation infrastructure will likely be required, as will a comprehensive assessment of the available irrigation water supply.
