Does climate change have an impact of vegetable production in Quebec?

Présentation du Symposium Ouranos 2025.

The impact of climate change on irrigation requirements to the periods 2050 and 2080 were predicted for vegetable production in Lanoraie, Qc. The irrigation requirement for potato is predicted to significantly increase by the 2080s compared to the historical period (1997-2021), under the CMIP-6 SSP5-8.5 high emissions scenario. Projected irrigation requirements for squash remained stable. Irrigation treatment significantly impacted the net irrigation requirement, with an Maximum Allowable Depletion set at 50% of Available Water significantly reducing irrigation requirements across all climate periods.
