Fiche renseignements : Sécheresse

The document details how climate change intensifies droughts through higher temperatures and altered precipitation, leading to severe economic losses in agriculture and hydropower, increased wildfire risks, and public health threats in Canada.

• Climate change is increasing the frequency and severity of droughts globally, with over 40% of global land area expected to experience year-round drying by the end of the century, even under optimistic scenarios.
• In Canada, the Prairie provinces, southern Northwest Territories, parts of interior British Columbia, and most of Ontario are likely to be the most affected by increased drought frequency and intensity.
• Droughts have caused significant economic damage to Canadian agriculture, evidenced by crop insurance payments rising from 890 million dollars in 2018 to 4.9 billion dollars in 2022.
• Drought conditions negatively impact hydropower production and revenue; for example, Hydro-Québec saw a revenue decrease of 866 million dollars in 2024 due to low reservoir levels and reduced exports.
• Droughts exacerbate other environmental disasters, specifically fueling wildfires by drying vegetation and soils; widespread drought was a major factor in the 2025 wildfire season, the second worst in Canadian history.
• Public health is threatened by droughts through degraded drinking water quality, increased risk of waterborne diseases, respiratory issues from wind-blown dust, and mental health challenges such as anxiety and depression among farmers.
• Recommended government actions to mitigate drought risks include proactive planning (such as Alberta's response plan), water conservation policies, improved early warning systems like the Drought Watch tool, and investments in climate modeling for hydropower.
