| Résumé | (disponible en anglais seulement)
A changing climate presents Canadian food producers with a number of opportunities as well as risks that will challenge the food supply industry, particularly
in the short term. Key findings include:
Impacts of climate change differ significantly among the sectors discussed (agriculture, fisheries and non-commercial food supply), but common challenges did emerge, including threats to food supply from
increased losses from invasive pests and diseases, and risks to the transportation systems upon which the sectors rely.
The net medium-term outlook is for a likely modest increase in agricultural food production. Longer and warmer growing seasons
would allow higher-value warmer-weather crops to be grown further north (where soil conditions permit), lengthen outdoor feeding seasons for livestock, and allow the maple syrup industry to expand northward. However, there will likely be new pests
and diseases, as well as more severe outbreaks of current ones, increased growth of weeds, and other challenges that could negatively affect production and require timely adaptation (e.g. improved water efficiencies and changes in crop management
practices).
Northern and remote communities are likely to see great changes in their environment - some will ease food security concerns while others could exacerbate already decreasing country food stocks and difficulties in delivering supplies
into isolated areas.
Canada is expected to remain a net exporter of aquatic foods at the aggregate level, with total biomass of production from wild-capture fisheries in Canada expected to increase due to climate-induced shifts in fish
distributions. Regional impacts from invading species, physical habitat changes and societal responses to shifts in availability and access to aquatic food resources will gradually determine future patterns of use and overall economic implications.
Aquaculture has a greater scope for adaptation to climate change than other fisheries, making it less vulnerable and better positioned to take advantage of opportunities than capture fisheries, and subsistence fisheries in
particular. |
