Impacts of Climate Change to British Columbia Agriculture

Some of the overall impacts of climate change for BC agriculture have been identified as follows: http://www.bcagclimateaction.ca/overview/why-adaptation/ 

  • More frequent occurrence and severity of summer drought; water shortages in more regions. Hotter and drier summers. 
  • Decreased snowfall in alpine areas leading to reduced snowpack and to water shortages 
  • Increased precipitation (frequently through more extreme events) and subsequent vulnerability to flooding, erosion, nutrient loss. Wetter and milder winters. 
  • More frequent and intense “extreme” weather events (wind-storms, forest fires, hail, droughts and floods) 
  • Increase in growing degree days (heat units) and a longer frost free season. Hotter summers with milder winters. 
  • Potential for broader range of viable crops in some regions. Milder winters. 
  • Increase in pest and disease pressure due to winter survival of pests.
