But Agriculture is Different:But Agriculture is Different:Some Realities ...Some Realities ...
Biological process of production is very dependent on climate and weather
Climate variability is a fact of life – risk management
Ag sector generally operates in global markets with narrow margins and limited opportunities to pass costs on to customers

But Agriculture is Different:But Agriculture is Different:Some More Realities ...Some More Realities ...
Process of policy making in agriculture is a shared federal-provincial responsibility
Focus on short term income problemsExpanding exports is seen as a solution;
dealing with climate change is notPerception of agriculture as a polluter
and destroyer of the environment

Benefits to AgricultureBenefits to Agriculture
• potentially more heat units• longer frost free season• increase moisture in some drought
prone areas of Eastern Canada
• CO2 growth enhancement

Concerns for AgricultureConcerns for Agriculture
increased variability in climate raised sea level on the East and
West Coasts increased and decreased soil
moisture in different parts of Canada
more/different weeds and bugs more erosion
