OutlineOutline

But agriculture is different –Elements of climate change and

agricultureBenefits and concerns for agricultureAdaptation opportunities

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
