Challenges of Climate Change Flashcards
Why is the use of summer fallow acres decreasing
one of worse practices used in earlier farming that is decreasing because of new chemical control options and no till systems
why should we focus on innovation and productivity instead of the environment in Canada
We account for 1.6% of global emissions so we wont make much of a difference. Plus, if we aren’t economically sustainable, we can’t be environmentally sustainable
Agriculture accounts for ____ of global emissions
1/4
Agriculture accounts for ____ of GHG emissions in Canada
16%
What do most stats not take into account when calculating GHG emissions from Ag
the amount of carbon sequestered from the crops
What Provinces are net carbon sinks in crop production and which are not
Saskatchewan and Alberta are, Manitoba is not
How much have net prairie emissions have decreased and does this pass the 30% requirement for 2030
Decreased by 53%, which surpasses requirement
What is the only way to achieve methane pledge for cattle ranchers
Pay farmers to kill 3, 162,600 head of cattle
What is the problem with carbon sequestering by Saskatchewan forests
Forests are mostly dead trees, which produce large fires and release a lot of GHG into the air
Climate change impact for ag
Factors such as precipitation, temp, extreme weather events, and seasonality changes increase chance for erosion
T/F: there is not scientific proof that we are in a climate crisis
T
Paris Climate Commitment
Agreement that requires countries to lower GHG emissions by 26-28% below 2005 levels and reduce CO2 emissions by 120 million metric tonnes per year
What is the assumed depth that soil is thought to be able to sequester CO2 in Ag Canada and Ohio State University
Ag Canada - 6-8 inches
Ohio State University - 3 feet
