8 - Landbrug

Landbrug 8
Set 2 www.climatefresk.org 8 Landbrugssektoren udleder ikke så meget CO 2 , men bidrager til gengæld med store mængder metangas (CH 4 , fra drøvtyggere og rismarker) og lattergas (N 2 O, kvælstofgødning). Hvis vi inkluderer skovrydning, bidrager landbruget i alt med 25 % af de samlede drivhusgasudledninger.

Menneskelige aktiviteter

Menneskelige aktiviteter

accounts for 25% of GHGs if we include induced deforestation.

Consequences

Skovrydning

Landbrug

Deforestation is due for 80% to agriculture. It can be considered as a human activity or as a consequence of agriculture of both.
De andre drivhusgasser

The pictures in the background of card 9 should put you on the track!

Other possible consequences

Fossile Brændstoffer

Landbrug

Agriculture does not use much fossil fuel, just enough to keep tractors running. Its carbon emissions are high, bu mainly because of methane and nitrous oxide.
CO2-udledninger

Landbrug

Agriculture does not emit much CO2 except from deforestation. Its carbon emissions mainly come from othe GHGs.
Aerosoler

Landbrug

Spraying crops does result in aerosols and air pollution, but not to the same extent as incomplete combustion from power plants.
Kulstofpuljer

Landbrug

It doesn't matter if this link is not made, but it is true that agriculture can improve storage capacity through photosynthesis. This is the 0.4% principle (if we increased the soil's capacity to sequester carbon by even 0,4%, we would have a significant impact on CO2).
Biodiversitet på land

Landbrug

Here, we are thinking mainly of pesticides (especially Roundup or neonicotinoids). No link with the climate, but an interesting relation to make.

Wrong causes

Biodiversitet på land

Biodiversitet på land

It would be more logical to link to agricultural yields.
Faldende fødevareforsyninger

Faldende fødevareforsyninger

Yes, the yield decline does affect agriculture, but the agriculture card is here to stand for one of the causes of GHG emissions.
