8 - Landbruk

Landbruk 8
Set 2 www.climatefresk.org 8 Landbruket slipper ikke ut mye CO 2 , men står for store metan - (fra kyr og rismarker) og nitrogenoksidutslipp (fra gjødsel). Totalt står landbruket for 25 % av klimagassutslippene hvis vi inkluderer utslippene fra avskoging til landbruksformål.

Menneskelige aktiviteter

Menneskelige aktiviteter

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

Consequences

Avskoging

Landbruk

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

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

Other possible consequences

Fossile brensler

Landbruk

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-utslipp

Landbruk

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

Landbruk

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

Landbruk

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).
Biologisk mangfold på land

Landbruk

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

Wrong causes

Biologisk mangfold på land

Biologisk mangfold på land

It would be more logical to link to agricultural yields.
Nedgang i avlingsutbyttet

Nedgang i avlingsutbyttet

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