8 - Jordbruk

Jordbruk 8
Set 2 www.climatefresk.org 8 Jordbruket släpper inte ut så mycket koldioxid, men däremot stora mängder metan (från boskap och risfält) och lustgas (från gödsel). Totalt står jordbrukssektorn för 25 % av de globala växthusgasustläppen, om en räknar med utsläpp från avskogning.

Cause

Mänskliga aktiviteter

Mänskliga aktiviteter

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

Consequences

Avskogning

Jordbruk

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

Fossila bränslen

Jordbruk

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.
Koldioxidutsläpp

Jordbruk

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

Jordbruk

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

Jordbruk

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).
Landlevande biologisk mångfald

Jordbruk

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

Landlevande biologisk mångfald

Landlevande biologisk mångfald

It would be more logical to link to agricultural yields.

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