8 - Poľnohospodárstvo

Poľnohospodárstvo 8
Set 2 www.climatefresk.org 8 Poľnohospodárstvo nevypúšťa veľa CO 2 , ale je zodpovedné za veľké množstvo metánu ( dobytok , ryžové polia ) a oxidu dusného ( umelé hnojivá ). Celkovo predstavuje 25 % skleníkových plynov ak počítame aj spôsobené odlesňovanie .

1
Cause

Ľudská aktivita

Ľudská aktivita

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

Consequences

Odlesňovanie

Poľnohospodárstvo

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

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

Other possible consequences

Fosílne palivá

Poľnohospodárstvo

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 emisie

Poľnohospodárstvo

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

Poľnohospodárstvo

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

Poľnohospodárstvo

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).
Suchozemská biodiverzita

Poľnohospodárstvo

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

Wrong causes

Suchozemská biodiverzita

It would be more logical to link to agricultural yields.
Pokles poľnohospodárskej úrody

Pokles poľnohospodárskej úrody

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