Set 2 www.climatefresk.org 8 Agricultura nu emite mult CO 2 , dar emite o cantitate semnificativă de metan (bovine, câmpuri de orez ) și de oxid de azot ( îngrășământ ). În total, dacă este inclusă despădurirea indusă , aceasta este responsabilă pentru 25 % din gazele cu efect de seră .

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

Consequences

Despădurire

Agricultură

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

Combustibili fosili

Agricultură

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.
Emisiile de CO2

Agricultură

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

Agricultură

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

Agricultură

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).
Biodiversitatea terestră

Agricultură

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

Wrong causes

Biodiversitatea terestră

It would be more logical to link to agricultural yields.
Scăderea randamentelor agricole

Scăderea randamentelor agricole

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