8 - Земеделие

Земеделие 8
Група 2 www.climatefresk.org 8 Земеделието е отговорно за емисиите на малко CO 2 и на много метан (говеда, оризища) и на азотен протоксид (торове). Като цяло, това са 25 % от емисиите на парникови газове, ако включим и свързаното обезлесяване.

Cause

Човешки дейности

Човешки дейности

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

Consequences

Обезлесяване

Земеделие

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

Изкопаеми горива

Земеделие

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.
Емисии CO2

Земеделие

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

Земеделие

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

Земеделие

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).
Земно биоразнообразие

Земеделие

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

It would be more logical to link to agricultural yields.
Спад на земеделските добиви

Спад на земеделските добиви

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