8 - Landwirtschaft

Landwirtschaft 8
Set 2 www.climatefresk.org 8 Landwirtschaft emittiert zwar nur wenig CO 2 , jedoch ist sie verantwortlich für den Ausstoß von großen Mengen Methan (Rinder, Reisfelder) und Distickstoffmonoxid (entsteht durch Stickstoffdünger), auch genannt Lachgas. Insgesamt ergeben sich so 25 % der THG - Emissionen, wenn wir die induzierte Entwaldung mit einbeziehen.

Cause

Menschliche Aktivitäten

Menschliche Aktivitäten

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

Consequences

Entwaldung

Landwirtschaft

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 Brennstoffe

Landwirtschaft

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-Emissionen

Landwirtschaft

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

Landwirtschaft

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

Landwirtschaft

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).
terrestrische Biodiversität

Landwirtschaft

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

Wrong causes

terrestrische Biodiversität

terrestrische Biodiversität

It would be more logical to link to agricultural yields.
Rückgang der Ernteerträge

Rückgang der Ernteerträge

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