Cause

Asa aman-draharaha ataon'ny zanak'olombelona

Asa aman-draharaha ataon'ny zanak'olombelona

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

Consequences

Fandripahana ala

Fambolena sy fiompiana

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

Fambolena sy fiompiana

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.

Fambolena sy fiompiana

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