This is one of the greatest threats to humanity. Declines in agricultural yields have already led to conflicts in Rwanda and Syria.
7Causes
In northern countries, a little increase in temperature can lead to better yields, but in southern countries, it's the contrary: Any degree warmer is a decrease in yields.
Bees and worms are indispensable to agriculture.
3Consequences
La baisse des rendements agricoles peut avoir des implications importantes sur les inégalités, affectant non seulement les revenus des agriculteurs, mais aussi l'accès à la nourriture, à l'emploi et aux ressources.

2Other possible causes
Studies have shown that yields increase with increased CO2, but that the nutrient content of vegetables is reduced as a result, because trace elements are not more abundant when yields increase.
Generally forests burn better than wheat fields.
1Wrong consequence
Yes, the yield decline does affect agriculture, but the agriculture card is here to stand for one of the causes of GHG emissions.
