32 - Decline in Agricultural Yields

Decline in Agricultural Yields 32
Set 5 www.climatefresk.org 32 Food production can be affected by temperature, droughts, extreme weather events, floods and marine submersion (e.g. the Nile Delta).

Causes

Rising Temperatures

Rising Temperatures

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.
Terrestrial Biodiversity

Terrestrial Biodiversity

Bees and worms are indispensable to agriculture.

Other possible causes

Carbon Sinks

Carbon Sinks

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.
Forest Fires

Forest Fires

Generally forests burn better than wheat fields.

Wrong consequence

Agriculture

Decline in Agricultural Yields

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