Card #32: Decline in Agricultural Yields

En-en adult card 32 front.png

Food production can be affected by temperature, droughts, extreme weather events, floods and marine submersion (e.g. the Nile Delta).

Explanation

This is one of the greatest threats to humanity. Declines in agricultural yields have already led to conflicts in Rwanda and Syria.

Facilitation advice

Local or global impacts

It may be interesting to differentiate between local and global causes. Local causes are:

More global causes are:

  • Carbon sinks Studies have shown that yields increase with increased CO2, but that the nutrient content of vegetables is reduced. Indeed, trace elements do not become more abundant when yields increase.

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