Card #32: Decline Agricultural Yields
| Causes | Consequences | |
|
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.

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