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.
Facilitation advice
Local or global impacts
It may be interesting to differentiate between local and global causes. Local causes are:
More global causes are:
Correction
Causes
- Temperature Rise
- Terrestrial Biodiversity
- River Flooding
- Droughts
- Freshwater Resources
- Marine Submersion
- Cyclones
Consequences
Other possible links
Other causes
- 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.
