A crop's yield is the amount of food grown per unit of land.
There are 2 main reasons to want to increase crop yields:
- Produce more food - which could help prevent hunger.
- Use less farm land - which could help prevent deforestation.
Yields can be increased through innovation, and/or by simply growing different crops.
The current situation
Crop yields are generally higher in richer countries.
Conventional agriculture
Characteristics include:
The first 3 are generally considered the reason that rich countries get higher yields. Whereas monoculture might actually decrease yields due to less resiliance against pests (and the pesticides & GMOs are designed to compensate for this).
There may be alternatives to conventional agriculture, which get higher yields. This wiki doesn't have enough information on this yet.
Unanswered questions
Materially speaking, what is lacking in places with low crop yields?
Is it true that polyculture can produce higher yields than monoculture? If so, why isn't it more common?
How much nitrogen can legume crops 'fix' into the soil? How does it compare to the amount of nitrogen needed to maximize grain yields?
