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 [[crop choices|growing different crops]]. | |||

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. | |||
