The case for super farms ignores two things.
1. It is increasing the case that monoculture proves to be a bad thing, in farming like anything else. Moving to larger scales of monoculture merely increases the likelihood that diseases and pests will claim the entire huge crop. Mixed cultures are much better from that perspective.
2. A “super” farm is only possible with large amounts of cheap energy. The costs of energy are rising and will continue to do so.
I also heard on the radio this morning that super farms will create jobs because 1 man can now do what 10 used to. Not sure how that works?
What seems to be more useful is the opposite: small, human scale organic farms with mixed crops, probably designed using permaculture principles. This would seem to be a more productive way forward to produce more food, of different types, and more employment, while using less energy.
