The question I asked was about cost/benefit trade offs of organic and indeed as the linked article indicates, what are the trade offs with how the math adds up. I am not pre-supposing that a switch to organic is even desirable like this comment above.
For instance, if without inorganic fertilizers, yields plummet 20-30%, does that mean we need more forest land converted to farming tonkeep people fed? Do 20-30% more people have to work in agriculture vs today and stop working in cities? What would that do to urban services? What similarly are the trade offs from using fertilizers for land? What happens over time?
If there are good research papers that explore the total system costs and economic impacts?
From the article linked in the parent comment, the failure was very well predicted by it sounds like basically everyone who knew anything about agriculture. And that prediction was based entirely on basic facts about agriculture rather than any "how to get there" effects like you're saying caused it to not work.
Switching suddenly, and by means of a ban -- what could go wrong?
A free-market gradualistic solution would be to cap pesticide and fertilizer imports and auction licenses to buy them.
