If those farming techniques are so vastly different, then how is applying a top-down solution dreamed up by a researcher going to help? What will work for one won't work for another.
They can farm just fine, on the farm they're used to, in the country they're used to. Why don't you understand this? Take a British farmer, someone who has only farmed on British soil, and plonk them in Afghanistan, and tell them to set up a farm there. They wouldn't have a clue. How about if you got a farmer from the paddy fields in China and got him to come over here and farm rapeseed? Not a chance. Which is what I said about your argument like being about an IT person knowing everything about IT simply because he knows his own segment of the market.
