You are posting literal propaganda from the biggest agro lobbyist. That number is about the "Danish food cluster". That is all food related business output. Enzyme production and such. They have tried for a long time to conflate the farming sector with the whole food industry to muddy their importance.

i admit that i haven't read the sources listed here

and also that this source is probably biased toward minimizing the numbers while your source might be pulling in the other direction. the true number is probably somewhere in between and depends on what you include. like, could the raw products be imported instead and the refined in Denmark without those 22% taking a hit?
