I don't have a farm but I have a quarter acre of land in london on which I spend a fair amount of time growing vegetables (there are actually 5 of us). We don't have any grass to give you an idea.

The skills are definitely transferrable , particularly time and planning skills. Mathematics and engineering skills are almost vital for success as well.

However the most important things it gives me are peace, tranquility and space to think. I can go for a wander and come back with a fully modelled system and some potatoes :)

All skills gained are valuable in an uncertain future.
