I would only add one anecdote.
I grew up on a potato farm in Prince Edward Island. Recently, I was home and the UPEI was doing its scan of the province. Since the turn of the century, it has seen about 30% more forest in P.E.I. than there was earlier in the century. That is because of innovation, mechanization, fertilizer and better varieties, allowing farmers to leave their less productive land to create forests, and doing more with the land they're already farming.
It's putting more land back into green space, because all of these tools working together provide the most efficient agriculture.
