Uh, no. Permaculture produces a fraction of the calories per acre of traditional monoculture agriculture. It is nothing more than an amusement for dilettantes, as is any other system that claims to significantly improve upon the ~12,000 of human experience with field-based agriculture. I'm in the process of converting a 20 acre tract of woods into a "productive" farm via a combination of aquapontics and permaculture, I just don't have any illusions that I'm doing anything other than fucking around for my own amusement.
