Something I think about a lot is how farming can be done without breaking one's back, figuratively or literally.
People of small stature and many people with physical disabilities are capable of farming. You don't even need advanced technology for this. Simple tools and proper strategic planning can be used to grow food without chronically hurting and exhausting workers.
I think labor minimization is right in line with
permaculture. Don't burn more
energy than you have to, don't disturb the soil more than you have to, don't burn out your employees or your self, etc. Work smarter as they say.
