@wraidd here's some good looking info! (I haven't listened to the podcast yet) https://www.thepermaculturepodcast.com/2012/can-permaculture-feed-the-world/
@wraidd replying to be in the thread
@wraidd I've seen some figures that yes, we can. Of course it's more labor intense.
@wraidd It is a very interesting topic. I have not worked on the numbers, my experience and knowledge about the topic says however that the question is a bit wrong. Permaculture are tools and and a way of thinking. With permaculture a lot of people can be fed, however not in the way that the current agroindustry works. We can't turn those huge farms into "permaculture"-farms and expect them to feed the same or more people. 1/2
Permaculture has its strengths in the niches where the "normal" way is not applicable. If we consider more people moving into agriculture, living and working on small scale organic farms using permaculture then IMO yes, all humans from this planet can be fed. But this would mean a total shift from our consumer oriented society into something different.
@wraidd I just read 'Restoration Agriculture' by Mark Shepard, who was a standard farmer and is now an agroforestry/permaculture farmer. He pretty much says yes, we could probably feed even more, but - like other people on this thread have said - it would be more labour intensive. (Which wouldn't necessarily be a bad thing, tbh. Call it 'job creation' and it can be a bonus :) )
@wraidd Just as @Ranunculus I have no numbers at hand, but for me it is just logical that if we treat our organic waste as a resource to improve our soil, there is no reason we can not feed 8 billion people.
