No problem! They are not so much "permaculture" focused, but more of a holistic view. If you want something on just permaculture, you might want to check out something by Sepp Holzer. He is pretty much considered the granddaddy to modern permaculture. If you are not already, I would also subscribe to /r/permaculture. It is a decent sub with some really helpful links. Sorry about not getting back to you sooner, I do not get on Reddit as much as some.
Sepp Holzer is pretty famous in permaculture circles. He has a book on small farm permaculture and on regreening arid land. He continues to give seminars on permaculture and sustainable agriculture, specializing in marginal land, e.g. high altitude and arid soil.
personally i hate big Agra , and think we should be growing as much locally and decentralized as possible.
