... Before Climate Change Does This is a great article, not only for the ideas it conveys, but for the links to old documents (free!) that describe the reasons for the downfall of many civilizations: erosion! Found references to "permanent agriculture" in the Conquest of the Land report, maybe a predecessor to Bill Mollison's Permaculture! Anyhow excellent reference materials for your library and very interesting reading. https://www.resilience.org/stories/2014-12-01/soil-erosion-may-get-us-before-climate-change-does
check out the book_Dirt_, by David Montgomery 2007 at the library. Covers much of the same topic. all very interesting and fitting to permaculture applications.

Very Cool, I have original copies of both of these books. I received them back in 1970 from one of my horticulture professors because of my beliefs in not disturbing soil for farming or any other reason. I remember him telling the lecture hall that I was expounding on Ideas that, while not ahead of the times, were in fact recognition of historical facts. Pretty awesome to see that they are now available to everyone. Every where in the world that people have created civilizations you can find the evidence of erosion. It is what led to the demise of the Anasazi, and many other pre-history civilizations. In fact I believe that only a few civilizations did not meet their demise by other means.
