Allison and I are admittedly nerds in many ways. When we get interested in something we'll read at least 5 books about it. So having our librarian friend find scholarly articles on Permaculture for us is definitely more exciting than it should be. She sent us an article called Permaculture for Agroecology: Design, Movement, Practice and Worldview by Rafter Sass Ferguson & Sarah Taylor Lovell, published in 2012. It was unusual in that it was an academic article written by people outside the Permaculture world looking, mostly, at what Permaculture might have to offer the transition to Agroecology.
