This just popped up in one of my news feeds and I thought I would share. Though this describes efforts far less ambitious than a typical permaculture set-up, it’s this kind of research that can move the needle on big ag practices and regulations and funding at the nation scale. Plus, it’s ammunition in talking with skeptics or people new to the concepts. I particularly like the fact that they looked at food security separately from yield. It gets a little dense, but is worth reading to the end.
