The problem is, it's hard to find data to refute his claims (I did my best, but to an insider, there may be a faint whiff of the barnyard about some of my reply). We just don't collect data. What do we answer when a farmer asks, "How much more money or produce, or less erosion, will your system get me?" That we just know it works better? Does anyone have any numbers? I've looked at a lot of Pc sites in North America, and I haven't seen one where people are measuring yields.
So are we justified in saying that this stuff works? Or is permaculture just for those, as Williams says, "who do not require optimal solutions to pressing agricultural and ecological problems"?
If anyone's got any hard numbers, or other reputable data, please share them. If not, it points to a huge lack in permaculture, and we should get busy setting up trials and getting reliable data instead of just banking on Bill's wild claims. Without data, more folks like Williams will erode permaculture's credibility.
I've also had inquiries from a researcher who wants yield data from permaculture farms for a thesis. If anyone has these, let me know.
