I would modify that last statement to be "not letting your social agenda affect your research, your report or the your release of either" (or something more compact that gets the same point across). Very few foundations fund research out of the goodness of their hearts, so most of the time (if not *all* of the time), their research is structured specifically to give them what they want (e.g. wording survey questions a specific way). Or if that's not possible, they cherry pick data. Or they simply don't release their findings, if it turns out it won't help their cause.
Anyway, the links in the parent post show some incredible stuff, and pretty much all the scientific criticism I can find is led by one man, Dr. David Briske from Texas A&M. So we have one guy with extensive credentials that says it works, one guy with extensive credentials that says it doesn't, and a slew of others who have tried it (or something similar) with varying results. I'd like to see Savory get a bigger tract of land and a larger herd to see if it can scale. Same with the permaculture stuff: we've got deserts right here in the US, let's see what these guys can do.
