Media are all atwitter about a new Nature study by researchers at McGill University and the University of Minnesota that compares organic and conventional yields from 66 studies and over 300 trials. In extrapolating the study's findings to the charged question of how to feed the world, more than a few got it all wrong.
The core finding of the study is that “yield differences [between organic and conventional] are highly contextual, depending on system and site characteristics.” In other words, sometimes organic does better, sometimes conventional does. In fact, the sheer variety of comparisons led Mother Jones columnist Tom Philpott to observe that the study “like a good buffet… offered something for every taste.”
