Having no time to check up on the sources, I would say that my only objection to the overview of the study is the comparison of "what 'organic' _might eventually_ be able to produce" with conventional agriculture as if it were a static target and presenting current production as if it were a sufficient long-term target. Organic production methods might be able to provide a theoretical caloric output that is equal to 180% of current conventional agriculture caloric output? Well done, but if global population is going to increase by 50% within 50 years this approach is not good enough.
