A colleague of mine comments that while some of the increases in yield are obvious (Russia, Canada), others are less so (Kenya? Bangladesh?). Bangladesh will presumably be offset by declining agricultural area. The decreases are more profound as they include the eastern half of China, north India, Brazil and the Midwestern U.S., i.e., the breadbaskets.
Obviously these types of macro projections are only as good as the bottom-up science supporting them, but the latest research does not paint a promising picture.
