Short summary
Human population growth imposes increasing demands on crop yield (i.e., crop production per unit area). Worryingly, first signs of yield deceleration and stagnation were reported. In our study we show how crop cultivation region, type of harvested organ, pollinator dependency, and life form affect yield growth and/or stability of globally important crops. Our results together advocate for a more diverse agriculture involving the cultivation of different crops with different ecological features.
