Service Description: Large yield variations exist across the world, even among regions with similar growing conditions, suggesting the existence of ‘yield gaps’. Here we define a yield gap as the difference between observed crop yields and the potential yield at the same location. It is estimated that bringing the world’s yields to within 95% of their potential for 16 important food and feed crops could increase current production by 58%. Yield gaps were estimated by comparing observed yields to potential yields determined by identifying high-yielding areas within zones, or bins, of similar climate.
