Crop yield comparisons of maize, rice, soya bean, and wheat around 2010 covering matching 30 arcminute grid cells between our study and Iizumi and Sakai23. Colour bars show the number of grid cells in a specific hexagon (maximum is adjusted to the sample size), r is the Pearson correlation coefficient, n is the sample size, the black line represents no difference, and the orange line is a linear regression fit. Extreme values are filtered out.
