From: Two-thirds of global cropland area impacted by climate oscillations
Crop productivity sensitivity to oscillation indices. Sensitivity of crop productivity to changes in a ENSO, b IOD, and c NAO indices at the FPU level. The linear relationship was concluded to be significant based on the p-value (<0.1, parameterized, see Methods section) of Pearson’s correlation coefficient. Note that the areas where Pearson’s correlation between reported and simulated crop productivity is not significant (p > 0.1) are striped
