Maps of estimated maize yields in Nigeria over the period 2002-2021 based on applying the neural network in Fig. 14. Equivalent estimates could be created for any other country (or for all of Africa) using the same neural network approach. The maps are displayed with a transparency layer that represents the estimated cropland area fraction, such that regions with no croplands appear transparent and regions with abundant croplands appear opaque. See Figure S24 in the Supporting Information for the cropland area estimates.
