Fig. 7
A similar analysis as in Fig. 6, except the crop-cut data are compared to farmer surveys rather than to regional government statistics. The locations of the crop cut and farmer survey data are shown in (a). (b) A summary of the yield biases for the ten crops with sufficient data to make comparisons between the crop cuts and farmer surveys. The positive yield biases across all crops indicate that the yield estimates based on farmer surveys are overestimates relative to the crop cut data. However, the mean bias of +20% is smaller than the yield bias in Fig. 5.
