Fig. 5.

Spatial distribution of levels of crowdsourced prices of maize and rice in 2019 (top) and 2020 (bottom), relative to mean richness index (MRI) in Kano and Katsina, Nigeria. Colored dots indicate crowd-sourced local commodity prices, ranging from blue (low prices) to red (high prices). The color of each local government area (LGA) indicates the relative level of richness, going from poor (light red) to richer (light blue) than average.
