Abstract This article uses digital Geographic Information Systems (GIS) to visualize changing crop choice over time in nineteenth-century equatorial eastern Africa. It maps the locations of crops mentioned in early imperial sources, using contemporary cartographic representations of the region as a base. This enables a novel visualization of changing agricultural potential and vulnerability to climate variability over time. The maps contextualize the growth of commercial and political centers, a series of famines during years and seasons of below average rainfall, and the well-known environmental challenges of the early colonial period.
