My research traces the historical roots of several volatile land conflicts currently unfolding in northern Uganda’s Acholi region. By applying a longue durée lens within a political ecology framework, I analyze these contemporary land conflicts as part of the enduring legacy of colonial-era environmental engineering through sleeping sickness control and wildlife conservation in the Acholi region. The project relies on ethnographic research in the districts of Gulu, Nwoya, and Amuru, as well as on archival work in collections in Uganda, the U.S., and the U.K.
