In this chapter the ideas of government making up Foucault’s triangle are applied to what he called the “witches’ brew” of practices. I will use geographer Roderick P. Neumann’s ethnography of park protection projects in Tanzania, Africa, as an example of sovereignty and the environmental historian Christophe Bonneuil’s study of settlement schemes (1930–70) in tropical Africa as an example of discipline. I use two outstanding examples of governmentality and the triangle as a whole. The first is Donald Moore’s ethnography of colonial and post-colonial efforts to improve the population, forests, and the productivity of the land in Zimbabwe. The second is Tania Murray Li’s ethnography of the improving rationale of colonial and post-colonial states in Sulawesi, Indonesia. All four authors use Foucault.
