The project proposed here will discuss the German colonial experiences in a few regions of Africa through a historical research on several sources collected over the past three years from universities, libraries and public as well as private archives in Brazil, Germany and Namibia. The research aims to study the ecological and cultural adaptation of Germans in tropical and subtropical regions as well as the relationship between Overseas German communities and African peoples. The research will focus on the ecological impact of the colonial economy in the various ecosystems of Equatorial Africa, East Africa and South-West Africa (now Namibia). By means of a connected histories approach and a global perspective, this research aims at understanding the circulation and sharing of German colonial experiences and its relationship to other colonial experiences.
