Research interests
My research interests encompass political ecology, economic anthropology, and historical change in land use.
-
In the 1980s, I conducted field research in western and eastern Kenya focusing on economic aspects of kinship, marriage, gender, and social change.
-
Since 1989, my research and field site is in the Pare Hills, northeastern Tanzania, where I have investigated how long-term changes in land use are related to political-economic processes in regional and world systems. This research also focuses on the historical and contemporary role of how livestock in East Africa as economic and social assets affect land use.
-
I have extended these research interests to a global comparative study of the emergence of intensive cultivation in non-industrial settings, the theory of landesque capital, and the socio-ecological correlates of world-systems and prestige goods exchange with special emphasis on the ivory trade in the Indian Ocean.
-
I also maintain a long-standing interest in Viking Age Scandinavia and the processes of centralization and expansion of Norse political systems.
