Current research

Thegn is a member of a National Science Foundation funded project investigating the evidence for terrestrial resource dynamics and societal collapse on Rapa Nui. The project includes researchers from Rapa Nui (Haoa), the United States (Stevenson, Chadwick, Vitousek, Puleston), and New Zealand (Ladefoged) and is focusing on climate change, environmental degradation, and subsistence transformations to develop an empirical assessment of how these may, or may not have, influenced pre-European contact societal collapse on the island.

In addition, Thegn is a member of a National Science Foundation funded research team investigating the ecodynamics of windward and leeward Kohala on the Big Island of Hawai’i. This project is multidisciplinary, and involves collaborative fieldwork by archaeologists (Kirch, Graves, McCoy, and Field), ecologists (Vitousek), soil scientists (Chadwick), botanists (Hotchkiss), and demographers (Tuljapurkar). Thegn’s focus is on the leeward Kohala rain-fed agricultural fieldsystem, where he is documenting the relationships between agricultural development, sociopolitical transformations, and ideological shifts.

Thegn’s Hawai’i research also involves a Royal Society of New Zealand Marsden funded project to refine a predictive model of the distribution of pre-European contact intensive rain-fed agriculture. A current GIS-based model is being tested and refined with archaeological, geochemical, and remotely sensed data. The refined model will form the basis for further agent-based modelling of the Hawaiian socio-political responses to differential production potentials. The research is in collaboration with Vitousek, Chadwick, and Kirch, and will provide insights into the constraints that limited expansion of intensive rain-fed agriculture, and investigate alternative behaviours for increasing resource bases such as warfare and marriage alliances.

Finally, Thegn is collaborating with McCoy on a research project in the Bay of Islands, New Zealand, investigating the ecological and cultural motivations of territoriality and warfare. The project includes archaeological field and laboratory research to model interaction via obsidian access/trade routes; the timing, location, and scale of fortification construction; and agricultural productivity. The research will provide a better understanding of why people fight over status, resources, and land.
