Dynamic Sustainability, Resource Management, and Collective Action on Two Atolls in the Remote Pacific

Examples of environmental transformation, the creation of sustainable lifeways, and the development of environmentally aware political forms better our understanding of how peoples build on tradition and environmental circumstance to form novel institutions. Using archaeological data, oral histories, genealogies, radiocarbon dating, and Bayesian modeling, we present a timeline of habitation and land-use patterns on Manihiki and Rakahanga, two remote atolls in East Polynesia. We track socioecological change on the atolls from the time of first colonization ca. AD 1200–1400 through to sustained European contact in the mid-1800s. The findings document and temporally anchor collective action-based processes of landscape transformation, the development of a system of cyclical mass migration aimed at sustainable resource use, and the implementation of a novel dual-chiefdom political system. This demonstrates that new levels of political “complexity” manifest as patterns of shifting hierarchy and novel forms of political and ecological management, and can arise in relation to specific social and ecological challenges in systems of any size. The perpetuation and adaptation of aspects of these traditional institutions can help to maintain the sustainability of populations today in the face of climatic and social change.
