Geographer Carl Ortwin Sauer demonstrated through his work and writings that landscapes are the long-term contingent product of interactions between natural processes and cultural forces. In this lecture, Patrick Kirch, Professor of Anthropology and Integrative Biology, University of California, Berkeley, applies the concept of landscape to the islands of Polynesia. Drawing upon recent multi-disciplinary research, Kirch shows how certain natural properties of islands shaped the course of cultural and social evolution of island peoples, at the same time that cumulative effect of human actions irreversibly altered island environments.
