The Project on Diversity in the Sierra Tarahumara (PDST) is an international, multidisciplinary, and multicultural research project focused on understanding the interrelationships among the biological, cultural, and linguistic diversity of the Sierra Tarahumara region of northern Mexico. It is based on partnerships established in 2000 among seven indigenous communities in the Sierra Tarahumara and a number of research and educational institutions and non-governmental organizations in Mexico and the United States.
This long-term project, begun in 1992, has focused most recently on the Indians of northern Mexico from the time of European contact to the present. Involving both field research among the Raramuri and archival research in Mexico, the United States and Europe, this project is part of a broader study of the social and cultural history of northern Mexico, which in turn is directed toward developing general social theory regarding the creation and transformation of sociocultural systems.
