Geoarchaeology is traditionally concerned with reconstructing the environmental aspects of past societies using the methods of the earth sciences. The field has been steadily enriched by scholars from a diversity of disciplines and much has happened as the importance of global perspectives on environmental change has emerged. Carlos Cordova, provides a fully up-to-date account of geoarchaeology that reflects the important changes that have occurred in the past four decades. Innovative features include: the development of the human-ecological approach and the impact of technology on this approach; how the diversity of disciplines contributes to archaeological questions; frontiers of archaeology in the deep past, particularly the Anthropocene; the geoarchaeology of the contemporary past; the emerging field of ethno-geoarchaeology; the role of geoarchaeology in global environmental crises and climate change.
