The human species is a keystone species in virtually all environments, as a modifier of landscapes that impinges on the other species of the biota as well as contributing the historical development of landforms. The evolution of landscapes is entwined with the evolution of human social systems and specific modes of energy capture from the environment (foraging, farming, mineral extraction, etc.). Scholarship in the 21st century approaches this issue from a wide range of perspectives both scientific and humanistic. Two key themes of current debate are the “anthropocene” and human niche construction. This research network will bring together all IoA researchers current engaged in these topics, and provide venues for interaction and critical comparisons across space and time periods.
