Humans as geomorphic agents: Lidar detection of the past, present and future of the Teotihuacan Valley, Mexico.

As humans are the primary geomorphic agents on the landscape, it is essential to assess the magnitude, chronological span, and future effects of artificial ground that is expanding under modern urbanization at an alarming rate. We argue humans have been primary geomorphic agents of landscapes since...
