Personal Message from the Authors

This collection of articles results from a scientific conference at the TUM Study and Science Center in Raitenhaslach from 20 to 22 March 2019, entitled “Violated Earth—Violent Earth. Causes and Effects of Human’s Misbehavior and Nature’s Power.” Merely by coincidence, this event, featuring several decades of Peter Wilderer’s stimulating sustainability research, concurred with his 80th birthday. Therefore, we, the contributors to this volume, want to take this opportunity and cordially thank our editor-in-chief for his lifetime’s work.
