This week, Bertie Harrison-Broninski speaks with Professor Annette Kehnel, Chair of Medieval History at the University of Mannheim. Kehnel gives us a potted history of sustainability and argues that sustainable practices have existed throughout history, yet our modern collective memory is influenced by ideas of resource exploitation introduced in the 18th and 19th centuries.  

Annette Kehnel is currently a visiting fellow at the University of St. Gallen in Switzerland. She is the author of The Green Ages: Sustainable Practices, winner of the 2021 NDR Book Prize. Its English translation by Geshe Ipsen has been shortlisted for the 2025 Schlegel-Tieck Prize.
