Annette Kehnel joins Jana Byars to talk about The Green Ages: Medieval Innovations in Sustainability (Brandeis University Press, 2024). A fascinating blend of history and ecological economics that uncovers the medieval precedents for modern concepts of sustainable living. In The Green Ages, historian Annette Kehnel explores sustainability initiatives from the Middle Ages, highlighting communities that operated a barter trade system on the Monte Subiaco in Italy, sustainable fishing at Lake Constance, common lands in the United Kingdom, transient grazing among Alpine shepherds in the south of France, and bridges built by crowdfunding in Avignon. 

Kehnel takes these medieval examples and applies their practical lessons to the modern world to prove that we can live sustainably--we've done it before! From the garden economy in the mythical-sounding City of Ladies to early microcredit banks, Kehnel uncovers a world at odds with our understanding of the typical medieval existence. Premodern history is full of inspiring examples and concepts ripe for rediscovery, and we urgently need them as today's challenges--finite resources, the twilight of consumerism, and growing inequality--threaten what we have come to think of as a modern way of living sustainably. This is a stimulating and revelatory look at a past that has the power to change our future.
