It’s all about the Panama Canal on this episode of the Cultures of Energy podcast! Dominic and Cymene sing Van Halen and share tales of self-sabotaging students and then (13:58) the phenomenal Ashley Carse joins us to talk about the Panama Canal research that culminated in his book, Beyond the Big Ditch (MIT Press, 2014). We learn about the early 20th century geopolitics that led to the canal zone and how it helped create the state of Panama. We move from there to the world-making powers of empire and transportation, Panama as a logistics hub, who the “Zonians” are, Panamanian hydropolitics, and growing concerns about drought’s impact on both canal operation and the nation’s future. Ashley shares with us some of the crazier schemes the U.S. and Panamanian governments have come up with over the years to improve the canal and explains how aspects of “nature” like forests and rivers have been made into canal infrastructures. We turn then to his new work on dredging and sediments. That gets us to urbanization and the global shortage of sand, transoceanic shipping, and the deepening of harbors to accommodate still more massive ships. We conclude by returning to the Panama Canal, its retrocession to Panamanian control and subsequent life as a space of post-imperial nostalgia. Listen on! PS Also, we researched it and the Van Halen song has nothing actually to do with Panama. It’s about David Lee Roth’s car. But still it’s fun to sing #noregrets.
