Down to Earth: The Planet to Plate Podcast Quivira Coalition and Radio Cafe

TomKat Ranch manager Mark Biaggi talks about dealing with winter floods, summer droughts, and degraded landscapes––and the process of continual experimentation that leads to dramatic regeneration of damaged land.

66 million years ago an asteroid struck earth, causing the fifth mass extinction of species on earth. With the dinosaurs gone, new species proliferated all over the planet. Now we're in the sixth extinction––this time caused by people. But when did it start? And what happened on on this continent in particular?
Dan Flores' new book, Wild New World: The Epic Story of Animals & People in America, explores the deep history of the North American continent, which was once populated by giant bison and mammoths, massive eagles and condors, ground sloths and dire wolves––all of whom were here when human beings first arrived tens of thousands of years ago––and how people affected their environment and its animals, from the first migrating bands to the wildly destructive European colonizers.

Brando Crespi has devoted decades to sustainable development as co-founder and Executive Chair at Pro Natura International and Global Biochar. His holistic approach to sustainable development could be called regenerative––instead of telling poor and exploited people what they should do, it's about recognizing and cultivating local leadership, helping them form a community vision for their future, providing the assistance necessary to achieve that vision, and then getting out of the way.
Along the way, Crespi and his colleagues came across biochar, a substance made from burning bio waste (like sawdust and crop husks) and that has been used in the Amazon for millennia. As a soil amendment, biochar can bring dead soil back to life, improve crop yields, and decrease water use. It can also be used in industrial products and plastics. And its production can provide an energy source in communities looking to develop clean energy and regenerative agriculture.

John D. Liu started his career as a journalist and cameraman, covering politics, economics, and culture. In 1995, he began documenting the Loess Plateau in China, a massive landscape that had been destroyed by poor agriculture practices over the course of centuries. He watched and filmed as the landscape––and the people––came back to vibrant life over decades, through an intensive process that involved soil science, engineering, hydrological restoration, and the participation of local communities. The result was a living, lush, and sustainable ecosystem that produced more food with less land in agricultural production.

Gary Paul Nabhan, known by many as the "father of the local food movement," is a prolific author, scientist, and activist for a healthy and truly regenerative food system that respects the land and its plants and animals; the people grow food, process, and serve the food and their communities; and to all the rest of us who eat and want our food to nourish us. He's an ecumenical Franciscan brother whose service is devoted to food equity and justice.
W.K., Kellogg endowed chair for food and water security at the University of Arizona, he’s the author of many books; his latest is Jesus for Farmers and Fishers: Justice for All Those Marginalized in Our Food System. He’s an agrarian and ethnobotanist and is winner of numerous accolades, including a MacArthur fellowship and many literary, environmental, food, and arts awards.

Coley Burgess grew up on a conventional farm, then studied mathematics and electrical engineering...and he brought his scientific rigor and curiosity to a 20-acre pecan farm that he and his family bought in southern New Mexico. The ground was bare and turned to mud––and then cracked, dry earth––after he irrigated. But a series of happy accidents, including the purchase of a milk cow for his daughter's digestive health, led to his growing grass and cover crops and eventually letting go of herbicides, pesticides, and even chemical fertilizers.
