If regenerative agriculture is about rebuilding the foundations of our food system, then soil is where that story starts.
Geologist and author David Montgomery [https://www.dig2grow.com/] has spent decades tracing how the health of our soil shapes everything else: the nutrition in our food, the resilience of our farms, and the long-term fate of entire civilizations. What he shows is both sobering and energizing. We have degraded our soils at an astonishing pace, yet we now understand enough about how they actually work to turn the tide.
In this conversation, David helps us zoom out. He connects the collapse of ancient societies to the vulnerabilities we see in modern industrial agriculture, and he lays out what farmers around the world are doing to rebuild soil faster than it erodes. If regeneration is the goal, soil biology is the map.
In this episode, we get into: • How soil degradation has shaped the rise and fall of societies • The real consequences of erosion, tillage, and synthetic nitrogen • Why soil microbes are central to nutrient density and farm resilience • What regenerative farmers are proving about soil recovery timelines • Three core principles that can rebuild fertility at scale • Why technology must complement, not replace, ecological understanding • The policies and incentives needed to make soil health the baseline, not the exception

This week we go to Germany to learn about a cooperative called Kulturland who has been working on solving the farming land access problem for over a decade. Kulturland raises money from everyday people and uses that capital to buy farms, take them off the speculative market, and provides farmers with a secure lease. In return, the farmer commits to farming organically and keeping the farm open to the community.
If we're serious about building a better food system, we have to start with land.
We often talk about how the food system is broken, but what would it look like to build one that is better?
Hi everyone - Emma here. We're deep in prep for our new miniseries on Agrarian Futures where we will be exploring the potential for a better food system rooted in cooperative principles.
Our guest today Will Potter's new book, Little Red Barns [https://www.willpotter.com/littleredbarns], started as a tale about censorship in journalism around industrial agriculture, but became something much bigger: a 10 year investigation look at how factory farming, an ages old mythos of family farms, and the rise of authoritarian politics have all worked in tandem to produce social, economic, and ecological disaster.
