John Jeavons and Ecology Action are featured in the March ODE magazine. Read here "... I made the pilgrimage up from San Francisco to sit at the feet of John Jeavons, who has probably spent as much of his life thinking about building soil as anyone who has ever lived. Jeavons started his career in the 1960s as a systems analyst at Stanford University. When the spirit moved him to pursue agriculture as a vocation, he brought that kind of analytical thinking with him. These are the questions that drove him: How many calories does a person need to survive? What is the smallest plot of land needed to grow those calories for one person for one year? How much land do we need to feed all the people on the planet? Jeavons has devoted his career to answering these questions and spreading that information around the globe. A small but significant chunk of that learning can be found in his book How to Grow More Vegetables Than You Ever Thought Possible on Less Land Than You Can Imagine, first published in 1974, which has sold half a million copies and gone through multiple editions.
