To understand the development of the post-World War permanent agriculture movement and the movements that followed, we need to follow the trajectory of the movement of the field of ecology, and we cannot trace this evolution without talking about the Odum brothers. Eugene and Howard T. Odum were the sons of sociologist Howard Washington Odum & Anna Louise Kranz and would go on to change the trajectory of agroecology, for better or worse.

In 1954, both were hired by the Atomic Energy Commission to study a coral reef at the Eniwetok Atoll atomic test bomb site.3 Just the year before, Eugene had published the first edition of Fundamentals of Ecology, the first textbook focused on the concept of the ‘ecosystem’. As they had refined their beliefs on ecology and systems thinking (while Eugene had been the primary author in the book, Howard T had contributed chapters to it), their time working at this test bomb site provided the foundation for both brothers and their belief around ecosystem energy. The coral reefs were described by the brothers as a steady-state system; it was their assessment that the coral reef system used most of the energy it consumed through photosynthesis to regulate the system. It would be the example that the brothers would point to of what a mature ecosystem looked like— self-regulating, self-maintaining, and a steady-state system. Both brothers would go on to study different ecosystems and each provided new data that the condition of stability was characteristic of all mature ecosystems.
