We were navigating along the Tapajós River when an agronomist, specialized in agroecology, pointed out to me a series of large trees on the horizon and commented; “These are chestnut trees planted by indigenous civilizations, possibly practiced 10,000 years ago.” I spent the rest of the trip, remodeling my cognitions about ecology, understanding that, in fact, from the ancestral times there was already a productive practice of mutualist coexistence between humans and the Amazon biome. A general concept that has already proven to be totally ineffective and obsolete, in the dialectic between; preserving without interfering or interfering without preserving, was shaped in a third way of understanding the possibility of human activity in symbiotic and regenerative coexistence with Nature.A decade later I learned that this thought has already been widely developed and is called; "Third Amazon Way" which main objective is to provide knowledge based on science, technology, innovation and strategic planning for the development of a “alive forest” economy with flowing rivers, a bioeconomy driven by the rich Amazonian biodiversity.
