The last weekend of the Introduction to Agroecology course taught by the Emmanuel Center, had the participation of the National Director of Agroecology of Argentina, Eng. agr. Eduardo Cerdá. Its exhibition took place at the Daniel Armand Ugon High School in the city of Colonia Valdense, within the framework of the 135 years of said institution. The talk by the Argentine agronomist, with extensive experience in the field of alternative agricultural practices, was about the “13 basic principles of Agroecology.” Below we share the video of the presentation, which is part of the “Open Talks” playlist on our YouTube channel.
