The term 'terraforming' usually refers to transforming the ecosystems of other planets or moons to make them capable of supporting Earth-like life, but the looming ecological consequences of what is called the Anthropocene suggest that in the decades to come, we will need to terraform Earth if it is to remain a viable host for Earth-like life. The Terraforming thus refers both to the terraforming that has taken place over the last century and millennia over the course of urbanization and to the terraforming that must now be planned and conducted as the planetary design initiative of the next century if true catastrophes are to be prevented. In this lecture, architect and Strelka's postgraduate program co-director Nicolay Boyadjiev will present an overview of the themes, conceptual provocations, and collaborative methodologies driving The Terraforming think tank at the Strelka Institute for Media Architecture and Design in Moscow.
