"Posthuman" signals a historical condition in which the coordinates of human existence on the planet are altered by profound technological, ecological, biopolitical, and spatial transfor-mations. Engendering new ways of being in the world, this condition challenges long-established definitions of the "human," and by extension, of the human environment. Interpret-ing design as a geographical agent deeply involved in the territorial engravings of contemporary urbanization, New Geographies 09 investigates the urban landscapes shaping the posthuman geographies of the early 21st century, fostering a wide-ranging debate about both the poten-tials and challenges for design to engage with the complex spatialities, more-than-human ecol-ogies, and diverse forms and habits of life in a post-anthropocentric world.
