The Transitional Territories lecture series explores the agency of design as a mode of investigation and reflexive transformation of the ever-changing interrelations between natural processes, societal practices, and (geo)political frameworks. The 2021-2021 edition introduces as an investigative lens the notion of accumulation broadly conceived: as a material process of anthropogenic transformation of the earth, but also as a process of – often unequal – social and ecological (re)organization. From the ecopolitics and hydropolitcs of accumulation, to its multiscalar metabolisms, the series aims to offer critical insights around the state and agency of the territorial project within the pressing context of the climate crisis and the associated social and ecological tensions.
