Which narratives can be considered eco-fiction? This talk explores what counts as eco-fiction in a moment when climate crisis seems to be permeating contemporary literature. Rather than treating eco-fiction as a narrowly defined genre, it is possible to identify recurring patterns in ecological discourse and consider how environmental concerns shape narrative forms more broadly. Drawing on my current research on a possible Subject of climate change, I propose to explore the concept of eco-fiction as a constructed set of narratives. Focusing on the evolving understanding of the term ecology and its presence in contemporary works, the talk examines how this concept operates as a key site of narrative construction. Ecological awareness of humanity’s impact on the Earth as a planet emerged from viewing it for the first time as a photographed artifact from space. Drawing on this perspective, the narration of ecology began to take on forms fundamentally different from those of the past. By understanding the emergence of ecology, and more broadly of global ecological awareness, as a paradigm shift within the Cold War context, this talk traces its conceptual and cultural implications and proposes a lineage that continues to shape its use in contemporary fiction.
