Sustainability is a notoriously fraught and slippery term, and yet one that is now well-established in mainstream usage across the contemporary world. While sustainability is widely discussed and theorised across range of disciplines, this book sets out to consider what innovations literary scholarship might bring to the sustainability debate, and indeed what sustainability as a concept might bring to literary scholarship. Putting forward a range of essays by leading and upcoming scholars, this book takes a non-prescriptive and critically reflective stance towards the problem of sustainability – a stance we describe as critical sustainability. Essays in this collection accordingly undertake a range of approaches, from applying tools of literary enquiry in order to interrogate sustainability’s paradoxes, to investigating the ways in which literature envisages sustainability or plays out its tropes. Overall, this book seeks to demonstrate how sustainability’s difficulties might open up a productive opportunity for interrogation and exploration of the kind that literary scholars and ecocritics are ideally placed to carry out.
