As children’s literature increasingly engages with ecological concerns in the context of the climate crisis, ecocritical scholarship – including scholarship on visual narratives – has expanded over the past two decades. Much of this research has focused on interpretative analyses of representations of nature and the nonhuman in children’s literature. This dissertation builds on these approaches by adopting a post-representational perspective, examining entanglements of materiality, aesthetics, and paratextuality across five diverse visual narratives. Drawing on principles of material ecocriticism and intermediality, this dissertation emphasises the dynamic relations between culture and nature, mind and matter, and narrative and life in both the creation and reception of visual narratives. It argues that visual narratives have unique potential to challenge human exceptionalism, encouraging young readers to perceive humans as part of the material, naturalcultural world. Here, ‘nature’ is not a passive backdrop or victim of human dominance, but is mutually constitutive with the subject. This dissertation further contends that visual narratives are performative phenomena, presenting a material-discursive space in which creators, processes, books, and readers intraact. These intra-actions are revealed through an integrated analysis of both narrative representations and the paratextual and material elements of the book. The aesthetic and material affordances of the visual narrative are shown to have disruptive potential in how they might shape young readers’ perceptions of materiality, the nonhuman, and natureculture. By highlighting the power of complex, multimodal literature to develop and challenge understandings of nature and culture, this dissertation addresses a gap in current scholarship. The findings have implications not only for literary research but also for children’s literature publishing, particularly at a time when social and ecological challenges demand a reconceptualisation of nature, culture, and agency.
