This article examines how contemporary Kenyan prose fiction gives nature a voice, presence and capacity to act through anthropomorphic representation. Existing scholarship on Kenyan environmental literature has established the importance of ecological degradation, human–nature relationships and the politics of environmental exploitation, but less attention has been paid to anthropomorphism as an aesthetic means of presenting the nonhuman world as an agent rather than a passive backdrop to human experience. The article addresses this gap through a close reading of Henry Ole Kulet’s Vanishing Herds (2011), Ng’ang’a Mbugua’s the Angels of the Wild (2015), Ian McKenzie-Vincent’s Aziza and Bakari in the Climate of Change (2019), and Yvonne Adhiambo Owuor’s The Dragonfly Sea (2019). Guided by eco-aesthetic and postcolonial theories, and using a qualitative interpretive design based on close textual analysis, the study explores how landscapes, wildlife, forests, climate, seas and islands are endowed with voice, emotion, memory and agency. It argues that these representations do more than make ecological crisis vivid or emotionally accessible. They unsettle anthropocentric assumptions, expose the colonial and neo-colonial histories underlying environmental exploitation, and foreground more relational understandings of human–nonhuman coexistence. By bringing anthropomorphism to the center of analysis, the article extends Kenyan ecocritical scholarship by showing how literary representations of nature can function simultaneously as aesthetic expression, environmental witnessing and critique of unequal power relations.
