This book highlights the representation of the interface between nature and culture in literary texts, and argues that bioregional exegesis of indigenous literatures sensitizes us to place-based cultural nuances, and can contribute to alleviating the eco-cultural apartheid of the modern era. Though the bioregional concept has been in vogue since 1970s, it has not been adequately adopted into the field of literary criticism. This book is a comprehensive study on the concept of the bioregion, and is distinctive in three ways. Firstly, it argues that the bioregional concept, hitherto used as a socio-political tool, can be theorized as an ecocritical tool to employ when reading literary works. Secondly, it provides a detailed analysis of the concept of bioregion, marking out its characteristic features. Thirdly, in choosing to deal with Aboriginal plays, the book again exhibits its distinctiveness, in demonstrating how ecocritical concepts, which hitherto have focused primarily on prose fictional works, can be extended to magnify the scope of plays and performances.
