This paper undertakes a sustained ecocritical examination of Kiran Desai's fiction, with particular attention to her debut novel Hullabaloo in the Guava Orchard (1998) and her Booker Prize-winning The Inheritance of Loss (2006). Drawing upon the theoretical frameworks of ecocriticism, postcolonial ecology, and environmental humanities, the study investigates how Desai employs landscape, geography, and ecological degradation as literary devices that mirror and intensify the psychological, cultural, and political fragmentation of her characters. The central argument of the paper is that in Desai's fictional world, the erosion of the natural environment is inseparable from the erosion of human identity, community, and cultural memory. Through close textual analysis, the paper explores how the Himalayan foothills of Kalimpong and the withering guava orchard of Shahkot become symbolic territories where ecological loss resonates with existential crisis. The study further situates Desai's work within the broader discourses of climate anxiety, postcolonial guilt, and the enduring legacies of imperial exploitation that continue to shape both environments and human subjectivities across the Indian subcontinent. The paper concludes that Desai's fiction makes a significant and underappreciated contribution to Indian English literature's engagement with environmental ethics and ecological consciousness.
