This research work mainly focuses on study of various spheres and sections of ecocriticism. In the beginning, this research pertains to the emergence of the ecocritical theory after that it tries to understand the development of the theory with the pace of time. Although both the texts of Gita Mehta’s ‘A River Sutra’ and Arundhati Roy’s’ The God of Small Thing’s have been looked upon from various perspectives but comparative study from ecocritical perspective has its own significant. This comparative study not only focuses on the comparison between these texts but also emphasises on the interdisciplinary approach of the newly established discipline of comparative literature. It will attempt a thematic and structural analysis of both the writers, and their representation of the human- non human relation. Explicitly, both the authors are urging the readers to save our planet from total annihilation. For this they have adopted the technique of presenting non-human world in their writings. The detailed innumerable description of non-human world has been rendered wittingly. Key Word: Ecocriticism, Gita Mehta’s A River Sutra, Arundhati Roy’s The God of Small Things, interdisciplinary approach, ecological science, cultural production etc.
