In this project, which has been my most extensive yet, I travelled along the river Bharthapuzha that runs through the length of Kerala, documenting the environmental condition of the river and the lives and occupations of people who live by it. In this process, I interacted and engaged with many people who have been closely related to the river, through personal histories, and some of them, through conservation efforts. In this process, I learnt of how environmental conservation is inextricably linked to social justice. And in a deeply hierarchical society like Kerala, conservation and caste cannot be addressed separately. These are complex questions, which I perceive and have attempted to understand. However, how does one address the difficult relationships between society, economy and environment in our conservation efforts? I have tried to use the medium of film as a tool for research. Through this medium I have tried to understand how the changes in society, culture and economy of the riverside population may have contributed to the degradation of the river.
