Thirty years ago, a group of students from Delhi University went on a long walking tour of the Narmada valley. The journey was arduous, and it was not undertaken for pleasure. The students wished to study, at first-hand, “the possible environmental impact of the massive hydroelectric and irrigation complex planned for the Valley, and to see and document the existing natural and cultural heritage of the [Narmada] river”. They wrote a report based on their trip, versions of which were published in the The Ecologist of London and the Economic and Political Weekly of Mumbai. Rich, fact-filled, and written in understated prose, these documents are of considerable historical interest. For it was by reading the article in the EPW that Medha Patkar, then a social activist in the city of Mumbai, decided to shift to the Narmada valley to work there.
