Fighting Destructive Dams: Lessons from the masters
Guest Article by Chicu Lokgariwar
“Everybody loves us Lepchas” said Tseten. He went on to explain that this affection was important to the Affected Citizens of Teesta and was a major reason that the group decided never to add violence[i] to their arsenal of techniques in their fight to save the Teesta.
The idea of non-violence being a strategic decision rather than a (purely) moral one intrigued me. I was at a meeting where several anti-dam activists from the North-Eastern states were present. As I listened to their stories, it was clear that these veterans had several lessons for those of us worried about the death of their rivers today. Each of the groups that had been compelled to fight for their rights had evolved strategies and developed tools to help them.
Sadly, the struggle against ‘development’ projects that adversely impact the lives and livelihoods of people, as well as cause irretrievable harm to the environment, continues in many places across the world. Rather than reinventing the wheel, it will be useful for young activist groups to have access to the lessons learnt by those who have preceded them.

North East India Rivers Review 2017: Agenda behind Brahmaputra & Barak Fesitvals won’t Help the Rivers

‘Banks of the Lohit will shine’: Glimpses of a free-flowing river

Assam, Arunachal and the North East India, West Bengal and Bangladesh are riverine entities in many ways. Ancient rivers flowing through this landscape have moulded not only the mountains and the silt-heavy banks, but cultural identity of the region itself. Rivers permeate through the literature, folklore, songs, poems, cuisine, even dressing… Bhupen Hazarika, the Bard of the Brahmaputra, likened the red ripples of the Assamese Gamcha (red and white stole) to the braided filigree of the Red River. When Guwahati University opened on the banks of Luit, Hazarika sang “Jilikabo Luiter Paar”..Banks of the Luit will Shine. Rivers stood for revolution as they stood for Love.. Jyoti Prasad Agarwal wrote “Luitar Parore Ami Deka Lora.. Moribole Bhoi Nai.” (“We are the youth from the banks of the Luit/ We are not afraid of death”). Older poets like Parvato Prasad Baruah wrote entire books full of poems of Luit and today modern poets in Assam like Jeeban Narah link their creative processes inextricably to rivers.
