How villagers in Bhutan and India came together to resolve a water-sharing tussle

There are 56 rivers that flow down from the Himalayan kingdom of Bhutan to the eastern state of Assam in India to meet the Brahmaputra River. The hills of Bhutan are covered with lush forests, but on the Indian side of the border there are vast tracts of dry plains with occasional patches of severely denuded forests. Not very long ago the forests were contiguous across the borders but internal migration, poverty and increasing demand for fuelwood changed the landscape drastically on the Indian side of the border.

Due to climate change all the rivers flowing from Bhutan to India have changed their behaviour dramatically in the last decade – with long periods of dryness, shallow flow and then repeated flash floods, followed by massive amount of silt, sand, sediments, stones and boulders hurtling downstream across the border into India, constantly altering the river’s course. This has caused hardships and misery to people on both sides of border.

A large share of Bhutan’s revenue comes from hydropower projects, although it has been declining over the years, from 44.6% in 2001 to 20% in 2013. Most of these hydropower projects have been developed in cooperation with India. Bhutan currently has an installed hydropower capacity of 1,488 MW, although it hopes to increase this to 20,000 MW.

Downstream communities in Assam have regularly raised the alarm, attributing these changes to dam building upstream in Bhutan. They are worried that the plans to build more dams in Bhutan will lead to more flooding, erosion and more destruction than good. The Bhutanese government and their Indian dam consultants have dismissed these objections in the past, but the recent erratic weather patterns have upset all predictions and is now shaping the future flow of the river and Bhutan’s relationship with India.
