A nippy November morning saw me driving along a mountain road in Tripuradevi village in India’s Pithoragarh district, Uttarakhand, with the warm sun peeping through the tall pines.

I was there to buy hand-woven organically dyed silks and cottons created by Avani, a community organisation employing local craftsmen and providing them with a steady source of income, alongside that from the surplus crops and produce they sell. But what caught my eye were heaps of pine needles drying in the sun. A man was feeding the dried pine needles into a large gently humming metal cylinder attached to more chambers and motor.

The set up, I was told, was a power plant to generate electricity from pine needles.

Uttarakhand, also known as Dev Bhoomi or “land of gods” for its many pilgrimage centres, is an Indian state in the western arm of the Himalayas, bordering Tibet to north and Nepal to east. The state’s unique ecosystem is made up of snow-clad mountains, rivers, lakes and diverse flora and fauna.

A large part of this landscape is the chir pine forest, large plantations of which were introduced by British colonists and continued by later governments for commercial timber and resin. But the chir pine’s dominance in the landscape – it covers nearly 400,000 hectares (1,540 square miles) of Uttarakhand – has contributed to other problems. These pines shed their needles onto the forest floor, littering it in what is essentially delicate shreds of dry, high-energy kindling. Read more from BBC.
