The Spiti valley is the only cold desert in India other than Leh in Jammu and Kashmir.
In a missive to National Commission of Scheduled Tribes (NCST) vice president Ravi Thakur last month, the Shams Sangharsh Samiti said: “Very sadly, the elected governments at the centre and the state have proposed to construct a series of dams across the Spiti river in Sham valley, which is bound to be a recipe for disaster.”
The letter, also addressed to the Prime Minister's Office and the ministry of environment and forests, said last year's calamity in Uttarakhand was predicted by experts mainly due to unplanned dam construction that upset the ecological cycle and hill slope stability.
In 2012, residents of Lahaul Valley, some 122 km north of the picturesque Manali tourist resort, knocked on the doors of the union environment and forests ministry protesting against the upcoming hydropower projects on the Chenab river basin.
They said the projects not only threaten to displace them but will also affect the local ecology.
