Hills creak under climate crisis, construction

The landslide that struck a national highway in Himachal Pradesh’s Kinnaur district has brought back focus on the delicate ecology of the region, which has been weakened further by the human-induced climate crisis and unchecked construction of power projects, experts say.

These factors together raise the possibility of landslides and floods, which loom as a threat in addition to the seismological features that predispose the region to earthquakes, which can further trigger big landslides.

Manshi Asher of Himdhara Collective, an environment group based in Himachal, summarised these as three factors that made the region vulnerable to disasters: fragile ecology, climate change and unplanned development.

“Kinnaur, located in greater Himalayas, is inheritably fragile. Due to a lot of tectonic movement the region is highly sensitive seismically and geologically,” said Asher.

The climate crisis, she added, has aggravated the problem. “Global warming has resulted in a change in rainfall pattern. Areas like Kinnaur which used to get less rains, have been witnessing high rainfall now”.

“And the last and most vital issue is haphazard construction taking place in these mountains,” she said, citing large hydropower projects that have come up or are planned in Kinnaur, at present inhabitant mostly by mountain tribes. The tunnelling, excavation and blasting work being done to build these dams threatens an already fragile landscape, Asher added.

A study carried out in Kinnaur between 2012 and 2016 found that a push for hydropower projects in the name of clean energy brought rapid landuse changes that adversely impacting local terrestrial ecosystems and communities inhabiting them.

It found that of the area of forest land diverted to non-forest activities between 1980 and 2014, 90% was transferred for hydroelectric projects and transmis
