The Dangerous Cost of Dams, Tunnels, and Four-Lane Roads in Himachal Pradesh
Introduction
Himachal Pradesh, often called Devbhoomi, is home to the sacred Himalayas, revered rivers, and deeply spiritual communities. However, in recent times, this divine landscape has been marred by increasingly severe natural disasters, including landslides, flash floods, falling peaks, and tragic deaths. The districts of Mandi, Kullu, and Kinnaur have become the face of this ecological crisis.
Behind these tragedies lies a troubling truth—aggressive and unscientific development in the form of dam projects, tunnel construction, and four-lane highways. What we call progress is often a brutal assault on the Himalayas' natural balance. When we alter the course of rivers, bore tunnels through fragile slopes, and strip forests from steep hillsides, the consequences are not just environmental—they're human.
1. The Fragile Backbone of the Himalayas
The Himalayas are geologically young and unstable, unlike ancient rock formations like the Deccan plateau. Continuous tectonic movement keeps these mountains vulnerable to cracking, sliding, and collapsing.
- Boring tunnels through mountains
- Dynamiting slopes for roads
- Building massive reservoirs
These activities disturb natural equilibrium, leading to frequent landslides, collapsing villages, and deadly flash floods. According to a 2024 Geological Survey of India report, over 40% of Himachal Pradesh is a “high landslide risk” zone—yet construction continues unabated.
2. Dams: Blocking the Flow of Life
Hydropower projects like Karcham Wangtoo, Nathpa Jhakri, and Sawra Kuddu have altered river ecosystems.
Environmental Consequences:
- Disrupted flow kills aquatic life and harms irrigation.
- Reservoir seepage weakens slopes, increasing landslide risk.
- Reservoir-induced seismicity (RIS) can cause tremors and rockfall.
Human Tragedy:
- Kinnaur: Villages like Urni and Nisang suffered home collapses due to dam tunnels.
- Joshimath (Uttarakhand): 800+ homes cracked after years of dam tunneling.
The diversion of rivers through long tunnels changes the identity, ecology, and economy of valleys, often permanently.
3. Tunnels: Wounds in the Mountain
The Unseen Effects:
- Punctured groundwater veins—springs vanish.
- Destabilized slopes during rains.
- Debris clogging rivers and valleys.
In Rampur, 100+ homes cracked during tunnel boring. In Aut (Kullu), debris from tunnel sites has caused repeated road collapse.
The Silkyara Tunnel collapse (2023) in Uttarakhand trapped workers for days, exposing the lack of safety protocols.
4. Roads with Four Lanes: Accelerating Toward Collapse
Projects like the Char Dham highway and Shimla-Parwanoo expansion require deep hill cutting.
Why they are dangerous:
- Steep cuts destabilize hillsides.
- Blasted debris not properly disposed.
- Poor drainage weakens road structures.
Real-life examples:
- Mandi (2025): Roads collapsed, cutting off emergency services.
- Solan (2022): Road widening triggered a landslide.
- Kullu (2024–25): Widening of Bhuntar–Manikaran road led to repeated landslides.
5. Mandi District: A Tragic Humanitarian Event in 2025
Mandi faced one of its worst natural disasters:
- 50+ deaths due to floods and landslides.
- Roads and villages in Seraj, Karsog, Sundernagar cut off.
- Flash floods in Uhl River swept away homes.
Structures built near seasonal nalas were decimated. Helicopters couldn’t land for rescue; help arrived too late. This was not merely a natural disaster, but the result of unchecked, unscientific planning.
6. The Forgotten Rivers: Nalas and Bourns
Seasonal nalas are now wrongly seen as safe. But during cloudbursts:
- They turn into raging torrents.
- Homes and shops on their beds get washed away.
Despite warnings from elders, modern builders continue to block these ancient water pathways—damaging both ecosystem and heritage.
7. GD Agarwal: The River Warrior
GD Agarwal, also known as Swami Gyan Swaroop Sanand, was a saint-scientist who gave his life for the Ganga.
His Legacy:
- Former IIT professor and first Member Secretary of CPCB.
- Fought damming of Bhagirathi River in Uttarakhand.
- Went on hunger strikes to demand Ganga’s protection.
He passed away in 2018 after a 111-day fast, demanding:
- Free-flowing Ganga
- Ban on upper-Himalayan dams
- Spiritual and ecological respect for rivers
His voice was silenced—but his warning remains loud today.
8. What Needs to Change
✅ Pause and Rethink:
- Moratorium on new tunnels and dams in fragile zones.
- Mandatory cumulative environmental impact assessments.
✅ Empower Local Wisdom:
- Consult Dev Sanskriti leaders and locals in planning.
- Respect rivers, forests, and sacred spaces.
✅ Reform Road Projects:
- Use bio-engineering and green corridors.
- Ensure slope stability and proper drainage.
✅ Transparency and Accountability:
- Make landslide and disaster risk maps public.
- Create independent hill-state environmental tribunals.
Conclusion: Pay Attention Now, Not Later
Nature does not speak in words. It warns us through landslides, flash floods, and lost lives.
We must choose between blind growth and sustainable survival. Let us honor the legacy of people like GD Agarwal by protecting the soul of our mountains—our rivers, forests, and people.
