From Hazard to Heritage: Landslides Risks, Geoheritage Potential, and Geotourism Opportunities along NH-44 corridor, Jammu and Kashmir, India

The Himalayas are often called the youngest mountain range on Earth, a place where the ground is still rising, shifting, and cracking under immense pressure. In these high, steep valleys, the line between a beautiful landscape and a dangerous one is often razor-thin. When heavy rains soak the soil or the earth trembles, slopes that look solid can suddenly give way, sending rocks and mud crashing down. This is a landslide, a natural event that has shaped the mountains for millions of years but poses a constant threat to the people living and traveling through them. For decades, scientists and engineers have studied these slopes to figure out how to keep roads open and people safe. But there is another way to look at these dangerous places. Instead of seeing them only as sites of destruction, researchers are beginning to see them as open-air museums. The very rocks that slide down the hill tell a story of how the mountains were built, preserving fossils, ancient volcanic flows, and the scars of massive tectonic collisions. Understanding this dual nature—where danger and history coexist—is the key to living safely and wisely in these rugged regions.

In the western Himalayas, a single road connects the Kashmir Valley to the rest of India. This is National Highway 44, a vital artery that carries people, goods, and essential supplies through some of the most difficult terrain on the planet. Specifically, the stretch between Ramban and Banihal is notorious for its instability. For years, this corridor has been a zone of disruption, where traffic is frequently blocked by falling rocks and sliding earth, causing delays and sometimes tragedy. A new study by researchers from India has taken a fresh look at this stretch of road. They did not just map where the landslides happen; they also mapped the geological treasures hidden within the same slopes. By combining advanced mapping techniques with a deep appreciation for the region's natural history, the team has shown that this dangerous corridor is also a unique window into the Earth's past, offering a rare opportunity to turn a hazard zone into a place of learning and discovery.

The researchers began by creating a detailed map of the landslide risks along this fifty-kilometer section of the highway. They gathered information from satellite images, field surveys, and historical records to identify every known slide, rockfall, and debris flow. In total, they cataloged 117 separate incidents. Their analysis revealed a clear pattern: more than eighty percent of these failures were not random accidents. Instead, they were tightly linked to the underlying geology. The road cuts through specific zones where the rock has been crushed and shifted by massive tectonic forces, creating weak planes that slide easily. When heavy monsoon rains soak these weak layers, or when the road itself steepens the slope, the ground gives way. The study found that nearly forty percent of the corridor is at high risk of landslides, with another forty percent at moderate risk. These dangerous areas are concentrated in specific spots like Digdole and Nachlana, where the road hugs steep, fractured cliffs. The remaining twenty percent of the route sits on more stable ground, such as gentle valley floors.

While the risk is real, the same geological features that cause the slides also hold immense scientific value. The road cuts expose a continuous slice of the Earth's history, stretching from ancient rocks formed over a billion years ago to volcanic layers from much more recent times. Along the highway, one can see layers of rock that contain fossils of ancient sea creatures, evidence that this high mountain region was once underwater. There are also massive sheets of volcanic rock and huge cracks in the earth where tectonic plates have pushed against each other. The researchers argue that this corridor is a natural archive, a place where the story of the Himalayas is written in stone. Every landslide scar and every exposed rock face tells a part of the story of how the mountains rose and how the landscape has changed over millions of years.

The study suggests that we can change how we view this place. Instead of seeing it only as a problem to be solved, we can see it as a resource to be understood. The authors propose turning parts of the highway into a living classroom. They imagine safe viewing areas where travelers could stop to see the exposed rock layers, read signs explaining the geology, and learn about why landslides happen. They suggest building a small museum in the nearby towns to teach visitors about the forces that shape the mountains and how communities can prepare for disasters. This approach would not only protect the geological features but also help local people understand the risks they face, turning fear into knowledge. By training local guides to explain the landscape, the community could also benefit from a new form of tourism that respects the land and its history.

The road itself has already seen major improvements to handle these challenges. Engineers have built long tunnels that bypass the most dangerous sections of the mountain, allowing traffic to flow safely underneath the unstable slopes. These tunnels, including the Jawahar Tunnel and the newer Chenani-Nashri Tunnel, are feats of modern engineering that cut through the very rock layers the scientists are studying. They represent a balance between the need for safe travel and the reality of the terrain. The researchers note that while these structures are essential, they do not eliminate the need to understand the landscape. The tunnels pass through the same complex geology, and the surrounding slopes still require careful monitoring. The goal is to combine these engineering solutions with a deeper respect for the natural world, ensuring that development does not come at the cost of safety or heritage.

Ultimately, the work along the Ramban-Banihal corridor offers a new way forward for mountain regions around the world. It shows that a place can be both a hazard and a heritage site, and that these two identities do not have to be in conflict. By mapping the risks and the resources together, the researchers have provided a blueprint for managing these fragile landscapes. They show that with careful planning, education, and community involvement, it is possible to build roads that are safe, preserve the geological history of the mountains, and help people live in harmony with the dynamic earth beneath their feet. The corridor remains a place of risk, but it is also becoming a place of learning, where the story of the Himalayas is told not just in books, but in the very ground beneath our feet.
