Every monsoon, headlines scream about devastating landslides tearing through the Himalayas. We see the tragic loss, the ruined homes, the rising yearly toll, and naturally, we curse these destructive events.

But what if I told you these very landslides, these seemingly chaotic forces, are also fundamental architects of the Himalayan landscape?

What if, paradoxically, human life as we know it in these mountains owes its existence to them?

Let’s look beyond the immediate destruction and explore the complex dance between shifting slopes and human settlement.

The Challenge of Water Scarcity & Landslides as Saviours

Think of the Himalayas

Towering peaks, rushing rivers fed by glaciers, and intense monsoon rains. It seems water should be abundant.

Yet, for countless hillside communities, finding reliable water is a daily struggle.

Steep slopes mean rainwater rushes away almost instantly.

And those mighty glacial rivers?

These often carry too much silt, especially during summer melts, making them unsuitable for drinking without extensive treatment.

So, where does the precious, life-sustaining water come from?

Enter the landslide

When a slope gives way, it leaves behind a jumble of rock, soil, and debris.

This debris acts like a giant, natural sponge. Unlike the hard, non-porous rock surrounding it, this material can soak up rainwater.

But how does it hold that water?

As rain percolates down through the debris, it carries fine clay and silt particles – a process identified as piping of fines. These tiny particles eventually clog the gaps deeper down, often settling against larger boulders or changes in slope, forming a relatively impermeable layer – like lining the bottom of our sponge. This natural lining traps the water above it, creating what geologists call a perched aquifer – a localized, underground reservoir.”

Many traditional Himalayan springs and the water of the naulas or dharas that have quenched the thirst of villages for generations, emerge precisely from such ancient landslide deposits.

These are tangible proof of landslides playing the role of water providers.

Fertile Ground from Ancient Upheavals

Water is essential, but survival also needs food.

For millennia, agriculture and animal husbandry have been the backbone of Himalayan life.

But where do you find fertile soil on steep, rocky mountainsides?

Again, landslides play a surprising role.

Fresh landslide debris is just broken rock.

But over time – decades, centuries – nature gets to work. Rain, wind, temperature fluctuations, and crucially, microbes, start breaking down this debris. It weathers, decomposes, and gradually transforms into soil – a precious commodity in the mountains.

These ancient, stabilized landslide zones often form gentler slopes or natural terraces (‘fans‘ or ‘cones’ at the base of slopes) compared to the surrounding steep rock faces.

Look closely at many Himalayan villages

Their terraced fields, vibrant with crops like rice, wheat, millet, or vegetables, often cling to slopes formed by these old, stabilized landslide deposits.

People recognised these fertile pockets. They painstakingly terraced these slopes, a practice that not only allowed farming but also further stabilised the land by reducing overall slope and controlling surface runoff.

It was a partnership: the landslide provided the foundation, and human ingenuity cultivated it.

Landslides and Human Habitations 

So, landslides provided two key ingredients for life: reliable water sources and patches of fertile soil.

It’s no surprise then, that if you map human settlements across the Himalayas, you’ll find a striking pattern: most traditional villages are nestled near, or built upon, these stabilized, ancient landslide zones.

Nature, through these powerful geological events, essentially issued an invitation, creating pockets where life could take root and flourish.

Traditional Wisdom and Respect for Nature

Crucially, the people who first settled these areas understood the mountains‘ power.

They lived with the risk, not in denial of it. Their wisdom, born from generations of observation, prioritised safety, often over convenience.”

Despite both water sources and agricultural land being mostly located on middle and lower slopes of the valley, the traditional villages  were often strategically sited on stabler ridges or higher ground, above known slide paths, even if it meant a longer walk down to the water source or agricultural fields.

They accepted this inconvenience as the price of safety. They knew which slopes were talking and showing signs of instability and which were sleeping.

Their practices reflected this deep understanding.

Maintaining Jungle Guls

These weren’t just random ditches; Jungle Guls were meticulously constructed and maintained drainage channels, often stone lined to minimise seepage, and were sited upslope of instability prone habitations and were designed to safely guide excess monsoon water away from the vulnerable slope directly into the nearby gadhera or stream, preventing saturation or build up of pore water pressure – a key landslide trigger.

The people thus understood the underlying reasons of slope instability and could identify slopes susceptible to landslides.

Avoiding Field Bunding

While bunding helps retain water in flatter terraces, traditional wisdom often dictated not building high bunds on upper, distant slopes, understanding that trapping too much water high up could destabilize the entire hillside below.

Bunding was thus resorted to in agricultural terraces close to the house from which water could be drained during spells of heavy rainfall.

This further reinforces that the people understood the connection between the presence of water and slope instability.

Lightweight Construction

Traditional houses invariably utilised locally sourced timber, stone and slate. These were then assembled using traditional earthquake safe craftsmanship.

The resulting structures were thus lighter and more flexible than modern concrete buildings, imposing less load on the slopes.

Carrying Capacity

This traditional way of life inherently respected the carrying capacity of the land.

The amount of water available from the local dhara or naula, the extent of fertile land on the stabilised slope – these dictated how many families, how many livestock, a particular location could sustainably support.

When these natural limits were reached, communities often branched out, founding new settlements in other suitable locations rather than overburdening their original site.

It was a natural system of checks and balances.

The Modern Challenge

So, what changed?

The modern era brought development, population growth, new economic pressures, and crucially, often a disconnect from geological realities and traditional knowledge.

This delicate balance has been dangerously disrupted.

The Roadside Rush

Roads, vital for connectivity, often follow river valleys, cutting through the toes of slopes and sometimes reactivating old landslides.

With the passage of time most economic activities got concentrated along these roads.

People were left with no choice but to migrate downwards from their safer, higher villages seeking opportunities, often settling on land previously deemed suitable only for agriculture – the very landslide deposits we discussed – because it was convenient and close to the road.

Moreover, with growing environmental consciousness restrictions were imposed on access to traditional building material (stone, timber and slate) and all construction activity revolved round construction material transported from the plains (bricks, saand, cement and reinforcement bars). So apart from convenience construction close to road became cost effective.

Ignoring the Foundations

Construction boomed.

But then, with large-scale, organised and often state sponsored promotion of RCC construction, heavy, multi-story concrete structures were built on these geologically weak landslide deposits, often without proper foundation studies, exceeding the ground’s bearing capacity – its ability to hold the weight.

Water In, But No Way Out

As settlements grew denser, water demand increased. Water was thus often  pumped in from distant sources.

But what about the wastewater?

Proper drainage networks were often lacking.

Sewage and wastewater seeped into the ground, saturating the porous landslide debris from within.

This constant saturation weakened the material and accelerated a phenomenon called piping of fines – where percolating water gradually washes away the fine particles holding the debris together, creating underground voids and causing the ground surface to slowly sink or subside.

Joshimath

The tragic situation in Joshimath is a stark, heartbreaking example of these forces colliding – construction potentially on an old landslide deposit, increasing population load, evidence of ground subsidence likely linked to inadequate drainage and subsurface water issues.

It’s a warning sign flashing bright red.

Lessons Learned and the Way Forward

The rising toll from landslides isn’t just fate; it’s often the result of choices that ignore the fundamental nature of the Himalayas.

To prevent future crises like Joshimath, we need a fundamental shift.

Heed the Carrying Capacity

We must honestly assess and respect the natural limits of vulnerable areas.

This means stricter zoning, limiting population density, and saying NO to inappropriate development on fragile slopes.

Engineer for Drainage

Robust, well-maintained drainage systems – both for surface runoff and wastewater – are non-negotiable in hillside settlements, especially those on debris.

This is paramount to prevent internal saturation and erosion.

Build Appropriately

Promote and enforce codes for lighter, earthquake-resistant construction suited to the Himalayan geological context.

Discourage heavy structures on vulnerable ground.

Listen to Lost Wisdom

Actively integrate traditional knowledge about slope stability, water management, and safe building locations into modern planning and engineering practices.

Consult with local communities – they often hold invaluable, place-specific knowledge.

Invest in Science & Warning

Enhance geological surveys, slope stability monitoring, and invest in reliable, community-accessible early warning systems for landslides.

Conclusion: A Sustainable Coexistence

Landslides are not malicious monsters; they are a powerful, natural force that sculpts the Himalayas.

They created the very niches where human life took hold.

The devastation we witness today stems less from the landslides themselves, and more from our collective amnesia – forgetting the hard-won wisdom of coexistence, ignoring geological truths in the pursuit of unchecked development.

A truly sustainable future in the Himalayas requires rediscovering a respectful partnership with the mountains.

It means blending modern science and engineering with traditional ecological knowledge.

It means making conscious choices that prioritize long-term safety and environmental health over short-term convenience or profit.

Only then can we hope to continue living alongside these shifting slopes, not as victims, but as informed, resilient inhabitants.
