In 1996, out of every hundred students who sat for the Class 10 board exams in Ladakh, roughly five passed. Read that again. Ninety-five children were being told, year after year, that the system had no room for them.

That number had been stuck there for as long as anyone could remember — a quiet, ugly statistic buried in a cold desert most of India never thinks about.

One man refused to accept it. His name is Sonam Wangchuk, and if you know him only from 3 Idiots or the 2026 Delhi protests, you’ve seen maybe a tenth of the story.

A Boy by the Indus

Sonam Wangchuk was born on 1 September 1966 in Uleytokpo, a small village near Alchi in Leh district. The remote region had limited road access, and winters could cut villages off for months.

Until he was nine, he didn’t attend school in any real sense. His mother taught him to read and write at home, in Ladakhi — the only language the family spoke.

When he finally walked into a classroom, he hit a wall. The lessons came in a language he barely understood, and suddenly a sharp, curious boy looked slow. He has spent his entire life trying to make sure no other child feels that.

That personal bruise is the seed of everything. SECMOL, the ice stupas, the marches, the fasts — all of it traces back to a nine-year-old who couldn’t follow what his teacher was saying.

The Engineer Who Came Home

He went on to study mechanical engineering at the Regional Engineering College in Srinagar, which today is NIT Srinagar. A degree like that, in the 1980s, was a ticket out of the mountains.

He took the ticket — and used it to go straight back. Instead of a city job and a steady salary, he returned to Ladakh with a group of like-minded friends.

In 1988, they started SECMOL, the Students’ Educational and Cultural Movement of Ladakh. It began as a small, idealistic outfit run by young people who believed Ladakh’s students deserved better than rote learning in a foreign language.

Operation New Hope: The Numbers Nobody Believed

Here’s where the story stops being about one man and starts being about a system.

In 1994, SECMOL pulled off something unusual — a genuine three-way partnership. The government, the village education committees, and SECMOL sat down together to fix government schools from the inside.

They rewrote textbooks in Ladakhi. They trained teachers to teach children instead of syllabi.

Villages formed education committees and took charge of their own schools. The programme got a hopeful name: Operation New Hope.

The results arrived faster than many expected. Ladakh’s Class 10 pass rate, recorded at around 5% in 1996, climbed to about 50% by 2005 and reached approximately 75% by 2015.

Think about what that means. In a single generation, a region went from failing almost all of its children to passing most of them. You won’t find many education turnarounds like it anywhere in India.

3 Idiots Connection: A Disputed Claim

In 2009, 3 Idiots, a film about engineering students challenging rote learning, became a national phenomenon. Its fictional innovator, Phunsukh Wangdu, ran a school in Ladakh, prompting many viewers and media reports to compare the character with Wangchuk.

That connection is disputed. In July 2026, actor Aamir Khan said that neither he nor writers Rajkumar Hirani and Abhijat Joshi knew about Wangchuk while making the film, and he rejected the claim that the character was based on him. Wangchuk has likewise said that the film was not his biopic, although he has not ruled out the possibility that some elements may have been indirectly influenced by his work. He has also said that a film crew visited SECMOL before the film’s release without disclosing the project.

Wangchuk has consistently resisted being labelled “the real Phunsukh Wangdu.” He has stressed that the film is fiction and that his work at SECMOL should be judged on its own record.

Ice Under a Bridge

Now the idea he’s most famous for — and it started, of all places, under a bridge.

In May, during a relatively warm part of the Ladakhi year, Wangchuk noticed a patch of ice surviving under a bridge near the school. The observation showed him that solar exposure, along with air temperature and wind, plays an important role in how quickly ice melts.

That tiny observation became the Ice Stupa. Ladakh’s problem was never a lack of water in winter — it was that the water arrived at the wrong time. Natural glaciers melt in June and July, long after farmers have sown their fields in April and May.

Wangchuk’s fix was almost embarrassingly simple. In the winter of 2013, he and his students piped stream water downhill using nothing but gravity. The water shot out of the pipe as a fine spray, froze in the sub-zero air, and piled up into a cone — the shape that exposes the least surface to the sun.

That first two-storey prototype was about 6 metres (20 feet) tall and held roughly 1,50,000 litres. The next winter, with about ₹75 lakh raised through donations, the team built a larger one that released roughly 20 lakh litres of meltwater well into June.

The economics were just as striking. Wangchuk told Scroll.in in 2015 that the capital cost came to about ₹0.025 per litre. His line became famous: “Water is free ever after.”

The inspiration wasn’t entirely his, and he says so openly. An older Ladakhi engineer named Chewang Norphel had been building flat artificial glaciers at high altitude for years. Wangchuk’s contribution was to bring the idea down to the villages — and to shape the ice so it survived the sun.

In 2016, the Rolex Award for Enterprise recognised the Ice Stupa project with 100,000 Swiss francs in prize funding. The award supported the wider Ice Stupa programme and helped provide seed funding for HIAL, Wangchuk’s proposed alternative university for mountain communities.

Natural Glacier vs Ice Stupa

Aspect	Natural glacier	Ice stupa
Where it sits	Usually in high mountain zones	Can be built closer to villages where a suitable water source and elevation gradient exist
When the water comes	Seasonal melt varies by glacier, altitude and weather	Designed to release water during the spring planting period
Energy used	Natural process	Gravity-fed pipes can operate without pumps or electricity
Time to form	Develops over long geological periods	Built during one winter
Cost per litre	—	About ₹0.025 in a 2015 project estimate
Maintenance	Natural process	Seasonal rebuilding, monitoring and occasional pipe or nozzle maintenance

The Awards That Chased the Work

The honours have a habit of arriving years after the work is done — which is how you know the work mattered.

In 2016 came the Rolex Award for Enterprise, for the Ice Stupa. Then, in 2018, the Ramon Magsaysay Award — often called Asia’s Nobel — for his decades of quiet reform in Ladakh’s classrooms.

What the award committees saw was a rare combination. Here was an engineer who built things, a teacher who started movements, and a reformer who actually stuck around to see the results. That mix is uncommon, and it’s why he gets invited to universities, climate summits, and government committees that rarely agree on anything else.

A University That Runs on Sunlight

SECMOL’s campus is famous for running on solar power, passive heating, and student labour. Wangchuk wanted to scale that philosophy into a full university.

The result is HIAL, the Himalayan Institute of Alternatives, Ladakh. The idea is a university built for mountain life — one that teaches students to solve mountain problems with mountain resources, from solar energy to sustainable tourism.

In 2018, HIAL received an allotment of roughly 135 acres in Phyang village for a proposed 40-year lease. In August 2025, the Ladakh administration cancelled the allotment, saying that a formal lease had never been executed and that a legally recognised university had not been established on the land.

Wangchuk and the Leh Apex Body called the cancellation a witch-hunt — one more sign, they argued, that New Delhi was tightening the screws on Ladakh’s campaigners. The timing was hard to ignore. It came weeks before the protests of September 2025 turned deadly.

Ladakh Finds Its Voice

To understand Wangchuk’s later years, you need one date: 5 August 2019.

That’s when Article 370 was revoked and Jammu and Kashmir was split into two Union Territories. Ladakh became a UT with no legislature of its own — and for many Ladakhis, that felt less like progress and more like a loss of control over their land, jobs, and culture.

The Leh Apex Body (LAB) and the Kargil Democratic Alliance (KDA) came together around four demands: statehood for Ladakh, inclusion under the Sixth Schedule, a Lok Sabha seat each for Leh and Kargil, and safeguards for local jobs and land.

Wangchuk became the movement’s most recognisable face. In March 2024, he sat through a 21-day “Climate Fast” in Leh, from 6 to 26 March, in sub-zero conditions. It wasn’t about himself — it was about forcing Delhi to the table.

The Long Walk to Delhi

Later that year, he decided to walk. The “Delhi Chalo Padyatra” began on 1 September 2024 — a journey of nearly 1,000 kilometres from Leh to the national capital, initially involving more than 100 supporters, including elderly Ladakhis and army veterans.

They reached Delhi’s edge in early October. On 1 October, police detained Wangchuk and several others at the Singhu border under prohibitory orders. He was released about 36 hours later, on Gandhi Jayanti.

After presenting a memorandum to the Home Ministry, he told reporters:

“The Home Ministry has assured us that our wish for a meeting with either the Prime Minister, Home Minister, or President will be granted in the coming days. We end our march in the trust that the government will honour its assurance.”

2025: Four Deaths, One Arrest

The year 2025 is where Wangchuk’s story stops being easy to summarise.

In September, he and the Leh Apex Body announced a 35-day fast. He told reporters in Leh:

“Despite repeated assurances, there have been no talks for nearly two months. Just when discussions were about to reach the stage of addressing our core demands, the government stopped calling meetings.”

Then it all unravelled. On 24 September 2025, protests in Leh turned violent.

Two elderly hunger strikers had collapsed and been hospitalised, and a crowd — around 2,000 people by some accounts — broke away and set fire to government buildings and BJP offices.

Police opened fire. Four people died, aged between 19 and 46, and dozens more were injured.

Two days later, on 26 September, Wangchuk was detained under the National Security Act — a law that allows detention without formal charges. He was flown out of Leh and locked up in Jodhpur Central Jail, roughly 1,000 kilometres from home.

The government blamed his “provocative statements” for the violence. His supporters called the arrest a punishment for peaceful protest. His wife, Gitanjali Angmo, filed a habeas corpus petition in the Supreme Court, and on 6 October the court questioned why the grounds for detention hadn’t been shared with the family.

From jail, Wangchuk’s message stayed characteristically calm:

“I am doing well, both physically and mentally… unless there is an independent judicial inquiry into the killing of the four people during the September 24 violence, I am prepared to stay in jail.”

Authorities also investigated his organisations’ foreign funding, and SECMOL’s licence to receive overseas money was reportedly cancelled. His family denied any wrongdoing, calling the allegations politically motivated.

The detention ended on 14 March 2026, when the Ministry of Home Affairs revoked the NSA order “with immediate effect.” He had spent close to six months inside.

2026: Jantar Mantar and the CJP

Most biographies end around here. His kept going.

By mid-2026, India’s young people had a movement of their own. After the NEET-UG 2026 exam was cancelled over a paper leak, a protest group called the Cockroach Janta Party took over Jantar Mantar in Delhi. The name comes from a judge’s remark comparing unemployed youth to cockroaches — the students reclaimed it as a badge.

The CJP’s demand was blunt: the resignation of Union Education Minister Dharmendra Pradhan. On 28 June 2026, Wangchuk joined their fast. He was 59 years old and had been out of jail for barely three months.

Asked why he’d thrown himself into a student protest, he told The New York Times:

“Victims never raise their own voice. This time, for a change, young people were doing that. How could I not support them?”

He fasted on salt water for weeks. By 15 July, his weight had dropped to 57.15 kg. On 18 July, police in civilian clothes carried him from the protest site to a hospital, citing a court order to intervene if his health deteriorated.

Wangchuk ended his fast after 26 days when Union Ministers J.P. Nadda and Dr. Jitendra Singh met him in hospital. The government gave written assurances concerning peaceful protesters, consideration of compensation for affected families, and discussion of examination reforms in Parliament. The CJP welcomed the end of his fast but said its own protest would continue.

10 Things Most People Don’t Know

He didn’t speak a word of the school language until he was nine — and he failed to understand his own lessons for years.
The Ice Stupa idea was born from ice he spotted under a bridge, still frozen in the May heat.
The first ice stupa prototype was about 6 metres (20 feet) tall. Students built it with him using gravity-fed pipes and no electricity.
In 2015, Wangchuk estimated the Ice Stupa project’s infrastructure cost at about ₹0.025 per litre of stored water.
He has spent years telling people he is not Phunsukh Wangdu. The widely reported connection between him and the fictional character remains disputed.
SECMOL’s campus is run by its students — they vote on rules, cook, clean, and take turns running the place.
The school specifically admits students who failed Class 10. The system gave up on them; SECMOL didn’t.
His inspiration for artificial glaciers was Chewang Norphel, the veteran Ladakhi engineer known as the “Ice Man of India”. Born in 1935, Norphel built his first artificial glacier decades before the first ice stupa.
“Wangchuk” means “powerful” in Tibetan.
During the 2026 fast, he dropped to 57.15 kg — and still refused solid food until the government’s ministers came to the table.

Did You Know?

A President praised the turnaround. In 2005, A.P.J. Abdul Kalam visited Leh to launch the Ladakh Model of Sarva Shiksha Abhiyan. He pointed to Operation New Hope’s numbers — 5% to 50% — as proof of what local ownership can do.
The first ice stupa was a science experiment with students. The low-energy, gravity-fed prototype demonstrated a new way to store winter water in cold deserts.
The CJP’s name is borrowed from an insult. A judge called unemployed young Indians “cockroaches,” and the students turned the slur into their movement’s identity.
The 2026 fast wasn’t his first. He did a 21-day climate fast in 2024, a three-day fast in Kargil, and a 35-day fast announcement in 2025 — all for Ladakh’s constitutional demands.
Ice stupas have travelled. Versions of the design have been tried in other mountain regions, including a pilot project in the Swiss Alps.

What We Can Learn

Strip away the politics and the protests, and a few lessons stay standing.

Observation beats invention. The ice stupa didn’t come from a lab. It came from watching ice melt under a bridge and asking the right question.
Systems change when locals lead. Operation New Hope worked because villagers, teachers, and the government built it together. Outsiders can help, but they can’t own it.
Numbers tell the truth. 5% to 75%. Four deaths. 26 days. When Wangchuk makes a point, he tends to bring receipts.
Fame is a tool, not a goal. The public association with 3 Idiots brought wider attention to his work, and he repeatedly redirected that attention towards Ladakh.
And a harder one — conviction has a cost. Whatever you think of his politics, spending 170 days in preventive detention and undertaking a 26-day fast demonstrate a high personal commitment to his causes. That commitment can be acknowledged even by people who disagree with his methods.

He began fasting at Jantar Mantar on 28 June 2026 in support of the CJP-led movement over the NEET-UG paper leak and examination accountability. He ended the fast after 26 days following written government assurances and meetings with Union ministers; the CJP said its wider protest would continue.

10. What does he want for Ladakh?

Statehood, Sixth Schedule status, separate Lok Sabha seats for Leh and Kargil, and legal protection for Ladakhi land, jobs, and culture.

A Closing Thought

There are now two public images of Sonam Wangchuk, and the media often struggles to hold both in the same frame.

One is the engineer and education reformer associated with a rise in Ladakh’s Class 10 pass rate from about 5% in 1996 to roughly 75% by 2015, and with an inventive response to seasonal water scarcity. That legacy is rooted in classrooms and Ice Stupas rather than party politics.

The other is the activist — detained under the NSA, accused of stoking violence, fasting at Jantar Mantar behind a student movement he didn’t start. That man divides opinion, and honestly, he’d probably be suspicious of anyone who liked him too easily.

You can disagree with the protests and still admire the ice stupas. You can question the detention and still wish the movement had never turned violent. The two truths sit side by side, and pretending otherwise flattens a complicated, stubborn, genuinely interesting life.

What nobody can take from Sonam Wangchuk is the consistency of his method. For more than three decades he has repeatedly tried to identify a problem, develop a practical response, and stay engaged with the outcome.

Whether that makes him a reformer or a troublemaker depends on where you’re standing. In Ladakh, a lot of people know exactly which one he is.
