Who is Sonam Wangchuk?

Wangchuk,59, is globally renowned as a passionate advocate for the environment and his home region and has also been involved in public demonstrations for greater constitutional safeguards for Ladakh.

An engineer, a climate activist, and an education reformer from Ladakh, Wangchuk is widely recognised for founding SECMOL and for developing the 'Ice Stupa' artificial glacier technique.

Wangchuk founded the Students' Educational and Cultural Movement of Ladakh (SECMOL) in 1988, an institution designed to transform the region's education system and equip youth with practical, sustainable life skills.

Wangchuk is celebrated for inventing the "Ice Stupa" project, which freezes and stores melting stream water into tall, cone-shaped ice towers to provide vital irrigation water for high-altitude trans-Himalayan villages during the spring.

Before the Jantar Mantar fast, Wangchuk has undertaken several hunger strikes over the years, mostly centred on environmental protection and on constitutional safeguards for Ladakh.

NSA revoked in March

In September 2025, for example, Wangchuk supported the Leh Apex Body (LAB) and Kargil Democratic Alliance (KDA) in pressing for statehood, Sixth Schedule status, and constitutional guarantees for Ladakh. He was on a hunger strike during the protest, which continued alongside negotiations with the Centre; Wangchuk rejected what he called 'delayed and inconclusive' talks.

The protest ended with violence, internet shutdowns, and Wangchuk's detention under the National Security Act (NSA). Wangchuk went to jail, but the Centre eventually revoked his NSA in March 2026.
