Who is Katon Moyong? Inside the Viral Battle Against Arunachal's Siang Mega Dam

Short answer: Katon Moyong, an environmental engineer known locally as Abor Man, has captured nationwide attention with a fiery speech opposing the proposed 11,000-megawatt Siang mega dam in Arunachal Pradesh. While the central government argues that the mammoth dam is essential for national security to counter Chinese hydro-projects upstream in Tibet, indigenous Adi villagers fear the reservoir will submerge dozens of ancestral villages and erase their ancient homeland. Moyong’s viral declaration that indigenous tribes lived along the river long before modern borders existed has transformed a remote river dispute into a major national debate over tribal sovereignty and borderland development.

1. Who is Katon Moyong, the ‘Abor Man’ of Arunachal?

To understand why this issue is suddenly trending across India, one must first look at the man behind the microphone.

Katon Moyong, sometimes called Moyong Katon, is an environmental engineer and grassroots activist belonging to Arunachal Pradesh’s indigenous Adi community. He leads the youth wing of the Siang Indigenous Farmers Forum (SIFF), an organization that has spearheaded opposition to mega-dams in the region for decades.

Moyong is not an armchair critic who only posts online:

• Walking 56 remote villages: Across 2024 and 2025, Moyong traveled on foot to 56 different villages tucked inside the rugged Siang River valley. He met with village elders, held open community discussions, and documented local signatures opposing government surveys.
• Known as Abor Man: His tireless grassroots mobilization earned him the popular community title Abor Man, referencing the historic term for the indigenous hill tribes of the Eastern Himalayas.
• Detention in New Delhi: In late October 2026, Moyong traveled to New Delhi to stage peaceful demonstrations and submit memorandums to central ministries. He was detained by police alongside other northeastern activists, an action that sparked outrage across tribal groups back home.
• The viral Itanagar press briefing: Shortly after returning from detention, Moyong held an explosive press conference at the Arunachal Press Club in Itanagar on November 5. Dressed in traditional Adi woven attire and ceremonial turquoise beads, he stood with arms wide open, issuing an uncompromising message directly to Chief Minister Pema Khandu: “We have been saying no to the Siang dam for 47 years.”

Within hours, video clips of his speech spread like wildfire across social media platforms, turning a localized struggle into a national talking point.

2. What is the hassle around the 11,000 MW Siang mega dam?

The Siang River is the lifeblood of northeastern India. Originating in the glaciers of southern Tibet, where it is known as the Yarlung Tsangpo, the river surges eastward through the deepest gorges on Earth before crossing into Arunachal Pradesh as the Siang. Downstream in Assam, it merges with other rivers to form the mighty Brahmaputra.

For decades, the central government has planned to build the Siang Upper Multipurpose Project (SUMP), an engineering behemoth designed to generate approximately 11,000 megawatts of electricity.

The clash comes down to two completely opposing worldviews:

The Central Government’s Rationale: Strategic Defense Against China New Delhi’s push for the Siang mega dam is driven primarily by intense geopolitical anxiety. Just across the Line of Actual Control in Medog, Tibet, China is currently constructing a colossal 60,000-megawatt super-dam on the Great Bend of the Yarlung Tsangpo. Indian security planners worry that Beijing could use this upstream dam as a hydro-weapon, withholding vital water during dry winters or releasing sudden torrents to trigger devastating flash floods downstream in Assam and Arunachal.

Government officials argue that building an 11,000 MW dam with a massive reservoir inside Indian territory is the only way to buffer unexpected water surges, regulate river flow, and establish legally recognized prior water use rights under international law.

The Indigenous Community’s Nightmare: Total Submergence and Displacement While New Delhi views the project through the lens of national defense, local Adi families see it as an existential threat to their survival:

• Submerging 60+ ancestral villages: Independent hydrological models indicate that an 11,000 MW dam reservoir would submerge dozens of ancient villages, thousands of hectares of terraced agricultural land, sacred burial grounds, and historical community trails.
• Fragile seismic zone: The Eastern Himalayas are one of the most earthquake-prone regions in the world. Local activists and geologists warn that anchoring a monster concrete dam in fragile tectonic terrain risks catastrophic failure, threatening millions of lives downstream in Assam.
• Heavy police deployment: To carry out preliminary drilling and geological surveys, the state government deployed central paramilitary troops into rural districts. Villagers viewed the armed presence as an attempt to force the project onto them without consent.

Tensions over strategic infrastructure in borderlands mirror broader debates surrounding indigenous land rights and troop deployments across Arunachal Pradesh.

3. What is Katon Moyong asking and stating?

The most powerful section of Moyong’s speech challenged the central government’s habit of using national security to silence local dissent.

During the press briefing, Moyong delivered a line that resonated deeply with indigenous communities across the country:

“India was born in 1947 and China in 1949. We have been living here much before that.”

His point was simple yet profound. The indigenous people of the Siang valley are not chess pieces in a modern geopolitical contest between two nuclear-armed states. Their historical existence and constitutional land rights predate both modern republics, and their homeland cannot simply be sacrificed as a defensive moat.

Moyong outlined four non-negotiable demands:

• Stop all surveys immediately: The state government and public sector power corporations must halt all exploratory drilling, pre-feasibility surveys, and heavy machinery movements in the Siang valley.
• Mandatory Kebang approvals: Under traditional tribal law, no developmental activity can take place without the formal approval of the Kebang (the ancient village council). Moyong demanded that the government secure written consent from all 60 affected village councils before holding any further discussions.
• Release protesters and withdraw forces: The government must drop charges against detained anti-dam protesters and withdraw paramilitary units stationed around survey sites.
• Micro-hydro over mega-dams: Moyong clarified that the Adi people are not opposed to clean energy. They actively support small run-of-the-river hydropower projects on tributary streams that do not submerge villages. What they reject is a monster dam on the main stem of the sacred Siang.

Similar clashes between major energy corporations and local forest communities have surfaced in central India, as seen during intense grassroots opposition to large-scale power infrastructure.

4. The Adi people and why the Siang River is their identity

To understand the intensity of the resistance, one must appreciate the deep cultural bond between the Adi community and the river.

The Adi are one of the largest indigenous tribal communities in Arunachal Pradesh, living along the mountain slopes of the Siang valley for centuries. Their oral folklore traces their ancestral roots to Abo Tani, the mythical forefather of several Himalayan tribes.

The community lives by unique cultural and democratic traditions:

• The Kebang system: Long before British colonial rule or Indian statehood, Adi villages governed themselves through the Kebang. In this traditional village assembly, every resident has a voice, and community disputes are settled through consensus rather than bureaucratic decree.
• The Donyi-Polo faith: Many Adi people practice Donyi-Polo, a spiritual tradition that reveres the Sun (Donyi) and the Moon (Polo) as symbols of truth, cosmic harmony, and nature. Seasonal festivals like Solung celebrate agriculture, fertility, and gratitude for the earth.
• A living ancestor: For the Adi, the Siang River is not a resource to be measured in megawatts or cubic meters of water. It is a living ancestor that shapes their songs, oral histories, clan boundaries, and farming rhythms. Drowning the river valley means drowning their history.

Transboundary river dynamics and extreme weather risks have increasingly complicated Himalayan water security, as seen in early warning telemetry limits across Himalayan river basins.

Chief Minister Pema Khandu has acknowledged that local communities must be consulted and taken into confidence before moving forward. However, with Katon Moyong and the Siang Indigenous Farmers Forum taking an unyielding stand, the battle over the Siang River has reached a decisive crossroads. The central government now faces a delicate choice between pushing an 11,000 MW strategic shield or honoring the democratic consent of the indigenous people who have guarded the Himalayas for centuries.
