Why in the news?

The Union Minister of Ports, Shipping and Waterways has outlined a comprehensive plan to transform the Brahmaputra River into a global river tourism and trade hub under the Ministry of Ports, Shipping and Waterways. This initiative seeks to revive the river’s historical role as a vital channel of connectivity, commerce, and culture in the Northeast region.

Historical Context

The Brahmaputra (Luit) has for centuries been the lifeblood of Assam — a natural highway that connected communities, fostered trade, and shaped its civilization.

  • Ancient inscriptions such as the Vanamala copper plate (9th century) and the Tezpur rock edict (7th century) record dense boat traffic and organized taxation systems on river routes.
  • During the Ahom era (13th–19th century), the river played a strategic role in warfare and trade. 
    • The Battle of Saraighat (1671), led by Lachit Borphukan, demonstrated the Ahoms’ naval ingenuity.
  • Under British rule, the Brahmaputra-Ganga waterway remained a key route for transporting tea, timber, and goods to Kolkata. 
    • River steamers operated till the 1965 Indo-Pak war, after which the route was disrupted.

The Brahmaputra River

Origin and Course

  • The Brahmaputra originates from the Angsi Glacier (near Mansarovar Lake) in southern Tibet.
  • In Tibet, it is known as the Yarlung Tsangpo (or Tsangpo River), meaning “the purifier.”
  • It flows eastward parallel to the Himalayas for about 1,625 km, before taking a sharp U-turn (known as the Great Bend) near Namcha Barwa Peak (7,782 m) and enters India through Arunachal Pradesh, where it is called the Siang (or Dihang).
  • After flowing through Assam, it enters Bangladesh, where it is known as the Jamuna, before merging with the Ganga (Padma) and finally forming the world’s largest delta — the Sunderbans Delta — before emptying into the Bay of Bengal.

Countries and States through which it Flows

  • Countries: Tibet (China), India, Bangladesh
  • Indian States:
    • Arunachal Pradesh (as Siang/Dihang)
    • Assam (as Brahmaputra)

Point of Entry into India

  • The river enters India near Gelling in Arunachal Pradesh.

Catchment and Drainage Area

  • Total length: ~2,900 km (916 km in India)
  • Total catchment area: ~580,000 sq. km
    • India: ~195,000 sq. km
    • Assam basin: ~70,000 sq. km
  • Basin states in India: Arunachal Pradesh, Assam, Meghalaya, Nagaland, Sikkim, and parts of West Bengal.

Major Tributaries

Right Bank Tributaries (from north):

  1. Subansiri – largest right-bank tributary; source of major hydropower projects.
  2. Kameng
  3. Manas – originates in Bhutan; famous for Manas National Park.
  4. Sankosh 
  5. Raidhak
  6. Jaldhaka

Left Bank Tributaries (from south):

  1. Dibang
  2. Lohit – joins near Sadiya (where Dihang, Dibang, and Lohit meet to form the Brahmaputra).
  3. Dhansiri (South)
  4. Kopili
  5. Burhidihing

Various Name of Brahmaputra as Per Ancient Source:

  • Hiranyo
  • Varidhi
  • Sarit Abhipat
  • Lauhitya
  • Mandakini
  • Hridini
  • Khatai
  • Brahmi 
  • Karkaya
  • Digama

Modern Revival

The government’s initiative seeks to revive the Brahmaputra’s navigational, commercial, and ecological vitality.
Key measures include:

  • Maintenance of fairways and dredging to ensure smooth navigation.
  • Construction of modern terminals at Pandu, Dhubri, Jogighopa, and Bogibeel, and floating jetties at key river points.
  • Development of 85 community jetties for local trade and passenger movement.
  • Integration of road, rail, and water networks for multimodal connectivity under the National Waterway-2 (NW-2) framework.
  • Promotion of river tourism, highlighted by the successful Ganga Vilas Cruise (Varanasi–Dibrugarh, 3,200 km), showcasing India’s longest river voyage through the Brahmaputra.

Significance for Assam and the Northeast

  • Economic Integration: Reviving river transport can significantly reduce logistics costs and enhance trade with Bangladesh and Southeast Asia under the Act East Policy.
  • Tourism Growth: Plans to establish the Brahmaputra as a global cruise destination will boost eco-tourism and cultural tourism, creating jobs in hospitality and allied sectors.
  • Sustainable Development: Encourages green transport, reducing pressure on road and rail infrastructure.
  • Community Empowerment: Community jetties will serve as local trade hubs, connecting rural artisans, farmers, and small traders to regional markets.

Challenges Ahead

  • Siltation and seasonal floods affect navigation and infrastructure stability.
  • Ecological sensitivity of the riverine ecosystem demands sustainable dredging and waste management.
  • Coordination gaps among states and agencies could delay implementation.
  • Need for capacity-building and modern vessel technology for efficient operations.

Frameworks and Policies

  • Inland Waterways Authority of India (IWAI) under the Inland Waterways Act, 2016.
  • National Waterway-2 (NW-2): Brahmaputra River from Dhubri to Sadiya (891 km).
  • PM Gati Shakti Mission: For integrated infrastructure planning.
  • Sagarmala Programme: Strengthening ports and waterways for trade and tourism.

Exam Hook: Key Takeaways

  • Project: Rejuvenation of the Brahmaputra under the Ministry of Ports, Shipping and Waterways.
  • Objective: Transform the river into a hub of trade, tourism, and connectivity.
  • Infrastructure: 85 jetties, terminals at Pandu, Dhubri, Jogighopa, Bogibeel; multimodal links.
  • Alignment: With National Waterway-2, Sagarmala, and Act East Policy.
  • Significance: Revives Assam’s historical waterway network; promotes eco-tourism and regional integration.

Mains Question:
Discuss the economic and cultural significance of the Brahmaputra River and the challenges involved in its revival as a national waterway.

One-line wrap: The rejuvenation of the Brahmaputra bridges Assam’s glorious past with its modern aspirations — steering the Northeast toward a future of connectivity, commerce, and sustainable growth.
