What Happened
- Union Minister for Ports, Shipping and Waterways Sarbananda Sonowal laid the foundation stones for four riverine lighthouses along the Brahmaputra River (National Waterway 2)
- These are the first lighthouse structures to be installed on an inland waterway in India
- The four lighthouses will be located at Pandu, Bogibeel, Silghat, and Biswanath Ghat in Assam
- The project has an investment of Rs 84 crore and will be implemented by the Directorate General of Lighthouses and Lightships (DGLL) in collaboration with the Inland Waterways Authority of India (IWAI)
- Each lighthouse will be 20 metres tall, solar-powered, and capable of guiding vessels up to 14 nautical miles geographically and 8-10 nautical miles through luminous range

National Waterways and the Inland Waterways Authority of India (IWAI)
India's inland waterway transport is governed by the Inland Waterways Authority of India (IWAI), established in 1986 under the Inland Waterways Authority of India Act, 1985. The National Waterways Act, 2016, declared 111 waterways as National Waterways, a massive expansion from the original 5.
- IWAI: Established 1986; HQ: Noida, Uttar Pradesh; operates under the Ministry of Ports, Shipping and Waterways
- National Waterways Act, 2016: Declared 111 National Waterways (up from 5)
- The original 5 National Waterways:
- NW-1: Ganga-Bhagirathi-Hooghly (Prayagraj to Haldia, 1,620 km) — declared 1986
- NW-2: Brahmaputra (Dhubri to Sadiya, 891 km) — declared 1988
- NW-3: West Coast Canal (Kottapuram to Kollam, 205 km) — declared 1993
- NW-4: Kakinada-Puducherry canals (1,095 km) — declared 2008
- NW-5: Brahmani-Mahanadi delta (623 km) — declared 2008
- Jal Marg Vikas Project: Rs 5,369 crore project on NW-1 for navigation capacity development (assisted by World Bank)
- Inland waterways carry less than 2% of India's total freight compared to 20% in the EU and 47% in China
- Comprehensive development of NW-2 was taken up by IWAI at a cost of Rs 474 crore during 2020-21 to 2024-25
Connection to this news: The riverine lighthouse project on NW-2 represents a significant step in making the Brahmaputra navigable for 24/7 commercial operations. India's inland waterways carry a disproportionately low share of freight, and infrastructure investments like lighthouses address the navigation safety gaps that have held back waterway utilization.
The Brahmaputra River System: Geography and Significance
The Brahmaputra is one of the world's major river systems, flowing approximately 2,900 km through Tibet (where it is known as Tsangpo), India (Assam), and Bangladesh (where it becomes the Jamuna). It is an antecedent river that predates the Himalayan orogeny.
- Origin: Near Angsi Glacier in Tibet, close to Lake Mansarovar
- Length: approximately 2,900 km (approximately 916 km in India)
- The Brahmaputra flows eastward in Tibet, takes a sharp U-turn near Namcha Barwa (known as the Dihang gorge), then flows southwest through Arunachal Pradesh and westward through Assam
- Major tributaries in India: Subansiri, Kameng, Manas, Dhansiri, Lohit, Dibang
- The Brahmaputra carries the highest sediment load among Indian rivers, contributing to frequent flooding in Assam
- Majuli, in the Brahmaputra, is the world's largest river island
- The river is a transboundary waterway shared by China, India, and Bangladesh, making it geopolitically significant
- China's dam-building activities on the Tsangpo (Brahmaputra) in Tibet are a concern for downstream nations
Connection to this news: The lighthouse project at four locations along the Brahmaputra's course in Assam will enhance navigation safety on a river known for its high sediment load, shifting channels, and seasonal flooding. The 891-km NW-2 stretch offers significant untapped potential for cargo movement and tourism in the Northeast.
Sagarmala Programme and India's Port-Led Development
The Sagarmala Programme, launched in 2015 by the Ministry of Ports, Shipping and Waterways, aims to promote port-led development through modernization of existing ports, new port development, port connectivity enhancement, port-linked industrialization, and coastal community development.
- Sagarmala launched: April 2015; estimated investment: Rs 8 lakh crore across 800+ projects
- India has 12 major ports (under the Major Port Authorities Act, 2021) and approximately 200 non-major/minor ports
- Major ports handle approximately 55% of India's maritime cargo
- The Maritime India Vision 2030, released in 2021, aims to boost India's port capacity to 3,300+ MTPA
- India's coastline: approximately 7,517 km (including mainland and island coastline)
- National Maritime Heritage Complex (NMHC) at Lothal, Gujarat — under development
- India's share in global shipping: approximately 1% of the world fleet but handles significant trade volumes
Connection to this news: The Brahmaputra lighthouse project aligns with Sagarmala's objective of developing inland waterways as an alternative freight corridor. Improved navigation infrastructure on NW-2 supports the programme's goal of reducing logistics costs and enhancing connectivity to India's landlocked Northeast region.
