#1
The Sagarmala Programme, approved in March 2015, coordinates over 800 projects to reduce logistics costs for domestic and foreign trade.
#2
Sagarmala is structured around four core pillars: port modernization, port connectivity, port-linked industrialization, and coastal community development.
#3
Coastal Economic Zones (CEZs) are spatial industrial clusters designated under Sagarmala to manufacture goods within port hinterlands for direct maritime export.
#4
National Waterway 3 (NW-3) covers 205 kilometres in Kerala, running from Kottapuram to Kollam via the historic West Coast Canal system.
#5
NW-3 incorporates the Udyogmandal and Champakara canals in Kochi, providing container barges with direct water access to Cochin Port.
#6
NW-3 was the first National Waterway in India to provide round-the-clock 24-hour navigational aids and lighted buoys across its entire length.
#7
National Waterway 4 (NW-4) spans 2,890 kilometres, linking the Krishna and Godavari rivers with the Kakinada Canal and Buckingham Canal.
#8
The Buckingham Canal, constructed in 1806 during British rule, forms the southern saltwater navigational spine of NW-4 extending to Puducherry.
#9
National Waterway 5 (NW-5) measures 623 kilometres across Odisha and West Bengal along the Brahmani River, Matai River, and the East Coast Canal.
#10
NW-5 is designed to transport heavy industrial cargo, thermal coal, and iron ore from the Talcher and Sukinda mining belts to Paradip Port.
#11
Water freight transit consumes 1 litre of fuel to transport 105 tonne-kilometres of cargo, compared to 85 on rail and 24 on road.
#12
Inland water transport produces roughly 32 to 36 grams of carbon dioxide per tonne-kilometre, approximately half the emission level of rail transport.
#13
Roll-on/Roll-off (Ro-Ro) and Roll-on/Passenger (Ro-Pax) vessel services launched under Sagarmala reduce overland road transit across the Gulf of Khambhat in Gujarat.
#14
The PM Gati Shakti National Master Plan integrates National Waterways 1 through 5 with Western and Eastern Dedicated Freight Corridors to create unified logistics nodes.
#15
The National Technology Centre for Ports, Waterways and Coasts (NTCPWC) was established at IIT Madras in 2018 as the premier research body for maritime engineering.
Subject Specialist Commentary
Analytical perspective & practical exam advice from the Master10 academic board
Maritime transport and inland waterways handle the majority of India's international trade volume and domestic bulk freight. To modernize this infrastructure, the Ministry of Ports, Shipping and Waterways launched the Sagarmala Programme in 2015, focusing on port modernization, industrial coastal zones, and seamless multimodal rail-road connectivity. Along with major sea gateways like Mumbai and Chennai, India has developed inland waterways under the Inland Waterways Authority of India, transforming major river courses into cost-effective navigation channels.
In UPSC Prelims and State PSC exams, candidates are often tested on National Waterways and port characteristics. Memorize the major inland routes: National Waterway 1 on the Ganga stretches from Prayagraj to Haldia as the country's longest waterway, while National Waterway 2 spans the Brahmaputra between Sadiya and Dhubri. A frequent exam trap confuses port classifications: remember that major ports fall under Union jurisdiction, whereas non-major ports are managed by state maritime boards under the Concurrent List.
