Only a fraction of India's 111 National Waterways are operational. Analyse the technical, ecological and institutional constraints, and suggest a way forward.

India has declared 111 National Waterways (20,187 km), but only 32 are operational [1]. Just five NWs carry 80% of inland cargo, and waterways carry only about 2% of India's freight, compared with 14% in China [2]. Three linked sets of constraints explain this gap.

Technical constraints

• Not enough depth: Least Available Depth decides how deep a loaded vessel can sit (its draft) [1]. A parliamentary committee named low depth and a shortage of inland vessels as the main reasons water carries little freight [3].
• Silt and shifting channels: Braided rivers like the Brahmaputra keep shifting and silting up. They need thalweg surveys every week to month, now done on 22 NWs [1]. Dredging is therefore a recurring expense and a major part of both building and running costs [3].
• Poor links: Weak road and rail connections and high vessel costs keep shippers away [2].

Ecological constraints

• Harm to wildlife: Dredging and construction on NW-1 disturbed Gangetic dolphins [2].
• Not as green as it looks: Water freight is low-carbon per tonne [1], but repeated dredging disturbs the riverbed and its ecology.

Institutional constraints

• Too little money and staff: MoPSW has put 63 NWs on hold for lack of funds and staff [2].
• Unfinished projects: CAG found that ₹73.97 crore of dredging and ₹21.46 crore of terminals on NW-3 gave no benefit because some stretches were never finished [4].
• Dredging cost passed to ports: India adds dredging costs to port charges. In the US, the federal government pays 50–90% of them [3].
• Small-boat safety: Boat capsizings rose because of overloading and poor-quality boats [2].

Way forward

• Declare widely, develop selectively: Develop NWs that have cargo demand and enough depth. The committee called developing the 63 shelved NWs unviable for now [2].
• Pay for channels as a national asset: The Centre should fund dredging directly [3].
• Ecology first: Carry out environmental studies before developing an NW [2], and dredge only where survey data shows depth is short [1].
• Plan links from the start: Plan rail, road and port links at the planning stage, in line with PM Gati Shakti, and give shippers financial incentives [2].
• Safety for small operators: Provide a low-cost mobile navigation app and local weather-warning networks [2].

Depth, river ecology and limited money and staff together keep most declared waterways idle. Selective, ecologically careful and multimodal development, which builds on cargo of 218 MMT in 2025–26 [1], can move India towards its 5% modal-share target for 2030 [2]. This would advance SDG-9 and low-carbon logistics.
