Discuss how India–Bangladesh inland water transit cooperation can reduce the Northeast's dependence on the Siliguri Corridor. What are the constraints?

The narrow Siliguri Corridor is the Northeast's only land link to the rest of India, which makes it a strategic and logistic chokepoint. The India–Bangladesh Protocol on Inland Water Transit & Trade (1972) [2] offers a river route around it. The first international cargo voyage from Dibrugarh since Independence, set for 5 October 2026, shows that this route is coming back into use [1].

How transit cooperation reduces dependence

• Alternative corridor: Protocol routes connect NW-2 (Brahmaputra, 891 km) and the Barak (NW-16) to Kolkata and Haldia ports through Bangladesh, bypassing Siliguri [2][3].
• Shared investment: the two countries are jointly developing the Sirajganj–Daikhowa and Ashuganj–Zakiganj stretches at about ₹305.84 crore [3]. Cargo on the Protocol route has grown 170% in about nine years [3].
• Direct export outlet: methanol from Assam Petro-Chemicals Ltd (APCL) will sail from Bogibeel to Pangaon (Dhaka) by water instead of going by road or rail through the Corridor [1].
• Cheaper, greener freight: the government promotes waterways as a "cheaper, greener and more efficient" mode for the Northeast [1].
• Strategic resilience: a second route keeps supplies moving if the Corridor is cut by landslides, blockades or security threats. It also builds mutual interdependence under the Act East policy.

Constraints

• Shallow channel: the depth the waterways authority (IWAI) maintains, called Least Available Depth, falls from 2.5 m (Dhubri–Neamati) to 2.0 m (Neamati–Dibrugarh). Keeping even that depth needs constant dredging of the braided, silt-heavy Brahmaputra [4].
• Reliance on Bangladesh's rivers: India does not control channel depth inside Bangladesh. Bangladesh has needed World Bank support to improve navigability on its own waterways [6].
• Weak demand-side conditions: a parliamentary Standing Committee named slow development, poor hinterland connectivity and costly vessels as the main deterrents [5].
• Small scale: waterways carry about 2% of India's freight, against 48% in Vietnam. Only 23 of 111 national waterways are operational [5].
• Political and ecological risk: the route depends on goodwill between the two countries, and repeated dredging harms the river's ecology.

Inland water transit cooperation can turn Bangladesh from a barrier into a bridge for the Northeast, but one ceremonial voyage does not make a trade route. The way forward has four parts:

• dredging contracts that pay for guaranteed depth rather than for silt removed
• joint maintenance dredging under the Protocol
• road and rail links to Bogibeel
• tracking regular, private-sector tonnage on the route

Together, these can move India towards Maritime India Vision 2030's target of a 5% share for waterways [7]. That would make "neighbourhood first" a working logistics route.
