Will South Asian water disputes veer into cooperation?  

In South Asia, rivers are no longer mere watercourses; they are now the arteries of politics, economics, and diplomacy. The Ganges, Brahmaputra, Meghna, and Indus systems carry not only water but also agriculture, power generation, food security, transport, and trade. Among more than 600 rivers flowing across the region, about 54 cross international boundaries to enter Bangladesh-making this delta the final downstream hub of South Asia's hydrological network.

This geography has granted Bangladesh an exceptional geopolitical position: the water that sustains one-fifth of the world's population eventually flows through its plains into the Bay of Bengal. Thus, river governance is no longer a domestic concern-it has become the foundation of hydro-diplomacy, the art of turning shared water into shared prosperity.

From Water Politics to Hydro-Diplomacy: For decades, South Asian nations engaged in water disputes. Upstream countries-India, Nepal, and Bhutan-built dams for irrigation and hydropower; downstream Bangladesh struggled with reduced flow and silted channels. Today, the conversation is shifting from conflict to cooperation.

Rivers as Corridors of Regional Commerce: River connectivity can redraw the economic map of South Asia. The 1972 Bangladesh-India Inland Water Transit and Trade Agreement opened an historic route from Haldia Port in West Bengal to Assam via Bangladesh. About 2.5 million tonnes of goods-food-grains, fertiliser, stone, coal, iron, and other bulk cargo-now move along this channel each year.

If the Nabaganga-Gorai-Padma alignment is restored, more than 20 districts in south-western Bangladesh will gain direct access to an international waterway, linking agriculture in the north to industries and ports in the south. Such a corridor would integrate markets, cut transport costs, and generate thousands of new jobs.

“Geographically, Bangladesh sits at the heart of every regional current. All upstream waters converge here before meeting the Bay of Bengal. This makes the country both vulnerable and powerful: the health of regional rivers determines its economy, while its waterways determine regional access to the sea.”

Bangladesh's restoration of flow benefits India's northeast by reducing sediment and improving drainage; it supports Nepal's hydropower stability and Bhutan's flood management. This is the new hydro-cooperation doctrine-competition replaced by necessity, rivalry replaced by reason.

Bangladesh: The Flowing Centre of South Asia: Geographically, Bangladesh sits at the heart of every regional current. All upstream waters converge here before meeting the Bay of Bengal. This makes the country both vulnerable and powerful: the health of regional rivers determines its economy, while its waterways determine regional access to the sea.

If India ships goods from its northeast to Kolkata, the journey costs about Tk 2,000 per tonne and takes two weeks; using Bangladeshi rivers cuts cost to Tk 1,000 and time to five days. Such efficiency turns Bangladesh into a River-Transit Power-a logistical hub through which the subcontinent's trade can breathe.

From Deep-Sea Ports to Rural Wharves: Connecting Mongla and Chattogram ports with inland waterways would transform Bangladesh into a seamless logistics network. Foreign ships could unload cargo at seaports, transfer it to lighter vessels, and move it upriver to Kushtia, Rajbari, Jhenaidah, Faridpur, and beyond.

Each river wharf would evolve into a local port-creating micro-economies of storage, small industry, and labour. Currently, hauling a truckload of goods from Mongla to Dhaka costs about Tk 25,000; by river, the same shipment would cost Tk 12,000 and take half the time. Every active wharf could generate Tk 20-25 crore in local revenue per year. Where rivers flow, prosperity follows.

Policy Vision: Building the Hydro-Diplomacy Corridor: Rivers are now central to Bangladesh's foreign and economic policy. The government should adopt a National Hydro-Diplomacy Policy, declaring rivers as strategic assets for revenue and regional cooperation.

Key measures must include: a unified budget for river restoration and connectivity; a multi-ministry National River Council linking transport, water resources, environment, agriculture, industry, and commerce; upstream-downstream treaties with India, Nepal, and Bhutan for water sharing, joint dredging, navigation, and hydropower; an international River Finance Fund blending foreign investment and climate aid; and the establishment of River-Port Industrial Zones in every navigable district.

If implemented, more than 40 districts would gain direct waterway access, transport costs would fall 40 per cent, at least 100,000 jobs would emerge, and national revenue would rise by Tk 10 billion annually. Above all, Bangladesh would assume leadership in South Asia's hydro-diplomacy-where rivers symbolise peace, flows symbolise trust, and shared water becomes shared growth.

"A river is no longer just water; it is power, politics, and the promise of peace. Bangladesh now stands at the confluence-ready to lead South Asia's next great flow."
