India‑Bangladesh Relations Face a Crucial Test as the Ganges Water‑Sharing Treaty Nears Its End

When the Ganges‑Brahmaputra waters first started flowing across the porous border between India and Bangladesh, the two neighbours signed a pact in 1996 that promised a steady share of the river for the downstream country. Thirty years later, that agreement is ticking down to its last few months, and the stakes feel higher than ever.

At first glance it’s just a matter of cubic metres – 35,000 cusecs of water every day, as stipulated in the treaty, to keep rice paddies green and fish farms humming. But peel back the layers and you see a tangled web of agriculture, energy, climate change and politics, all converging on a single river that knows no borders.

Bangladesh, home to some of the world’s most densely populated low‑lying regions, depends on the Ganges for irrigation, drinking water and, crucially, for maintaining the delicate salinity balance in its delta. A shortfall of even a few thousand cusecs can translate into wilted crops, lower fish catches and, ultimately, higher food prices for a nation already grappling with rising inflation.

On the other side of the border, Indian states like West Bengal and Bihar look to the same river to power hydro‑electric projects and sustain their own agricultural cycles. Over the past decade, India has ramped up upstream infrastructure – from barrages to dams – ostensibly to boost its own water security. Critics argue that those projects shave off the flow that Bangladesh is legally entitled to under the 1996 deal.

And then there’s the climate factor. Glacial melt in the Himalayas, erratic monsoons and a warming atmosphere have made the Ganges’s annual discharge less predictable. In years of drought, the river’s total volume can shrink dramatically, turning the fixed‑allocation treaty into a zero‑sum game.

Politically, the timing couldn’t be more delicate. Recent weeks have seen a spate of border skirmishes, trade disputes over cotton and jute, and a lingering diplomatic chill after Bangladesh voiced concerns over India’s new river‑linking projects. While both capitals publicly affirm their “brotherly” relationship, the undercurrents are anything but calm.

What does renegotiation look like? Experts suggest a few possible pathways. One is to keep the same volume but introduce a flexible clause that allows adjustments based on annual flow – a sort of water‑budget that both sides can monitor via joint satellite data. Another suggestion is to broaden the conversation beyond sheer volume, incorporating water‑quality standards, joint flood‑control mechanisms and even joint‑venture hydro‑electric schemes that could benefit both nations.

There’s also a growing chorus calling for a third‑party mediator – perhaps the World Bank or a regional body like SAARC – to help draft a more resilient agreement. Such a move would signal a shift from bilateral bargaining to a more multilateral, science‑driven approach, something many climate‑policy analysts have been advocating for years.

Meanwhile, on the ground, farmers in Bangladesh’s Faridpur district are already feeling the pressure. “If the water recedes earlier than usual, we lose a whole season of rice,” says Abdul Karim, a farmer whose family has cultivated the same fields for generations. Across the border, a farmer in West Bengal’s Malda district voices a similar worry: “Our new irrigation canals need a reliable flow; otherwise, the whole project is a waste.”

These everyday voices underline why the treaty’s expiry is more than a diplomatic footnote. It’s a lived reality for millions whose livelihoods hinge on a river that both nations claim as their own.

So, as 2026 looms, the real test for India‑Bangladesh ties will be whether they can move past short‑term grievances and craft a forward‑looking, climate‑smart water‑sharing framework. The outcome could either reinforce a decades‑long friendship or expose fissures that could widen with each dry season.

One thing is certain: the Ganges will keep flowing, indifferent to politics. It will be up to the people on its banks to decide if they can share its bounty peacefully, or if the river becomes a source of fresh discord.
