Indus Waters Treaty strategic challenges CASS — these words captured the central warning of a high-level expert forum held in Islamabad on July 6, 2026, as the Centre for Aerospace & Security Studies convened its Catalyst Conversation on “The Future of the Indus Waters Treaty.”

The message from Pakistan’s foremost security and policy analysts was unambiguous: the 1960 treaty — once celebrated as one of the most durable transboundary water agreements in history — is now facing a confluence of legal, strategic, and climate-driven pressures that threaten its very survival.

India’s unilateral suspension of treaty obligations, its accelerating hydropower infrastructure on Pakistan’s western rivers, and the looming shadow of climate change have combined to create a crisis that demands urgent, coordinated Pakistani response — legal, diplomatic, and strategic.

2. About the CASS Catalyst Conversation

The Centre for Aerospace & Security Studies (CASS) is one of Pakistan’s leading independent think tanks, focused on security, strategic affairs, and policy research. Its Catalyst Conversation series brings together senior practitioners, policymakers, legal experts, and academics to examine complex national security challenges.

The July 6 session — conducted online — brought together experts with deep technical and legal knowledge of the Indus Waters Treaty to examine:

• The legal framework of the treaty and its current strain
• The historical evolution of Pakistan-India water disputes
• The strategic implications of India’s actions for regional stability
• Pakistan’s diplomatic and legal options going forward

The session was moderated by Director CASS, Air Marshal Hamid Randhawa (Retd), with the keynote delivered by former Pakistan Commissioner for Indus Waters Mirza Asif Baig — one of the country’s foremost technical experts on the treaty. CASS President Air Marshal Javaid Ahmed (Retd) delivered the concluding remarks.

3. Director CASS: A Treaty Tested to Its Limits

Opening the session, Air Marshal Hamid Randhawa (Retd) set the stakes plainly.

The Indus Waters Treaty, he acknowledged, has demonstrated remarkable durability over six decades — surviving wars between India and Pakistan in 1965, 1971, and 1999, as well as repeated diplomatic crises that would have shattered lesser agreements.

But that historical resilience, he warned, should not breed complacency. The treaty is now being tested in ways it was never designed to handle:

India’s suspension of treaty obligations — announced in 2025 following the Pahalgam attack — represents an unprecedented unilateral act that strikes at the foundational principle of treaty sanctity.

Expanding hydropower infrastructure on the western rivers — the Chenab, Jhelum, and Indus — is creating physical realities that will shape water flows regardless of what any court or commission decides on paper.

Climate-related pressures — including changing monsoon patterns, glacial melt acceleration, and increased frequency of extreme weather — are altering the hydrological conditions the treaty was designed to manage.

Randhawa stressed that Pakistan must respond to these compounding pressures not reactively, but through proactive, sustained engagement on regional water security diplomacy.

4. Keynote: Pakistan’s Objections and India’s Facts on the Ground

The substantive core of the CASS session was delivered by Mirza Asif Baig, who served as Pakistan’s Commissioner for Indus Waters — the country’s senior official responsible for managing the treaty relationship with India through the Permanent Indus Commission.

Baig’s assessment was measured but deeply sobering.

Pakistan has consistently raised formal objections to the design and operation of multiple Indian hydropower projects on the western rivers — the rivers allocated primarily to Pakistan under the treaty. These include projects on the Chenab (the Ratle Hydroelectric Plant) and the Jhelum (the Kishenganga Hydroelectric Project), among others.

Pakistan’s objections centre on whether the design specifications of these projects — dam heights, pondage capacities, operating curves — comply with the technical limits set out in the treaty’s Annexures. In Pakistan’s assessment, several do not.

What makes this particularly damaging, Baig explained, is India’s approach to the dispute resolution process.

5. India’s Deliberate Delay Tactics in Dispute Resolution

One of the most damning elements of Baig’s keynote was his characterisation of India’s conduct within the treaty’s dispute resolution mechanisms.

The Indus Waters Treaty contains a structured escalation framework for resolving disputes:

• Permanent Indus Commission (PIC): Regular bilateral meetings of senior commissioners from both countries
• Neutral Expert: A technical expert appointed to resolve engineering and design disputes
• Court of Arbitration: For disputes that cannot be resolved through the above mechanisms

Baig’s central charge: India has systematically delayed dispute resolution while continuing construction — effectively creating irreversible facts on the ground.

By the time a Neutral Expert or Court of Arbitration issues a ruling on the design of a project, the project is often already built. Infrastructure completed in violation of treaty specifications cannot easily be dismantled. The physical reality becomes permanent, regardless of what any international legal body says.

This strategy — delay proceedings, build fast — represents a calculated approach to eroding Pakistan’s treaty rights through infrastructure rather than negotiation.

Limited progress within the Permanent Indus Commission has compelled Pakistan to seek redress through the higher-level mechanisms, but these require lengthy proceedings that further advantage the party that has already built its infrastructure.

6. The Court of Arbitration and Neutral Expert Mechanisms

Despite the frustrations of slow proceedings, Pakistan has achieved meaningful legal victories through international mechanisms — and the Permanent Court of Arbitration (PCA) has played a central role.

In June 2025, the PCA issued a landmark Supplemental Award confirming that India cannot unilaterally hold the treaty in abeyance — directly repudiating India’s 2025 suspension announcement. A subsequent award placed substantive limits on India’s pondage capacity on the western rivers, ruling against India’s engineering assumptions for the Ratle and Kishenganga projects.

These rulings matter. They establish precedent, constrain India’s legal options, and validate Pakistan’s position in the international community.

But Baig’s point is that legal victories, however significant, cannot undo physical infrastructure already built. The law moves slowly; concrete moves fast. This is why Pakistan must pursue legal and diplomatic remedies simultaneously, and why it cannot afford to allow proceedings to drag while India continues building.

7. Why the IWT Remains the Only Game in Town

Despite all its limitations — the slow dispute resolution, India’s non-compliance, the gaps in addressing climate change — Baig was unequivocal on one point:

The Indus Waters Treaty remains the only internationally recognised framework governing the shared river system between Pakistan and India.

There is no alternative. No other bilateral agreement, no multilateral water-sharing framework, no customary international law arrangement provides the same level of specificity, legal enforceability, and institutional architecture as the 1960 treaty.

If the IWT collapses — through India’s sustained non-compliance, through formal abrogation, or through infrastructure that renders it meaningless in practice — Pakistan would be left with no binding legal framework to protect its access to the western rivers.

This is precisely why Pakistan must fight to preserve the treaty — not because it is perfect, but because losing it would leave Pakistan in a far worse position than reforming and enforcing it.

The International Court of Justice, the Vienna Convention on the Law of Treaties, and the UN Watercourses Convention all provide additional layers of protection — but none replicate the specific water allocation guarantees of the IWT.

8. India Politicising Water: A Dangerous New Precedent

CASS President Air Marshal Javaid Ahmed (Retd) struck a particularly grave note in his concluding remarks about the direction India has taken.

India is increasingly linking the treaty to political considerations — explicitly conditioning its treaty compliance on Pakistan’s behaviour regarding allegations of cross-border terrorism.

This is deeply dangerous for several reasons.

First, it violates the fundamental principle of pacta sunt servanda — the bedrock of international law that says treaties must be respected and implemented regardless of political disputes between the parties.

Second, it sets a catastrophic global precedent. If upper riparian states can suspend water treaties whenever they have political grievances against downstream neighbours, the entire architecture of international water law is at risk. Rivers cross borders; so do the consequences of weaponising them.

Third, it fundamentally undermines cooperative water management at a time when climate change is already reducing water availability across South Asia. The region needs more cooperation on water, not less.

Ahmed described India’s approach as a deliberate strategy to subordinate a legally binding water agreement to political leverage — and warned that allowing this precedent to stand unchallenged would have consequences far beyond Pakistan and India alone.

9. CASS President’s Call: Diplomacy, Law, and International Advocacy

Air Marshal Javaid Ahmed (Retd) closed the session with a clear three-pronged strategic recommendation for Pakistan:

Prioritise Water Security in Diplomatic Engagements Pakistan must elevate the IWT from a bilateral irritant to a core foreign policy priority — ensuring it features prominently in every multilateral engagement, from the UN General Assembly to COP climate summits to bilateral meetings with key partners.

Strengthen Legal Engagements Pakistan must continue pressing its case through the Permanent Court of Arbitration and explore additional legal avenues — including referral to the International Court of Justice — to create maximum legal pressure on India.

Build International Advocacy Pakistan is not alone as a lower-riparian state facing upstream pressure. By building coalitions with similarly situated countries — in Africa, Southeast Asia, Central Asia — Pakistan can elevate the water-weaponisation issue to a global governance challenge, not merely a bilateral dispute.

10. What Pakistan Must Do Now: A Strategic Roadmap

Drawing on the CASS experts’ recommendations, a coherent strategic roadmap for Pakistan on the Indus Waters Treaty strategic challenges CASS front would include:

Immediate Actions

• Accelerate PCA proceedings on pending disputes
• Document and publicise India’s ongoing construction activities as treaty violations
• Brief key UN Security Council members and G20 partners on the legal situation

Short-Term (6–18 Months)

• Complete and operationalise an integrated MRV (Monitoring, Reporting, Verification) system for western river flows
• Commission independent hydrological assessments of India’s hydropower projects’ actual impact on Pakistan’s water flows
• Develop a comprehensive legal brief on India’s violations for submission to international bodies

Medium-Term (2–5 Years)

• Pursue a multilateral lower-riparian coalition at the UN
• Invest in domestic water storage — dams, aquifer recharge, canal modernisation — to reduce vulnerability to upstream manipulation
• Engage the World Bank (as treaty guarantor) to formally assess India’s compliance obligations

11. Conclusion: Water Security Cannot Wait

The CASS Catalyst Conversation on the future of the Indus Waters Treaty strategic challenges CASS served as a timely and sobering reminder of the stakes involved.

The treaty has survived six decades of conflict, crisis, and political tension. But it has never faced the combination of pressures now arrayed against it: a hostile upstream neighbour willing to weaponise water for political gain, accelerating hydropower construction that creates irreversible physical facts, and a climate crisis that is shrinking the resource both sides are fighting over.

Pakistan’s legal position is strong. Its PCA victories are real. Its international advocacy is gaining traction. But legal victories on paper will not water Pakistan’s crops, fill its reservoirs, or protect its economy from the consequences of water deprivation.

What is needed is a whole-of-government, whole-of-society effort: legal, diplomatic, hydrological, infrastructural, and communicative. The IWT must be defended — in courtrooms, in diplomatic meetings, in international forums, and in the court of global public opinion.

Because as Pakistan’s own leaders have declared: water is not just a resource. It is a red line.
