N4S: This article explains the Indus Water Treaty and its recent challenges in clear, simple terms. UPSC often frames questions on such topics by linking them to current geopolitical tensions, legal frameworks, and bilateral relations. For example, previous questions have asked about maritime disputes and the importance of safeguarding navigation, which requires understanding of broader strategic issues and specific bilateral tensions (like India-China relations in the South China Sea). Aspirants often falter by memorizing treaty provisions without connecting them to real-world events or failing to understand the dispute resolution mechanisms under the treaty (such as the role of the Permanent Indus Commission or Neutral Expert). This article helps by breaking down complex ideas like “holding the treaty in abeyance” and why it has no clear legal basis under international law, using simple language and specific examples like the 2016 Pakistan bypass of the Neutral Expert stage. It also highlights how water has become a diplomatic tool and weapon, a concept many aspirants miss because they don’t link resources to international diplomacy (for example, India’s response after terror attacks by signaling water restrictions). One special feature of this article is its clear explanation of the three-tier dispute resolution process and how India and Pakistan have used or bypassed these mechanisms, which helps aspirants answer both conceptual and current-affairs-based questions with confidence. Overall, this article makes a tough topic accessible, showing the connections between history, law, and geopolitics, which is exactly how UPSC tests aspirants.

This article explores the Indus Water Treaty and its recent challenges by linking it to broader themes of geopolitics, international law, and India-Pakistan relations. UPSC often frames such topics around strategic issues, as seen in questions on maritime disputes or resource-based diplomacy. Aspirants usually falter by focusing only on treaty provisions, missing how these relate to current events or dispute resolution mechanisms like the Permanent Indus Commission or the Neutral Expert.

The article explains ideas such as “holding the treaty in abeyance” and highlights past examples like Pakistan bypassing the Neutral Expert in 2016. It also discusses how water has become a diplomatic tool. With a focus on real events and structured analysis, it helps aspirants tackle both static and dynamic dimensions effectively.

MICROTHEME: BILATERAL RELATIONS

“Rivers don’t just carry water. They carry history, power—and sometimes, revenge.”

Signed in 1960, the Indus Water Treaty was hailed as a miracle of diplomacy between two hostile neighbours—India and Pakistan. For over six decades, even through wars and terror strikes, the treaty held firm, insulated from political tempests.

Until now.

After the brutal Pahalgam attack that claimed the lives of Indian soldiers, Delhi has done the unthinkable—moved to suspend parts of the treaty. For the first time in history, water is being used not just as a resource, but as a weapon.

So what does this mean for India, for Pakistan—and for the fragile peace in South Asia?
Is this strategic pressure or a dangerous escalation?
And above all: once water becomes war, can there ever be peace again?

Key Reasons Cited by India for Holding the Indus Waters Treaty (IWT) “in Abeyance”

• Fundamental Change in Circumstances: India argues that since the treaty’s signing in 1960, there has been a drastic shift in population demographics and developmental needs, especially the urgent requirement for clean energy. Eg: India’s push for hydropower projects on western rivers like Kishanganga and Ratle reflects its clean energy goals.
• Violation of Good Faith Principle: India claims that Pakistan has not acted in good faith, as evidenced by its continuous sponsorship of cross-border terrorism, which undermines mutual trust required under international treaties. Eg: The recent Pahalgam terror attack is cited as part of a pattern of hostile actions.
• Obstruction in Treaty Implementation: India points to Pakistan’s resistance and obstructionist approach in dispute resolution and infrastructure development under the treaty framework. Eg: In 2016, Pakistan bypassed the Neutral Expert process and approached the Permanent Court of Arbitration directly, delaying dam projects.

Legal Invalidity of the Term “Hold in Abeyance” Under International Law:

• “Abeyance” Not Recognised in VCLT Terminology: The VCLT only recognises terms like “termination” and “suspension” of treaties—not “abeyance.” Hence, “holding a treaty in abeyance” has no formal legal status or procedural clarity under international law. Eg: Article 62 of the VCLT provides for treaty termination due to fundamental change in circumstances, but does not mention or define “abeyance.”
• High Threshold for Fundamental Change: Even under Article 62, “fundamental change in circumstances” must directly relate to the core purpose of the treaty, and meet strict criteria set by international jurisprudence, particularly the ICJ. Eg: In the 1984 Nicaragua v. United States case, the ICJ rejected the US claim that a political shift in Nicaragua was a fundamental change justifying treaty exit.

Dispute Resolution Mechanism Under the Indus Waters Treaty:

• Permanent Indus Commission (PIC) – First Tier: Both India and Pakistan appoint Commissioners who meet regularly to resolve technical and implementation issues bilaterally. This is the first step in resolving disputes. Eg: Disagreements over annual data sharing or small projects are often addressed at this level.
• Neutral Expert – Second Tier: If the issue remains unresolved, either country can request the World Bank to appoint a Neutral Expert for technical matters such as design parameters of projects. Eg: In 2005, a Neutral Expert was appointed to resolve the Baglihar Dam dispute between India and Pakistan.
• Permanent Court of Arbitration (PCA) – Third Tier: If the issue is legal or political, or if technical resolution fails, the matter can be escalated to the Permanent Court of Arbitration, facilitated by the World Bank. Eg: In 2016, Pakistan skipped the Neutral Expert stage and approached the PCA over the Kishanganga and Ratle projects, which India opposed.

Transboundary Water Disputes

Transboundary water disputes occur when rivers, lakes, or groundwater basins flow across the boundaries of two or more countries, creating competition over access, usage, and control. As freshwater becomes scarcer due to climate change, population growth, and industrial demands, such disputes are becoming more frequent and politically sensitive. While international law encourages cooperation through treaties, the absence of enforcement mechanisms often turns shared water resources into contested geopolitical flashpoints. South Asia, Africa, and the Middle East are particularly vulnerable to such disputes due to legacy borders and high water dependency.

Major Transboundary Water Disputes

Water Wars in South Asia

In South Asia, where river systems transcend national boundaries, water is not merely a resource—it is a strategic asset tied to food security, energy generation, and political stability. Most countries in the region depend on rivers that originate beyond their borders, creating deep interdependence but also significant tension. While outright wars over water have not occurred, the region has witnessed recurring diplomatic friction, data withholding, dam-based disputes, and the politicization of river treaties. In several cases, water has become an extension of unresolved border conflicts or trust deficits between neighbours.

Water Tensions in India’s Neighbourhood

Using Natural Resources as Diplomatic Tools

Throughout history, nations have used their control over natural resources not just for economic gain but as tools of diplomacy, pressure, or retaliation. This strategic use—also known as resource weaponization—has extended to water in recent decades. When treaties are threatened, data is withheld, or river flow is altered for political messaging, water becomes a bargaining chip in regional politics. India’s evolving stance on the Indus Waters Treaty after major terror attacks is one example. Globally, countries have used oil, gas, rare minerals, and even food exports to signal intent, extract concessions, or punish adversaries—all without firing a shot.

#BACK2BASICS : INDUS WATER TREATY

Indus Water Treaty: Overview and Key Provisions

The Indus Water Treaty (IWT), signed in 1960, governs the water-sharing arrangements between India and Pakistan over the Indus River system. The Treaty emerged as a solution to water disputes following the partition of India in 1947, which divided the river system between the two nations.

Key Provisions of the Indus Water Treaty

1. Water Sharing Arrangement:
   • The six rivers in the Indus Basin were divided as follows:
     • Western Rivers: Indus, Jhelum, and Chenab were allocated to Pakistan for unrestricted use, except for specified uses by India (e.g., non-consumptive, agricultural, and domestic uses).
     • Eastern Rivers: Ravi, Beas, and Sutlej were allocated to India for unrestricted use.
   • Approximately 80% of the water flow was allocated to Pakistan and 20% to India.
2. Specific Rights for India on Western Rivers:
   • Annexure C: Grants India rights for limited agricultural usage of waters from the western rivers.
   • Annexure D: Allows India to build ‘run-of-the-river’ hydropower projects (HEPs), which do not involve live water storage.
     • India must adhere to detailed design specifications.
     • Pakistan must be informed about project designs and can raise objections within three months.
3. Storage Provisions: India is permitted minimal storage on the western rivers for conservation and flood control purposes.
4. Permanent Indus Commission
   • A Permanent Indus Commission was established under the Treaty, comprising representatives from both nations.
   • Functions: Act as the first step in resolving water-related conflicts and Mandate at least one annual meeting.
5. Dispute Resolution Mechanism: The IWT outlines a three-step graded dispute resolution mechanism:
   • Permanent Indus Commission/Inter-government Talks: Initial disputes should be resolved through the Commission or inter-government dialogues.
   • Neutral Expert (NE): Unresolved disputes may be referred to the World Bank, which can appoint a Neutral Expert to resolve specific issues.
   • Court of Arbitration (CoA): If disputes involve treaty interpretation or dissatisfaction with the NE’s decision, they may be referred to a Court of Arbitration.
