Key Points
- Treaty has insulated water cooperation from political conflict for decades
- India’s move to place it in abeyance risks destabilising regional balance
- Weakening data-sharing and dispute mechanisms fuel strategic uncertainty
- Water insecurity directly threatens food, economic, and human security in Pakistan
ISLAMABAD: For more than six decades, the Indus Waters Treaty has stood as a rare example of sustained cooperation between rival states, shielding water governance from political volatility in South Asia.
The Treaty’s illegal and unilateral suspension by India for a year now has endangered echology of the entire South Asia, amid climate change battering. Pakistan is already amont of hostspot countries, severely affected by climate change.
A rare island of cooperation
In a region defined by recurring tensions and deep mistrust, the Treaty, brokered by the World Bank in 1960, created a predictable system for managing shared rivers.
It established clear rights, technical rules, and dispute resolution mechanisms. This prevented water issues from escalating into broader conflict.
Having no clause on unilateral exit or change, such as suspension, the Treaty inherently protects itself. The World Bank President, Ajay Banga, has already insisted on this aspect that there is no clause in the Treaty allowing any one of the parties to change its status, unilaterally. His remarks have clearly defined the Indian decisions regarding the IWT as illegal.
An international court of arbitration has also ruled in favour of the spirit of the Treaty and the stance of Pakistan, requiring India to open communication channels under the Treaty.
A dangerous departure
India’s decision to place the treaty in abeyance marks a sharp break from rules-based cooperation.
It raises serious concerns about the credibility of international agreements and the reliability of long-standing commitments.
By diluting established obligations, particularly of providing timely water and river-related data to Pakistan, the Indian move risks replacing structured engagement with unilateral discretion.
This deepens mistrust in an already fragile security environment in South Asia.
From stability to uncertainty
The Treaty, in place, reduced ambiguity by clearly defining water use and infrastructure limits. This predictability helped avoid miscalculation in a conflict-prone region.
Undermining this clarity introduces uncertainty into river governance, especially in a unique river sharing mechanism under the Treaty.
Hydrological developments may now be viewed through a strategic lens rather than a technical one. That is the rationale for Pakistan’s apex national security body declaring that any manoeuvring of water flows outside the purview of the IWT would be considered as an act of war.
Water as a strategic tool
When upstream control is exercised outside agreed rules, shared rivers risk becoming instruments of geopolitical leverage. That is what Pakistan describes as weaponising of water.
This shift transforms cooperation into competition.
In South Asia’s volatile landscape, such a shift lowers the threshold for confrontation and complicates crisis management.
Global implications
The Indus Waters Treaty has long been cited as a model for transboundary water governance. Weakening it sends a troubling global signal.
It suggests that even durable agreements can be set aside through unilateral decisions.
This risks undermining confidence in treaty-based systems across other shared river basins.
Climate stress and rising stakes
Climate change is intensifying pressure on the Indus basin. Glacier melt, erratic flows, and rising demand are increasing stress on water resources.
At such a time, stable cooperation is critical. Weakening institutional frameworks risks turning environmental stress into geopolitical instability.
Human security at risk in Pakistan
For Pakistan, a lower riparian state, predictable river flows are essential. Any disruption carries direct consequences across multiple sectors.
Unpredictable water availability disrupts agricultural cycles. This reduces crop yields and threatens food security.
Erratic flows undermine rural incomes and increase economic vulnerability. Inflationary pressures on food can intensify.
Reduced data sharing weakens flood warnings and drought planning. This increases exposure to extreme climate events.
Water variability also affects hydropower generation. This constrains energy planning and economic stability.
Public health risks rise as water quality and availability decline. Waterborne diseases can spread more easily in vulnerable communities.
A widening security challenge
Resource stress can fuel social tensions and localised conflict. It can erode community stability in already fragile regions.
Disruptions to traditional irrigation systems also weaken social cohesion and cultural continuity in river-dependent communities.
The cost of erosion
The weakening of treaty mechanisms risks reversing development gains. It undermines progress on clean water, food security, and climate resilience.
The Indus Waters Treaty is not merely a technical agreement. It is a stabilising pillar in a volatile region. Undermining it risks turning water from a shared resource into a source of conflict.
