The controversy of new dam construction projects on the Kabul River is no longer exactly a technical hydrology problem. In fact, it has now turned into one of the most geopolitical hot spots in the South Asian region. Pakistan regards the high-paced development of Indian-supported Afghan infrastructure along the Kabul River as a political move that could turn water into a political weapon.
However, the core of the issue is a very basic but important fact: downstream Pakistan heavily relies on the continuous supplies of the Kabul River, especially on the agricultural and hydropower supplies of Khyber Pakhtunkhwa (KP). Any form of upstream intervention that changes this stream, be it development-oriented or geopolitical, is directly impacting the water and food security of Pakistan.
In such a scenario, the increased entanglement of India in the funding of Kabul River dams is perceived by Islamabad as not benign development aid but a maneuver to rebalance the power balance in the region. Also, this concern is not just due to the size of investments that are being made in India but also due to the political environment where such investments are being done. The Kabul River is one of those rare major transboundary rivers in South Asia where there is no formal Pakistan-Afghanistan water treaty. Pakistan is exposed to this legal vacuum. It lets upstream states, in this instance Afghanistan with India as its supporter, get into storage and diversion projects without necessarily fulfilling downstream commitments. So, based on such international standards as equitable and reasonable utilization or preservation of lower-riparian rights.
The consequences of the same are not abstract to Pakistan. Flowing small on the Kabul River would strike directly into the agricultural core of KP when years of climate stress are already causing a decline in crop productivity margins. River-based irrigation systems would be severely short in periods of peak demands. The river system has hydropower units that are also a significant stabilizer in the energy provision of the region; these facilities may also have their generation capacity reduced. Moreover, they are not just inconveniences of the season, but they are structural threats to livelihood, provincial growth, and societal stability.
Notably, when the river flows reduce, farmers tend to resort to the groundwater. Yet the groundwater in Pakistan is already on its knees. Adding fuel to the fire is that upstream storage caused artificially induced scarcity, which would compel communities to extract even more, accelerating aquifer depletion and increasing the cost of pumping in the country where electricity and fuel already pose a strain to the household budget. This change creates a vicious cycle; a decrease in surface water implies that there is more groundwater consumed; an increase in groundwater extraction implies depletion; and depletion, in turn, worsens food insecurity, which Pakistan is striving so hard to prevent.
The other aspect of the new issue is internal. The Indus River System Authority (IRSA) already has a delicate inter-provincial water-sharing administration through the 1991 Water Apportionment Accord of Pakistan. In case of shrinkage of Kabul River flows, the stress may be transmitted in the whole Indus Basin. Downstream provinces could start to compete in allocations with even greater vehemence, and this undoubtedly complicated an already controversial framework and may create additional political cleavages.
Additionally, the climate change provides an additional volatility. Unpredictable downpours and unpredictable melting of the glaciers are gradually altering the river systems of Pakistan.
Pakistan has driven home multiple times that Afghanistan has no independent technical capability or financial resources to execute and administer such massive hydrological initiatives. This fact highlights how Islamabad believes that the projects do not focus on the development of Afghanistan but rather on regional politics. Megaprojects demand experience, open environmental analysis, and solid control—factors that critics do not see as well-developed or effective in the present Afghan system of governance. Even with good intentions, infrastructure may turn out to be unsustainable to the environment without proper management.
It is for this reason that Pakistan is now lobbying towards a collaborative, rules-based management of transboundary waters. Islamabad is demanding that any development on the Kabul River should be in line with the internationally accepted principles of fair and equitable use, data sharing, and harm prevention. These norms are not diplomatic slogans; they are very fundamental in avoiding the occurrence of shared rivers serving as sources of conflict.
The question is not, of course, whether Afghanistan is able to develop. It can, and it should. The question is whether transboundary development is done in a transparent, sustainable way that does not compromise the stability of a whole region. In the absence of institutional diplomacy, evidence-based negotiations, and a formal water treaty between Pakistan and Afghanistan, the margin of error, and even manipulation, is even too broad.
Kabul River is not to be a war zone, but rather a playground between neighbors. South Asia does not need more problems; it cannot extend water insecurity to an already weak land.
