Domestic Water Issues

  • Pakistan is water-stressed — moving toward water scarcity (per capita availability dropped from ~5,000 m³ in 1947 to under 1,000 m³ now)
  • Indus Water Treaty (1960) — divides rivers: Pakistan gets Western rivers (Indus, Jhelum, Chenab), India gets Eastern rivers (Ravi, Beas, Sutlej); brokered by World Bank
  • Inter-provincial disputes — Sindh vs Punjab over water distribution from Indus; addressed (imperfectly) via 1991 Water Apportionment Accord
  • Kalabagh Dam — perennially controversial (Sindh, KP, Balochistan oppose; Punjab supports) — symbol of inter-provincial water mistrust
  • Low water storage capacity — Pakistan can store only ~30 days of water vs recommended 120+ days (Tarbela, Mangla ageing/silting)

Regional/External Hydro-Politics

  • India-Pakistan tension over IWT — India's upstream dam projects (Kishanganga, Ratle) raise Pakistani objections over treaty compliance
  • April 2025 context: India suspended/held IWT in abeyance following Pahalgam attack fallout — treated as major escalation by Pakistan (treaty had survived wars/nuclearization until then)
  • 1 September 2026 — Permanent Court of Arbitration ruled unanimously that India cannot unilaterally suspend the treaty; India rejected the ruling and abeyance continues. Full deep-dive with timeline, legal analysis, Pakistan's response and a model 20-mark answer is on the sub-page below.
  • Afghanistan — disputes over Kabul River water usage (no formal treaty exists, unlike IWT)

Compounding Factors

  • Climate change — glacial melt (Pakistan has more glaciers than anywhere outside polar regions) creating both flood risk (2022 floods) and long-term water insecurity
  • Rapid population growth & inefficient agricultural water use (flood irrigation dominant)

Policy Responses

  • National Water Policy (2018) — first unified framework
  • Push for new dams (Diamer-Bhasha, Mohmand) for storage & hydropower

Domestic Hydro-Politics — Additions

  • Cholistan canals controversy (2025): Sindh-wide protests against six new canals from the Indus; the Council of Common Interests shelved the project (April 2025) — shows the 1991 Accord's fragility.
  • IRSA disputes: Sindh alleges Punjab takes more than its share; telemetry system to measure flows has repeatedly failed.
  • Water productivity: agriculture uses over 90% of water; Pakistan produces among the lowest crop yields per unit of water.
  • Groundwater depletion in Punjab and Balochistan (Quetta's aquifer falling sharply); only a small share of wastewater is treated.
  • Afghanistan: the Taliban have announced plans to build dams on the Kunar River (2025), which could reduce Kabul River flows into Pakistan — no treaty exists.

Answer Outline (20 marks)

  1. Introduction — water as the next security frontier; per capita availability data.
  2. Domestic dimension — scarcity, storage, provincial disputes (1991 Accord, Kalabagh, canals), inefficiency.
  3. Regional dimension — IWT, Indian projects, April 2025 abeyance, September 2026 Court of Arbitration ruling; Afghanistan and the Kabul River.
  4. Climate change dimension.
  5. Consequences — food security, economy, federation, India–Pakistan conflict risk.
  6. Way forward — storage (Diamer-Bhasha, Mohmand), efficient irrigation, water pricing, groundwater regulation, IRSA reform, legal and diplomatic defence of the IWT, a treaty with Afghanistan.
  7. Conclusion.

Exam angle

  • Keep two things separate — examiners often ask them separately:
    1. internal and inter-provincial water politics
    2. India–Pakistan water politics under the IWT

1. Introduction

Water is Pakistan's lifeline: the Indus Basin feeds one of the world's largest contiguous irrigation systems and underpins agriculture, energy and human survival. Yet Pakistan is fast approaching absolute water scarcity. Its water crisis is not only about quantity; it is also about politics, between provinces at home and between states across borders. India's decision in April 2025 to hold the Indus Waters Treaty "in abeyance" turned water into a direct national security issue.

2. Scale of the Crisis

  • Per capita water availability has fallen from about 5,000 m³ in 1951 to under 1,000 m³ today, below the scarcity threshold.
  • Storage capacity is only about 30 days of river flows, compared with over 120 days recommended; Tarbela and Mangla are silting.
  • Agriculture uses over 90% of water, mostly through inefficient flood irrigation.
  • Groundwater is being depleted in Punjab and Balochistan; very little wastewater is treated.

3. Domestic Hydro-Politics

  • The 1991 Water Apportionment Accord divides Indus waters among the provinces, but disputes continue over its interpretation and measurement; IRSA's telemetry system has repeatedly failed.
  • Kalabagh Dam: supported by Punjab, opposed by Sindh, KP and Balochistan, it has become a symbol of provincial mistrust.
  • Cholistan canals (2025): mass protests in Sindh forced the Council of Common Interests to shelve the project.
  • Downstream Sindh fears shortages and seawater intrusion in the Indus delta.

4. Regional Hydro-Politics

  • India: the Indus Waters Treaty (1960) gave Pakistan the western rivers (Indus, Jhelum, Chenab). India's projects (Baglihar, Kishanganga, Ratle) were long disputed. In April 2025, after the Pahalgam attack, India held the treaty "in abeyance"; Pakistan called any stoppage an "act of war". In September 2026 the Court of Arbitration ruled unanimously that India cannot suspend the treaty unilaterally; India rejected the ruling.
  • Afghanistan: the Kabul River has no treaty; the Taliban's plans for dams on the Kunar River (2025) could reduce flows into Pakistan.
  • China: upstream of the Indus, though with limited current impact.

5. Climate Change

  • Pakistan has more glaciers than anywhere outside the polar regions.
  • Warming brings floods now (2022, 2025) and lower flows in the long run.
  • Rainfall is more erratic; heatwaves push up demand.

6. Consequences

  • Food security: lower yields and rising food import bills.
  • Economy: agriculture's 23% share of GDP is at risk; hydropower is threatened.
  • Federation: provincial disputes weaken national cohesion.
  • Regional conflict: water adds a dangerous new dimension to India–Pakistan hostility.
  • Health: unsafe water causes widespread disease.

7. Measures for Water Security

  1. Storage: complete Diamer-Bhasha and Mohmand dams; build small dams and recharge aquifers.
  2. Efficiency: drip and sprinkler irrigation, canal lining, crop diversification away from water-intensive crops.
  3. Pricing and regulation: realistic water charges; groundwater licensing.
  4. Institutional reform: strengthen IRSA with reliable telemetry; implement the National Water Policy (2018).
  5. Provincial consensus: decide projects through the CCI, with transparent data.
  6. Legal and diplomatic defence of the IWT: use the Court of Arbitration ruling, the World Bank and international forums.
  7. A water agreement with Afghanistan on the Kabul River.
  8. Climate adaptation: early warning systems, flood management, glacier monitoring.
  9. Urban water: wastewater treatment and rainwater harvesting.

8. Conclusion

Pakistan's water crisis is a crisis of scarcity, management and trust. It cannot be solved by dams alone, nor by legal victories alone. It requires efficient use at home, consensus among provinces, firm defence of Pakistan's rights under international law, and adaptation to climate change. Water security must be treated as the national security priority it has become.

Part-II — Past Subjective Questions

1. CSS 2019 Q7 — Critically analyse the key causes of delay in construction of dams in Pakistan. Give suggestions to reverse this collateral loss. (20)

Outline

  1. Introduction
  2. Pakistan's water situation
  3. Causes of delay in building dams
  4. Losses caused by the delay
  5. Suggestions
  6. Conclusion

Answer

1. Introduction

  • Pakistan can store only about 30 days of its river flow, compared with about 170 days in India and around 700 days in Egypt. No large storage dam has been completed since Tarbela in 1976.

2. Pakistan's water situation

  • Water availability per person has fallen from about 5,000 cubic metres in 1951 to below 1,000 cubic metres today.
  • The storage capacity of Tarbela and Mangla is steadily shrinking because of silt.

3. Causes of delay in building dams

  • Provincial mistrust. The Kalabagh Dam has been opposed by resolutions of the Sindh, KP and Balochistan assemblies. Sindh fears that Punjab will take more water, while KP fears flooding around Nowshera and the displacement of local people.
  • Disputes over water sharing. Disagreements over the 1991 Water Apportionment Accord and distrust of IRSA's figures make provinces suspicious of any new project.
  • Cost and financing. Large dams are very expensive; Diamer-Bhasha alone is estimated at about 14 billion dollars. The World Bank and the Asian Development Bank have been reluctant to finance projects in Gilgit-Baltistan because India disputes the territory's status.
  • Weak governance. Frequent changes of policy, slow land acquisition and corruption have stalled projects.
  • Technical and environmental issues. Many sites lie in earthquake zones, and resettlement and environmental impacts must be managed.
  • Short-term choices. From the 1994 power policy onwards, governments preferred quick-to-build thermal plants to long-term hydropower.

4. Losses caused by the delay

  • Around 29 million acre-feet of water flows into the sea each year beyond what the delta needs.
  • Crops suffer in dry years, and the lack of storage makes floods more destructive.
  • Electricity is produced from costly imported fuel instead of cheap hydropower, much of whose estimated 60,000 megawatt potential remains unused.

5. Suggestions

  • National consensus should be built through the Council of Common Interests.
  • Less controversial dams such as Diamer-Bhasha, Mohmand and Dasu, on which work began in 2018 and 2019, should be completed first.
  • The National Water Policy of 2018 should be implemented in full.
  • A reliable telemetry system should measure flows so that provinces can trust the figures.
  • Private investors and overseas Pakistanis can help finance projects, as the 2018 dam fund showed.
  • Small dams, rainwater harvesting and efficient irrigation should be promoted alongside large projects.

6. Conclusion

  • The main obstacles to building dams in Pakistan are political rather than technical. If provinces can agree on fair and transparent water sharing, dams can become a shared national project instead of a source of division.

2. CSS 2025 Q2 — How did the Indus Waters Treaty (1960) affect water distribution and relations between Pakistan and India? (20)

Outline

  1. Introduction
  2. Background
  3. Main provisions of the treaty
  4. Effect on water distribution
  5. Effect on Pakistan-India relations
  6. The crisis of 2025
  7. Evaluation
  8. Way forward
  9. Conclusion

Answer

1. Introduction

  • The Indus Waters Treaty was signed in Karachi on 19 September 1960 by Prime Minister Jawaharlal Nehru and President Ayub Khan, with the World Bank as a party. It survived three wars and many crises until India declared in April 2025 that it was holding the treaty "in abeyance".

2. Background

  • Partition left Pakistan as the lower riparian, while key headworks on the Ravi and Sutlej went to India.
  • On 1 April 1948 India stopped the flow of water into Pakistani canals, threatening crops across Punjab.
  • David Lilienthal suggested a joint solution in 1951, and the World Bank then mediated for nine years.

3. Main provisions of the treaty

  • The three eastern rivers, the Ravi, Beas and Sutlej, with about 33 million acre-feet of water, were given to India.
  • The three western rivers, the Indus, Jhelum and Chenab, with about 135 million acre-feet, were given to Pakistan. India may use them only in limited ways, including run-of-river hydropower built to strict design limits.
  • A transition period from 1960 to 1970 allowed Pakistan to build replacement works, financed by the Indus Basin Development Fund.
  • A Permanent Indus Commission was set up, with one commissioner from each country.
  • Disputes move in stages, from the Commission to a Neutral Expert and then to a Court of Arbitration.
  • Under Article XII the treaty can be changed only by a new treaty ratified by both governments, so it contains no right of unilateral withdrawal.

4. Effect on water distribution

  • Pakistan built the Mangla Dam (1967), the Tarbela Dam (1976), five barrages, a siphon and eight link canals to carry water from the western rivers to areas once fed by the eastern rivers.
  • The flow of the Ravi and Sutlej inside Pakistan dwindled, which harmed groundwater and the local environment.

5. Effect on Pakistan-India relations

  • The treaty held through the wars of 1965 and 1971 and the Kargil conflict of 1999, and the Commission met regularly for decades.
  • Disputes still arose. Salal was settled bilaterally in 1978, while Wullar Barrage remains unresolved. The Neutral Expert ruled on Baglihar in 2007, and a Court of Arbitration decided the Kishanganga case in 2013. The Ratle project is also contested.
  • India issued notices seeking to modify the treaty in 2023 and 2024.

6. The crisis of 2025

  • After the Pahalgam attack of 22 April 2025, India announced that it was holding the treaty in abeyance and stopped sharing data.
  • Pakistan declared that any attempt to stop or divert its waters would be treated as an act of war.
  • The Court of Arbitration held in June 2025 that India's announcement did not affect its jurisdiction, and on 1 September 2026 it ruled that India cannot suspend the treaty unilaterally. India has rejected these rulings.

7. Evaluation

  • For six decades the treaty gave Pakistan secure rights over most of the Indus system's water and kept water out of the two countries' wars.
  • Its weaknesses are that Pakistan gave up the eastern rivers entirely and that the treaty did not foresee climate change or India's large hydropower programme on the western rivers.

8. Way forward

  • Pakistan should rely on the treaty's legal mechanisms and the World Bank's role, and build international support for the treaty's sanctity.
  • It must strengthen its technical and legal expertise, including satellite monitoring of river flows.
  • It should build storage and use water more efficiently at home.
  • It could also propose cooperation on climate data and flood warnings within the treaty framework.

9. Conclusion

  • For sixty years the Indus Waters Treaty made water a source of stability between two hostile neighbours. If it is allowed to erode, water could become one of the most dangerous issues between two nuclear-armed states.
