Indus Waters Treaty Between India and Pakistan: Origins,
Framework, Issues, and Outlook
Introduction: One of the Most Unique Treaties
The Indus Waters Treaty (IWT) is one of the most unique agreements on transboundary water management. It was signed between India and Pakistan in 1960, under the supervision of the World Bank.
Although there were multiple political and military conflicts between the two countries, the Indus Waters Treaty continued to exist for more than half a century. Thus, the document is recognized today as one of the most successful agreements of its kind.
The IWT establishes a precise water sharing agreement of the Indus River System. It also covers issues of irrigation, hydropower, and water security for both nations. This article will provide an overview of the Indus Waters Treaty’s history, provisions, water sharing, disputes, and significance.
Indus River System Background
According to the World Bank, the Indus River Basin covers an area of 1,120,000 km² in China, India, Pakistan, and Afghanistan. The river system is critical to the livelihood of millions of people downstream. It provides water for agricultural irrigation, municipal water supply, and electricity production via hydropower.
Prior to the partition of British India and Pakistan in 1947, the irrigation structures along the Indus River were unified. The creation of national borders meant that India and Pakistan had to share control of water streams, irrigation dams, and canals. The first dispute occurred in April 1948, when India cut off water supplies to Pakistani irrigation systems.
The negotiations started in 1952, with the involvement of the World Bank, and lasted for eight years. They led to the creation of the Indus Waters Treaty (IWT), which was signed on 19 September 1960.
Indus Waters Treaty: Key Provisions and Signatories
The IWT was signed in Karachi by Prime Minister Jawaharlal Nehru of India and President Mohammad Ayub Khan of Pakistan, with a participation of World Bank’s representative, W. A. B. Iliff.
Among other things, the treaty determined that the six rivers of the Indus River System would be divided into two groups. One group of rivers (the Eastern Rivers) would be allocated to India, while the other group (the Western Rivers) would be allocated to Pakistan.
Allocated Rivers to India
The Eastern Rivers include the Ravi, Beas, and Sutlej Rivers. According to the IWT, India has the right to use all waters of these rivers for agricultural, domestic, and industrial purposes.
Indian Rights on the Western Rivers
Although the Indus, Jhelum, and Chenab Rivers were allocated to Pakistan, the IWT granted India some rights on these rivers.
For instance, India has the right to use waters of the Western Rivers for drinking water, navigation, agricultural, power generation, and other non-consumptive purposes. Large-scale storage projects on the western rivers are prohibited, as they may interfere with Pakistan’s water needs.
Water Distribution under the IWT
According to the Indus Waters Treaty, India has a 20% share of water from the Eastern Rivers. On the other hand, Pakistan has an 80% share of water from the Western Rivers.
The table below summarizes the distribution of the Indus River waters under the IWT.
River Group Allocated to Country Approx. Share of Water
Eastern Rivers (Ravi, Beas, Sutlej) India Around 20%
Western Rivers (Indus, Jhelum, Chenab) Pakistan Around 80%
Although allocated to India, the Eastern Rivers are vital for Pakistan’s water supply and agriculture. For instance, the Ravi, Beas, and Sutlej Rivers are critical sources of irrigation and drinking water for millions of Pakistanis. Moreover, these rivers provide hydropower and ecosystem benefits to Pakistan. Similarly, the Western Rivers are critical for the survival of millions of Indians.
Permanent Indus Commission: Dispute Resolution Mechanism
The Indus Waters Treaty requires both countries to establish a bilateral commission for technical matters. It is known as the Permanent Indus Commission (PIC). Under the terms of the treaty, India and Pakistan appoint Commissioners to serve on the PIC.
The responsibilities of the PIC include exchanging information on hydrological conditions, inspecting dams and water structures, discussing technical issues, and deliberating ways to resolve disputes. In spite of political tensions, the PIC has always been a platform for effective communication between India and Pakistan.
Disputes under the Indus Waters Treaty
There have been several disputes under the Indus Waters Treaty between India and Pakistan. They include the Baglihar Hydropower Project dispute, the Kishanganga Hydropower Project dispute, and the Ratle Hydropower Project dispute.
Each of the disputes involved disagreements over technical specifications or water usage terms. The treaty has a dispute resolution mechanism which is based on three stages of conflict resolution. As a result, the disagreements rarely evolved into full-scale political or military confrontations.
Importance of the Indus Waters Treaty
The Indus Waters Treaty is important for several reasons, including the following:
- It provides a dispute resolution mechanism for India-Pakistan water disagreements.
- It ensures that the Indus River provides water for irrigation and other uses in both countries.
- It promotes technical cooperation and communication between Pakistan and India.
- It reduces tensions and risks of military action between Pakistan and India.
- It facilitates sustainable use and management of water resources in the Indus River Basin.
- It establishes a legal regime for water usage in the Indus River Basin.
Challenges Facing the Indus River System
The Indus Waters Treaty has facilitated mutual water usage and cooperation between India and Pakistan. Nevertheless, several challenges threaten the future of the Indus River System. They may affect the ability of the IWT to sustain agricultural, municipal, and environmental water needs. Some of the challenges include the following:
Climate Change and Variability
The effects of climate change are projected to be severe in the Indus River Basin, Himalayas, and the surrounding regions. These include glacier melt, shifts in seasonal weather patterns, extreme precipitation events, and rising temperatures. Consequently, streamflows in the Indus River Basin may become unpredictable and unseasonal. New measures will be necessary to adapt to these impacts.
Population Growth
Both Pakistan and India are experiencing high population growth rates. The expanding population will lead to increased water demands for agricultural irrigation, municipal water supply, and hydropower.
Aging Water Infrastructure
Much of the existing water infrastructure in Pakistan and India is aging and requires upgrades. This is critical for ensuring reliable water supplies and hydropower generation in the future.
Environmental Conservation and Restoration
The conservation and restoration of the Indus River Basin ecosystems are crucial for long-term water security. This is a key concern for both India and Pakistan. It includes measures to maintain environmental flows, restore wetlands, and conserve biodiversity in the river basin.
Future of the Indus Basin under the IWT: Emerging Opportunities
The future of the Indus Basin water resources depends on the ability of Pakistan and India to cooperate under the IWT. There is an opportunity to strengthen this cooperation by engaging in collaborative initiatives, including the following:
Sharing of Hydrological Data and Flood Forecasting
India and Pakistan can exchange hydrological data and invest in flood forecasting technologies and early warning systems.
Climate Change Adaptation and Management
Both countries can collaborate on climate change adaptation and management strategies for the Indus River Basin.
Joint Research on River Basin Hydrology and Ecology
India and Pakistan can conduct joint research on various aspects of the Indus River Basin, including hydrology, ecology, and watershed management.
