The Indus Water Treaty (IWT) is a landmark water-sharing agreement between India and Pakistan. It was signed on September 19, 1960, in Karachi by then-Indian Prime Minister Jawaharlal Nehru and Pakistani President Ayub Khan.
The World Bank (International Bank for Reconstruction and Development - IBRD) played a crucial role as a mediator in facilitating this treaty. It is considered one of the most successful water-sharing agreements globally, having survived multiple conflicts between the two nations.
Key Fact: The IWT allocates the waters of the Indus River System, which comprises six rivers, between India and Pakistan.
The treaty meticulously divides the six rivers of the Indus Basin into two groups: Eastern Rivers and Western Rivers. This division ensures a clear framework for water utilization by both countries.
Core Principle: The IWT established the Permanent Indus Commission (PIC), a bilateral commission, to implement and manage the treaty. It meets regularly to resolve disputes and exchange data.
Recently, a five-member Pakistani delegation visited Jammu’s Kishtwar to inspect various power projects. This inspection was conducted on rivers covered under the Indus Water Treaty (IWT) of 1960.
Such visits are part of the treaty's provisions, allowing either country to inspect projects on the rivers allocated to the other. This ensures transparency and adherence to the treaty's design specifications for projects.
UPSC Insight: The IWT is frequently in the news due to its geopolitical significance. Questions often focus on its provisions, challenges, and its role in India-Pakistan relations (GS Paper 2).
