 Indus River System

Map: India

Current relevance:

i.            India has rejected the latest pronouncement of the Court of Arbitration at The Hague concerning the Indus Waters Treaty (IWT) and the Ratle Hydroelectric Project, maintaining that it does not recognise the arbitral body's jurisdiction.

ii.            The wider dispute concerns the design of India's Kishenganga and Ratle hydroelectric projects. India's official MEA annual report records that Ratle is under construction in Jammu & Kashmir and that India has participated in the separate Neutral Expert process concerning technical design questions.


Continent:

The Indus River system is located in Asia, primarily across South Asia, with its upper reaches extending into the Tibetan Plateau.

Important Places:

           i.            Ratle Hydroelectric Project: Located on the Chenab River in Jammu & Kashmir and central to the current dispute.

         ii.            Kishenganga Hydroelectric Project: Located on the Kishenganga River, a tributary of the Jhelum system, in Jammu & Kashmir.

       iii.            The Hague, Netherlands: Seat associated with the arbitration proceedings referred to in the present dispute.

      iv.            Karachi: The Indus Waters Treaty was signed at Karachi on 19 September 1960 by India and Pakistan, with the World Bank performing the role specified under the Treaty.

Six Rivers under the Indus Waters Treaty:

The Treaty defines Ravi, Beas and Sutlej as the Eastern Rivers and Indus, Jhelum and Chenab as the Western Rivers. Under its original allocation framework, the Eastern Rivers were made available for India's unrestricted use subject to Treaty provisions, while Pakistan received unrestricted use of the Western Rivers subject to specified Indian uses.

Indus River — Course:

           i.            The Indus originates in the Tibetan Plateau region, enters Ladakh, then flows through Pakistan before ultimately emptying into the Arabian Sea.

         ii.            Its major tributary system includes the Jhelum, Chenab, Ravi, Beas and Sutlej. The World Bank describes the Indus system as the Indus plus these five principal tributaries.

Countries Associated with the Basin:

           i.            The most important countries to mark are India, Pakistan and China.

         ii.            The key bilateral relationship is India–Pakistan, since these are the two parties to the Indus Waters Treaty, 1960

Significance:

           i.            Water security: The Indus system is fundamental to irrigation, agriculture and water supply, particularly across northwestern India and Pakistan.

         ii.            Hydropower: The Western Rivers possess substantial hydropower potential. The Treaty expressly provides for certain Indian hydroelectric uses on these rivers subject to its provisions.

       iii.            Transboundary importance: Partition transformed what had been an internal river-management issue into an international water-sharing question between India and Pakistan.

      iv.            Treaty significance: Signed in 1960 after about nine years of negotiations, the IWT established a framework for allocation, cooperation, information exchange and dispute-resolution mechanisms concerning the Indus system.

        v.            Strategic relevance: Projects such as Ratle and Kishenganga have made hydropower design and Treaty interpretation important elements of India–Pakistan water relations.
