How the exam will ask it

Prelims

  • The Kishau Multipurpose Project is located on the Tons river on the Uttarakhand-Himachal Pradesh border.
  • It is intended to provide irrigation, drinking water and hydropower benefits to six States, including the NCT of Delhi.
  • Multipurpose river valley projects are generally financed through cost-sharing arrangements between beneficiary States and the Union government.

Mains

GS Paper 1 (Geography/River Valley Projects) and GS Paper 3 (Water resources): the issue is chronic delay in inter-state river valley projects caused by difficulty in reaching cost-sharing consensus among riparian States. The fresh inter-state agreement on Kishau signals progress, but implications include long-pending irrigation, drinking water and hydropower gains for six States. The way forward lies in stronger institutional mechanisms, such as river basin authorities, to speed up inter-state consensus on such projects.
