NITI Aayog has released Composite Water Management Index (CWMI).


  • To supplement the efforts of Jal Shakti Ministry, NITI Aayog has prepared the second Round of Composite Water Management Index (CWMI 2.0).
  • Government is being proactive about water management and has created the Ministry of Jal Shakti to consolidate interrelated functions pertaining to water management.
  • The newly formed Jal Shakti Ministry under the guidance of Prime Minister Shri Narendra Modi has strived to over-bridge the water challenges by launching the Jal Shakti Abhiyan – a campaign for water conservation and water security.

Key data:

  • Thirteen of the 27 States and Union Territories have improved their water management practices from last year.
  • The 16 low-performing States collectively account for 48% of the population, 40% of agricultural produce, and 35% of economic output for India.
  • Gujarat holds on to its rank one in the reference year (2017-18), followed by Andhra Pradesh, Madhya Pradesh, Goa, Karnataka, and Tamil Nadu.
  • In North-Eastern and the Himalayan States, Himachal Pradesh has been adjudged number 1 in 2017-18 followed by Uttarakhand, Tripura, and Assam.
  • The Union Territories have first time submitted their data and Puducherry has been declared as the top ranker.
  • In terms of incremental change in index (over 2016-17 level), Haryana holds number one position in general States and Uttarakhand ranks at first position amongst North Eastern and the Himalayan States.
  • On average, 80% of the states assessed on the Index over the last three years have improved their water management scores, with an average improvement of +5.2 points.
  • Delhi, which was evaluated for the first time this year garnering the lowest score.


  • Composite Water Index is a ranking tool developed by the NITI Aayog
  • The ‘index’ aims at capturing how well States have done on groundwater and surface water restoration, implementing major and medium irrigation projects, watershed development, participatory irrigation management, on-farm water use, rural and urban water supply, and policy and governance.
  • These indicators were broken down into 28 objective indicators that include determining whether the State had policies and infrastructure in place to conserve groundwater, or its performance in providing piped water to villages.
  • For the index, States were required to fill out the necessary data on a NITI Aayog portal and this data was validated by an independent firm called IPE Global.
