In news: Recently, the NITI Aayog released the Composite Water Management Index (CWMI) 2.0 to assess and improve the performance in efficient management of water resources. 

About CWMI:

  1. The Composite Water Management Index report is a step in a direction that aims to create awareness among people and governments about the realities of the water crisis in the country.
  2. It would provide useful information for the states and concerned Central ministries and departments.
  3. It will help in enabling them to formulate and implement suitable strategies for better management of water resources.
  4. NITI Aayog has ranked all states in the index on the composite water management, comprising 9 broad sectors with 28 different indicators covering various aspects of groundwater, restoration of water bodies, irrigation, farm practices, drinking water, policy and governance.
  5. States and Union Territories (UTs) have been scored on the Index are  divided into three categories: non-Himalayan states, North-Eastern and Himalayan states, and Union Territories (UTs). 

Key highlights of the report:

  • A majority of Indian states are demonstrating progress - 80% of the states (19 out of 24) have shown improvement in their water management scores over the last three years. 
  • High-performing states continue to lead on the Index- such as Gujarat and Andhra Pradesh. 
  • The low-performing states bear the largest burden of national population and economic production. The 16 low-performing states collectively account for 48% of the population, 40% of agricultural produce, and 35% of economic output for India.
  • Restoration of water bodies: Overall performance on surface water restoration slipped during FY 17-18 compared to FY 16-17, due to the decline in the performance of Maharashtra, Chhattisgarh, and Nagaland. 
  • Sustainable on-farm water use practices: states have failed to show any significant improvement in on-farm water use efficiency.
  • Urban water supply and sanitation: water access remains high on average; significant gaps exist in wastewater treatment. 
  • Participatory irrigation practices: Overall, performance declined marginally in the last three years. Actual implementation of WUA (Water User Association) responsibilities (such as involvement in O&M of irrigation assets) remains low.
  • Improvement is piecemeal: Improvement demonstrated by states and UTs is not consistent across themes, and average state performance declined on four themes. 
  • low-performing states bear the largest burden of national population and economic production.
  • Rural drinking water: Overall scores declined in FY 17-18 from a low base in FY 16-17 (less than 50% of the total achievable score), largely due to poor performance on the new service delivery indicators introduced under the theme this year.
  • Source augmentation (Groundwater): Overall, states have displayed improvement in recharge of their groundwater resources between FY 15-16 and FY 17-18, but the median continues to remain below 50% of the total achievable score.
