Why in the News?

The Central Water Commission (CWC) recently released its study titled ‘Assessment of Water Resources of India, 2024.
- It estimated India’s average annual water availability from 1985 to 2023 at 2,115.95 billion cubic meters (BCM).

Key Highlights of CWC’s ‘Assessment of Water Resources of India 2024’ Report:

Total Water Availability: India’s average annual water availability between 1985 and 2023 is estimated at 2,115.95 billion cubic meters (BCM).
Top 3 Basins in (annual water availability):
- Brahmaputra Basin: 592.32 BCM
- Ganga Basin: 581.75 BCM
- Godavari Basin: 129.17 BCM
Bottom 3 Basins in (annual water availability):
- Sabarmati Basin: 9.87 BCM
- Pennar Basin: 10.42 BCM
- Mahi Basin: 13.03 BCM
Comparison to Previous Assessment (2019):
- The current figure of 2,115.95 BCM is higher than the 1,999.2 BCM estimated in 2019.
- The increase is due to the inclusion of Bhutan’s contribution to the Brahmaputra basin and Nepal’s contribution to the Ganga basin.
Per Capita Water Availability:
- Based on the 2019 study: 1,486 cubic meters for the year 2021.
- For 2024, with the new data, the per capita availability is projected to be 1,513 cubic meters (based on a population of 1.398 billion).
- Despite the increase, India remains under water stress (less than 1,700 cubic meters per capita).
Utilizable Water Resources:
- The CWC estimates utilizable surface water at 690 BCM out of the total 1,999.2 BCM.
- Smaller basins have a higher proportion of utilisable water compared to larger ones like the Brahmaputra sub-basin.

CWC was established in 1945 as the Central Waterways, Irrigation and Navigation Commission (CWINC) on the advice of Dr. B. R. Ambedkar.
