State of climate services report 2021
World Meteorological Organization (WMO) released the State of Climate Services report 2021. It focuses on Terrestrial Water Storage (TWS).
Important points in report
- Water resources across the world are under tremendous pressure due to human and naturally-induced stressors.
- Extreme weather events too have been responsible for the pressure on water resources
- Terrestrial water storage dropped at a rate of 1 cm per year in 20 years (2002-2021). The biggest losses have occurred in Antarctica and Greenland.
Indian Scenario
- The TWS has been lost at a rate of at least 3 cm per year.
- India has recorded the highest loss in terrestrial water storage after Antarctica and Greenland.
- In India, per capita water availability is reducing due to an increase in population. The average annual per capita water availability has reduced to 1,545 cubic metres in 2011, from 1,816 cubic metres in 2001.
