Indus , Ganga, Brahmputra River Water Level to Rise by 2050: IPCC Report

According to IPCC AR6 Report, Water Level of Three Major Rivers Ganga, Indus and Brahmputra will be Rise by 2050 

As we know , Glacier melting is a big concern due to Global Warming and climate change throughout the world. Now a recent report of IPCC (Intergovernmental Panel on Climate Change ) said that there will be a water level rise in three major Asian Rivers by 2050. 


Indus , Ganga and Brahmputra Rivers , which are the major water resource for dense populated south Asian Area, will see a major increase in Runoff by 2050 and 2100.

In Indus river, water level will be rise due to increase in runoff from accelerated snow melt. While in Ganga and Brahmputra River , water level will be increased due to more precipitation. 

According to report , there will be 3 to 27 percent rise in water level in these rives. Water level rise will be 7 to 12 % for Indus river, 10 to 27 % in Ganga River and 3 to 8 % in Brahmputra River. 

The report said " The future hydro-logical extremes of the Upper Indus, Ganges and Brahmaputra river basins suggest an increase in the magnitude of extremes towards the end of the 21st century by applying RCP4.5 and 8.5 scenarios, mainly due to increase in precipitation extremes,  .

“The future of the upper Indus basin water availability is highly uncertain in the long run due to uncertainty surrounding precipitation projections" Report said. 

The Runoff in Ganga , Brahmputra and Meghna is projected to increase by 33 percent , 16 percent and 40 percent receptively due to climate change by end of the century. 

And the important thing is , The changes in runoff are larger in wet season than dry season.

According to report , Events of extreme precipitation  are expected to higher degree in the Indus than The Ganga and The Brahmputra river. 

This extreme precipitation will cause for flood in downstream regions. 

Regions of the Ganga-Brahmputra  also faces the threat of increased frequency of flood events. 

If we analyse the IPCC report , it is a very serious concern for us.Strong and necessary actions are required by Asian Countries to meet out the crisis of Global Warming and climate changes.
