Relevance:
The Himalayas are Asia’s water tower, providing a vital regional lifeline to over two billion people through 10 main rivers that originate from the glaciers. Climate change and global warming will lead to increasing glacial melts which could destabilize these rivers by changing their stream flow. The Indus could witness more stream flow due to high glacial melt till 2050, after which the flow would start reducing due to decreasing glacial melt. The Ganga and the Brahmaputra, which are mainly monsoon-fed rivers, will also see variations, as pre-monsoon flows may decline. This will hamper agriculture that accounts for the largest share of water usage.
