How will the melting of Himalayan glaciers have a far-reaching impact on the water resources of India?. (UPSC IAS Mains 2020 General Studies Paper – 1)
- The Himalayan glaciers are a critical source of freshwater for India and the surrounding regions, with the majority of India’s major rivers originating in the Himalayas. The melting of these glaciers due to global warming and climate change is expected to have far-reaching impacts on India’s water resources.
- As the glaciers melt, they will initially release more water into the rivers, leading to increased water availability. However, this effect will be short-lived, and in the long term, the melting glaciers will lead to a reduction in the amount of freshwater available in the rivers.
- This reduction in freshwater availability will have significant impacts on India’s agriculture, which relies heavily on irrigation, as well as on hydropower generation and urban water supply. It is expected that the reduced water availability will lead to increased competition and conflicts over water resources, particularly in regions where water scarcity is already a significant issue.
- The Himalayan glaciers are also a critical source of freshwater for other countries in the region, including Pakistan, China, Nepal, and Bhutan. The melting of these glaciers will impact the water resources of these countries as well, which may lead to regional tensions and conflicts over water.
- The reduction in freshwater availability due to the melting of the Himalayan glaciers is expected to have significant impacts on India’s economy, particularly on the agricultural sector, which accounts for a significant portion of India’s GDP and employs a large number of people. With reduced water availability, farmers may face challenges in growing crops, which could lead to reduced agricultural productivity, food insecurity, and ultimately, economic losses.
- Furthermore, the melting of the Himalayan glaciers will also lead to changes in the timing and intensity of the monsoon rains, which are critical for agriculture and overall water availability in India. These changes in the monsoon patterns will have further impacts on the water resources of the country, leading to increased droughts and floods in different parts of the country.
- Overall, the melting of the Himalayan glaciers is expected to have far-reaching impacts on India’s water resources, and it is critical that appropriate measures are taken to mitigate the effects of this melting and to ensure the long-term sustainability of water resources in the country.
