[feb]Water scarcity likely in the Himalayan catchment if warming continues

Question 1

Study on?

Answer 1

impact of global warming and climate change

Question 2

five basins studied?

Answer 2

Sutlej, Thulo Bheri, Kali Gandaki, Dudh Kosi and Arun.

Question 3

what’s new about this study?

Answer 3

team developed a new glacier melt model and integrated it to the currently used land surface model to make the integrated model more accurate.

The currently used land surface model does not take into account glacier melt and thus could lead to serious errors in the study of north-Indian rivers

Question 4

Important observations:

Answer 4

(2031–2050), the catchment areas are more likely to face a water stress.

Snow will melt easily in a warming climate and should contribute to water flow in the region. However, the reduced snowfall will in turn reduce the amount of snow-melt.
Though glacier melt will increase initially, they will shrink in size quickly and the amount of glacier melt will also decline in the latter end of the century.
