Impact of Climate Change on Water Resources

Nepal has observed dramatic change in water resources which are often linked with the climate change. Nepal has more than hundred rivers that were originated from the Himalayas. The flow in those rivers is reported to decrease in the recent days.  Likewise, rate of retreating glacier are increasing and formation of glacier lakes are increasing. All these facts are reported to have direct relation with the climate change. In Nepal more than 23 glacier lakes are in the state of potential dangerous. They may burst any time. The enlargement of such glacier lakes are increasing day by day. Nepal has already experience the Glacier Lake Outburst Flood (GLOF) in 1885.  Dig Cho Lake was burst in 1985 that has caused several damages. This is taken as the cause of increase in temperature.

 Underground water levels are also decreasing in recent days. This has been taken as an effect of urbanization and over extracting of ground water and has major role of increasing temperature.
