1. Nepal is ranked as the fourth most vulnerable country in the world due to the impacts of Climate Change.
  2. A total of 3,808 glaciers and 1466 glacial lakes have been identified in Nepal. These lakes include 21 potentially dangerous lakes, out of which 6 are under very high risk. Thso Rolpa and Imja Lakes are among them (ICIMOD, 2011).
  3. The country’s average temperature is in increasing trend at the rate of about 0.04° C (Source, DHM) and the trend is much higher in the mountain region. This contributes to glacial retreat and expansion of lakes, thus possessing risk of Glacial Lake Outburst Flood (GLOF).
  4. Located at the altitude of 5010 m in the Sagarmatha National Park, Imja Lake has been mapped initially during 1960s as a small supra lake. The lake has now expanded to an area of 2 km2, 149 meter deep, holding 76 million cubic meters of water, posing a serious threat to downstream communities.
  5. Concentrated precipitation is generally high in the Churia region. However, the magnitude and frequency of flash floods have increased in recent years in the region due to impact of Climate Change.
  6. Fragile geology, heavy deforestation backed by intense rainfall largely contribute for flash floods from churia originating rivers causing huge loss of lives and properties in Terai during monsoon.
