Lichen biomonitoring, a valuable proxy for interpreting climate change phenomenon in Himalayas: exploring causes for glacier lake outburst flood in Kedarnath region

Vertika Shukla, D. K. Upreti, Manoj Semwal


The devastating flood arising due to lake outburst flood in Kedarnath region of
Uttarakhand (16-17th June 2013) is the witness of natures fury and unprecedented
changes in the climatic condition at regional as well as global level. Apart from
geological and climatic factors, localize factors such as excessive practice of mass
tourism, vehicular movement, human activity in high altitude eco-sensitive areas
have been held responsible for increasing of temperature and destruction of
Cloudbursts are mainly trigger by regional topography that lead to the lifting of
moisture-laden winds and forming of a cumulonimbus cloud, associated with
thunderstorm and heavy precipitation. Cloudbursts are common in the western
Himalaya which may be attributed to disturbed ecological condition of Western
Himalayas because of high anthropogenic pressure and local warming (Das 2015). A
number of studies are available on monsoon cycling, western disturbance, aerosol
movement and fine carbon soot to understand the cause of flash flood.
