This paper reviews the literature on the
potential biophysical and economic impacts of climate change
in the Himalayas. Existing observations indicate that the
temperature is rising at a higher rate in Nepal and Chinese
regions of the Himalayas compared with rest of the
Himalayas. A declining trend of monsoon in the western
Indian Himalayas and an increasing trend in the eastern
Indian Himalayas have been observed, whereas increasing
precipitation and stream flow in many parts of Tibetan
Plateau are noted. Glaciers in both the eastern and western
Himalayas are mostly retreating, but the majority of the
glaciers in Karakorum are either stable or advancing slowly.
Expansion of glacier lakes is reported, with the highest
rate in Nepal and Bhutan. Most literature predicts increases
in temperature and monsoon precipitations and decreases in
winter precipitations in the future thereby leading to
monsoon flooding and increased sediments in stream flow.
Available hydrological simulations indicate reduced rainfall
and shrinkage of glacier thereby leading to shortage of
water supply for power generation and irrigation in winter
particularly in highly glaciated basins. Projected economic
impacts of glacial lake outburst floods can be substantial
on the developed river basin with infrastructures and
population centers. However, there is a clear gap in
knowledge of economic impacts of climate change in the Himalayas.
