Opening
Indian Himalayas region is characterized by a diverse nature of glacial landforms & this has ultimate bearing upon local ecosystem & human activities :
Body · points
Glacial landforms
(1) Col : A high peak (Ex: Indira col of Siachen)
(2) Arete cliff like progression
(3) Tarn lake At the basement
(4) Glacial lake
→ formed by deposition sediments of nearby places. → when seismicity occurs, GLOF (floods) may occur.
(5) Floodwash Plain → Area left behind after a glacier glided through the path
(6) Fjords where glaciers directly meet a water body → highly picturesque
(7) Eskers, longitudinal valleys, inundational channels, etc.
Impact on local Ecosystems
(1) Culture → Ex: mt. kailash (Arete, col) → Ex: mansarovar lake (Glacial lake) → Pure Ganga, etc. (Badrinath, etc.)
(2) Ecology 2.1 → Provision of fresh water 2.2 → Support to biodiversity (snow leopard) 2.3 → Flora diversity
(3) Patterns of settlements: → Less settlements in valley due to Anabatic & Catabatic flows.
Impact on human activities
(1) Recreation 1.1 Skis during snowfalls of Winters 1.2 Tourism to Himalayas to break out from city monotonicity
(2) Livelihood 2.1 Rampant construction of Hotels, transport Infra, etc. 2.2 Hydroelectricity generation due to rapid flow of Himalayan Rivers.
Close · a way forward
However, Mishra Committee has recommended to slow down the unchecked pace of developmnt. Separate EIA for Himalayas is desirable.
