Broad Thematic Area 1: Water Resource Management
|
|
Significance of Water Resources in the India Himalayan Region (IHR)
The Himalaya is known as "Water Tower of Asia" as perennial source of fresh water. Hence, it
plays a critical role in the major rivers of Asia. The water resources serve some of the highly
populated region of the world. However, in the current scenario available water resources are
under increasingly severe pressure from climate change and other global drivers. Climate
change alters rainfall patterns, soil moisture, humidity, glacier-mass balance and river flow, and
also causes changes to underground water sources. At the same time, floods and droughts are
rising in frequency, intensity and severity.
On the other hand, unprecedented population growth,rapid urbanization, expansion
of infrastructure, migration, land conversion and pollution translate into changes in fluxes,
pathways and stores of water, and will create further pressures on water resources that will
have a tremendous impact on the natural environment.
The Indian Himalaya Region (IHR), a part of Himalaya also has huge water
resources in its lakes, river and glaciers, however yet under threat. It may also be due to
changing rainfall pattern, protracted droughts, fluctuating temperatures, more frequent and
severe weather events, including floods, potential for hydropower generation, forest cover
degradation and other anthropogenic activities. It outlines the important of planning for
management of all the Himalaya´s water resources.
Currently under this BTA, the NMHS-PMU has sanctioned following 25 demand driven action
research studies such as rejuvenate hills springs and stream, establishing monitoring sites to
assess water quality and ecological integrity of water bodies, high-altitude meteorological
analysis, developing Decision Support System (DSSs)and water-induces disasters associate with
GLOFs and LLOFs to achieve a part of the water resource management in Himalaya region.
