The Waterscape of Asia: No Escaping from the Reality of Water
MetadataShow full item record
It is being fast established that the Himalayan hydrology will be one of the critical frontlines in the global battle against climate change and water issues. The Himalayan mountain system is of crucial importance to the river system of Asia not only in terms of influencing the monsoon but also of the glaciers that are the source of many of the great rivers. Geologists often regard all the rivers, including those originating from Tibet, collectively as the 'circum-Himalayan rivers'.The Himalayan glaciers, regarded as the 'Third Pole', contain one of the largest reservoirs of snow and ice outside the Polar regions. Major Asian river systems - the Amu Darya, Indus, Ganges, Brahmaputra, Salween, Mekong, Yangtse, Yellow and Tarim have their sources in the Himalayan glaciers contributing to almost 70 per cent of water resources. Almost 2.0 billion people stretching from Afghanistan to the Ganga-Meghna-Brahmaputra basin in South Asia to the Mekong Delta in Southeast Asia are dependent on the flows of the rivers from the glaciers of the Himalaya that includes Tibet. The impact of global warming and climate change, as studies indicate, will gradually shrink glaciers resulting in the decrease of water runoff in the long-term. In the short-term earlier water runoff from glaciers when combined with seasonal rains can result in flood conditions.
