Nearly a billion people who depend on the Indus, Ganga and Brahmaputra river basins for life and livelihood are threatened by the impact of global warming in the Himalaya-Karakoram mountains. Melting snow and glaciers will swell the rivers, but changed seasonality will affect farming, other livelihoods and the hydropower sector, while causing floods downstream, a new multinational study by researchers in Indore, Roorkee, Delhi, Bengaluru, Ahmedabad and Nepal, among others, has found. In India, the Union territories of Jammu and Kashmir and Ladakh, the states of Himachal Pradesh and Punjab and parts of northern Haryana and Rajasthan lie within the Indus River basin. Uttarakhand, Delhi, the rest of Haryana, Uttar Pradesh, Bihar, Jharkhand, West Bengal and large parts of Rajasthan and Madhya Pradesh lie in the Ganga basin. Sikkim and Arunachal Pradesh, and most of Assam, Meghalaya and Nagaland lie within the Brahmaputra basin. The affected persons, including in the megacities o ....
5 Min Read SRINAGAR, India (Thomson Reuters Foundation) - Environmentalists have urged the Indian government to review its policy of building hydropower dams in fast-warming mountain regions, after an apparent glacier collapse this week led to flooding that swept away one dam and left at least 26 people dead. The Sunday flash flood in India’s northern Uttarakhand state, triggered by what scientists said they believed was a large avalanche of glacier ice and rock, left up to 200 people missing in the Himalaya region. Rescuers this week were racing to try to free dozens of dam construction workers trapped in a tunnel by debris carried by the wave of floodwater. ....
Uttarakhand flood: Scientists highlight the need to improve monitoring of glaciers Gathering baseline data will help in understanding the hydrology, geology and climate change response of Himalayan glaciers. The site of a destroyed hydroelectric power station in Raini village of Uttarakhand. | Anshree Fadnavis/ Reuters As authorities race to rescue people trapped in Uttarakhand, following a devastating landslide-induced flash flood on February 7, scientists have called for deciphering the possibility of glacier-related hazards and enhance the capabilities of monitoring and early warning in the high mountain areas. Scientists in a review published on February 2, before the floods, stressed on improved in situ monitoring network for weather, hydrology and glacier change as a crucial requirement for predicting the future of this resource and associated hazards and their impact on regional water, energy and food security. ....
