Guwahati: In the first documentation of the Yarlung-Tsangpo-noon-lunch-jamuna river by the World Bank, a significant increase of 0.5 ° C in the minimum minimum winter temperature in the valley has been recorded, while the increase in extreme rainfall from the section East Basin can be more dangerous because it will increase ‘problems such as the frequency of floods and lake explosions’.
Book 378 pages, ‘River Restless: Yarlung Tsangpo-Life-Brahmaputra-Jamuna’, is about Brahmaputra as a one-river system that presents a multi-layer perspective, holistic of all river areas, which spread to four countries.

This book has a contribution of more than 90 authors.
Researchers from Tsinghua University of China, Long Di and Zhao Fanyu in their report, “For decades, the temperature changes in the basin and shows a cross-season mixture trend and in different areas.
Overall, the minimum temperature of winter is increasing and the night temperature shows the trend A very significant heating for winter and summer.
There is a significant increase of 0.5 ° C in minimum winter temperature on average above the basin.
“In and Fanyu added,” The precipitation, there is no trend of special changes in The amount of rainfall has been observed between the early period 1951-1980 and 1981-2007.
Extreme rainfall seems to decrease in the north but increases the eastern part of the basin.
The intensity of rainfall has increased slightly above the eastern part of the basin.
Therefore, there may be more Disaster problems such as the frequency of flooding and lake explosions.
“They observed that the glacier in the range of the eastern nyinquankan Mbang and mainly influenced by Indian monsoon.
“The impact of climate change in glaciers becomes clear with the majority of glaciers shrinking.
The increased temperature is one of the main causes of snow disbursement in the Tsangpo water catchment area.
The increase in the speed of snow and melts is tend to increase summer flow for decades and accelerate the expansion of glacial lake.
“University of Dhaka Qazi Kholiquzzaman Ahmad on his party reported that given the impact of climate change that worsened in the basin, regional river-based cooperation became more urgent to overcome the effects of climate change together, while at the same time handling a broad river development.
problem.
“Work and income income opportunities, especially from rural communities, in the basins are mostly still evolved around these rivers.
Millions of people continue to depend on them for water and livelihoods, including irrigation, transportation, water power plants, water for systems Other economic and economic and natural systems, “he said.
“This book reflects the diversity of human culture, which is closely related to biodiversity throughout the river ecosystem, including utilizing water and trans-border governance,” said Bibhab Kumar Talukdar, Secretary General and CEO Aarani, who contributed to this book as a co-partner ‘ Life – Biodiversity ‘in the region.
