DRP 18 Aug2025: Sustainable Hydropower an Oxymoron?
Analyzing a recent paper authored by 37 persons mainly from academics and hydropower related companies on “Sustainable Hydropower”, Eugene Simonov shows why the phrase is an oxymoron, a contradiction in terms. The paper fails to even refer to the most important work on hydropower projects, the report of the World Commission on Dams.

Devastation at Chasoti: Underlining the vulnerability of Chenab Basin again
Last October, we were about 15 kms from Chasoti in the Paddar valley of Jammu when we met Dular Singh jee, Priest of Machail Mata Temple, accompanied by other members of the Temple Management Board. They were on their way to Mindhal Mata Temple also on the banks of Chenab in the neighboring Pangi Valley. Theirs was a journey upstream and ours was downstream. We talked of Chenab, floods, Mindhal and Machail Mata Yatra (pilgrimage) and beautifully carved wooden temples of this region.
And today, Dular Singh jee, who is just 3kms from Chasoti, tells me in voice choked with emotion, “I have not seen such a catastrophic flashflood in my life.” The flood that started around 12 noon on Aug 14 2025, devastating Machail Mata yatra and pilgrims at Chasoti. “Mata Rani sabki raksha kare”. (May the deity protect all). He is also worried about villages like “Hangu, Hanoti, Hamori and Bhajanu Nalla”.

(Feature Image: Mud, debris following flashfloods at Dharali)
The following Indian Express report highlights some key aspects of the Oct 2020 guidelines from the National Disaster Management Authority related to disasters caused by Glacial Lake Outburst Floods (GLOF). Unfortunately, as is clear from the recent Dharali disaster most key aspects of the guidelines remain unimplemented almost five years after the Guidelines were published. Had they been implemented with any seriousness, the proportions of the Dharali disaster would have been significantly reduced.

DRP 040825: Arunachal Activists urge Centre to find dimensions of China’s Medog Dam
(Feature Image: Aerial view of the Yarlung Tsangpo’s Great Bend, Medog County)
Arunachal and other Himalayan states activists in a press conference in Delhi have rightly urged the Union Government to publicly demand from China all the features and dimensions of the Medog Dam on Yarlung Tsangpo river, their impact assessments and share the same promptly in public domain before even considering any project like the Siang Upper Multipurpose Project (SUMP). This is important since without knowing the features, dimensions, operating procedures and impact assessments, all the projections being made about the possible impacts of the projects are completely speculative and unfounded.
