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.

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.

A paper in scientific journal co-authored by Internationally renowned landslide expert Dave Petley (published on June 16 2025 at: https://doi.org/10.1016/j.enggeo.2025.108201) warns that the Joshimath landslide is moving and can threaten the under construction Tapovan Vishnugad hydropower project in Chamoli district in Uttarkhand. The paper says: “The 2023 rapid deformation at Joshimath was preceded by slow movement years ahead. Deforestation in the Joshimath region might have intensified the slope instability. Additional landslide zones were detected in Hailang, Kalpeshwar with similar pattern. Slow-moving landslides have high potential to cause often underestimated damages.”

Guadalupe River Floods: Understanding the tragedy along ‘The Most Dangerous River valley in the USA’
“This is the most dangerous river valley in the United States, we deal with floods on a regular basis.” – Kerr County judge, Rob Kelly about Guadalupe River[i], 5th July 2025
“If you live in the Guadalupe River Basin, you also live in one of the three most dangerous regions in the U.S.A. for flash floods!”[ii] – Opening Statement of “Staying safe: A Guide to Flooding in the Guadalupe River Basin[iii]” published by the Guadalupe River basin Authority
Flash Flood Watch Alert from National Weather Service received 3 hrs 21 minutes ahead of the devastating “30 feet high tsunami ball of water[1]”.
“If you do not want to be flooded, do not build or live in a floodplain”– Guadalupe-Blanco River Authority
And yet, several summer camp buildings built on not only floodplains, but on extremely dangerous floodways[iv]. more than 27 children lost to floods.

DRP 070725: Demand for Commission of Inquiry on Hydro Obsession in Himachal
(Feature Image: Flood ravaged Priyadarshini HEP in Manuni khad in Dharamshala, Kangra. Source: Social Media)
Hydropower obsession, Himalayan failure The massive hydropower push, another legacy of post-1990s liberalisation, has amplified vulnerability. Dams have mushroomed across river basins in Kinnaur, Lahaul-Spiti, Chamba, and Kullu — with scant regard for ecological thresholds. Muck from these construction sites is routinely dumped into riverbeds, narrowing channels and raising riverbeds. When the rains arrive, this loose muck turns into a lethal force, taking down everything in its path. The hydropower model — built on the assumption of perpetual revenue — has neither delivered long-term employment nor sustainable energy. Instead, it has left behind ecological scars, displaced communities, and made vast swathes of the state more disaster-prone.

In addition to severely damaging the Jiwa and Priyadarshini small hydro power projects, the ‘cloudburst’ induced flash floods on June 25, 2025 has also significantly affected the Parbati II & III projects in Sainj Valley of Kullu district in Himachal Pradesh.

DRP 16 June 2025: “Indus River older than its landscape, Himalayas”
INDUS RIVER: Stephen Alter, in his article “With the River by My Side” says about Indus River that some rivers are older than the landscape through which they pass: “Nowhere is this clash between hydrological and geological history more apparent than along the Indus, as it passed through Ladakh. This seemingly eternal river has followed its winding course since long before the Himalaya were formed, tossing and tumbling over. Boulders, stones and pebbles that the water polishes and grinds into sand. Eroded flanks of the mountains on either side of the river are scarred and twisted by tectonic forces that lifted giant slabs of rock more than eight kilometres into the clouds but failed to block the persistent flow of the Indus. Driving along the highway that runs parallel to the river, from Leh to Kargil, it feels as if the landscape is a timeless epic that the waters of the Indus have etched in stone.”

HYDRO POWER PROJECTS
Jammu & Kashmir In Kupwara district the 12 Mw Karnah in Kishan Ganga sub basin has joined the long list of HEP projects facing reoccurring damages, repeated delays and cost escalation in Himalayan states. The flash flood, landslides and cloudburst disasters in Feb and May 2025 have further damaged the project and extended its completion date.

DRP NB 260525: Opposition to large hydro as strategic projects
(Feature Image: Lahaul Spiti Ekta manch holds a protest rally against hydel projects at Udaipur in Lahaul Spiti on Friday May 23. Source: The Tribune)
Some of the most prominent reports this week are related to wide spread opposition to large hydro projects in Arunachal Pradesh, Himachal Pradesh, Kerala, among other states. Indeed, there is little sense in building large hydro projects as strategic assets as seems to be the case in Himachal Pradesh and J&K (Chenab basin) and Arunachal Pradesh (Siang basin, among others). Use of security forces to complete pre-feasibility survey when local communities are strongly against the project, as is being done in case of Siang Upper Multipurpose Project is clearly counter-productive in so many ways. In Kerala people have again gathered to oppose the destructive Athirapally Hydro projects that they have been successfully opposing since late 1990s.
