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.”

China decommissions hundreds of dams along Red river China has claimed to have dismantled 300 dams and decommissioned more than 90 percent of small hydropower stations along the Chishui River, also known as the Red River, a key tributary of the upper Yangtze. The move is seen as one of the largest state-led efforts to restore aquatic biodiversity in Asia’s longest river, reversing decades of hydro-infrastructure development that critically endangered native fish species, including the Yangtze sturgeon, the South China Morning Post reported.

Yamuna Manthan July 2025: Is Delhi Ready for July 2023 like Yamuna Floods?

July 13 will mark two years since the Yamuna river stretch in national capital witnessed unprecedented flood spell. The river not just submerged every part of existing available floodplain by several feet but also spilled over to reclaim its lost channels. The unusual flood also breached historic 1978 flood level at Delhi railway bridge by a huge margin, setting new benchmark.

Despite disastrous flood events causing significant destruction to human lives and infrastructures for past three years, the state of Himachal Pradesh has not seen much required improvements in flood monitoring and forecast servicesby the Central Water Commission’s (CWC) to help minimize the destruction toll.

DRP 070725: Demand for Commission of Inquiry on Hydro Obsession in Himachal

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.

The SouthWest Monsoon has just set in and dam safety issues are coming up in large number of dams in Karnataka, Telangana, besides dam disasters in Himachal Pradesh. This shows how much more we need to do to assure structural and operational safety of India’s dams in changing climate.

Can Solar pumps threaten groundwater sustainability? The answer is yes. Without integrated water and energy governance India’s solar irrigation drive may worsen environmental stress, say experts. Along with the energy benefits, there are invisible consequences of solar pumps – excess water extraction and energy going waste.

Yamuna Manthan June 2025: Positive water, river stories from Yamuna basin

June 19, 2025 SANDRPLeave a comment

POSITIVE YAMUNA REPORTS

Uttar Pradesh’s Noon river runs again Jalaun farmers in Bundelkhand will not have to toil too much this season to get water for crops. They have almost revived an 81km-long local river that had dried up completely. Community members have restored the drainage basin over a 14km course of Noon river to create a funnel through which water has again entered it. The river had dried up to encroachments and poor rainfall. The revival commenced in 2021 and reached the final stage only recently, with voluntary labour contributions from thousands of local men and women. Officials said the water would start flowing through the entire course of the river in a fortnight. The river is expected to help more than 15,350 farmers.

DRP 16 June 2025: “Indus River older than its landscape, Himalayas”

June 16, 2025June 16, 2025 SANDRPLeave a comment

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.”
