The following brilliant report on the threat of GLOFs (Glacial Lake Outburst Floods) is noteworthy from many perspectives. But possibly the most important one is to show the unknown but huge dimensions of the threat. Each of the thousands and thousands of glacial lakes in the Himalayas could pose such a threat. Alarmingly, no one can predict in most of these cases, when this threat will materialize, how big the floods it will bring and what will be the dimensions of the downstream impacts.

It is interesting that this week there are reports about growing opposition to Pump Storage Hydro Projects across the country including in Rajasthan, Karnataka, Andhra Pradesh, Madhya Pradesh (proposed project near Bargi reservoir in Narmada Valley) besides similar opposition seen earlier in Maharashtra. This should wake up the authorities and realise that the assumption of such projects being socially and environmentally benign is totally wrong.

According to a report in the National Daily, the Centre has decided to hire outside experts on fixed contracts to evaluate designs of planned hydropower projects, a move aimed at speeding up construction of several dams in the pipeline, an official said on Oct 1. The Union Govt plans to expedite construction of a slew of hydroelectric projects, especially in Jammu & Kashmir and the northeastern state of Arunachal Pradesh.

There are a number of stories this week and throughout the ongoing SW monsoon, where the key central figure is the same: Silt. This is true in case of reports about silting of dams, silting of rivers, illegal dumping of silt in rivers and dams, accumulated silt choking Punjab and Delhi rivers, and even a suggestion that what Indus Basin needs is silt management policy.
