Consider these facts: The NTPC, the project developer, failed to appraise that the 520 MW Tapovan Vishnugad Hydropower project, where maximum damage and deaths occurred in Chamoli Avalanche disaster that started on Feb 7, 2021 morning, is in Paraglacial influence zone. Such an appraisal would have meant a number of implications, including possibly a decision that the project is geologically unviable.
NTPC failed to take any action to save the workers even after it was known upto 10-20 minutes before the disaster struck. Something that Mangshri Devi could do to save about 25 lives, NTPC could not do.
The project had faced several disasters since 2008, but fails to put in early warning system in place. For several days post disaster, reports say that NTPC failed to share even the detailed map of the tunnel where over 30 workers were stuck. NTPC’s disaster management system showed no signs of existence throughout the disaster. Reports say that the barrage gates were closed, which if they were open, it may have helped the flow of the flood debris downstream, which in turn could have possibly meant more time and saving of more lives.

Several bridges, old and new crisscross over the rivers Mula and Mutha in Pune. Some of them are old and stately like the Lakdi Pul built over 250 years ago or the beautiful Shivaji Pul, while there are low ones like the Baba Bhide Bridge, which routinely gets submerged in the monsoons.
I try to walk across these bridges on most evenings.

More than a decade after Gangetic dolphins (platanista gangetica) was granted the status of national aquatic animal, the rare mammal species continue to face multiple threats impacting their habitat and population in Ganga rivers. Just in past one year, the year when the Prime Minister of India declared the Project Dolphin, six dolphins were found dead for unnatural reasons in three states along the Ganga. In addition to Gangetic, river dolphin were killed in three other states.

Analysis of official information shows that Big dams are not longer necessary or viable or optimal in India. Most (over 95% of India’s 5701 large dams (5264 completed and 437 under construction as per CWC’s National Register of Large Dams[i]) are built for irrigation, but most of our irrigation now comes from groundwater. In fact, about 90% of additional irrigation in last four decades has come from groundwater.

Far out in the estuary of Aghanashini, as Ismail Bhai spread out Indian Mackerel for drying, a carpet of silver spread out before us. “We fish in the river but the Bangde we catch in the sea also have their links to Aghanashini. We owe her everything”. Estuary of the modest, free-flowing Aghanashini supports around 5000 fisherolk. In the neighboring dammed Sharavathi, fish diversity plummets, so do dependent livelihoods. But rivers like Aghanashini are a rarity now.

While one can never be too sure what is the exact meaning of Chinese whispers, a thoughtful response has to take into account the available facts and the context. This report tries to take stock of available facts and context of this latest episode that started at the end of November 2020 and is still going on: China’s proposed massive hydropower project on the Great Bend of Yarlung Tsangpo River just before the river enters India as Siang, a tributary of Brahmaputra river. It also reviews the key media reports published on this issue.

The Indian Himalayan region has been facing increased cloud burst incidents for past many years. These events are followed by flash floods, landslides causing widespread damages to human lives and properties. However the forecasting, monitoring and management efforts are lagging far behind. This state wise overview attempts to understand the trend and resultant losses from such incidents during the pre-monsoon (Apr-May) southwest monsoon season (June-Sept) 2020.
SANDRP has been highlighting the issue since 2018. The details of these can be seen by exploring the hyperlink of Uttarakhand in 2018 and 2019, Himachal Pradesh 2019, Jammu and Kashmir and North East 2019.

Delhi Chief Minister Arivind Kejriiwal led govt seems to be now proposing privatisation of Delhi water supply.

IMD is happy to declare a monsoon as normal as long as total quantum of rainfall at national scale is within 4% of what is defined as normal monsoon rainfall during June 1 to Sept 30. Even if this means there is spatially or temporally or both spatially & temporally, the total rainfall or its distribution is abnormal in large parts of the country. It was good to see a national newspaper, asking question if the monsoon is normal even though it’s not temporally normal as was the case in large parts of the country this year.
The IMD normal only assures meteorological normal of national monsoon rainfall within given period. It does not assure hydrologic normal nationally or in different parts of the country, nor agricultural normal rainfall nationally or in different parts: sub divisions, states, river basins, districts, talukas/ tehsils or villages and wards. We clearly need much more realistic and nuanced definition of even meteorological Normal monsoon rainfall, which IMD needs to work on. But as far hydrological or agricultural normal rainfall is concerned, both temporally and spatially, those concerned outside IMD will need to work on.

In a rather unusual development, no less than twenty districts in contiguous areas of Madhya Pradesh, Rajasthan and Gujarat had extremely high rainfall in the 48 hours ending at 830 am on Aug 23, 2020. Three of these districts had over 250 mm rainfall in this period, four others had between 200-250 mm, six each between 150-200 and 100-150 and one between 90-100 mm. This contiguous area broadly drains Mahi river to the West, Chambal to the North, Narmada to the South and Betwa to the East. These rivers, thus are now getting heavy flows, and will continue to get for the next few days, some of it from Chambal and Betwa will also end up in Yamuna and Ganga. It reminded one of the nightmarish memories of Sept 2019 when Gandhi Sagar Dam faced existential crisis and the flood peak downstream reached upto Farakka Dam, as CWC Flood forecasting director Sharad Chandra said in a television discussion recently.
