The government website on Maha Kumbh (https://kumbh.gov.in/) has started the countdown to Mahakumbh 2025 to be held in Prayagraj from January 13 to Feb 26, 2025. It says today that it is 55 days to the beginning of Mahakumbh. But the Ganga is highly polluted in Prayagraj, and even upstream even in Uttarakhand, the state where it originates as the following reports this week say and as we all know.
The reason why the largest congregation on earth happens here every 12 years is because, as puranas say, Ganga water turns into Amrit on these holy days. So how will the Ganga water turned into Amrit at Prayagraj in 55 days?

The sudden gushing water from Adit 2 tunnel of the project near Ralli village flooded the Reckong Peo-Rampur National Highway (NH) 22 with debris in huge amount resulting in closure of highway and causing long traffic jam on both sides. The number of labourers working inside the tunnel is unknown, but reports mention they were recused safely.

This week there is some interesting news about a number of Urban rivers including Pune Rivers, Musi (Hyderabad), Chennai Rivers, Budha Dariya (Ludhiana), Gomti (Lucknow). All the news underlines some serious existential issues for Urban Rivers and raising of voices about it by local communities, governments or legal authorities.
In fact, this is part of a trend that is going on for some years. This sounds like a positive development. But unfortunately, it is not. In fact, this is sign of deteriorating condition of Urban Rivers and increasing Urban footprint on our rivers, going far beyond the boundaries of the cities. Closer examination shows that in spite of some efforts from environmental groups, local communities, some elements in the governments and the courts, the condition of our Urban Rivers is getting worse, much worse than the state of our rivers in general. More worryingly, there are almost no success stories, except some temporary respites at some places.

An interesting study reported this week reveals Big Dams are costly gambles and explains why this is so. In fact, the explanations go on to reveal that this is by design, the costs are systematically under estimated and benefits are exaggerated, so the dams fail to provide the promised benefits. So Big Dams are actually not gambles, but frauds. They get away with all this due to lack of transparency and accountability in the governance, the study reveals.
For those following the global debate on big dams over the decades know that there is nothing new here. A number of studies earlier exposed all this, including the Independent Review of the Sardar Sarovar Project instituted by the World Bank, the World Commission on Dams report, the India Country study done for WCD, among others.

A new study of available scientific publications on impact of Hydropower projects on biodiversity provides a thorough review of the subject. The review does not directly give a call not to construct more such destructive projects. But it is useful for anyone concerned about the impact of dam projects on rivers.
The study discusses the impacts of hydropower projects on both aquatic and semi-aquatic species in riverine ecosystem and cumulative impacts spatially and temporally across river basins. Dams disrupt longitudinal connectivity and act as physical barriers in upstream-downstream movement of species. Upstream of dam, there is static water environment rather than flowing river environment. In the downstream, the hydropower projects adversely affect the water flow, sediment flow, thermal regimes, affecting water quality and environmental cues for the fish movement. All these also affect the floodplains both upstream and downstream.

A number of reports listed below this week throw fresh light on functioning of global water cycle, some of the findings should be seriously worrying. The studies show how the countries across the globe have water connections that go far beyond shared rivers, lakes and seas. And how these components of global water cycles are not only changing, but are under unprecedented stress and could take the global water cycles off balance.
Another study about atmospheric rivers that provides some of the largest high intensity rainfalls show that these rivers are shifting, which can have far reaching consequences for large sub-tropical areas, polar areas and others. For understanding their implications, more studies particularly focusing on shifting El Nino and La Nina streams are required.

Despite declaring Gangetic Dolphin a National Aquatic Animal in May 2010, launching of Project Dolphin in August 2020 and recognizing October 05 as National Dolphin Day since 2022, the key species indicating river health continues to face unnatural deaths and threats from various developmental activities. This overview highlights the incidents of suspicious death of precious mammal and looming threats on its habitat along with some noteworthy steps being taken by conservationists and governments to protect the endangered species.
Continue reading “2024: Dams, Mining, Construction Damaging Gangetic Dolphin Habitats”In a pointed article this week, Sachin Tiwale rightly writes that Mumbai does not need more dams, but needs to fix the distribution of more than enough water that it gets currently. Same is the case with highly capital and energy intensive 5th stage of Cauvery Water Supply being inaugurated on Oct 16 by the Karnataka Chief Minister and Deputy CM for Bangalore, advertised through full page advertisements today (Oct 14) in newspapers in Bangalore.
What the India’s cities need is to exhaust the potential of local water resources, including rain water, local water bodies including rivers, groundwater recharge, recycle and reuse of treated sewage and also demand side measures, including fixing the distribution and reducing transmission and distribution losses. All of this needs attention through a National Urban Water Policy that will also fix the Urban Water Governance.
Continue reading “DRP 14×24: Big Dams, Long distance water will not solve Urban Water Crisis”It is increasingly clear that Large Dams across the world are facing increasing challenge due to climate change. In recent years, we have already seen serious dam disasters in Australia, Brazil, Canada, India, Kenya, Libya, Nepal, Nigeria, Poland, Spain, Sudan and USA to name just a few.
All these are related to extreme rainfall events, which are going to only increase in intensity, frequency and spread. It is interesting that hydro industry platform has come out with this report highlighting this issue this week.
For a country like India, the third large dam builder in the world, this challenge is going to be even more daunting as we have been seeing the increasing number of dams related disasters in last few years. As we remember the Teesta 3 dam disaster a year ago, the nature and dimension of this challenge becomes even starker. This is also exemplified by the fact that the dam safety panel report about this disaster is not even out in public domain. And even now new theories are being proposed about what happened during the disaster.
