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.

Yamuna Manthan 061124: Save River from ‘Illegal’ Sand Mining

November 7, 2024 SANDRP1 Comment

(Feature: Members of Haryana Anti Corruption Society, Yamuna Nadi Mitra Mandli, Bhartiya Kisan Sangh, Yamuna Nagar raising concerns over unabated unsustainable riverbed mining in Yamuna in Gumthala Rao, Karnal on Oct 07, 2024.)

Large scale riverbed mining has become most underestimated and least discussed threat for Yamuna rivers. While increasing pollution has turned the river stretch between Delhi and Agra ecologically dead, the rampant sand mining has been severely damaging the Yamuna eco-system in upper and lower segments.

Presently, the mining menace is quite rampant in Paonta Sahib, Yamuna Nagar, Saharanpur, Karnal, Shamili, Panipat, Sonipat, Baghpat and Ghaziabad districts along the river in upper segment. Similarly, in lower segment the main stem of river as well as its key tributaries Chambal, Sind, Betwa, Ken have been bearing the burnt of unsustainable sand mining.

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.

DRP 14×24: Big Dams, Long distance water will not solve Urban Water Crisis

October 14, 2024February 27, 2026 SANDRPLeave a comment

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 5^th 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.

DRP 07×24: Global Dam Safety Challenge in Changing Climate

October 7, 2024February 27, 2026 SANDRPLeave a comment

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.

Yamuna SW Monsoon 2024: Upper Segment Misses Flood

October 2, 2024 SANDRPLeave a comment

(Feature Image: Yamuna river at Mawi site in Kairana, UP in Sept. 2024)

After remarkable deluge in 2023, the upper segment of Yamuna river has seen no significant flood spell all through the just concluded southwest monsoon 2024. This is unusual as the river generally witnesses at least a couple of low or medium flood spells in this segment every year.

However, this year the discharges from Hathnikund Barrage (HKB) in Haryana did not cross 1 lakh cusec figure even a single time. The peak discharge from the barrage was 87,017 cusecs at 06:00 hour on 26.09.2024.

DRP 230924: Role of rivers in the birth of governments

September 23, 2024February 27, 2026 SANDRPLeave a comment

(Feature Image Source: The Economic Origins of Govt)

Interesting research published in 2023 suggests that archaeologists and economists are now learning that dynamic, shifting rivers also created conditions that triggered people to develop some of the first organized govts on the planet.

In the research published in The American Economic Review Robert Allen and two co-authors found that Agriculture and large settlements emerged alongside rivers because they could tap into the gifts of rivers: close access to water and fertile soil. But rivers can move and take those gifts away. So, society developed organized govts to work collectively to regain their access to those gifts.

Like every monsoon, a number of cities have faced catastrophic floods in SW monsoon this year. Vadodara and Vijaywada have got the media attention more than any other city for urban floods this year. In both cases a number of factors are common: role of upstream dams, encroachment on water bodies including rivers, lakes, streams, role of illegal sand mining particularly in Vijaywada, not having learnt any lessons from past flood disasters.

It is interesting to see Andhra Pradesh CM hinting at bringing HYDRAA like enforcement institution to remove encroachments on Budameru and other water bodies. Considering the nature of his politics and track record, it is doubtful if this NDA CM will take such a bold step, but it is certainly worthy of consideration for almost all urban areas in India.

DRP 090924: Question marks over Yettinahole should not be buried under money spent

September 9, 2024February 27, 2026 SANDRPLeave a comment

(Feature Image: File photo of Yettinahole Project. Source: Daijiworld)

The Yettinahole project has seen protests and question marks right from the time when the project was proposed, none of them have been convincingly answered. As the Karnataka Chief Minister and his deputy commissioned a small part of it, those question marks remain as relevant today, including its hydrological viability, environmental impact assessments and sustainability, with hugely weakening of the western ghats by such major interventions without any credible impact assessments. (see: https://sandrp.in/2013/09/18/yettinahole-diversion-an-imprudent-rs-100-billion-proposition/)

It is good to see CWC and MoEF have also raised some questions and asked report even at this stage. One however expects CWC to raise such questions much earlier in the project cycle and before the project becomes fait accomplice. Else, it seems more like politicking. MoEF could have raised issues of violations before the violations happened on ground and should have refused to provide piece meal forest clearances as it has alleged.
