As per this Reuters report based on official information and statements, in June 2024 India will face the biggest peak hour power shortfall in 14 years, mainly due to the slump in hydropower generation. This is the result of not only pushing hydropower projects over the decades, but also not taking any steps to optimize peaking power generation from existing hydro or doing anything worthwhile to manage peak load. India’s hydropower generation had steepest fall in four decades in the year ending on March 31 2024, which was another reason not on rely on unreliable hydropower projects. The regular and frequent disasters that we see connected with hydropower projects in almost every month and more frequently in monsoons should be another reason in this regard.

The massive leakages in penstock of Lambadug Hydro Electric Project (HEP) on May 10 2024 morning have caused extensive damages in Multhan market area of Kangra district in Himachal Pradesh. The sudden leakages turning into a flash flood spell occurred around 08:00 am on May 10, 2024. As per reports the deluge containing mud and debris spread over 400 meter of market and invaded about 50 homes, 80 shops apart from damaging cash crops over 6 acres farming land.

The incident created panic situation for 150 families living in the area. Several residents had to run to save their lives. The project and administration officials remained unavailable to control the situation for hours. With no help in site, the local people had to divert the gushing currents towards Lambadug river to prevent further damages to their homes and properties.

Tawi Barrage & Riverfront Projects in Jammu destroying river, inviting disaster

(Feature Image: a picture of Tawi Riverfront and Real Estate Development uploaded on Jammu Smart City website)

Tawi Riverfront Development (RFD) project in Jammu symbolizes the fallacy of most of the RFD projects in India. The city owes its historical relevance, cultural legacy and gradual prosperity to the river. But in return the Tawi has been witnessing typical urban river problems of gradual decline in flows, continual rise in solid and liquid waste pollution, encroachments and riverbed mining. And as is the case with most of urban rivers, instead of taking effective measures to address the existing threats, the government here has been pumping crores of rupees into an artificial lake and RFD project for over past one and half decade in a non-transparent and questionable manner.

DRP 060524: Study on dam induced river flooding in Peninsular India

May 6, 2024February 28, 2026 SANDRPLeave a comment

(Feature Image: (a) Locations of streamflow gauges with catchment boundaries in six major river basins of Peninsular India, (b) elevation map and mean annual maximum runoff rate (streamflow per unit catchment area), (c) Aridity Index (AI) and (d) Baseflow Index (BFI). The maps in first row are prepared in QGIS (Version 2.14.0 ‘Essen’ (2016), URL: http://qgis.org) and the maps in second row are generated using R (Version 4.2.2 (2022), URL: https://www.R-project.org/). Source: Baseflow significantly contributes to river floods in Peninsular India )

A recently published study, see details given below throws light on the role of groundwater contribution to baseflow in rivers and their flooding in Peninsular India’s river like Narmada, Tapi, Mahanadi, Godavari, Krishna and Cauvery. The found that while baseflow contributes more to river flows, its share in the flood event flow magnitude decreases as surface runoff accounts for a larger proportion of flood discharge on the day of the flood.

Most significant are the findings related to dam induced flood that SANDRP has been writing for long and the finding corroborate exactly what SANDRP has been saying: Sudden releases of water from a dam can raise river levels during extreme rainfall events, especially when the dam is nearly full. The impact of sudden floods is more destructive because people living in nearby areas are often unprepared. Without a dam, floodwaters rise slowly over time, allowing people to take preventive measures. However, sudden floods caused by dam releases offer little or no time to prepare, increasing the risks associated with dam-induced flood hazards. Furthermore, the construction of dams alters the natural regime of rivers, leading to changes in sediment transport and erosion patterns. These changes can heighten the risk of flooding downstream from a dam.

Yamuna Manthan 0524: SC Stays 4 NBWL cleared Dams in Kalesar Wildlife Sanctuary

(Feature Image: Google Earth Image showing location of 6 proposed dams in Kalesar national park area by Haryana government)

In a welcome judicial intervention, the Supreme Court on April 24, 2024 has stayed building of four dams inside Kalesar National Park in Yamuna Nagar district of Haryana. Issuing notices to Centre and Haryana governments, the apex court noted that the dams namely Chikan, Kansli, Khillanwala and Ambawali would not achieve the intended purposes and would prove detrimental to wildlife, biota and eco-system of the National Park.

Disappointingly the National Board of Wildlife (NBWL) had approved the dams ignoring the Wildlife Institute of India (WII) report warning about adverse impacts of these dams on the terrestrial as well as aquatic biodiversity in the protected area. As per the WII report, the Irrigation Department, Haryana had planned building of six dams costing about Rs. 125 cr. on streams feeding Pathrala river in the national park.

DRP 290424: Why is Climate Change not major election issue?

World’s largest democratic exercise is now ongoing in India to elect the members of India’s Lok Sabha. Over 97 crores are eligible to vote in these elections. One of the biggest factors that is adversely affecting people across India currently is Climate Change. It is affecting almost every aspect of life and the adverse impacts are only increasing with every passing year. This is man-made disaster basically happening due to anthropogenic reasons, affecting air, water, climate, food, health, livelihoods, disasters and so on, affecting everyone. Currently, India is also a major contributor to the climate change causing green-house gas emissions, even though historically, the developed countries have contributed much more.

More importantly, the development options that the elected government choose will decide how the people will be impacted by climate change. The government has large number of options for pathways to development. Considering all this, one expected that climate change responses will be a major issue in these elections. But that is clearly not the case. BJP and Congress, two of the biggest parties fighting the elections, have mentioned climate change in their manifestos, but neither has dealt with this important issue with the detail and seriousness required. Nor are any of them making climate change a major election issue. One expects the ruling party to at least respond in greater detail and seriousness to this issue, but that is not the case.

DRP 220424: International Energy Agency accepts high-cost high risk hydro is no longer High Priority

April 22, 2024February 28, 2026 SANDRPLeave a comment

The International Energy Agency (IEA) has accepted in its latest World Energy Investment Special Report titled “Reducing the Cost of Capital: Strategies to unlock clean energy investment in emerging and developing economies” has candidly accepted that hydropower (excluding pump storage) is no longer the high-priority sector.

Among the challenges hydropower faces, according to IEA, include long permitting time necessary considering the high and complex impacts of hydropower projects amd delays during construction. IEA figures show that the capacity of Chinese developed hydropower projects that had high proportion of installed hydropower capacity globally in any year for decades, was the lowest in 2023 since 2014. The report accepts that high cost of capital with high interest rates can have a major impact on Cost of electricity, affecting competitiveness of the hydropower projects.

On March 21, 2024, a case related to the Grean Indian Bustard, a critically endangered bird – numbering less than 150 individuals – has led the Supreme Court of India to expand citizens’ constitutional right to life and equality to include the right to be free from the adverse impact of climate change. The PIL filed by M.K. Ranjitsinh asked to protect the GIB from extinction. In 2021, in this PIL, the Supreme Court had passed directions restricting and regulating power lines and renewable energy projects in an area of 99,000 sq km in Rajasthan and Gujarat.

The Supreme Court’s latest order modified directions passed in the earlier judgment. Chief Justice D.Y. Chandrachud – writing for the 3-judge bench including Justices J.B. Pardiwala and Manoj Mishra – has expanded the contours of environmental jurisprudence: from the oft-repeated polluter pay principle–precautionary principle–public trust doctrine to the larger arena of climate justice, environmental inequity and gender justice. However, in the process, the protection the SC gave through earlier order has been withdrawn.

Sand Mining

Why Existing Rules, Regulations Fail to Deter Illegal Sand Miners of Ken River?

April 6, 2024May 1, 2024 SANDRPLeave a comment

(Feature Image: Screenshot of Bundeli Junction video report dated Nov. 19, 2023 on large scale mechanized, instream sand mining in Ken river in Banda district. )

Ken is lifeline of Bundelkhand and among key tributaries of Lower Yamuna basin. The river is relatively clean and free of industrial pollution. However, its existence is under threat due to catchment degradation and the proposed Ken-Betwa interlinking proposal. Apart from this, the river eco-system and dependent people have been at receiving end of large scale mechanized and unsustainable, mostly illegal mining practices for the past many years.

Some recent short video clips, media reports and satellite images have again revealed that sand miners continue to indulge in river destructive mining activities in government approved mine sites in three districts of two states namely Panna and Chhatarpur districts of Madhya Pradesh and in Banda district of Uttar Pradesh. The miners here have blatantly violated the existing mining rules, MoEF guidelines and NGT orders while the respective regulatory agencies have miserably failed to enforce the laws and ensure compliance.
