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.

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

May 6, 2024May 7, 2024 SANDRPLeave a comment

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.

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

April 22, 2024 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.

The Bhoj wetlands in Bhopal city is one of the oldest man-made lake in Asia. The waterbody is a fountainhead of environmental services and a designated Ramsar wetlands site. Despite this, the wetlands eco-system has been facing gradual degradation on account of growing encroachments, pollution [i] and extravagant tourist projects. Amid this, a new road project cutting through the catchment area of Bhoj wetlands and forest land around Bhopal city has raised alarm bells among concerned citizens who term its unnecessary and suggest better options as win-win solution.

The demand of NAPM to political parties going to the National elections in next couple of months to include protection of rivers and communities dependent on rivers in their manifestoes is most appropriate and urgently required.

Some key components of the demand include strengthening of decentralized river governance, role in decision making related to rivers for the fisherfolks, boats people and other river dependent communities. A draft of the People’s River Protection Bill has also been sent to the political parties. The NAPM also opposed indiscriminate construction of dams, hydro projects, embankments, barrages, river front developments, illegal sand mining, dumping of solid and liquid waste in the rivers and also interlinking of projects, all being done in the name of development, with least concern for the rivers. The draft bill also demands removal of unjust encroachments into riverbeds and floodplains. NAPM also demands continued flow in the perennial rivers by way of adequate environment flows throughout the length of the rivers from origin to its confluence with other rivers or sea.

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.

In latest example proving Delhi Development Authority’s (DDA) utter failure in protecting Yamuna River floodplains from abuse and encroachment, a large part of floodplain land has been levelled by soil dumping thus raising it by several meters at Bela Estate farm near Shashtri Park Metro Depot. As per the reports, the DDA has allotted about 19.5 ha of floodplain to forest dept for compensatory plantation. The plantation work at the site like at most of the sites on Yamuna floodplain in Delhi has suffered damages during July 2023 floods. And the levelling at the Bela Estate site is being done in the name of protecting the compensatory plantation.

The site is among few remaining floodplain patches available for spread of flood waters. The floodplain area on western bank at the location is less and already developed. Due to natural gradient, the part of floodplain on eastern side undergoes periodic floods. The patch was under several feet floodwater in July 2023. The floodplain immediately downstream the site has already been encroached by the bridge road, metro depot and buildings. Hence, raising of floodplain here would not only reduce spread of flood waters but also hamper the groundwater recharge.
