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 060524: Study on dam induced river flooding in Peninsular India

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.

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.

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 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.

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.

DRP 010424: As Krishna basin faces drought and scarcity, water diverted from the basin to Konkan

Large parts of South India, including Maharashtra are facing depleted reservoir levels with the beginning of summer and water scarcity. However, the Krishna Bheema basin, the second largest basin of peninsular India, is diverting water to outside the basin to Konkan. The Krishna Bheema basin has the largest live storages of Maharashtra in Koyna dam (1347.5 MCM) and Tata dams (617.67 MCM), but the water in those storages won’t be available to the drought hit residents of Krishna basin in water scarce Maharashtra, Karnataka, Telangana and Andhra Pradesh.

This is because Koyna and Tata dams divert the water from Krishna Bheema basins to Konkan for power generation. Even in March, according to Maharashtra Load Dispatch Centre, Koyna had generated 128.87 Million Units (MU) of power and Tata Dams had generated 130.47 MU, both by March 30. This implies diversion of millions of Cubic meters of water from Koyna and Tata Dams during March 2024, which mostly gone down from Konkan to Arabian sea.

The Electoral bonds details now in public domain, thanks to the Supreme Court of India orders, has once again highlighted the political economy of large dams, hydropower projects and irrigation projects. It has once again confirmed what was publicly known that such large water projects involve kickbacks to political parties.

The details so far available involves companies like Megha Engineering, Rithwick Projects Pvt Ltd, Navayuga Engineering Company Ltd, among others. The projects so far that seems to be involved include Polavaram Dam, Kaleshwaram Lift Irrigation Project, Sunni Dam and Hydro projects, Kundah Pump Storage Hydropower project in Tamil Nadu and Silkyara Tunnel, almost all of them also involved in some kind of disaster or other.
