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 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.

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.

DRP 040324: Ganga Water not fit for even bathing in Uttarakhand, UP, Bihar, W Bengal

March 4, 2024February 28, 2026 SANDRPLeave a comment

(Feature Image: A drain falling into Ganga in Varanasi. Source: Amar Ujala)

A number of reports given below from this week shows that Ganga River water is not fit for even bathing at a number of locations in Uttarakhand, Uttar Pradesh, Bihar and W Bengal. These are all official statements, mostly given in reports submitted to judicial bodies or statements by the judicial bodies.

This shows how little progress has been achieved by the government, including by the Prime Minister, central and concerned state governments including by schemes like Namami Gange and scheme of National Mission for Clean Ganga and expenditure of tens of thousands of crores of rupees. This is in spite of the promises given in the past by the Prime Minister and Union Ministers including Nitin Gadkari to clean the river by deadlines that have come and gone.

The worst part is that if we look at the trajectory of various work being done in this regard, we see no hope of any improvement in the foreseeable future unless there is major change in the way this problem is dealt with. But how will such a major change happen?

DRP 260224: Karnataka faces Drought, Farmer Distress, water scarcity

February 26, 2024February 28, 2026 SANDRP1 Comment

(Section 144 imposed near Bhadra Canals to stop illegal water lifting amid supply crisis. Representational image. TNIE)

As the two reports from media today shows, Karnataka is facing drought in 223 of 236 talukas, water scarcity and even farmer distress and suicides. The state government is aware of the situation and taking necessary measures. The situation could be similar in a number of states including Maharashtra, Telangana, Andhra Pradesh and even some of the eastern and northern states. The North Himalayan states have experienced hugely below normal snowfall in the ongoing winter. The Winter Rainfall at all India level for the period Jan 1 2024 to Feb 25 2024 is already 31% below normal.

There is role of global warming and El Nino in this and these factors are going to persist at least till the end of Indian Summer. So the governments both at centre and in states needs to be ready for the crisis.

The current Karnataka govt is awake to reality and seems to be taking the appropriate steps. Karnataka had deficit rainfall in SW Monsoon 2023.
