Two separate reports this week shows why we need to shun big dams, big hydro. The New York Times, based on several research papers have said that unstable water cycles are making big hydropower projects unreliable. This is clear this year from a number of countries, including India, China, Canada, Turkey and Ecuador among others. The report also emphasizes the loss of biodiversity, methane emissions, submergence, among other issues plaguing the hydropower projects.

Another report quoting Stanford University study says that big reservoirs cannot meet future water storage needs and we need to go for alternative, nature-based storage options. Alternative storage options like soil moisture, aquifers and local water systems. Such storage options also provide “the critical synergy between water infrastructure, climate adaptation, and agricultural resilience.”

Both are highly eminently relevant for India. When will we start adopting such options?

The river sand mining stories this week makes fascinating reading. We have stories from Andhra Pradesh, Telangana, Uttar Pradesh, Goa, Rajasthan, Madhya Pradesh and Punjab. The stories from first five states are related to judiciary. One story from Punjab is about collapse of a bridge due to illegal mining and another about how illegal sand mining is part of electoral narrative. The story from Madhya Pradesh is possibly most interesting and most indicative of the direction in which we need to go. In MP at a public hearing for sand mining project, the women of the villages, including sarpanch, have decided to save the river rather than allow unsustainable mining.

The stories from five states about judicial actions includes the one from Andhra Pradesh where the Supreme Court of India has warned the govt about contempt action. The apex court has set up committees of govt officials in Krishna and Guntur districts to stop illegal mechanized sand mining. The story from Rajasthan is about Supreme Court stopping sand mining in 1 km radius around Sariska Tiger Reserve. The stories from next two states is about the NGT action. Lastly, the story from Goa is about High Court action.

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.

DRP NB 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 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.

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.

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.
