One of the heartening development this week is from Kerala, where Chalakudy river community held a satyagraha to demand proper integrated dam management plan in the Chalakudy River basin to minimize flood risks. It is rather rare that communities come out for such a demand. It was also great to see that the satyagraha was supported by Chalakudy Puzha Samrakshan Samiti, Chalakudy municipal chairman and also environmentalists.

The satyagraha in fact had specific demand for each of the dams included in the Paramibikulam Aliyar Project, including in Kerala and upstream Tamil Nadu. We hope the Kerala government positively responds to these demands at the earliest.

We are in the thick of monsoon and also flood season. To manage floods, key inputs are accurate forecasts and prompt, accurate, location, river specific rainfall. India Meteorological department has a key role to play in all these aspects that can help us manage floods, as a very pointed Editorial in Indian Express stated in the context of Assam Chief Minister Himanta Biswa Sarma’s flip flops.

The edit referred to the 2021 parliamentary panel report that asked the Centre to set up modern weather stations in the upstream catchment of the Northeast’s rivers and install sirens to alert people downstream of floods. North East and rest of the country continues to lack such systems.

The news this week that India and Bangladesh have agreed for India to help Bangladesh conserve the Teesta River that flows from India to Bangladesh. We hope this development is taken to its logical conclusion soon in terms of implementation of the project as soon as possible. This has the potential to not only two nations working together on conservation and rejuvenation of the Teesta River, but also possibly other 53 shared rivers. However, it would have been better if the W Bengal government would have been briefed, taken into confidence and involved in the discussions. History tells us that the cooperation efforts do not succeed without the involvement of all the stakeholders.

The formation of Joint Technical Committee to initiate discussions for the renewal of the Ganges Water Sharing treaty 1996 that will expire in 2026. One hopes that all these happen with a benevolent disposition from India as this has the potential of creating a much stronger bond between the two countries. A good example is the 1996 Ganga treaty that was also signed with a benevolent disposition. This move can also help strengthen the relations across South Asia as both Nepal and Bhutan are hoping to export hydro-electricity to Bangladesh via India.

The news this week that SSNNL has decided to operate the 1200 MW River Bed Power House and the 250 MW Canal Head Power house to reduce the water level in Dam from 122.28 meters on June 14 to around 115 m before the monsoon inflows start, in anticipation of the above average rainfall anticipated during SW Monsoon 2024 is welcome. One hopes this is sign of SSNNL, Gujarat Government and the Narmada Control Authority have learnt some lessons after the avoidable flood disasters brought by SSP in 2023 and earlier in 2019 and 2020, as revealed by SANDRP’s analysis in each of these years.

One hopes this is not just one-off ad-hoc decisions, but part of a systemic change. This will require an integrated basin level reservoir operation policy including all the major dams of the Narmada Valley and put it out in public domain along with clearly defined Standard Operating Procedure, and names of the responsible officials for each of such major dam in the basin. The Central Water Commission will also need to be held accountable for its flood forecasting including the 7-day advance forecasts.

DRP NB 100624: Global research suggests: shun big dams, big hydro

June 10, 2024 SANDRPLeave a comment

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?

As the Hindustan Times Editorial today (June 3, 2024) has rightly underlined, a major challenge before the newly elected state governments in Sikkim and Arunachal Pradesh is to urgently review the existing, under construction and planned mega hydropower projects in the fragile Himalayan ecology in these border states.

These states are inherently vulnerable to large kinds of disasters including landslides, earthquakes, erosion, floods, GLOFs and also multi hazard disasters. These inherent vulnerabilities are already hugely increased under climate crisis. The large hydropower projects being taken up here are acting as force multipliers for disasters in these states as recent experience including the Oct 2023 events in both states have shown.

DRP NB 200524: After Ten years of Namami Gange and Rs 40 000 Cr expenditure Ganga remains dirty

May 20, 2024 SANDRP1 Comment

(Feature Image: Untreated effluents being discharged in Gang river through ‘Chor’ nullah in Kanpur on May 19, 2024. Image Source: Sceenshot of ABC News Media report)

The reports this week from Ganga basin rivers clearly show that after ten years of Namami Gange and NMCG (National Mission for Clean Ganga) efforts and expenditure of over Rs 40 000 Cr, there is no improvement in even river pollution, leave aside the state of river flows or state of the rivers in the Ganga basin.

In fact, there is nothing to show that even the new STPs are making any difference to the river even with respect to the limited objective of sewage treatment. As highlighted in the report below, until and unless the governance of STPs become more transparent, accountable and participatory, there is no hope for change, no matter how much money is spent, how much new STP capacity is added or what technology is used. Only a responsive, confidence inspiring governance can make a difference. But there is no interest in working in that direction from the government.

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

May 6, 2024May 7, 2024 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.

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.
