As we saw in stories in last week (e.g., Luhri HEP in Himachal Pradesh) and see this week (Vishnugad Pipalkoti in Uttarakhand and Dibang HEP in Arunachal Pradesh), a number of under construction projects regularly face disaster, which includes deaths and destruction on large scale. We have been narrating stories related to disaster at such projects regularly in the past too.

It is rather rare when we find anything in media about celebrating our monsoons. We find this week more than one piece about such celebration in various ways including through creating works like Bollywood songs and poetry in various languages of India.

In a detailed article famous Bollywood related author Jerry Pinto writes about the fascinating Bollywood songs related to monsoon and their picturization. He writes that the great tradition seems to be fading out, but hopefully that will not be the case. Incidentally the article should have mentioned the name of one of the best lyricist, author and film maker, Gulzar, who has shown more love for monsoon that possibly anyone else in Bollywood.

DRP 080724: Why IMD & CWC are unable to improve forecasts, reporting & help improve flood management?

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 sequence of events over the last two decades that ended this week with white paper on Polavaram project being released by the newly elected Andhra Pradesh govt underlines urgent need for an independent assessment of the multi-state Polavaram Project on Godavari River in Andhra Pradesh.

The story of the project similar to, though a bit longer than that of the ill-fated Kaleshwaram Project of the neighbor Telugu speaking state of Telangana. Both are ill-conceived, expensive, high impact projects on same Godavari River, both taken forward without sufficient studies and implemented without sufficient checks and balances.

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.

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

(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 130524: Unreliable Hydropower poses new challenges for India

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

May 6, 2024February 28, 2026 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.

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.
