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.

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

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.

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.

The massive leakages in penstock of Lambadug Hydro Electric Project (HEP) on May 10 2024 morning have caused extensive damages in Multhan market area of Kangra district in Himachal Pradesh. The sudden leakages turning into a flash flood spell occurred around 08:00 am on May 10, 2024. As per reports the deluge containing mud and debris spread over 400 meter of market and invaded about 50 homes, 80 shops apart from damaging cash crops over 6 acres farming land.

The incident created panic situation for 150 families living in the area. Several residents had to run to save their lives. The project and administration officials remained unavailable to control the situation for hours. With no help in site, the local people had to divert the gushing currents towards Lambadug river to prevent further damages to their homes and properties.

Tawi Barrage & Riverfront Projects in Jammu destroying river, inviting disaster

(Feature Image: a picture of Tawi Riverfront and Real Estate Development uploaded on Jammu Smart City website)

Tawi Riverfront Development (RFD) project in Jammu symbolizes the fallacy of most of the RFD projects in India. The city owes its historical relevance, cultural legacy and gradual prosperity to the river. But in return the Tawi has been witnessing typical urban river problems of gradual decline in flows, continual rise in solid and liquid waste pollution, encroachments and riverbed mining. And as is the case with most of urban rivers, instead of taking effective measures to address the existing threats, the government here has been pumping crores of rupees into an artificial lake and RFD project for over past one and half decade in a non-transparent and questionable manner.

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.

(Feature Image: Google Earth Image showing location of 6 proposed dams in Kalesar national park area by Haryana government)

In a welcome judicial intervention, the Supreme Court on April 24, 2024 has stayed building of four dams inside Kalesar National Park in Yamuna Nagar district of Haryana. Issuing notices to Centre and Haryana governments, the apex court noted that the dams namely Chikan, Kansli, Khillanwala and Ambawali would not achieve the intended purposes and would prove detrimental to wildlife, biota and eco-system of the National Park.

Disappointingly the National Board of Wildlife (NBWL) had approved the dams ignoring the Wildlife Institute of India (WII) report warning about adverse impacts of these dams on the terrestrial as well as aquatic biodiversity in the protected area. As per the WII report, the Irrigation Department, Haryana had planned building of six dams costing about Rs. 125 cr. on streams feeding Pathrala river in the national park.

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.
