Amid concerns over safety and construction quality, the Polavaram project work has moved during 2025 to achieve Dec. 2027 completion target. However, not much progress has been made regarding the backwater study and addressing the issues of affected tribals and areas in Telangana, Odisha and Chhattisgarh. Meanwhile, after failing to push PBLP (Polavaram Banakacherla Link Project), the Andhra govt has proposed another contentious PNLP to divert Godavari River waters. The Stop Work order issued by the MoEF in 2011 remains suspended for all these years, making a mockery of the MoEF regulations. Wrapping up the available information, this overview shares the year-round updates on safety, progress, backwater study and linking plans related to the controversial Polavaram dam project in 2025. Our previous overview on the project can be seen here.

DRP Nov 3 2025: Safety Assessment of 5000 Indian dams pending

November 3, 2025November 4, 2025 SANDRPLeave a comment

At a recent meeting in Pune, Secretary of Union Ministry of Jal Shakti said that safety assessment of about 5000 large dams, out of total around 6000 in India is pending as per the following PIB press release. He went on to urge acceleration of dam safety assessments across the country. This is a worrying situation, coming straight from the secretary of the concerned Union Ministry. It again underlines the sorry situation regarding dam safety in India.

DRP NB 060125: Concerns about & Contradictions in CGWB’s Reports

January 6, 2025January 6, 2025 SANDRPLeave a comment

The Central Ground Water Board (CGWB) released two important reports last week. While the Annual Ground Water Quality Report 2024 reveals rise in nitrate fluoride, arsenic and uranium contimination of groundwater resource in India, the Dynamic Groundwater Resource Assessment Report 2024 claims substantial rise in annual groundwater recharge and decline in extraction of the resource.

As per the first report, the number of districts affected by high nitrate levels in groundwater has gone up to 440 (near 56% of all 779 districts in country) from 359 found in 2017 assessment which means in 7 years 81 more districts have been found having excessive nitrate levels in groundwater. This should concern us from a number of points of view.

This annual overview focusses on the functioning of National Dam Safety Authority (NDSA) and related institutions in 2024 to understand if the functioning of these institutions have made Indian Dams any safer? Here functioning of Central Water Commission (CWC) is also important as CWC people head all the dam safety panels. The dam safety related institutions were formed following the passage of Dam Safety Act 2021 and hence there were promises and hopes that these institutions will make our dams safer.

DRP NB 231224: Can we expect the Supreme Court to be more effective this time on Wetlands?

It is indeed good to see an Editorial in a newspaper on the important issue of wetlands protection and rejuvenation. The Supreme Court’s order on wetlands last week shows its concern over the threat to wetlands as a natural feature of the environment that is under serious threat. The court ordered the protection of about 30,000 wetlands (each with area more than 2.25 ha) over the 201,503 protected by an order which it issued in 2017, and asked states to ensure their demarcation and ground-truthing which involves closer verification, within three months.

The order is in response to a PIL that said the Central government had abdicated its functions under the Environment Protection Act, 1986, to protect the wetlands. The petition also sought the identification and protection of around 5,55,557 wetlands which are less than 2.25 hectares in size. The court is likely to consider the proposal in March. One hopes the SC also gives effective orders for their protection.

DRP NB 28×24: Hydropower Impacts on Biodiversity

A new study of available scientific publications on impact of Hydropower projects on biodiversity provides a thorough review of the subject. The review does not directly give a call not to construct more such destructive projects. But it is useful for anyone concerned about the impact of dam projects on rivers.

The study discusses the impacts of hydropower projects on both aquatic and semi-aquatic species in riverine ecosystem and cumulative impacts spatially and temporally across river basins. Dams disrupt longitudinal connectivity and act as physical barriers in upstream-downstream movement of species. Upstream of dam, there is static water environment rather than flowing river environment. In the downstream, the hydropower projects adversely affect the water flow, sediment flow, thermal regimes, affecting water quality and environmental cues for the fish movement. All these also affect the floodplains both upstream and downstream.

DRP NB 230924: Role of rivers in the birth of governments

September 23, 2024September 23, 2024 SANDRPLeave a comment

(Feature Image Source: The Economic Origins of Govt)

Interesting research published in 2023 suggests that archaeologists and economists are now learning that dynamic, shifting rivers also created conditions that triggered people to develop some of the first organized govts on the planet.

In the research published in The American Economic Review Robert Allen and two co-authors found that Agriculture and large settlements emerged alongside rivers because they could tap into the gifts of rivers: close access to water and fertile soil. But rivers can move and take those gifts away. So, society developed organized govts to work collectively to regain their access to those gifts.

DRP NB 160924: Urban Flood lessons from Vadodara, Vijaywada

Like every monsoon, a number of cities have faced catastrophic floods in SW monsoon this year. Vadodara and Vijaywada have got the media attention more than any other city for urban floods this year. In both cases a number of factors are common: role of upstream dams, encroachment on water bodies including rivers, lakes, streams, role of illegal sand mining particularly in Vijaywada, not having learnt any lessons from past flood disasters.

It is interesting to see Andhra Pradesh CM hinting at bringing HYDRAA like enforcement institution to remove encroachments on Budameru and other water bodies. Considering the nature of his politics and track record, it is doubtful if this NDA CM will take such a bold step, but it is certainly worthy of consideration for almost all urban areas in India.

DRP NB 020924: HYDRA to protect water bodies in Hyderabad – a landmark move?

The Hyderabad Disaster Response and Asset Monitoring and Protection Agency, or Hydra was established under GO 99, dated July 19 2024. A task the agency has taken up in all seriousness is protection of water bodies in the Hyderabad Capital Region (it includes 4 districts). To begin with it has started demolition of buildings illegally built inside the Full Tank Area (FTL) and Buffer area of the water bodies.

In July, Telangana Chief Minister Revanth Reddy replaced the Enforcement, Vigilance and Disaster Management (EVDM) wing of the government with Hydra, a body mandated to tackle illegal encroachment on water bodies in the Greater Hyderabad Municipal Corporation (GHMC) limits and surrounding areas. Its strength was upgraded from around 800 to 2,200 and its officials came directly under the principal secretary, municipal administration and urban development or the CM himself. “Hydra will also ensure the protection of water bodies in and around Hyderabad,” former EVDM commissioner and Hydra chief A V Ranganath said during its inception.

DRP NB 120824: Chalakudy community demand Prudent Dam Management Plan

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.
