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

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 twelfth edition of monthly Yamuna updates and the first one of the new year 2025, rounds up the critical issues impacting the river eco-system during the past year. The updates of the past one month only hint towards the bleak future the river is heading to. Without addressing the adverse effects and exploring cost effective alternatives, foundation stones of two massive river interlinking projects namely Ken-Betwa and Parbati-Kalisindh-Chambal have been laid. The work of unjustifiable Renuka and Lakhwar dams in climatically sensitive and geologically fragile region of Himalaya is going on.

Exactly three months back, on Sept 30 2024, we had highlighted the urgent need for credible river studies in India (https://sandrp.in/2024/09/30/drp-nb-300924-focus-on-river-studies/). A new research report published last week in Nature has corroborated this, showing that volume of research across global south is disproportionately small compared to need based on basic population, water withdrawals and water consumption.

Based on review of 4237 publications using machine learning and desk review of 325 publications, analysis of 4713 case studies across 286 basins, it shows that river research currently in global south is predominantly led by global North institutions, thus the river research is shaped by selection of theme and locations done by such institutions.

DRP 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 021224: Why Ken Betwa Link should not go forward

SANDRPLeave a comment

A detailed report this week based on extensive field visit and interview of the concerned persons shows once again why there is no justification for Ken Betwa Link starting from lack of hydrological justification: There is no credible evidence or are not credible figures proving that Ken has surplus water and Betwa is deficit. The project will actually facilitate export of water from drought prone Bundelkhand in addition to bringing massive adverse impacts and as a former Panna collector said, will keep the upstream Ken Basin area permanently backward. This was also proved during the SANDRP initiated Ken Yatra from Ken Yamuna confluence upstream to the origin of the river.

The whole exercise of getting clearances for the project has been an exercise in manipulations at each step of the way, including EIA, Public Hearings, EAC process, Environment Clearance, Forest Clearance, Wildlife clearance and gram sabha clearances. This is also true as this report shows, for the people to be displaced by the project. The scathing CEC (Central Empowered Committee appointed by the Supreme Court) report on its wildlife related issue has not even been considered by the Supreme Court. We hope the Supreme Court will soon consider this and put a stop to the mindless project.

The ongoing protest by the Mother’s Union against sand mining in Dudhnoi River along the Assam Meghalaya border has brought to focus the serious implications of unsustainable sand mining, whether legal or illegal. The campaign has wide based support from the Garo Students Union, All Bodo Students Union, Krishak Mukti Sangram Samiti and other groups.

The campaign has highlighted that due to use of motorized equipment to extract sand, the water level in the Dudhnoi river is dropping hugely, including during rainy season. The campaign has also pointed out that the forest, mining, transport and police departments have been allowing over loaded sand laden dumpers with or without proper challans.

WFD 2024: MASS FISH KILL in Indian Rivers, Wetlands Continue…

SANDRPLeave a comment

Over the past several years Indian rivers, wetlands have been witnessing mass fish death incidents primarily due to decreasing flows, increasing pollution and other anthropogenic activities. As we celebrate World Fisheries Day 2024, SANDRP compiles the reports revealing mass fish kill incidents in our rivers and wetlands over the past one year across. The first part of year end analysis has covered positive development on fish, fisheries and fisherfolks and the second part has highlighted how fish and fisherfolks have been facing existential crisis on account of adverse impacts of developmental activities in the country.

DRP 111124: URBAN RIVERS in focus this week

This week there is some interesting news about a number of Urban rivers including Pune Rivers, Musi (Hyderabad), Chennai Rivers, Budha Dariya (Ludhiana), Gomti (Lucknow). All the news underlines some serious existential issues for Urban Rivers and raising of voices about it by local communities, governments or legal authorities.

In fact, this is part of a trend that is going on for some years. This sounds like a positive development. But unfortunately, it is not. In fact, this is sign of deteriorating condition of Urban Rivers and increasing Urban footprint on our rivers, going far beyond the boundaries of the cities. Closer examination shows that in spite of some efforts from environmental groups, local communities, some elements in the governments and the courts, the condition of our Urban Rivers is getting worse, much worse than the state of our rivers in general. More worryingly, there are almost no success stories, except some temporary respites at some places.

Yamuna Manthan 061124: Save River from ‘Illegal’ Sand Mining

SANDRP1 Comment

(Feature: Members of Haryana Anti Corruption Society, Yamuna Nadi Mitra Mandli, Bhartiya Kisan Sangh, Yamuna Nagar raising concerns over unabated unsustainable riverbed mining in Yamuna in Gumthala Rao, Karnal on Oct 07, 2024.)

Large scale riverbed mining has become most underestimated and least discussed threat for Yamuna rivers. While increasing pollution has turned the river stretch between Delhi and Agra ecologically dead, the rampant sand mining has been severely damaging the Yamuna eco-system in upper and lower segments.

Presently, the mining menace is quite rampant in Paonta Sahib, Yamuna Nagar, Saharanpur, Karnal, Shamili, Panipat, Sonipat, Baghpat and Ghaziabad districts along the river in upper segment. Similarly, in lower segment the main stem of river as well as its key tributaries Chambal, Sind, Betwa, Ken have been bearing the burnt of unsustainable sand mining.

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.
