A recent CIFRI (Central Inland Fisheries Research Institute) report submitted to NGT is an eye-opening official document about the fish diversity in Yamuna. The report says that overall native fish species have declined sharply in the river not only in number but in size also due to habitat degradation, pollution and increasing presence of invasive fish species.

The report admits that construction of Farakka barrage has led to complete elimination of Hilsa fish in lower segment of river since 2010. Among other recommendations the report has suggested maintenance of continuous flows in the river and addressing sources of pollution.

Indeed, the freshwater fish species are key indicator of health of a river eco-system and the fish diversity in Yamuna has been pushed to brink by the water abstraction, unsustainable riverbed mining activities and ever-increasing pollution of river waters besides other factors.

DRP 021224: Why Ken Betwa Link should not go forward

December 2, 2024February 27, 2026 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.

Marking World Fisheries Day 2024, this yearend round up complies the top ten reports outlining how the fish and fisherfolks in India have been facing existential crisis due to govts’ apathy, various developmental projects and growing climate change threats. The first part of the annual overview covering positive developments on fish, fisheries and fisherfolks can be seen here.

DRP 181124: Kumbh 2025: Can we treat Ganga as River All Round the Year?

The government website on Maha Kumbh (https://kumbh.gov.in/) has started the countdown to Mahakumbh 2025 to be held in Prayagraj from January 13 to Feb 26, 2025. It says today that it is 55 days to the beginning of Mahakumbh. But the Ganga is highly polluted in Prayagraj, and even upstream even in Uttarakhand, the state where it originates as the following reports this week say and as we all know.

The reason why the largest congregation on earth happens here every 12 years is because, as puranas say, Ganga water turns into Amrit on these holy days. So how will the Ganga water turned into Amrit at Prayagraj in 55 days?

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

November 7, 2024 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.

DRP 041124: Study says Big Dams are costly gambles or frauds?

An interesting study reported this week reveals Big Dams are costly gambles and explains why this is so. In fact, the explanations go on to reveal that this is by design, the costs are systematically under estimated and benefits are exaggerated, so the dams fail to provide the promised benefits. So Big Dams are actually not gambles, but frauds. They get away with all this due to lack of transparency and accountability in the governance, the study reveals.

For those following the global debate on big dams over the decades know that there is nothing new here. A number of studies earlier exposed all this, including the Independent Review of the Sardar Sarovar Project instituted by the World Bank, the World Commission on Dams report, the India Country study done for WCD, among others.

यमुना में पर्यावरणीय प्रवाह बढ़ाने के हों ठोस प्रयास

सर्दी शुरू होते ही दिल्ली में यमुना नदी में झाग की समस्या चरम पर पहुँच जाती है। इसी के साथ कई दिनों तक ओखला बैराज के नीचे नदी सतह पर तैरते ‘आइस बर्ग’ की भांति दिखने वाले झाग के बड़े-बड़े खंड लोगों के आकर्षण और मीडिया की सुर्ख़ियों का केंद्र बन जाते हैं। बढ़ते नदी प्रदुषण पर नागरिकों की बढ़ती चिंताओं और नदी प्रेमियों के बढ़ते सवालों के बीच राजनितिक दोषारोपण का दौर शुरू होता है। समस्या का फौरी निराकरण करते दिखने के प्रयास में संबंधित सरकारी विभाग आनन-फानन में कुछ आधे-अधूरे कदम उठाते हैं। त्यौहार और खास तौर पर छठ पर्व समाप्त होते ही, लोगों की नदी पर जाने वाले भीड़ कम हो जाती है और दो-तीन सप्ताह बाद सब यमुना नदी में बढ़ते प्रदुषण और झाग की समस्या को भूल जाते हैं। लगभग एक साल बाद फिर से यह क्रम दोहराया जाता है जब सर्दी के समय झाग के आगोश में लिपटी प्रदूषित यमुना, नागरिकों की उदासीनता और नदी सफाई योजनाओं की नाकामी को उजागर करती है।

DRP 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.

A number of reports listed below this week throw fresh light on functioning of global water cycle, some of the findings should be seriously worrying. The studies show how the countries across the globe have water connections that go far beyond shared rivers, lakes and seas. And how these components of global water cycles are not only changing, but are under unprecedented stress and could take the global water cycles off balance.

Another study about atmospheric rivers that provides some of the largest high intensity rainfalls show that these rivers are shifting, which can have far reaching consequences for large sub-tropical areas, polar areas and others. For understanding their implications, more studies particularly focusing on shifting El Nino and La Nina streams are required.
