The Char Dham All Weather Road Project has been approved by National Green Tribunal (NGT) on September 26, 2018. The controversial project has evoked several environmental concerns right from the inception stage.

Almost more than one and half year into the unmindful implementation of the project, the risks and fears associated with the project are clearly visible throughout the construction route. In last few months, several independent reports have also raised serious concerns over the haphazard manner in which the project is being executed through sensitive hilly terrain.  Continue reading “Char Dham Highway Project: An overview”

DRP: 1 Oct 2018: Hungry Water Effect due to Dams & Unsustainable Sand Mining Worsened Kerala Floods

Dams and reservoirs make rivers sediment-starved and menacing manifold downstream. While heavy rainfall is also a key factor behind the floods, hungry water had a more pronounced effect, says D. Padmalal, Scientist and Head, Hydrological process group, National Centre for Earth Science Studies.

– “When the sediment transport is interrupted, the potential energy of the hungry water released from dams will scour the river banks downstream, uprooting trees or riparian vegetation and damaging bridges and other engineering structures,” explains Dr. Padmalal. Overloaded with silt and clay from the eroding river banks, the highly turbid and viscous water clogs drainage channels. Subsequent discharge of water from the dam will lead to inundation and waterlogging of large areas.

– Hungry water can also develop in high gradient river channels devoid of adequate quantity of sand and gravel, especially during periods of high rainfall. “Years of uncontrolled sand mining have left most of the rivers in Kerala depleted or exhausted of sand and gravel. This creates a situation similar to the release of hungry water from dams,” notes Dr. Padmalal. When the river channel has adequate supply of sand and gravel, the potential energy of the water is used to transport the mixture. The water does not scour the banks or turn muddy.

NBWL pushes Lower Demwe HEP on Lohit River in Arunachal Pradesh based on fudged WII report

The Minutes of 50th Meeting of Standing Committee (SC) of National Board of Wild Life (NBWL), held on 7th Sept 2018, were made available on 26th Sept  2018. On viewing the Minutes of Meeting, the petitioner to NGT Bimal Gogoi wrote to the Chairman and the Members of SC Of NBWL about the recommendation of the SC of NBWL on Demwe Lower Project.

URGENT: Grant of wildlife clearance to Demwe Lower project based on faulty WII report is shocking and should be reversed

Dear Dr. Harsh Vardhan and Members of the Standing Committee of the NBWL,

Greetings from the Northeast! I have just perused the minutes of the 50th meeting of the SCNBWL and I am shocked to see that your committee has granted wildlife clearance to the 1750 MW Demwe Lower project based on a seriously flawed report of the Wildlife Institute of India (WII).

DRP: 24 Sept 2018: If NGT Can’t Provide Environment Justice…

Unless immediate corrective action is taken, the NGT which has till recently served as an institution to provide environmental justice, will increasingly become an institution to perpetuate environmental injustice. If this is to happen, it will be a sad day for both India’s environment and democracy; writes Ritwick Dutta.

– Last few months have seen a massive decline in public confidence in the NGT. The first wake-up call was in July when the new chairperson of the NGT commented that around 50% of the petitions before the tribunal were filed by “blackmailers”. Nothing could be more distressing because this comes from an institution that was created to protect the rights of the people. Recently, the decision of the chairperson of NGT to rehear 18 cases, which were reserved for judgment, has raised concerns about both propriety as well as legality.

– The NGT, over the last two months, seems to have evolved four approaches to deal with litigations. First, dispose of existing cases. Second, form committees, comprising mostly people who were responsible for the problem, and outsource even adjudicatory functions. Third, refuse to entertain matters on the ground that the govt has approved the project or other hyper-technical grounds. And finally, rehear cases which were earlier reserved for judgment.

– One is not expecting the NGT to always give judgments in favour of those who approach it for protecting the environment. Rather, the cause for concern is the general reluctance of the tribunal to hear matters on merit, to consider the decision of the govt as virtually sacrosanct and submissions of project proponents as cast in stone. It must not be forgotten that the NGT is not a special tribunal, but a specialised tribunal set up to adjudicate on complex environmental issues through the use of both judicial and technical expertise.

DRP: 17 September 2018: How Much of This Drought Is Man Made?

  1. Gujarat suffering due to political use of water for elections in 2017.
  2. Rajasthan given more water for elections there in 2018. Will Punjab, Haryana suffer now?
  3. Kerala drought: how much could have been reduced if dams were operated more prudently?
  4. North Interior Karnataka is suffering, but Krishna basin dams are almost full? Issue of unsustainable cropping patterns, groundwater overuse, and neglect of recharge & regulation?

Gujarat Water scarcity looms large with state receiving only 74% rainfall so far

  • Kutch and North Gujarat are likely to face severe water scarcity this year, officials said. The Kutch region has received a mere 26.51 percent of average rainfall so far, while North Gujarat has received 42.93 percent, central Gujarat 66.83 percent, Saurashtra 72.20 percent and South Gujarat the highest 94.79 percent.
  • However, the Sardar Sarovar Dam is filled up to 125.82 meters, and it can provide drinking water for the entire state till the next summer, the govt said. As per Govt. storage in Sardar Sarovar Dam on the Narmada, which will be enough to meet the state’s need for drinking water through the next summer.
  • The Narmada water will also be used to fill up empty dams in Saurashtra including Aji 1, Macchu 2, Vadod and Ankadia through the Sauni scheme, officials said.
  • “The state govt will provide 20,000 cusecs water for the next 20 days to save the crops in water-starved areas,” Deputy CM Nitin Patel told reporters in Gandhinagar said.
  • “We plan to fill up 400 big and small ponds in North Gujarat by Narmada water through canals and pipeline network of the Sujlam Suflam scheme,” he said.
  • “We also plan to fill the dams in Saurashtra region and provide water for irrigation from Narmada Dam under the SAUNI scheme,” he said. https://www.firstpost.com/india/water-scarcity-looms-large-in-gujarat-with-state-receiving-only-74-rainfall-so-far-this-monsoon-says-government-5188271.html (15 Sept. 2018)

Himachal Pradesh Rajasthan quietly given extra water by BBMB to improve BJPs Poll prospects A detailed story about how BBMB, controlled by Central Power Ministry, released excess water to BJP ruled Rajasthan this poll year, which has deepened the water availability at BBMB dams this year. This is not that the first time that the water releases have happened to achieve poll objectives. https://www.huffingtonpost.in/2018/09/16/rajasthan-quietly-given-extra-water-by-bhakra-dam-board-to-improve-bjps-poll-prospects_a_23528788/  (14 Sept. 2018)

Rajasthan Rainfall deficit in many districts As per IMD, Badmer district of Rajasthan has received rainfall 48 percent below normal till Sept. 16. Similarly rainfall deficit in Hanumangarh 58 percent so far. Jallor district is facing maximum rainfall deficit of 60 per cent less than normal. Likewise the rainfall in Pali district is 35 per cent below the normal and in Jaislmer is facing a rainfall deficit of 38 per cent. In Western Rajasthan it rained only 193 mm during entire monsoon season causing a  deficit of 24 per cent below the normal.

DRP: 10 Sept 2018: NIDM Lecture on Role of Dams in Kerala Floods

National Institute of Disaster Management, Ministry of Home Affairs, Govt of India invited Himanshu Thakkar, Coordinator of SANDRP,  to speak on the topic at IHC on Saturday. At the packed hall with participants that included members from Central Water Commission, National Disaster Management Authority, Embassies, Media and Civil Society,  the speaker explained how unwise and  unaccountable operation of dams, violating all norms, hugely contributed to the proportions of the Kerala flood disaster. Giving the example of Idukki dam, he showed, how if the dam was operated as per rule curve,  its contribution to the floods could have been reduced by over 50%. Similar is the story of other dams in Kerala.

DRP: 3 Sept 2018: CHINA HAS STARTED DECOMMISSIONING DAMS

In a mountain village in southwest China’s Sichuan province, authorities have demolished seven small dam projects this year along a river to clear illegal developments in a new nature reserve. The demolition is part of a nationwide programme to close hundreds of tiny and often ramshackle dams and turbines and bring order to China’s massive hydropower sector after years of unconstrained construction.

The dams sat on an unnamed tributary of the fierce and flood-prone Dadu river, which feeds into the Yangtze, Asia’s largest and longest river, where the government says the “irregular development” of thousands of small hydropower projects has wrecked the ecology. But green groups say the campaign will not necessarily save the environment because it will not affect big state hydropower stations, which they say have caused the most damage.

On the 48 km Zhougong, authorities have already demolished small projects built in nature reserves or encroaching upon new “ecological red lines” drawn up to shield a quarter of China’s territory from development.

The government says small dams have disrupted the habitats and breeding patterns of many rare species of fish, although green groups argue the damage wrought by bigger dams is more severe, with entire towns and ecosystems submerged in water, which they say increases the risk of earthquakes, landslides and even climate change.

DRP: 27 Aug 2018: WRONG Management of DAMS Create FLOODS, Accept Officials and Experts

Accepting that reservoirs operation and flood management in India lack scientific supports, Madhavan Nair Rajeevan, Secretary, Ministry of Earth Sciences, in an interview has revealed that dams and water reservoirs need flood management systems that use scientific methods to understand when the time is right to open the gates.

“As per my understanding, no big reservoir has a decision support system. So we don’t know when to open them, how to open them… I am not attributing the Kerala floods to an individual. There is a common perception that in India most of the flood management systems are not supported by science… I am very sure we don’t have the decision support system and we need it.” https://indianexpress.com/article/india/not-just-kerala-no-scientific-dam-water-management-across-india-madhavan-nair-rajeevan-secy-earth-sciences-5322003/  (24 Aug. 2018)

In another interview he says that while Kerala records among the highest amounts of rainfall in the country, the State did not have a flood warning system in place. He added that while there were several sophisticated tools to anticipate extreme weather events, India still lacked a mechanism to effectively deploy them. https://www.thehindu.com/sci-tech/energy-and-environment/reservoirs-not-managed-using-a-scientific-decision-support-system-m-rajeevan/article24785253.ece  (26 Aug. 2018)

Further in a detailed interview, he pitches for ‘decision support systems’ at dams, acknowledges the challenge of climate change, warn against repercussions of ‘fast-warming’ Indian Ocean. https://indianexpress.com/article/india/kerala-floods-m-rajeevan-ministry-of-earth-sciences-met-department-5324840/  (26 Aug. 2018)

DRP: 20 Aug 2018: Kerala Is Recovering From Unprecedented Flood Disaster, Will It Be Cauvery Or Krishna Basin Next?

Well-known ecologist Madhav Gadgil, founder of the Centre for Ecological Sciences at the Indian Institute of Science, Bengaluru, has described the devastating floods in Kerala as a man-made disaster and a reaction to the illegal excavations and stone quarrying done over a decade. https://www.hindustantimes.com/pune-news/illegal-forest-land-acquisition-major-reason-for-floods-in-kerala-says-ecologist-madhav-gadgil-calls-it-man-made-disaster/story-vMHPKUH623GEnjyQHI09NP.html  (19 Aug. 2018)

Further speaking to various regional media, Madhav Gadgil has said that irresponsible environmental policy is to blame for the recent floods and landslides in Kerala. He also called it a “manmade calamity”. He said that the committee report had recommended to protect the resources with the cooperation of local self-govt and people, but those recommendations were rejected.

He also pointed out that quarrying is a major reason for the mudslides and landslides. Other environmentalists also point fingers at the extensive quarrying, mushrooming of high rises as part of tourism and illegal forest land acquisition by private parties as major reasons for the recent calamity. https://energy.economictimes.indiatimes.com/news/power/kerala-floods-the-ghost-of-past-environment-policy-returns/65436707  (17 Aug. 2018)

Dams should never be filled before the end of the monsoons. Because then one doesn’t have any solution but to release the water in the surrounding areas: Himanshu Thakkar, SANDRP says as one of panellist discussing role of dams in aggravating Kerala floods.

Here is admission about sudden, excessive releases and not foreseeing the coming disaster. The Kerala crisis could have been contained had the state “gradually released” waters from at least 30 dams, officials said, adding that the local authorities failed to foresee the imminent danger with high rain prediction. “Such floods have probably recurred after 100 years, exposing the state’s unprofessionally run reservoir management system and unpreparedness on disaster mitigation and disaster resilience, an official pointed out. https://timesofindia.indiatimes.com/city/kochi/gradual-dam-water-release-could-have-contained-crisis/articleshow/65436339.cms  (17 Aug. 2018)

DRP: 13 August 2018: Existing Sediment Management Draft Policy Promoting Navigation & Not Rivers’ Health

Traditionally, our river management strategies are mainly focused on the water flows, including flood management, and these have resulted in various interventions such as dams, barrages, canals and embankments. Most of these interventions have had very little consideration for sediment transfer and even if they did, they were generally defunct within a few years of their operations either due to improper design or inadequate maintenance.

A long-term sediment management strategy has never been a part of any protocol of river management, not just in India, but in several other parts of the world. It is amply clear that sediment management must form an important component of management strategies for the Himalayan rivers. The Union Water Ministry has recently circulated a draft policy on sediment management.
