IPCC report says deafening fire alarm is on, 1.5° C goal is improbable. But we are busy lighting new fires

The Intergovernmental Panel on Climate Change (IPCC) has released a special report[i] titled “GLOBAL WARMING OF 1.5° C”. In the official Press Release on Monday, Oct 8, 2018[ii] from Incheon, South Korea, IPCC said: “Limiting global warming to 1.5° C would require rapid, far reaching and unprecedented changes in all aspects of society, the IPCC said in a new assessment.” In reality, the world is experiencing much bigger impacts of 1°C rise than what IPCC projected and that would also be true for 1.5° C.

DRP: 8 Oct 2018: “WELCOME CHANGE! Kerala Depletes Reservoir in Anticipation of Deluge from Cyclone”

In spite of all the protests against criticism of Floods worsened by Dams in Kerala in Aug, its refreshing that Kerala now accepts needs for better operation of dams with IMD red alert in three districts:

– Senior officers expressed confidence that the dams can contain the flood waters even if it rains continuously for four days. Better late than never, commented experts on the Kerala State Electricity Board’s (KSEB) decision to keep the water level low. “We’re prepared to face any eventuality. There won’t be any need to open the dam shutters even if it rains continuously for four days. We’re maintaining the water level low in major dams. The water level in Mattupatty dam is close to the full reservoir level and we’ve decided to release water from Thursday. The situation is under control and there’s no need to panic,” said KSEB chairman N S Pillai.

The Singing River: Story of America’s Largest Free-flowing river

As we approached a bridge on the rumbling green river, I concentrated all my senses to my ears. After all, we were about to cross the Singing River. Legend has it that a low humming sounds rise from the Pascagoula River[i], heard only by a few. Poignant stories of love and loss are interwoven into the sounds of the river.

Char Dham Highway Project: An overview

(Feature image Source Char Dham Road ProjectL Stairway to heaven or highway to hell by Siddharth Agarwal)

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”

Role of dams in Kerala’s 2018 floods

ABSTRACT: Many independent observers have argued that dams have played a role in increasing the proportions of Kerala flood disaster during July-Aug 2018. This article shows that Kerala dams violated many basic norms and if operated prudently, could have helped. It shows how post dam floods are different than pre dam floods. It lists the steps that would help in future disasters involving dams. The lessons are useful for all large dams of India.

In theory, every dam can help moderate floods in the downstream areas, as long as and as much as the dam has space to store water. In fact, every action that helps to store, hold, recharge (to groundwater aquifer), delay flow of rainwater from the catchment to the river would help moderate flow and hence flood in the river. Our catchments are fast losing that capacity, with continued destruction of natural forests, wetlands, local water bodies and also soil’s capacity to hold water.

CWC Flood Forecasting: Anomalies between Website and SOP Document

Central Water Commission (CWC) is the only agency in India doing flood forecasting, it becomes very important to understand what CWC does in this regard. The CWC flood forecasting website[i] is the main media through which CWC provides the flood forecasting. CWC has also published on its website, the document giving Standard Operating Procedure (SOP) for flood forecasting in 2018[ii]. The Home page of the CWC’s flood forecasting site says that CWC provides Level forecasting for 166 sites and Inflow forecasting for 60 sites. SOP document, however, gives these figures in Table 1, but in Table 2 (as also the full list given in Annexure 1.1 of SOP document), it gives state wise break up for 182 Level forecasting and 93 Inflow forecasting sites. So we can see anomalies in these two sources even about the number of forecasting sites.

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.

Date : September 26, 2018

To: Dr. Harsh Vardhan

The Chairperson,

Standing Committee of the National Board for Wildlife,

New Delhi.

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.

Overview of CWC Flood Monitoring Sites 2018: INDIA

Central Water Commission is the only agency doing flood forecasting in India. As per CWC’s Flood Forecasting website[i] the Data Flow Map has information about 226 Flood Forecast Sites in the country comprising of 166 Level Forecast Sites and 60 Inflow Forecast Sites. It also monitors 700 Flood sites, information made available through List Based Exploration and Hydrograph View, but no flood forecasting is done for these sites.

In order to better understand the CWC’s flood monitoring and forecasting work, SANDRP has published report of CWC’s Level Forecast, Inflow Forecast and level monitoring sites in 5 zones of North India[ii], North East India[iii], East India[iv], South India[v] and West India[vi].  Through this report, we have presented all the data at one place with links to separate zone wise reports with detailed description.
