DRP News Bulletin 15 October 2018: Reuters Corroborates that Dams Played Major Role in Kerala Floods

International news agency, after independent research, have corroborated what SANDRP has been saying: Mismanagement of dams played big role in worsening Kerala floods.

-“The release could have started earlier so that by Aug. 9 there would have been left-over capacities in the reservoirs to store the water,” said Biswajit Mukhopadhyay, director of water resources at U.S-based engineering firm IEA, who analysed some of the publicly available data at the request of Reuters.

– Still, dozens of flood victims interviewed by Reuters, who live in villages dotting the banks of Kerala’s biggest river, the ‎244 km Periyar, say they faced no floods despite torrential rain in late July and early August. All of them said waters only rose overnight on Aug. 15. That was when more intense rainfall forced KSEB to rapidly ramp-up releases of water from Idukki and Idamalayar reservoirs, which feed into the Periyar.

– Kerala’s revenue secretary and head of disaster management, P.H. Kurien, told Reuters he has twice written to KSEB requesting EAPs and has yet to receive them. KSEB’s Pillai said EAPs and dam operation manuals were still being prepared. CWC said it was working with Kerala’s government to speed this up. The Kerala Chief Minister’s office did not respond to requests for comment. https://widerimage.reuters.com/story/did-dams-make-indias-once-in-century-floods-worse  (11 Oct. 2018)

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 News Bulletin 24 September 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.

Similar is the story of other dams in Kerala.
