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)

The Ken Yatra while going through the Panna district were told by Project Affected People that the Pawai Medium Irrigation Project (PMP) under construction is displacing the people without just compensation or rehabilitation.
The Ken Yatra observed that the construction work of the PMP is happening in full swing in Madhya Pradesh. The dam is being built at ‘Tendu Ghat’ on Ken River in Panna district to supply irrigation water to 9952 hectares (the board at the project site erroneously says it will irrigate 30 000 ha) of agricultural land falling in Pawai and Gunnor tehsils. The construction work also involves creation of a massive canal, including a few aqua-ducts on Ken river and its tributaries.

On Sept 1, 2017, Reuters published a report[i] about Interlinking of Rivers, with focus on Modi flagging off work on Ken Betwa Project. The report was carried VERY widely, including in local, national and international media. [This note was sent as a letter to a number of persons at Reuters and Thomson Reuters on Sept 2, 2017, there has been no response so far as I publish this several hours later.]
Unfortunately, it’s a biased, very misleading, erroneous report with factual inaccuracies that one does not expect in a Reuters report. Continue reading “REUTER’s biased, misleading, erroneous reporting about Ken Betwa Project”
Can you imagine a project-not any project, perhaps India’s largest irrigation project till date- going on for years without most statutory clearances? Can you imagine a project on which Rs 7000 Crores have been spent already but its Dam height (FRL – Full Reservoir Level) is yet undecided? Can you imagine a project whose canal works are ongoing in full swing, without having any idea of the submergence? Can you imagine a Public Hearing where the Project Engineer says that the meeting is only about compensation not about environmental impacts or fundamental questions? Can you imagine a state which is set to lose thousands of hectares of rich forests, protected areas, villages for a project of a different state, but is happy to oblige? Can you imagine a Ministry which turns a stony Nelson’s Eye to a project continuing right under its nose without Environmental Clearance, Wildlife Clearance or Forest Clearance?
Guest Blog by: : Karthik Teegalapalli (email@example.com) a researcher with the Nature Conservation Foundation
In April 2014, the Forest Advisory Committee (FAC) decided to deny clearance to the 3000 MW Dibang Multipurpose Hydro-electric Project, the largest capacity hydro project in the country proposed to be developed by the National Hydropower Power Corporation (NHPC) in the biodiversity-rich Arunachal Pradesh State (Saikia 2014). The project was also denied clearance in July 2013. More recently though, the project has been recommended forest clearance by the FAC and Environment Clearance by the Expert Appraisal Committee. Therefore it is pertinent to look at the impacts the project may have in some detail.
Ecological impacts The project, in its earlier version involved diversion of more than 5000 hectares of relatively undisturbed grassland and tropical forest habitat. These and the adjoining forests harbour endangered species such as tiger, leopard, serow as well as the critically endangered takin, all of which are protected under Schedule I of the Wildlife (Protection) Act, 1972 (these species are also listed as present in the area in the Environmental Impact Assessment report of the project, undertaken by National Productivity Council, Guwahati). The grasslands in the area harbour the critically endangered Bengal Florican, a grassland habitat specialist (Sinha et al. 2014). Other species recorded from the area include the critically endangered white-rumped vulture, the slender-billed vulture and the white-winged wood duck. The project site lies in an area identified by the Bombay Natural History Society as a Ramsar site and an Important Bird Area (Islam & Rahmani 2004). The habitat of six endangered plants (Aconitum ferox, Coelogyne mossiae, Dendrobium aurantiacum, Paphiopedilum fairieanum, Paphiopedilum venustum and Vanda coerulea) will be submerged by the reservoir (Chernaik 2007).
The project will also affect aquatic species; the dam will block the breeding migration of four species of fish: the Vulnerable snow trout Schizothorax richardsonii, Endangered golden mahseer Tor putitora, Near-Threatened mahseer Tor tor, and chaguni Chagunius chagunio. The recommendation of the Environmental Management Plan of the Project to establish fish hatcheries for these species is impractical and can have further damaging effects on the species due to collection of eggs and spawn from the wild population.
The project will have other collateral damages such as through Compensatory Afforestation (CA) that often involves converting an area with diverse native species into monocultures, as has been shown for other dams such as the Sardar Sarovar Dam on the Narmada river (Bhatnagar 2004). The project involves CA of a relatively large area of over 100 sq. km (double the area of forest being affected by the project). The ill-effects of this conversion particularly for the project can be expected to be higher if tree-less natural grassland habitats in Dibang Forest Division, Namsai Forest Division and Anini Social Forestry that harbour grassland habitat specialists are planted with undesired native or non-native tree species. Perhaps the irreversible loss of biodiversity in the forests and grasslands that will be diverted for the project could never be ‘compensated’.
During the construction phase of the project, an estimated 32 lakh truckloads of boulders and 16 lakh truckloads of sand is to be extracted from the Dibang river basin. Unsustainable extraction of sand and boulders has significant negative effects on geomorphology, bank stability, flood character of the river, water quality, river flow, and the biodiversity in the river basin (Padmalal et al. 2008). The project during the construction is to generate 198 lakh cubic meters of muck which will be disposed in the river bank which will cause further loss of 120 ha of river habitat. Construction of new roads (64 km) and widening of existing roads (19.5 km) will also lead to removal of trees and increase the vulnerability of the region to landslides and erosion (Chernaik 2007).
Social impacts The Lower Dibang valley is currently a region of relatively low human population density (~14/km2); the entire population of the Idu-Mishmi tribe is about 12,000. The influx of approximately 6,000 project staff (which is very likely an underestimate) for a period of 8 years or more will affect their way of life, their culture and their tradition as well as open up access to relatively moderately disturbed habitat and biodiversity in the region.
Downstream effects include those on fisheries, agricultural lands and wetlands (beels) and the dam will also increase the vulnerability of the region to flash floods. For instance, in the year 2007, flash floods caused due to sudden release of water from the relatively smaller 405 MW Ranganadi project in the Lower Subansiri district in Arunachal Pradesh swamped 83 villages and caused huge loss of lives and property in the Assam State. The project will have a considerable impact on the Dibru-Saikhowa National Park in Assam which has not been studied in detail in the EIA.
On shaky grounds A critical issue with the project is that the site lies close to an active Fault Line in the Mishmi Thrust of the Mayudia Group in Eastern Arunachal Pradesh with a history of several seismic activities including the Great Assam earthquake of 8.6 magnitude in 1950 (Figure 1, Misra 2009). In the event of an earthquake, the project poses a risk of catastrophic submergence of several villages and vast areas of forests downstream. The recommendations of the Environmental Impact Assessment (EIA) report of the project are cursory and suggest further research on the natural seismicity of the region as well as reservoir-induced seismicity, which should be the basis for the decision about the project.
Notwithstanding these, in Oct 2014 the project was cleared by the FAC constituted by the new Government, although the committee still had four of the six members who had earlier twice recommended rejection of clearance. Is this decision driven by changes made by NHPC in their project plan? Clearly not. Diversion of forests has now been reduced by a mere 9% to about 4600 hectares; instead of 3.55 lakh trees, the felling has been reduced to 3.24 lakh trees, the power generation capacity has been reduced by 2.3% and the height of the proposed dam reduced by 10 m. In fact, the FAC rejection of April 2014 was for this 10 m rejection proposal!
NHPC misleadingly and baselessly claimed that they ‘were not in a position to reduce the height of the dam any further, as it would significantly affect the power generation’. The decision to provide clearance to the project seems like a hasty one driven by the blinders of development and the consequences of such projects is evident from the fate of the Lower Subansiri Hydropower Project in the same State, also by NHPC. After 12 years since the LSHP was initiated and after an expenditure of over Rs. 5000 crores, the work has been on a standstill for the last 35 months as a result of India’s biggest anti-dam people’s movement (Dandekar & Thakkar 2014). Considering the economic, ecological, environmental and social costs of the project as well as the geophysical risk it poses, it would be prudent to withdraw the project till a credible, detailed cumulative study covering these aspects is undertaken in a transparent and participatory way. While the rest of the world is recognising the ill-effects of dams, with the largest dam removal project on the Elwha river in the United States completed just three months back, it is paradoxical that we are heading in the other direction; of building the highest dam in the country and largest capacity reservoir of the North East India without even basic studies, credible impact assessment and democratic decision making process.

PROJECT UNABLE TO SUBMIT SATISFACTORY PROPOSAL EVEN SIX YEARS AFTER PM LAID FOUNDATION STONE!
In a remarkable decision, the Forest Advisory Committee (FAC) of MoEF has rejected the forest clearance to 3000 MW Dibang multipurpose project for the second time in its meeting held on 29 -30 April 2014. In that meeting FAC considered the Dibang multipurpose project for diversion of massive 4577.84 ha of biodiversity rich forest land which would lead to cutting down of huge 3.24 lac trees.
The foundation stone of 3000 MW Dibang Multipurpose Dam was laid on 31st January 2008, by Prime Minister Manmohan Singh. Six years have passed since then but the project is yet to get the necessary forest and environment clearances. This in a way reflects the state of environment governance in India where the foundation stone of mega dam is laid without getting any necessary clearance.
This project was considered for forest clearance in the FAC meeting held on July 11th and 12th 2013. The FAC meeting minutes noted “Felling of more than 3.5 lakh trees most likely to have adverse impact on general eco-system of the area, recovery of which may be very difficult through any type of mitigate measures”.
The Expert Appraisal Committee (EAC) on River valley and Hydroelectric projects considered Dibang multipurpose project in its 68th meeting on September 23rd 2013 for environment clearance but this was in complete violation of norms. Following the “Lafarge vs Union of India and others” case of 2011, the Supreme Court of India had said that a project without forest clearance cannot be considered for environment clearance. SANDRP had pointed this out in our submission to EAC dated 20/09/2013. But EAC seemed to take no account of that.
Out of the 168 projects proposed for Arunachal Pradesh, this is the only multipurpose project. The minutes of 68th EAC meeting states that this project has dual objectives. The primary objective is flood moderation while electricity generation is its secondary objective. This is highly doubtful though since the project does not have the adequate storage capacity. On the other hand, the installed capacity of the project i.e. 3000 MW is also one of the highest among 168 hydropower projects.
The Dibang multipurpose dam is located 1.5 km upstream of confluence of Ashu Pani with Dibang river at Munli village in Lower Dibang Valley district. Construction of this dam involves two districts of Arunachal Pradesh viz. Lower Dibang Valley and Dibang Valley districts. All the project components e.g. dam, power house will be are located in Lower Dibang Valley District while reservoir which will submerge 43 km length of the river will fall in both districts. The total land requirement for this dam is 5794.142 ha out of the 5022.842 is forest area with very rich bio-diversity. Submergence of such a huge forest is one of the major concerns associated with this dam and that is why the Forest Advisory Committee (FAC) has refused forest clearance to this project.
The Dibang multipurpose project plans to construct 288 meter high concrete gravity dam with an underground dam toe power house. The reservoir of this project will submerge 40.09 sq km area. The total cost of the project at November 2007 price level was estimated at 15886.39 crores.
It is important to note that the public hearing for the project faced vehement opposition of the local people. The public hearing of the project has been halted for several times. The local people expressed serious concern regarding Dibang multipurpose project and feared that influx of outsiders for dam building will lead to a demographic imbalance in the Dibang valley. This is a serious issue since the primary inhabitants of Dibang valley are Mishmi (Idu) which is a very small community with a population of 11,023 according to 2001 census. According to NHPC estimation a workforce of 5800 people (labour and technical staff) would be needed for the Dibang multipurpose project. But All Idu Mishmi Students Union (AIMSU) has contested this figure and opined that a single project would bring about 15,000 people into the region. It is also reported that NHPC claim that the project will cause ‘negligible human displacement’ grossly undermines its harmful impacts on smaller ethnic community such as Idu Mishmis. A video of the protest by local people can be seen here – http://www.youtube.com/watch?v=m8TCUKh2hQY
No cumulative impact assessment of dams in Dibang valley has been conducted e even though 17 projects have been proposed for this region. The TOR clearance had been given to 86 MW Ithum and 3097MW Etalin HEP in the basin by EAC. Without any cumulative impact assessment study of the basin no project should be given environment clearance. People from Dibang valley has also written to previous EAC on demanding cumulative impact assessment study. A letter to EAC from a local person Raju Mimi, dated January 31st 2013 stated “Since the 3097 MW Etalin project is on agenda again for the 64th EAC meeting to be held on Feb 1st – 2nd 2013, we re-iterate our demand to have prior cumulative impact assessment of multiple hydropower projects by urgently commissioning a Dibang river basin study.”
Other Glaring Issues of Dibang Multipurpose Along with the above mentioned issues SANDRP had made detailed submission to EAC pointing to some of the glaring concerns associated with the project. Some of these issues are –
Incomplete and Shoddy Downstream Impact Assessment: The downstream impact assessment done for the Dibang multipurpose does not take into account impacts of the dam in Assam. The downstream impact assessment study does no assessment beyond Dibru-Saikhowa and whatever has been done is also very much inadequate.
No Public Hearing Held in Assam: Even though the Dibang multipurpose will have severe impacts in downstream Assam, there was no public hearing held for the project in Assam.
Mining for the Dibang Multipurpose will lead to Catastrophes: Mining of boulder, sand and other construction material for the Dibang multipurpose project will have very severe impacts on the river as well as on the local environment. The amount of boulder required for the construction of this project is 193 lakh cubic meter as stated in the project document. This is really astonishing figure and impact of such mining on the river bed and nearby areas will be catastrophic. The fragility of the Himalayan mountain range is not unknown to anyone and mining in such a sensitive hilly area will area will only increase the risk of landslide and disaster. The catastrophe of Uttarakhand floods is a clear example of this.
No Climate Change Assessment Impact of climate change on the project and impact of the project on the local climate. No attempt has been made to assess the impact of green house gas emissions from the reservoir of the dam which extends to 43 km.
No assessment impacts of peaking power operations Impacts Detail assessment of impacts of peaking power operation during non-monsoon months not done. Impacts on the flow characters of the river due to this dam, what will be the changes and how these will impact downstream areas.
No Assessment of Disaster Potential Impact of the project on disaster potential in the project area as well in the downstream including Assam due to construction and also operation at various stages, say on landslides, flash floods, etc.
No Assessment of Silt Flushing Impact of changing silt flows downstream from desilting chamber and from silt flushing in monsoon on the downstream areas not analyzed. A detail account of how the silt from the dam would be flushed out annually and what would be the impact of this in the downstream as well as on the geo morphology, erosion, stability of structures etc was not done.
What did the EAC say in 68th Meeting The EAC in its 68th meeting did not recommend environment clearance to the project and instead pointed out several issues in the EIA – EMP report. Some of the important issue pointed out by EAC are –
1. Attempts may be made to avoid submergence of huge area of rich forest land. It merits mention that due to the very high forest land submergence, forest clearance has not yet been accorded by FAC.
2. Environmental Flow in the diverted portion of about 1.2 km i.e. between dam and TWL of dam toe PH is to be reassessed and a suitable quantity is to be proposed for release as per extant norms. 4% flow as suggested was found to be inadequate.
3. Numbers of Fish species reported was found to be on lower side and NHPC was asked to verify this and report accurately.
4. Number of plant species reported also appeared to be on lower side and to be rechecked by NHPC.
5.At this altitude of the project (about 3000m), snow leopard should have been sighted. It may be erroneous to report that leopard was not found in the study area. Therefore, this may be relooked.
6. Study area in back water/ submergence is also to be extended for proper inventory of both flora, fauna/bio-diversity.
The impacts of the Dibang multipurpose project are going to severe on the river, people and overall ecology of Dibang river basin. But sad part is that no proper assessment of these impacts has been done till now. Looking back at the six years since the laying foundation stone for the project we reiterate what Forest Advisory Committee said about the project “ecological, environmental and social costs of diversion of such a vast tract of forest land, which is a major source of livelihood of the tribal population of the State, will far outweigh the benefits likely to accrue from the project.”
