WHY POLAVARAM DAM IS BOUND TO COLLAPSE WHILE THE BARRAGES PROJECT WILL BE SAFE

HOW TO GET POLAVARAM PROJECT MATERIALISED BY SECURING ENVIRONMENTAL CLEARANCE UNDER THE NEW GUIDELINES OF 2006?

PUBLIC HEARING FOR ENVIRONMENTAL CLEARANCE OF  POLAVARAM  PROJECTS

(Published in the Gazette of India, Extraordinary, Part-II, and Section 3, Sub-section (ii)
MINISTRY OF ENVIRONMENT AND FORESTS   New Delhi 14th September, 2006)

At present there was a controversy on holding public hearing for embankments project estimated at Rs.700 crores as a supplementary project of the Polavaram dam.  The AP Chief Minister is declaring that AP State cannot hold this public hearing for their Polavaram project in Orissa and Chattisgarh.  The Orissa and Chattisgarh state Governments are refusing to hold public hearing on this project because they have filed cases in the supreme Court against the Polavaram dam and hence it may be subjudice.  But the Central Government Ministry of Environment and Forest issued a notice to the AP State Government why they are going ahead with the Polavaram dam project without holding public hearings on the embankments project in Orissa and Chattisgarh.  In the normal conditions the AP State Government should have maintained cordial relations with Orissa and Chattisgarh on this project for securing their approval for the main dam project and also this supplementary embankments project.  Similarly they require the consent of these upper states even for the 960 MW hydro-power project which is part of the Polavaram dam project.  Now the AP State Government has taken a posture of confrontation with the upper states and is demanding the Union Government to use its good offices to convince the upper states to the construction of Polvaram dam project estimated at Rs.16,000 crores. 

 1.   Environmental clearance for Forests given by Union Ministry is self defeating:
Catch-22 situation is created by the Union Ministry of Environment and Forests by according clearance for 3700 ha. of forest land for Polavaram Dam.This is a meaningless as well as a mischievous action taken by the Government . Even the Orissa High Court Judgement of April 2006 directs the AP State Government to go ahead with Polavaram project without causing any submersion of villages, forest lands and displacement of tribals in Orissa.  This judgement is like the judgement in the Shakespearean drama of Merchant of Venice where the judge asks the plaintiff a Jewis money lender, Mr.Shylock to take his pound of flesh from the chest of the defendant merchant who failed to repay the debt in time. This judgement directs Shylock to cut his pound of flesh without a drop of blood, it means a Catch-22 situation, or a self-defeating course of action: or a paradoxical condition or set of circumstances that preclude any attempt to achieve the goal without getting engulfed by the disabling conditions.  you cannot have your pound of flesh without a drop of blood. One cannot have the cake and eat it too. Hence the action of the Central Government  Ministries in giving clearances to Polavaram project is an act of cheating the people of India at a time when the people, state officials and other experts have to  protect the Environment under Article 51 A(g) of the constitution of  India.
2.  Environmental clearance given by Union Ministry of Environment in October 2005 is based on insufficient and false information provided in the EIA report by AP State :
According to the Environmental Protection Act 1986 and its regulations the AP State Government engineers, officials of Ministries like Finance, Environment and Forests and Pollution Control Board are expected to know that the Environmental Impact Assessment(EIA) Report for Polavaram must contain not only Risk Analysis (RA) and Dam Break Analysis (DBA) reports but also the Emergency Action Plan (EAP)and Environmental management plan[EMP] reports in detail so that the costs of remedial actions to be taken in case of a potential dam burst will have to be included in the original project budget so that the genuine cost benefit ratio can be scientifically deduced on the basis of the alternate project proposals which confer the similar economic benefits as contemplated by the original project.  Similarly the various expert committee members  of various Ministries in the Union Government like Finance, Agriculture, Water Resources, Planning Commission, Central Water Commission, environment and Forest and Tribal Affairs must also scrutinise the EIA report including RA, DBA,EAP and EMP reports. 
 Unfortunately due to lack of accountability among all the concerned engineers, Secretaries and officials of the AP State and Union Government Ministries most of the permissions  for Polavaram dam project were sanctioned blindly with the result that the people of Andhra Pradesh were mislead by both the Union Government officials as well as state Government officials on the safety, economics and sustainable development aspects of the project.  Hence people in the state are looking at the project just as the traditional blind men looked at the elephant in the old Chinese story.  Today the people in Malkangiri disrict of Orissa are agitating against the Polavaram project on the ground that the damaging impacts of this project will be felt in 18 villages including displacement of more than 20,000 people, mostly tribals and more than 1.5 lakh acres of forest lands to be inundated due to the proposed Polavaram dam.  The Orissa people are questioning the Central Government Why the Union government Ministries have blindly given permissions for an interstate projects like Polavaram without taking into consideration the views of the neighbouring states of Orissa and Chattisgarh as per rules and regulations. 
 The dam break analysis reports prepared for Polavaram dam by the AP State Government and scrutinised by several Ministries of the Union Government are blind to realise the damaging impacts such as providing watery grave to 50 lakhs of people downstream of the dam in case of an inevitable collapse of the dam for several reasons and the consequential economic loss of more than 1 lakh crores of rupees which makes the country poorer and thereby promotes poverty on a large scale including promotion of unemployment and inflation which are not certainly the main objectives of the proposed project.   The people of India have a right to life, right to health, right to employment and all these rights are going to be adversely affected by this dam. 
Moreover EIA report was prepared on the basis of the Probable Maximum Flood of 36 lakh cusecs which is a serious underestimate for a massive catchment area of a major river like Godavari.  In view of the enormous floods received in Godavari in  August 2006  the Central Water Commission opened their eyes and made realistic calculations for estimating the Probable Maximum Flood and placed it at 49.5 lakh cusecs or 50 lakh cusecs. Since the Environmental clearance for the project was already obtained based on 36 lakh cusecs flood the calculations made for dam break analysis and for demarcation of backwater levels for identifying the areas of submersion in the upstream of the dam will be highly unrealistic and consequently the estimated cost of the project would be underestimated.
3.   Legal methods of decision making for Environmental clearances for major project:
(a)  Precautionary principle : Whenever legal judgments are to be pronounced on the acceptability or rejection of any development projects including irrigation projects an environmental impact assessment including the social impact assessments have to be made and if there are grey areas regarding the environmental backlashes on crucial natural resources conservation including species of plants, animals and human beings a decision has to be based on the precautionary principle which has been accepted by the world nations at the Rio-De-Janeiro conference on Human environment (1992).  One of the reputed Judges of the Supreme court of New South Wales, Australia , Justice Paul Stein gave his considered opinion on how to take decisions on projects intended for sustainable development. (Quoted from Environmental Law Review Journal of UK Volume-2, 2000)
Use Of The Precautionary Principle For Development Projects
Principle 15 of the Rio Declaration states:
“In order to protect the environment, the precautionary approach shall be widely applied by states according to their capabilities. Where there are threats of serious or irreversible damage, lack of full scientific certainty shall not be used as a reason for postponing cost-effective measures to prevent environmental degradation”.
In the Australian context definition adopted in legislation has been:
“Where there are threats of serious or irreversible environmental damage, lack of full scientific certainty should not be used as a reason for postponing measures to prevent environmental degradation. In the application of the precautionary principle, public and private decisions should be guided by:
(i) careful evaluation to avoid, wherever practicable, serious or irreversible damage to theenvironment; and
(ii) an assessment of the risk-weighted consequences of various options”.
The precautionary principle has the potential for positive gains for the environment and national development  if applied appropriately by decision-makers. Along with the principles of ecologically sustainable development (ESD), this principle has the capacity to be a key tool for  environmental protection and even improvement. The converse of the non-application of this precautionary principle, where the circumstances demand it, can surely lead to an irreversible deterioration in the environment and loss of ecosystems and human environmental assets.
To deal with some cases of application of this principle we can quote the “ Pakistani case of Zia v WAPDA in which the State Authority was constructing an electrical grid station in a residential area.  The petitioners, local residents alleged that the electromagnetic field created by the high voltage transmission lines would pose a serious health hazard. Article 9 of the Pakistani Constitution states that ‘no person shall be deprived of life or liberty save in accordance with law’.  Article 14 of the constitution  provides that ‘the dignity of man and the privacy of the home shall be inviolable’. Article 184(3) provides for public interest litigation. Where the ‘life’ of citizens is degraded, the quality of life is adversely affected and health hazards are created, affecting a large number of people, the Supreme Court may grant relief to the extent of issuing injunctions on factories which create and promote environmental degradation. The Court held that existing scientific evidence regarding the possibility of adverse biological effects on people from exposure, as well as the possibility of reducing or eliminating such effects, was inconclusive. In responding to such scientific uncertainty the Court applied the precautionary principle for the benefit of the public.
In another case of Andhra Pradesh Pollution Control Board v Nayudu,  the Supreme Court of India considered a petition claiming that certain hazardous industries proposed to be established without the necessary certificate from the Pollution Control Board could not proceed to operate such polluting industries . M. Jagannadha Rao J elaborated the difficulties faced by environmental courts in dealing with scientific data. He quoted articles by Lords Woolf and Carnworth on the desirability of specialist environmental courts. In particular, his Honour discussed the status and application of the precautionary principle.
His Honour said:
“The ‘uncertainty’ of scientific proof and its changing frontiers from time to time has led to great changes in environment concepts during the period between the Stockholm Conference of 1972 and the Rio Conference of 1992. In Vellore Citizens’ Welfare Forum v Union of India and others, 1995 (5) SCC 647, a three Judge Bench of this Court referred to these changes, to the ‘precautionary principle’ and the new concept of ‘burden of proof’ in environmental matters.”
Kuldip Singh J after quoting  the principles evolved in various international Conferences and to the concept of ‘Sustainable Development’, asserted that the Precautionary Principle, the Polluter-Pays Principle and the special concept of Onus of Proof have now emerged and govern the law in India too, as is clear from Articles 47, 48-A and 51-A(g) of Indian Constitution . . .
The Court also elaborated on  the issue of burden of proof in cases involving the application of the precautionary principle: “ The precautionary principle suggested that where there is an identifiable risk of serious or irreversible harm, including, for example, extinction of species, widespread toxic pollution in major threats to essential ecological processes, it may be appropriate to place the burden of proof on the person or entity proposing the activity that is potentially harmful to the environment.”
 Freestone, Legal Expert of the World Bank recognizes the emergence of the precautionary  principle as one of the most important developments of the new era. The precautionary principle has become part of international customary law. How the rhetoric of the principle can be operationalised is one of the challenges for the first decade of the 21st century.  This precautionary principle is not absolute nor extreme in its scope. It does not halt development  until the science is clear. But it changes  the underlying presumption from freedom of exploitation to one of conservation. One thing is clear—the precautionary principle is here to stay, with or without legislative support.  However Decision-makers and courts will not be able to avoid it or merely pay lip-service to it. Surely the courts will be required to review its application and attempt to apply it. Courts have to evaluate the principle and its place in environmental decision-making and particularly with regard to major irrigation projects whose viability is questioned in public interest.
In the Polavaram project the scientific and technical experts of the Union Ministry of Water Resources located in the National Institute of Hydrology, Roorkee clearly stated in their report that several dams have collapsed and if the proposed earth and rockfill dam at Polavaram were to fail for one reason or the other the consequential wall of flood water will wipe out of existing thousands of people living downstream of the dam.  Hence there is sufficient scientific proof  and the precautionary principle has to be applied in this case and alternate methods of achieving the same economic goals can be obtained by converting the killer Polavaram dam into multiple barrages which are safe and beneficial. 
(b)  Law of Comparative Consequences: In the United States whenever there is a conflict in decision making with regard to a major development projects a comprehensive environmental impact analysis report is prepared including emergency response systems and disaster management systems.  After considering the advantages and disadvantages of the proposed project a decision is ultimately taken on the basis of the law of comparative consequences.  If expert “X” presents a particular  view that the positive contributions of the project work out to certain amount of costs  and expert “Y” presents another view involving the disastrous consequence of the project resulting in negative impacts of the project amounting to certain amount of costs,  then the decision makers will consider both points of view.  The decision makers compare the relative costs of implementation of the project and non-implementation of project and  ultimately decide on the choice which presents least cost to the community.  Otherwise a modified project which can achieve more or less the same economic goals of development will be taken up in the interests of ensuring sustainable development of the community on the plea that development also forms part of the Right to life and Right to livelihood as the project not only provides employment potential but also secures economic and social development resulting in a better quality of life.  In this context the people of India in general and the people of Andhra Pradesh in particular must weigh the costs and benefits of the proposals made by the State Government for construction of Polavaram dam and alternate proposals of constructing multiple barrages in place of the dam.
4.     Union Ministry of Environment shall reject clearance for Polavaram dam project because Embankments intended for flood control are inevitably  bound to fail :
By furnishing wrong information and without conducting public hearing on the EIA report in the areas likely to be submerged in Motu and Konta taluks of Orissa and Chattisgarh, the Environmental clearance obtained cannot be strictly considered to be legal.  Further the AP State Government submitted a second EIA report estimated at Rs.700 crores for construction of embankments to protect the areas likely to be submerged in the Sileru and Sabari catchments in Orissa for a length of about 30km  and even for this project also there was no public hearing conducted in the upper states and the state Government has not taken the consents of the upper states for construction of these embankments.  Thus the clearances taken for this project from the various Ministries of the Union Government such as Water Resources, and Tribal Affairs and Planning Commission are based upon a misleading and incomplete environmental   clearance obtained from the Union Ministry of Environment.
Embankment dams can also fail due to Bombing by terrorist agencies or enemy countries as Britishers dropped Bombs over the German dams and destoyed them to cause damages to the people and properties
 see the web site for more details on Bombing over Dams: http://en.wikipedia.org/wiki/Operation_Chastise
 (a)  False view of Government agencies on Embankments to protect people from floods:  The contention of the Central Water commission that the lands in Chattisgarh and Orissa can be protected from the floods due to Polavaram dam construction is based on false assumptions. 
The Central Water Commission is misleading  the courts and the state and central Governments that submersion of lands in the Sabari river basin and Sileru river basins in Chattisgarh and Orissa can be protected by Andhra Pradesh by constructing embankments along the river courses.  This false assurance to the states and the Bachawat Tribunal was also based upon the immature views of the Central Water Commission and the Union Ministry of Water Resources provided during the time of the interstate agreement on Polavaram project in April 1980.
 In fact the embankments constructed by the AP State Government along the banks of the Krishna river to protect the temple town of Alampur in Mahaboobnagar district have miserably failed to prevent the peak floods that ravaged havoc during October, 2009.  Flood embankments have miserably failed to protect the people and their properties in several river basins since a number of years in the states of Bihar, Uttar Pradesh, Orissa and Bangladesh.  The evidence of such failures can be found from the following websites.
The former secretary for the Union Ministry of Water Resources and an International expert on Water Resources management clearly establishes that  embankments  cannot ensure safety of people and their properties from serious floods in the rivers and for several reasons they cause more misery to the people.  The following is an extract of his article on the failure of flood embankments.
(b)   Expert views on   failure of embankments to control floods in rivers :
The following are the views of the Water Resources expert Sri.RAMASWAMY IYER, Former Secretary, Union Ministry of Water Resources, Govt. of India, on the futility of embankments to protect people and their properties from floods.
“From time to time there are floods in various parts of this country, and sometimes they are very heavy and cause much loss of life, livelihoods and property. Whenever this happens, it generates a strong  feeling that something should be done about this problem. Starting from the proposition that the problem, i e, floods, should not be allowed to happen again, administrators and engineers decide that the river needs to be controlled, and come up with proposals for embankments and dams. Is there anything wrong in that reasoning? To answer that question, we must first distinguish between avoidable and unavoidable floods. When Delhi or Mumbai gets heavily flooded with the first monsoon showers, the cause is inadequate or badly designed or poorly maintained or carelessly blocked drainage systems, or the ill-considered diversion of natural drainage channels. These are floods caused by human error or failure or negligence or folly, and are entirely avoidable.
Floods are also sometimes caused by bad dam management, and these too are manmade. The Orissa floods of September 2008 seem to fall into this category. When we describe a flood as man-made, the
implication is that appropriate measures at an earlier stage could have averted or minimised the flood.
That does not apply to periodical river floods. These are natural phenomena arising from various factors. There could be seasonal floods because of heavy and continuous rains in the monsoon period; flash floods from cloud-bursts; floods resulting from the sudden release of waters held up by blockages caused by landslides in the mountains; and so on. These floods cannot be prevented. They have occurred before and will occur again. They can be of varying magnitudes and intensities, and the regular floods, i e, those other than freak events, are classified by probability of recurrence (once in 20 or 100 or 1,000 or 10,000 years). When the flood-waters come, the river needs space to spread and accommodate them. That space is known as the natural flood-plain of the river. If we occupy the flood-plain or build structures on it, or try to jacket the river within narrow confines, we are asking for trouble.
Embankments: Wrong Thinking If habitations or structures or activities have already – unwisely – come up in areas that are likely to be flooded, and the option of moving them to other areas is not available, some degree of protection through bunds or embankments may be inescapable. However, it seems clear that wisdom lies in avoiding such situations. Generally speaking, it is preferable to  let the river flow and have its space, and refrain from constraining it through embankments. There are many reasons for that statement. Assuming that an embankment is properly maintained – a questionable assumption – it might still give way in an exceptionally heavy flood. That is the nature of embankments. Embankments tend to fail and have to be rebuilt repeatedly at enormous cost, often a multiple of the
original cost of building them. Even if they do not break down, they might still cause various problems. The engineering assumption in the Kosi case and elsewhere was that the jacketing of the river would increase the velocity of the waters leading to a scouring of the river-bed, and that the river would find extra space for itself.
Experience has not borne out that assumption. The jacketed river might proceed to attack areas further downstream. The embankment that prevents the river from spreading also blocks drainage from either
side into the river, leading to the emergence  of water logging and even flooding in the areas “protected” by the embankment (as already mentioned). Sluices are no answer because the deposition of silt leads to a rise in the level of the river-bed, with the river flowing above the level of the ground on either side: instead of waters from outside flowing into the river through the sluices, the river waters will tend to flow out. While it might be possible to cite some specific instances in which embankments have done some good without doing much harm, they are in many cases remedies worse than the disease.”
5.  Polavaram dam is bound to collapse due to several reasons:
Several people think that dams do not fail as they do not know that storage of water behind any dam is a source of hazard of some magnitude depending upon the amount of water stored and the type of structure used for storage.  Several people consider that since the Nagarjuna Sagar dam and Srisailam dam have not failed during the peak floods of 26.5 lakh cusecs in Krishna river that occurred in October 2009 the Polavaram dam also would not fail. This is a wrong concept because the Nagarjuna Sagar dam is a massonary dam and the Srisailam dam is a concrete dam while the proposed Polvaram dam is an earth and rockfill dam
(a) Earthen dams have more chances to collapse due to several reasons: 
 It is good to start construction of Polavaram earthen dam with a firm conviction that it would be built very strongly and would never break due to any quality reasons. If. the recent experiences on the earthen dam constructed in the State are any guide, one cannot be so sure of this conviction. In fact, all the earth dams will be constructed only with such convictions. But, we see different results all over the world. The Earthen dams of two medium irrigation projects (namely Gundlavagu Project and Palem Vagu Project,) constructed during the past four years in the State, have breached even without the designed maximum flood occurring. During August.2010 the Subbareddy Sagar Medium Irrigation project in Prattipadu Mandal of East Godavari district collapsed due to excessive floods after 12 years of its construction.  


 The Palemvagu dam in Khammam district 
which breached on Monday. Tuesday, Aug 05, 2008
http://www.hindu.com/2008/08/05/stories/2008080555900100.htm  (Palemvagu)
Kadem dam in Godavari basin also collapsed in 1958. There are innumerable  similar examples of dam breaks throughout the world, especially with earthen dams, well before the occurrence of P.M.F. The recent  one in India was the Morvi Earth Dam (Gujarat) breach, which killed about  15,000 people. Earthen dams can also break due to reasons other than quality. That is why the recent international recommendation is to avoid, construction of earthen dams in the close vicinity of thickly populated areas. Polavaram earthen dam sits just upstream of an extremely thick populated area. Even though the Polavaram earthen dam  is designed for a P.M.F. of 50 lakh cusecs,  the possibility of dam break cannot be ruled out (vide UN & ICOLD Guidelines on E.I.A.).  Infact several dams failed in India and the details are presented in the Annexed table below.
(b) Why Polavaram dam is bound to collapse while the barrages project will be safe:   
http://tshivajirao.blogspot.com/2010/06/why-inevitable-collapse-of-polavaram.html             
There is an argument that when a flood of 89 lakh cusecs occurs in the river, the areas on either side of the Godavari river will any way get flooded (with or without the dam), and the population will get effected, since the protective flood banks are designed only for a maximum discharge of 36 lakh cusecs. But, there is a difference between a dam break and a natural flood increase. In the case of a Polavaram dam break, the stored water of 194 TMC along with the huge flood of 89 lakh cusecs will flow down below, as a gigantic wave, similar to the Tsunami wave. People will have no time to leave their habitats. If such a break occurs during the nights, 46.15 lakh people will have a watery grave within some hours of occurring of the dam break. With regard to a natural occurrence of 89 lakh cusecs, this would occur gradually over a number of days and people will have time to observe the same, vacate their habitations, and move to the designated higher grounds. It has happened similarly in Krishna Delta during the extraordinary floods that occurred in Krishna river in October, 2009. In other words the increase in water levels does not happen suddenly in a few hours (unlike the dam burst wave).  Earthen dams are susceptible for breaks (e.g. Kaddam Dam) and Polavaram case can therefore be considered as a calamity “waiting to happen”.
This alternative proposal is suggested primarily in the interest of  population  residing in the Godavari delta, especially in the light of the recent occurrence of Krishna huge flood of 2.7 times the ever observed maximum flood. As a matter of fact, this alternative proposal will have to be strongly favoured by the Godavari delta people instead of opposing it, since this gives all the benefits of. the earlier "Dam proposal" without any risk to their lives in future. This apprehension may be due to information gap about the alternative proposal. In the case of the alternative barrage proposal the huge incoming flood of 89 lakh cusecs will pass down the structure, as it is, without any obstruction, and hence there is no need to do any 'dam break analysis' (as there is no dam).
6) Objections raised by Orissa State Government against Polavaram Dam
Extracts from: http://www.dowrorissa.gov.in/AnnualReport/WR_AR08-09.pdf [pages 94-96]
Orissa has been frequently raising many objections on clearences given to Polavaram dam by various ministries of the Union Government and the Central Water Commission]CWC]
a) Improper Permission of CWC to A.P.State to construct Embankments on Rivers in Orissa to avoid submersion of Lands due to construction of Polavaram Dam
The Orissa State Government filed a case in the Supreme Court against the Government of Andhra Pradesh under Art 131 of the Indian Constitution on 09.10.2007 with several prayers including the one on construction of Embankments to avoid submersion of lands in Orissa due to Polavaram Dam and “to declare the permission of Central Water Commission vide its letter No.6/125/2007 PAC(S) dated.11.04.2007 to construct embankments as null and void as it is not based on any technical data. CWC has not done any investigation. Further, no data has been supplied to Plaintiff State of Orissa by CWC before giving its decision.”
b) Demand for implementation of 1978 Agreement under Bachawat Award ?
In the inter-state meeting held on 15.12.78, it was decided to go for the construction of Polavaram project in such a manner that maximum submergence in Orissa territory should not exceed RL 150ft at Konta/Motu due to all effects including back water effect.
The Godavari Water Dispute Tribunal (GWDT)passed its final order during April 1980.
Clause(VI) of the order states that the Polavaram project shall be cleared by the Central Water
Commission (CWC) as expeditiously as possible for MWL/FRL 150ft. The matter of design and its operation was left to CWC keeping in view all the agreements and change in operation schedule to be done in consultation with co-basin states. The design aspect was left entirely to CWC by GWDT
c )Validity of Bachawat Award being Questioned ?
While the the issue of submergence in Orissa remain unresolved. The Ministry of Environment& Forest, Government of India have granted environmental clearance to the project on 25.10.2005 based on design flood of 36 lakh cusecs. In the meanwhile, the design flood of the project has been revised by CWC to the order of 50 lakh cusecs. As such, the environmental clearance given to this project can not be treated as valid and has to be revoked as the Environmental clearance was given basing on design flood of 36 lakh cusecs.
d) A.P.State frequently changes Estimates on Submersion of Lands in Orissa
During the inter-state meeting held on 26.2.1997,Government of Andhra Pradesh intimated that at 36 lakh cusecs design flood the water level may go up to RL 182 feet due to back water effect. As a result 7 villages (1026 ha of land) in Orissa territory are likely to be affected.
Further Govt. of Andhra Pradesh intimated during March 2001 that 10 villages and 2119.38ha. of land were likely to be affected in Orissa territory. 648.05 ha. of land would be submerged at RL 150 ft. which includes 102.16 ha. of reserve forest in Orissa territory. These values are based on the remote sensing data.

If Polavaram project is bound to
collapse, do you mean the engineers who planned the design and started the construction work of Polavaram project are fools.You are advocating to construct alternative barrages in place of Polavaram project to reduce submersion.But by construction of alternative barrages only 2.5 lakh acres of land could be irrigated that too by lift irrigation only. Uttarandhra sujala sravanthi and
Indirasagar lift irrigation projects should be cancelled.Power
generation will be reduce.There
will not be diversion of Godavari
waters in to Krishna river.There
will not be stabilization of
Godavari delta ayacut which is
going to suffer by construction of
huge lift irrigation projects in
Telangana.So it is better not to
construct the project instead of
constructing alternative barrages
and wasting money.
