Stop the Illegal Construction of Kanhar Dam

There is an indefinite demonstration by more than 5,000 tribals and local villagers at the project site since 5th December, 2014 when the construction started at river bed near confluence of river Pagan and river Kanhar close to Sugawaman village in Dudhi tehsil of District Sonebhadra.

Kanhar Dam is one of those projects which is an example of how so called developments worsen the situation for the people and environment. The project conceived 37 years ago has been in abeyance since last 25 years. With the latest inauguration of construction of the dam on 5th December, 2014 after a span of 25 years without a fresh proper cost benefit analysis (CBA), any environment impact assessment (EIA) or Social Impact Assessment (SIA) ever, the commencement of project activities is against the law and natural justice.

As per offiial records with Ministry of Environment, Forests and Climate Change, the project has 'Environment Clearance' of 1980 which is more than 34 years old and invalid. Hence, the project requires a fresh 'Environment Clearance' under EIA Notification, 2006 and all the studies done again to assess whether the project is viable or not with respect to the present scenario.

The dam will submerge more than 4,000 Hectares of land in which not only lakhs of trees will be affected, but nearly 10,000 families (many of which are tribals) will be displaced. The project do not have a 'Forest Clearance' under Forest (Conservation) Act, 1980.  As per a recent newspaper report, the affected families are 60,000 from 80 villages across Chhattisgarh and Uttar Pradesh

It is further observed that despite the order of National Green Tribunal dated 24th December, 2014 in which it was clearly stated that the Irrigation Department, U.P. will not conduct any construction activity if they do not have Environment Clearance and Forest Clearance under law, the construction is still going on in blatant violation of the court order.

Major Issues related to the Kanhar dam is summarised below:

1. LARGE SOCIAL IMPLICATION:  Nearly 10,000 tribal families are going to be affected directly who will lose their ancestral land permanently. Gram Sabhas of the project affected villages has already passed a consensus against the project and submitted the same to the State Govt.

2. LOSS OF DENSE FORESTS: The Renukoot Forest Division is one of the dense forests of Sonebhadra with tree density of 652 per hectare as per data obtained from a forest clearance application involving the same forest division. The Kanhar project document shows 4439.294 Ha of land categorized as ‘Forest and others’. In such case, lakhs of trees will be affected by this project which would cause significant impact on environment, wildlife and livelihood of tribals.

3. LOSS OF RICH BIODIVERSITY: Vindhyan mountain range is known for the wildlife and rich diversity of medicinal plants which are inherently linked with tribal culture. Scientific Publications shows there are at least 105 species of medicinal plants in the region which are extensively used as traditional treatment by tribal people. The project will endanger the remaining few patches of forests which are not only the last few remaining patches of rich biodiversity but refuge to several wild animals in this heavily disturbed landscape. Conversations with the villagers will reveal presence of mammals like Sloth Bear, Leopard, Blackbuck, Chinkara, Jackal etc and several reptiles including Bengal monitor and snake species in these forests. The submergence area falling in Chhattisgarh is reported to be an elephant corridor.

4. IMMENSE LOSS TO ECOLOGY OF RIVER SON AND GANGA: Kanhar is a major tributary of River Sone which forms an important catchment of Ganga River Basin. After construction of Rihand Dam and Bansagar dam and various other water abstraction structures owing to number of industries in the region because of availability of coal mines-River Sone is one of the most exploited system which has lost its riverine characteristics. Central Inland Fisheries Research Institute reported disappearance of 20 fish species from Sone in the time span between 1976 and 2011 which is attributed to increased abstraction of water from the Sone river system. The report clearly states that ‘damming of rivers or tributaries is the root cause of river obstructions causing severe modifications and perturbations to the river flow, velocity, depth, substratum, pools, ecology and fish habitat’. There is reporting of 14 exotic alien species in the river. The report claims that the river Sone is in critically modified (class F) condition with discharge of mere 5.16% of Mean Annual Runoff (MAR) and it will require at least 34.2% of MAR to bring it to slightly modified class (class B). In such a scenario, damming of 5200 km2 of the total catchment of 5,654 km2 of river Kanhar will be disastrous for the river Sone depriving it of the major share of the present water availability. As Sone river system forms an important catchment of River Ganga, the impact on ecology of River Ganga is undeniable.

5. CONTRIBUTION TO CLIMATE CHANGE: We will lose lakhs of trees which would act as carbon-absorption system. To double the problem, the carbon which is locked in the forests will be released to atmosphere when these trees will be felled. While Carbon Dioxide is released from aerobic decomposition of plants, the anaerobic decomposition of organic matters will release methane which is 24 times more potential GHG than Carbon Dioxide. There is global evidence which support production of GHGs in dams, the quantity of which varies on several parameters like climatic conditions, water depth, water fluctuation, area of submergence, dissolved oxygen etc. Emission of GHGs like Methane is known for a positive feedback trigger which would lead to more absorption of heat causing further rise in temperature, thus increasing the rate of anaerobic decay in the reservoirs and release of more Methane.

6. LACK OF PROPER COST BENEFIT ANALYSIS: The cost benefit ratio of such projects are calculated on investment and direct benefits from the projects with consideration of impact of project on people & ecosystem, which are often underestimated and excluding socio-cultural costs and cost of a healthy environment and cost of services provided by the river, forest and other ecosystems. The monetary value of the impacts such as on forests, biodiversity, fishing, non-use values, public money spent on infrastructures, cultural loss and other negative impacts are not considered at all.

7. LACK OF OPTIONS ASSESSMENT: There has been no options assessment as to establish that this proposed dam is the best option for water resources development in the Kanhar/ Sone basin.

There is no justification for the project. There has not even been an application of mind if the project is beneficial to the people and society. There is not even any impact assessment, nor any democratic decision making process. A huge amount of public money is already spent on development of schools, roads, hospitals, houses etc in the area, which will be lost permanently by this project. At the time, when this project was incepted in 1976 the environment and social scenario of the country and this region was very different from what it is today. River Sone was not in critically modified state, Forests of Sonebhadra and adjoining regions were still intact, human population was lesser, technology was not so advanced, science of climate change was not fully understood and the need of protection of environment was not felt or required as it is today. In 1976, protection of rivers was not a primary concern as the problems were not evident as it is today. In such scenario furthering such abandoned projects shows poor understanding of environment and insensitive attitude by the policy makers. It is thus important to undertake a proper cost-benefit analysis, a fresh Environment Impact Assessment and Social Impact Assessment, conduct proper options assessment to understand the implications of this project on the ecological balance and people keeping into account the present scenario. Such studies should undergo a detailed scrutiny and public consultation process.
