AASU demands halting Mega dams in NE

Powerful student organisation AASU ( All Assam Students Union) has called for stopping mega dams in NE.

As per reports :
The All Assam Students’ Union (AASU) today demanded immediate steps to thrust aside the under-construction Lower Subansiri Hydroelectric Project (LSHEP) and also to shelve all the mega-dam hydel projects proposed in the NE region.

The demand of the students’ body came in the wake of the recommendations made by the eight-member expert committee that submitted its report on the issue to the authorities concerned on Tuesday. The students’ body also told newspersons at a press conference here today that its leaders would sit with the leaders of the Takam Mising Porin Kebang to chalk out the joint action plan in view of the expert committee’s report.

The expert committee observed that the present location of the LSHEP ‘was not appropriate,’ since the site is geologically and seismologically sensitive. Moreover, the seismic design parameter is not properly chosen for the project. The dam is designed to withstand an earthquake of magnitude 8, whereas the site and its adjacent areas have a recorded history of seismic events of magnitude 8.5 or even more, observed the expert committee.

The seismic design parameter considered for the project as 0.38 peak ground acceleration (pga) value for an 8.0 M earthquake at 10 km focal depth is largely inadequate. Consideration of the main boundary thrust (MBT) as source of such high magnitude earthquake which is about 15 km away from the dam site and not giving due consideration to the foothill trust (FHT), which is within the range of 3 km, can largely be considered as a serious drawback. The 1897 and 1950 great Assam earthquakes had their pga values exceeding 1.0g, observed the committee.

The committee recommended ‘not to construct the mega-dam (LSHEP dam) in the present site.’

It further recommended not to consider the Himalayan foothills, south of the geological MBT for any mega-hydropower project and also to redesign the LSHEP by sufficiently reducing its dam height and production capacity.

    Dear All:

    This is to inform you that Mr Badriuddin Ajmal, MP, who is Member on Parliamentary com on Climate Change and Global Warming / Standing Com in MoEF, is going to take a strong stand against the ill effects of the big dams that are being built against all the tech advisories without any considerations for the impact on the people/lives/environment of the NE Region. He has already expressed his strong views on this issue through media.

    Hon’ble MP is contemplating to draft a “Position Paper” on the big dam issue in the region. I would like to to request you to send us the copies of your earlier studies / memorandums / papers which can enlighten him about the concerns that you have successfully raised already. We are trying to ensure that as a member of Parliament from NER, he should also reflect the concerns that you have raised at all levels. The position paper will form a part of the formal deliberations of the Parliamentary Com on Climate Change and as the lone MP from this region on the com, we think we should use this channel to raise the issue at the highest level.

    Please send your input top this address by email , or send hard copies to Sri A R Barbhuiya, CEO to M B Ajmal, 1-3, South Avenue, New Delhi 110 001. Tel:011-23795357. FAX: 011-23795363

    Your early response will be highly appreciated.

    Thanking you,

    NB: As I am out of India, presently in Mauritius, I might not pick up your calls/ but I will be back in Guwahati by 13 Nov and in Barak Valley by 18 Nov/2010.
