DAM BUILDING MUST BE HALTED FOR A SAFE AND SECURE WORLD

Guest Blog by Manoj Misra

Rivers in different parts of the world have been dammed to fulfill human needs like water for irrigation, industries and domestic supplies. Then there are dams that have been raised to control floods or to produce electricity.

These have often been celebrated as human victory over nature, glorified as engineering marvel and claimed variously as highest, longest etc as a matter of national pride.

But rarely has there been a holistic assessment or appreciation of what a dam does to the natural entity called river and its adverse impacts on all the associated life forms, including humans.

DRP News Bulletin 12 June 2017 (Rain Bearing Clouds Thinning Out Over India: IMD Study)

A recent IMD study has found that rain-bearing clouds have been thinning out across the country over the last 50 years. The study, published in the IMD journal Mausam, shows that between 1960 and 2010, annual mean low cloud cover (responsible for the bulk of the rainfall) over India has been decreasing by 0.45% per decade on an average.

According to the study, the number of rainy days is also declining during the monsoon season at an average rate of 0.23 days for every decade. This means that the country has lost approximately one rainy day over the last five decades. The study found that while the number of rainy days is decreasing, there is not much change in the total amount of rainfall. This shows a trend towards shorter, heavier bursts of rain.

That is bad news, because heavier raindrops can dislodge wheat and rice grains from their stalks while on the farm. It also means rainwater flows down a slope that much faster instead of percolating underground.

Meanwhile, a new NASA study has warned  the amount of rainfall in the Earth’s tropical regions will significantly increase as the planet continues to warm. As per study rainfall is not related just to the clouds that are available to make rain but also to Earth’s “energy budget” — incoming energy from the Sun compared to outgoing heat energy. High-altitude tropical clouds trap heat in the atmosphere. If there are fewer of these clouds in the future, the tropical atmosphere will cool.

DRP News Bulletin 16 Jan. 2017 (MoEF’s Expert Committee Shows Anti-People, Anti-Environment Biases)

EAC against entertaining ‘anti-development’ representations The expert appraisal committee (EAC) on river valley and hydel projects of the Union Environment Ministry has decided “not to take any cognizance of such representations” received by its members. In its Dec. 30, 2016 meeting, the committee concluded that once a project proposal reaches the EAC for appraisal, it has crossed the stage of public consultation and “the EAC should not go back in time, and should not reopen it, by entertaining unsubstantiated representations received from the people”. 

The EAC noted that in case of any clarification regarding action taken on such representations under the RTI Act, the EAC prescribed that a standard reply “action has been taken in accordance with the decisions taken in the 1st meeting of the EAC for River Valley and HEP on 30.12.2016” should suffice. “It was also felt that many of the objections raised are repetitive. Many such kind of representations have an anti-development attitude so that the projects are kept on hold or delayed. This has financial implications to the developers in particular and to the nation in general.

The committee emphasized that relevant ministries scrutinised every aspect of a project and proposed it for final appraisal only when all details were in place. If not satisfied that public consultation had been completed properly, the EAC said it could ask the project promoter to do the needful. The committee also made allowance for representations with “new points” and “grave consequences” on which comments from project proponents could be sought. The EAC considered 13 projects in its December 30 meeting and cleared eight of them.

Environmental activists, however, pointed out the impracticality of the contention that representations should be restricted to the 30-day public consultation window. Sripad Dharmadhikari also, in his blog has mentions various reasons to counter the EAC’s suspicious justifications. He also says that the fact that a body which is supposed to represent the environmental perspective displays such an attitude is the biggest critique of the EAC and the environmental clearance process that it is a part of. The newly constituted MOEF’s EAC on River Valley Projects has in their very first meeting shown anti people, anti democratic and anti environment attitude.
