Musings On Dust in Delhi
Many
studies on Delhi Pollution point to Road Dust or dust per se, as the major
culprit.
Swaminathan
Ankaleshwaria made an interesting, out-of-box suggestion about finding ways to gainfully
use massive quantities of dust, if mechanically swept by equipment expected in
operation by April 2016. He recommends finding
ways to convert the dust so collected to sand /aggregates for use in construction.
Such a solution
also has many attendant benefits, like lesser quarrying needs around Delhi.
But that
begs a question : where does the dust come from?
At another
level, a senior scientist told the High Court, that geography of Delhi is such
that it will have varying dust levels of dust, in different times of the year
and climatic conditions. Under some conditions it can be 10 times more than
permissible levels.
For
Geography, one should read, proximity to the great deserts of Rajasthan – the
Thar. There have been numerous studies on ‘desertification’ of Delhi- creeping
desert.
Hills of
Aravalli are the natural barriers: many have strongly recommended the ‘greening
of Aravalli” as a barrier to the dust that floats into Delhi. There is attendant benefit of cooling the
atmosphere and re-charging the ground water of Gurgaon and environs.
Dusty matter.. Glad that somebody if talking sense.. Not blaming it all to motor vehicles..
ReplyDeleteThanks Arun,
ReplyDeleteI suspect the politicians use few catchy dimensions of a problem / issue to grab the attention of their 'subjects' (read US). And then get carried away by their own "advertising"
