Harvesting rainwater effectively
An innovative project makes rainwater harvesting easier and more effective in certain areas of Mewat village with increased groundwater salinity. Posted on 15 Feb, 2018 01:25 PM

One of the major causes of deterioration of water quality is the increase in overall salinity. Total hardness and the presence of materials like fluoride, nitrate, iron, arsenic, and toxic metal ions determine salinity levels in groundwater. With the demand for groundwater growing rapidly, its exploitation is also accelerating which causes depletion.

The innovation was introduced in a government school building in Untka village located in Mewat district of Haryana.

Can grey and green coexist on urban landscape?
As cities spread wide, grey infrastructure projects flout green norms to provide affordable housing for all. Posted on 31 Aug, 2017 03:03 PM

Far in the distance, towards the edge of Noida and Greater Noida flows the Hindon river amidst clusters of modern highrise buildings. A few years ago, the landscape here was more countrified and quite distinct from the low rise neghbourhoods of Delhi dotted with its numerous parks and abundant institutional spaces. 

Building bye-laws mandate that builders adhere to environmental norms and install energy-saving mechanisms like solar installations, water harvesting and waste recycling methods.

Porous pavements to save concrete jungles!
Cities may not be able to lessen their 'concrete footprint', which prevents groundwater from entering the soil but maybe more city spaces can use porous surfacing to deal with this problem. Posted on 08 Jan, 2015 10:20 PM

Despite its shrinking greens, Delhi has significant tree diversity. Pradip Krishen, a naturalist, author and filmmaker, identifies around 250 tree species in the concrete jungle, in his book titled ‘Trees of Delhi’ published in 2007. But these trees do not have the breathing room they need as the Public Works Department's (PWD) pavement tiling projects enclose trees completely in concrete.
