New Delhi: The national Capital Territory of Delhi is to have a wall of nearly 31 lakh native trees encircling it soon to shield it from frequent dust storms coming from Rajasthan and enveloping and choking it.
A senior official of the Union Ministry of Forest, Environment and Climate Change said that various agencies of the Union and Delhi governments have already begun the work of planting nearly 31 lakh saplings of various native species on its three sides to rid Delhi of the malady of frequent dust storms from its western neighbour.
The natural barrier is to come up all along Delhi border with Haryana, Rajasthan and Uttar Pradesh, while also encompassing the Aravali and the Yamuna forests areas.
The official listed said the scheme has two objectives – absorption of pollution-causing particulate matters by trees and shielding Delhi from the choking dust storms, coming in from Rajasthan every year due to western disturbances.
He said based on scientific studies, sufficiently tall and dense trees like those of "pilkhan, goolar, mango, mahua" and other native tress have been chosen for this scheme. These tress prevent the dust particle from rising above in the sky due to low atmospheric pressure and stop them from condensing at few meters above the ground, he said.
Also included in this scheme are the tress of "pepul, neem, banyan, berry, amla (Indian gooseberry), jamun, amltash, harre, bahera" and other tress which release ore Oxygen. Of all these trees, pepul, which releases Oxygen round the clock, would be the highest chunk of trees to be planted in the scheme.
The official said dust particles and other pollutants of the air easily get deposited on the leaves of ever green trees and washed down.
