Dimapur district administration in Nagaland has banned extraction of sand gravels and boulders from rivers and streams of the district.
Special focus has been given on 200 meters upstream and downstream from the existing bridges and culverts.
In a notification, Dimapur deputy commissioner Rajesh Soundararanjan said the order was issued to preserve the rivers and its resources.
He added that the ban will also address the issue of inundation of floodwater in the surrounding villages and colonies along the river bank and avoid damage to public assets like bridges.
