The Aravalli mountain range that spans four states — Gujarat, Rajasthan, Haryana and Delhi — was never continuous, but mining and construction activities have made it even more broken. These two hills in Tijara village of Rajasthan were a monolith just a decade ago, but stone mining has destroyed them.

The gaps were recorded by satellite pictures and verified on the ground. Photo: Vikas Choudhary; Text: Pranay LalDegradation of Aravallis is also evident in the loss of forest cover. During 1972-75, the Aravalli districts in Rajasthan recorded 10,462 sq km of area under various categories of forest. By 1981-84, the forest cover reduced to 6,116 sq km, says a 2018 report by Delhi-based Rajiv Gandhi Institute for Contemporary Studies.

Of the state’s 22 districts, Aravallis are present in Mewat, Faridabad, Gurugram, Mahendragarh and Rewari, all of which are currently, or were till recently, heavily mined and have undergone rapid developmental and construction activities.
