Under the Aravalli Green Wall initiative, the Center intends to repair the damaged land in the 700-kilometer span between Gujarat and Delhi by creating a green cover along the Aravalli mountain range.

About the Aravalli Range

Located in North-Western India, the Aravalli Range is a mountain range that stretches roughly 670 km (420 mi) southwest from Delhi, through southern Haryana, Rajasthan, and ends in Ahmedabad, Gujarat.
Guru Shikhar on Mount Abu, at 1,722 meters (5,650 feet), is the highest summit.
Originating in the Proterozoic age, the Aravalli Range is possibly the oldest geological feature on Earth.

Formation of Aravallis

Because of tectonic activity in the Indian subcontinent, the Aravalli Range was created during the Proterozoic Eon through a process known as orogeny, or mountain-building.
The range is made up of ridges and hills that were created by a mix of sedimentary and volcanic rock types.
Metamorphic rock makes up the majority of the range; the most prevalent rock types in the area are schist, granite, and gneiss.
Over millions of years, the Aravalli Range has seen substantial erosion, and the forces of water and weathering have sculpted its current topography.

Aravalli Green Wall Initiative

The project is a significant effort to green the five-kilometer buffer zone surrounding Aravalli Hill.
In order to fight desertification and soil degradation, the Union Environment Ministry wants to establish green corridors throughout the nation.
The project encompasses the Aravalli Hills region, which comprises more than 6 million hectares of land in the states of Haryana, Rajasthan, Gujarat, and Delhi.
Along with revitalizing and repairing surface water bodies, including ponds, lakes, and streams, the project will entail planting native tree and shrub species on scrubland, wasteland, and degraded forest land.
To improve local populations' quality of life, the initiative will also concentrate on pasture development and agroforestry.
