Influence of the Himalayas on Indian Agriculture: 

1. Fertile soil: The sediments carried by the Himalayan rivers are deposited in the northern plain in the form of fertile soil. It makes the plain one of the most fertile lands in the world, e.g.: Bhabar, Terai, Bhangar. 

2. Source of rivers : 

• The Himalayas act as a huge reservoir of water for the north Indian rivers.
• All these perennial rivers are the lifeline of north India and are suitable for the construction of multipurpose projects which strengthens Indian agriculture.
