Agriculture

Farming on the Indus-Ganga Plain primarily consists of rice and wheat grown in crop rotation. Other crops include maize, millets, barley, sugarcane, and cotton. The main source of rainfall is the southwest monsoon which is normally sufficient for general agriculture. The many rivers flowing out of the Himalayas provide water for major irrigation works. Due to a rapidly growing population (as well as other factors), this area is considered at high risk for water shortages in the future. The area constitutes the land between the Brahmaputra River and the Aravalli Range. The Ganga and other rivers such as the Yamuna, the Ghaghara and the Chambal River flow through the area.
