The main occupations of people living in the desert are agriculture and animal husbandry. Agriculture is not a dependable proposition in this area—after the rainy season, at least 33% of crops fail. Animal husbandry, trees and grasses, intercropped with vegetables or fruit trees, is the most viable model for arid, drought-prone regions. The region faces frequent droughts. Overgrazing due to high animal populations, wind and water erosion, mining and other industries result in serious land degradation.
Bajra is the main kharif crop in Thar

The agricultural production is mainly from the Kharif crops. The Kharif crops are the crops that are grown in the summer season and are seeded in the months of June and July. These crops are harvested in the months of September and October and include Bajra (Pennisetum typhoideum), Pulses, Jowar (Sorghum vulgare), Maize (Zea mays), Sesame and Groundnuts. In past few decades the development of canals, tube wells etc. has changed crop pattern. Now the desert districts in Rajasthan have started producing rabi crops like wheat, mustard, cumin seed etc. cash crops also.
