Compared to many countries that are located in a similar latitudinal belt, such as in northern Arabia, Rajasthan has a less harsh climate. The State's scorching and dry summers and its parched landscape is undergoing significant changes because of the developmental effort that have led to the spread of the Indira Gandhi Nahar.
