The Thar Desert: the Great Indian Desert
India serves as home to many desert fauna, each showcasing distinct ecological communities. The largest Thar desert in India extends from the state of Rajasthan in northwest India to Punjab and Sindh province in Pakistan. The western, southern, and northwestern parts of the subcontinent are the major arid regions of India.
Geography of Thar
Also recognized as the Great Indian Desert, this dry area spans approximately 92,200 square miles and comes on 7th no. on the list of the world’s largest deserts. The name Thar originated t’hul, a phrase for sand ridges characteristic of this desert. About 10 of the Thar Desert consists of dunes, whereas the remaining comprises crisp rocks, beds of dry salt lake, and pastures. The Indus River creates a border in the west of the desert. Thar is an arid semitropical region because of the monsoon that carries rainfall to the area in the rest of India. The site has extreme temperatures that rise from freezing in winter to 122 degrees Fahrenheit in summer.
The Thar Desert spread to the northeast between the Aravalli hills. It also extends to states like Kutch and Punjab. Vast shifting dunes are spread over most of the desert, receiving sediment from the alluvial plain.
The Luni River is integrated as the only river in the desert. Rainwater is limited to 4 to 20 inches per year. Most of the rain occurs from July to September. Kuchaman, Sambhar, and Didwana saltwater lakes are situated in the Thar Desert. Phalodi and Pachpadra are saltwater lakes in Rajasthan.
The maximum water in these lakes comes from rainfall. This water evaporates during the dry time of the year. Salt is obtained by the process of weathering rocks in the area. The soil of Rajasthan remains dry for most of the time. Fast-moving winds blow the desert soil. These winds deposit some soil on fertile neighbouring land and drain some sand dunes of the desert. The “Indira Gandhi Canal” is the source of fresh water in the desert. The length of the Indira Gandhi Canal is 649 km. The Indira Gandhi Canal is built to prevent the desert from spreading to productive zones.
There are some homegrown tree species in the desert. This species is rising at a slow rate. Acacia species have shown to be beneficial for afforestation in desert areas, and Jojoba is also a promising plant species.
