The Great Indian Desert, often known as the Thar Desert, is a huge and dry area in the Indian subcontinent's northwest. The Great Indian desert is to the northwest of the Aravali highlands. It is a place with undulating terrain with longitudinal dunes and barchans. Thar derives its name from thul, the common word for the region's sand ridges. It is split between Rajasthan state in northern India and Punjab and Sindh provinces in eastern Pakistan. This article will explain to you about The Thar Desert which will be helpful in Geography preparation for the UPSC Civil service exam.

The Thar Desert

• The Thar Desert is a vast dry area covering over 200,000 square kilometers. It serves as a natural barrier between India and Pakistan.
• The surface is made up of aeolian (wind-deposited) sand that has accumulated over 1.8 million years.
• The landscape of the desert is undulating, with high and low sand dunes divided by sandy plains and low barren hills, or bhakars, that rise suddenly from the surrounding plains.
• The dunes are constantly moving and changing shape and size.
• Barchan, often written Barkhan, is a crescent-shaped sand dune formed by the action of wind from a single direction. It is one of the most prevalent forms of dunes and may be found in sandy deserts all over the world.
• It is bounded on the west by the irrigated Indus River plain, on the north and northeast by the Punjab Plain, on the southeast by the Aravalli Range, and on the south by the Rann of Kachchh.
• At such latitude, the subtropical desert climate is caused by sustained high pressure and subsidence.
• The summer monsoon winds that bring rain to most of the subcontinent prefer to skip the Thar to the east.

The Thar Desert - Formation

• The amount of rain falls from east to west. The western region of Rajasthan receives little to no rainfall. This is because of the following factors.
• The Arabian Sea branch of the southwest monsoon blows through Gujarat's Kathiawar area and escapes to the north-west.
• There are no towering mountains to keep these winds at bay. The Aravalli range in Rajasthan runs parallel to the path of the monsoon winds and cannot prevent them from moving north.
• The region's high temperatures improve the water retention capacity of the winds and diminish the likelihood of rainfall.
• All of these factors contribute to high rainfall shortage, resulting in the creation of the Thar desert.

The Thar Desert - Features

• The Great Indian Desert extends from the Aravali Hills in the northeast to Punjab and Haryana in the north, the Rann of Kutch along the western coast, and the Indus River alluvial plains in the northwest.
• The soil of the Great Indian Desert remains dry all year and is prone to wind erosion.
• High-speed winds blast solid sand from the desert, depositing some of it on productive fields. The desert's sand dunes shift as a result of the strong winds.
• Due to the fact that very few local tree species can tolerate the severe desert climate, non-native tree species are planted.
• Jojoba has shown to be the most promising of these, as well as the most economically feasible for planting in these places.
• It has a dry climate with little vegetation. Because of these distinguishing characteristics, this is also known as Marusthali.
• This area was thought to be under water during the Mesozoic era. This is supported by data from the Akal Wood Fossil Park and sea deposits.
• The Luni River is the only large river in this area.
• It is a water-stressed region due to little precipitation and excessive evaporation. Some streams cease after a certain distance and represent a typical occurrence of inland drainage by joining a lake or playa.
• The lakes and playas have brackish water, which is the primary source of salt

The Thar Desert - Inhabitation

• The Thar Desert has the highest population density of any desert on the planet.
• Hindus, Jains, Sikhs, and Muslims are among the people who live in India.
• The Thar Desert is home to over 40% of Rajasthan's entire population. Agriculture and livestock husbandry are the primary vocations of the residents.
• This desert is dominated by a vibrant culture steeped in tradition.
• Folk music and poetry are quite popular among the locals.
• The Thar is one of the world's most densely inhabited desert environments, with agriculture and animal husbandry being the primary professions of its population.
• The majority of agricultural production comes from kharif crops, which are cultivated in the summer and sown in June and July.
• These include bajra, pulses such as guar, jowar (Sorghum vulgare), maize (zea mays), sesame, and groundnuts, which are harvested in September and October.

Conclusion

The Thar Desert, also known as the Great Indian Desert, is a huge desert area in the Indian subcontinent's northern corner. The Thar is one of the world's most densely inhabited desert environments, with agriculture and animal husbandry being the primary professions of its population. The Thar Desert offers recreational value in the form of desert festivals held each year. Rajasthan desert festivities are celebrated with fervour and vigour. This festival takes place once a year in the winter.
