The Thar Desert, also known as the Great Indian Desert, is a large arid region in the northwestern part of the Indian subcontinent that covers an area of 200,000 km2 (77,000 sq mi) and forms a natural boundary between India and Pakistan. It is the world's 17th largest desert, and the world's 9th largest subtropical desert. About 85% of the Thar Desert is located within India, with the remaining 15% in Pakistan. In India, it covers about 170,000 km2 (66,000 sq mi), and the remaining 30,000 km2 (12,000 sq mi) of the desert is within Pakistan. The Thar desert forms approximately 5%(~4.56%) of the total geographic area of India. More than 60% of the desert lies in the state of Rajasthan, and extends into Sindh, Gujarat, Punjab, and Haryana. The desert comprises a very dry part, the Marusthali region in the west, and a semidesert region in the east with fewer sand dunes and slightly more precipitation.
The Thar Desert extends between the Aravalli Hills in the north-east, the Great Rann of Kutch along the coast and the alluvial plains of the Indus River in the west and north-west. Most of the desert is covered by huge shifting sand dunes that receive sediments from the alluvial plains and the coast. The sand is highly mobile due to strong winds occurring before the onset of the monsoon. The Luni River is the only river integrated into the desert. Rainfall is limited to 100–500 mm (3.9–19.7 in) per year, mostly falling from July to September. Salt water lakes within the Thar Desert include the Sambhar, Kuchaman, Didwana, Pachpadra and Phalodi in Rajasthan and Kharaghoda in Gujarat. These lakes receive and collect rain water during monsoon and evaporate during the fat season. The salt is derived by the weathering of rocks in the region. Lithic tools belonging to the prehistoric Aterian culture of the Maghreb have been discovered in Middle Paleolithic deposits in the Thar Desert.
The soil of the Thar Desert remains dry for much of the year and is prone to wind erosion. High velocity winds blow soil from the desert, depositing some on neighboring fertile lands, and causing shifting sand dunes within the desert. Sand dunes are stabilised by erecting micro-windbreak barriers with scrub material and subsequent afforestation of the treated dunes with seedlings of shrubs such as phog, senna, castor oil plant and trees such as gum acacia, Prosopis juliflora and lebbek tree. The 649 km (403 mi) long Indira Gandhi Canal brings fresh water to the Thar Desert. It was conceived to halt spreading of the desert to fertile areas. There are few local tree species suitable for planting in the desert, which are slow growing. Therefore, exotic tree species were introduced for plantation. Many species of Eucalyptus, Acacia, Cassia and other genera from Israel, Australia, US, Russia, Zimbabwe, Chile, Peru and Sudan have been tried in Thar Desert. Acacia tortilis has proved to be the most promising species for desert afforestation and the jojoba is another promising species of economic value found suitable for planting in these areas.
The Thar Desert is the most widely populated desert in the world, with a population density of 83 people per km2.[8] In India, the inhabitants comprise Hindus, Muslims, and Sikhs. In Pakistan, inhabitants also include both Muslims and Hindus. About 40% of the total population of Rajasthan live in the Thar Desert. The main occupation of the people is agriculture and animal husbandry. A colourful culture rich in tradition prevails in this desert. The people have a great passion for folk music and folk poetry. Jodhpur, the largest city in the region, lies in the scrub forest zone. Bikaner and Jaisalmer are located in the desert proper. A large irrigation and power project has reclaimed areas of the northern and western desert for agriculture. The small population is mostly pastoral, and hide and wool industries are prominent. The desert's part in Pakistan also has a rich multifaceted culture, heritage, traditions, folk tales, dances and music due to its inhabitants who belong to different religions, sects and castes. In the years 1965 and 1971, population exchanges took place in the Thar between India and Pakistan. 3,500 Muslim families shifted from the Indian section of the Thar to Pakistani Thar whilst thousands of Hindus also migrated from Pakistani Thar to the Indian section of the Thar.
The Thar is one of the most heavily populated desert areas in the world with the main occupations of its inhabitants being agriculture and animal husbandry. Agriculture is not a dependable proposition in this area because after the rainy season, at least one third 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 have resulted in serious land degradation. Mustard fields in a village of Shri Ganganagar district (Rajasthan, India). Agricultural production is mainly from kharif crops, which are grown in the summer season and seeded in June and July. These are then harvested in September and October and include bajra, pulses such as guar, jowar (Sorghum vulgare), maize (zea mays), sesame and groundnuts. Over the past few decades the development of irrigation features including canals and tube wells have changed the crop pattern with desert districts in Rajasthan now producing rabi crops including wheat, mustard and cumin seed along with cash crops. The Thar region of Rajasthan is a major opium production and consumption area. The Indira Gandhi Canal irrigates northwestern Rajasthan while the Government of India has started a centrally sponsored Desert Development Program based on watershed management with the objective of preventing the spread of desert and improving the living conditions of people in the desert.
The Thar Desert provides recreational value in terms of desert festivals organized every year. Rajasthan desert festivals are celebrated with great zest and zeal. This festival is held once a year during winters. Dressed in brilliantly hued costumes, the people of the desert dance and sing haunting ballads of valor, romance and tragedy. The fair has snake charmers, puppeteers, acrobats and folk performers. Camels, of course, play a starring role in this festival, where the rich and colorful folk culture of Rajasthan can be seen. Camels are an integral part of the desert life and the camel events during the Desert Festival confirm this fact. Special efforts go into dressing the animal for entering the competition of the best-dressed camel. Other interesting competitions on the fringes are the moustache and turban tying competitions, which not only demonstrate tradition but also inspire its preservation. Both the turban and the moustache have been centuries old symbols of honor in Rajasthan. Evenings are meant for the main shows of music and dance. Continuing till late into the night, the number of spectators swells up each night and the grand finale, on the night of a full moon, takes place by sand dunes.
