To check the expansion of Thar desert Afforestation methods is expected to yield the best results. It reduces the pollution level. It minimizes the effect of drought and Global Warming. It helps the factories to have a proper use of plant items without leaving a bad effect in the society and environment. It minimizes the effect of soil erosion.

B. Camels

The Raika are a subgroup of the Rebari, the largest pastoral group of Western India that is concentrated in Rajasthan and Gujarat and estimated to number about 500,000-800,000 people .  The Raika consist of two groups that do not intermarry, the Maru and Godwar Raika. The Maru Raika are most densely distributed around Jodhpur and in Pali district of Rajasthan, whereas the Godwar Raika can be found in southern Pali district and in Sirohi district. According to their myth of origin, the first Raika was specifically created by Lord Shiva (an Indian God) to take care of the one-humped camel.

Although Raika identity remains closely associated with the camel, they have diversified into sheep, goat, cattle, and even buffalo keeping. This caste provides an important service to farmers and rural poor by providing drought animals (camels and bullocks), as well as cows with good milk yields. As large-scale producers of sheep, many of which are exported to the Middle East, they also generate substantial amounts of foreign currency for India.

B. Lack of vegetation

The main cause of soil erosion is the removal of vegetation. Vegetation removal takes place due to removal of forest covers and exposes the topsoil to water and wind. Unscientific farming has also led to barren lands.

The crystalline granites produce laterite type of soils in moist parts. Laterite is a rock type soil rich in iron and aluminium, and is commonly considered to have formed in hot and wet tropical areas. Nearly all laterites are of rusty-red coloration, because of high iron oxide content. 

The largest area in Rajasthan is occupied by desert soil, which covers the area west of the Aravallis up to the Pakistan border. The entire area is ill watered and unproductive and characterized with sand dunes, hillocks and rock outcrops. The soils contain about 90 to 95 per cent sand and about 5 to 7 per cent clay. Among the given options both the statements are true which says that the percentage of calcium carbonate is high and has very low organic content.

Alluvial soil which occupies Alwar, Bharatpur, Jaipur and Sawai Madhopur and the central part of Ganganagar district is deficient in Lime, Phosphoric acid, Humus. It varies from clayey to sandy loam in texture. The top soil contains 'kankar’ which lie either on sands or sandy clays. A wide variety of crops including wheat, rice, cotton and tobacco are grown in this soil.

Formation of soil is called pedogenesis. Soil formation is the process of soil formation from its parental material. In addition to the soil parent material, soil formation is also dependent upon other prevailing processes like climate, relief, etc.

Dark lava soils are also called as black soils or black cotton soils. These are present in the Bhilwara district and the major parts of Udaipur district, Chittaurgarh district, Sirohi district and the tract of Aravali Hills forms a part of inter-mountain plateau an consists of dark- lava soils. Major cash crops like cotton and sugarcane are grown in this black soil region. 

The Hadauti plateau is fertile with black soil due to the presence of Chambal River and its tributaries Kalisindh, Parvati and Chakan. The soil is alluvial. The Hadoti region consists of the districts of Bundi, Baran, Jhalawar and Kota.

In natural depressions like Pachpadra, Sambhar, Ranns of Jalore of Rajasthan saline sodic salts are found. color of these soils are dark grey to pale brown. Water table is sometime close to surface. Cultivation is not possible due to the impeded drainage and high degree of salinity. The only vegetation consists of some salt tolerant grasses and shrubs
