Q2. Which one of the following is not a cause of Desertification in Rajasthan?

1) Overgrazing
2) Deforestation
3) Urbanization
4) Improper soil and water Management

Ans. 4) Improper soil and water Management

Explanation: 

Four human activities represent the most immediate causes Desertification: over-cultivation exhausts the soil, overgrazing removes the vegetation cover that protects it from erosion, deforestation destroys the trees that bind the soil to the land and poorly drained irrigation systems turn croplands salty. 

Overgrazing - Overgrazing is the destruction of vegetation by cattle, results in barren exposed soil; if erosion continues, it contributes to desertification.

Deforestation - Destruction of vegetation in arid regions destroys the trees that bind the soil that leads to desertification.

Urbanisation - Urban expansion, including the establishment of industrial and tourist facilities and the construction of road networks and airports causes loss of productive land. 
Continued encroachment into agricultural lands due to rapid changes in the demographic structure will further reduce productive agricultural areas and will create added pressure to exploit marginal lands, which will lead to accelerated desertification of the area.

Improper soil and water ManagementIncorrect irrigation is commonly used in poorer areas. Farmers are using canal irrigation and other poor techniques because of the lack of water. This type of irrigation causes a build up of salt in the soil. (Desertification, 2005)
