Question

Read and select the incorrect option about desertification.
a. A desert is created when barren patches of land meet
b. Desertification is the result of increased urbanisation
c. Deserts are arid patches of land
d. Slash and burn method is the one of the major cause of desertification

Answer 1

Hint: A type of land degradation in drylands in which the productivity is lost biologically is called a desert. It can turn out to be like that as a result of the natural processes or brought by activities of human beings due to which the fertile areas become increasingly arid. Such areas can be spread due to various reasons.

Complete answer:
- The arid patches of land can be termed as the Deserts. However, the definition of the term desertification cannot be obtained wholly from this sentence.
- We can state that factors like climate change (particularly the current global warming and overexploitation of soil as a result of human activity can result in the spreading of the deserts. The deserts occur with a far-reaching socio-economic and political significance.
- One can say that the result of increased urbanization will be the desertification. In general, it can also be caused by the subsequent meeting of barren patches of land.
- In addition to these, some of the inappropriate practices in the agricultural field such as the Slash and burn method can also be the root causes of the formation of the desert.

Hence, the correct answer is option (C).

Note: The elders say that the development of deserts has occurred naturally throughout geological history. The desert forms because of unchecked depletion of nutrients in the soil that are essential for the soil. However, on the other hand, the virtual "soil death" can be spoken of, whose traces cause it back to human overexploitation. Desertification is a significant global ecological and environmental problem when the deserts emerge due to remain arable.
