NEET BIOLOGY

Detailed explanation-1: -Excessive loss of trees due to deforestation resulted in dried climate and desertification (or the transformation of the fertile land into desert). For fuel-Till now the greatest use of forest products worldwide is for fuel.

Detailed explanation-2: -Human activities that contribute to desertification include the expansion and intensive use of agricultural lands, poor irrigation practices, deforestation, and overgrazing. These unsustainable land uses place enormous pressure on the land by altering its soil chemistry and hydrology.

Detailed explanation-3: -As the upper fertile layer of soil is removed by erosion, the soil quality decreases day by day. And eventually converts it to a desert as the soil is no more suitable for plants. Was this answer helpful?

Detailed explanation-4: -Desertification and deforestation involve a drastic change in microclimates. For instance, if shrubs and trees are felled, the noonday sun will fall directly on hitherto shaded soil; the soil will become warmer and drier, and organisms living on or in the soil will move away to avoid the new harshness.

Detailed explanation-5: -Hint: Deforestation term refers to the cutting down of trees from the area that we generally called as forest, it can be due to many reasons whereas desertification is the process in which the land and the soil is left devoid of humus that makes it infertile and eventually it gets converted into desert.
