Abstract:
Land degradation is a process in which the value of the biophysical environment is
affected by a combination of human-induced processes acting upon the land. It is
viewed as any change or disturbance to the land perceived to be deleterious or
undesirable. Land degradation: a decline in the quality or performance of land. Or
erosion of the earth ‘s land surface by water, wind, or ice. Land degradation affects
people and ecosystems throughout the planet and is both affected by climate change
and contributes to it. The prolonged effect of land degradation has re sulted in erratic
rainfall causing severe droughts at ir-regular intervals, and these droughts threaten the
livesand livelihoods of millions of people. According to the FAO, the world's cultivated
soils - meaning soils that have been rearranged - have lost between 25 and 75 percent
of their original carbon stock, which has been released into the atmosphere in the form
of carbon dioxide. The simulated results of costs of loss of milk, meat, and costs
associated with weight loss of animals not slaughtered or sold associated with land
degradation in grazing biomass.
