DESERTIFICATION

DESERTIFICATION

A major impact of desertification is reduced and diminished, for example, by transition from land dominated by to non-native^]. For example, in the semi-arid regions of southern California, many and ecosystems have been replaced by non-native, invasive grasses due to the shortening of fire return intervals. This can create a monoculture of that cannot support the wide range of animals once found in the original ecosystem^]. In s central highland 10% of the entire country has desertified due to agriculture by indigenous peoples^[

Desertification is the degradation of land in arid and dry areas due to various factors: including variations and human activities.

Desertification is induced by several factors, primarily anthropogenic causes, which began in the ra and continue at the highest pace today. The primary reasons for desertification are er-cultivation, increased fire frequency, of increased and global

n these marginal areas activity centres may stress the beyond its tolerance limit, resulting in degradation of the land. By pounding the soil with their hooves, ompact the substrate, increase the proportion of fine material, and reduce the rate of the soil, thus encouraging by wind and water. Grazing and collection of firewood reduce or eliminate plants that bind the soil and prevent All these come about due to the trend towards settling in one area instead of a nomadic culture
