Desertification
Desertification is a type of land degradation in which a relatively dry area of land becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife . [2] It is caused by a variety of factors, such as through climate change (particularly the current global warming ) [3] and through the overexploitation of soil through human activity. [4] When deserts appear automatically over the natural course of a planet's life cycle, then it can be called a natural phenomenon; however, when deserts emerge due to the rampant and unchecked depletion of nutrients in soil that are essential for it to remain arable, then a virtual "soil death" can be spoken of, [5] which traces its cause back to human overexploitation. Desertification is a significant global ecological and environmental problem . [6]

Desertification is the extreme deterioration of land in arid and dry sub-humid areas due to loss of vegetation and soil moisture; desertification results chiefly from man-made activities and influenced by climatic variations. It is principally caused by overgrazing , overdrafting of groundwater and diversion of water from rivers for human consumption and industrial use, all of these processes fundamentally driven by overpopulation . |

Desertification is the degradation of land in arid and dry sub-humid areas, resulting primarily from human activities and influenced by climatic variations. It's also a failure of the ecological succession process. A major impact of desertification is biodiversity loss and loss of productive capacity , for example, by transition from land dominated by shrublands to non-native grasslands. In the semi-arid regions of southern California, many coastal sage scrub and chaparral ecosystems have been replaced by non-native, invasive grasses due to the shortening of fire return intervals. This can create a monoculture of annual grass that can not support the wide range of animals once found in the original ecosystem. In Madagascar 's central highland plateau, 10% of the entire country has been lost to desertification due to slash and burn agriculture by indigenous peoples. In Africa , if current trends of soil degradation continue, the continent might be able to feed just 25% of its population by 2025, according to UNU 's Ghana-based Institute for Natural Resources in Africa. [1] Globally, desertification claims a Nebraska-sized area of productive capacity each year. [2] |

Desertification is the degradation of land in arid , semi arid and dry sub-humid areas resulting from various climatic variations, but primarily from human activities. Current desertification is taking place much faster worldwide than historically and usually arises from the demands of increased populations that settle on the land in order to grow crops and graze animals. |
