Desertification is a man-made or natural process of degrading arable land into that which has such poor soil that farming is not possible or is nearly impossible. Human causes include over-farming, leveling forests for farm land or urban development, and the use of river dams. Natural causes include climate change toward less yearly rainfall, and erosion caused by water, wind or gravity. Desertification Climate Change Environment Science.
Desertification is a type of land degradation in which a relatively dry land region becomes increasingly arid, typically losing its bodies of water as well as vegetation and wildlife. (wikipedia)
- Wikipedia: 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. It is caused by a variety of factors, such as through climate change and through the overexploitation of soil through human activity. 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, which traces its cause back to human overexploitation. Desertification is a significant global ecological and environmental problem.
