Dust storms can contribute to certain respiratory disorders such as pneumonia, skin irritations, asthma and many more. [26] They can pollute open water, reduce the effectiveness of clean energy efforts, and halt most forms of transportation. Dust and sand storms can have a negative effect on the climate which can make desertification worse.
It can also be caused by immobile, travel restricted populations of native or non-native wild animals. Overgrazing reduces the usefulness, productivity and biodiversity of the land and is one cause of desertification and erosion. Overgrazing is also seen as a cause of the spread of invasive species of non-native plants and of weeds.
Desertification reduces crop yields, causes food shortages, and increases poverty in impacted populations by destroying fertile land and water supplies. People displaced as a result of desertification can lead to increased competition for scarce resources and conflicts, worsening economic issues. [39]
The cultivation of semi-arid regions encourages erosion of soil and is one of the causes of increased desertification. Desert farming is possible with the aid of irrigation, and the Imperial Valley in California provides an example of how previously barren land can be made productive by the import of water from an outside source.
More than 75 percent of the globe became permanently drier over the past three decades, according to a report from the United Nations Convention to Combat Desertification (UNCCD). The report ...
Much of the soil has rocks or clay from volcanic activity. Other causes include erosion, desertification, and deforestation. Another source of soil degradation is the improper management of waste, lack of facilities and techniques to handle waste lead to the dumping of waste in soil, therefore causes soil degradation by process such as leaching.
