Desertification is a gradual process of increased soil aridity.Desertification has been defined in the text of the United Nations Convention to Combat Desertification (UNCCD) as "land degradation in arid, semi-arid and dry sub-humid regions resulting from various factors, including climatic variations and human activities."
Desertification in Africa is a form of land degradation that involves the conversion of productive land into desert or arid areas. This issue is a pressing environmental concern that poses a significant threat to the livelihoods of millions of people in Africa who depend on the land for subsistence.
But included in that 10–20% of land is the approximately 9 million square kilometers of seasonally dry-lands that humans have converted to deserts through the process of desertification. [7] The tallgrass prairies of North America, on the other hand, have less than 3% of natural habitat remaining that has not been converted to farmland.
Desertification is one of the issues of environmental concern in Nigeria, particularly the northern part of the country. According to UNEP [4] in 1993, Northern Nigeria has one of the highest rates of deforestation in the world at about 3.5%, caused by land degradation, increase in agricultural intensity, over-grazing of livestock, and demand for fuel by cutting down trees.
Humans play a role in desertification through ill-advised land utilization practices and the mounting pressure placed on finite resources due to population growth. Essentially, human-induced desertification is a result of the exploitation of "non-ideal lands," excessive resource exploitation, unsustainable practices, and the failure to replace ...
Human-induced land degradation and water scarcity are increasing the levels of risk for agricultural production and ecosystem services. [ 1 ] The United Nations estimate that about 30% of land is degraded worldwide, and about 3.2 billion people reside in these degrading areas, giving a high rate of environmental pollution. [ 2 ]
Five people have died in the rough waters of the Atlantic Ocean off Palm Beach County’s coast since Nov. 1. The two most recent: A 15-year-old boy and a 55-year-old man, one in Boynton Beach and ...
