As part of its national Land Degradation Neutrality targets, South Africa aims to restore 633 702 hectares of land affected by woody encroachment. [228] Land users in South Africa commonly combat woody encroachment through clear felling, burning, intensive browsing or chemical control in the form of herbicide application. [220]
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 .
Ghana's drylands in the northern Sudanese and Guinea savannah regions are especially at risk from erosion; in these areas, land deterioration is known as "desertification." The risk of desertification is present on about 35% of Ghana's land. An estimated $1.4 billion, or 6% of Ghana's GDP, is lost to land degradation each year in the country. [3]
The United Nations Convention to Combat Desertification in Those Countries Experiencing Serious Drought and/or Desertification, Particularly in Africa (UNCCD) is a Convention to combat desertification and mitigate the effects of drought through national action programs that incorporate long-term strategies supported by international cooperation and partnership arrangements.
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."
Overgrazing by livestock can lead to land degradation. Land degradation is a process where land becomes less healthy and productive due to a combination of human activities or natural conditions. The causes for land degradation are numerous and complex. [1] Human activities are often the main cause, such as unsustainable land management practices.
The large scale felling of trees and the resulting decreases in forest areas are the main environmental issues of the African Continent. Rampant clearing of forests and land conversion goes on for agriculture, settlement and fuel needs. [3] Ninety percent of Africa's population requires wood to use as fuel for heating and cooking.
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.
