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, which is located in the Sahel region of West Africa, [5] has an arid and semi-arid climate, which makes it especially vulnerable to desertification and the negative consequences of climate change. [6] These environmental problems are further made worse by population pressure.
Ninety percent of Africa's population requires wood to use as fuel for heating and cooking. As a result, forested areas are decreasing daily, as for example, in the region of equatorial evergreen forests. According to the United Nations Environment Programme, Africa's desertification rate is twice that of the world's. [4] Deforestation of ...
Drought is a phenomenon that occurs in Nigeria and impacts the whole nation. The arid and semiarid regions are more sensitive than the dryer south, but the degree of vulnerability varies. In Northern Nigeria , there are several records of drought occurrences that resulted in famines in the years 1914, 1924, 1935, 1943, 1951–1954, 1972–1973 ...
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.
Geographic areas most affected are located in Africa (Sahel region), Asia (Gobi Desert and Mongolia) and parts of South America. Drylands occupy approximately 40–41% of Earth's land area and are home to more than 2 billion people. [7] Effects of desertification include sand and dust storms, food insecurity, and poverty.
Deforestation leads to desertification, ecosystem and biodiversity loss, land degradation, increased greenhouse gases, and soil erosion, significantly impacting the environment and human well-being [26] Deforestation threatens the sustainability of the environment, which in turn may lead to risks for citizens' quality of life due to economic ...
The main sources of Africa's 3.6% share of the world's Carbon dioxide emissions are gas flaring in the Niger Delta and coal-fired power plants in South Africa. [23] But, the continent's forests are rapidly disappearing because of desertification and deforestation, which has negative consequences for both Africa and the climate at large. [24]
