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.
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]
