The most critical cause of desertification in Nigeria is?
Answer Details
The most critical cause of desertification in Nigeria is excessive pressure of land use. This occurs when there is an overuse or exploitation of the land, leading to a reduction in vegetation cover, erosion, and ultimately, desertification. Examples of activities that contribute to excessive pressure of land use include overgrazing, deforestation, and improper agricultural practices such as continuous cultivation without adequate soil conservation measures. As a result, the land becomes less productive, and the ecosystem becomes vulnerable to desertification.
