The state in Nigeria that is most susceptible to desert encroachment is Katsina. Katsina is located in the northern region of Nigeria and falls within the Sahelian zone which is characterized by a semi-arid climate with low and erratic rainfall. This region is particularly vulnerable to desertification, which is the process of fertile land becoming desert due to a combination of natural and human factors such as deforestation, overgrazing, and climate change. The dry and dusty conditions in Katsina make it more prone to desertification and as such, the state is considered one of the most affected by desert encroachment in Nigeria.
