Desertification causes the Sahara region to become more arid, with less water and arable land. Constructing aqueducts into the Sahara is not practical due to its vast and dry nature. Desert regions lack resources to support large cities. Desertification makes agriculture harder, not easier. So, people would migrate away from the desert to find better living conditions.
