The border area of Mauritania and Senegal in westernmost Africa is an example of both expanding irrigation and desertification. The international border between Mauritania and Senegal is the Senegal River, flowing westward and interrupting the arid lands to the north and south. The regional capital of southwestern Mauritania is Rosso, which is on the north bank of the river, and the town of Richard Toll ("Richard's Field" in the Wolof language) is on the south bank. The effects of a highway, which connects the regional capital Rosso to the national capital Nouakchott, on the desert is seen in the close-up images.
