34.Mauritania

Mauritania, officially the Islamic Republic of Mauritania, is a country in the Maghreb region of western North Africa. It is the eleventh largest country in Africa, and is bordered by the Atlantic Ocean to the west, by Moroccan-controlled Western Sahara in the north, by Algeria in the northeast, by Mali in the east and southeast, and by Senegal in the southwest. The country derives its name from the ancient Berber Kingdom of Mauretania, which existed from the 3rd century BC to the 7th century AD, in the far north of modern-day Morocco. Approximately 90% of Mauritania's land is within the Sahara Desert and consequently the population is concentrated in the south.
