In the las few years most of the north-African oases have been subject to profound economic and social changes. Nevertheless traditional elements persist until to-day as can be shown by examples of the Draa-oasis. The social development actually is caracterized by a significant rural exodus to the cities of northern Morocco. The nomads of the Hammada, on the other hand, show an increasing tendency to sedentarize. With the application of new agricultural techniques and irrigation systems, both possible since the construction of the Hassan ad Dakhil Dam near Ouarzazate in 1972, a total abandonment of traditional agriculture and nomadisme can be expected for the near future.
