s and seasonal rivers terminate in the deserts to the south and plateaux to the east of the mountains. The High-Atlas Mountains are inhabited by Berbers, who live from agriculture and pastoralism in the valleys. In the steppe zone of the High-Atlas, where precipitations are low, the locals created a smart technique in managing the low precipitations and the weak soil. They turn the rather semi-arid lands into fertile valleys called locally by Agdal (garden in Berber). This technique has intrigued many Western agriculturalists, in which they were impressed by the high efficiency of this agricultural system. Many scientists, particularly French scientists, make yearly expeditions to observe the community and their living system.

The annual rainfall is between . The drought in the summer months, interrupted by thunderstorms, is usually intense. Snow falls between November and April, but can persist from September to June in the peaks. Important rivers flow through the valleys (including Asif Melloul, Oued n'Fis, and Oued Tessaout) supply the fertile basins like Aït Bou Guemez and Imilchil. These conditions allow the existence of pine, oak and cedar forests.
