Dry farming is generally possible and commercially profitable in the eastern zone, where fine forests and abundant vegetation also exist. In the western zone cereal crops can be cultivated only with irrigation pastoral activities dominate, and the forests disappear.
The Sahara proper begins on the southern border of the Saharan Atlas. The demarcation coincides with a diminution of the precipitation to less than 4 inches 100 mm per year. The landscape and vegetation differ greatly from those in the north, with life and activity limited to a few privileged locations. Daily and annual temperature ranges are even more extreme than on the High Plateau, and precipitation is marked by greater irregularity. Three years may pass without precipitation in the Tademat region, as many as five years on the Ahaggar plateau.

Assessment, Restoration and Reclamation of Mining Influenced Soils covers processes operating in the environment as a result of mining activity, including the whole spectra of negative effects of anthropopressure and the environment, from changes in soil chemistry, changes in soil physical properties, geomechanical disturbances, and mine water discharges.
Mining activity and its waste are an environmental concern. Knowledge of the fate of potentially harmful elements and their effect on plants and the food chain, and ultimately on human health, is still being understood. Therefore, there is a need for better knowledge on the origin, distribution, and management of mine waste on a global level.
This book provides information on hazard assessment and remediation of the disturbed environment, including stabilization of contaminated soils and phytoremediation, and will help scientists and public authorities formulate answers to the daily challenges related to the restoration of contaminated land.
Soil scientists, geologists, ecologists, environmentalists, mining engineers and public administrators and other professionals who are involved in past and present mining activities, environmental surveillance and management.
