Water scarcity and food security: the role of virtual water flows in cereals trade in the north Africa countries [electronic resource].

Includes reference.

North Africa is one of the driest regions in the world. Consequently, all countries in the region depend mainly on agricultural imports to achieve the food security. The present study endeavor to estimate: firstly, the national and the global water saving achieved through the North African international cereal trade by using the concept of virtual water trade. Secondly, the relation between the imports of cereal trade, as endogenous variable, and the available water resources availability with other important factors as exogenous variables.
