Abstract

This study evaluates the strategic importance of gray water, which is a component of virtual water, defined as “the water embedded in key water-intensive commodities such as wheat” or “the water required for the production of commodities.” Estimation of gray water plays a role in ensuring water and water-dependent food security for both importing and exporting countries. Methodologies towards reducing virtual water for strategic crops in the Tunisian semi-arid region include irrigation techniques and the control of runoff. Resources management practices that improve family income especially for women and children, all contribute to food security.
