• The emphasis from land to water with new guidelines for water management.

• Water allocation to more water-efficient techniques.

• Current land use, cropping patterns, and germ plasm to be more water-

efficient.

• The way water is valuated to truly reflect the scarcity conditions.

• Trade policies to import goods with high water demand for production.

• The attitude toward regional cooperation.

• Policies to address water scarcity issues.
