Water, which is a key input for life and cannot be substituted for many of its functions, has economic as well as social and cultural values. Water demand is being increased due to growing population and scarce resources and increasing competition among water-using sectors is being aggravated, globally. Meeting the needs for food in the future is under risk due to non-uniform distribution of water resources all over the world, increasing competition for decreasing water resources, system performances far from expected, inefficient and uneconomic use of water in irrigation, and continuity of problematic trend. The situation will motivate a new approach, which treats water resources management as integrated, based on economic efficiency and the functions of conventional water resources management practices should be inquired. Food security for the future will always depend on population stability, sustainability in economic and social development, and integrated water resources management (IWRM) strategies.
