An initiative towards water saving: Non-conventional water resources as an additional irrigation water source

  1. 1. An initiative towards water saving: Non-conventional water resources as an additional irrigation water source by Atef Hamdy Emeritus Professor, Water Resources Management Ciheam/MAIBari, Italy
  2. 2. Water resources: the dominant facts The dominant fact that will be strongly evident over the next few decades in the structural imbalance between the constantly increasing demand for water to meet the needs and the limited natural available water supply : A) Water Resources Dilemma in the Mediterranean Region. B) Managerial Capacity Building Most developing countries in the Mediterranean are suffering big shortages in the water managers who are capable not only to evaluate the problem, but, to find the reasonable solutions; those with good understanding to integrate ecological and human water needs in a comprehensive way.
  3. 3. The 3 approaches 1- by increasing the efficiency with which current needs are met 2- by increasing the efficiency with which water is allocated among different uses 3- by introducing non-traditional sources of supply including, saline, reclaimed or recycled water and in some limited circumstances, desalinized brackish water or seawater

Reuse of Treated Wastewater for Irrigation of Cereals, Forage and Vegetables by Means of Different Irrigation Methods (Agadir, Morocco) 2. Recycling of Drainage Water for Sustainable Irrigated Agriculture (Western Nile Delta, Egypt) 3. Sustainable Use of Highly Saline Water for Irrigation of Crops Under Arid and Semiarid Conditions (Adana, Turkey) 4.

  15. 15. 4th World Water Forum 20 March 2006 Water Use Efficiency in Agriculture and Potentials for Water Saving in the Middle East Region Regional Action Programme on “Water Resources Management” Conclusion In order to move from WATER SCARCITY to WATER SECURITY, the following Local Actions should be generalised to the whole region: 1. Collect, treat and reuse every single drop of wastewater and drainage water; 2. Increase the Water Use Efficiency (more “crop per drop”) through: • the use of modern irrigation systems (sprinkler irrigation, drip irrigation), • Deficit irrgation, • Supplemental irrigation, • Water harvesting. 3. A more efficient, equitable water allocation through the use of new technologies for water distribution at farm-level (AcquaCard). Atef Hamdy
