The proceedings of the NATO Advanced Research Workshop "Wastewater Reuse - Risk Assessment, Decision-Making and Environmental Security" , held in Istanbul, Turkey, October 12-16, 2006 will provide information to the readers involved with water management, wastewater, salinity, environmental issues, economists, social workers and insurance groups. The book has information on the current situation of water management in the world and especially the Middle-east and Mediterranean regions; it addresses some of the most difficult international conflicts. Wastewater is a by-product of agricultural, industrial or domestic water use, and can be an environmental hazard causing damage to soil and to water resources. However, as demonstrated in many of the papers, it can also be a benefit if exploited correctly. Papers presented cover in great detail and depth the risk assessment, decision-making approaches and environmental security. Information about design, installation, management of wastewater treatment facilities, and use for saline water are provided by experts from the European Union, UNESCO, World Bank, United States, Canada and other contributing agencies dealing with the water scarcity situation. Forty five (45) selected papers are included in this publication. This is a great contribution added to the advancement of science and technology; it is also hoped that this meeting and publication will foster the creation of professional and personal links among scientists and will stimulate exchange visits and development of cooperative research projects by the participants and the readers. The available materials will help readers to collect any desired information, activate their own program, and seek help from the experts in the field. This ARW, fully funded by NATO, provided the participants a stage to meet 63 people from 20 countries and discuss important issues.
