The main objective of this project is to develop the scientific basis for an integral management plan of water resources and their use in the Jordan Valley. Specific objectives are : * Development of a GIS-based database containing harmonised sets of population, land use, soil and water data of the Jordan Valley, including consistent sets of maps that project distribution of water sources and users. * Projection of potential available sources and demand of water until about 2030. * Assessment of the hydrogeological conditions, including a conceptual model for assessing environmental and health risks of current practices on soils and groundwater. * Identification of environmental and health risks of water quality degradation. * Evaluation of water collection, storage, delivery and irrigation practices and development of scenarios for water and soil management, regarding different land use practices. * Formulation of an optimisation model for water use, considering utilisation conflicts and potentials of conjunctive water uses
