12.  Mechanism of climate change and paleo climate  Decision system (on GIS)for selecting an alternative solution  Strategic tool for resources planning and development  Complete the system with others data ( pipelines and others hydraulics infrastructure  To put system on the web R&D : PROJECT 12

13.  The project outputs are: - A detailed paleoclimate of Morocco to understanding The mechanisms of groundwater recharge deep south of Morocco in the precipitation of Morocco does not exceed 100 mm. - Development of a climate prediction system based on global sytems (World clim, FAO Clim, NASA) - Development of a GIS water containing several thematic layers: spatial data, administrative boundaries, infrastructure, land use, satellite imagery, digital terrain models, Geology, Climatology, Hydrology, Hydrogeology

16. 16  The objective of the project was the feasibility study of using Brakish water (15 g/l) to supply the city of Tantan instead of using sea water desalination.  The project was conducted with EMI and consisted on Geological, hydrological and hydrological studies, completed by isotopic analysis long term pumping test.

18. 18  The finding of the research is : The large reserves of brackish fossil water in the Cretaceous basin constitute a real alternative, much more interesting than the desalination of sea water  This project has resulted in savings more than US $ 2.5 million in terms of investment and more economic in terms of operating  The solution is also environmentally interesting: - Less Brine - Less GHG Emission

19.  ONEE as water utility is impacted by CC  ONEE’s strategy to cope with CC is based on  Demand Management  Use of unconventional water resources  R&D and capacity building  ONEE strategy is part of an overall government strategy for IWRM and CC 19
