1- MENA Desalination Research Network (MEDEREN): It has the same concept as the national network. The only difference is that REDEREN is developed at the level of MENA region. Therefore, it will include experts from different MENA countries. Connections with existing sub-regional or national networks will be established (e.g. Moroccan Society for Membranes and Desalination, Tunisian Desalination Association, etc.). The main activities will consist in one regional workshop per year and one regional report per year. Apart from the workshop, a mailing list and an intranet solution will be proposed to exchange and organize periodic discussions. This regional network will be launched by 2017.
