Cairo-The challenges faced by Egypt in the water sector are similar to those faced by most arid and semi-arid countries around the world at both national, regional and international levels. Most of them suffer from water scarcity and/or are vulnerable to climate change. Moreover, in some arid countries like Egypt, due to their geographical position , rivers originate from outside their borders. Those challenges and others result in increasing water scarcity and threatening water security. Egypt’s water is the most important pillar for achieving national security. The comprehensive sustainable development plans in all fields are linked to the state’s ability to provide the necessary water resources to implement these plans. Therefore, the decision of the State was to organize the “Cairo Water Week”. The Cairo Water Week is considered as the biggest water-related event in Egypt and is planned to be organized annually by the Ministry of Water Resources and Irrigation in collaboration with national, regional and international partners. It aims to promote water awareness and foster innovative approaches to face the most pressing water-related challenges, keep updated on global movements to address water challenges and identify modern tools and techniques for managing water resources. The Week starts its first edition his year around the Main Theme “Water Conservation for Sustainable Development”, it will take place in Cairo, Egypt during the period from 14-18 October 2018 under the patronage of H.E. Mr. Abdel Fatah El-Sisi, President of the Arab Republic of Egypt.
