**6. Conclusion**

Northern Africa is one of the world's most water-scarce regions. The freshwater resources in Northern Africa region are limited. Due to many factors including population growth, recurrent and frequent droughts over the last 4 decades and poor freshwater management, water demands will increase to satisfy different human uses such as irrigation purposes. Thus, water scarcity in the region is going to increase in future years and be more worsen. Hence the need to embrace the best water managing demand and through several unconventional water resources such as reuse of drainage wastewater, seawater desalination and rainwater harvesting. Indeed, managing water scarcity in Northern Africa in a sustainable, efficient, and equitable ways is paramount to tackling Northern Africa's water stress.
