The study mainly aimed at study the effects of climatic changes on the Nile Valley African Countries and on Egyptian freshwater through achieving the following sub-objectives: (1) to learn about the concepts and definitions of climate changes and global warming, and the reasons that led to them. (2) Studying the effects of climate change and global warming on the Nile Valley African Countries and on Egyptian water resources. (3) Studying the effects of climatic changes on the Egyptian coastal beaches. (4) A study For economic integration between Egypt and the Nile Valley African Countries. The most important findings of the study were strengthening the implementation of the multi-hazard early warning system: it is an important mechanism for collecting and analyzing information on the various risks and threats associated with climate change, and working to nominate the best possible and potential paths to deal with them efficiently, accelerating the establishment and activation of national frameworks for climate services: which is contributes to enhancing the involvement of various stakeholders and will develop and distribute climate services to support government policies and strategies to deal with climate change.   Adopting a practical approach to climate adaptation in Africa: It includes strengthening the capacity of African countries with regard to climate analysis and providing climate services through the relevant national institutions, identifying and selecting priorities for climate action, and formulating and implementing national climate-related policies, including the most climate-sensitive goals of the sustainable development goals, Availability of financial support from the international community: It is necessary to enhance the ability of countries to fully implement the contributions set for them at the national level, This support can be achieved through several sources, perhaps including capacity building, technology transfer, grants and soft loans, Developing new varieties of agricultural crops that bear high temperature, salinity and drought, which are the conditions that will prevail under conditions of climatic changes, developing new varieties whose growing season is short to reduce the necessary water needs for them, changing planting dates to suit new weather conditions, as well as cultivating suitable varieties in appropriate climatic regions. It has to increase the crop yield per unit water for each crop, and to move in three parallel paths: It is represented in the national track by adopting relevant national plans and policies, whether by adapting to climate change or mitigating the risks and threats inherent to it. It lies in adopting joint arrangements and policies based on environmental coordination to reduce the risks of climate change. It consists of supporting the various international frameworks concerned with combating climate change and enhancing coordination with various international parties in this regard.
