This is the end of this blog, and I am very happy to have written it along this term. Globally it widened my knowledge about the relationship between Africa and water resources. I knew that I had shortcomings about this continent, and they were partly confirmed as reality. Africa suffers from droughts and decline of water resource availability. But, my shortcomings were completed by a panel of other dynamics that I couldn't suspect. In the same way that environmental changes affect intensively human activities in this Continent, we can also notice that humanity also generates consequences on environment (what we can see in the case of Lake Victoria for example). As there is a close connexion between people and environment resources in Africa, interactions between both are more intense. For instance, in Europe countries like UK, if precipitation decreases, you generally still have food, or still have your job. Because people's life are disconnected to environment where the

We saw in the previous posts that climate change has had an huge impact on Africa, in general. I find it relevant to stay on the same region as in previous posts because it illustrates a lot of contrasts that this continent faces. -Actual situation : The continent of Africa is tremendously touched by climate change through extreme events like droughts and floodings, driving its natural environment to be degradaded, particularly in the form of desertification. In this way, we will see that various aspects of north-west of Africa can be characterized as interacting each other. Hydrology interactions: African hydrology is changing from these last decades. T he global rate of precipitations in the northern regions of North Africa have demonstrated a significant decrease ( Isabelle Niang et al ., 2014) and the african climate is now characterized by extreme events. Succession of droughts and floodings leads to the degradation soils, driving them to increase the a
