The Sahel region is one of the most environmentally endangered regions in the world. Climate change modifies climate patterns, increases the average temperature, creates anomalies in precipitation and increases the probability of droughts. The consequences of these changes are the degradation of environment and natural resources, which lead to scarcity. Because of the strong dependence of the Sahelian population on the environment, this represents a threat to survival; therefore these groups compete over the ownership of resources, which often results in group cohesion and discrimination against opposing groups. Consequently, conflicts arise. In the master's work, the conflicts in Sahel are presented through the theoretical models of the Toronto and Swiss schools, which combine the above environmental factors, in combination with social factors, into a causal relationship. The aim of the master's thesis is therefore to examine the extent to which climate change influences the formation of conflicts in the Sahel.
