The article concerns the Sahel that is vast area between Sahara on North and Sudan on South. On this area, poor and unstable states (Senegal, Somalia, Mauritania, Mali, Niger, Chad, Sudan and Ethiopia) are situated. From the end of 60's to the end 80's of the 20th century the Sahel was the place of dramatic events caused mainly by economic and political factors connected with negative climatic changes (long droughts). This period has been characterized by war and bloody conflicts (e.g. in Darfur). The situation till nowadays did not improve and there are lack of perspectives to solve existing conflicts.
