As I was reading about medieval guilds in the islamic wolrd and how towns were organized. In a section they talked about how empheral towns in the muslim world. I realized one of the key differences between somalia and other arid countries is that while we might get slightly more rain . We don't have any permanent water source such as an oasis. So outside of somewhere like harar or mogadishu. You couldn't permanent settle anywhere. Its why somalis didn't raise cattle like other nomads in the sahel or why we have less dialects and a more cohesive identity. Enrico centurllo in a paper mentions centuries where rainfall was much higher. I suspected that coincided with much higher rates of town settlement.
