An old Dassanech man wearing a traditional ivory lip ornament. The old practice of piercing the flesh below a man's lower lip for decorative purposes is fast dieing out.The Dassanech people live in the Omo Delta of southwest Ethiopia, one of the largest inland deltas in the world. It is also one of the least accessible and least developed parts of East Africa. As such, the culture, social organization, customs and values of the people have changed less than elsewhere.The Dassanech speak a language of Eastern Cushitic origin. They practice animal husbandry and fishing as well as agriculture.
