Nomads and their camels trek long distances every week from the harsh low-lying deserts to barter with Amhara and Oromo farmers living in the fertile highlands. All manner of farm produce, livestock and household items are offered for sale. Frankincense is an aromatic resinous gum obtained from a species of Boswellia tree, which thrives in the barren Horn of Africa.Markets are important commercial and social occasions for those people living in scattered rural communities..
