A woman from the Bena tribe eats honey collected from a tree in Ethiopia's southern Omo Valley region near Turmi on September 20, 2016. The Bena are a Nilotic ethnic group in Ethiopia and known for keeping bees. The construction of the Gibe III dam, the third largest hydroelectric plant in Africa, and large areas of very "thirsty" cotton and sugar plantations and factories along the Omo river are impacting heavily on the lives of tribes living in the Omo Valley who depend on the river for their survival and way of life. Human rights groups fear for the future of the tribes if they are forced to scatter, give up traditional ways through loss of land or ability to keep cattle as globalisation and development increases. / AFP PHOTO / CARL DE SOUZA
