On a warm January afternoon in southern Ethiopia, thousands of ill-tempered livestock stand in groups with the pastoralists who have guided them for dozens of miles to drink. The animals dot an expansive field of Acacia trees, severed bits and pieces of dead grass and dust.
Earlier in the day thousands of young goats, sheep and calves took turns to have their fill of water. And the show will not end with the cattle; camels are still waiting in line. For being the best able to resist drought, now they will be last.
