In this Sept. 30, 2013 photo, an Ashaninka Indian boy pauses to pose for a photo as he returns on foot to his home after shopping in the nearby village Kimkibiri Baja, Pichari district, Peru. Kimkibiri Baja, one of 350 Ashaninka communities, lies in the Apurimac river valley, the No. 1 coca-producing valley in the world, sharing the world's top coca-growing valley with drug traffickers, rebels, illegal loggers and, now, an increased military presence.
