Came on this timeless agricultural scene years ago while traveling in West Sumatra. The farmer is a member of the Minangkabau ethnic group - the world's largest matrilineal society - and he is plowing his rice field with a "kabau", or water buffalo. The ceremonial "keris" dangling off his belt in the back is a nice touch. [NOTE: In Minangkabau communities, property, e.g. rice fields, are controlled by and passed down through the female lineage].
