Three years ago, the vast marshlands of southern Iraq’s Dhi Qar province were flourishing. Fishermen glided in punts across swathes of still water between vast reed beds, while buffalo bathed amid green vegetation. But today those wetlands, part of the vast Mesopotamian Marshes, have shriveled to narrow channels of polluted water bordered by cracked and salty earth. Hundreds of desiccated fish dot stream banks, along with the carcasses of water buffalo poisoned by saline water. Drought has parched tens of thousands of hectares of fields and orchards, and villages are emptying as farmers abandon their land.
