For thousands of years, two famous rivers, the Tigris and Euphrates, made Iraq one of the most fertile regions in the Middle East. Often called "the cradle of civilisation", the first urban settlers grew up on the lands between the two ancient waterways. But today, things are dramatically different, - for the rivers and the people who depend on them. The Tigris and Euphrates meet in Basra province, in the south of Iraq, where they form the Shatt al-Arab waterway. Tens of thousands of Iraqis live in marshes, like Abu Haider and his wife who rely almost entirely on fishing to survive.
