Thames River

54 BCE - 2010 CE

Though the Thames covers less than 10% of England and Wales, the river basin is home to nearly a quarter of the region’s population (around 14 million people). Ecosystems of the river basin include chalk streams, marshlands, and the Greater Thames estuary at the North Sea, all of which are threatened by agricultural pollution and urban run-off. Climate change is likely to exacerbate flood risks in the Thames river basin while also reducing water availability.
