About Posavina

Posavina refers to the riverine region along the Sava River, here associated with Croatia’s Brod-Posavina County. It is a lowland floodplain and corridor shaped by the Sava’s course and its tributaries.

The area is characterised by agricultural land, river towns and wetland habitats that have historically supported river transport and local farming economies. Modern infrastructure and flood-control works coexist with seasonal floodplain dynamics.

Geographically the Croatian part of Posavina runs along the Sava in eastern Croatia, bordering Bosnia and Herzegovina to the south and linking regional centres along the river corridor.
