evidence: Bosnia and Herzegovina is in the western Balkans, bordering Croatia (932 km or 579 mi) to the north and west, Serbia (302 km or 188 mi) to the east, and Montenegro (225 km or 140 mi) to the southeast. It has a coastline about 20 kilometres (12 miles) long surrounding the town of Neum.[127][128] It lies between latitudes 42° and 46° N, and longitudes 15° and 20° E. [...] Overall, nearly 50% of Bosnia and Herzegovina is forested. Most forest areas are in the centre, east and west parts of Bosnia. Herzegovina has a drier Mediterranean climate, with dominant karst topography. Northern Bosnia (Posavina) contains very fertile agricultural land along the Sava river and the corresponding area is heavily farmed. This farmland is a part of the Pannonian Plain stretching into neighboring Croatia and Serbia. The country has only 20 kilometres (12 miles) of coastline,[127][130] around the town of Neum in the Herzegovina-Neretva Canton. Although the city is surrounded by Croatian peninsulas, by international law, Bosnia and Herzegovina has a right of passage to the outer sea.
